一种低成本的RGB全彩显示屏控制器的开发

The Development of a Low Cost RGB Full-color Display Controller

RGB色彩模式是工业界的一种颜色标准,是通过对红(R)、绿(G)、蓝(B)三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色的。RGB是目前运用最广的颜色系统之一。然而目前市面常见的RGB多为高端控制器,芯片主频高,同时也价格不菲,对于中低端用户而言使用成本较高,因此作者设计了一种基于STC12系列单片机的低成本的RGB控制器,能满足中低端应用需求。

RGB color model is the color standard in industry. It gets all kinds of colors by changes of Red（R）, Green（G）, Blue（B）, these 3 colors ＇channels and the superposition of each other. RGB is one of the most used color systems. However, RGB is common seen in high quality controllers on present market. The dominant frequency of chip is high, But they are very expensive. So it will bring high cost of use to mid-and low-end users.Therefore, the designer designs one RGB controller of low cost based on SCM STC12 series. It can meet the low end of the application needs.
