ABSTRACT:
A single IC-chip includes a video processor, a panel processor, an OSD circuit, a CPU, and a timing controller. A memory18stores one test pattern datum that is formed of one font datum of X dots in width and Y dots in height in order to test the position of any bright point, dark point, bright line or dark line on the screen of the liquid crystal panel. At a test step, the CPU acquires the test pattern datum from the memory, and a test pattern is created by the OSD circuit so as to display the test pattern at any desired position on the screen of the liquid crystal panel and to simultaneously display the address values of the origin of the display position of the test pattern.
