Abstract

The invention discloses a pixel circuit, a driving method and a display device, comprising: an input module, a light-emitting control module, a compensation module, a first storage module, a second storage module, a driving transistor and a light-emitting device. Through the mutual cooperation of the above modules and components, the problem of uneven luminous brightness caused by the uneven threshold voltage voltage and the voltage drop of the first power supply terminal is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel circuit, a driving method and a display device. Background technique [0002] The organic light emitting diode (Organic Light Emitting Diode, OLED) panel has the characteristics of bendability, high contrast ratio, low power consumption, etc., and has received extensive attention. Among them, the pixel circuit is the core technical content of the OLED panel, which has important research significance. Generally, the OLED in the OLED panel is driven to emit light by the current generated by the driving transistor in the pixel circuit. However, due to the limitation of the process and the increase of the service time, the threshold voltage Vth of the driving transistor will drift to different degrees, so that the OLED panel will have the problem of uneven luminance of the OLED. Moreover, due to the existence of IRDrop (voltage drop) in the OLED panel, the OLED panel will ...
