Embodiment Construction

[0018] Please refer to FIG. 2 , which is a block diagram of a display unit according to a preferred embodiment of the present invention. The display component 200 includes a display panel 230 , integrated components 221 , 222 and 223 and a display driver chip 210 . The display driver chip 210 is used for receiving the system signal S1 output by the system 250 to drive the display panel 230 and the integrated components 221 to 223 . In this embodiment, the display driver chip 210 is electrically connected to a display panel. In actual application, the display driver chip can also be directly disposed on the display panel, such as a Low Temperature Poly-Silicon (LTPS) display panel.

[0019] The display driver chip 210 includes an input / output interface circuit 211 , an index register 212 , a control register 213 , an integrated device interface circuit 214 and a display driver circuit 215 . The input / output interface circuit 211 is used for receiving the system signal S1 and o...
