1．Application
This technical literature applies to the color TFT-LCD module LQ121S1LG81.
These technical literature sheets are the proprietary product 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.
The device listed in these technical literature sheets was designed and manufactured for use in general electronic
equipment.
In case of using the device for applications such as control and safety equipment for transportation (controls of
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,
PRELIMINARYtelecommunication 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 which does not comply
with the instructions and the precautions specified in these technical literature sheets.
Contact and consult with a SHARP sales representative for any questions about this device.

・ Hsync/Vsync need not be input so that this model may drive only by the ENAB signal.
Even if Hsync/Vsync is input, it doesn't become a malfunction.
・ The relation between the data input and the backlight lighting will recommend the above-mentioned input sequence.
When the backlight is turned on before the panel operates, there is a possibility of abnormally displaying.
The liquid crystal module is not damaged.
