AI Technical Summary

Technical Problem

Existing display panels are difficult to switch between different usage states and display modes, cannot simultaneously meet the needs of sharing mode and privacy mode, and the switching operation is complicated.

Method used

Design a display panel that employs a first light-emitting unit and a second light-emitting unit with different extension directions. By controlling their illumination or extinguishing, different states and modes can be switched. The panel includes pixel units arranged in an array on a substrate. The light angle difference between different light-emitting units can be used to switch between sharing and privacy modes.

Benefits of technology

It enables the display panel to switch between multiple usage states and display modes under different conditions, simplifies operation, meets display needs under different viewing angles, and improves the consistency of display effect and brightness uniformity.

Abstract

This invention provides a display panel and its manufacturing method, as well as a display device, for achieving privacy protection under different usage conditions and ensuring consistent privacy protection effects across these conditions. The display panel includes: a substrate; a plurality of pixel units located on one side of the substrate, the pixel units being arranged in an array along a first direction and a second direction, the first and second directions intersecting; each pixel unit includes a plurality of pixel groups; at least one pixel group includes at least one first light-emitting unit and at least one second light-emitting unit arranged along the first direction; the first and second light-emitting units in the same pixel group emit the same light color; the length of the first light-emitting unit in the first direction is L1, and the length of the second light-emitting unit in the first direction is L2, wherein L1 > L2; the length of the first light-emitting unit in the second direction is H1, and the length of the second light-emitting unit in the second direction is H2, wherein H1 < H2, and H1 < L1, H2 > L2.
