LP201WE1
Liquid Crystal Display
Product Specification
1. General Description
LP201WE1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
2 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 20.1 inch diagonally measured
active display area with WSXGA+ resolution (1050 vertical by 1680 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(True) colors. It has been designed to apply the 8Bit 2 port
LVDS interface. It is intended to support displays where high brightness, wide viewing angle, and high color
are important.
General Features
Active Screen Size 20.1 inches(511.133mm) diagonal (Aspect ratio 16:10)
Outline Dimension 453.5(H) x 296.5 (V) x 8.3(D) mm (Typ.)
Pixel Pitch 0.258mm x 0.258mm
Pixel Format 1680 horiz. by 1050 vert. Pixels RGB strip arrangement
Color Depth 8bit, 16.7M colors
Luminance, White 320 cd/m2 (Typ.) 5 point Avg.
Viewing Angle (CR>10) Viewing Angle R/L 160 (Typ.), U/D 140 (Typ)
Power Consumption 15.6Watt(Typ.) (Circuit: 4.3Watt@Black, B/L: 11.3Watt @each Lamp=7.5mA)
Weight 1220g Max
Display Operating Mode Transmissive mode, normally White
Surface Treatment Hard coating & Glare (2H) treatment of the front polarizer

3. Electrical Specifications
3-1. Electrical Characteristics
The LP201WE1(TLA1)requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an
inverter. The inverter is an external unit to the LCD.

Note)
1. The specified current and power consumption are under the VCC = 5.0V , 25 , fv = 60Hz condition
whereas Black pattern is displayed and fv is the frame frequency.
2. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.
3. The variance of the voltage is 10%.
4. The typical operating current is for the typical surface luminance (LWH) in optical characteristics.
5. Define the brightness of the lamp after being lighted for 5 minutes as 100%, Ts is the time required for
the brightness of the center of the lamp to be not less than 95%.
6. The life time is determined as the time at which brightness of lamp is 50% compare to that of initial value
at the typical lamp current.
7. The output of the inverter must have symmetrical(negative and positive) voltage waveform and
symmetrical current waveform.(Asymmetrical ratio is less than 10%) Please do not use the inverter
which has asymmetrical voltage and asymmetrical current and spike wave.
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.
8. The voltage above VS should be applied to the lamps for more than 1 second for start-up. Otherwise, the
lamps may not be turned on. The used lamp current is the lamp typical current.
9. The lamp power consumption shown above does not include loss of external inverter.
The applied lamp current is a typical one.

10. 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.
* Asymmetry rate:
