3)LED数码管显示电路我国早期产并采用SGSM491B(或M494)遥控系统的彩电(如熊猫牌3608型、厦华牌XT5125型、金星牌C512型、百花牌MV—5186型、康力牌CDT—9582型等)和早期进口并采用HD44840A65微处理器的彩电(如法国汤姆逊TFE5114DK型,西德沙巴T51SC32DTC20型等)控制信息的显示电路采用LED数码管显示器。它是由微处理器M491B/M494或HD44840A65直接驱动二位数七段发光数码二极管(LED)显示器,显示频道号和模拟量控制大小等,显示内容比较少。由于LED显示器是单独设置在电视机面
3) LED digital tube display circuit Our early production and use SGSM491B (or M494) remote control system of color TV (such as the Panda 3608, Xoceco XT5125, Venus C512, -9582-type, etc.) and the early import and use HD44840A65 microprocessor color TV (such as the French Thomson TFE5114DK type, West Sabah T51SC32DTC20-type, etc.) control information display circuit using LED digital tube display. It is directly driven by the microprocessor M491B / M494 or HD44840A65 two-digit seven-segment light-emitting digital diode (LED) display, display channel number and analog control size, display less. Because the LED display is set separately on the TV side
