Patent ID: 7893931

Claim:
A display device, comprising: a pixel array comprising a plurality of scan lines; and a shift register array, comprising: a plurality of first shift registers, each first shift register comprising a signal input terminal and a signal output terminal, the signal output terminal being predetermined to be electrically connected with corresponding one of the scan lines; a second shift register comprising a signal input terminal and a signal output terminal; a first connection line, connected to the signal input terminal of the second shift register, for overlapping the signal output terminal of each first shift register without electric connection; a second connection line connected to the signal output terminal of the second shift register; and a third connection line for establishing a plurality of electric connection paths with the second connection line, and overlapping the signal output terminal of each first shift register without electric connection, wherein the number of the electric connection paths is the same as the number of the first shift registers; wherein when one of the first shift registers malfunctions, the overlapping point of the signal output terminal of a previous stage of the malfunctioned first shift register is electrically connected to the first connection line, the overlapping point of the signal output terminal of the malfunctioned first shift register is electrically connected to the third connection line, and the electric connection of the signal output terminal of the malfunctioned first shift register and the corresponding scan line is adjusted to electric disconnection.
