Your home theater is made up of several components, but the one that most people will think of first is the picture quality. Whether you have a large screen TV or a projector, you want the best possible image for your home theater experience. What are the pros & cons of LED vs LCD Projectors?
When it comes to choosing between LED or LCD projectors, it helps to know the strengths and weaknesses of each to help you choose the one that is right for you.
LCD stands for Liquid Crystal Display. This technology is familiar to most, as it is found in several products such as mobile devices, TVs, computer monitors, signs, calculators, and watches. As indicated by the name, LCD displays rely on liquid crystals to create images.
LCD projectors operate with a lamp and three LCD panels coloured red, green, and blue. Each liquid crystal can independently turn on or off, either blocking white light from the bulb or allowing it to pass through, gaining colour. The colours are ultimately combined to create an image that is projected onto the screen.
LCD projectors are known for being bright and possessing good color saturation. They produce a brighter image than other types of projectors with the same wattage, perfect for rooms with some ambient lighting. The images are sharp and focused, making the projector great for movies, particularly in larger environments.
LCD projectors tend to be bulky due to the number of internal components. They also collect dust easily, with regular filter replacements and regular maintenance required. The projector can fail with comparative ease and components are expensive when needing to be replaced. The projector lamp will need to be replaced every two years or so.
Finally, LCD projectors also lose image quality over time, and the projector may develop “dead pixels” which are permanently on or permanently off. While this may go mostly unnoticed in the case of a single pixel, if several develop, it will impact your viewing.
While LCD refers to the technology used for image projection, LED refers to the light source, specifically, a Light Emitting Diode. LED projectors, then, are projectors that use red, green, and blue LEDs as their light source, eliminating the need for a halogen bulb.
Because they do not rely on a halogen bulb as a light source, LED projectors run much cooler. They also last longer. A typical halogen bulb may last from 1,000 to 5,000 hours, while the best may last up to 8,000. By comparison, LEDs can last up to 20,000 hours. This represents eight hours per day, seven days per week, over a period of six years and ten months. If it is “only” used four hours per day, five days a week, that becomes more than 27 years. The LEDs will last beyond the lifespan of the projector.
With the combination of red, green, and blue light, LEDs combine to create a white light that is closer to true white light. This gives LED projectors the ability to display more colors than other projectors.
LED projectors are more compact than projectors using traditional lamps, making them easier to place or reposition.
LED projectors have two main disadvantages when compared to LCD projectors. The first is the fact that most LED projectors are not as bright as similar LCD projectors. This may not always be a major consideration. If your projector is intended for use in a dark environment, you may have no issue. On the other hand, if you will be using it in a room where there is ambient light, you may find that the image is not as bright as you would like.
The second disadvantage is the cost. LED projectors can be more expensive, though you may consider this to be offset by the greater light efficiency and lower cost of maintenance and repair.
Both LCD and LED have certain advantages, but overall image quality is what is on the mind of cinephiles. Both LED and LCD can provide beautiful images, so for ease of comparison, we will review and make a direct comparison below:
While neither is a bad choice, there are many personal considerations in the LED VS LCD decision. You may find that the greater brightness of an LCD projector makes it right for you. Alternately, a desire for a greater color range and less need for maintenance may push you toward LED. There is also a DLP projector, which we will talk about in another article. Whichever choice you make, you are sure to enjoy watching movies in your home theater.
