Title: METHOD AND APPARATUS FOR MODULATING IMAGE DISPLAY QUALITY OF DISPLAY DEVICE
Abstract:
Provided are a method and apparatus for modulating the image display quality of a display device. The method comprises: setting the display device to modulation state, so that the common voltage of a preset gray level of the display device is a standard voltage; modulating the other common voltages of controllable gray levels of the display device to a preset value, the preset value and the standard voltage having a first preset relation therebetween. The method allows the common voltages of respective gray levels of the display device to be maintained at the same level, minimizing image sticking and improving the image display quality of the display device.
