What is a DLP HDTV and Which is better LCD or DLP?

Q. I recently purchased a blue ray and I want to add a big screen LCD to my home I just started reading about DLP HDTV and I wanted to know if anyone recommends it or have and knowledge or suggestions on what i should get. Thanks for your answers.

A. DLP is a type of video projection. It uses a microchip made of tiny mirrors which can quickly change direction to reflect light towards or away from the lens, which focuses the light on the back of the screen. A color wheel spins in sync with the microchip to add color. This type of system offers the most bang for the buck for large TVs. It offers fairly good contrast (better than LCD but not as good as CRT, LED-backlit LCD, or plasma) and good reliability as well as fast response time, but being a projection TV, viewing angles are relatively limited, the television is too big to be wall-mounted (though not as big as CRT projection TVs from the past), and the halogen bulb must be changed every few thousand hours of use.
I believe Mitsubishi is the only brand still making DLP rear-projection TVs, though DLP front projectors have also become common in both business and home theater setups. If you're looking for a big-screen TV at a relatively reasonable price, DLP is the way to go, as long as it doesn't need to be wall-mounted and if you don't mind changing the bulb.


When is the best time to buy a new tv? Before or after the Superbowl?
Q. Could someone give a brief overview of the differences between LED and HDTV? (I am thinking of purchasing something around 40 inches.)
Also, my purchase would not have to coincide with a Superbowl party. Do you think that prices would be better before or after the game? Or is there a better time of year to purchase a new televsion as new models are introduced?

A. There are 3 type of HDTV which popular in market now LCD HDTV, Plasma HDTV and LED HDTV.

Plasma uses gas plasma cells charged by precise electrical voltages to create a picture.

LCD screens (liquid crystal display) are in layman's terms sandwiches made up of liquid crystal pushed in the space between two glass plates. Images are created by varying the amount of electrical charge applied to the crystals

LED-backlit LCD television or LED TV is an LCD TV that uses LED backlighting rather than fluorescent lights used in traditional LCD televisions

Each technology have their pro & con, here are pro & con for your decision

Pros of Plasma
- Better contrast ratio
- better ability to render deep blacks, more color depth,
- better motion tracking (response time)
- more availability in very large screen sizes.

Cons of Plasma
- more susceptible to burn-in (although this is not as much of a factor now, due to technology improvements in the past few years)
- more heat generation (as well as more power consumption)
- screen glare in brightly lit rooms
- heavier weight, and more delicate to ship.
Good brand that I would recommend for Plasma is Panasonic or Samsung

Pros of LCD
- LCD television advantages include no burn-in susceptibility
- cooler running
- less screen glare, more functional at high altitudes
- longer display life (although improvements are being made in Plasma screen life)
- looks better in brightly lit rooms
- less power consumption than Plasma.
Cons of LCD
- Lower contrast ratio
- not as good rendering deep blacks
- not as good at tracking motion (although this is improving, especially with the implementation of 120Hz refresh rates (and some now offer 240Hz) on higher-end models).
Good brand for LCD that I would recommend is Samsung or Sony

Pros & Cons of LED is almost same as LCD but LED come with better contrast ratio,better picture quality , super slim and 40% less power consumption but higher price

There are good deals before Superbowl party and another good time is around March which there will be new model out and price of old model will drop down.
