Caution

1. This Kyocera LCD module has been specifically designed for use only
in electronic devices in the areas of audio control, office automation,
industrial control, home appliances, etc. The modules should not be
used in applications where module failure could result in physical harm
or loss of life, and Kyocera expressly disclaims any and all liability
relating in any way to the use of the module in such applications.

2. Customer agrees to indemnify, defend and hold Kyocera harmless from
and against any and all actions, claims, losses, damages, liabilities,
awards, costs, and expenses, including legal fees, resulting from or

out of Customer's use, or sale for use, of Kyocera modules inarising

applications.

3. Kyocera shall have the right, which Customer hereby acknowledges, to
immediately scrap or destroy tooling for Kyocera modules for which no
Purchase Orders have been received from the Customer in a two-year
period.

Power consumption Pdisp − (150) (225) mW

*1 Maximum contrast is obtained by adjusting the LCD driving voltage (Vop=Vcont) while at the

viewing angle of θ=φ=0°

*2 In consideration of display quality, it is recommended that frame frequency is set in the range

of 70‑80Hz. When you have to use higher frame and clock frequencies, confirm the LCD's performan
‑ce and quality prior to finalizing the frequency values:
Generally, as frame and clock frequencies become higher current consumption will get bigger and
display quality will be degraded.
