  • Patent number: 7485203
    Abstract: An assembly method for display panel comprises the following steps. First, a first substrate and a second substrate are placed inside a chamber, wherein the first substrate comprises a sealant disposed thereon, and the chamber has a first pressure. Next, the pressure inside the chamber is adjusted to a second pressure, which is lower than the first pressure. After that, the first substrate is aligned with the second substrate, and the second substrate is placed on the sealant, to form a closed space between the first substrate and the second substrate. The pressure inside the closed space is the second pressure. Thereafter, the chamber is pumped from the second pressure to a third pressure, to bond the first substrate and the second substrate together by the pressure difference between the third pressure of the chamber and the second pressure of the closed space. Finally, the sealant is cured.

  • Publication number: 20080239183
    Abstract: A stacked storage capacitor structure for use in each pixel of a TFT-LCD, wherein a first storage capacitor is formed by a first metal layer, a gate insulator layer and a second metal layer. The second capacitor is formed by the second metal layer, a passivation insulator layer and an ITO layer. The first metal layer and the ITO layer are joined together through a via hole which is etched in one insulator etching step during the overall fabrication process through both the gate insulator and the passivation insulator layers. As such, the two capacitors are connected in parallel in a stacked configuration. With the stacked storage capacitor structure, the charge storage capacity is increased without significantly affecting the aperture ratio of a pixel. The ITO and the pixel electrode can be different parts of an indium tine oxide layer deposited on the passivation insulator layer.
