AI Technical Summary

Technical Problem

When OLED display devices realize extremely narrow frame design, infrared light transmittance is greatly affected by the trace density of the backboard circuit, making it difficult to meet the needs of infrared detection functions.

Method used

In the display area of ​​the display panel, the number of pixel driving circuits is set to be more than the second area within the same area, and a photosensitive device is provided in the second area to ensure that the pixel driving circuit and the photosensitive device are not projected. The overlapping further increases the transmittance of the second region to place the photosensitive device on the back of the display panel.

Benefits of technology

By reducing the area occupied by the pixel driving circuit in the second area, improving the transmittance, canceling the frame space, achieving an extremely narrow frame design, and enhancing the transmittance of infrared light to meet the infrared detection function.

Abstract

The present invention provides a display panel and a display device, wherein the display panel includes a display area, the display area is divided into a first area and a second area, the first area and the second area both have a plurality of pixel units, the pixel units include a light-emitting device and a pixel driving circuit for driving the light-emitting device to emit light; wherein in the first area and the second area of ​​the same area, the number of pixel driving circuits in the first area is greater than the number of pixel driving circuits in the second area. Since in the first area and the second area of ​​the same area, the number of pixel driving circuits in the first area is greater than the number of pixel driving circuits in the second area, the area occupied by the pixel driving circuits in the second area is reduced, and the transmittance of the second area can be improved, so that the photosensitive device can be set on the back of the display panel corresponding to the second area, eliminating the frame space originally occupied by the photosensitive device, expanding the screen ratio of the display screen, and achieving an extremely narrow frame.
