FAQ:

1.Why are LCD polarizers required?

Light must be present for the liquid crystal display (LCD) to be readable. It illuminates the display, either by entering the display as ambient light passing through the front of the glass (office light, sun light), or it is supplied from a backlight that is placed behind the LCD. In some cases light is a combination of both ambient light and backlight.

2.How many types of LCD polarizers are available?

These are the three types of LCD polarizers: Reflective, Transflective, and Transmissive. The correct polarizer is determined by the different lighting conditions your product will operate in or be exposed to.

3.What is LCD modules with a Reflective Polarizer:

图片28.png

The reflective LCD polarizer is nothing more than a mirror that is applied to the bottom layer of glass. It reflects 100% of the ambient light entering through the top layer of glass back towards the user.

4.What is LCD Modules with a Transmissive Polarizer:

图片29.png

A Transmissive LCD polarizer, unlike the reflective polarizer, allows all the light from the backlight to pass thought the bottom and top layer of glass towards the user. The backlight must be on for the display to be readable.

Ambient light from office lights or sun light will pass through the bottom layer of glass and not reflect back towards the top glass; so ambient light will add very little illumination to the display.
