DLP Projectors

Gone are the days when we used to enjoy watching television screens in black and white. Those days are over. Today, along with the progression of time is the advancement in technology and along with that advancement is our obsession with clearer images and superior sound.

Our entertainment history is broader than most of us would readily expect. One aspect of such the said history is our passion for television. It started as the infamous black and white display, then in the 1950’s colored was introduced, today in the recent years we have endless varieties ranging from LCD, Plasma, to even DLP projectors. If you are not as technologically involved in the latest trends, it would be eminent that this will be the first time you have heard about the latter. Join the club.

To further elaborate, projectors are subdivided into 2 technologies, the Digital Light Processing or commonly known as DLP projectors and the Liquid Crystal Display pertaining to LCD. All of these categorization and difference refers to the internal mechanisms that each of these projectors uses to create and reproduce images. Both DLP and LCD technology have unique advantages over the other, which is why it would be significant to understand what each of this technology has in store for all of us.

DLP Vs. LDC Projector

DLP

DLP projector screens have less chicken wire effect because its pixels are closer together compared to the LCD. Although this does not affect data transfer but it sure produces a smoother and a clearer image. They are more portable because they would require fewer components to work. And finally, it has been proclaimed that DLP projectors last longer than LCD’s.

LCD

LCD is generally more light efficient that the abovementioned. It tends to produce more saturated colors. However, this phenomenon would make people perceive that LCD displays are brighter overall. LCD has the ability to produce sharper images and they do excellent in precise focusing. However, this can sometimes be a disadvantage because it normally makes the pixels more obvious.

Much has already been said about the LCD technology, that’s why this article is focused on the account of the DLP technology.

What Is The DLP Technology?

DLP is the technology that is used in projectors and video projectors. It was invented by Dr. Larry Hornbeck in 1987 at the Texas Instruments. A DLP projector is the only world’s all-digital display solution. It utilizes an optical semiconductor called the Digital Micro mirror Device (DMD) which is a small chip that recreates the source material.

How DLP Technology Works

At the heart and core of each DLP video projector is the powerful microchip that made a glorious change. This so-called ship is probably the most complicated light switch. It includes a rectangular collection of more than 2 million mounted microscopic mirrors. Each of these tiny mirrors measure less than one-fifth of a typical human hair width!
When the DMD chip is synchronized with a graphic signal or as digital video, a light source and a projection mirrors reflect the image onto your screen or to any surface. The DMD chip and the complex electronics that surround it is collectively known as the DLP technology.

Why DLP?

Millions of tiny mirrors creates the clearest manifestation of picture is what makes it amazing. Images and videos produced by DLP projectors are sharper because they have lesser gaps between pixels in one image. They are spaced in less than a micron apart. Other inferior technologies sometimes create a grid of lines commonly referred to as the chicken-wire effect or the screen-door effect.

DLP technology is relatively new in the industry; however it is amazingly pulling off a huge number of interests. This is not to doubt because as they say, images are so clear, it feels like you are there!
