The invention discloses a display device, a pixel correction circuit and a pixel correction method. The pixel correction circuit includes: a signal input unit for inputting a first signal and a second signal in a correction mode; a follower, the input terminal of the follower is connected to the The signal input unit is connected, and the follower is used to receive the first signal and the second signal in sequence, and follow the first signal output to output the first follow signal when receiving the first signal, and follow the second signal when receiving the second signal output to output the second following signal; the reading unit, the reading unit is connected to the output end of the follower, the reading unit generates the first reading signal by reading the first following signal, and reads the second following signal to generating a second read signal; the read unit calculates a compensation gain according to the first signal and the second signal and the first read signal and the second read signal, so that the read unit performs compensation correction according to the compensation gain, thereby being able to utilize the correction Solve the problem of poor following effect.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a pixel correction circuit, a display device with the circuit and a pixel correction method. Background technique [0002] The display device in the related art partially uses the follower to output the potential to reduce the interference between pixels, wherein the ideal follower effect of the follower is A V =1, however, due to the non-ideal characteristics of the device, such as insufficient electron mobility, insufficient output impedance, etc., the following effect will be poor, such as A V <1, affects the size of the semaphore. [0003] Therefore, there is a need for improvement in the related art. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a pixel correction circuit, which can solve the problem of p...
