Abstract

The embodiment of the invention provides a display panel, a display device and a control method of the display device, relates to the technical field of display, and can solve the problem that acquired compensation parameters of a driving transistor are inaccurate. In the display panel, at least part of the pixel driving circuit further comprises a detection transistor; the grid electrode of the detection transistor is connected with the second scanning end, the first electrode of the detection transistor is connected with the first electrode of the driving transistor, and the second electrodeof the detection transistor is connected with the detection signal line; the display panel further comprises a detection reference signal line parallel to the detection signal line. An analog-to-digital conversion sub-circuit in the source drive circuit is configured to obtain a first digital signal according to a difference value of voltages input by two input ends and output the first digital signal to the time sequence control circuit, wherein the first digital signal corresponds to a compensation parameter of the driving transistor; the time sequence control circuit is configured to acquire compensation pixel data of the sub-pixel according to the first digital signal and the initial pixel data corresponding to the same sub-pixel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a control method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) displays have the advantages of self-illumination, thinness, low power consumption, high contrast, high color gamut, and flexible display. Among them, AMOLED (Active-matrix OLED, Chinese full name: Active Matrix Organic Light-Emitting Diode) has been widely used in electronics including computers and mobile phones due to its advantages of fast response time, high luminous efficiency, high brightness, and wide viewing angle. products, including various electronic devices. [0003] Due to the influence of process conditions, driving environment and other factors, the threshold voltage and mobility of the driving transistors in each sub-pixel in the OLED display are not the same, so that the driving transistors in each sub-pixel are driven by th...
