*The total power dissipated by the HVDD supply may be approximated using the equation
Total HVDD Power = (CLOAD × HVDD × Pixel Frequency) × HVDD × Number of H-Outputs Used
Actual HVDD power may be slightly higher than the calculated value because of stray capacitance inherent in the PCB layout/routing.
Specifications subject to change without notice.
(RGVDD = HVDD = 2.7 V to 3.6 V, DVDD = DRVDD = 2.7 V to 3.6 V, CL = 20 pF, TMIN to TMAX, unless
