Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
With reference to the structural representation that figure 1, Fig. 1 is a kind of touch-control display panel, three gate lines G n-1 of continuous arrangement are shown in Fig. 1, Gn and Gn+1, three data line Dn-1 arranged continuously, Dn and Dn+1, the corresponding electric capacity Cs of 9 pixel electrode Pix, each pixel electrode Pix.
If gate lines G n-1, Gn and Gn+1 are positioned at same display timing generator section, when Gn exports complete, the circuit of Gn+1 can feed back to the circuit on Gn, makes the voltage on Gn normally drag down closedown.If when inserting touch-control sequential section in the middle of Gn and Gn+1, when Gn exports complete, enter touch-control sequential section, the sequential of touching display screen is affected, and the circuit of Gn+1 does not have feedback, the circuit shut-in time of Gn is caused to postpone, namely to bear time of high voltage conduction elongated for Gn, repeatedly back and forth this touch-control display driver process time, dark fringe can be there is at Gn place, cause touching display screen aging, serviceable life is shorter.
Visible, insertion due to touch-control sequential section can cause upper one scan gate line to bear the time lengthening of high pressure, makes touching display screen in Long-Time Service process, accelerates the aging of specific gate polar curve, make touching display screen easily occur dark fringe at this gate line place, cause serviceable life shorter.
For solving the problem, the embodiment of the present application provides a kind of touch-control display drive method, for touching display screen, this touch control display method comprises: when carrying out the touch-control reading scan of multiple image successively, and the distributing position controlling the touch-control sequential section of described multiple image is incomplete same.Wherein, the scanning sequence of every two field picture includes: a display timing generator section and M touch-control sequential section, and a, M are positive integer; If M is greater than 1, in same two field picture, described touch-control sequential spacer segment distribution.
In the embodiment of the present application, described touch control display method is when carrying out touch-control display driver, the distributing position controlling the touch-control sequential section of described multiple image is incomplete same, touching display screen can be made like this when the touch-control reading scan realizing multiple image, cause the gate line bearing high-voltage time prolongation incomplete same owing to inserting touch-control sequential section in each two field picture, thus make different gate lines share the impact of high-voltage time prolongation, and then the time of occurrence of dark fringe can be slowed down, slow down the aging of touching display screen, increase the service life.
Optionally, the distributing position of the touch-control sequential section of the described multiple image of described control is incomplete same to be comprised: in continuous print P two field picture, and the distributing position controlling the touch-control sequential section of this P two field picture is all not identical.Wherein, P is the positive integer being not more than K ÷ M ÷ N; K is the number of the gate line of touching display screen; M is the number of times of touch-control sequential hop count in a vertical interval; N is the adaptation coefficients of setting, and N is positive integer.As N=1, P is maximum, can slow down aging to greatest extent, increase the service life.The concrete numerical value of N can adjust according to demand.
In sweep time corresponding to P two field picture in T, prior art is due in every two field picture, and the position of touch-control sequential section is all identical, so it is in each two field picture, the high pressure time delay that touch-control sequential section causes is all act on identical one or many gate lines.Wherein, when only there is a touch-control sequential section in two field picture sweep time, all images all cause high-voltage time to extend on same gate line, when there being multiple touch-control sequential section in two field picture sweep time, all images all cause high-voltage time time delay on many identical gate lines, the gate line number of high pressure time delay is identical with the number of times of touch-control sequential section, one_to_one corresponding.
The embodiment of the present application is by being arranged in continuous print P two field picture, and the distributing position of the touch-control sequential section that each two field picture is corresponding is all not identical, and like this in sweep time corresponding to P two field picture in T, the distributing position of the touch-control sequential section of each frame is all not identical.Like this, the number of the gate line originally bearing P sub-high pressure time lengthening is expanded to P doubly, aging speed has been reduced P doubly, thus effectively prevent problem of aging, substantially increase serviceable life.
Optionally, the distributing position of the touch-control sequential section of this P two field picture of described control is all not identical comprises: the distributing position controlling the touch-control sequential section of the continuous print P two field picture of described touching display screen according to the array of the side-play amount of setting is all not identical.
Wherein, described side-play amount array has the individual different element of P; In described side-play amount array, arbitrary element is i* △ T, i is the natural number being less than P; △ T is the time that described touching display screen scans separately a gate line in display timing generator section; The value of i is the numerical index value of corresponding element, and P element arranges according to the order of setting.The value of i* △ T is time offset.The minimum value of i is 0, and maximal value is P-1.
The array indexing value increasing or decreasing of each element can be set.Now, carrying out the method for touch-control reading scan to any frame image in described P two field picture can be as shown in Figure 2.
With reference to the schematic flow sheet of a kind of touch-control reading scan method that figure 2, Fig. 2 provides for the embodiment of the present application, the method for any frame image in described P two field picture being carried out to touch-control reading scan can as shown in Figure 2, comprise:
Step S11: judge that whether the change direction of described array indexing value is for increasing progressively.
Step S12: if after array indexing value corresponding for previous frame image is added 1, obtain the time offset that current frame image is corresponding.
Step S13: the shift register described time offset being write described touching display screen, drives current frame image to carry out touch-control reading scan.
As shown in Figure 2, described touch-control reading scan method also comprises:
Step S14: if the change direction of the index value of described array does not increase progressively, after array indexing value corresponding for previous frame image is subtracted 1, obtains the time offset that current frame image is corresponding.
In the reading scan of touch-control shown in Fig. 2 method, when starting to carry out touch-control reading scan, also comprising before described step S11 and judging whether described touching display screen works, if so, then enter described step S11, if not, then terminate.Can avoid like this when touching display screen is in off working state, lasting carries out touch-control reading scan, thus reduces energy consumption.
As above-mentioned, the change direction of described array indexing value is not that to increase progressively be exactly successively decrease, when above-mentioned judge array indexing value change direction be not as increasing progressively time, known described change direction is for successively decreasing, only particular value need be subtracted on the basis of index value corresponding to previous frame image and index value corresponding to current frame image can be obtained, and then obtaining current frame image to time offset, particular value can be positive integer, and in the present embodiment, particular value is 1.
Below in conjunction with diagram, the principle of work of touch-control display drive method described in the application is described, so that this touch-control display drive method how delaying senility to be described, improves serviceable life.
With reference to figure 3, Fig. 3 for the embodiment of the present application provides a kind of displaying principle schematic diagram of touching display screen.Fig. 3 is red shows 8 grids (comprising G0-G7), has 2 touch-control sequential sections, i.e. K=8, M=2 in the scanning process of a two field picture.Now P=8 ÷ 2 ÷ N=4 ÷ N.Be 1 as got adaptation coefficients N, then P=4.
If be fixed in each two field picture, twice touch-control sequential Duan Jun lays respectively between G3 and G2, and between G6 and G7.When using so for a long time, dark fringe (in Fig. 3 shown in dash area) between G2 and G3 and between G6 and G7, can be produced.
Setting scanning P two field picture altogether sweep time be T.If in the touch-control reading scan process of every two field picture, touch-control sequential Duan Jun is parked on same gate line, and the aging pressure coefficient that this gate line bears is T/1, if on average drop on P bar gate line, ideally, the aging pressure coefficient on every bar gate line is T/P.And the aging pressure coefficient received is less, the component life of gate line and connection thereof is longer.Within identical service time, aging coefficient can only be reduced by increasing P.
Work as K=8, during M=2, get N=1, now P=4, in the scanning process of continuous four two field pictures, each gate line is all only receive the impact that a time high voltage extends, and can at utmost reduce aging pressure coefficient.
In display timing generator section, the time of a scanning gate line is △ T to touching display screen separately.For touching display screen, its gate line number is at least tens, and in two field picture sweep time, the time that touch-control sequential section takies relative to display timing generator section can be ignored.
△ T=1/f/K can be thought for setting touch displaying time.F is sweep frequency.As being 60HZ for sweep frequency, resolution is 720 × 1280 (namely having 1820 gate lines), △ T=1/60/1280 second.
The shift time of each touch-control sequential section is maximum can not exceed very first time Tmax, and is not less than the second time Tmin.Very first time Tmax is the touching display screen scanning P-1 bar gate line time used, and the second time Tmin can set according to project situation, and generally getting Tmin is 0.{ in Tmin, Tmax}, setting P adjacent element difference is minimum is the side-play amount of △ T interval.As on the touching display screen that has 8 gate lines, show in a frame image time and need 2 touch-control sequential sections, then K=8, N=1, M=2, Tmin=0, can obtain P=4 by P=K/M/N.
According to the setting principle of above-mentioned array, when P frame shows, array { 0* △ T, 1* △ T, 2* △ T, the 3* △ T} of 4 side-play amounts can be set.

In the embodiment of the present application, array indexing value can be only adopted to increase progressively in every two field picture scanning process, now, if after a two field picture scanned, its array indexing value adds the maximal value that can be greater than this array indexing value after 1, then the array indexing value that next frame image is corresponding is minimum value.
In the embodiment of the present application, array indexing value can be only adopted to successively decrease in every two field picture scanning process, now, if after a two field picture scanned, its array indexing value subtracts the minimum value that can be less than this array indexing value after 1, then the array indexing value that next frame image is corresponding is maximal value.
The difference that can also arrange the array indexing value of adjacent two elements is not identical, does not namely adopt non-increasing or the mode of successively decreasing, as arranged each arrangement of elements order for { 1* △ T, 3* △ T, 0* △ T, 2* △ T} etc.
When the difference of the array indexing value of adjacent two elements is not identical, the method for any frame image in described P two field picture being carried out to touch-control reading scan comprises: the difference obtaining the time offset of this two field picture and the time offset of previous frame image; Described difference is write the shift register of described touching display screen, drive current frame image to carry out touch-control reading scan.
The element number that can also arrange in described array is 2P, and any element now in array is i* △ T, i is natural number, and the maximal value of i is P-1, and minimum value is 0.The element of formed objects all has two.Arrangement of elements can first increase, and rear reduction, also or first reduces, rear increase.This array may be used for the scanning of continuous print 2P two field picture.
Work as K=8, when M=2, N=1, when the display of 2*P frame, this array can be { 0* △ T, 1* △ T, 2* △ T, 3* △ T, 3* △ T, 2* △ T, 1* △ T, 0* △ T}.Now, the sequential of the touch-control reading scan of touching display screen can as shown in Figure 5, the sequential chart of a kind of touch-control reading scan that Fig. 5 provides for the embodiment of the present application.In Fig. 5, show the scanning sequence of 8 two field pictures (Frame1-Frame8), wherein, LCD represents display timing generator section, and TP represents touch-control sequential section.
