DLP vs. LED Projector

The difference between a DLP vs. an LED projector is not as simple as it seems, just like the differences between DLP vs 3LCD projectors. These phrases refer to two separate parts of the projector. The projector may be digital light processing, liquid crystal display, or liquid crystal on silicon (LCoS.) DLP and LCD projectors are the most common, and they use laser light, LEDs, or traditional lamps. However, most of the best projectors use DLP or LCD panels as their projection technology.

Difference Between DLP and LED for Projection

Digital light processing (DLP) projectors use light shined onto a digital micromirror device (DMD,) a chip featuring many microscopic mirrors for individual pixels angled for alignment in each frame. The device shows an alternating image for each of the primary colors (red, green, blue) at speeds quick enough for our brains to merge them. The light from a laser, light-emitting diode (LED) bulb, or metal halide lamp also passes through a spinning color wheel for these images. In some cases, a DLP device backlit by LEDs is referred to as an LED projector. You may also be interested in laser vs. lamp projectors.

Light Source Life for Projectors

LED projectors have a longer lifespan than most other DLP models. Laser models have an even longer lifespan, but they are not as common at home. An LED projector lasts for about 20,000 hours of use, while a traditional lamp model only lasts up to a max of 5,000 hours. After 2,000-5,000 hours, you will need to purchase a projector lamp replacement and replace it. As a result, LED projectors generally have lower maintenance costs and maintenance frequency.

Illuminating Projections

DLP projectors feature higher light output than LED projectors, with at least 2,000 ANSI lumens. LED light projectors have an output of up to 2,000 ANSI lumens of light. However, if you are looking for a projector in a home theater with little ambient light, you will likely not need as bright of a projector. Think about the effect of ambient light like the effect of the sun on a flashlight. If the sun is extremely bright, you can’t distinguish between the two lights. You should consider a laser projector if you need the highest light output.

Color Consistency in DLP and LED Projection

Projectors with a spinning color wheel sometimes suffer from color breaking at close distances. This may not be common among the top long-throw projectors, but this aspect is common in DLP devices since the wheel has to adjust itself many times within a minute to create each color image. However, LED projectors that feature other projection methods without a color wheel do not suffer from color breaking, including LCD technology. In these projectors, the colors are produced using differently colored LED bulbs. By eliminating the color wheel, brands eliminated the color-breaking tendency as well.

Color Accuracy and Black Levels on Projectors

Although they work within the same color space, LED and DLP projectors differ in color accuracy. This aspect partly relies on the fact that LED bulbs come in a wide range of colors, while traditional lamps use white light with a color filter. As a result, LED devices offer enhanced color accuracy and black levels, especially newer models using 4LED. In addition, these devices are designed to create consistency throughout the projector’s lifetime.
