1. OVERVIEW 

CL A AMO WA 0 1 A (with LVDS interface) is 14" color TFT-LCD (Thin Film Transistor 
Liquid Crystal Display) module composed of LCD panel , driver ICs , control circuit , and 
backlight. 

By applying 6 bits digital data, 1280x768, 262K color images are displayed on the 14" 
diagonal screen. Input power voltage is single 3.3V for LCD driving. 


Inverter for backlight is not included in this module. General specifications are 
summarized in the following table:

Standard inverter : HIU766(52k) , typical luminance = (185) cd/m (5 point). 
The time that module luminance reduced to 50% of initial value . 

Base on Vs = (1420) V , Ta = 25°C, IL=6.0 mA continuous. 



The lamp shall be stably lighted. Slide up method shall be used for 
input voltage application. The voltage is applied voltage to both ends 
of the lamp as the established starting voltage.

[Note 2] 


Lamp frequency of inverter may produce interference with horizontal synchronous 
frequency, and this may cause horizontal beat on the display. Therefore, please 
adjust lamp frequency, and keep inverter as far from module as possible or use 
electronic shielding between inverter and module to avoid the interference. 

The degrees of unbalance: less than 10% 

The ratio of wave height: less than 2 ±10% 



Ip 


I-P 


The degrees of umbalance = Ip-I-p /Irms* 100(%) 

The ratio of wave height = Ip(or I-p)/Irms 

Ip: lamp current high side peak, I-p: lamp current low side peak

Fail: No display image, obvious non-uniformity, or line defects. 

10. HANDLING PRECAUTIONS FOR TFT-LCD MODULE 

Please pay attention to the followings in handling- TFT-LCD products: 

(A) ASSEMBLY PRECAUTION 

(1) Please use the mounting hole on the module side in installing and do not beading or 

wrenching LCD in assembling. And please do not drop, bend or twist LCD module in 

handling. 

(2) Please design display housing in accordance with the following guidelines. 

(2.1) Housing case must be destined carefully so as not to put stresses on LCD all sides 
and not to wrench module. The stresses may cause non-uniformity even if there is 
no non-uniformity statically. 

(2.2) Keep sufficient clearance between LCD module back surface and housing when 
the LCD module is mounted. Approximately 1.0 mm of the clearance in the 
design is recommended taking into account the tolerance of LCD module 
thickness and mounting structure height on the housing. 

(2.3) When some parts, such as, FPC cable and ferrite plate, are installed underneath 
the LCD module, still sufficient clearance is required, such as 0.5mm. This 
clearance is, especially, to be reconsidered when the additional parts are 
implemented for EMI countermeasure. 

(2.4) Design the inverter location and connector position carefully so as not to give 
stress to lamp cable, or not to interface the LCD module by the lamp cable. 

(2.5) Keep sufficient clearance between LCD module and the others parts, such as 
inverter and speaker so as not to interface the LCD module. Approximately 
1.0mm of the clearance in the design is recommended. 

(3) Please do not push or scratch LCD panel surface with any-thing hard. And do not soil 
LCD panel surface by touching with bare hands. (Polarizer film, surface of LCD panel 
is easy to be flawed.) 

(4) Please do not press any parts on the rear side such as source TCP, gate TCP, control 
circuit board and FPCs during handling LCD module. If pressing rear part is 
unavoidable, handle the LCD module with care not to damage them. 

(5) Please wipe out LCD panel surface with absorbent cotton or soft of cloth in case of it 
being soiled. 

(6) Please wipe out drops of adhesives like saliva and water on LCD panel surface 
immediately. They might damage to cause panel surface variation and color change. 

(7) Please do not take a LCD module to pieces and reconstruct it. Resolving and 
reconstructing modules may cause them not to work well. 

(8) Please do not touch metal frames with bare hands and soiled gloves. A color change of 
the metal frames can happen during a long preservation of soiled LCD modules. 

(9) Please pay attention to handling lead wire of backlight so that it is not tugged in 
connecting wit inverter. 

(B) OPERATING PRECAUTIONS 

(1) Please be sure to turn off the power supply before connecting and disconnecting signal 
input cable. 

(2) Please do not change variable resistance settings in LCD module. They are adjusted to 
the most suitable value. If they are changed, it might happen LCD does not satisfy the 
characteristics specification. 

(3) Please consider that LCD backlight takes longer time to become stable of radiation 
characteristics in low temperature than in room temperature. 

(4) A condensation might happen on the surface and inside of LCD module in case of

sudden charge of ambient temperature. 

(5) Please pay attention to displaying the same pattern for very long time. Image might 
stick on LCD. 

(6) Please obey the same caution descriptions as ones that need to pay attention to ordinary 
electronic parts. 

(C) PRECAUTFONS WITHELECTROSTATICS 

(1) This LCD module use CMOS-IC on circuit board and TFT-LCD panel, and so it is 
easy to be affected by electrostatics. Please be careful with electrostatics by the way of 
your body connecting to the ground and so on. 

(2) Please remove protection film very slowly on the surface of LCD module to prevent 
from electrostatics occurrence. 

(D) STORAGE PRECAUTIONS 

(1) When you store LCDs for a long time, it is recommended to keep the temperature 
between 0°C-40°C without the exposure of sunlight and to keep the humidity less than 
90%RH. 

(2) Please do not leave the LCDs in the environment of high humidity and high 
temperature such as 60°C 90%RH. 

(3) Please do not leave the LCDs in the environment of low temperature below -20°C. 

(E) SAFETY PRECAUTIONS 

(1) When you waste LCDS, it is recommended to crush damaged or unnecessary LCDs 
into pieces and wash them off with solvents such as acetone and ethanol, which should 
later be burned. 

(2) If any liquid leaks out of a damaged-glass cell and comes in contact with the hands, 
wash off throughly with soap and water. 

(F) OTHERS 

(1) A strong incident light into LCD panel might cause display characteristics' changing 
inferior because of polarizer film, color filter, and other materials becoming inferior. 
Please do not expose LCD module direct sunlight Land strong UY rays. 

(2) Please pay attention to a panel side of LCD module not to contact with other materials 
in preserving it alone. 

(3) For the packaging box, please pay attention to the followings: 

(3.1) Packaging box and inner case for LCD are designed to protect the LCDs from the 
damage or scratching during transportation. Please do not open except picking 
LCDs up from the box. 

(3.2) Please do not pile them up more than 5 boxes. (They are not designed so.) And 
please do not turn over. 

(3.3) Please handle packaging box with care not to give them sudden shock and 
vibrations. And also please do not throw them up. 

(3.4) Packing box and inner case for LCDs are made of cardboard. So please pay 
attention not to get them wet. (Such like keeping them in high humidity or wet 
place can occur getting them wet.)
