Problems solved by technology

[0004] Based on the above structure, since the flexible OLED display will be frequently bent, the light emitted from the organic material functional layer 202 of the sub-pixel will be reflected and refracted in the encapsulation layer 40, thereby causing the light to be transmitted from the adjacent sub-pixel Emitting, resulting in a decrease in color purity and color shift, which in turn affects the display effect

Abstract

The embodiment of the present invention provides a flexible OLED display and a manufacturing method thereof, and relates to the display technology field. Light emitted from sub-pixels is prevented from interfering with adjacent sub-pixels, and thus the color purity is improved and a color case phenomenon is improved. The flexible OLED display includes a flexible substrate, top emission light emitting diodes arranged on the flexible substrate and positioned in sub-pixel areas, a pixel defining layer positioned between every two adjacent top emission light emitting diodes, and a packaging layer. The packaging layer at least includes a first pattern layer. The first pattern layer at least includes first patterns that correspond to the pixel defining layers. Except the positions corresponding to the first patterns, other positions of the packaging layer are all transparent. Provided are the flexible OLED display and preparation thereof.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible OLED display and a preparation method thereof. Background technique [0002] Flexible display technology has developed rapidly in recent years, which has led to great progress in flexible displays from screen size to display quality. Whether it is the cathode ray tube (Cathode Ray Tube, referred to as CRT) that is on the verge of disappearing, or the current mainstream liquid crystal display (Liquid Crystal Display, referred to as LCD), they all belong to traditional rigid displays in essence. Compared with traditional rigid displays, flexible displays have many advantages, such as impact resistance, strong shock resistance, light weight, small size, and more convenient to carry. [0003] Currently, flexible displays are mainly flexible OLED displays. Such as figure 1 As shown, the flexible OLED display includes a flexible substrate 10, an anode 201 disposed at eac...
