2.1 ENVIRONMENTAL ABSOLTE RATINGS
Note (1) The range of temperature and relative humidity are shown in the graph below 95% RH Max. .
(39℃ ≥ Ta) If the temperature is higher than 40 ℃, the maximum temperature of wet–bulb shall be
less than 39℃. No condensation
(2) Vibrate X, Y, and Z axis in the shape of the half sine wave one time for 2ms .
(3) Vibrate the X, Y, and Z randomly within a 5 - 500 Hz range for 30min.
(4) When testing a vibration and a shock, the fixture, which holds the module to be tested shall be
hard and rigid in order for the the module not to be twisted or bent by the fixture.

3. OPTICAL CHARACTERISTICS
The following items are measured under the stable conditions.* The optical characteristics should be measured
in the dark room or the equivalent environment by the methods shown in the Note (5).
Measuring equipment : TOPCON SR-3
Ta = 25 2 C, VLCD_VCC =3.3V, fv= 60Hz, fDCLK = 72.33MHz, IF = 100% duty

Note (1) The definition of viewing angle : The range of viewing angle (10 C/R)
Note (2) The definition of contrast ratio (CR) : The ratio of max. gray and min gray at 5 points
(4, 5, 7, 9, and10)
Note (3) The definition of Response time : Subtotal of the time, during which the transmission changes from
10% to 90% when the TFT turns on and off.
Note (4) The definition of average luminance of white : Measure the luminance of white at 5 points.

Minimum luminance of 13 points
Note (5) Measure the panel, which is left for 30 min. at the normal temp. after leaving it for 30 min with turning
the back light on at the rating. The measurement should be executed under the condition including
the ambient temp., 25℃±2℃, the dark room, windless(removed the direct wind), and no vibration.
Note (6) The definition of white variation at 13 points ( L )
The definition of white variation at 5 points ( L ) : 4,5,7,9.10 point
