There are pros and cons to each type of projector technology, so when you decide between an LED or LCD projector, make sure you completely understand the big picture. Though they perform the identical function, LED and LCD projectors operate otherwise. Knowing which product will be best for you involves a bit of research and comparison.
About LCD (Liquid Crystal Display) Projectors
LCD technology has been around since 1984 and remains a mainstay in digital projection technology. Unlike traditional film projectors, which shine a beam of light onto individual sheets of film to project an image through a lens aperture, LCD projectors send intense beams of white light through three pixelated displays, breaking it into three distinct hues (red, green, and blue) before blending them in a prism that communicates the beam of light onto a surface. This is accomplished with coated mirrors that allow only certain light waves to pass through when reflecting the light onto an internal crystal screen. Each time an electrical current is triggered, the pixels which make up the display block or allow certain beams of light to pass through the surface. The three display colors then combine in a prism that focuses the single beam and projects it onto a screen.
DLP (digital light processing) projectors vary in price and features. Some are used in movie theaters and are considered’high-end’ technology. This means they are expensive to purchase and maintain. LCD projectors can provide sufficient performance for a fraction of the cost, but they aren’t for all budgets or circumstances. Single-chip projectors cost less than three-chip models, but the three-chip models make less noise and have better color-saturation.
Here are a few more pros and cons to weigh before determining if the technology is ideal for you.
LCD Projector Pros
• Picture Quality: LCD projectors use digital information (USB or DVD) instead of film. Since digital data will not erode with usage, the picture projected on a screen will stay crisp and clear, no matter how often you view it.
• Color Saturation: There is not any spinning colour wheel in LCD projectors – https://alphastech.com/blogs/blog-posts/should-i-buy-led-projector-or-lcd-projector. The hue-combined prism ensures complete saturation of the colour spectrum on display, with no”rainbow” effect common to digital light projectors (DLPs). The lack of a colour wheel also means there’s one less part to wear out or need maintenance.
• Sharpness: The technology in LCD projectors create high contrast, sharp pictures on screen.
• Value: The cost of an LCD projector is anywhere from $200 to $9000–a fraction of the price of high-end DLPs, which can cost upwards of 20,000.
LCD Projector Cons
• Maintenance: You’ll need to clean and keep your LCD projector to make sure it continues to display properly. Dust on the inside screen will distort the projected image, and individual pixels in the prisms may burn out with frequent use, making blank spots in the picture.
• Pixilation: Because of the sharpness of the projected picture, you’re likely to notice the pixilation on the screen display. This effect is known as a”screen door” appearance because the picture looks as though it has been projected through a display.
• Portability: LCD projectors contain several parts, which makes them heavier and less easy to transfer than other types of projectors, such as the handheld Pico projectors, which can be integrated into camera-phones, digital cameras, or computers.
Around Light-emitting Diode (LED) Projectors
The defining factor of LED projectors – https://alphastech.com/blogs/blog-posts/should-i-buy-led-projector-or-lcd-projector is the light source. Instead of a conventional lamp or liquid crystal pixel display, LED projectors to use blue, red, and green reflective diodes to project colored images. LEDs can also be found in some LCD projectors, and they’re often utilised in Pico projectors–handheld projectors that are lightweight and highly portable. They have a very long lifespan, are energy-efficient, and display colours clearly, with little-required maintenance.
LED Projector Pros
• Lifespan: LEDs can last up to 20,000 hours. That is up to 10 times longer than most LCD projectors. This is due to the LEDs with less energy and producing less heat. Since most LED projectors have fewer internal components, they are not as likely to fail.
• Internal Storage: Smaller LED projector components may comprise internal storage.
• Rechargeable Battery: Some handheld LED projectors to come with a rechargeable battery that enables short-term screening”off the grid”
• More Accurate Colors: LED technology reproduces the colour spectrum more clearly on screen.
• Use Less Electricity: LEDs use less power and therefore cost less to operate.
• No warmup/cooldown required: LEDs are energy-efficient and won’t overheat or need time for the mild to t
