Embodiment Construction

[0026] It can be seen from the background art that there is room for improvement in the performance of the stretchable display screen in the prior art. Specifically, existing stretchable display screens have the problems of uneven display brightness and different degrees of fineness of pictures.

[0027] figure 1 is a schematic diagram of the top view structure of a stretchable display screen before and after stretching, wherein, figure 1 The middle left picture is a schematic diagram before stretching. figure 1 The middle right picture is the schematic diagram after stretching. The analysis found that the causes of the above problems include: Reference figure 1 The stretchable display screen includes a plurality of light-emitting regions 10 and non-light-emitting regions (not marked) between adjacent light-emitting regions 10, wherein the positions of the light-emitting regions 10 are defined by openings in the pixel-defining layer 20; and For all light-emitting regions 1...

Abstract

The embodiment of the invention relates to a pixel limiting structure, an OLED structure, and a display panel. The pixel limiting structure includes a first pixel limiting layer and a second pixel limiting layer; the first pixel limiting layer includes a first pixel limiting portion and a first stretching portion; the second pixel limiting layer includes a second pixel limiting portion and a second stretching portion; the first pixel limiting portion and the second pixel limiting portion together limit a pixel opening; the first stretching portion and the second stretching portion are separately located on two opposite sides of the same pixel opening; and the first pixel limiting portion and the second pixel limiting portion have an overlapping region on the other two opposite sides of thesame pixel opening. The invention can reduce the difference of the luminescence brightness of the OLED structure before and after stretching, and improve the stretching performance and display effectof the OLED structure.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a pixel-defining structure, an OLED structure, and a display panel. Background technique [0002] OLED (Organic Light-Emitting Diode) is called an organic light-emitting diode. OLED display technology has many advantages such as full solid state, active light emission, high contrast, ultra-thin, low power consumption, fast effect speed, wide working range, easy realization of flexible display and 3D display, etc., making it widely used in many display devices at present. , for example on televisions and mobile devices. [0003] Flexible OLED refers to a flexible organic light emitting diode, which is manufactured based on a flexible substrate and operates on the flexible substrate. Compared with traditional rigid OLEDs, flexible OLEDs are more flexible, lighter and thinner, making foldable and rollable display technologies possible. With the in-d...
