LCD (Liquid Crystal Display) televisions are thinner and lighter and offer a much sharper and clearer the CRT of similar size. They are ideal for cell phone screens, computer screens, and to view images. LCD TVs have a flat screen there will be no image distortion and no-screen "burn" as the curved tube TVs. In general, the angle of the liquid crystal is 175 degrees. The image can be read 87 degrees on each side. LCD TVs are very economical to use and less than 35 screens are cheap enough. LCD TVs are backlit and block outside light. So they have adapted to situations of natural light. Most LCD TVs have a half life (50% of original brightness) of more than 30,000 hours (16 years of listening to 6 hours per day). LCD, will generally be 13-65, but some manufacturers offer up to 100 dimensions.
Plasma TVs:
A plasma display (PDP) is a flat screen television on the big screen. They have a generation better and more accurate color LCD, and many boards, wider viewing angles and does not undergo degradation at angles higher than the LCD. Plasma displays are ideal for watching videos on the move to the big screen.
plasma screen sizes usually range from 32-84, but some have screen sizes up to 100.
Plasma technology offers a brighter image pixels with more contrast between white and black as standard TV.
Generally plasma TVs, viewing angle is 160 to 180 degrees and the image can be viewed from any angle.
On average, plasma televisions have a lifespan half (50% brightness) of 50,000 to 70,000 hours (20 years of listening to 6 hours per day to 50,000 hours).
Some plasma TVs come with video cards that allows scalable to match the technology of the future.
HDTV:
HDTV or High Definition Television is a system for transmitting digital TV offers higher resolution than ordinary television systems. HDTV is digitally transmitted Unlike analog transmission first, because digital television (DTV) signals require low bandwidth because of digital video compression.
HDTV will be problems with the TV standard, as the sharpness of poor quality, problems with brightness or contrast, stains or other visual defects audio problems such as double images (ghosts), and low signals. HDTV offers clearer images with excellent sound quality, a larger screen and the update scanning. HDTV will provide more channels and higher quality provided by satellite or cable with the standard theatrical experience of the system.
LCD TV:
LED (Light Emitting Diode) TV is an LCD TV that uses LEDs for backlighting instead of fluorescent lamps used (because it creates as many points as blacks). They are ideal for indicators of low energy, as a replacement for traditional light sources for general illumination and automotive lighting.
LCD TV currently costs more than a standard LCD or plasma.
LED TV has obtained very similar and very easy to install.
TV Edge-lit LED consumes energy 30-40% less than LCD or plasma. But the LED backlight consumes more energy.
Growing image can be displayed with LED TV than a standard LCD TV.
TV LED that is illuminated with LED local dimming and RGB will have a better image and better contrast ratio and color accuracy than conventional LCD TVs.
He has a long and environmentally friendly.
OLED TV:
OLED (Organic Light Emitting Diode) TV technology depend on the polymer that emit light. Its characteristics, including,
In OLED TV, there is no need for heating or additional lighting or refrigerators, so there is less power.
How OLED materials has the potential to support the spectrum of visible light, so there will be a higher contrast and refresh rates at high speed.
OLEDs are much faster than LCD. rapid movements and rapid eye movements are more realistic images. OLED TV and virtual images look realistic and can be accessed easily for longer periods.
has wide viewing angle and applying near the eyes, allowing a more enjoyable viewing without distortion.
A disadvantage with OLED TVs is the limited duration of organic materials used in its manufacture. In addition, blue light is rapidly degraded, with a lifespan of 14,000 hours (if used 8 hours a day for five years) on flat screens.
Before you buy a TV, the difference between each technology and buy the one that has the features you want and
your budget.
