The new LCD module has a high resolution of 329 ppi (pixel per inch) around the limits of the human eye. In addition to this capability, the new LCD module comes with the newly developed technology for high aperture ratio pixels as well as improved backlight efficiency in LCD displays in preventing reduced brightness that occurs during design of high-definition displays with superior color reproduction.
The new module has a aspect ration of 16:9, display area of 55.51mmx98.69mm, brightness of 500cd/m2 and contrast ratio of 1100:1.
