The reason for the variance is really derived from the type of content displayed. There are a number of different methods to determine what the proper viewing distance should be, some being very technical and others more of a rule of thumb. One of the factors that can help you decide the type of display is the viewing distance as this has an affect on the overall size of the image. LCDs do have a bit of “image retention” with static content, but this tends to go away when the power is cycled.

You should refer to manufacturers on how to set this up on Plasma screens you are installing to avoid the burn in from happening. Plasmas tend to run hotter, and do still have some burn in issues with static content, although this has been improved with advanced design and settings that can add some movement to the screen occasionally. (similar to LCD but each pixel has it’s own RGB grid) LCD uses backlight which shines through a filter to produce a pixel onscreen. Think of Plasma as a miniature LED sign, with the light being produced at each pixel.
Simply put, this lets LCD TV’s produce blacker blacks as the backlight is essentially turned down behind the pixel areas that are black on the image.Īfter saying all this, the traditional difference between LCD and Plasma was the ability to produce true blacks.

With a LED backlight grid, the TV can be dynamically lit or dimmed based on the color of the pixel in a specific area. What manufacturers are referring to with LCD LED monitors/TV’s is that the back lighting is LED. There are other differences concerning lifespan and maintenance between DLP and LCD, but I will leave them for another article.įlat Screen: Competing technologies – Plasma or LCD LEDįirst of all, LED is not really a display technology unless you are talking about an LED digital sign where the pixels are comprised of actual LEDs. If you are trying to color match with LCD desktop monitors, you do not want to use a single chip DLP projector. This is a much more affordable technology, but comes with the disadvantage of having a finite number of colors that it is capable of producing. Single chip DLP uses a color wheel to selectively choose the color of light to pass to each pixel on the chip. This allows a 3 chip projector to produce an infinite number of colors. The 3 chip is much more expensive and creates colors much the same way as LCD with seperate red, green, and blue chips either passing or deflecting away the light. DLP light engines come in two flavors: single chip and 3 chip.

A prism combines the light just before it hits the lens to produce a full color image.ĭLP (a trademark of Texas Instruments) uses a chip of mirrors to pass or deflect light. LCD is based on having light pass through LCD panels acting as red, green, and blue “filters”.
LCD and DLP both have their strengths and weaknesses and you have to understand there are fundamental differences in how the two produce colors on screen. There are two main projector technologies (circa 2011). Projector: Competing Technologies – DLP/LCD
Another benefit is less noise in the room. You will also have quicker power-up times, and typically a brighter better contrast image. One of the advantages of a flat panel over a projector (assuming the screen size is adequate) is the lower maintenance and longer lifespan. The cost per inch of a projector/screen at this point just can’t be matched by a flat panel display. One of the deciding factors that may force one choice over the other is the required screen size (see how to calculate this a bit farther down). You will have a choice to make between a projector/screen combination or a flat panel display. This article will focus on how the visual aspect of the project can be intelligently designed. As an AV Integrator, one of the key elements of every system is visual reinforcement. Although you may be able to get away with picking pieces from a list and throwing them together, sometimes the requirements of the project call for a more in-depth design approach.
