Photoelectric parameters of LCD
The types of LCD: TN(HTN, VA, ETN), STN(FSNT), CSTN, TFT; Type can be seen visually difference, function is different
Various types of optical modes: reflection, semi-reflection, high reflection and high transparency, transmission
Transmittance: The proportion of light passing through
LCD driving conditions: working voltage VOP, DUTY cycle, BIAS ratio bias
LCD working environment: temperature, humidity, UV, anti-glare
LCD resolution: segment, character dot matrix, graphic dot matrix
LCD display quality: contrast, response speed (normal temperature, low temperature, high temperature)
The connection mode of LCD: zebra paper, zebra strip, metal pin, TAB, COG, COF
LCD service life: generally 5 years, the preferred material can be up to 10 years
