The VCOMvoltage of an LCD panel needs to be adjusted to remove flicker. The ISL45042 can be used to digitally adjust a panel's VCOMvoltage by controlling its output sink current. The output of the ISL45042 is connected to an external voltage divider and an external VCOMbuffer amplifier. In this application, the user can control the VCOMvoltage with 7-bit accuracy (128 steps). Once the desired VCOMsetting is obtained, the settings can be stored in the non-volatile EEPROM memory, which would then be automatically recalled during every power-up. The VCOMadjustment and non-volatile memory programming is through a single interface pin (CTL). Once the desired programmed value is obtained, the Counter Enable pin (CE) can be used to prevent further adjustment or programming. The full-scale sink current of the ISL45042 is set using an external resistor connected to the SET pin. The full-scale sink current determines the lowest voltage of the external voltage divider. The ISL45042 is available in an 8 Ld 3mm x 3mm TDFN package with a maximum thickness of 0.8mm for ultra-thin LCD panel design.
