Sharp who is set to launch their new LED and 3D TV range in Australia in the second half of 2010, has developed what they are claiming is the world’s first four-primary-colour 3D LCD TV, which they say delivers a superior viewing experience over models currently on sale from Samsung.
The TV which still requires a viewer to wear special 3D glasses, use a system based on time-sequential display technology with special active LC (liquid crystal) shutters in the glasses.
With the new 3D 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 synchronised 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. Sharp claims that displaying 3D images on a conventional display using this system resulted in low brightness and crosstalk.
Sharp’s four-primary-colour technology utilizes four primary colours, adding Y (yellow) to the three conventional primary colours of R (red), G (green), and B (blue). According to Sharp, the technology contributes to brighter, more vivid colours thanks to higher light transmission efficiency through the panel and a wider colour gamut (range of colours that can be reproduced), which had been difficult to attain on conventional three primary colour displays.
Mark Beard Marketing Manager at Sharp Australia said that the new TV’s which are currently being shown to retailers will be on sale in the second half of the year.
Sharp who is also making Sony’s 3D TV, is one of the leading LCD & LED patent holders.
