2 Scope
This specification applies to the TFT LCD module which is designed and
manufactured by LCM Factory of Shenzhen K&D Technology Co.,Ltd.
It is capable of using 262k colors mode 24bit parallel bi-directional interface.
3 Normative Reference
GB/T4619-1996 《 Liquid Crystal Display Test Method》
GB/T2424 《Basic environmental Testing Procedures for Electric and Electronic
Products.》
GB/T2423 《Basic Testing Procedures for Electric and Electronic Products》
IEC61747-1 《SIXTH PARTGB2828`2829-87《National Standard of PRC》
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
(ff=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
(ff=80Hz, Φ=10°θ=270°at 25℃)
③ Vop: (Vth1(50%)+Vth2(50%))/2 (ff=80Hz, Φ=10°θ=270°at 25℃)
4.2 Definition of Response Time Tr, Td
①Tr: The time required which the brightness of segment
becomes 10% from 100% when waveform is switched to
selected one from non-selected one. (ff=80Hz,
Φ=10°θ=270°at 25℃)
