Active Matrix TFT
[top]
A very common type of LCD, used in most laptops, and some LCD panels and projectors. A typical active matrix TFT display is a single LCD (Liquid Crystal Display) that modulates all three primary colors. Most of these offer contrast ratios up to 100 :1 for good color dynamics, and just enough "speed" to handle video and 30 fps multimedia with little or barely distinguishable picture smear or lag.
Aliasing [top]
Jagged edges in text and also along the outer boundaries of diagonal or curved objects. Anti-alaising refers to software compensation that minimize this effect.
ANSI [top]
American National Standards Institute, sets standards for measurements ANSI Lumens, when measured using ANSI methods.
ANSI Lumens [top]
ANSI lumens is a scale to measure the overall brightness value for projectors. The measurement represents the average value of 9 points on the projected screen image.
Aspect Ratio [top]
The ratio of height to width of a frame or screen. The aspect ratio for television is 3:4.
ATA Rated Transport Case [top]
A case rated strong enough to be shipped as freight by common carrier such as FedEx or UPS, etc. Most cases of this type are easily recognized by their aluminum outer shell and metal reinforced corners. Many newer cases are made using lightweight corrugated plastics and weigh much less than the aluminum clad cases.
Audio In [top]
The jack or jacks (typically standard RCA jacks) to plug in sound coming from an external source such as a VCR or computer. Many projectors have more than one set of inputs, making it easy to switch between sources.
Audio Out [top]
The jack or jacks to hook up external amplifier system. Most projectors allow their remote to control the volume of their internal speaker and the external systems.
