Abstract
Several display regions are defined on a display panel, and each display region has its panel characteristic data. A pixel data is received and the determined display region of the pixel data is determined. The pixel data is calibrated according to the panel characteristic data of the determined display region, and then the calibrated pixel data is transmitted to the display panel.
Claims20
A method for compensating regional nonuniformity of a display panel, the method comprising:
- defining a plurality of display regions on the display panel, wherein each display region has panel characteristic data;
- receiving a pixel data;
- determining to which display region the pixel data corresponds for a determined display region;
- calibrating the pixel data according to the panel characteristic data of the determined display region for a calibrated pixel data;
- and
- correcting the display panel with the calibrated pixel data.
A method for compensating a pixel data, the method comprising:
- receiving the pixel data and determining to which display region on a display panel the pixel data corresponds by a display region interpreter;
- calibrating the pixel data by a panel characteristic corrector according to a panel characteristic data of the determined display region stored in a panel characteristic recorder;
- and
- adjusting the display panel according to the calibrated pixel data.
An apparatus for compensating regional nonuniformity of a display panel, the apparatus comprising:
- a display region interpreter arranged to determine to which display region a pixel data corresponds, wherein the display panel has a plurality of display regions;
- a panel characteristic recorder having panel characteristic data of the display regions, the panel characteristic recorder electrically connected to the display region interpreter and arranged to select the panel characteristic data of the determined display region;
- and
- a panel characteristic corrector electrically connected to the panel characteristic recorder and arranged to calibrate the pixel data according to the corresponding panel characteristic data.
