    Abstract: A removing method of a flexible device is provided. The flexible device is formed on a carrier. The removing method of the flexible device includes providing a roller, a non-visible light source, and a photosensitive tape. The non-visible light source is disposed at an axle center of the roller, and the photosensitive tape is fixed on an outer surface of the roller. The removing method of the flexible device further includes enabling the photosensitive tape on the roller to lean against the flexible device and enabling the roller to rotate so as to peel the flexible device off the carrier; and irradiating the photosensitive tape by the non-visible light source and removing the flexible device from the photosensitive tape. As such, technique costs are saved and damages on the flexible device are lowered.

  • Patent number: 7764761
    Abstract: A shift register apparatus and a method thereof are provided. The technique manner submitted by the present invention utilizes two NMOS transistors for pulling down the voltage level of the scan signals output by the shift registers within the shift register apparatus to the low level gate voltage, wherein one of the NMOS transistors is controlled by a control unit, and the other NMOS transistor is controlled by a clock signal or the inverted clock signal provided to the shift registers. Therefore, shifting amount of the threshold voltage of those NMOS transistors can trend to be flat, and the reliability of those NMOS transistors can be promoted. In addition, since only one control unit is needed to dispose in each shift register so that the layout area of whole shift register apparatus can be reduced, and the panel with narrow frame size also can be achieved by the present invention.
