Liquid crystal display apparatus

摘要

An LCD apparatus, when fed with images in a video format whose pixel configuration is smaller than that of the LCD screen, fills the resulting blank area with a particular color through simple and low-speed image data processing. This LCD apparatus has rewritable memories, 24-bit latch circuits that cooperate with a blue-fill circuit and a black-fill circuit to write data of a particular color to the memories at all the addresses corresponding to the LCD screen, an overwriter for overwriting the memories with input image data only at the addresses corresponding to the area of the LCD screen in which images are displayed, and a reader for reading all the data stored in the memories to feed it to an LCD module.
