Exar Corporation today announced a next generation VCOM control product based on patent-pending innovative architecture. Exar, through its merger with iML, is the leader in flat panel analog products including common voltage (VCOM) management for flat panel display’s picture quality as well as reliability. The iML2911 provides a solution to add two additional power supply voltages readily available in panel electronics. The device employs sensing circuitry for VCOM output load requirement and automatically switches between multiple supply voltage combinations.

This results in 50% savings of energy for still images and 25% to 30% savings for dynamic display images without affecting the quality. The device is also advantageous for use in TV panel applications, where heat dissipation from VCOM buffer devices is a major concern for panel and set makers, as local heating can negatively affect image quality.
