Abstract

The invention provides a display panel charging method and device and a display panel. The display panel comprises an IC chip, an amplifier, a plurality of charging lines and a plurality of sub-pixels, each charging line is connected with the plurality of sub-pixels, the IC chip is connected with the plurality of charging lines through the amplifier, the IC chip sequentially outputs bias currentsto a plurality of charging lines through an amplifier so as to charge sub-pixels connected to the corresponding charging lines, and the method is applied to the IC chip and comprises the steps of acquiring expected brightness values of the sub-pixels connected to a current to-be-charged line, determining a gray scale interval corresponding to the current to-be-charged line according to the expected brightness values of the plurality of sub-pixels corresponding to the current to-be-charged line, determining a target bias current according to the gray scale interval corresponding to the currentto-be-charged line, and outputting a driving current corresponding to the target bias current to the amplifier, so that the amplifier outputs the target bias current to the current to-be-charged line.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular, to a display panel charging method and device, and a display panel. Background technique [0002] When the display panel uses IC chips and amplifiers to charge the lines and the sub-pixels connected to the lines, the required display brightness of different lines will be different, and the existing charging method is regardless of the required display brightness of different lines. The IC chip will control the amplifier to output according to the same bias current. In order to make the one with high brightness meet the requirements, the bias current with the highest brightness is generally used for output. Therefore, there are problems when using the above method to charge the display panel. A case of high power consumption. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a display panel charging method,...
