3. Optical Specifications
3.1. LCD Driving Voltage Parameter Recommended LCD Driving Voltage VCC -VEE Symbol Conditions Ta= 0˚C Ta=25˚C Min. – 4.2 Typ. – 4.5 Max. 5.2 4.8 Units V V
Note 1 Ta=50˚C 4.0 – – V Note 1 : 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˚C, 1/16 Duty, 1/5 Bias, VD=4.5V (Note 4), θ= 0˚, φ = –˚ Parameter Contrast Ratio Viewing Angle Response Rise Note 2 TON – Note 1 Symbol CR Conditions θ= 0˚, φ = –˚ Min. – Typ. 4.5 Max. – Units
Shown in 3.3 – 140 210 ms
Time Decay Note 3 TOFF – – 180 270 ms Note 1 : Contrast ratio is definded as follows. CR = L OFF / LON 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 V D VD=VCC -VADJ-VBE Assuming that the typical driving waveforms shown below are applied to the LCD Panel at 1/A Duty - 1/B Bias ( A : Duty Number, B : Bias Number ). Driving voltage VD is definded as follows. VD = (Vth1+Vth2) / 2 Vth1 :The voltage VO-P that should provide 50% of the satulation level in the luminance at the segment which the ON signa.
