Improved LCDs for Digicams/Smartphones

Who would have thought the addition of the color white would brighten the LCD screen world? Well, apparently it has as Sony recently announced that by adding a white subpixel to the LCD process they have dramatically improved both the power consumption and outdoor visibility of a 3-inch VGA LCD module and are squarely aiming the technology at the digital camera and smartphone markets.

As you may or may not know, standard LCDs have red, green, and blue subpixels. Despite the fact that the addition of a white pixel can cause image quality deterioration, Sony is claiming that its analysis of the input picture data and new signal processing algorithm overcome these issues.

The module Sony has demonstrated actually has two modes, one that reduces backlight power consumption by around 50 percent and a second that approximately doubles the brightness to greatly improve outdoor visibility. The display also has a 160-degree viewing angle. All three of these issues have plagued LCD viewing for years.
