Embodiment Construction

[0052]Please refer to FIG. 2A , which shows a schematic diagram of a liquid crystal display using a Chip On Glass (COG) package according to a preferred embodiment of the present invention. The liquid crystal display 200 includes: a panel 210, a plurality of source drivers (Source Driver, S / D) 212(1)-211(10), at least one gate driver (Gate Driver) 214, a printed circuit board 220 and a flexible circuit board 230 and 232. The source driver 212 and the gate driver 214 are disposed on the glass substrate of the panel 210 . The timing controller 225 is arranged on the printed circuit board 220 to receive image data and control signals, and then transmit them to the source drivers 212(3) and 212(8) through flexible circuit boards (FPC) 230 and 232 after processing. The source drivers 212(3) and 212(8) respectively transmit the received image data and source control signals to the adjacent source drivers 212(1), 212(2), 212(4) through the wires on the glass substrate. ), 212(5) an...

Abstract

The invention relates to a liquid crystal display encapsulated by glass flip chip and the data-transfer method. The LCD includes a plurality of serially-connected source electrode drivers and at least one grid electrode driver, a time schedule controller and at least one flexible circuit board. The source electrode driver and the grid electrode driver are arranged on a glass substrate by utilizing the method of glass flip chip encapsulation. The flexible circuit board respectively receives the image data and the control signals of the time schedule controller to send the image data and the control signals to the corresponding source electrode driver, then the received image data and control signals are sent to the adjacent source electrode drivers by the corresponding source electrode driver to lead all the source electrode drivers to obtain the required image data and control signals. The flexible circuit board is arranged in a way which can lead all the source electrode drivers to have acceptable signal delay and distortion.

Description

[0001] This application is a divisional application of an invention patent application with an application date of March 31, 2005, an application number of 200510062825.7, and an invention title of "LCD with chip-on-glass packaging and its data transmission method". technical field [0002] The invention relates to a liquid crystal display, in particular to a liquid crystal display adopting chip-on-glass package (Chip On Glass, COG). Background technique [0003] In view of advantages such as lightness, thinness and low radiation, liquid crystal displays have gradually replaced cathode ray tube (CRT) displays and become the mainstream of computer screens and televisions. In addition to improving the display quality of LCDs, such as color, contrast, and brightness, manufacturers are also committed to improving their production technology to speed up the production process and reduce production costs. [0004] The liquid crystal display uses a timing controller, a source drive...
