  • Patent number: 8659527
    Abstract: An active device array substrate including a substrate, a plurality of pixel structures and a plurality of resistance compensating devices is provided. The substrate has a display region and a scanning signal input region beside the display region. The pixel structures are disposed in the display region. Each of the pixel structures includes a scan line, a data line, an active device and a pixel electrode. The data line is disposed in stagger with the scan line. The active device is electrically connected with the scan line and the data line. The pixel electrode is electrically connected with the active device. Each of the resistance compensating devices and a scan line of a corresponding pixel structure are connected in parallel. Resistances of the resistance compensating devices gradually decrease from a region close to the scanning signal input region to another region away the scanning signal input region.

  • Publication number: 20120257296
    Abstract: A color filter substrate includes a transparent plate, a black matrix, a plurality of filter layers, a plurality of first support pads, and a transparent conductive layer. The transparent plate has a plane. The black matrix is disposed on the plane and has a plurality of grid areas. The filter layers are disposed on the plane and located in the grid areas respectively. The first support pads partially cover the black matrix. Each of the first support pads is located among adjacent four filter layers. An area on the black matrix covered by each of the first support pads is in a shape of a cross. The first support pads are connected to the filter layers. Each first support pad includes a first pad layer, a second pad layer, and a third pad layer. The transparent conductive layer covers the filter layers, the first support pads, and the black matrix.

  • Publication number: 20070273283
    Abstract: A plasma display panel and method for adjusting color temperature therefor are provided, including the steps of providing a mixed fluorescent material, a green fluorescent material, and a blue fluorescent material, and then coating the mixed fluorescent material into a rib of each red sub-pixel, coating the mixed fluorescent material into a rib of each green sub-pixel, and coating the blue fluorescent material into a rib of each blue sub-pixel. The red light-emitting portion of the plasma display panel is mixed with a proper amount of the blue fluorescent material so as to achieve a higher color temperature of the red light-emitting portion and thus a higher color temperature of the overall display panel.
