Technical Examples

A drive control circuit for controlling an electrochromic element is substantially integrated into an integrated circuit, with the exception of resistive elements for dissipating heat away from the integrated circuit. The drive control circuit includes a current regulator for generating a select one of at least two discrete amounts of current to drive the electrochromic element. Further, a control system individually controls a plurality of electrochromic elements and includes shunts coupled in parallel with the individual electrochromic elements. The control system controls the ratio of the reflectance of the individual electrochromic elements as a function of sensed glare.
