Note (1) Please follow the power on/off sequence described above. Otherwise, the LCD module might be
damaged.
Note (2) Please avoid floating state of interface signal at invalid period. When the interface signal is invalid,
be sure to pull down the power supply of LCD Vcc to 0 V.
Note (3) The Backlight inverter power must be turned on after the power supply for the logic and the
interface signal is valid. The Backlight inverter power must be turned off before the power supply
for the logic and the interface signal is invalid.
Note (4) Sometimes some slight noise shows when LCD is turned off (even backlight is already off). To
avoid this phenomenon, we suggest that the Vcc falling time is better to follow 5msЉt7Љ300 ms.

Note (0) Light source is the standard light source “C” which is defined by CIE and driving voltages are
based on suitable gamma voltages. The calculating method is as followingΚ
1. Measure Module’s and BLU’s spectrums. White is without signal input and R, G, B are with signal
input. BLU is supplied by CMO.
2. Calculate cell’s spectrum.
3. Calculate cell’s chromaticity by using the spectrum of standard light source “C”
Note (1) Light source is the BLU which is supplied by CMO and driving voltages are based on suitable
gamma voltages. White is without signal input and R, G, B are with signal input. SPEC is judged
by CMO’s golden sample.
