摘要:
Brightness correction apparatus and method for a plasma display, where the non-linear relationship between the gray scale and the brightness of the plasma display is considered. The brightness error is measured to build up a brightness error table. When the gray scale data of the currently displaying pixel is received, the brightness error diffusion method is applied. The weighted display brightness error of the neighboring pixel is incorporated for calculation to obtain an optimal display result. When the modified output gray scale data is derived by calculation, the brightness error table is looked up, and the display brightness error of the currently displaying pixel is thus saved to provide modification calculation for other pixels.

A driving electrode structure of a plasma display panel is described. The driving electrode structure has a driving electrode located in one luminant cell of each pixel. The driving electrode is formed on a transparent electrode and separated by a distance from the side of the transparent electrode adjacent to the edge of the luminant cells. The driving electrode has two branches coupled to a main electrode or a side electrode at the side of the transparent electrode adjacent to the edge of luminant cells. The driving electrode approximates the discharge center of the luminant cell to improve the driving characteristic.

An electrode structure with white balance adjustment for plasma display panel is described. The electrode structure has a comb electrode, a first transparent electrode and a second transparent electrode. The first transparent electrode and the second transparent electrode are separated from the comb electrode, respectively. Changing the profile of the first transparent electrode and the second transparent electrode increases the flexibility of the transparent electrodes. Further, the width of the first electrodes responsive to the luminous regions is adjusted to control the luminance through the first transparent electrode so that white balance of the plasma display panel is precisely corrected.

A method and an apparatus for improving the gray-scale linearity of a plasma display. At least two types of gray-scale allocations are mixed for forming the original gray scale, or different gray scales are mixed to derive the original gray scale, so as to obtain the required brightness. Therefore, by using multiple combinations to adjust the original gray scale, the required brightness is obtained, and the gray scale linearity for all the gray scales is improved.
