The pixel circuit comprises a write-in module, a transfer module, a first time-sharing transmission module, a driving module, a second time-sharing transmission module and a storage module, the storage module and the transfer module can be charged at the same time through data signals, and the transfer module can charge the storage module again through the first time-sharing transmission module, the driving module and the second time-sharing transmission module in the light emitting stage.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a pixel circuit and a display panel. Background technique [0002] The gate of the driving transistor in the pixel circuit of the traditional technical solution generally has the problem of leakage current, which makes it difficult to maintain the gate potential of the driving transistor, for example, as figure 1 The working process of the 7T1C pixel circuit shown can be divided into figure 2 The three main stages of operation are shown: [0003] The first stage S1: the N-1th scan signal SCAN(N-1) is set to low level, the transistor T4 is turned on, and the gate potential of the driving transistor T1 is reset to the potential of the initial signal VI. [0004] The second stage S2: the N-th level scanning signal SCAN(N) is set to low level, the transistor T2 and transistor T3 are turned on, and the data signal DATA charges the gate potential of the drive transistor T...

AI Technical Summary

Problems solved by technology

[0007] In the third stage S3, the luminous brightness of the pixel is directly determined by the gate potential of the drive transistor T1, and in the light-emitting stage T, the most important factor affecting the gate potential of the drive transistor T1 is the leakage current, which will directly affect the light-emitting stage Brightness stability of T
