1373759 IX. Description of the invention: [Technical field of the invention] The present invention relates to a kneading system and an adjustment method, and more particularly to a method for controlling the display of picture data in a centered position of a panel by controlling timing adjustment. Surface adjustment system and method. [Prior Art] The first figure is a schematic diagram of a conventional liquid crystal display architecture. The liquid crystal display device mainly includes a display panel 200 for displaying a facet and a timing controller 100 for controlling the display panel 200. With the second picture:, is the timing waveform diagram of the timing controller. The timing controller 1 generates an image data LDD and a timing control command S1 according to the external data Data_In (the timing control command S1 includes a vertical synchronization signal VSYNC, a horizontal synchronization signal HSYNC, a resource enable signal 0E, and A clock ακ). The timing controller 100 superimposes the vertical synchronizing signal VSYN and the horizontal synchronizing signal HSYNC to control the column driver 2 and the row driver 204 respectively, and further cooperates with the data enable signal OE to send the image data LDD to the display panel 2〇. 〇, and 1. The display panel 2 〇〇 displays an output pupil 202. The timing controller 1 is integrated with the technology of the specific application integrated circuit (ASIC) according to the matching display panel 2〇〇, so the same type of timing controller 1〇〇 cannot be used for different specifications. The display panel 200. Therefore, in conjunction with the second figure, the timing controller 1 in the first figure, the timing control command S1, can control the display panel 202 having an 800 χ 600 size to display an output buffer 202 of 800 χ 600 pixels. However, if the same type of timing controller 100 is used in the control of different specifications 856χ 600 size display panel 300 (refer to the third figure), the same sequence control command S1 will not allow the image data LDD to be displayed.
