The advantages and disadvantages of DLP projectors

Digital Light Processing (DLP) is a show device based mostly on optical micro-electro-mechanical digital micromirror device. DLP is used for a wide range of show applications from traditional static displays to interactive displays, as well as non-traditional embedded functions together with medical, safety and industrial applications.

Compared with competing technologies, DLP gives sharp, colorful, clear distinction images. Since the house between each micromirror is less than 1 micron, the house between pixels is drastically limited. Therefore, the final image appears clearer. With the use of a mirror, the light loss is vastly reduced and the light output is kind of high.

Smooth (1080p resolution), no jitter image. Excellent geometry and glorious grayscale linearity are achievable

Utilizing a changeable light source signifies that it may take longer than CRT and plasma shows, and the light from the projected image just isn’t inherently polarized. Light sources are easier to replace than backlights for LCDs and lighter than LCDs and plasma TVs, which are often person replaceable. The new LED and laser DLP show system more or less eliminates the need for lamp replacement. DLP offers affordable 3D projection shows from a single unit and can be used with both energetic and passive 3D solutions.

Unlike liquid crystal displays and plasma displays, DLP shows do not rely on the fluid as a projection medium and subsequently are not limited by their inherent mirror mechanism, making them supreme for growing HD cinema and venue screens.

The DLP projector can handle up to seven totally different colours, giving it a wider shade gamut.

DLP, which represents digital light processing, is a Texas Instruments technology. It uses mirrors and colour wheels to mirror and filter the projected light. For home and enterprise use, the DLP projector uses a reflective panel for all three colors. Digital cinema has three-panel DLP projectors priced at more than top 10 mini projector,000 US dollars. Most individuals only learn about single-panel DLP projectors.


The only downside of DLP projectors is what believers call “rainbow effects.” Client DLP projectors use clear shade discs (half-color wheels) rotating in entrance of the lamp. This disk, divided into a number of major colours, reconstructs all the final colors. The position of these main colours is like the slice of pie. Relying on the projector, there may be 3 segments (1 red, 1 green and 1 blue) or four segments (1 red, 1 green, 1 blue and 1 white), 6 segments (1 red, 1 green, 1 blue, then 1 red, 1 green and 1 blue), and even 8 segments have just a few white. The smaller the section, the less the turntable, the stronger the flexibility of the eyes to disassemble the color. This means you sometimes see something like a rainbow, especially in bright areas of the image. Thankfully, not everybody sees these rainbows. So before buying a DLP projector, be sure to check out some video sequences.

Some viewers discover the tweeter of the color wheel an annoyance. However, the driveline may be designed to be silent, and some projectors do not produce any audible colour wheel noise.

The edges of the projected image between black and light are often jagged. This is called jitter. This is how the image transitions from one coloration to another, or how the curve appears in the image. In DLP projectors, the way to current this gray transition is by turning the light supply on and off quicker in this area. Often, inconsistent dither artifacts can happen in color conversions.

Because one pixel cannot render shadows exactly, error diffusion artifacts caused by averaging shadows on completely different pixels
