Note 1: The LED Supply Voltage is defined by the number of LED at
Ta=25℃ and IL =360mA.
Note 2: The “LED life time” is defined as the module brightness decrease to
50% original brightness at Ta=25℃ and IL =360mA. The LED
lifetime could be decreased if operating IL is lager than 360 mA.
The LED lifetime could be increased if operating IL is smaller than
360 mA.

Note 1: Ta is the ambient temperature of samples.
Note 2: Ts is the temperature of panel’s surface.
Note 3: In the standard condition, there shall be no practical problem that
may affect the display function. After the reliability test, the product
only guarantees operation, but don’t guarantee all of the cosmetic
specification.
Note 4: Before cosmetic and function test, the product must have enough
recovery time, at least 2 hours at room temperature.
6. General Precautions
6.1. 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.
6.2. 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.
6.3. 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.
6.4. 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.
6.5. Cleaning
1. Do not wipe the polarizer with dry cloth. It might cause scratch.
2. Only use a soft sloth with IPA to wipe the polarizer, other chemicals
might permanent damage to the polarizer.
