专利汇可以提供Color monitor receiver专利检索,专利查询,专利分析的服务。并且PURPOSE:To reproduce a color picture with correct color by providing a clamp circuit to a signal line in common of analog three primary color signals and binary three primary color signals and a blanking circuit to a signal line of the binary three primary color signals respectively. CONSTITUTION:Digital color signals Rd-Bd are applied to terminals 1R-1B, then the distortion of the waveform is shaped in the signals Rd-Bd by buffers 6R-6B into a rectangular wave. Since the level of the blanking pulse Rk formed by applying synchronizing pulses Ph, Pv to a pulse forming circuit 12 is at ''0'' in the horizontal scanning period, transistors Q1-Q3 are turned off and the signals Rd-Bd are applied to a picture tube 5 through a path of resistors R1- R3 switches 2R-2B amplifier 3 clamp circuit 4. Thus, even if the signals Rd-Bd are pedestal-clamped by the clamp circuit 4, since the level ''0'' of the signals Rd-Bd is clamped to black color of the reproduced screen, correct color picture is reproduced.,下面是Color monitor receiver专利的具体信息内容。
