The invention provides a pixel compensating circuit, a pixel compensating method and a display device. The pixel compensating circuit is characterized in that the control end of a first switch is connected with the first end of a second switch, the first end of the first switch is connected with a first power supply, and the second end of the first switch is connected with the first end of a light-emitting assembly; the control end of the second switch is connected with a second scanning signal end, and the second end of the second switch is connected with a reset signal end; the control end of a third switch is connected with a first scanning signal end, the first end of the third switch is connected with the control end of the first switch, and the second end of the third switch is connected with the second end of the first switch; the first end of a first capacitor is connected with a second power supply, and the second end of the first capacitor is connected with the control end ofthe first switch; the first end of a second capacitor is connected with the second end of the first switch, and the second end of the second capacitor is connected with a data signal end; the secondend of the light-emitting assembly is connected with a third power supply. Due to the implementation of the technical scheme, the problem that the current flowing through the light-emitting assembly is instable due to drift of threshold voltage of the pixel compensating circuit is avoided, and the display uniformity is improved.
Description
technical field [0001] The invention relates to the field of organic light emitting diode display, in particular to a pixel compensation circuit, a pixel compensation method and a display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, abbreviated as OLED) displays can be divided into passive matrix driven organic light emitting diode (abbreviated as PMOLED) display and active matrix driven organic light emitting diode (Active Matrix OLED, abbreviated as AMOLED) display. Among them, the PMOLED display does not emit light when data is not written, but emits light during data writing. This driving method has a simple structure, low cost, and easy design, and is mainly suitable for small and medium-sized displays. AMOLED display, each pixel of the pixel array has a capacitor to store data, so that each pixel can maintain a light-emitting state, because the power consumption of AMOLED display is significantly smaller than that o...
