1. Interface Board 1.1 Power Supply (DC/DC Converter) IC100 is a linear regulator that converts a 12V DC input voltage into regulated and stable output voltages of 5V respectively. 1.2 Micro-Controller IC400 (scalar) built-in an micro-controller and an extra flash ROM (IC402---39SF010). It plays a major role in the digital control of the LCD monitor. IC400 acts as a Key control, DPMS power saving control, auto-detect controller, and controller of IC400 to do image process.
1.3. Image Processor IC400 (gm5120) is an all-in-one image processor for displays with a dual (analog and digital) interface supporting resolutions up to SXGA. It provides integrated ADC/PLL and a DVI compliant TMDS receiver and MCU, a high quality zoom and shrink scaling engine, an on-screen display(OSD) controller, a microprocessor and many other functions in a single device. This high level of integration enables simple, flexible, cost-effective solutions featuring fewer required components.
The gm5120 OSD controller supports both character-mapped and bitmapped modes. A user programmable palette of 256 true colors (255 colors, + 1 transparent) is available. In character mapped mode, a maximum of four colors per character are available. In 8-bit bitmapped mode, any pixel can be assigned any one of 256 user-defined true colors. In 4-bit bitmapped mode, any pixel can be assigned any one of 16 user-defined true colors (15 colors plus one transparent).
When transmitting, data bits D0 through D27 are each loaded into registers upon the edge of the input clock signal (CLKIN). The rising or falling edge of the clock can be selected by way of the clock select (CLKSEL) terminal. The frequency of CLKIN is multiplied seven times ( ) and then used to unload the data registers in 7-bit slices and serially. The four serial streams and a phase-locked clock (CLKOUT) are then output to LVDS output drivers. The frequency of CLKOUT is the same as the input clock, CLKIN.
1.5 DDC 1/2 B IC600 (24LC02) & IC602 (24LC21A) can continuously transmit its extended identification, “EDID” using DDC1 communication channel. In addition, the monitor can respond to a request for EDID, or complete VDIF, to be transmitted using DDC2, level B commands. Pin6 SCL is clock input for DDC 2B, pin5 SDA for data input, and pin7 VCLK is clock input for DDC1.
