Seiko Epson has announced the development of the S2D13782F, an image enhancement IC for use in medium- and small-size LCD panels. Adopting the company's original image enhancement technology, the latest IC reduces the level of power consumption in LCD panels.
The IC at the same time corrects input images to optimal brightness, contrast, gamma curve and saturation to achieve good colourful images with fine contrast. The company also facilitates good visibility in subtitles and other text data by applying its adaptive sharpness technology, which automatically distinguishes text and visual domains from input images, and subjects each domain to optimal edge reinforcement processing, according to the company.
The display images and natural light are subjected to automatic analysis by applying its AME2EX - optimiser technology, with controls exercised over the backlighting LED driver using PWM*2 to enable power consumption to be reduced by 30 to 50% from conventional levels, claims the company.
The IC can adjust colour hue, saturation and other parameters using AME2EX colour converter engine technology to eliminate dependence on LCD panel characteristics, says the company. Reductions are achieved in gradation noise occurring due to data omission during data transfer, as well as in the block noise typical of one-segment broadcasting or other digital input images, expressing the picture in smooth and natural fashion, which is known as noise canceller and colour expander technology.
