Problems solved by technology

In order to ensure the use effect of the front camera, the front camera needs to have a certain effective photosensitive area, that is, the lens and the photodiode need to occupy enough area, so that the front camera, as a separate installation component, needs to occupy a movable display There is a lot of space in the device, which limits the thinnest size that the mobile display device can achieve. It does not meet the development trend of light and thin mobile display devices, and it is difficult to meet the needs of users.

Embodiment approach

[0090] In addition, in the above-mentioned embodiment, refer to Figure 12 If the OLED light-emitting functional layer is formed of white light organic light-emitting materials, there is another implementation mode for forming the first electrode layer 3 on the surface of the photodiode 21 away from the base substrate 1, for example: when the photodiode 21 is away from the base substrate 1 A planarization layer 12 is formed on the surface of the planarization layer 12 with a light-transmitting material, and a first electrode layer 3 is formed on the surface of the planarization layer 12 away from the photodiode 21;

[0091] Then the manufacturing method of the display panel also includes:

[0092] Form the third color filter 13 on the surface of the second electrode layer 5 away from the OLED light-emitting functional layer, so that the orthographic projection of the third color filter 13 on the base substrate 1 covers the corresponding white OLED light-emitting functional lay...

Abstract

The invention discloses a display panel, a manufacturing method and a display device, which relate to the field of display technology and are used for reducing the overall thickness of a display device with a front camera. The display panel includes a base substrate and a plurality of sub-pixel units formed on the base substrate, each sub-pixel unit includes an OLED light-emitting module, at least one sub-pixel unit also includes an image photosensitive module, and the image photosensitive module includes an image sensing module for collecting imaging light signals A photodiode, and a lens corresponding to the photodiode; the photodiode is arranged on the base substrate, and the lens is arranged on the first electrode layer of the OLED light-emitting module in the corresponding sub-pixel unit. The display panel, the manufacturing method and the display device provided by the present invention are used for image collection and display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method, and a display device. Background technique [0002] With the rapid development of technology, mobile display devices such as mobile phones and tablet computers are widely used. In order to meet the diverse needs of users such as portability and aesthetics, portable display devices are increasingly pursuing thinner and thinner devices. [0003] At present, most of the movable display devices are equipped with a front camera, and the front camera includes a photosensitive unit and a driving circuit for driving the photosensitive unit, wherein the photosensitive unit includes a lens and a photodiode. In order to ensure the use effect of the front camera, the front camera needs to have a certain effective photosensitive area, that is, the lens and the photodiode need to occupy enough area, so that the front camera, as a separate inst...
