  • Publication number: 20060054896
    Abstract: An active plate (2) for an active matrix display device (16), the active plate (2) comprising a substrate (4), a pixel area (6) and an adjacent drive circuit area (8). Both areas include polycrystalline silicon material formed by a process in which a metal is used to enhance the crystallisation process (MIC poly-Si), but only the MIC poly-Si in the drive circuit area (8) is subjected to an irradiation process using an energy beam (10). TFTs are fabricated with MIC poly-Si which have leakage currents in the off state sufficiently low for them to be acceptable for use as switching elements in the pixel area of matrix display devices. As only the drive circuit area (8) need be irradiated to provide poly-Si having the desired mobility, the time taken by the irradiation process can be significantly reduced.

  • Publication number: 20060044247
    Abstract: A built-in gate driver having an improved reliability and a display device having the same are provided. A transistor controlled by an output signal of a next stage is further provided and thus a node (Q) is rapidly discharged. Accordingly, the multi-output signals due to the reduced discharge of the node (Q) caused by the degradation of the transistor controlled by a node QB can be prevented. By including only one transistor for controlling the charge of the start pulse signal on the node (Q), it is possible to prevent a malfunction from occurring when the transistor connected to the clock is degraded by the periodic clock of a high state. Also, an image quality and the reliability of the gate driver can be improved.
