Abstract
An image processing method for plasma display panels is disclosed to measure the difference of displayed brightness, color temperature and color shift as a result of the voltage drop under various operation modes. The measured data are made into a lookup table installed in the circuit board so that the circuit board can automatic calibrate the image shown on the plasma display panel.
Claims10
An image processing method for a plasma display panel (PDP) that contains a plurality of electrodes and a circuit board, the method comprising the steps of:
- measuring the loading ratios of said electrodes under a plurality of operation modes;
- measuring the red, green, and blue (RGB) gains and brightness gains under different loading ratios to establish a lookup table;
- loading said look-up table into said circuit board;
- and
- determining the current operation mode and the corresponding electrode loading ratios after inputting an original image to calibrate the RGB gray levels and brightness according to said look-up table of said circuit board to output the calibrated image.
