    6.2 Circuit Operation Theory I. Introduction: V223HQ is a 21.5 inch and 24bits color TFT LCD monitor, which can support the resolution up to 1920x1080. It has VGA input and compliant with VESA specification to offer a smart power management. The monitor has DDC/CI function to make the monitor communicate with PC by Acer ADM DDC/CI software, and also it has ACM function to let the monitor contrast ratio up to 50000:1.
  • Page 61 III. Circuit Implementations: THE MAIN BODY: A-1.) Interface board block diagram: (a) Circuit operations: The scaling IC has OSD and auto detecting input timing functions. OSD offers adjustable functions to the end- users. Auto detecting timing function can detect change modes. It outputs the digital R-G-B data, pixel clock and control signal to TCON of the LCD module.
  • Page 62 modules. In addition, RTD2555LH embedded 16.5KSRAM dynamically stores OSD command and fonts, compatible advanced color control features. EEPROM: We use 24C16 EEPROM to store monitor user data and user preset timings. There are 16 user timing modes are automatically saved in it. Each timing mode is allocated with 22 bytes of memory space for information such as Sync frequencies, polarities…...
