    Patent number: 5757346
    Abstract: A technique for inspecting a liquid-crystal display module which includes a liquid-crystal panel and a liquid-crystal display driving device, wherein the liquid-crystal display driving device is provided with a selecting section for selectively switching between (i) outputting of various data items stored in a memory section to an inspection device and (ii) outputting of the stored data to a driving section to drive a liquid-crystal panel, on the basis of execution instruction data from the inspection device. The inspection device selectively writes and reads character data into and from a DDRAM, a CGROM, and a CGRAM in the memory section of the liquid-crystal display driving device one after another and inspects the display in sequence.
