二、常见去隔行、SCALER芯片介绍液晶彩电中的去隔行处理与图像缩放SCALER电路的配置方案一般有两大类:一种是去隔行处理与图像缩放SCALER电路分别使用单独的集成电路,如图1所示;第2种电路配置方案是将去隔行处理、SCALER电路集成在一起(如图1所示),也就是说,它们是作为一个整体而存在的,我们一般将此类芯片称为“视频控制芯片”。随着集成电路的发展,视频控制芯片开始将A/D转换器、TMDS接收器(接收DVI接口信号)、OSD(屏显电路)、MCU、LVDS发送器等集
Second, the common deinterlacing, SCALER chip LCD TV deinterlacing and image scaling SCALER circuit configuration programs generally have two categories: one is to de-interlacing and image scaling SCALER circuit using a separate integrated circuit, as shown in Figure 1; the second circuit configuration scheme is de-interlacing, SCALER circuit integration (as shown in Figure 1), that is, they exist as a whole, we generally refer to such chips as “Video control chip ”. With the development of integrated circuits, video control chip began to A / D converter, TMDS receiver (receiving DVI interface signal), OSD (OSD), MCU, LVDS transmitter and so on
