An image processing system is provided, the image processing system according to an exemplary embodiment of the present disclosure being configured to generate an accurate depth image even in a low light level by obtaining RGB images andor IR images. As the supply voltage drops to less than 2 times of threshold voltage to reduce leakage and save power, generating a relative large swing with a resistor-ladder DAC becomes more difficult. The top ridge member and ridge members are composed of various trusses and connectorcap members that allow the ridge members to pivot or not pivot, in various directions, allowing the frame structure to be folded to its collapsed configuration and unfolded to its expanded position. In some configurations, the voltage to be applied to a sub-pixel may be selected based upon the number of emissive layers in the sub-pixel.
