Philips 40PFL9704, LED backlight and all the rest

The latest Philips LCD HD Tv is quite a looker. Aluminium brushed case and very good finish, this is what we call a premium tv. It is not cheap at over £1,500 but you pay for the quality here. Like buy a Mercedes or a rover. The connectivity is pretty standard but you get five HDMI ports (one more from the last version).

Image quality is impressive with very deep blacks and vibrant colours. The motion control is also quite something and not seen anywhere else. You almost forget you are watching a LCD tv.

The audio part is not left behind either with one of the best Tv audio system around. Deep bass and clear sound.

It’s not cheap but if you have the money, it’s worth it.

Roundup of the best tablet PC’s

Before you say it, yes tablet PC’s are one of our main interest at the moment and even if not 100% screen tech related they still are sector we feel we should cover a bit more.

Here is a quick roundup of the best PC’s tablet on the market or released very soon:

  • iPad: the Apple most anticipated and a bit disappointing tablet PC. Boast a beautiful 9.7 inches capacitive touchscreen.
  • Freescale: first to release a tablet this year. 7 inch touch screen, and very cheap at around $200
  • HP Slate: screen between 6 and 10-inch. Multi-touch and powered by win 7. later this year
  • Dell Streak: 5-inch of multi-touch display powered by Android
  • Sony Dash: 7-inch screen, internet support, later this year around $199

Multitouch screens on the way to your everyday

Since the apparition of the iPhone we have changed the way we like to interact with things. Nowadays the gadget has to be touch sensitive. it does make sense in the way that touch and gesture are in human nature since the dawn of time where click buttons obviously isn’t.

And now those touch sensitive screem are getting bigger and better. Touch anable desktops pc screen have started to hit the mainstream market and now with the iPad and other slate and tablet pcs it will start pushing for the domination.

I am not too sure how it could touch the TV market so to speak though, but will leave that to the crazy engineers out there.

New Zeon display filter to improve view angles, contrast

A new product from Zeon and targeted at flat panels of all sorts is said improve greatly view angles and contrast compared to standard flat panel we see nowadays.

Those filters should start mass production hopefully around mid 2010 which would make next year the year of the new awesome flat panels.

Improvement in view angles is very welcome and any thing on the contrast ratio side is also beneficial for everyone. Let’s hope it all goes according to plan and that it is not going to add a premium to the already expensive flat panel market.

Sequential or side by side 3D?

3D displays are the next big thing and like in HD, there are different way of displaying a 3D image on a television.

The two ways at the moment are sequential and side by side.

The sequential 3D, used on 3D Blue Ray uses a different frame for each eye. Meaning the transmitter sends 24 images per second per eye, so 48 frames per seconds. The glasses take care of the rest and ensure each eye see only one of the two frame at the same time.

The side by side is a bit different as it sends the two images on the same frame and the TV split and stretch them to form two frames. The quality is not as good as the sequential 3D but the bandwidth used is much much less.

Which TV bracket should I choose?

The best way to support your flat panel screen is by using a TV bracket. Instead of having the screen positioned on a TV unit or a computer table, a better way to view the screen is to fix it securely to the wall.

There are many different types of TV brackets you can choose:

Flat TV Brackets

These brackets mount the screen flat to the wall. They are the cheapest option and offer no movement of the TV after it is fixed into position.

Tilting TV Brackets

These offer a similar solution to the flat TV brackets but also have the added benefit of being able to be tilted by up to 15° downwards. This means the TV can be mounted at a height and angled slightly downwards so viewers can see the screen easily.

Cantilever TV brackets

These are perhaps the most flexible type of TV bracket as they offer the most amount of movement for your TV. You can use these types of bracket if you want to mount your TV in the corner of the room or if you need to move it from left to right to watch the TV from a specific location in the room.

The TV looks stunning and if Sony’s press release plaudits are to be believed, promises to up there with the best TV’s of 2009.

A brief synopsis of plasma

We all love plasma TVs, but behind the screen design, how does a plasma screen work?

It’s thanks to Mr. Noble and the gases he discovered that we are now able to watch this type of TV. The physics is quite simple really; xenon, helium and neon are used in many minute cells situated between two plates of glass. Electrodes are positioned between the glass plates and when an electric charge passes across the electrodes a difference in voltage is created ionising the gas and hence creating a plasma. Light photons are emitted due to ion collisions and excite a small amount of phosphor that coats each cell. Each pixel on the screen is made up of 3 sub-cells which are each coloured with a different phosphor (red, green or blue) and the colours merge to give the overall colour of the pixel.

See, told you it was simple.

SKY TV trial 3D broadcasts

It looks like SKY TV will be the first broadcaster to try to integrate 3D television broadcasts into everyone’s homes. The satellite operator recently trialled their new 3D technology at the ATP tennis finals and the visual results were excellent.

If you own a SKY HD box you will already be able to receive the 3D images (it looks like football will get the first outing) but you will need a 3D TV to view them. Gone and the two tone red and green glasses you had to wear to watch 3D TV in the 70s, but you will still need to wear stylish wrap-around lenses to get the full effect.

The system is scheduled for launch some time around the middle of 2010 so it might not be worth rushing out to buy your new 3D tele yet. But the visuals look stunning and we can’t wait to see what happens over the next few months before launch.

The difference between 1080p and 1080i

At this moment in time the best resolution you can choose is 1080p. But what is the difference between 1080p and 1080i?

The difference between ‘p’ and ‘i’ televisions is the difference in the way the television scans the picture. ‘i’ means interlaced scan, the television scans the picture in two passes each taking about 1/60th of a second. The first pass covers the odd lines and the second pass the even lines. This means a 1080i TV needs1/30th of a second to display the full image. ‘p’ stands for progressive scan, the image here is scanned in one pass. This gives a smoother clearer image and hence is the best option to go for (if you can afford it).
