LC420DUJ
Product Specification
1. General Description
The LC420DUJ is a Color Active Matrix Liquid Crystal Display with an integral the Source PCB and Gate
implanted on Panel (GIP). 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 41.92 inch diagonally measured
active display area with WUXGA resolution (1080 vertical by 1920horizontal 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 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7M(true) colors.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

notes:1. The input of HSYNC & VSYNC signal does not have an effect on normal operation (DE Only Mode).
If you use spread spectrum of EMI, add some additional clock to minimum value for clock margin.
2. The performance of the electro-optical characteristics may be influenced by variance of the vertical
refresh rate and the horizontal frequency
3. Spread Spectrum Rate (SSR) for 50KHz ~ 100kHz Modulation Frequency(FMOD) is calculated by
(7 – 0.06*Fmod), where Modulation Frequency (FMOD) unit is KHz.
LVDS Receiver Spread spectrum Clock is defined asbelow figure

3-6. Color Data Reference
The brightness of each primary color(red,green,blue) is based onthe 8bit gray scale data input for the color.
The higher binary input, the brighter the color. Table 6 provides a reference for color versus data input.
1. Even though T1 is over the specified value, there is no problem if I2T spec of fuse is satisfied.
2. If T2 is satisfied with specification after removing LVDS Cable, there is no problem.
3. The T3 / T4is recommended value, the case when failed to meet a minimum specification,
abnormal display would be shown. There is no reliability problem.
4. T5 should be measured after the Module has been fully discharged between power off and on period.
5. If the on time of signals (Interface signal and user control signals) precedes the on time of Power (V
it will be happened abnormal display. When T6is NC status,T6 doesn’t need to be measured.
6. It is recommendation specification that T7 has to be 0ms as a minimum value.
※ Please avoid floating state of interface signal at invalid period.
※ When the power supply for LCD (VLCD) is off, be sure to pull down the valid and invalid data to 0V.

10. Precautions
Please pay attention to the followings when you use this TFT LCDmodule.
10-1. Handling Precautions
(1) Please attach the surface transparent protective film to thesurface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to the resist external force.
(2) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break
by electro-chemical reaction.
(3) Do not touch, push or rub the exposed polarizers with glass,tweezers or anything harder than HB
pencil lead. And please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental
to the polarizer.)
(4) After removing the protective film,when the surface becomes dusty, please wipe gently with absorbent
cotton or other soft materials like chamois soaks with petroleum benzine.
Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer.
(5) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and color fading.
(6) Since a module is composed of electronic circuits, it is notstrong to electrostatic discharge.
Make certain that treatment persons are connected to ground through wrist band etc. And don’t touch
interface pin directly. Panel ground path should be connected to metal ground.
(7) Please make sure to avoid external forces applied to the Source PCB and D-IC during the process of
handling or assembling the TV set. If not, It causes paneldamage or malfunction.
(8) Panel and BLU should be protected from the static electricity. If not, it causes IC damage.
(9) Do not pull or fold the source D-IC which connect the source PCB and the panel.
(10) Panel(board ass’y) should be put on the BLU structure precisely to avoid mechanical impact.
(11) FFC Cable should be connected between System board and Source PCB correctly.
(12) Mechanical structure for backlight system should be designed for sustaining board ass’y safely.
(13) Surface temperature of the Source D-IC should be controlled under 100℃ with TV Set status.
If not, problems such as IC damage or decrease of lifetime could occur.
10-2. Operating Precautions
(1) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(2) Brightness depends on the temperature. (In lower temperature, it becomes lower.)
And in lower temperature, Stable time(required time thatbrightness is stable after turned on)
becomes longer
(3) Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or
electrical contacted parts. And after fading condensation, smear or spot will occur.
(4) When fixed patterns are displayed for a long time, remnantimage is likely to occur.
(5) Module has high frequency circuits. Sufficient suppressionto the electromagnetic interference shall be
done by system manufacturers. Grounding and shielding methods may be important to minimized the
interference.

10-3. Protection Film
peeling direction
(1) Please keep attaching the protection film before assembly.
(2) Please peel off the protection film slowly.
(3) Please peel off the protection film just like shown in the Fig.1
(4) Ionized air should be blown over during the peeling.
(5) Source PCB should be connected to the ground when peel off the protection film.
(6) The protection film should not be contacted to the source D-IC during peeling it off.
< Fig. 1 >
10-4. Storage Precautions
When storing modules as spares for a long time, the following precautions are necessary.
(1) Temperature : 5 ~ 40 ℃
(2) Humidity : 35 ~ 75 %RH
(3) Period : 6 months
(4) Control of ventilation and temperature is necessary.
(5) Please make sure to protect the product from strong light exposure, water or moisture. Be careful for
condensation.
(6) Please keep the modules at a circumstance shown below Fig. 2
