Abstract

The invention relates to a pixel circuit, a display panel and a display device. The pixel circuit comprises a light emitting module, an anode initialization module, a data writing module, a driving module and an adjusting module. The anode initialization module is connected with the anode of the light-emitting module and is used for writing a reference voltage signal into the light-emitting module; the light emitting module is used for forming an anode initial voltage according to the reference voltage signal; the data writing module is connected with the driving module and is used for writing a data signal into the driving module; the driving module is connected with the anode of the light-emitting module and is used for driving the light-emitting module to emit light according to the data signal; and the adjusting module is connected with the anode of the light-emitting module and is used for adjusting the initial voltage of the anode according to an adjusting signal, so that the charging time of the light-emitting module is within a preset range. The pixel circuit can improve the problem of low-gray-scale color cast.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a pixel circuit, a display panel and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display devices have many advantages such as self-luminescence, low driving voltage, high luminous efficiency, short response time, clarity and contrast. With the development of display technology, there are more and more fields of OLED application, and the requirements are getting higher and higher. The OLED display device needs to be compatible with various frequencies, but frequency switching will cause the problem of low grayscale color shift. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a pixel circuit, a display panel and a display device. [0004] In a first aspect, a pixel circuit is provided, including a light-emitting module, an anode initialization module, a data writing m...
