We find that the most popular backlighting for small LCD modules is LED.
The definition of small LCD display is a character display ranging from an 8×1 LCD display up to a 40×4 LCD module.
The popularity of LED side lit or LED back lit (Array lit LED) is due to the following advantages.
- No noise that is found with AC applications such as EL backlight or CCFL backlight.
- Longer life
- Variable brightness
- Does not require an AC inverter.
To increase the brightness of the LED backlight, change the value of the current limiting resistor. NOTE: The brighter the LED backlight, the shorter the lifetime of the backlight.
