6.2 Circuit Operation Theory
I. Introduction
The X203H is a 20” W (1600x900), LCD type is TN+Film and Normally White, 16.7M colors(R, G, B 6bit data + Hi-FRC data) TFT LCD with HDCP support monitor. It’s have dual (D-SUB and DVI)
interface LCD monitor with a 15 pins D-sub signal cable and 24 pin DVI signal cable which support
HDCP function. It’s compliant with VESA specification to offer a smart power management and power
saving function. It also offers OSD menu for users to control the adjustable items and get some
information about this monitor. The best function is to offer users an easy method to change input
source, DDC/CI Enable and Auto Adjustment items well done just by pressing hot key, we called it
“Input Select”, “DDC/CI” and “Auto” which can manual controlled items.
X203H also offer DDC/CI function to meet VESA standard.
II. Block diagram

(a) Circuit operations:
A basic operation theory for this interface board is to convert analog signals of Red, Green
and Blue to digital signals of Red, Green and Blue. The scaling IC has internal A/D converter,
internal OSD, built in LVDS transmitter and auto-detect input timing functions. A/D converter
is convert analog signal to digital data. OSD is offering adjustable functions to end-user.
Detect timing is for detect change mode. LVDS transmitter is used to compress the digital
RGB data, the Hsync, Vsync and pixel clock generated by Scaling then output to LCD
module. MCU stores source code and offers H/W DDC2Bi function & controls system
processing. EEPROM is stored DDC and HDCP data, OSD common data and user mode
data.
(b) IC introduction:
1.) DDC (Display Data Channel) function: We use DDC IC to support DDC2Bi function. DDC
data is store in 24C02 (EEPROM). Those data related to LCD monitor specification. PC
can read them by “SDA” and “SCL” serial communication for I²C communication for
DDC2Bi.
2.) Scalar IC: There are A/D, TMDS receiver, HDCP, Scaling, OSD and LVDS transmitter
functions built-in the RTD2545LH IC. Scaling IC is revolutionary scaling and color engine,
- 58 -
capable of expanding any source resolution to a highly uniform and sharp image or down
scaling from 1980x1020, combined with the critically proven integrated 8 bit triple-ADC
and patented Rapid-lock digital clock recovery system. It also support detect mode and
DPMS control.
3.) RTD2120L: Control unit, it controls all the functions of this interface board, just like the
OSD display setting, the adjustable items, adjusted data storage, the external IIC
communication, support DDC2Bi. .
4.) EEPROM: We use 24C016 to store all the adjustable data, user settings and HDCP Key
and use 2 of 24C02 to store DVI and D-SUB EDID data.
A-2.) Control board introduction :
There are 6 keys for user'
s control which includes “Menu”, “Right”, “Left”, “Auto”,
“Empowering”, and “Power”. The following descriptions are the introduction of these keys.
(1) “Menu” key: to enter sub-menus or select items.
(2) “Right” key: to select previous and to increase adjustment
(3) “Left” key: to select next and to decrease adjustment
(4) “Auto” key: to perform auto adjustment and Exit key
(5) “Empowering”: to Open the Acer eColor Management OSD and access the scenario
modes
(6) “Power” key: to turn/off power of monitor
(7) LED: It indicates the DPMS status of this LCD monitor; green light means DPMS on
(Normal operating condition). Amber light means DPMS off (Power Saving).
