1.SAA8103 is selected to generate the driver pulse for the CCD. It is combined with the V-driver IC(TDA9991) to generate the vertical driving signals and also connected with the chip 74ACT04 logic drivers to generate horizontal driving signals.
集成芯片SAA8103为驱动CCD芯片提供脉冲信号,与TDA9991协调工作产生CCD垂直行驱动时钟,与74ACT04芯片配合产生驱动CCD芯片的水平像素转移时钟。收藏指正
2.In order to reduce the power consumption and improve image quality in color plasma display panel(PDP), the data change rate of image in vertical direction at each subfield that causes most address power consumption is analyzed. Based on the principle of automatic power control(APC), the method for APC is developed. It includes image sticking minimization mode, relationship between average picture level and the number of sustain pulse, and relationship between display load ratio and luminance as well as power consumption.
为降低彩色等离子体显示器(PDP)的功耗,提高图像质量,在分析了寻址功耗和图像数据在各子场列方向上的变化率有关的基础上,根据自动功率控制(APC)的原理提出了自动功率控制的方法,该方法的主要内容包括:图像最小残像工作模式,图像信号的平均强度和维持脉冲数的关系,图像负载率和亮度及功耗的关系等。收藏指正
