Description

Multifaceted display

Embodiments of the invention relate to a multifaceted display. Background technique

With the rapid development of display technology, as one of display devices, liquid crystal displays (LCDs) have become the mainstream in the field of flat panel display. The LCD is realized by an electric field formed by two sheets of conductive glass to drive the liquid crystal therebetween. Since the liquid crystal itself does not emit light, the LCD needs to transmit or reflect the display through an external light source. Most of the existing LCDs are transmissive, and for transmissive LCDs, backlights are an integral part.

At present, there are many places where monitors are needed (such as hypermarkets, financial venues, basketball halls, soccer stadiums, etc.). In these places, multiple monitors facing different directions are usually fixed together and placed above the venue to make directions. People can see what the display shows. In this way, several complete displays are working at the same time, and several of the backlights are also working at the same time, so that the heat generated by the backlight is easy to accumulate, which may cause damage to the display and waste energy. Summary of the invention

An embodiment of the present invention provides a multi-faceted display including a plurality of liquid crystal display panels facing a plurality of directions, wherein the plurality of liquid crystal display panels define a receiving space, and the receiving space is provided with the plurality of liquid crystal display panels The liquid crystal display panel provides a light source of light.

For example, in the multifaceted display according to another embodiment of the present invention, the light source is a strip light source that emits light to the periphery, and the light source is parallel to any one of the plurality of liquid crystal display panels.

For example, in the multi-face display of another embodiment of the present invention, the distance from the center of the light source to each of the plurality of liquid crystal display panels is equal.

For example, in a multi-faceted display according to another embodiment of the present invention, the plurality of liquid crystal display panels are connected together by a peripheral plastic frame, and the peripheral plastic frame includes a plurality of receiving portions for accommodating the liquid crystal display panel and a plurality of A connection portion that connects the accommodation portions to each other.

For example, in the multifaceted display according to another embodiment of the present invention, each of the plurality of liquid crystal display panels is attached with an optical film on a surface close to the light source. For example, in a multi-faceted display according to another embodiment of the present invention, the liquid crystal display panels are three, and the three liquid crystal display panels are respectively disposed in three housing portions of the peripheral plastic frame, three of the three The liquid crystal display panel is connected end to end to form a triangular prism structure.

For example, in a multi-faceted display according to another embodiment of the present invention, the liquid crystal display panels are four, and the four liquid crystal display panels are respectively disposed in four receiving portions of the peripheral plastic frame, and the four The liquid crystal display panel is connected end to end to form a quadrangular prism structure.
