The invention discloses a light receiving sensor, a display panel and electronic equipment. The light receiving sensor comprises a photosensitive element and a pixel driving circuit, wherein the pixel driving circuit comprises a source follower and a frequency increasing sub-circuit, the source follower is connected with the photosensitive element to generate an electric signal according to charges of the photosensitive element, and the frequency increasing sub-circuit is connected with the source follower so as to increase the sampling frequency of the pixel driving circuit. According to the light receiving sensor, the display panel and the electronic equipment, through the design of adding the frequency increasing sub-circuit in the pixel driving circuit of the light receiving sensor, adaptive adjustment of the circuit frequency is realized, the frequency characteristic of the light receiving sensor can be effectively enhanced on the premise of ensuring the area, and the design of high frequency and low bit error rate is realized.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a light-receiving sensor, a display panel and electronic equipment. Background technique [0002] Optical communication technology has developed rapidly in recent years due to its high speed and privacy. Optical communication technology uses the periodic change of light intensity as the information transmission medium, which can realize high-speed and high-precision transmission of information. The core technology of this is to quickly convert the photon flow with signal into an electrical signal. This technology can effectively widen the channel. Transmitting digital information more quickly has high market application value. [0003] At present, there are two core problems to be solved in optical communication technology, one is the strength of the optical signal, and the other is the frequency of the optical signal, which is a pair of contradictions. Although incr...
