The next generation of tablets could have ultra-sharp "retina" displays if Samsung has anything to say about it. The Korean electronics giant plans to demonstrate an high-resolution LCD screen with a pixel density of 300 dpi and with a 40 percent power savings over current models.
The screen is based on a display technology called PenTile, which adds a fourth "color" to the traditional trio of colors in LCD screens, red, green, and blue (not to be confused with Sharp's QuadPixel tech, which adds yellow). The fourth color is white, which makes the panel much more efficient. Typical LCDs use a combination of the colored pixels to produce white light, but the PenTile panel primarily uses the white pixels for this. Since a large chunk of image content is white or light colors, less energy is needed overall.
