Patent number: 8928550Abstract: A driver chip for controlling a high-resolution display panel is presented. The driver chip is not much larger than a conventional driver chip that is currently used for lower resolution display panels. The driver chip applies data signals to the data lines of the display panel and gate control signals to a gate driver that is formed in the peripheral region of the display panel. The gate driver, which may be made of amorphous silicon TFTs, generates gate signals in response to the gate control signals from the driver chip and applies the gate signals to gate lines. Since the driver chip of the invention controls more gate lines and data lines than a conventional chip of about the same size, the driver chip may be easily adapted for display devices having multiple panels. Where multiple panels are used, the panels may be scanned simultaneously or sequentially.Type: GrantFiled: May 13, 2008Date of Patent: January 6, 2015Assignee: Samsung Display Co., Ltd.Inventors: Young-Bae Jung, Won-Kyu Lee, Jin Jeon, Ji-Suk Lim, Min-Kyung Jung, Eung-Sang Lee, Won-Seok Ma
