1. General Description
The LM201U05-SLA1 s 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 black mode. This TFT-LCD has a 20.1 inch diagonally measured active display area with UXGA resolution(1200 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 16,777,216 colors. 
The LM201U05-SLA1 has been designed to apply the interface method that enables low power, high speed,low EMI. FPD Link must be used as a LVDS(Low Voltage Differential Signaling) chip. 
The LM201U05-SLA1 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 LM201U05-SLA1 characteristics provide an excellent flat panel display for office automation products such as monitors.

3. Electrical Specifications
3-1. Electrical Characteristics
The LM201U05-SLA1requires 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.

Notes :1. The specified current and power consumption are under the VCC=18.0V, 25 C, fV=60Hz condition, Typical supply current is measured at the condition of 8 X 6 chess pattern (white black)
and Max supply current
is measured at the sub 1dot pattern.
2.This impedance value is for impedance matching between LVDS TX and the mating connector of the LCD.
3.The duration of rush current is about 1ms.
4.Operating voltage is measured at 25 C. The variance of the voltage is 10%.
5.The output voltage at the transformer in the inverter must be high considering to the loss of the
ballast capacitor in the inverter. 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.
6. 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.
7.The lamp power consumption shown above does not include loss of external inverter at 25 C. The used lamp current is the lamp typical current.
8.Let’s 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%. The used lamp current is the lamp typical current.
9.The life time is defined as the time at which brightness of lamp is 50% compare to that of initial value at the typical lamp current on condition of continuous operating at 25 2 C.

LM201U05
Liquid Crystal Display
Product Specification
Note. Do not attach a conducting tape to 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.
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.
Requirements for a system inverter design, which is intended to have a better display performance, a better power efficiency and a more reliable lamp. 
It shall help increase the lamp lifetime and reduce its leakage
current.
a.The asymmetry rate of the inverter current and voltage waveform should be 10% below;
b.The distortion rate of the current and voltage waveform should be within 2 10%;
c.The ideal sine current and voltage waveform shall be symmetric in positive and negative polarities.
I p |
I -p |
* Asymmetry rate = 
| I p – I –p | / Irms * 100%
* Distortion rate = I p (or I –p) / Irms
