Abstract

The invention provides a virtual pixel voltage adjustment method, a display panel and a storage medium. By collecting the voltage data of a pixel in a display screen, it is judged whether it belongs to the same gray scale value, and the actual voltage value of the virtual pixel is adjusted to the collected gray scale value. The voltage value corresponding to the step value, thereby solving the problem in the prior art that the setting of the edge column signal affects charging and causes bright and dark lines. And when the screen is switched, the virtual pixel can be dynamically adjusted according to the detected gray scale value change.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a virtual pixel voltage regulation method, a display panel and a storage medium. Background technique [0002] Such as figure 1 In the pixel structure shown, a row of dummy pixels 10 (dummy pixels) are added to the left and right edges of the panel. The dummy pixels 10 do not function as displays and can be connected to electrical signals, but cannot be output. When the column inversion (column) driving method is used, it is set by the common electrode chip of the array substrate, and the data line signal of the most edge column provides a voltage signal for the dummy pixel 10. If the voltage corresponding to the fixed gray scale is adopted, the data signal of the edge column Toggle back and forth between high and low voltages, and the non-edge column data signals are DC signals of fixed voltages. [0003] Such as figure 2 As shown, the data voltages take 200 gray sc...
