To reach this goals Sony use a newly developed RGBW-method
Sony has succeeded in commercializing “WhiteMagic” an LCD module for digital cameras that utilizes the newly-developed RGBW method.
WhiteMagic incorporates a 3-inch VGA low-temperature polysilicone TFT LCD module that adds a white (‘W’) pixel to the Red-Green-Blue (‘RGB’) pixels. By improving the brightness of the entire screen, Sony has been able to develop a module that offers one mode to reduce the power consumption of backlight by around 50%, as well as another mode that approximately doubles the brightness to improve outdoor visibility. Even adding the W pixel, the analysis of the input picture data and Sony’s unique signal processing algorithm enable images to be displayed without any deterioration.
The ACX432AKM 3-inch VGA low-temperature polysilicone TFT LCD module is available early October, 2011 for about 5,000 yen.
