Problems solved by technology

[0002] In related technologies, the requirements for the screen-to-body ratio of consumer electronics such as mobile phones are getting higher and higher, and the water drop screen and notch screen are not high in aesthetics, so full-screen display can be realized The under-screen camera technology needs to be developed urgently
The general method is to set a display area on the display panel that can be used for displaying and capturing images at the same time. However, the brightness of this display area is lower than other display areas on the display panel, resulting in uneven display and mura feeling.

Embodiment Construction

[0032] The exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. Rather, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0033] In the related art, the organic light emitting display device has low contrast and outdoor visibility of the screen due to the reflection of the external ambient light by the cathode metal. The general solution is to attach a circular polarizer to reduce reflectivity. However, due to the high cost of the polarizer and low transmittance, the screen has high power consumption...

Abstract

The invention relates to a display panel and a display device. The display panel comprises a first display area and a second display area. The display panel comprises a substrate, a first pixel unit,a second pixel unit, a packaging layer, a black matrix layer and a filter layer. The first pixel unit and the second pixel unit are located on the substrate, the first pixel unit is located in the first display area, and the second pixel unit is located in the second display area. The first pixel unit comprises a first sub-pixel, and the second pixel unit comprises a second sub-pixel and a light-transmitting part. The packaging layer is located on the first pixel unit and the second pixel unit. The black matrix layer is located on the packaging layer. The filter layer is located on the black matrix layer and comprises a first filter sub-layer and a second filter sub-layer, the first filter sub-layer is located on the first sub-pixel, the second filter sub-layer is located on the second sub-pixel, the thickness of the second filter sub-layer is smaller than that of the first filter sub-layer, and the filter layer does not cover the light-transmitting part. According to the embodiment ofthe invention, uniform display is facilitated, and the mura feeling of display can be weakened.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device. Background technique [0002] In related technologies, the requirements for the screen-to-body ratio of consumer electronics such as mobile phones are getting higher and higher, and the water drop screen and the notch screen are not very beautiful. Therefore, the under-screen camera technology that can achieve full-screen display is in urgent need of development. The general practice is to set a display area on the display panel that can be used to display and collect images at the same time. However, the brightness of the display area is lower than other display areas on the display panel, resulting in uneven display and a sense of mura. Summary of the invention [0003] The present invention provides a display panel and a display device to solve the deficiencies in related technologies. [0004] According to a first aspect of the embo...
