In reference to the system block diagram of the monitor’s circuitry shown on the previous page, the analog RGB inputs are amplified and sent through an analog-to-digital converter (ADC) to a digital signal processor (DSP) that generates digital RGB signals for controlling LCA panel. BLOCK B. A second power supply converts a single 12V supply to the various voltages needed to run the LCD panel and the inverter driving the display’s backlights. BLOCK C. SYNC SIGNAL PROCESSOR. This processor determines the polarity of the horizontal and vertical sync signals, generates a fixed-polarity synchronized clock signal and provides data for use by the microprocessor in selecting circuit control parameters from EEPROM tables.
