2 Scope
This specification applies to the STN LCD module which is designed and manufactured by Lanser Displaytech Inc. It is capable of using 8bits data bus and operating with 8080-series or 6800-series MPU.
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
Vth1: The voltage which the brightness of segment indicates 50% of saturated value on the conditions of selected waveform (ff=80Hz, =10 =270 at 25 ) Vth2: The voltage which the brightness of segment indicates 50% of saturated value on the conditions of non-selected waveform (ff=80Hz, =10 =270 at 25 ) Vop: (Vth1(50%)+Vth2(50%))/2 (ff=80Hz, =10 =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. (ff=80Hz, =10 =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. (ff=80Hz, =10 =270 at 25 )
