Sensing assembly and full-screen fingerprint touch display panel

Abstract

The invention provides a sensing assembly, which comprises a display substrate provided with a pixel layer used for displaying images, the pixel layer is provided with a plurality of pixel blocks, andeach pixel block is divided into a color block area, m light transmission areas, n fingerprint sensing areas and k storage circuit areas according to row and column rules; wherein the adjacent areasof the R, G and B color blocks are m light transmission areas, n fingerprint sensing areas or k storage circuit areas according to row rules and column rules, m is equal to 0-2, n is equal to 0-2, k is equal to 0-2, and m, n and k are not 0 at the same time; wherein the storage circuit area comprises a memory device, and the fingerprint sensing area comprises a photosensitive device and is integrated on the display substrate through an in-cell technology. Therefore, high light transmittance, full-screen fingerprint touch or pixel layout of additional memory devices can be effectively achieved.

Description

technical field [0001] The present invention relates to the technical field of a display panel, in particular to a sensing component with high light transmittance and supporting full-screen fingerprint touch and a display panel thereof. Background technique [0002] With the diversity of consumer application needs, based on the improvement of display resolution and technological progress, the design of advanced applications has also developed more flexible space, and further achieved terminal applications that could not be realized in the past. For example: in-screen fingerprint recognition...etc. Fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with the fingerprint recognition function, the user only needs to touch the finge...

AI Technical Summary

Problems solved by technology

In the existing display device with fingerprint identification function, when the light emitted by the fingerprint identification light source is reflected by the finger, it will be irradiated on a plurality of fingerprint identification sensors, so that each fingerprint identification sensor receives the fingerprint signal corresponding to its position, It also receives crosstalk signals from other locations, which affects the accuracy of fingerprint recognition by the fingerprint recognition sensor

[0003] Due to the limitations of the shape and structure of the current fingerprint module in the related art, the fingerprint recognition can only be limited to a fixed area of ​​the mobile phone. The upper surface of the display component can be divided into a transparent window area and a frame area. The transparent window area has a touch function, and The fingerprint module is set in the frame area, so that the fingerprint identification can only be realized by attaching the fingerprint module in the frame area of ​​the mobile phone or the back of the mobile phone case; therefore, the fingerprint identification function is limited in the frame area, and the in-plane transparent window area cannot be realized. The fingerprint recognition function also makes the frame of the display component larger, which cannot effectively increase the screen-to-body ratio

Furthermore, if figure 1 , the current practice is that the sub-pixels (R color block, G color block, B color block) are arranged side by side to form a single pixel. This method has low transparency of the display screen and relatively inflexible design and application space
