Problems solved by technology

The vapor deposition method is easy to realize the production of small-sized high-resolution products, but the material utilization rate is low; the material utilization rate of inkjet printing is high, and it is easy to realize large-scale products
[0003] However, inkjet printing still has technical problems that have not yet been well resolved: because the ink droplets ejected from the nozzle are relatively large, and the pixel pits are usually small, it is difficult for the ink droplets to fall into the pixel pits accurately, especially for the pixel pits in the standard RGB arrangement. In this way, the resolution of the final display panel product is low

Embodiment 1

[0029] The array substrate provided by the embodiment of the present invention includes:

[0030] Substrate (not shown in the figure);

[0031] The pixel defining layer formed on the substrate, the pixel defining layer includes a plate body 400, the surface of the plate body 400 facing away from the substrate is the first surface, and the surface of the plate body 400 facing the substrate is the second surface, the plate body 400 has an opening A plurality of channels 100 located on the first surface, a plurality of pixel pits 200 are formed at the bottom of each channel 100; each channel 100 has opposite first sidewalls and second sidewalls, and the first sidewall is provided with a plurality of The opening faces the first recess 310 of the second side wall, and the second side wall is provided with a second recess 320 corresponding to the first recess 310 and opening toward the first side wall, each pair of first recesses 310 corresponding to each other It is arranged oppos...

Embodiment 2

[0054] The display panel provided by the embodiment of the present invention includes: the array substrate provided by the first embodiment.

[0055] The display panel includes the array substrate provided in Embodiment 1, the array substrate includes a pixel defining layer formed on the substrate, the pixel defining layer includes a board body 400, and the board body 400 has a plurality of channels 100 with openings located on the first surface, each A plurality of pixel pits 200 are formed at the bottom of the channel 100, and the first depression 310 on the first side wall of the channel 100 and the second depression 320 on the second side wall of the channel 100 form the craters 300 in one-to-one correspondence; inkjet printing is performed on the array substrate At this time, the print nozzle is aimed at the crater 300 to drop ink, and the ink enters the channel 100 from the crater 300, and flows to each pixel hole 200 along the channel 100 to complete the printing of each...

Embodiment 3

[0057] The display device provided by the embodiment of the present invention includes: the display panel provided by the third embodiment.

[0058] The array substrate in the display device includes a pixel defining layer formed on the substrate. The pixel defining layer includes a plate body 400. The plate body 400 has a plurality of channels 100 with openings located on the first surface. A plurality of channels 100 are formed at the bottom of each channel 100. The pixel crater 200, the first depression 310 on the first side wall of the channel 100, and the second depression 320 on the second side wall form the bullet crater 300 in one-to-one correspondence; when inkjet printing is performed on the array substrate, the print head is aligned with the There are 300 drops of ink in the crater, and the ink enters the channel 100 by the crater 300, and flows to each pixel crater 200 along the channel 100, so as to complete the printing of each pixel; Compared with directly dropp...

Abstract

The invention relates to the technical field of display, and discloses an array substrate, a display panel and a display device. A pixel bounding layer formed on the substrate, the pixel bounding layer comprising a plate body, a surface of the plate body facing away from the substrate being a first surface and a surface of the plate body facing the substrate being a second surface, the plate bodyhaving a plurality of channels with openings located on the first surface, and a plurality of pixel pits formed at the bottom of each channel; Each channel has an opposite first sidewall and a secondsidewall, and the first sidewall is provided with a plurality of first depressions opening toward the second sidewall, the second sidewall is provided with second depressions corresponding to the first depressions one by one and opening toward the first sidewall, and each pair of first depressions and second depressions corresponding to each other are oppositely disposed to cooperate to form an impact crater. The array substrate can be used for reducing the difficulty of pixel inkjet printing in the manufacturing process of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] At present, in OLED (Chinese name: Organic Light-Emitting Diode; English full name: Organic Light-Emitting Diode) display technology, there are two ways to make pixels: evaporation and inkjet printing. The vapor deposition method is easy to realize the production of small-sized high-resolution products, but the material utilization rate is low; the material utilization rate of inkjet printing is high, and it is easy to realize large-scale products. [0003] However, inkjet printing still has technical problems that have not yet been well resolved: because the ink droplets ejected by the nozzle are relatively large, and the pixel pits are usually small, it is difficult for the ink droplets to fall into the pixel pits accurately, especially for the pixel pits in the standard RGB arrange...
