This section describes the function of the LCD monitor per functional block.
button board.
1. MB BOARD
The MB board is a four-layer, single-landed design with ground and internal planes provided.
The VGA cable is a signal cable that contains video signal, sync signal and DDCsignal from PC VGA adapter.
This system board consists of 3 functional areas : flat panel controller, flash ROM and LVDS transmitter.
1.1 Flat panel controller…… gm2120 (U8)
The heart of the system board is Genesis gm2120. The gm2120 is a graphics processing IC for LCD
monitor. It provides all key IC functions required for LCD panel. On-chip functions include a
high-speed triple-ADC , PLL, high sacling engine, OSD controller and on-chip microcontroller.
a) Clock Generation :
Crystal Input Clock (TCLK and XTAL). This is the input pair to an internal crystal oscillator and
corresponding logic. A 14.318 MHz crystal is recommended.
b) Hardware Reset ( Pin 5 )
Hardware Reset signal is generated by MAX809 (U10).It assert a reset signal at least 100 ms.
c) Analog to Digital Converter
The gm2120 chip has three ADC's (analog-to-digital converters), one for each color (red, green and blue)
The analog RGB signals are connected to gm2120 as described below
Red + 171
-
n + 1
-
Blue + 1
-
d) OSD :
The gm2120 has a fully programmable ,high-quality OSD controller.The on-chip static RAM(4096 words
by 24 bits) stores the cell map and the cell definitions.
e) On-Chip Microcontroller (OCM)
The gm2120 on-chip microcontroller(OCM) serves as the system microcontroller.That is , it programs the
gm2120 and manages other devices in the system such as the keypad, the backlight, LED, audio and
non-volatile RAM.using general purpose input/output (GPIO) pins.

f) Panel Power Sequencing ( PPWR, PBIAS) ( Pin 113~114)
The gm2120 has two dedicated outputs PPWR and PBIAS ( Pin113 and Pin114) to control LCD power
sequencing once data and control signals are stable.
g) Parallel ROM Interface Port (Pin 8~25, Pin28~35)
The gm2120 has parallel ROM interface port , pin8~25 for address bus, pin28~35 for data bus.
h) Panel interface (Pin 55~66, Pin69~80, Pin83~87, Pin90~96.Pin99~110)
The gm2120 driver interface is highly programmable. It supports dual bus / dual port for SXGA drivers.
1.2 LVDS Transmitter DS90FC383 (U1,U2)
The DS90FC383 transmitter converts 28 bits of TTL data into four LVDS ( Low Voltage Differential
Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams
over a fifth LVDS link. At a transmit clock frequency of 85 MHz, 24 bits of RGB data and 3 bits of LCD
timing and control data ( FPLINE, FPFRAME, DRDY) are transmitted at rate of 595 Mbps per LVDS
data channel. U1 AS the ODD pixel transmitter , U2 as the EVEN pixel transmitter.
