1 Application
This specification applies to the color 40.0" TFT-LCD Open Cell LK400D3HA
With parts (FPC,C-PWB) to drive it.
* These specification are proprietary products of SHARP CORPORATION ("SHARP") and include materials
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 is a color active matrix LCD Open-Cell incorporating amorphous silicon TFT (Thin Film Transistor).
It is composed of a color TFT-LCD panel, driver ICs and Source PWB. The following content can be achieved in
using LK0DZ1C0 (CONTROL PWB C-PWB ) and LK0DZ1C0112 (FPC) 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.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.
And 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.
