A color adjustment device and method for the plasma display panel. The color adjustment device comprises a look up table and an error diffusion circuit. Wherein, the look up table is used to store a plurality of gray scale data, select one corresponding data from the plurality of gray scale data according to a received gray scale input value as an output. The error diffusion circuit receives the gray scale data output from the look up table, and achieves the objective of improving the color adjustment precision by using an error diffusion compensation method.
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 front panel structure of Plasma Display Panel (PDP) is disclosed sequentially comprising a first electrode, a second electrode and a third electrode, wherein the second electrode has transparent electrodes located on both top and bottom sides of a bus electrode. A first discharge center is formed between a transparent electrode of the first electrode and one transparent electrode of the second electrode. A second discharge center is formed between the other transparent electrode of the second electrode and a transparent electrode of the third electrode. Therefore, an emitting cell of PDP has two discharge centers. To make the discharge more stable, we choose the first electrode and the third electrode to become the scan electrodes, or to form a thicker dielectric layer or discharge deactivation film below the second bus electrode as a scan electrode.

A plasma display panel having a plurality of bi-discharge sources comprising a front substrate and a rear substrate coupled in parallel; a plurality of first electrodes, second electrodes and third electrodes in parallel disposed over the front substrate along a first direction; a plurality of rear substrate walls disposed in parallel over the rear substrate along a second direction orthogonal to the first direction. Each of the plurality of second electrodes is centered between each of the plurality of first and third electrodes, which leads to a bi-discharge source. In each of the plurality of second electrodes, one side is induced as having a plurality of positive charges and the other side with a plurality of negative charges, which are equal amount and thus result in charge counterbalance on the second electrode.
