GLOSSARY 371 LED TV LED displays are LCD display technology based on light-emitting diodes (LEDs) backlighting the display instead of the cold cathode fluorescent lights (CCFLs) used in standard LCD televisions. LED TVs are also referred to as LED-backlight LCD television. OLED TV OLED TVs use the properties of organic light- emitting diodes. Unlike LED displays OLED displays don't require backlighting, which allows them to use less power than other display technologies. Flat Panel Display Mounts Articulating Arm Articulating mounts have the ability to direct your flat panel TV in virtually any direction making viewing easy from any location. All articulating mounts are considered Universal which means that they will work with most VESA compliant flat panel televisions. Ceiling Mount Flat panel TV ceiling mounts provide the ability to suspend a flat panel TV from the ceiling or any flat horizontal surface. Ceiling mounts are typically used in applications where semi-permanent mounting is desired. All ceiling mounts are considered Universal which means that they will work with most VESA compliant flat panel televisions. Desktop Mount Desktop or Counter top mounts provide the ability to mount a small flat panel TV or display on any flat horizontal surface. Desk top mounts are typically used in applications where semi-permanent mounting is desired. The majority of desk top mounts have swivel and tilting features for greater flexibility of viewing. All desk top mounts are considered Universal which means that they will work with most VESA compliant flat panel televisions. Flat Wall Mount Flat wall mounts provide an easy way to mount a lat panel TV on any flat wall or surface. Flat wall mounts are typically used in applications where semi- permanent wall mounting is desired. Flat panel TV wall mounts keep the screen close to the wall for a very discreet, attractive installation. All flat wall TV mounts are considered Universal which means that they will work with most VESA compliant flat panel televisions. Tilting Wall Mount Tilt wall mounts provide the ability to tilt a flat panel TV upward or downward for a better viewing angle. Tilting mounts are commonly used in applications where the viewing area or seating arrangement falls slightly below the mounted height of the TV. In these cases, tilt wall mounts allow the flat screen to be tilted downward toward the audience for optimum viewing clarity. All tilting mounts are considered Universal which means that they will work with most VESA compliant flat panel TVs. Frame Rate The rate at which frames are displayed. The frame rate for movies on film is 24 frames per second (24 fps). Standard NTSC video has a frame rate of 30 fps (actually 60 fields per second). The frame rate of a progressive-scan video format is twice that of an interlaced-scan format. Free Field Sound waves from a source outdoors where there are no obstructions. Frequency For a function periodic in time, the reciprocal of the period. Unit, hertz (HZ) (ANSI S1.1-1994: frequency). Frequency Analysis An analysis of sound to determine the character of the sound by determining the amount of sounds of various frequencies that make up the overall sound spectrum. i.e. higher frequency sound or pitch vs. low frequency. Frequency Response The range and balance of sound across the audio spectrum. Good sound reproduction requires that all audible frequencies (approx. 20 - 20,000Hz) are reproduced at roughly the same volume, although the highest and lowest octaves are less important. Full Screen/Wide Screen This legend appears on most two-sided DVDs. Full Screen means the image will fill an entire 4:3 (standard) TV monitor, cutting off the sides of the film in order to do so. Widescreen shows the complete picture.
