  • Patent number: 8208113
    Abstract: A pixel structure including a substrate, a scan line, a data line, a common line, an active device, a pixel electrode, a passivation layer and a transition auxiliary electrode is provided. The scan line and the data line on the substrate intersect with each other to define a pixel region. The common line on the substrate is parallel to the scan line. The active device disposed within the pixel region is electrically connected to the scan line and the data line. The pixel electrode disposed within the pixel region is electrically connected to the active device. The passivation layer is between the data line and the pixel electrode. The transition auxiliary electrode is adjacent to the periphery of the pixel electrode and electrically connected to the common line through a contact hole of the passivation layer. The transition auxiliary electrode and the pixel electrode are made of the same film.

  • Patent number: 7812352
    Abstract: A TFT array substrate is disclosed. In the pixel structure of the TFT array substrate, patterned transparent conductive layers are disposed under a first metal layer (M1) and a second metal layer (M2) and most areas of the M1 and M2 are substituted by the patterned transparent conductive layers. So, the pixel structure has high aperture ratio and large storage capacitance. Besides, a scan bonding pad on the TFT array substrate includes a first patterned transparent conductive layer (T1), the M1 and a third patterned transparent conductive layer (T3). The M1 is disposed on the T1, and the T3 is electrically connected to the T1 via a contact hole in the M1. So, the contact resistance of the scan bonding pad is small. The data bonding pad on the TFT array substrate has similar design. Moreover, fabricating methods of TFT array substrates are also provided.

  • Publication number: 20080278646
    Abstract: A pixel including a transistor, a liquid crystal capacitor, a storage capacitor and a coupling capacitor is provided. The first end of the transistor is connected to a data line, the liquid crystal capacitor and the storage capacitor are coupled between the second end of the transistor and a common voltage, and the coupling capacitor is connected between the second end of the transistor and a select line. After a driving voltage is outputted to the liquid crystal capacitor and the storage capacitor by the data line, the select line inputs a pulse signal to the liquid crystal capacitor through the coupling capacitor. The pulse signal is capable of increasing the ability of the electric field for driving the liquid crystal so that the liquid crystal can still display normally in the bend state even though the lowest pixel voltage is lower than the critical voltage.
