Samsung’s intelligent mobile display driver IC (DDI)

Samsung Electronics announced today the development of an intelligent mobile display driver IC (DDI), which enables the displays on handheld devices to deliver clearer images in broad daylight. Samsung’s new DDI device automatically measures the brightness of ambient light and determines the optimal image output. While enhancing the visibility of on-screen images outdoors, this DDI device can reduce the power consumption of the display module by nearly 30 percent by lowering the backlight brightness in an indoor environment. The photo-sensor and associated processing scheme in the intelligent mobile DDI divides the detected light into thirty-two levels. The device is designed to select the most appropriate image enhancement algorithm for each of these levels, making the colors more lifelike.

The enhancement algorithm within the DDI analyzes color data of each pixel and reconfigures it to an optimally recognizable condition by adjusting brightness and saturation for crisper visibility. With the primary colors intensified, the LCD images remain bright even when the display is exposed to direct sunlight. Samsung plans to begin mass production of its new intelligent mobile DDI by the end of 2006.
