Abstract

This paper describes a temperature management system for a deformable mirrors of piezo-actuated display package (PADP). This package which is integrated in microbeam projectors is used in portable devices such as cellphones, laptops, and personal digital assistants (PDAs), to name a few. Ambient temperature change is a critical factor affecting the performance of PADP. To reduce this effect of ambient temperature change, a temperature control system using a microheater and a temperature feedback circuit is developed. A computational model of the transient thermal analysis for the feedback control system is also developed. The obtained theoretical results are in a good agreement with the experimental measurements. Under this controlled system, the magnitude of the temperature fluctuation is reduced by ±0.5 °C. In order to enhance the performance of the developed system, various values of the temperature sensor resistance are used, leading to a reduction of about 10% of the temperature fluctuation.
