Abstract

In order to improve the approach of the conventional LCD colored image display that has been using color filter, this research is to lead a unique innovative design by using three colors bank scrolling backlight. The backlight scrolling uses Light-Emitting-Diodes (LEDs) to replace the conventional cold cathode fluorescent lamp for fleetly light alternating between Red, Green, and Blue. Images with bank segments can be displayed in terms of RGB colors in time series. According to the human persistence of vision effect, a colorful image can be demonstrated. The advantages of this three color bank scrolling can provide a cost saving because there is no color-filter of the display, resolution tripling with RGB on the same pixel, and abundant in color saturation for the selection of dedicating wavelength LEDs color mixture. Practically, this research contents the experiments of three color bank scrolling, a building up of the prototype for backlight system, optics adjustment for a proper color mixture. The results of this research show the system not only could displace the color filter but also triple the resolution. Consequently, the system is practicable and can be proposed as a new innovation to LCD industry.
