Transistor). It is composed of a color TFT-LCD panel, driver ICs, PWB. Graphics and texts can be displayed

on a 1366×RGB×768 dots panel with about 16.7M colors (R/G/B 6bits+Hi FRC data in each color) by using

LVDS(Low Voltage Differential Signaling) to interface, +5V of DC supply voltage.

[Note 2] The maximum operating temperature is based on the test condition that the surface temperature of

display area is less than or equal to 50ºC with LCD module alone in a temperature controlled

chamber. Thermal management should be considered in your product design to prevent the surface

temperature of display area from being over 60ºC. The range of operating temperature may degrade

in case of improper thermal management in your product design.

[Note 3] The rating of environment is base on LCD module. Leave LCD cell alone, this environment condition

can’t be guaranteed. Except LCD cell, the customer has to consider the ability of other parts of LCD

module and LCD module process.

※ About the relation between data input and back light lighting, please base on the above-mentioned input

sequence.

※

When back light is switched on before panel operation or after a panel operation stop, it may not display
normally. But this phenomenon is not based on change of an incoming signal, and does not give damage
to a liquid crystal display.

※ VCC-dip conditions:

(1) When 3.6V≦VCC(min)<4.5V, td≦10 ms
(2) When VCC <3.6 V, VCC-dip conditions should also follow the VCC-turn-on conditions.

The contrast ratio is defined as the following.

[Note 3] Definition of response time

The output signals of photo detector are measured when the input signals are changed from “Full White” to
“Full Black” (rising time, Tr), and from “Full Black” to “Full Black” (falling time, Tf), respectively. The response
time is interval between the 10% and 90% (1 frame at 60 Hz) of amplitudes.

9. PRECAUTIONS

（a）Because the Open-Cell is too weak to destroy by static electricity, please don’t touch the terminal with bare

hands.

（b）Front polarizer can easily be damaged. Pay attention on it.
（c）Since long contact with drops of water may cause discoloration or spots, please wipe off them as soon as

possible.

（d）When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
（e）The Panel will be broken or chipped when it is dropped or bumped against a hard substance.
（f）Precautions of peeling off the Protection Film:

*1) Be sure to peel off slowly (recommended more than 7 sec.) and constant speed.
*2) Peeling direction shown in the next Fig.
*3) Be sure to ground person with adequate methods such as the anti-static wrist band.
*4) Be sure to connect PWB to GND while peeling off the protection film.
*5) Ionized air should be blown to the surface while peeling off the protection film.
*6) The protection film must not touch drivers and PWB.

After the protection film has been peeled off, some adhesive may be remained on the polarizer. Please
use isopropyl-alcohol to remove it.

（g）Since the Open-cell consists of TFT and electronic circuits with CMOS-ICs, which are very weak to

electrostatic discharge, persons who are handling an Open-Cell should be grounded though adequate
methods such as an anti-static wrist band. Connector pins should not be touched directly with bare hands.

（h）Avoiding COF damage, do not bend PWB to display side when handling the open cell, recommend coating

silicon or tuffy on front and back side of COF.
Reference: Process control standard of CPL.

（i）Since the Open-cell has a PWB, please take care to keep it off any stress or pressure when handling or

installing the Open-cell, otherwise some of electronic parts on them may be damaged.

（j）Be sure to turn off the power supply when inserting or disconnecting the cable.
（k）Be sure to design the module and cabinet so that the Open-cell van is installed without any extra stress such

as warp or twist.

（l）When handling and assembling Open-Cell into module, please be noted that long-term storage in the

environment of oxidization or deoxidization gas and the use of materials such as reagent, solvent, adhesive,
resin… etc, which generate these gasses, may cause corrosion and discoloration of the Open-Cell.

（m）Applying too much force and stress to PWB and drivers may cause a malfunction electrically and

mechanically.

（n）The Open-cell has high frequency circuits. Sufficient suppression to EMI should be done by system

manufactures.

（o）Please be careful since image retention may occur when a fixed pattern is displayed for a long time.
（p）The chemical compound, which causes the destruction of ozone layer, is not being used.

LC185TT1A Specification Version1.1

（q）This Open-Cell module is corresponded to RoHS.
（r）When any question or issue occurs, it shall be solved by mutual discussion.
