Problems solved by technology

[0005] In another way, the fingerprint identification module is arranged on the back of the display device (that is, the side opposite to the display screen), which will increase the thickness of the display device, which is not conducive to the thinning and thinning of the display device, and reduces the user's convenience. Experience
[0006] Moreover, in the above two methods, an additional fingerprint chip needs to be installed in the display device to process the signal of the fingerprint identification module, which further increases the cost of the display device.

Abstract

The invention, which belongs to the technical field of displaying, discloses a display panel and a display device. The display panel comprises a display region including a plurality of grid lines, a plurality of data lines, a plurality of pixels, and a plurality of light sensing elements; the pixels include at least three sub pixels; and the grid lines and the data lines are intersected and insulated to limit sub pixel regions and the sub pixels are arranged in the sub pixel regions. The multiple pixels include fingerprint pixels including the light sensing elements; and the light sensing elements are at least located in two sub pixel regions. Compared with the prior art, the display panel has the following advantages: no fingerprint recognition module needs to be set additionally, so thatthe screen ratio is increased and the display effect of the full screen is realized; the light sensing elements are at least located in two sub pixel regions and thus can be large, so that light sensed by the light sensing elements is increased and thus the signal quantity of the light sensing elements is improved, the accuracy of fingerprint recognition is enhanced, and reduction of the displayquality of the display panel is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] In a display device provided in the prior art, a fingerprint recognition function is integrated. When using the display device, the user can use the fingerprint identification function to make the display device perform a specific function. The fingerprint identification function is convenient, fast, and highly secure, and is one of the important research and development directions of the display device. [0003] In the prior art, two ways of setting the fingerprint identification module are provided. [0004] In one way, the fingerprint recognition module is placed under the display screen, which will occupy more space on the display device, which is not conducive to improving the screen ratio and the display effect of the full screen. [0005] In another way, the fingerprint identification ...
