The
Quattron is a world first, coming with a unique 4 colour technology. What SHARP has done is it added a fourth yellow sub pixel to the colour matrix of RGB. Now this TV can now produce more shades of colour, giving 1000 times more than any other television.
Sharp invented the
LCD TV 22 years ago. Now it has reinvented the technology.
This new Sharp LCD TV is an ingenious innovation called the Quattron. The Sharp LC-46LE821E LCD TV uses a unique 4 colour technology. Although the 3D hype is on, this is a bold new step to introduce this television. The
Quad Pixel technology uses an innovation of adding a yellow sub-pixel to the standard RGB colour matrix. So it can produce shades of colours never seen before. Sharp has expanded this fundamental aspect of colour TV construction really significantly. The pictures here look much brighter and be able to reproduce a wider portion of the video colour spectrum.
The challenge faced by Sharp was to add a fourth sub-pixel and to reduce the size of each sub-pixel in the LCD picture by a full quarter, but full HD resolutions are retained in all the screen sizes. The flat panel Screen resolution is 1920 x 1080 and with refresh rate of 100Hz on 16:9 aspect ratio. The televisions come in 40 inches and 46 inches versions in the lower range, named the 40LE821E and 46LE821E respectively, but lacks the DNLA, the time shift and the flat front factors.
Meanwhile the top end E921 models will only come in September with 200Hz and in larger sizes of the 60-inch (60LE921E), 46-inch (46LE921E) and 40-inch (40LE921E)versions.
Connectivity highlights include four HDMIs, a USB port able to play JPEGs or DivX HD files. It has an RS-232 control jack, has the in-built Freeview HD tuner and an Ethernet port. All connections are entered from the side, rather making it easier to wall mount. Its colour response is really good. It reproduces sound quite reasonably well. The Quad Pixel technology takes a welcome step forward for LCD technology, yet there is still room for improvement in other areas.
