Problems solved by technology

However, the structures of the existing flexible OLED display panels and flexible OLED display devices cannot well avoid laser irradiation to these structures that need to avoid laser light, resulting in the need to avoid laser light in the production process of flexible OLED display panels and flexible OLED display devices. The structure is irradiated by laser, which destroys the performance of these structures, resulting in a decrease in the display performance of flexible OLED display panels and flexible OLED display devices

Embodiment Construction

[0027] A cross-sectional schematic diagram of an existing flexible OLED display panel as shown in figure 1 As shown, the flexible OLED display panel includes a flexible substrate 100 , a buffer layer 110 and a pixel unit 120 . The buffer layer 110 is also partly located directly on the surface of the flexible substrate 100 . The pixel unit 120 is located on the surface of the buffer layer 110 , and the buffer layer 110 is located between the flexible substrate 100 and the pixel unit 120 . The buffer layer 110 is provided to ensure that structures such as the pixel unit 120 are isolated from water and oxygen, and to balance the stress of the flexible substrate.

[0028] figure 1 During the manufacturing process of the flexible OLED display panel shown, a laser needs to be used to separate the flexible substrate 100 from the corresponding carrier substrate (not shown), and the pixel unit 120 has a structure that needs to be protected from being irradiated by the laser. Howeve...

Abstract

The invention discloses a flexile OLED display panel and a flexible OLED display apparatus. The flexile OLED display panel comprises a flexible substrate, a pixel unit, a buffer layer and a shading layer, wherein the flexible substrate has a first surface; the buffer layer is positioned on the first surface of the flexible substrate, and the buffer layer is positioned between the flexible substrate and the pixel unit; and the shading layer is positioned in the buffer layer. The performance of the flexile OLED display panel is improved.

Description

technical field [0001] The invention relates to the field of photoelectric display, in particular to a flexible OLED display panel and a flexible OLED display device. Background technique [0002] Organic light-emitting diodes (OLED) display panels have the advantages of self-illumination, high contrast, thin thickness, wide viewing angle, and fast response speed. The flexible OLED display panel is one of the important development trends. [0003] Flexible OLED display panels can not only be thinner and thinner in size, but also reduce power consumption, thereby helping to improve the battery life of corresponding products. At the same time, due to the bendability and flexibility of the flexible OLED display panel, its durability is also higher than that of ordinary hard display panels. Flexible OLED display panels can be widely used in various products with display functions, such as tablet computers, TVs, mobile terminals and various wearable devices. [0004] Existing ...
