The ISL45042EVAL1 and ISL45042EVAL1Z evaluation boards are used to evaluate the ISL45042 LCD module calibrator.
The VCOM voltage of an LCD panel needs to be adjusted to remove flicker. The ISL45042 can be used to digitally adjust a panel’s VCOM voltage by controlling its output sink current. The output of the ISL45042 is connected to an external voltage divider and an external VCOM buffer amplifier. The user can control the VCOM voltage with 7-bit accuracy (128 steps). Once the desired VCOM setting is obtained, the settings can be stored in the non-volatile EEPROM memory, which would then be automatically recalled during every power-up.
The ISL45042EVAL1Z is designed to operate from an AVDD supply (5V to 20V) and VDD supply (2.6V to 3.6V).
