Embodiment 1

[0033] This embodiment provides a display substrate, such as figure 1 As shown, it includes: a base structure 1 and a display structure 2 arranged above the base structure 1. The display substrate also includes a driving circuit 3 for driving the display structure 2 to display. The driving circuit 3 includes a TFT circuit 31 and a peripheral circuit 32. The TFT circuit 31 is arranged between the base structure 1 and the display structure 2, the peripheral circuit 32 is used to drive the TFT circuit 31, the peripheral circuit 32 is arranged on the side of the base structure 1 away from the display structure 2, and the peripheral circuit 32 is located on the base of the display structure 2 In the orthographic projection area on the structure 1 , the peripheral circuit 32 is connected to the TFT circuit 31 through the via hole 11 opened in the base structure 1 .

[0034] Wherein, the peripheral circuit 32 refers to the part of the driving circuit used to drive the TFT circuit, an...

Embodiment 2

[0057] This embodiment provides a display substrate. The difference from Embodiment 1 is that the display structure includes a plurality of liquid crystal pixel units. That is, the display substrate is a liquid crystal display substrate.

[0058] Wherein, a plurality of liquid crystal pixel units are arranged in an array. The specific structure of the liquid crystal display structure is an existing relatively mature technology, and will not be repeated here.

[0059] Other structures and preparation methods of the display substrate in this embodiment are the same as those in Embodiment 1, and details are not repeated here.

[0060] Beneficial effects of embodiment 1-2: the display substrate provided by embodiment 1-2, by arranging the peripheral circuit originally arranged in the frame area of ​​the display substrate in the driving circuit on the side of the base structure away from the display structure, and making it Located in the area of ​​the orthographic projection of ...

Embodiment 3

[0062] This embodiment provides a display device, including the display substrate in Embodiment 1 or 2.

[0063] By using the display substrate in Embodiment 1 or 2, the display device can realize borderless display, which is beneficial to realize the seamless splicing display of the display device.

[0064] The display device provided by the present invention can be any product or component with display function such as LCD panel, LCD TV, OLED panel, OLED TV, display, mobile phone, navigator, etc., and can also be a semi-finished product of the above-mentioned product or component with display function pieces.

Abstract

The invention provides a display substrate, a preparation method thereof and a display device. The display substrate comprises a substrate structure and a display structure arranged on the substrate structure; the display substrate also comprises a driving circuit used for driving display of the display structure; and the driving circuit comprises a TFT circuit and a peripheral circuit, wherein the TFT circuit is arranged between the substrate structure and the display structure, the peripheral circuit is used for driving the TFT circuit, the peripheral circuit is arranged at the side, away from the display structure, of the substrate structure, the peripheral circuit is located in an orthographic projection region, on the substrate structure, of the display structure, and the peripheral circuit is connected with the TFT circuit through a via hole formed in the substrate structure. The display substrate can realize border-free display, and therefore seamless splicing display of the display substrate is benefited.

Description

technical field [0001] The present invention relates to the technical field of head motion detection, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] With the development of display technology, full-screen technology has gradually become the mainstream technology of mobile phones and other handheld devices. At present, GOA (Gate Driver On Array) technology is mainly used to realize the narrowing of left and right borders, and COF (Chip On Film) technology is used to realize the The narrowing of the frame, although the frame of the display screen is becoming narrower and narrower, it is still not possible to realize a display screen without a frame. In order to realize the seamless display of large-size splicing displays, the realization of a truly borderless display is imminent. Contents of the invention [0003] The present invention aims at the above-mentioned technical problems existing in the prio...
