基于DSP的LCD的应用研究

LCD displays have many other incomparable advantages, as shown zero radiation, low power consumption, small size, Screen convenient adjustment, the screen flickered a stable, so widely used in all kinds of intelligent devices and low-power electronic products. Unceasingly emerges along with LCD component widespread application and the new liquid crystal material, the people are more and more high to the liquid crystal performance request. The liquid crystal material certain important parameters have the important influence to its demonstration characteristic, traditional liquid crystal testing device only test the liquid crystal material some transient state performance, the function are unitary, the use are not convenient. DSP based on LCD can eliminate these shortcomings, it will combine the advantages of both, facilitate more people to study and work. This article has outlined the DSP component development and the application, studies a display system which take the TMS320C5402 as control module and take the TMS12832ABC as display module, it has analyzed the DSP chip principle of work and the LCD demonstration principle. And from the hardware and the software, it has carried on the system design. Finally, this article also makes the summary, further has analyzed the display system development direction, and estimated the question that may meet, simultaneously proposed own opinion.
