2. Overview
This Open-Cell is a color active matrix LCD module incorporating amorphous silicon TFT (T
It is composed of a color TFT-LCD panel, driver ICs, control circuit, power supply circuit, inverter circuit and back
light system etc. Graphics and texts can be displayed on a 1366×RGB×768 dots panel with 16,777,216 colors by
using LVDS (L
And in order to improve the response time of LCD, this module 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.
By using the captioned process, the image signals of this Open-Cell are being set so that image response can be
completed within one frame, as a result, image blur can be improved and clear image performance can be realized.

14. P
a) Because the Open-Cell is weak to static electricity, please do not touch the terminal with bare hands.
b) Since the front polarizer is easily damaged, pay attention not to scratch it.
c) Since long contact with drops of water may cause discoloration or spots, please wipe off them as soon as put
on the screen.
d) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
e) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with
care.
f) Precautions of peeling off the protection film:
- Be sure to peel off slowly (recommended more than 7sec) and constant speed.
- Peeling direction shown in Fig. 5.
- Be sure to ground person with adequate methods such as the anti-static wrist band.
- Be sure to ground S-PWBs while peeling off the protection film.
- Ionized air should be blown to the surface while peeling off.
- The protection film must not touch drivers and S-PWBs.
- If adhesive may remain on the polarizer after the protection film peeled off, please remove with
isopropyl-alcohol.
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 a Open-Cell should be grounded through adequate methods
such as an anti-static wrist band. Connector pins should not be touched directly with bare hands.
㺃 Reference: Process control standard of sharp

LD-K24Z13C-15
h) Since the Open-Cell has some PWBs, please take care to keep them off any stress or pressure when handling
or installing the Open-Cell, otherwise some of electronic parts on them may be damaged.
i) Be sure to turn off the power supply when inserting or disconnecting the cable.
j) 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.
One step solution for LCD / PDP / OLED panel application: Datasheet, inventory and accessory!
www.panelook.com
Global LCD Panel Exchange Center
k) When handling and assembling Open-Cells into module and cabinets, 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.
l) Applying too much force and stress to PWBs and drivers may cause a malfunction electrically and
mechanically.
m) The Open-Cell has high frequency circuits. Sufficient suppression to EMI should be done by system
manufactures.
n) Please be careful since image retention may occur when a fixed pattern is displayed for a long time.
o) The chemical compound, which causes the destruction of ozone layer, is not being used.
p) This Open-Cell module is corresponded to RoHS.
q) Please design the heat dissipation of the module with enough care for SC-PWB, Source-driver
and Gate-driver’s IC.
r) When any question or issue occurs, it shall be solved by mutual discussion.
