Abstract

The invention is applicable to the multimedia technology field and provides a liquid crystal display controller and an image data load method thereof. The method includes the following steps: an external program configures an image storage sequence marker bit of a register interface module to judge the image data storage sequence in real time; a data load control module inside the liquid crystal display controller reads out image data from a buffer area to respond to the image storage sequence marker bit information configured by the external program, adjust the image data storage sequence and output the adjustment result to an output interface time sequence generating module; and hardware realizes the quick bridging and adjusting of data. The invention can be realized easily, solves the problem of low adjustment efficiency of the image storage sequence adjustment proposal in the prior art and is suitable for a mobile multimedia application occasion which requires quite strong real-time property.

Description

technical field [0001] The invention belongs to the technical field of multimedia, and in particular relates to a liquid crystal display controller and an image data loading method thereof. Background technique [0002] With the continuous development of SOC (system on chip) technology, people have been able to integrate a very complex and huge system on a small chip, and the continuous leap of microelectronic technology has also changed people's lives. More powerful, more functional, and more affordable, most mobile multimedia devices have LCD displays. [0003] High-end liquid crystal displays (Liquid Crystal Display, LCD) are divided according to interface types, including microprocessor interfaces, RGB interfaces, etc. The LCD controller completes the refresh control of the LCD through the LCD driver chip inside the LCD. figure 1 It shows the connection structure of the LCD controller and the driving chip in the prior art. [0004] The LCD controller works like this. F...
