Custom Monochrome LCD 7 Segment Display Module VA Type High Contrast LCD Display With White LED Backlight
Custom Monochrome LCD 7 Segment Display Module VA type High Contrast Lcd Display With White LED Backlight
Rear polarizer type:
There are three types of polarizer: transmission polarizer; transflective polarizer and reflective polarizer.
A. If No LED backlight, please choose reflective polarizer.
B. If LED backlight is necessary,then you can choose transmission or transflective polarizer.
C. Transflective polarizer is better and expensive than transmission polarizer. But transflective LCD will have a uniform light result compared with transmission polarizer. What is more, when LED backlight is off, transflecitve LCD will also have a good display result.
D. For transmission polarizer, when it is negative LCD or LED backlight alway be on, then it is better use transmission polarizer.

Connection mode of LCD.
How to connect LCD on your PCB?There are four type of connectors for your choice.
1. Metal pin connector. It is very common connection way. Pins should insert into PCB holes and solder it. It is very strong and firm. LCD,LED backlight or PCB can be connected together as a LCD module.
For the connection,If you must make sure that LCD and PCB can be compacted well, or else LCD can't be displayed or just display a part.
But zebra strip is cheap.
3.Heat seal paper.Heat seal paper is a flexible connect way. Heat seal paper can be heated pressing on LCD and PCB directly. But head seal is easy to be oxidized after a few years.
4.FPC(Flexible Printed Circuit) connection. FPC connector is also a flexible connect way. FPC quality is very good compared with heat seal paper. It is a good connection way,but price and tooling charge is higher.
