Embodiment 1

[0028] like image 3 and Figure 4 As shown, this embodiment provides an array substrate, including a plurality of sub-pixel units, and a light forming unit corresponding to each of the sub-pixel units for forming light of different colors is provided on the light-emitting surface side of the array substrate.

[0029] When the array substrate 1 and a color filter substrate 2 of this embodiment are used in a display device, each sub-pixel unit on the array substrate corresponds to a color filter on the color filter substrate, and each sub-pixel unit A pixel unit and its corresponding color filter form a sub-pixel. At this time, taking the backlight of the display device as an example that emits white light, the color filter substrate includes a red filter, a green filter, and a blue filter. The sub-pixel unit corresponding to the upper red filter is turned on, and the white light emitted by the backlight passes through the light forming unit corresponding to the sub-pixel uni...

Embodiment 2

[0039] This embodiment provides a method for preparing an array substrate. The array substrate may be the array substrate 1 described in Embodiment 1. The array substrate 1 includes a plurality of sub-pixel units. The method for preparing the array substrate includes:

[0040] Light forming units for forming light of different colors corresponding to each of the sub-pixel units are formed on the light emitting surface of the array substrate 1 .

[0041] Preferably, the light forming unit includes: a red light forming unit, a green light forming unit, and a blue light forming unit, such as image 3 , 4 As shown, further preferably, the red light forming unit is a first quantum dot layer 13 composed of first quantum dots that can excite red light; the green light forming unit is a second quantum dot layer 13 that can excite green light. A second quantum dot layer 14 composed of quantum dots; the blue light forming unit is a third quantum dot layer 15 composed of third quantum d...

Embodiment 3

[0048] This embodiment provides a display device, which includes the array substrate 1 described in Embodiment 1, and a color filter substrate that is boxed with the array substrate, and the color filter substrate includes a plurality of color filters of different colors. A light sheet, wherein the color filters correspond to the sub-pixel units one by one, and the color of the light formed by the color filter corresponding to the sub-pixel units is the same as that of the light formed by the light forming unit.

[0049] The display device in this embodiment may also be any product or component with a display function such as a liquid crystal panel, electronic paper, liquid crystal TV, liquid crystal display, digital photo frame, mobile phone, and tablet computer.

[0050] The display device of this embodiment includes the array substrate described in Embodiment 1, so its display quality is higher.

Abstract

The invention provides an array substrate, a preparation method for the same, and a display device, which belong to the technical field of display, and can solve the problems of lowering of a display quality and influence on normal watching due to an alignment shift caused during box folding, of the existing thin-film transistor liquid crystal displays. The array substrate provided by the invention comprises a plurality of sub-pixel units, wherein light formation units corresponding to the sub-pixel units and used for forming lights with different colours are arranged at the light-emitting light side of the array substrate. The array substrate provided by the invention is capable of improving the display quality of the display device in case of being applied to the display device.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate, a preparation method thereof, and a display device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the advantages of small size, low power consumption, no radiation, high resolution, etc., occupies a dominant position in the current display field, and has been widely used in various In a modern digital information equipment. [0003] TFT liquid crystal displays generally include two parts: a backlight module and a liquid crystal display panel. The liquid crystal display panel includes an array substrate, a color filter substrate, and a liquid crystal layer arranged between the array substrate and the color filter substrate. When making a thin film transistor liquid crystal display, it is necessary to precisely align the color filter substrate and the array substrate to form a liquid crystal cell...
