Problems solved by technology

However, the current scanning circuit is very simplified, and it will be more and more difficult to simplify it. It is difficult to make further progress in realizing narrow borders with simple circuits: the design work is related to process equipment, requiring more expensive equipment and more Fine process capability, so it is difficult to further implement with stricter design rules

Embodiment 1

[0037] This embodiment provides an array substrate in which the light-emitting unit extends to the GOA area, so that the light-emitting unit and the driving signal unit at least partially overlap in the orthographic projection direction, which can conveniently realize a narrow frame structure in an OLED display panel.

[0038] like image 3 As shown, the array substrate includes a light-emitting unit 1, a driving unit 2 for driving the light-emitting unit 1, and a driving signal unit 3 for providing driving signals for the driving unit 2 (ie, a driving circuit located in the lead wiring area). The driving unit 2 The drive signal unit 3 is arranged in the center area of ​​the array substrate, and the drive signal unit 3 is arranged in the edge area, and the edge area surrounds the center area. The light-emitting unit 1 is disposed above the driving unit 2 and at least partially extends to the edge area corresponding to the driving signal unit 3 . image 3 In the array substrat...

Embodiment 2

[0050] This embodiment provides a display panel including the array substrate in Embodiment 1.

[0051] On the basis of the array substrate of Example 1, a package substrate is formed above it, and a necessary driving circuit structure is formed in the edge area (for example, for the driving circuit for providing pixel data for display, mainly for data line driving), so as to form a display panel.

[0052] Based on the structure of the above array substrate, on the basis of the same outer frame size, the display panel can provide a larger effective display area and a narrower frame width, and the assembly is lighter, thinner and simpler.

Embodiment 3

[0054] This embodiment provides a display device, including the display panel in the second embodiment.

[0055] The display device can be any product or component with display function, such as electronic paper, OLED panel, mobile phone, tablet computer, TV, monitor, notebook computer, digital photo frame, and navigator.

[0056] The display device is based on the above-mentioned mechanism of the display panel, and can provide the audience with a better visual experience.

Abstract

The invention belongs to the field of display technology, and in particular relates to an array substrate, a display panel and a display device. The array substrate includes a light emitting unit, a driving unit for driving the light emitting unit, and a driving signal unit for providing a driving signal to the driving unit, the driving unit is arranged in the central area of ​​the array substrate, the The driving signal unit is disposed in an edge area surrounding the central area, the light emitting unit is disposed on the driving unit, and the light emitting unit at least partially extends to the edge area corresponding to the driving signal unit. The array substrate can achieve the purpose of reducing the frame width while enlarging the display area, and also has the effect of increasing the pixel aperture ratio.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate, a display panel and a display device. Background technique [0002] The development direction of display technology is aimed at improving the user's experience, including improving the display characteristics such as color gamut, resolution PPI, and contrast ratio. The application of the narrow border is a way to improve the user's experience without improving the display effect of the display device itself. The advantage of narrow-frame display is that the ratio of the display area to the non-display area is larger, which makes the display area look larger, thereby improving the user's experience; The width of the seam at the splicing point is reduced, and the overall display effect of the display device is improved. With the popularization of consumer display device products such as mobile phones and TVs, higher requirements are gradually put ...
