Embodiment 1

[0039] An array substrate such as figure 1 As shown, it includes a plurality of pixel units 16 formed by vertical crossing of gate lines 13 and data lines 14 on a base substrate (not shown in the figure), and each pixel unit 16 includes a light switch function to control the opening and closing of the pixel. The switching transistor 11 also includes a thermo-optical switch 12 with a thermally induced refractive index change;

[0040] It should be noted, figure 1 It is only a schematic description that the pixel unit includes a thermo-optic switch, and the relative size of the thermo-optic switch and the pixel unit is not described.

[0041] In order to explain more clearly, the setting method of thermo-optic switch in each pixel unit, such as Picture 8 As shown, it is a partial enlarged schematic diagram of the pixel unit. In practical application scenarios, the thermo-optical switch 12 is disposed in the pixel unit and occupies almost the entire pixel unit, which can ensure that ...

Embodiment 2

[0069] This embodiment provides a display panel, in which an array substrate in the display panel can realize the display of different color gray scales through cooperation with a color filter substrate.

[0070] Optionally, the thermo-optical switch in each pixel unit covers the entire pixel unit area to avoid light leakage.

[0071] The color filter substrate can be a commonly used color filter substrate, and a black matrix can be arranged on the color filter substrate to further avoid light leakage.

[0072] The display panel includes an array substrate and a color filter substrate. The array substrate adopts the above-mentioned array substrate. The array substrate and the color filter substrate are combined to form, and the array substrate is composed of M×N pixel units.

[0073] In this embodiment, the array substrate and the pixel unit of the color filter substrate are in one-to-one correspondence, and each pixel unit is provided with a pixel unit; the red, green, and blue pixel ...

Embodiment 3

[0077] This embodiment provides a display device, which can achieve a flat panel display effect similar to a liquid crystal display device, and has high brightness and good contrast.

[0078] Such as Figure 7 As shown, a display device includes a backlight source 3 and a display panel. The display panel is the display panel in Embodiment 2, and the array substrate 1 is located between the backlight source 3 and the color filter substrate 2. Here, the backlight source 3 may be the backlight source 3 used in the existing LCD display device, or may be another structure capable of generating uniform light, which is not limited here.

[0079] In this embodiment, the direction of the end of the optical waveguide in the thermo-optical switch is in the same plane as the propagation direction of the light in the backlight, that is, the entire plane formed by the thermo-optical switch and the array substrate is in a vertical relationship.

[0080] The color filter substrate 2 is placed in fro...

Abstract

The invention belongs to the field of display technology, and relates to an array substrate, a display panel and a display device. The array substrate comprises an array substrate, a plurality of pixel cells formed by square crossing of grating lines and data lines, and switch transistors for controlling the pixel cells to switch on and off, wherein a thermo-optic switch is arranged in each pixel cell and comprises a light guiding part with thermal index change and a heating part arranged on each light guiding part; the heating parts are connected with the data lines through the switch transistors; the switch transistors are used for controlling data signals to be output to the heating parts; the heating parts are heated under the action of current of the data signals.

Description

Technical field [0001] The invention belongs to the field of display technology, and specifically relates to an array substrate, a display panel and a display device. Background technique [0002] With the development of display technology, CRT display devices (Cathode Ray Tube, cathode ray tube) have gradually been replaced by liquid crystal display devices (Liquid Crystal Display, LCD for short). Compared with CRT, LCD has obvious improvement in power consumption and volume, and has great advantages in environmental protection. At the same time, LCD has a large visible area and finer picture quality. This is the reason why LCD has replaced CRT as a mainstream display device. . [0003] The current liquid crystal display device includes a backlight source and a display panel, and the display panel includes an array substrate, a color filter substrate, and a liquid crystal layer disposed between the array substrate and the color filter substrate. The electric field is used to con...
