Abstract

The invention discloses a display device, a pixel circuit, a compensation method and a compensation device. The pixel circuit comprises drive transistors, data lines and detection signal lines. The method includes the steps: externally compensating the pixel circuit to acquire threshold voltage of the drive transistors; internally compensating the pixel circuit according to the threshold voltage of the drive transistors. Therefore, the threshold voltage of the drive transistors can be compensated, large characteristic change of the drive transistors can be covered, the characteristic change ofthe drive transistors are compensated in real time, compensation hysteresis is effectively avoided, marks and the like generated by external compensation can be eliminated, and display effects are better.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a compensation method for a pixel circuit, a compensation device for a pixel circuit, a pixel circuit and a display device. Background technique [0002] With the advancement of time, AMOLED (Active Matrix Organic Light Emitting Diode, active matrix organic light emitting diode) products are more and more widely used, with its advantages of high contrast, high color gamut, light and thin, and can be made into flexible screens. , is increasingly recognized by people. [0003] With the widespread use of AMOLED products, some problems in the display process need to be properly resolved. For example, due to reasons such as technology, materials, and design, the threshold voltage of the drive transistor in the AMOLED product drifts, which in turn leads to uneven display and poor display effect. Contents of the invention [0004] The present invention aims to solve one of the tech...
