Embodiment
Fig. 1 shows the sectional view according to the pen recorder of embodiments of the invention.With reference to Fig. 1, pen recorder 10 comprises transparency carrier 12 and 14, be respectively formed at transparency electrode 16 and 18, the display layer 20 on substrate 12 and 14 and be stacked in photoconductive layer 24 on the display layer 20, has wall 22 between display layer 20 and the photoconductive layer 24.Electrode 16 and 18 is separately positioned on display layer 20 and the photoconductive layer 24.Display layer 20 and photoconductive layer 24 use fluid sealant 26 sealings.In addition, light absorbing zone 28 is clipped between photoconductive layer 24 and the electrode 18.Wall 22 prevents the mixing of display layer 20 and photoconductive layer 24.Wall 22 can utilize light absorbing zone to realize.Wall 22 is preferably made by the material that shows high as far as possible specific inductive capacity, raises to prevent driving voltage, but is not limited to any specific material.
Fig. 2 schematically shows the register according to embodiments of the invention.Register 30 records the information in the pen recorder shown in Figure 1 10.With reference to Fig. 2, register 30 comprises: shell 32, and pen recorder 10 supports or is arranged on wherein; Component feeding 34,36 and 37 imposes on electrode pair 16 and 18, first light source 38 of pen recorder 10 by these component feedings with voltage, is used at pen recorder 10 writing informations; With secondary light source 40, the record that the pen recorder 10 that is used for resetting produces.Component feeding 34,36 is connected with power supply with 37, and this power supply is not shown.
Fig. 3 shows the planimetric map that has write down the recording of information device.This information is with the form of (for example) character or image record.
Fig. 4 shows the planimetric map of the electrode 18 that is included in the pen recorder 10.Electrode 18 is divided into a plurality of sub-electrode 18A.These sub-electrodes 18A forms the shape of similar belt.Preferably, the width of sub-electrode 18A is equal to or greater than 1cm.Atomic slit (microscopic gap) 18B is between two adjacent sub-electrode 18A.Preferably, slit 18B is equal to or less than 50 μ m.Because slit 18B is little of 50 μ m or also littler than 50 μ m, therefore slit 18B can not regarded as the striped on the screen picture.
Fig. 5 shows the planimetric map of the electrode 18 in the pen recorder 10 that is included in modified example.With reference to Fig. 5, electrode 18 is divided into a plurality of sub-electrode 18A.The opposite end of these sub-electrodes 18A is curve shape (or flexuose).(that is, slit 18B) shape will as far as possible optionally form, thereby prevents to regard slit 18B as on the screen picture striped in the opposite end of sub-electrode 18A.
Fig. 6 shows electrode 16 in the pen recorder 10 that is included in modified example and 18 sectional view.With reference to Fig. 6, the direction of electric field (regard it as vector and induct between electrode pair 16 and 18) and the surface of substrate tilt.In this case, electrode 16 is divided into a plurality of sub-electrode 16A, and electrode 18 is divided into a plurality of sub-electrode 18A.Sub-electrode 16A and sub-electrode 18A relative to each other misplace, and the direction of the electric field of inducting between each sub-electrode 16A and each sub-electrode 18A and the surface of substrate tilt.Information can be imprinted on the part corresponding with slit 16B and 18B of display layer, although this part is unfavorable.Slit 16B and 18B can not be apparent in the image boldly.Under situation shown in Figure 5, only disperse arbitrarily, so slit 18B can not manifest boldly.Under situation shown in Figure 6, it is dull that light can become, so slit 16B and 18B can not manifest boldly.
Below, introduce the operating process of the pen recorder 10 shown in Fig. 1 with reference to Fig. 7 A to 12.Display layer 20 shown in Fig. 1 is made by cholesteric crystal.Fig. 7 A and 7B show the ordered state of cholesteric crystal molecule.Cholesteric crystal enters the focal conic state shown in the flat state shown in Fig. 7 A or Fig. 7 B.Under flat state or focal conic state, even without the electric field of inducting, it is stable that cholesteric crystal also keeps.Under flat state, owing to incident light reflects from liquid crystal, so human eye can be seen reflected light.Under focal conic state, incident light passes liquid crystal.Because the light absorbing zone 28 that is comprised separates mutually with liquid crystal layer, therefore can show black down at focal conic state (focal conic state).
Under flat state, the light that wavelength is suitable with the pitch of the helical structure of being made up of liquid crystal molecule is reflected.The light wavelength λ of maximum reflection is given λ=n * p, and n represents the average reflection coefficient of liquid crystal herein, and p represents pitch.And reflected waveband Δ λ increases with the aeoplotropism Δ n of the reflection coefficient of liquid crystal with being directly proportional.
Fig. 8 A, 8B and 8C show the characteristic (voltage and time relation) of cholesteric crystal to voltage, and this voltage applies in order to drive cholesteric crystal.When having inducted highfield in the liquid crystal, the helical structure of liquid crystal molecule suffers to destroy completely, and all molecules enter sexual state (homotropic state) in the same way, in other words, arranges along the direction of electric field.Among the figure, H represents sexual state in the same way.
When electric field rapidly disappeared under sexual state in the same way, the screw axis of liquid crystal molecule became perpendicular to electrode.Liquid crystal enters flat state, and in this state, the light that wavelength is equivalent to pitch has been subjected to selective reflecting (Fig. 8 B).In Fig. 8 B, P represents flat state.
On the other hand, suppose after the loose electric field of faint the screw axis that only make liquid crystal molecule of having inducted electric field to be disappeared (Fig. 8 A), perhaps hypothesis has been inducted after the highfield, makes electric field slowly disappear (Fig. 8 C).In this case, the screw axis of liquid crystal molecule becomes parallel with electrode.Liquid crystal enters focal conic state, and light passes liquid crystal in this state.In Fig. 8 C, FC represents focal conic state.
After the electric field of medium tenacity of having inducted, if electric field is rapidly disappeared, then flat state and focal conic state coexistence.This can realize that Neutral colour shows.As described above, cholesteric crystal is bistable.This phenomenon can be used for display message.
Fig. 9 shows the characteristic (relation of reflection coefficient and voltage) of the reflection coefficient of cholesteric crystal.Fig. 9 schematically shows required response time of cholesteric crystal response voltage and the top response time of introducing in conjunction with Fig. 8 A, 8B and 8C.(left part by Fig. 9 is represented when the original state of cholesteric crystal is flat state, promptly, relevant with high reflectance), if pulsating volage is elevated to a certain scope, this pulsating volage drops within the scope of the driving voltage that makes cholesteric crystal enter focal conic state (relevant with the low reflection coefficient among Fig. 9).If pulsating volage further raises, it has dropped within the scope of the driving voltage that makes cholesteric crystal enter flat state (being illustrated and relevant with high voltage by the right part of Fig. 9).
(left part by Fig. 9 is represented when the original state of cholesteric crystal is focal conic state, and it is relevant) with low reflection coefficient, along with pulsating volage raises, this pulsating volage falls within the scope of the driving voltage that makes cholesteric crystal enter flat state gradually.
Figure 10 is the synoptic diagram about the operation of the pen recorder shown in Fig. 1 10.Electrode 16 and 18 is carried by substrate 12 and 14 respectively, and is connected with power supply 42 by component feeding (contact). Substrate 12 and 14 can be made by glass.Preferably, substrate 12 and 14 is by making such as the flexible material of film (film), and it is folding that pen recorder is resembled the paper, and resembles and carried by the user the paper, perhaps can be crooked to carry out record.
But, photoconductive layer 24 is not limited to the OPC of functional separation, but can be made by the single-layered OPC that one deck and generation and delivered charge are only arranged.Single-layered OPC adopted a lot of years, and is longer than the time of the OPC that adopts functional separation, and is considered to show the relatively poor property improved.But, with regard to consider be applied in single-layered OPC on the pen recorder 10 with regard to because that single-layered OPC can not resemble when being applied on the printer wearing and tearing is so big, therefore also can adopts single-layered OPC, and not have what influence.
Suppose that light L optionally shines on the photoconductive layer 24, has voltage to be applied on electrode 16 and 18 simultaneously.In this case, on the adjacent part of the part of photoconductive layer that high voltage is applied to liquid crystal and light L irradiation, and not have on the adjacent part (middle body among Figure 10) of the part of the photoconductive layer that shines with light L that low-voltage is applied to liquid crystal.Like this, the state of liquid crystal can be controlled by the elective irradiation of light.
Figure 11 and 12 shows the display characteristic (reflection coefficient) of the pen recorder 10 of the combination with cholesteric and photoconductive layer.Figure 11 and 12 and Fig. 9 similar.
Figure 11 to show the display characteristic that shows between the tour from the flat state to the focal conic state light-struck the time having with the characteristic that does not have to show light-struck the time with comparing.Curve A is represented the display characteristic that shows light-struck the time, and curve B shows and do not have the display characteristic that shows light-struck the time.When light shone, in case pulsating volage surpasses some threshold value Vtf, liquid crystal layer carried out the transformation to focal conic state.Suppose that the voltage that makes liquid crystal enter focal conic state fully is voltage Vfc, if voltage becomes and is equal to or higher than voltage Vfc so, then liquid crystal layer reenters flat state.
Do not having light-struck the time, making liquid crystal layer carry out all being higher than situation when rayed is arranged to the threshold value Vtf ' of focal conic state conversion and the voltage Vfc ' that makes liquid crystal layer enter focal conic state fully.
Required voltage required voltage when not having rayed compares when supposing rayed is arranged.The voltage Vfc that makes liquid crystal enter focal conic state when rayed is arranged is lower than makes liquid crystal carry out the threshold value Vtf ' that changes to focal conic state when not having rayed.That is, apply voltage Vfc and cause light-struck that part of liquid crystal to carry out transformation, but do not have light-struck that part of liquid crystal to remain under the flat state to focal conic state.
Figure 12 to show the display characteristic that shows between the tour from the focal conic state to the flat state light-struck the time having with the characteristic that does not have to show light-struck the time with comparing.Curve C is represented the display characteristic that shows light-struck the time, and curve D shows and do not have the display characteristic that shows light-struck the time.When light shone, if the voltage that is applied has surpassed voltage Vtp, then liquid crystal carried out the transformation to flat state.If the voltage that is applied has become voltage Vp, then liquid crystal has entered flat state fully.
When not having light-struck the time, if the voltage that is applied has surpassed voltage Vtp ', then liquid crystal carries out the transformation to flat state.If the voltage that is applied has become voltage Vp ', then liquid crystal enters flat state fully.Even in Figure 12, be similar to Figure 11, driving voltage also depends on whether rayed is arranged and great changes will take place.Liquid crystal is subjected to light-struck part and carries out transformation to flat state, does not enter focal conic state and liquid crystal is subjected to light-struck part.Like this, even applied identical voltage, it also is different with the arrangement mode that is not subjected to liquid crystal molecule between light-struck part that liquid crystal is subjected to light-struck part.Utilized this phenomenon to write down character or image just.
Figure 13 shows being connected of register 30 and the information processing terminal 44 among Fig. 2.Register 30 is from personal computer or any other the information processing terminal 44 reception information, and writes information in the pen recorder 10.Register 30 is controlled by personal computer or any out of Memory processing terminal 44.
First light source 38 that is used to write down use led array or semiconductor laser along pen recorder 10 laterally light shine on the pen recorder 10 continuously in move.In addition, first light source 38 pen recorder 10 vertically on move, as shown by arrows so that pen recorder 10 is scanned.In addition, also can be that pen recorder 10 moves and first light source 38 is maintained fixed.By using led array, cheaply and simply realized first light source 38.
Secondary light source 40 is the light sources that are used to reset.Secondary light source 40 be to use can uniformly light-emitting LED, organic field luminescence lamp or fluorescent light realize.And any one in these assemblies can be used in combination with light guide plate.Deletion record on pen recorder 10 information or say so pen recorder 10 carried out so-called resetting in, secondary light source 40 is luminous on a large scale, to light shine on the photoconductive layer 24.Shine equably when coming out from secondary light source 40 at light, fluctuating signal is applied on the electrode 16 and 18 of pen recorder 10 by feed-in assembly 34 and 37.Thereby, flat state is arrived in the liquid crystal full recovery.
Why will light shine the reason that resets on the photoconductive layer 24 is, when illumination was mapped on the photoconductive layer 24, the impedance that is provided by photoconductive layer 24 reduced, and imposes on apparent voltage (apparent voltage) decline of liquid crystal.When illumination is mapped on the photoconductive layer 24,, just can make liquid crystal be initialised to flat state by applying low-voltage.Even do not comprise secondary light source 40, as long as apply high voltage, also can be with liquid crystal drive to flat state.But, when especially the size of pen recorder is very big, after having applied voltage, can instantaneously flow through big electric current.This is a danger close for safety.Therefore, light-struckly simultaneously liquid crystal being applied the relatively low voltage liquid crystal of resetting by having, is more favourable with regard to safety.But, 24 long-time irradiations can cause tired and the decline of photoconductive layer 24 performances light to photoconductive layer.Therefore, the rayed of being undertaken by planar light source basically should be just to the purpose that resets, and should finish in the short as far as possible period.
On the other hand, in general first light source 38 (led array) that writes down use has such feature: focal length is little, and often misalignment focus.Therefore, preferably, make the focal length of first light source 38 adjustable.The focus of first light source can manually or automatically be regulated.
In order to carry out record, 10 of first light source (led array) 38 or pen recorders scan on sub scanning direction.Depend on and move still by led array pen recorder moves, register designs is become following two types any.
Figure 14 shows the stereographic map of an example of flatbed recorder.Register 30 has such feature: can see in real time that the information and this register that are recorded on the pen recorder 10 are very thin.The thin outer crust 32 that looks like a board has the base for supporting of laying pen recorder 10.First light source of being realized by led array 38 moves record.
Figure 15 shows first light source 38 in the flatbed recorder 30 that is included in shown in Figure 14 and blocks assembly 46.First light source 38 is positioned at pen recorder 10 belows, and rayed is to the photoconductive layer 24 that is positioned at pen recorder 10 back sides.Block assembly 46 and be positioned at pen recorder 10 tops, fall on pen recorder 10 tops to prevent ambient light.The width that blocks assembly 46 equals or is slightly larger than the width of each banded sub-electrode 18A that electrode 18 is divided into.Block that assembly 46 links together with first light source 38 and move with first light source 38.
Feed-in assembly 34 is arranged to contact with the electrode 16 of pen recorder 10, and feed-in assembly 36 is arranged to contact with the electrode 18 of pen recorder 10.In addition, feed-in assembly 37 is arranged in reseting period and begins to contact with the electrode 18 of pen recorder 10.Voltage is imposed on electrode 16 and 18.Feed-in assembly 34 is arranged to ground voltage (GND) and both had been used for record also be used to reset in the ordinary course of things.Feed-in assembly 36 and first light source, 38 same moved further, and the voltage that is used to write down applies by feed-in assembly 36.Feed-in assembly 34,36 and 37 preferably forms spherical form, perhaps forms the shape of elastic-like projection, because the load that pen recorder 10 is caused is less like this.
As mentioned above, the value of pen recorder 10 of the present invention is in electrode 16 and 18 structure of at least one.If electrode 16 and 18 is simple pulvilliform electrodes, the voltage that is applied may act on the whole pen recorder 10.This can increase because the possibility that the show state (be the non-recorded part of pen recorder and the state of recording section) of pen recorder is changed such as the effect of the such noise light of ambient light.That is, if ambient light has been fallen on the part outside the part that is being scanned by first light source 38 of pen recorder 10, the state of liquid crystal may be changed by ambient light.
In order to block ambient light fully, register must comprise barrier structure.This has reduced the compactedness and the availability of register.Therefore, at least one electrode (that is, electrode 18) a plurality of sub-electrode 18A have been divided into.Voltage imposes on each sub-electrode 18A by feed-in assembly 34 and 36.First light source 38 light shine pen recorder with the corresponding part of the sub-electrode 18A that has applied voltage on.Because do not apply voltage to remaining sub-electrode 18A, even ambient light has dropped on these sub-electrodes 18A, the state of liquid crystal can not changed by ambient light yet.In addition, block assembly 46 mobile be with the mobile interlock of first light source 38.This has prevented that ambient light from dropping on any one sub-electrode 18A that is writing.
Any one electrode in the electrode 16 and 18 of pen recorder 10 can be divided into a plurality of sub-electrodes that are in the proper range, thereby can avoid ambient light (noise light) non-recorded part or the negative effect of recording section.Can keep show state reliably.Thereby,, also can use compact register 30 recorded information on pen recorder 10, and can not be affected even, resemble a place in the room under the fluorescent light in bright place.
The size of the sub-electrode that electrode 18 is divided into was discussed.Thereby, if the slit 18B (non-electrode part) that the width of one of side of each banded sub-electrode 18A is equal to or greater than between 1cm or the adjacent sub-electrode 18A is equal to or less than 50 μ m, slit 18B is inconspicuous, and can not influence appreciable demonstration.
Figure 16 shows first and second light sources 38 in the flatbed recorder shown in Figure 14 and the sectional view of 40 position.First light source 38 that is used to write down can move along the direction shown in the arrow.In order to carry out record, apply voltage by feed-in assembly 34 and 36.First light source 38 is in that (pen recorder 10 vertically) moves along sub-direction of scanning when main scanning direction (pen recorder 10 laterally) flicker is luminous, so that pen recorder 10 is scanned.The secondary light source 40 that is used for initialization or resets is maintained fixed on the bottom of register 30 and at every turn to the whole surface irradiation light of pen recorder 10.In this case, pulsation AC voltage imposes on electrode 16 and 18 by feed-in assembly 34 and 37.Reset finish after, start-of-record.
Figure 17 shows first and second light sources 38 in the modified example of the flatbed recorder shown in Figure 14 and the sectional view of 40 position.The secondary light source 40 that is used for initialization or resets is attached at the front end of first light source 38, thereby it can be along with first light source 38 moves together.In this case, when first and second light sources 38 and 40 move, can directly finish record after finishing resetting.Version shown in Figure 17 has such advantage: reset and write down can once the circulation in finish.Thereby writing of the deletion of recorded information and fresh information can be finished in the short time period.
