The Waffle barrier rib structure includes three first barrier ribs having different width and a plurality of second barrier ribs perpendicular to the first barrier ribs. The second barrier ribs are located between the two first barrier ribs, and connect the wider structure of the two first barrier ribs. Therefore, discharge spaces are formed. Because of different width, the height difference of the barrier rib structure is formed after thermal process. Hence, gas can pass through the barrier ribs structure between the front and the back substrate sealed together.

摘要： A method for adjusting a target gray level of a target pixel based on a spatial mask is provided. The target pixel is surrounded with N adjacent pixels; each of the N adjacent pixels respectively has an adjacent gray level. The method first multiplies the target gray level with a sharpness index to generate an amplified target gray level and respectively multiplies each of the adjacent gray level with an adjacent index to generate N modified adjacent gray levels. Then, the amplified target gray level and the N modified adjacent gray levels are added up to generate a first gray level sum. The method multiplies the first gray level sum with a multiplying parameter to generate a second gray level sum. At last, the method divides the second gray level sum by a dividing parameter to generate an adjusted gray level for the target pixel.

摘要： 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.
