Embodiment 1
[0040] An array substrate, such as figure 1 As shown, it includes a plurality of pixel units 16 formed by the vertical crossing of gate lines 13 and data lines 14 on the base substrate (not shown in the figure), and each pixel unit 16 includes a light-switching function to control the pixel to be turned on and off. The switch transistor 11 also includes a thermo-optical switch 12 with a thermo-induced refractive index change;
[0041] It should be noted, figure 1 It is only schematically illustrated that the pixel unit includes a thermo-optic switch, and does not illustrate the relative size of the thermo-optic switch and the pixel unit.
[0042] For a clearer description, the setting method of thermo-optic switching in each pixel unit, such as Figure 8 As shown, it is a partially enlarged schematic diagram of a pixel unit. In an actual application scenario, the thermo-optic switch 12 is arranged in the pixel unit and occupies almost the entire pixel unit, so as to ensure t...
Embodiment 2
[0070] This embodiment provides a display panel. In the display panel, the array substrate cooperates with the color filter substrate to realize the display of different color gray scales.
[0071] Optionally, the thermo-optic switch in each pixel unit covers the entire area of the pixel unit to avoid light leakage.
[0072] The color filter substrate can be a commonly used color filter substrate, and a black matrix can be set on the color filter substrate to further avoid light leakage.
[0073] The display panel includes an array substrate and a color filter substrate. The array substrate adopts the above-mentioned array substrate, and the array substrate and the color filter substrate are combined to form. The array substrate is composed of M×N pixel units.
[0074]In this embodiment, the array substrate corresponds to the pixel units of the color filter substrate one by one, and each pixel unit is provided with a pixel unit; the red, green and blue pixel units in the col...
Embodiment 3
[0078] This embodiment provides a display device, which can realize a flat panel display effect similar to that of a liquid crystal display device, and has high brightness and good contrast.
[0079] like Figure 7 As shown, a display device includes a backlight 3 and a display panel. The display panel is the display panel in Embodiment 2, wherein the array substrate 1 is located between the backlight 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 other structures capable of generating uniform light, which is not limited here.
[0080] In this embodiment, the direction of the end of the optical waveguide in the thermo-optic switch is in the same plane as the light propagation direction in the backlight, that is, the entire plane formed by the thermo-optic switch and the array substrate is perpendicular to each other.
[0081] The color filter substrate 2 is placed in front of t...
