Example Embodiment

[0023] The technical solutions in the present application embodiment will be described in conjunction with the drawings in the present application embodiment. Obviously, the described embodiments are merely the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present application, those skilled in the art will belong to the scope of this application without all other embodiments obtained without creative labor.

[0024] like figure 1 or Figure 4 As shown, this embodiment provides a pixel circuit including a driving transistor T1, a write transistor T3, a first capacitor C1, and a second capacitor C2; the driving transistor T1 is connected to the first power signal VDD and the second power signal. The VSS constituted a light-emitting circuit for controlling the current flowing through the illuminating loop; one of the source / drain written to the transistor T3 is connected to the gate of the drive transistor T1, and the source / drai...

Abstract

The invention discloses a pixel circuit and a display panel. The pixel circuit comprises a driving transistor, a writing transistor, a first capacitor and a second capacitor, wherein the ratio of thecapacitance value of the second capacitor to the capacitance value of the first capacitor is not less than 50% and not more than 150%; by configuring the proportional relation between the capacitancevalue of the second capacitor and the capacitance value of the first capacitor, the write-in effect of data signals can be improved; moreover, the voltage range of the data signal is increased, and the gray-scale precision can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of pixel driving technology, and in particular to a pixel circuit and a display panel. Background technique [0002] The current display industry is developing rapidly, and display applications have been integrated into all aspects of people's lives, but product homogeneity is becoming increasingly serious. Consumers are increasingly demanding high-quality displays. High-frequency display has always been sought after by consumers in the high-end display field. In the early days, it mainly focused on professional and game applications. Now the demand for high frequency on mobile phones is also increasing, and high frequency display can bring a smoother user experience. [0003] Among them, the current-driven pixel display represented by tiny LED has higher difficulty in high-frequency driving. In order to ensure the display quality of the current self-illu...
