Display panel and fingerprint recognition control method of display panel

Abstract

The embodiment of the invention provides a display panel and a fingerprint recognition control method of the display panel. The method is used for realizing a fingerprint recognition function on the display panel, and meanwhile, the aperture rate of the display panel is improved. The display panel provided by the embodiment of the invention comprises a light sensing sensor and a film transistor connected with the light sensing sensor, wherein the light sensing sensor is positioned in a light shielding region of the display panel; and the light shielding region is a region through which light with the specific wavelength can penetrate.

Description

Technical field [0001] The invention relates to the field of liquid crystal display panel systems, and in particular to a display panel and a method for controlling fingerprint identification thereof. Background technique [0002] The earliest recorded human handprints and footprints were about 4000 years ago when the pyramids were built in ancient Egypt. In ancient times, some clay pottery was left with the fingerprints of pottery craftsmen. The Chinese used to put their fingerprints on official documents. Documents with fingerprints from before 300 BC still exist, and this signature method is still used until now. . As early as 1880, the British Henry Forz proposed the use of fingerprint identification system to identify crimes. By the 1970s, due to the widespread application of computers and the development of pattern recognition theory, people had begun to study the use of computers for automatic fingerprint recognition. At present, integrating the fingerprint recognition ...
