GB/T4619-1996 《Liquid Crystal Display Test Method》

GB/T2424 《Basic environmental Testing Procedures for Electric and Electronic Products.》

4 Definitions

4.1 Definitions of Vop

The definitions of threshold voltage Vth1, Vth2 the following typical waveforms are applied on liquid crystal by the method of equalized voltage for each duty and bias.

【 selected waveform 】【 non-selected waveform 】

① Vth1: The voltage which the brightness of segment indicates 50% of saturated value on the conditions of selected waveform

(f f=80Hz, Φ=10°θ=270°at 25℃)

② Vth2: The voltage which the brightness of segment indicates 50% of saturated value on the conditions of non-selected waveform

(f f=80Hz, Φ=10°θ=270°at 25℃)

③ Vop: (Vth1(50%)+Vth2(50%))/2 (f f=80Hz, Φ=10°θ=270°at 25℃)

4.2 Definition of Response Time Tr, Td

Tr: The time required which the brightness of segment

becomes 10% from 100% when waveform is switched to

selected one from non-selected one. (f f=80Hz,

Φ=10°θ=270°at 25)

Td: The time required which the brightness of segment

becomes 90% from 10% when waveform is switched to

selected one from selected one. (f f=80Hz, Φ=10°θ=270°at

25)

4.3 Definition of Contrast Ratio Cr

Cr=A/B

① A: Segments brightness in case of non-selected waveform

② B: Segments brightness in case of selected waveform

4.4 Definition of Angle and Viewing Range

Angular Graph: Constrast Ratio

Such as:

Viewing Angle Range:

80(Cr>2) Horizontal

70(Cr>2) Vertical
