According to PCMag, Samsung announced, all its future tablets will be equipped with a high-resolution LCD screen, with a pixel density of 300 dpi and with a 40% 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.”
