  • Publication number: 20090261339
    Abstract: In a method of making device of a display, an insulating layer, a semiconductor layer, an ohmic contact layer, a second conductive layer, and a photoresist pattern are consecutively formed on a first conductive structure. The photoresist pattern includes a first thickness region, and a second thickness region outside the first thickness region. The thickness of the second thickness region is smaller than that of the first thickness region. In addition, in a gate driver on array (GOA) of a display, it includes a gate driver on array structure with a pull-down transistor. The pull-down transistor has a gate electrode, a semiconductor island, a source electrode and a drain electrode. The semiconductor island extends out of the edges of the gate electrode, the source electrode, and the drain electrode.

  • Publication number: 20090231310
    Abstract: A gate driver-on-array structure integrated into a display includes a substrate and a gate driver structure formed thereon. The gate driver structure is disposed in a peripheral region of the substrate. The gate driver structure includes a first layer metal pattern, a second layer metal pattern, and an insulating layer disposed therebetween. The first layer metal pattern includes connection nodes. The insulating layer has through holes exposing the connection nodes. The second layer metal pattern fills into the through holes and in contact with the connection nodes of the first layer metal pattern so as to implement necessary electrical connection of the gate driver structure.

  • Publication number: 20090115954
    Abstract: An LCD panel including a first substrate, a second substrate, a black matrix, a liquid crystal (LC) layer, first photo spacers and second photo spacers is provided. The first and the second substrates are substantially parallel. The LC layer is disposed between the first and the second substrates. The black matrix disposed on the first substrate surrounds display regions and defines a non-display region. The first photo spacers contact the second substrate and are disposed on the black matrix. The second photo spacers are disposed on the black matrix. Channels are formed between the second photo spacers, such that LC molecules of the LC layer flow between the display regions through the channels. The width of the channels between any two of the adjacent second photo spacers substantially ranges from 2˜10 ?m. The dimension of the first photo spacers is substantially greater than that of the second photo spacers.
