摘要
随着各种分辨率LCD的广泛应用,一种通用的LCD显示控制器的研制与应用亟待发展。为了能够更加方便快捷地控制LCD的显示,文中以AT070TN92液晶为例,详细分析了显示控制器中的关键技术,采用了一种基于CPLD或FPGA的通用LCD显示控制器的方法,使LCD的显示控制以模块化的方式应用在各种嵌入式设备中。通过试验验证,这种方法不仅能够准确地实现标准时序下的液晶控制和驱动功能,而且其通用性强,可以在不更改上位机的控制代码的情况下,实现多种分辨率的标准显示功能。
With the wide range of applications in a variety of resolution LCD, a common solution of the LCD display controller yet to be developed. In order to control the display more quickly and easily, AT070TN92, for example, a detailed analysis of the key technologies in the display controller is described,and a general solution of display controller based on CPLD or FPGA is proposed as well, which can be used in a modular fashion in a variety of embedded devices. It is verified by experiments that this solution not only can control the display of LCD accurately,but also is versatile.The standard multi-resolution display is implemented without modifing the code of the host computer.
