Epson Releases New Automatic Luminance Controller IC

TOKYO - Seiko Epson Corp. said on June 28 it had developed the S1F87110, a new automatic luminance controller IC that the company said makes it possible to automatically control backlight luminance in real time. Shipments of samples of this product will commence in July 2007, Epson said, with volume shipments scheduled to begin in October 2007.

The S1F87110 IC is installed with Epson's original luminance control data, making it possible to achieve real-time automatic luminance control according to ambient brightness by simply connecting an external ambient light sensor, according to a press release. This product allows users to utilize the PWM-controlled automatic luminance control function just by hooking it up to their existing LED drivers. Use of this automatic luminance control function reduces LED current consumption by 20-30%, Epson found, while simultaneously improving the picture quality of the display. This product also comes equipped with I2C interface, allowing users to set their own customized luminance control specifications in order to achieve automatic luminance control that is appropriate for any kind of display.
