2. Caution

No modification of any circuit should be attempted. Service work should only be performed after you are thoroughly familiar

with all of the following safety checks and servicing guidelines.

3. Safety Check

Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit, the voltage is

exposed in such areas as the associated transformer circuits.

4. LCD Module Handling Precautions

4.1 Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when connecting or disconnecting input connector.
(3) Wipe off water drops immediately. Long contact with water may cause discoloration or spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and ensure human earth when handling.
(7) Do not open or modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module in any direction.
(9) In the event that a Module must be put back into the packing container slot after it was taken out of the

container, do not press the center of the CCFL Reflector edge. Instead, press at the far ends of the
CFL Reflector edge softly. Otherwise the TFT Module may be damaged.

(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate or tilt the Interface

(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist or

bend the TFT Module even momentarily. When designing the enclosure, it should be taken into consideration
that no bending/twisting forces may be applied to the TFT Module from outside. Otherwise the TFT Module
may be damaged.

(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local

ordinances or regulations for disposal.

(13) The LCD module contains a small amount of materials having no flammability grade. The LCD module

should be supplied with power that complies with the requirements of Limited Power Source
(IEC60950 or UL1950), or an exemption should be applied for.

(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950

or UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit.

6. THEORY OF OPERATION

This section describes the function of the LCD monitor per functional block.
This monitor includes MB board, power board and button board.

6.1 MB BOARD
The MB board is a two-layer, single-grounded design with ground and internal planes provided. DC power from

the power board enters the board through a 6P connector. The other connector on the board is for the button board.

The VGA cable is a signal cable that carries the video, sync and DDC signals from the PC VGA adapter. This

system board consists of 4 functional areas: flat panel controller, MCU with flash ROM, and power regulators.

6.1.1 Flat panel controller: RTD2523(U7)

The heart of the system board is the Realtek RTD2523. The RTD2523 is a graphics processing IC
designed for LCD monitors. It provides all key IC functions required for LCD displays. On-chip
functions include a high-speed triple-ADC, PLL, high scaling engine and OSD controller.

a) Clock Generation:

Crystal Input Clock (TCLK and XTAL). This is the input pair to an internal crystal oscillator and

corresponding logic. A 24.576 MHz crystal is recommended.

b) Analog to Digital Converter:

The RTD2523 chip has three ADCs (analog-to-digital converters), one for each color (red, green and blue).
The analog RGB signals are connected to RTD2523 as described below.

Pin Name Pin Number
Red + 37
Red - 38
Green + 34
Green - 35
Blue + 30

Blue - 31

c) OSD: The RTD2523 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.

17 P1.0 Backlight on / off control

e) Panel Power Sequencing (PANEL_PW12,3) (Pin 16, 18): The MTV312 has two dedicated outputs

VDDCTRL1 and 2 ( Pin32 and Pin3) to control LCD power sequencing once data and control signals

are stable.

f) Panel interface (Pin73~94): The RTD2523 driver interface is highly programmable. It supports dual bus /

dual port for SXGA drive rs.

6.1.2 Power Regulator AIC1563 (U2), AIC1117CY (U1,U3): The AIC1563 is a monolithic control IC
containing the primary functions required for DC to DC converters. The device consists of an internal temperature

compensated reference, a comparator, and a controlled duty cycle oscillator with an active current
sense circuit. The desired output voltage is determined by the equation, Volt = 1.25 (1 + R11 / R12).
In this case, the output voltage is 5 Volts. The AIC1563 is a low dropout positive adjustable
regulator with minimum of 1A output current capability, so it is well suited to serve as a 3.3 V or

2.5 V regulator.

6.1.3 Power Regulator AIC1117CY (U1,U3): The AIC1117CY is a monolithic control IC containing the
primary functions required for DC to DC converters. The device consists of an internal temperature
compensated reference, a comparator, and a controlled duty cycle oscillator with an active current
sense circuit. The desired output voltage is determined by the equation, Volt = 1.25 (1 + R17 / R15).
In this case, the output voltage is 2.5 Volts for panel power.

d) MTV312 Micro Controller: The MTV312 micro controller (MCU) serves as the system micro controller.

It programs the RTD2523 and manages other devices in the system such as the keypad, the backlight, the
LED, the audio system and the non-volatile RAM using general purpose input/output (GPIO) pins.
