Publication number: 20060114273Abstract: Test data terminals R-DATA, G-DATA, and B-DATA are provided with respect to video signal lines VL-R, VL-G, and VL-B, via switches SW-R, SW-G, and SW-B, respectively. The switches SW-R, SW-G, and SW-B are turned ON by receiving an H level input signal supplied from a test terminal SW. Thus, a test of a panel is performed before an external IC is connected to the panel. When the external IC is connected to the panel, on the other hand, these terminals used for the test are fixed to an L level, thereby preventing abnormal operations.Type: ApplicationFiled: November 29, 2005Publication date: June 1, 2006Inventors: Masahiro Okuyama, Koji Hirosawa, Yusuke Tsutsui, Yukitada Iwasaki, Yasushi Miyajima
