protected under copyright of SHARP. Do not reproduce or cause any third party to reproduce them in any form or
by any means, electronic or mechanical, for any purpose, in whole or in part, without the express written
permission of SHARP.

* In case of using the device for applications such as control and safety equipment for transportation (aircraft, trains,

automobiles, etc.), rescue and security equipment and various safety related equipment which require higher
reliability and safety, take into consideration that appropriate measures such as fail-safe functions and redundant
system design should be taken.

* Do not use the device for equipment that requires an extreme level of reliability, such as aerospace applications,

telecommunication equipment (trunk lines), nuclear power control equipment and medical or other equipment for
life support.

* SHARP assumes no responsibility for any damage resulting from the use of the device that does not comply with

the instructions and the precautions specified in these specification.

* Contact and consult with a SHARP sales representative for any questions about this device.

2 Overview

This Open Cell (LK400D3HC75) is a color active matrix LCD PANEL incorporating amorphous silicon TFT (Thin
Film Transistor), polarizers, Control-PWB(C-PWB), Source-PWBs, Source-Drivers, Gate-Drivers and FPCs. The
following content can be achieved in using C-PWB (LK0DZ1C0539) that SHARP specifies.

Graphics and texts can be displayed on a 1920×RGB×1080 dots panel with one billion colors by using 10bit
LVDS (Low Voltage Differential Signaling) to interface, +12V of DC supply voltages.

In order to improve the response time of LCD, This C-PWB applies the Over Shoot driving (O/S driving)
technology for the control circuit. In the O/S driving technology, signals are being applied to the Liquid Crystal
according to a pre-fixed process as an image signal of the present frame when a difference is found between image
signal of the previous frame and that of the current frame after comparing them.

With combination of these technologies, motion blur can be reduced and clearer display performance can be
realized.

[Caution] You should design thermal conductive interface pad and C-PWB cover enough to radiate heat from T-CON
IC in C-PWB.

※ About the relation between data input and back light lighting, we recommend the above-mentioned input

sequence. If the back light is switched on before a panel operation begins or after a panel operation stops,
the screen may not be displayed properly. But this phenomenon is not caused by change of an incoming
signal, and does not give damage to a liquid crystal display.

13 Precautions

a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) Be sure to design the cabinet so that the Open Cell can be installed without any extra stress such as warp or

twist.

c) Since the polarizer is easily damaged, pay attention not to scratch it.
d) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
e) When the polarizer is soiled, wipe it with absorbent cotton or other soft cloth.
f) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with

care.

g) Precautions of peeling off the protection film.

- Be sure to peel off slowly (recommended more than 7sec) and constant speed.

- Peeling direction shows below Fig.5.

- Be sure to ground person with adequate methods such as the anti-static wrist band.

- Be sure to ground S-PWB while peeling of the protection film.

- Ionized air should be blown over during peeling action.

- The protection film must not touch drivers and S-PWBs.

- If adhesive may remain on the polarizer after the protection film peeling off,
please remove with isopropyl-alcohol.

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

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

i) The Open Cell has some PWBs, take care to prevent them from any stress or pressure when handling or

installing the Open Cell, otherwise some of electronic parts on the PWBs 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 can be installed without any extra stress

such as warp or twist.

l) When handling the Open Cell and assembling them into module and cabinets, please be noted that

long-term storage in the environment of oxidization or deoxidization gas and the use of such materials 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 driver may cause a malfunction electrically and

mechanically.

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

manufacturers.

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 used.
q) Please design the heat dissipation of the module with enough care for C-PWB, Source-Driver and

Gate-Driver’ IC.

r) This Open Cell is corresponded to RoHS. ‘‘R.C.’’ label on the side of palette shows it.

s) When any question or issue occurs, it shall be solved by mutual discussion.
