like figure 1 As shown, the timing signal SA is transmitted to the first data line driving circuit 16A through a first transmission line 28A, and transmitted to the second data line driving circuit 16B through a second transmission line 28B. However, since the length of the first transmission line 28A is longer than that of the second transmission line The length of the second transmission line 28B, so as figure 2 As shown, the delay time (delay time) T1 of the timing signal SA transmitted to the first data line driving circuit 16A and the delay time T2 of the timing signal SA transmitted to the second data line driving circuit 16B will be different, and when the delay time T1 When the difference t between the delay time T2 and the delay time T2 is greater than a certain allowable time interval, the picture displayed on the display area 14 will flicker.

A circuit layout method for polysilicon thin film transistor LCD display which comprises a panel, multiple display units; time sequence control circuit generating time sequence signals and multiple logic circuits which can control the operations of display units according to time sequence signals. The method in this invention determines the position formed by time sequence circuit in the panel to make the time lag is less than 10#+[-6] seconds from time sequence signals to multiple logic circuits.
Description
technical field [0001] The present invention relates to a circuit layout method of a polysilicon thin film transistor liquid crystal display, in particular to a method for determining the position of a timing control circuit of a polysilicon thin film transistor liquid crystal display in a liquid crystal panel to improve the imaging quality of the polysilicon thin film transistor liquid crystal display . Background technique [0002] Liquid crystal displays have the characteristics of light, thin, low power consumption, and no radiation pollution. They have been widely used in portable information products such as notebook computers (notebooks) and personal digital assistants (PDAs), and have even gradually replaced them. Trends in cathode ray tube (CRT) monitors for traditional desktop computers. Since liquid crystal molecules have different polarization or refraction effects on light in different alignment states, the amount of light transmission can be controlled through...
