Preview of Philips's World First 21:9 Cinema Format LCD TV

Philips Cinema 21:9 9000 Series BDP9100 TV , launched in Hong Kong.
An Eisa award best Product 2009-2010,
World First Cinema Screen aspect Ratio 21:9.

Not like the traditional 16:9 that has to chop of the left and right portion of the picture,
This 21:9 matches perfectly with the Blue Ray format, full display to fill up the whole screen
Plus other stunning feature as the Ambilight Spectra 3 technology, an extension of the picture by the illumination from the back side of the LCD TV onto the wall.
This improve he vibrant of the picture display, reduce eye tiredness, enlarged screen effect.

This technology was developed by Light Research Centre Rensselaer Polytechnic Institute in 2005.

World fasters LCD response 1ms, Made in USA, 200Hz frame rate, Perfect Pixel HD Engineer 09 CPU that manipulate 500M pixels in 1 second, 17 bit video processor that can create 2250 Trillion colors.

Size 56” Price is about HKD$50,000. One shortcoming is the LCD Back light built by CCFL, not LED!. I think the next advance model will be LED White direct back Light format!

Top 5 LCD Monitor makers

While Samsung Electronics and LG Electronics increased their market share with aggressive marketing strategy in not only LCD Monitor but also TV in August, other Brands showed lowered production output in August compared to July due to stock level adjusting.

In terms of shipment market share by maker in August, Samsung Electronics comprised 18% market share by producing 2.4M units to be ranked in No.1 and Dell was ranked No.2 with 15% market share that had decreased 7% from July and LG Electronics was ranked in No.3 by adding 10% market share M/M to 13%.

With high activities in China market, Lenovo's shipment market share increased 14% M/M to 5.6% in August to be ranked in No.6 position.

Last year shipment ranking is Samsung as No.1 with market share 17.4%, followed by Dell 14.2%, HP 12.0%, Acer 11.7%, LG 11.5%, Lenovo 6.8%...

In Short, Samsung is LCD TV, Monitor, Netbook market leader and being 2nd as for Handphone. I see not reason why Samsung could be the handphone No. 1 market share leader in another 2 years!

Samsung's Field Emission Technology on LCD TV

Samsung’s field emission backlight (FEB) demonstrated LCD TV was able to improve the contrast ratio to 300,000:1.

The FEB has an array of pixels that can be turned on or off depending on the image that is being shown. The FEB implementation in Samsung’s demonstration is divided into 2,800 squares (70 x 40) that are 1cm (~0.39″) on each side and allows for precise control of luminance. This type of backlight control technology is called local dimming and has been enabled first by use of LED backlights. But even the best prototype implementation of LED backlight based local dimming is limited to less than 2,000 areas.

For instance, Dolby’s High Dynamic Range technology was implemented by SIM2 on a prototype LCD TV with 1,838 LEDs with individual control over them. This SIM2 LCD TV prototype was considered one of the best showcases of contrast ratio based on local dimming. The SIM2 LCD TV prototype was able to improve contrast up to a minimum of 25x the LCD’s native contrast ratio. If for example a LCD TV panel has 1,000:1 contrast ratio, by implementing Dolby’s HDR technology to the fullest, you can expect a contrast of 25,000:1. This is still considerably less than Samsung’s FEB-based 300,000:1 contrast ratio.

Field emission technology is a variation on how CRTs and plasmas work by using electrons to excite phosphors on a screen. In Samsung’s example the control is fine tuned by the use of carbon nanotubes and a unique structure. The carbon nanotubes are used as emissive tips. Nanotubes are deposited on a flat surface and is applied with an elastomer. The elastomer allows the exposed nanotubes to stand up, which then can be used as emissive tips. A TFT-like grid is layered above the nanotubes to control the movement of electrons to excite the red, green and blue phosphors. The FEB generates brightness of 6,000 cd/m2. The layers in the LCD, especially the color filter, absorbs about 95% of that brightness and allowing just 300 cd/m2 to be seen by the viewer.
