Pixel circuit, driving method thereof and light-emitting device

Abstract

The invention provides a pixel circuit, a driving method thereof and a light-emitting device, relates to the technical field of display, and is used for solving the problem that the light-emitting device cannot completely realize low-gray-scale display. The pixel circuit comprises a driving circuit which comprises a control end, a first end and a second end, and the driving circuit is configured to control a driving signal flowing through the first end and the second end according to a signal of the control end; the data writing circuit is coupled with the first end of the driving circuit and is configured to write a data signal into the driving circuit in response to the first scanning signal; a compensation circuit including a first capacitor coupled between the first node and a control terminal of the driving circuit, and a first switching device coupled between the first node and a second terminal of the driving circuit, the first switching device being configured to write a data signal via the driving circuit to the first node in response to a first scan signal; the initialization circuit is configured to initialize the first node and the control end of the driving circuit in response to a second scanning signal.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel circuit, a driving method thereof, and a light emitting device. Background technique [0002] Light emitting devices (such as LED light emitting devices) are widely used in the field of display, such as self-luminous display devices such as miniLED panels and micro LED panels containing multiple LED lights. [0003] Taking the mini LED panel as a display panel as an example, when the mini LED panel performs low-gray-scale display, it requires a smaller adjustment accuracy of the data voltage to fully realize the low-gray-scale display. The circuit cannot meet the adjustment accuracy of the smaller data voltage required for low grayscale display.
