Problems solved by technology

[0004] However, due to the high thickness and low light transmittance of the polarizer itself, attaching it to the display panel will not only increase the overall thickness of the display panel, resulting in a decrease in the flexibility of the display panel, but also reduce the light output brightness of the display panel, affecting display effect

Embodiment 1

[0052]figure 1 It is a schematic structural diagram of a flexible display panel provided by Embodiment 1 of the present invention. figure 2 It is a schematic structural diagram of the second light-absorbing layer of the flexible display panel provided by Embodiment 1 of the present invention. image 3 It is a schematic structural diagram of part A of the flexible display panel provided by Embodiment 1 of the present invention.

[0053] The inventors of the present invention found in the actual research process that during the use of the current flexible display panel, when the ambient light intensity is high, the ambient light will be reflected on the surface of the display panel, or be reflected after entering the interior of the display panel, The light emitted by the display panel itself and the reflected light from the environment simultaneously enter the user's field of vision, resulting in a low contrast ratio of the display panel, which seriously affects the display ef...

Embodiment 2

[0077] Figure 4 It is a schematic structural diagram of the second light-absorbing layer of the flexible display panel provided by Embodiment 2 of the present invention. refer to Figure 4 As shown, on the basis of the first embodiment above, the second embodiment of the present invention also provides a flexible display panel with another structure. Compared with the first embodiment, the difference between the second embodiment and the first embodiment is: the flexible display panel The structure of the second light absorbing layer is different.

[0078] Specifically, reflective particles are arranged in the second light absorbing layer 50 .

[0079] It should be noted that, from the description of Embodiment 1, it can be seen that when the surface of the second light-absorbing layer 50 is flat, ambient light is irradiated on the second light-absorbing layer 50, although most of the ambient light is absorbed by it, but a small part of the ambient light Light will still b...

Embodiment 3

[0086] On the basis of the first and second embodiments above, the third embodiment of the present invention further provides a flexible display device, which includes the flexible display panel of the first or second embodiment. The flexible display device provided in this embodiment can be any product or component with a display function, such as a TV, a digital camera, a mobile phone, a tablet computer, a smart watch, an e-book, a navigator, etc. that include a flexible display panel.

[0087] Other technical features are the same as those in Embodiment 1 or Embodiment 2, and can achieve the same technical effect, and will not be repeated here.

[0088] In the flexible display device provided in Embodiment 3 of the present invention, a first light-absorbing layer is provided on the pixel-defining layer of the flexible display panel, and the first light-absorbing layer is used to absorb the ambient light irradiated on the surface of the pixel-defining layer, thereby reducing ...

Abstract

The invention provides a flexible display panel and a flexible display device; the flexible display panel comprises an array substrate and a pixel limiting layer arranged on the array substrate; a plurality of openings are formed in the pixel limiting layer; a light-emitting unit is arranged in each opening; a first light absorption layer is arranged on one surface, deviating from the array substrate, of the pixel limiting layer, and a light extraction layer is arranged on one surface, deviating from the array substrate, of the light-emitting unit; and the flexible display panel further comprises a second light absorption layer which simultaneously covers the first light absorption layer and the light extraction layer. According to the display panel, the reflection light of ambient light on the surface and the interior of the display panel can be weakened, the influence of the reflection light on the light emitting of the display panel is reduced, the display effect of the display panel in a strong light environment is optimized, and meanwhile, the flexibility of the display panel is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel and a flexible display device. Background technique [0002] With the rapid development of electronic technology, people's requirements for the foldable performance of electronic devices such as mobile phones and computers are gradually increasing. Among them, flexible organic light-emitting diodes (Organic Light-Emitting Diode, referred to as: OLED) are widely used in In flexible display devices such as terminal equipment and wearable equipment. [0003] When the current display panel is in use, ambient light will be reflected on the surface or internal film of the display panel, and the reflected light and the light emitted by the display panel will enter the user's sight at the same time, resulting in a decrease in the contrast of the display panel and affecting the display effect. In order to solve this problem, a polarizer is pasted on the...
