Embodiment 1

[0041] see figure 1 , a display panel provided by an embodiment of the present invention, the display panel includes a photosensitive sensor 21, and a thin film transistor 22 connected to the photosensitive sensor 21, wherein the photosensitive sensor 21 is located in a light-shielding area 23 of the display panel, and the light-shielding area 23 can be An area that transmits light of a specific wavelength.

[0042] Through the display panel provided by the embodiment of the present invention, the photosensitive sensor with fingerprint identification function is arranged in the light-shielding area of ​​the display panel, and the light-shielding area is an area that can transmit light of a specific wavelength, so that light of a specific wavelength is irradiated to the photosensitive sensor. After the sensor, the fingerprint information is determined through the detection principle of the photosensitive sensor, thereby realizing the fingerprint recognition function. At the sa...

Abstract

Embodiments of the present invention provide a display panel and a fingerprint identification control method thereof, which are used to increase the aperture ratio of the display panel while realizing the fingerprint identification function of the display panel. A display panel provided by an embodiment of the present invention includes a photosensitive sensor and a thin film transistor connected to the photosensitive sensor, wherein the photosensitive sensor is located in a light-shielding area of ​​the display panel, and the light-shielding area is capable of transmitting certain The region of wavelengths of light.

Description

technical field [0001] The invention relates to the field of liquid crystal display panel systems, in particular to a display panel and a control method for fingerprint identification thereof. Background technique [0002] The earliest recorded human handprints and footprints date back to about 4,000 years ago when the pyramids were built in ancient Egypt. In ancient times, some clay pottery had the fingerprints of the potters. The Chinese once pressed their own fingerprints on official documents. Documents with fingerprints from 300 BC still exist, and this signature method is still used until now. . As early as 1880, the British Henry Fawds proposed the use of fingerprint identification system to identify crimes. By the 1970s, due to the wide application of computers and the development of pattern recognition theory, people have begun to study the automatic identification of fingerprints using computers. At present, integrating the fingerprint recognition function and t...
