Cathode Ray Tube (CRT) This is the picture tube based technology that traditional TV sets have used for years. CRTs do not have a fixed (or native) resolution, they are analogue devices. This doesn't mean they can not display digital signals, however any digital signal must be converted to analogue in order for the TV to display the picture. CRTs have been used for decades and are considered to have excellent durability before their picture tubes wear out. Generally a good CRT will require very little if any servicing.
* Many claim that many modern digital technologies lack the black level detail that a good CRT provides. CRTs have a higher contrast ratio that generally results in richer shadow details. * CRT TVs are generally a lot cheaper to purchase than digital sets. * Smaller and lighter than CRT equivalents. * Excellent brightness and picture. Disadvantages: * Really needs low ambient light levels in the room when viewing a DLP TV. Not recommended for viewing in a bright sunny room. Settings can be adjusted for ambient light levels but a dark room is really required to get the best out of these TVs. * DLPs contain a lamp that must be replaced as necessary.
Plasma TVs Plasma TVs consists of hundreds of thousands of individual pixel cells that allow electric pulses to excite rare natural gases (usually xenon and neon), or blue phosphors contained in each cell to display the proper color sequence from the light. Advantages: * Can be viewed in bright surroundings. Disadvantages: * CRTs are a lot bigger and heavier than their digital equivalents. * In order for CRTs to display the proper color sequence from the light. Advantages: * Can be viewed from angles and still retain excellent picture quality. * Thin and light, can be male masturbation hung on a wall.
* Excellent colour, detail and brightness. Disadvantages: * Significantly more expensive than rear projection digital sets. Disadvantages: * Typically more expensive than rear projection digital sets. * There seems to be more variation in the quality across the range of makes and models of plasma sets. The gap between the best sets and some of the cheap ones can be pretty high. * Plasma TVs are less energy efficient than other technologies. * Plasma sets are susceptible to seeing a rainbow like shadowing effect on DLP televisions, especially where there are scenes with highly contrasting dark and light aspects.
Newer DLP TVs with 3 chips have greatly reduced this problem. I own an older one chip DLP and have never experienced this problem. * Poor off-axis viewing. Picture is significantly poorer when watching from an angle, especially vertically. Liquid Crystal on Silicon (LCoS) Similar to LCD, consists of a liquid crystal layer which sits on top of a pixelated, highly reflective substrate. Advantages: * Not susceptible to burn-in issues. Disadvantages: * Typically more expensive than plasma displays of an equivalent size. * Black levels can be quite poor. * LCD TVs are prone to image lag. This is where a rapidly moving object has a tendency to have a ghosting effect due to the pixels not being able to shut off quick enough.
This can be especially problematic when playing video games. Newer models are getting closer to eliminating this effect but they are not there yet. Rear Projection DLP This projection TV technology was developed by Texas Instruments, which is based on their Digital Micromirror Device (DMD) microchip. Each of these chips has hundreds of thousands of individual pixel cells that allow electric pulses to excite rare natural gases (usually xenon and neon), causing them to glow and produce light.
This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the picture. Advantages: * Tried an tested technology..
