Looking for a new television can be a confusing experience. With all of the latest TV technologies, it can be difficult choosing the best TV for you. Two types of televisions that people will often compare are the LCD TV and LED TV. haier tv The following is a brief guide on the difference between an LCD and LED television to help you make your television selection.
Technically speaking, LCD TVs and LED TVs are both LCD TVs. The screen on both types of TVs is a liquid crystal display. The LCD television is a flat-panel television. With a LCD display, there are 2 layers of polarized glass which are joined together. The liquid crystals are contained in one of the layers. The liquid crystals pass or block the light to display the television image. The crystals do not produce their own light. The light comes from fluorescent lamps that are located at the back of the screen. Arranged in a grid are millions of shutters that open and close to release light and capture light that is not needed to produce images. Each shutter is paired with a colored filter which produces a sub-pixel. The sub-pixels are so tiny that when they unite they produce a single pixel. It displays as a single speck of color on the screen. Along with the assistance of fluorescent lamps, the television images that we view are created. LCD television can be quite thin and create high quality images. These TVs take up less space and they can even be hung.
LED TV’s also have a flat-screen and use Liquid Crystal Display technology. However their source of light is different. LED TV uses Light Emitting Diodes LED. There are two types of LED back-lighting – Edge lighting and Full-Array lighting. The Edge lighting utilizes a series of diodes are that are arranged along the exterior edges of the screen. The light is dispersed across the screen. Full-Array lighting involves a number of rows of diodes behind the entire surface of the screen allowing for more control over dimming and brightness as the diodes can be switched on and off.
If you are not familiar with the current TV technologies, it can be difficult understanding the choice between LCD and LED televisions. Although LED TV’s and LCD TV’s both use Liquid Crystal Display technology, the key difference is that the LED TV uses Light Emitting Diodes while the standard LCD TV uses fluorescent lamps. When it comes to LCD TVs, Edge-lit television sets are normally lighter and thinner than a Full Array because the lighting source takes up less space. Full-array television sets are thicker and heavier, but one section of the LED panel can be dimmed while other sections stay bright which improves blacks and contrast in the television image. Edge lighting television sets are the lightest and thinnest TVs on the market.
LED TVs are more expensive than LCD televisions. Each type of television has its own advantages and disadvantages. The choice will depend on your needs and television preference.
