FAQ:

1. How many LED colors are available for LCD character module

The LED is available in several different backlight colors including blue, green, white, yellow-green, amber, red, white, and RGB.

2. What is Alphanumeric / Character LCD ?

A character LCD can show a fixed set of numbers and letters in a simple 5×8 dot monospaced font.

The font is stored in the LCD’s controller (the CGROM), so when you want to display an “A”, you simply send over the ASCII code for “A.”

Alphanumeric / character LCDs are typically a nice combination of low cost, good function, and ease of application.

3. 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.

4. What are the types of LCD polarizers?

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.
