Liquid Crystal Display
Product Specification
1. General description
LM200WD1-TLD2 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode
Fluorescent Lamp(CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the
active element. It is a transmissive type display operating in the normally white mode. It has a
20.0 inch diagonally measured active display area with HD+ resolution (900 vertical by 1600
horizontal pixel array) Each pixel is divided into Red, Green and Blue sub-pixels or dots which are
arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with
a 8-bit gray scale signal for each dot, thus, presenting a palette of more than 16.7M colors with
Advanced-FRC(Frame Rate Control). It has been designed to apply the interface method that
enables low power, high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low
Voltage Differential Signaling) chip. It is intended to support applications where thin thickness,
wide viewing angle, low power are critical factors and graphic displays are important. In
combination with the vertical arrangement of the sub-pixels, the LM200WD1-TLD2 characteristics
provide an excellent flat panel display for office automation products such as monitors.

3. Electrical specifications
3-1. Electrical characteristics
It requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input power for the CCFL/Backlight, is typically
generated by an inverter. The inverter is an external unit to the LCDs.

Note : The design of the inverter must have specifications for the lamp in LCD Assembly.
The performance of the Lamp in LCM, for example life time or brightness, is extremely
influenced by the characteristics of the DC-AC inverter. So all the parameters of an inverter
should be carefully designed so as not to produce too much leakage current from high-voltage
output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the
mismatch of the lamp and the inverter (no lighting, flicker, etc) never occurs. When you confirm
it, the LCD–Assembly should be operated in the same condition as installed in you instrument.
Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to a
conducting tape,TFT-LCD Module has a low luminance and the inverter has abnormal action.
Because leakage current is occurred between lamp wire and conducting tape.
1. Specified values are for a single lamp.
2. Operating voltage is measured at 25 ± 2C, and follows as below condition.
1) ± 10%@typical operating voltage is based on single lamp.
2) ± 20%@typical operating voltage is based on system & test equipment tolerance.
3. The voltage above V
should be applied to the lamps for more than 1 second for start-up.
S
(Inverter open voltage must be more than lamp starting voltage.)
Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.
4. Lamp frequency may produce interface with horizontal synchronous frequency and as a
result this may cause beat on the display. Therefore lamp frequency shall be as away
possible from the horizontal synchronous frequency and from its harmonics in order to
prevent interference.
5. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
T
is the time required for the brightness of the center of the lamp to be not less than 95%.
S
6. The lamp power consumption shown above does not include loss of external inverter.
The used lamp current is the lamp typical current. (P
= VBLx IBLx N
BL
Lamp
)
7. The life is determined as the time at which brightness of the lamp is 50% compared to that
of initial value at the typical lamp current on condition of continuous operating at 25 ± 2C.

Note :
8. The output of the inverter must have symmetrical(negative and positive) voltage
waveform and symmetrical current waveform (Unsymmetrical ratio is less than 10%).
Please do not use the inverter which has unsymmetrical voltage and unsymmetrical
current and spike wave. Requirements for a system inverter design, which is intended to
have a better display performance, a better power efficiency and a more reliable lamp,
are following.It shall help increase the lamp lifetime and reduce leakage current.
a. The asymmetry rate of the inverter waveform should be less than 10%.
b. The distortion rate of the waveform should be within 2 10%.
* Inverter output waveform had better be more similar to ideal sine wave.

9. The inverter which is combined with this LCM, is highly recommended to connect
coupling(ballast) condenser at the high voltage output side. When you use the inverter
which has not coupling(ballast) condenser, it may cause abnormal lamp lighting because
of biased mercury as time goes.
10.In case of edgy type back light with over 2 parallel lamps, input current and voltage
wave form should be synchronized
