1. General Description

LC470WUF is a Color Active Matrix Liquid Crystal Display with an 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. It has a 46.96 inch diagonally measured active display area with WUXGA resolution (1080 vertical by 1920 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 luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot, thus presenting a palette of more than 1.06Billion(FRC) of colors. It has been designed to apply the 10-bit 4 port LVDS interface. It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut, high color depth and fast moving picture response time are important.

Note : The design of the inverter must have specifications for the lamp in LCD Assembly.

The electrical characteristics of inverter are based on High-High Driving type.

The performance of the lamps 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) has never been occurred. When you confirm it,

the LCD– Assembly should be operated in the same condition as installed in your instrument.

୔ Do not attach a conductive tape to lamp connecting wire.

If you attach conductive tape to the lamp wire, not only luminance level can be lower than typical one but also inverter operate abnormally on account of leakage current which is generated between lamp wire and conductive tape.

1. Specified values are defined for a Backlight Assembly.( IBL : 22 lamp, 7mA/Lamp)

2. Operating voltage is measured at 25 r 2¶C(after 2hr.aging). The variance range for operating voltage is r 10%.

] should be applied to the lamps for more than Striking time (S

3. The established starting voltage [

for start-up. Inverter open voltage must be more than established starting voltage. Otherwise, the lamps may not be turned on. The used lamp current is typical value.

4. Lamp frequency may produce interference with horizontal synchronous frequency. As a result, the may cause beat on the display. Therefore, lamp frequency shall be away as much as possible from the horizontal

synchronous frequency and its harmonics range in order to prevent interference.

5. The brightness of the lamp after lighted for 5minutes is defined as 100%.

is the time required for the brightness of the center of the lamp to be not less than 95% at typical current.

The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on.

6. Maximum level of power consumption is measured at initial turn on. Typical level of power consumption is measured after 2hrs aging at 25 r 2¶C.

7. The life time 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 r 2¶C, based on duty 100%.

8.The output of the inverter must have symmetrical(negative and positive) voltage and current waveform

(Unsymmetrical ratio is less than 10%). Please do not use the inverter which has not only unsymmetrical

voltage and current but also spike wave. Requirements for a system inverter design, which is intended to achieve better display performance,

power efficiency and more reliable lamp characteristics. It can 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:

୔ We recommend not to be much different between PWM duty and Iout duty . ୔ Minimum PWM duty ratio should be defined based on the minimum luminance. ୔ Dimming current output rising and falling time may produce humming and inverter trans’ sound noise. ୔ Burst dimming duty should be 100% for more than 1second after turn on. ୔ Equipment
