Patent ID: 7535248

Claim:
A display, comprising: a substrate; a plurality of signal lines disposed on said substrate; a driving circuit, comprising: a plurality of integrated circuit (IC) pads, each of said IC pads being electrically connected to one of said signal lines; a multiplexer, disposed between said signal lines and said IC pads, directly connected with said signal lines, and adapted to transmit a test signal to a portion of said signal lines; a plurality of first test points disposed on said substrate—and electrically connected to said plurality of IC pads; a plurality of second test points disposed on the substrate electrically connected to said plurality of IC pads and said plurality of first switches; a plurality of second switches electrically connected to said plurality of first test points and said plurality of IC pads, wherein the number of said plurality of second switches is less than the number of said plurality of IC pads; and a plurality of first switches electrically connected to said plurality of first test point and said plurality of IC pads, wherein the number of said plurality of first test points is connected to a predetermined number of said IC pads respectively through said predetermined number of said first switches, and said predetermined number is larger than one.
