WhiteMagic Full HD LCD module adds a dash of white to mobile displays.

One of the perennial problems in mobile technology is how to keep displays bright and crisp, especially under bright sunlight, without putting a drain on the battery considerably. Mobile display manufacturer Japan Display Inc. (JDI) may have one solution with its WhiteMagic TFT LCD module.

Majority, if not all, modern displays are made up of three subpixel colors, commonly called RGB for red, green, and blue. Colors are produced by combining different intensities of these primary colors, with brighter hues containing larger amounts. White is produced by mixing all three in full blast while black, in contrast, involves turning all three off. JDI's WhiteMagic adds a white subpixel of its own. According to the company, this results in a brighter picture without increasing power draw. The module is able to reduce the amount of power used by the backlight, without sacrificing brightness. Outdoors, the display's luminance can reach up to 1.5 times but is able to keep power consumption of the backlight on the same level as regular RGB displays.

The company has already been producing WhiteMagic panels on its Low Temperature Poly-Silicon (LTSP) LCD plants. Previous iterations of the LCD module only supported resolutions such as 640x680 VGA, 540x960 qHD, and 720x1280 HD. With the new LCD module, JDI is able to bump up the specs to 1080x1920 pixels crammed into a 5.0-inch display, giving it a rather high pixel density of 446 ppi. This, of course, makes the panel ideal for smartphones, but JDI is also manufacturing the pieces for other applications as well.

JDI has not released any pricing or availability details for the LCD module, or if it has any big customers on its list. It will be we showcasing the new 5.0-inch Full HD WhiteMagic module Yokohama, Japan next week during the Full Panel Display (FPD) International 2013 convention.
