1. Precautions and Safety Notices

1. Appropriate Operation

(1) Turn off the product before cleaning.

(2) Use only a dry soft cloth when cleaning the LCD panel surface.

(3) Use a soft cloth soaked with mild detergent to clean the display housing.

(4) Use only a high quality, safety approved AC/DC power cord.

(5) Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.

(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.

(7) Do not touch the LCD panel surface with sharp or hard objects.

(8) Do not place heavy objects on the LCD display, video cable, or power cord.

(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.

(10) Do not operate the product under the following conditions:

- Extremely hot, cold or humid environment.

- Areas containing excessive dust and dirt.

- Near any appliance generating a strong magnetic field.

- In direct sunlight.

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

Connector of the TFT Module.

(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.

Main Menu Controls

Adjust the menu items shown below by using the upSand downTbuttons.

Control Explanation

Auto Image Adjust automatically sizes, centers, and fine tunes the video signal to eliminate waviness and distortion.

NOTE:

1. Auto Image Adjust works with most common video cards. If this function

does not work on your LCD display, then lower the video refresh rate to 60 Hz and set the resolution to its pre-set value.

2. The Auto Image Adjust and most Manual Image Adjust functions are not available for DVI input.

Contrast adjusts the difference between the image background (black level) and the foreground (white level).

Brightness adjusts background black level of the screen image.

Input Select allows you to toggle between an analog and a digital signal.

Color Adjust provides several color adjustment modes: preset color

temperatures and User Color which allows you to adjust red (R), green (G), and blue (B) separately. The factory setting for this product is 6500K (6500 Kelvin).

sRGB-sRGB is quickly becoming the industry standard for color management, with support being included in many of the latest applications. Enabling this setting allows the LCD display to more accurately display colors the way they were originally intended. Enabling the sRGB setting will cause the Contrast and Brightness adjustments to be disabled.

9300K-Adds blue to the screen image for cooler white (used in most office settings with fluorescent lighting).

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.

VX922-1

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.

Pin number Pin Name Pin Usage

1 P5.2 Key / Power on, off

13 P3.4 NV_RAM (U4) SDA

14 P3.5 NV_RAM (U4) SCL

41 P5.4 Key_down

40 P5.5 Key_right

42 P5.3 Key_up

34 P5.6 Key_left

9 P6.3 Key_mute

2 P5.1 Key_select

27 P6.0 LED_red

26 P6.1 LED_green

16 P6.2 LCD panel power1 on / off control

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 drivers.

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.
