3.Optical Specif ications
3.1.LCD Driving Voltage Parameter Recommended LCD Driving Voltage Note 1 : VCC-VEE Symbol Conditions Ta= 0℃ Ta=25℃ Min. - 4.2 Typ. - 4.5 Max. 5.2 4.8 Units V V
Note 1 Ta=50℃ 3.7 V - - Voltage (Applied actual waveform to LCD Module) for the best contrast. The range of minimum and maximum shows tolerance of the operating voltage. The specified contrast ratio and response time are not guaranteed over the entire range.
3.2.Optical Characteristics Ta=25℃, 1/16 Duty, 1/5 Bias, VD=4.5V (Note 4), θ=10 ゚, φ=90 ゚ Parameter Contrast Ratio Viewing Angle Response Rise Note 2 TON - Note 1 Symbol CR Conditions θ=20 ゚, φ=90 ゚ Min. - Typ. 7 Max. - Units
Shown in 3.3 - 130 200 ms
Time Decay Note 3 TOFF 130 200 ms - - Note 1 : Contrast ratio is definded as follows. CR = LOFF / LON CR = LON / LOFF LON : Luminance of the ON segments LOFF : Luminance of the OFF segments Note 2 : The time that the luminance level reaches 90% of the saturation level from 0% when ON signal is applied. Note 3 : The time that the luminance level reaches 10% of the saturation level from 100% when OFF signal is applied. Note 4 : Definition of Driving Voltage VD Assuming that the typical driving waveforms shown below are applied to the LCD Panel at 1/A Duty - 1/B B.
