The inverter converts DC to AC at a high frequency, which is useful in powering electroluminescent lamps such as EL and CCFL backlight.
Many graphics LCD module manufactures are discontinuing the production of displays that contact a CCFL backlight. Please see our blog relating to CCFL backlights.
If the LCD Displays module contains an EL backlight there has to be AC power. If the customer can only supply DC (direct current), then there has to be an inverter that converts from DC to AC.
Focus Displays does not provide an onboard inverter on any of our alphanumeric LCD Displays.
It is not common for most monochrome LCD manufactures to supply the inverter on any of the following Numeric LCD Displays.
