Sharp with world’s first four-primary-color 3D LCD

Sharp Corporation has developed the world’s first four-primary-color 3D LCD featuring the industry’s highest brightness with extremely low crosstalk (undesirable double-contour “ghost” images). By wearing special 3D glasses, viewers can enjoy impressive 3D images with an exceptionally realistic sense of depth.


In general, 3D LCDs use a system based on time-sequential display technology with special active LC (liquid crystal) shutter glasses. In this system, images intended for the left and right eye are displayed on the LCD screen sequentially, alternating between the two perspectives. The LC shutters in the special 3D glasses are synchronized with this display, “opening” (becoming transparent) and “closing” (becoming opaque) in such a way that the left and right eye see separate images. The human brain combines these two slightly different images to create the perception of depth in a three-dimensional image. However, displaying 3D images on a conventional display using this system suffered from low brightness and crosstalk.

Sharp worlds first four-primary-color 3D LCD

The newly developed 3D LCD by Sharp offers a radical new solution to the above problems by combining four of Sharp’s unique, one-of-a-kind LCD technologies, including  UV2A technology, Sharp’s core technology for LCD TV panels,  four-primary-color technology, FRED technology, and  side-mount scanning LED backlight technology. This LCD is optimized for 3D TV, as screen brightness when displaying 3D images is 1.8 times higher than that of the conventional displays, and crosstalk is extremely low. Sharp’s four-primary-color technology utilizes four primary colors, adding Y (yellow) to the three conventional primary colors of R (red), G (green), and B (blue). This technology contributes to brighter, more vivid colors thanks to higher light transmission efficiency through the panel and a wider color gamut (range of colors that can be reproduced), which had been difficult to attain on conventional three primary color displays.
