Embodiments of the present disclosure provide techniques and configurations for a display apparatus. In one embodiment, the apparatus may include one or more micro-electro-mechanical system (MEMS) devices. The MEMS device may include a first electrode including a partially reflective surface, a second electrode including a partially or completely reflective surface and disposed substantially parallel to the first electrode, and an analog actuation arrangement coupled to the first electrode, the second electrode or both the first and second electrodes to cause movement of the first electrode from a start position to a selected position of a plurality of end positions, responsive to a selected application of an actuation voltage, to cause the MEMS device to selectively output a reflection of a light in a selected wavelength, or no reflection of the light. Other embodiments may be described and/or claimed.
