Which one a better LCD PLASMA LED TV?




Ash


And whats the difference?
I ask because I'm buy one for my living room
Thanks in advance



Answer
We had one led tv (samsung) and two lcd tvs (sanyo). We bought a 50" panasonic plasma tv and ended up swiitching all tvs to panasonic plasma (42" and 60"). This product is fantastic. Vivid colors, no blur, no lag on gaming and all are internet connectable (wireless). Supposed glare problem either never occured or on one tv was easily correctable. Burn in problem does not exist anymore, non factor. Viera link is great, gives you other nice options. Plasma has found its time again.

Which is the best buy LCD TV OR LED TV?

I'm looking to purchase a 50inch television, what's better LED or LCD?


Answer
- Top brands: Panasonic (Plasma) and Samsung (LED). (Plasma > LED > LCD). (LCD is going to be discontinued. A LCD tv uses cold cathode fluorescent lamps/CCFL backlights. A LED tv is a LCD tv, but with white or red, green, blue LEDs on the edge of the screen or a full array on the back of the screen).
= Plasma has best picture and audio quality (best response times, best viewing angle, best color quality, less/no motion blur for crisp/clear images because how it's refresh rate works). Newer Plasmas have improved their burn issues by using pixel shifting/scrolling. LCD/LED is best for bright rooms and have most light coming off the screen (Plasmas are not great for bright rooms because of screen glare and faded whites, but do great for dim or dark rooms). Newer Plasmas use less energy consumption and they are cheap to buy. LED are more popular because the manufacturers want to sell you their LED expensive tvs rather than their cheap Plasmas.

- I recommend 1920x1080p for movies, computer monitor/display, some tv shows, and some game console games and I recommend 1280x720p for some tv shows and some game console games. I recommend 40+ inches for movies and/or tv shows and 20-30 inches for computer monitor and 30-40+ inches for game console games.
- FPS (frames per second): Every video consists of a number of frames per second, think of a video as a fast moving flip book. NTSC countries use 60i or 30i FPS (newer stations use 30p or 60p FPS) for tv shows. PAL/SECAM countries use 50i or 25i FPS (newer stations use 25p or 50p FPS) for tv shows. Movies use 24p/25p/30p FPS (first movie to use 48p was LOTR: The Hobbit). Games use anywhere to 2 to 120 FPS (older games use lower FPS while newer games use higher FPS, usually they are up to 60 FPS today).
- TV refresh rate (measured in hz): Example, A tv with a refresh rate of 120 hz means it refreshes/flashes the entire screen 120 times a second.

- How do LED or LCD tv refresh rates work with the FPS of a video? (I recommend real/true 240hz refresh rate, some tv advertising may fool you by listing the fake interpolation or fake backlight scanning/dimming refresh rates).
- http://en.wikipedia.org/wiki/Motion_interpolation (Names of the new technologies for newer tv's at the link): Motion Interpolation or Motion Compensated Frame Interpolation (MCFI), is a form of video processing in which new fake frames are generated between existing ones to up the FPS of a video to reduce motion blur and/or for judder removal/judder adjustment. MCFI video processing may cause gamer input lag and/or artifacts such as the soap opera effect (may ruin the look of a video).
- Many tv's allow viewers to turn motion interpolation (MCFI) off. The tv repeats the frames a certain number of times to match the tv's refresh rate. Example; To display 24 frames per second on a tv with a 120 hz refresh rate, each frame is repeated 5 times every 24th of a second.
- But what happens if the FPS of a video does not match the refresh rate of the tv? Then you get a pulldown, a pulldown is what causes a jittery screen (aka judder) because the tv repeats the odd frames a different amount of times the tv repeats the even frames. Example; A 3:2 pulldown is post popular because it is needed to match a 24 fps video with a 60hz refresh rate tv, odd frames are repeated 3 times (12x3=36) and even frames are repated 2 times (12x2=24) and 36+24=60 FPS for a 60hz refresh rate tv.

How does Plasma tv refresh rates work with the FPS of a video?
- It will take each pixel in a frame and and repeat it a number of times based on the number of sub-field drives (SFD) the tv has with it's refresh rate. Example 1; (NTSC countries) 600hz sub-field drive/motion tv means 60hz FPS x 10 sub-fields per frame = 600hz refresh rate. Example 2; (PAL/SECAM countries) 600hz sub-field drive/motion tv means 50hz FPS x 12 sub-fields per frame = 600hz refresh rate.
- What is focused-field drive (FFD) on Neo-Plasmas? (Light switching speed = better colors and less motion blur) 2500hz focused field drive means sub-fields are virtually packed into 1/2500th of a second as a sharp impluse, creating crisp motion images even in very very fast movining images (FFD is defined as a inverse of light emission period t. 1/t = 1/0.4ms = 2,500 FFD). Regular sub-feild drives like 50 FPS x 12 sub-fields = 600 hz, light emission spreads as wide as 1 field time (1/60th sec) maximum which results in blurry images for very very fast moving images.
- Refresh rates on Plasmas work similar to LED/LCD tv's. These settings are usually automatic, but you can change them in the advanced picture settings, Example 1; 2D 24p FPS mode and choose refresh rates of 48hz/96hz or 30hz/60hz with pulldown (might use interpolation frames for pulldowns), Example 2; 3D mode and choose refresh rates of 96hz for 24 FPS or 100hz for 50 FPS or 120hz for 60 or 24 fps.ect Of course it has gamer mode or many other adjustments.

Does the Samsung LED have more glare than the LCD?

Just purchased the LED because the picture quality looked a bit clearer in the store. However, we placed the tv directly across from a picture window and there is tons of glare. Would I have as much glare with the LCD? Maybe we'll just have to invest in some blinds or move the tv to another part of the room. The picture is perfect at night!


Answer
Samsung uses their "Clear Screen" technology in the A650, A750 A850 and now in the 2009 B650, B6000 & B7000 LCD products. Though these screens pass more light than any other LCD screen on the market, they also have the most reflections and glare of any LCD screen. In fact, these screens produce more reflections and glare than today's Panasonic plasma TVs with their Anti-Reflective filter. Control you light source(s) and this TV will reward your with a fanatistic picture.

Additional Details: Samsung uses the same LCD screen in the new LED series (6000, 7000 & 7100) as they use in the high-end LCD series (650, 750 & 850). Remember that the LED series is still a LCD HDTV, it just used LED back lighting instead of wide color gamut florescent tubes. There is not more glare on the LED series TVs, just the same amount of glare as on the LCD series.

Is there a big difference between matte and glossy screens?




Bacon


The laptop that I want only comes in matte.
My old desktop and college laptops are in matte and the quality is just terrible when compared to my glossy 15" laptop or 40" LED TV.

I can barely look at them, I get eye strain and feel depressed.. which is somewhat strange...

I'm unsure if it's because my desktop is a few years older and the screens on the laptops have bad graphics cards or perhaps they have damage-resistant layers?

Anyway, could you tell me just how different matte is from glossy.
I get 0 reflections on my current glossy screen as my lamp and lights in the house all have shades. In my bedroom the windows face the back of my laptop, hence no glare.

Thank you



Answer
Hi troll,

Glossy screens have vibrant colors and high contrast and brightness because they have a smooth, high-gloss surface. Glossy screens use optical coating to reduce the amount of reflected external light. Their shiny surfaces reflect more light than matte displays. In controlled environments, such as darkened rooms, or rooms where all light sources are diffused, a glossy display may be more enjoyable for the viewer.

Matte screens have anti-glare finish, to scatter the reflected light. Matte screens diffuse light instead of reflecting it so they might be easier to read outdoors, if the backlight provides enough brightness.This characteristic, however, has a number of side effects, which include scattering the light from the display and increasing the blur. Additionally, it results in reduction of the contrast ratio, color intensity, and viewing angle.

Hope the information is useful to you.

Thanks and Regards
