The invention discloses a liquid crystal graph display controller, which is used for conveying data to be displayed on a liquid crystal display. The liquid crystal graph display controller comprises a serial interface module, a peripheral micro-control module, a storage module, a display control module, a cache module and a color interface module, wherein the inside of the display control module is provided with a first-in first-out storage circuit; the peripheral micro-control module is connected with the cache module by the first-in first-out storage circuit; the first-in first-out storage circuit adopts a first-in first-out strategy to store data; and the cache module also adopts the first-in first-out strategy to store data. The liquid crystal graph display controller disclosed by the invention has the beneficial effects that the liquid crystal display screen has a high display response speed in a first-in first-out (FIFO) interruption mode, and the whole system has good instantaneity and is unlikely to generate a blurred screen phenomenon. The display control module can process a great quantity of data (within 2kb) once in the communication process with the peripheral micro-control module.
Description
technical field [0001] The invention relates to the field of graphic display controllers, in particular to a liquid crystal graphic display controller. Background technique [0002] Thin-Film-Transistor LCD (TFT-LCD) was born in the late 1980s and made a huge leap in technology in the 1990s, causing huge changes in the notebook computer, desktop monitor and TV market. Before 1995, the application of TFT-LCD was mainly concentrated in noble consumer products such as high-end camera monitors, high-end handheld game consoles, miniature TV sets and large-screen projectors. However, with the continuous price reduction of raw materials and the continuous improvement of production technology, the price of TFT-LCD has dropped astonishingly. The wider it is, gradually replacing the original monochrome LCD, pseudo-color LCD and other display devices. Now TFT-LCD occupies more than half of the electronic display market and has become the mainstream display device, so various TFT-LCD ...
