Description

This item was taken from the IEEE Conference ' Brightness improvement of color display systems using white sub-pixel structure and mapping algorithm ' This paper develops methodology and technique for brightness improvement of color display systems using white sub-pixels. Based on human vision discrimination, three novel white sub-pixel filter structures without loss of original resolution are presented to enhance brightness of conventional stripe, delta and pentile color filter architectures. A new mapping algorithm fusing RGB sub-pixel data around a white sub-pixel is proposed to improve overall image quality. Numerous simulation results are provided to show the feasibility and efficacy of the proposed method for improving conventional stripe, delta and pentile display systems. An experimental result is described which has been conducted to show that the proposed color display system performs well for electronic consumer products, such as notebooks, personal digital assistants, and mobile phone, etc.
