  • Page 57: Circuit Operation Theory

    6.2 Circuit Operation Theory I. Introduction H233H is a 23 inch and 24bits color TFT LCD monitor, which can support the resolution up to 1920x1080. It has VGA, DVI and HDMI input and compliant with VESA specification to offer a smart power management.
  • Page 58 III. Circuit Implementations: A.) 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 59 output section contains a 24-bit TTL output interface and a channel LVDS transmitter for direct interfacing of commercially available LVDS LCD panel modules. In addition, RTD2525LH embedded 16.5KSRAM dynamically stores OSD command and fonts, compatible advanced color control features. 2.) EEPROM: We use 24C16 EEPROM to store monitor user data and user preset timings.
