Note 1: Definition of viewing angle range
Fig. 4-1 Definition of viewing angle
Note 2: Definition of optical measurement system.
The optical characteristics should be measured in dark room. After 30 minutes
operation, the optical properties are measured at the center point of the LCD
screen. (Response time is measured by Photo detector TOPCON BM-7, other
items are measured by BM-5A/Field of view: 1° /Height: 500mm.)

Note 3: Definition of Response time
The response time is defined as the LCD optical switching time interval
between “White” state and “Black” state. Rise time (TON) is the time between
photo detector output intensity changed from 90% to 10%. And fall time (TOFF) is
the time between photo detector output intensity changed from 10% to 90%.

6. General Precautions
7.1. Safety
Liquid crystal is poisonous. Do not put it in your mouth. If liquid crystal touches
your skin or clothes, wash it off immediately by using soap and water.
7.2. Handling
1. The LCD panel is plate glass. Do not subject the panel to mechanical shock or to
excessive force on its surface.
2. The polarizer attached to the display is easily damaged. Please handle it
carefully to avoid scratch or other damages.
3. To avoid contamination on the display surface, do not touch the module surface
with bare hands.
4. Keep a space so that the LCD panels do not touch other components.
5. Put cover board such as acrylic board on the surface of LCD panel to protect
panel from damages.
6. Transparent electrodes may be disconnected if you use the LCD panel under
environmental conditions where the condensation of dew occurs.
7. Do not leave module in direct sunlight to avoid malfunction of the ICs.
7.3. Static Electricity
1. Be sure to ground module before turning on power or operating module.
2. Do not apply voltage which exceeds the absolute maximum rating value.
7.4. Storage
1. Store the module in a dark room where must keep at 25±10℃ and 65%RH or
less.
2. Do not store the module in surroundings containing organic solvent or corrosive
gas.
3. Store the module in an anti-electrostatic container or bag.
