Advantages & Disadvantages

Advantages & Disadvantages

• Advantages

• Slim profile
• Can be wall mounted
• Lighter and less bulky than rear-projection televisions
• Achieves better and more accurate color reproduction than LCDs (68 billion/236 versus 16.7 million/224)
• Produces deep, true blacks allowing for superior contrast ratios (up to 1:2,000,000)
• Far wider viewing angles than those of LCD (up to 178°); images do not suffer from degradation at high angles unlike LCDs
• Virtually no motion blur, thanks in large part to very high refresh rates and a faster response time, contributing to superior performance when displaying content with significant amounts of rapid motion











• Disadvantages

• Earlier models are susceptible to screen burn-in and image retention (however, newer models have green phosphors and built-in technologies to eliminate this, such as pixel shifting)
• Phosphors in older models lose luminosity over time, resulting in gradual decline of absolute image brightness (newer models are less susceptible to this, having life spans exceeding 60,000 hours, far longer than older CRT technology)
• Susceptible to "large area flicker"
• Generally do not come in smaller sizes than 32 inches
• Susceptible to reflection glare in bright rooms
• Heavier than LCD due to the requirement of a glass screen to hold the gases
• Use more electricity, on average, than an LCD TV
• Do not work as well at high altitudes due to pressure differential between the gases inside the screen and the air pressure at altitude. It may cause a buzzing noise. Manufacturers rate their screens to indicate the altitude parameters.
• For those who wish to listen to AM radio, or are Amateur Radio operators (Hams) or Shortwave Listeners (SWL) , the Radio Frequency Interference (RFI) from these devices can be irritating or disabling.
