Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0046] figure 1 It is a partial structural schematic diagram of an existing pixel circuit. Such as figure 1 As shown, the pixel circuit includes a driving transistor DTFT, a switching transistor STFT and a light emitting diode D1. In the initialization phase, the switching transistor STFT is turned on, and the initialization voltage VREFN is transmitted to the anode of the light emitting diode D1 to initialize the light emitting diode D1. In the light emitting stage, the driving transistor DTFT forms a driving ...

Abstract

The invention discloses a driving method and device of a display panel. The display panel includes a pixel circuit, and the method includes: setting a first initialization voltage according to a display brightness value; providing the first initialization voltage to the pixel circuit to initialize a light-emitting module in the pixel circuit. By setting the first initialization voltage according to the display luminance value, when the display luminance value is relatively low, the first initialization voltage is set to be relatively large, and the driving current can be reduced by providing the initialization voltage to the transistor of the light-emitting device during the light-emitting phase of the pixel circuit The leakage current of the pixel circuit can be reduced, thereby reducing the leakage current phenomenon in the pixel circuit, reducing the current difference of the pixel circuit driving the light-emitting device to emit light caused by the leakage current characteristic of the transistor, and improving the brightness uniformity of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a method and device for driving a display panel. Background technique [0002] As users have higher requirements on the display performance of display devices, the requirements on brightness uniformity of display panels are getting higher and higher. Due to the difference in performance of the transistors forming the pixel circuit in the display panel, the brightness uniformity of the display panel is relatively poor, which reduces the experience effect of the user. Contents of the invention [0003] The invention provides a method and device for driving a display panel to improve the brightness uniformity of the display panel. [0004] In a first aspect, an embodiment of the present invention provides a method for driving a display panel, where the display panel includes a pixel circuit; the method includes: [0005] setting the first initializa...
