DLP Versus LCD Versus Plasma Who Wins?

Texas Instruments Digital TV Is Hard To Beat

Comparing DLP Versus LCD Versus Plasma is a very interesting exercise as they all three are recent technologies in this world which have revolutionised the conventional television and are running a very close competition.

The difference between Digital Light Processing DLP and Liquid Crystal Display LCD is very slight when compared with price, display and performance.

Therefore, if you are going to buy a new flat screen TV this New Year, you have a tough choice.

Looking at the technology we can say that the, Digital Light Processing DLP technology invented by Texas Instruments of America uses the Digital Micromirror Device or DMD chips which consists of over a million minute mirrors.

Each mirror can also be called a pixel. These micro mirrors are activated when they receive the digital signals.

The digital signal transformed in to light get reflected by these micro mirrors which are then sent through red yellow and green filters of a colour wheel which rotates at high speed. Depending on the amount of light reflected by the micro mirrors and processed thorough the three filters of the colour wheel a multitude of shades of colours give rise to vibrant colour images on the screen.

In comparison to the above, a Liquid Crystal Display or LCD screen consists of a number of polarised glass panels. Placed between these glass panels are liquid crystal molecules. 

When light is sent through the liquid crystal molecules these crystals change angles resulting in the projection of a pattern of lightness and darkness that produces images on the screen.

There are three glass panels each of which is of contains pixels of three different colours namely, red, yellow and green.

This technology also produces perfect, vivid images on the screen depending on the angles. The best colours on a Liquid Crystal Display screen could be seen sitting right in front of the screen or placing the LCD screen straight ahead.

If you look at the life span of a DLP TV and an LCD TV it can be said that both have the same. It’s about four years.

Looking at the power consumption, a LCD TV consumes anything between 60 – 300W while a DLP TV consumes anything between 100 – 200W.

If you look at the resolution in pixels, the LCD TV ranges from 640 x 480 to 1280 x 720 to 1920 x 1080. If you look at the number of colours produced by these two, the LCD TV produces 16.7 million and the DLP TV too has almost the same number of colours.

When it comes to brightness there is a slight advantage in the DLP TV. The brightness on LCD TV is 350 – 500 cd/m2 while the DLP TV has a brightness of 400 – 800 cd/m2. The contrast range in an LCD TV ranges from 350:1 to 3000:1 and in the DLP TV it ranges from 1001:1 – 2500:1. 

In conclusion it can be sad that between the Digital Light Processing or DLP TV and a Liquid Crystal Display or LCD TV there is not much of a major difference. What Is DLP Television?
