Televisions

At this very moment you are looking for information about a television. So what's it gonna be? LCD, LED, Plasma, or DLP display? The choices are wide and often times confusing. If you need help deciding which type and model is right for you, Al's Electronic Center is the right place for you to go.

We have a very large selection of Televisions, so take your time and have a look around at the brands we offer. The only problem you might have is making a choice. After looking around, if you are still uncertain on the model you want, stop in and talk to our professional staff.

Plasma

Plasma displays function differently than any other TV technology in that they actually produce light independently at each pixel on the screen, as opposed to projecting a separate light source through or off of other elements to conjure a picture. A plasma "screen" is actually a dense network of individual cells, three for each pixel of the display (coated with red, green and blue phosphors, respectively). Each cell is impregnated with a rare-gas mixture and connected to an individual electrode. When the electrode for a given cell is charged with an electrical voltage, the gas is converted to a plasma state and emits a burst of ultraviolet light; this in turn causes the phosphors to react and produce bright visible light at the pixel level. By varying the voltage and intensity of the electrical charge, the proper combination of red, green and blue light is produced in each pixel to combine into a bright, colorful composite image. Plasma TVs are available in sizes from about 40" up to 70"+.

LCD

Along with plasma, LCD (liquid crystal display) technology represents a revolution in television design: the truly flat TV. LCD flat-panel displays typically measure around 3" in depth, and are lightweight enough to be mounted on a wall (although they also look mighty sleek on the artsy stands designed to display them on tabletops). LCD is a transmissive technology (as opposed to reflective technologies like DLP). Its light engine streams high-intensity white light (provided by a series of fluorescent tubes woven behind the screen surface) through tiny cells filled with a liquid crystal material. Each pixel has three such cells — one each for red, green and blue components of the signal. When an electrical charge is applied to the liquid crystals their molecular structure shifts modulating the intensity of the light that passes through to the screen. LCD TVs are available IN many sizes, from 10" standard-definition models to widescreen HDTV showpieces of 60.

LED

LEDs can come in two forms, Dynamic RGB LEDs which are positioned behind the panel, or white Edge-LEDs positioned around the rim of the screen which use a special diffusion panel to spread the light evenly behind the screen.

RGB Dynamic LEDs

This method of backlighting allows dimming to occur in locally specific areas of darkness on the screen. This can show truer blacks, whites and PRs at much higher dynamic contrast ratios, at the cost of less detail in small bright objects on a dark background, such as star fields.

Edge-LEDs

This method of backlighting allows for LED-backlit TVs to become extremely thin. The light is diffused across the screen by a special panel which produces a uniform color range across the screen.

DLP

In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a Digital Micromirror Device (DMD). Each mirror represents one or more pixels in the projected image. The number of mirrors corresponds to the resolution of the projected image (often half as many mirrors as the advertised resolution due to wobulation). 800x600, 1024x768, 1280x720, and 1920x1080 (HDTV) matrices are some common DMD sizes. These mirrors can be repositioned rapidly to reflect light either through the lens or on to a heat sink (called a light dump in Barco terminology).
