1. Application
This specification applies to the color 31.5" TFT-LCD module LQ315D1LG91.
* These specification sheets 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.

2. Overview
This module is a color active matrix LCD module. It is composed of a color TFT-LCD panel, driver ICs, control
circuit, power supply circuit, and back light system etc. Graphics and texts can be displayed on a 3840 x RGB x
2160 (QFHD) dots panel with about one billion colors by using LVDS (Low Voltage Differential Signaling) to
interface, +12V of DC supply voltages.
This module also includes the LED PWB and LED DRIVER PWB to drive the LED.
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 LCD module 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.
