What is the purpose of the LED projector?

LED projectors have been gaining a lot of buzz lately because of how swiftly the technology works. Instead of using the traditional halogen lamp as the light source like most of the old projectors, they use LED (light-emitting diodes) in order to project video content on a flat-screen. This is quickly becoming a trend in the market. Not only is it more efficient, but it is actually revolutionized the technological world. This working principle is further combined with the portability of a mini projector. Thus, the end product is a flexible, portable, and highly functional LED projector that can gradually make human life better and easier.

Types of LED projectors

1. Standalone LED projectors: Standalone LED projectors are the devices that need a cable to connect its body to an external device for projecting content. Usually, USB and HDMI cables are used for serving these requirements. The external devices send video signals to the project that in return projects content on the screen. These Standalone LED projectors have inbuilt rechargeable batteries that provide it with enough power to stay awake during the operating.

2. Embedded LED Projectors: Embedded LED Projectors contain the ability to embed their body in an electronic device. The required video signals and needed power for its operating is derived from the connected electronic device.

3. Media Player: Media Players are the devices that don’t require any external device for acquiring video signals. These devices are pre-placed memory card slots. Users just need to insert an external memory card in these slots. After the insertion, these media players derive video signal input from the memory card and projects content on the screen. Like Embedded LED Projectors, Media Players also don’t require cables for their operation.

4. USB LED Projectors: USB LED Projectors are the devices that need users to connect an external device to their body using a USB cable. These devices are often referred to as USB Projectors. The USB cable initially fetches the required input video signals and the power to operate from external systems. The derived signal and power are used for projecting video content on the screen. These devices are comparatively smaller as they do not contain an inbuilt battery. The power is directly derived from the external system.

Technologies Used in LED Projectors

LED projectors explicitly use any of these three technologies for its working:

• Digital Light Processing (DLP): DLP technology was initially developed by Texas Instruments，it can be used in DLP smart mini projector

  DLP technology was initially developed by Texas Instruments，it can be used in. The technology uses a standard white light source and numerous other filtering techniques for projecting content. The white light source is directed towards tiny mirrors. These small mirrors are placed on chips. They direct this light on the screen and ultimately, video content is projected on it. These mirrors work in two-state, namely ON and OFF state. When the system is ON, the brightness of each pixel increases whereas it decreases when the system is OFF. These mirrors also control the color of each pixel. Precisely, a color wheel is fixed between the white light source and tiny mirrors. The color wheel acts as a medium with which small mirrors control the color of pixels. The wheel splits into primary colors. These colors mix and the needed color is projected on the designated pixel.

• Liquid Crystal on Silicon (LCoS): LCoS technology also uses a white light source to project content like DLP technology. In this case, small LCDs are utilized for projecting video content. They control how much light is cast on each pixel. Two basic designs are used in LCoS technology. These two technologies can be listed as Color Filter (CF- LCoS) is a technology that uses three subpixels to project video content. These pixels have primary colors that cast color on pixels. Field Sequential Color (FSC- LCoS) on the other hand split the input image into three main divisions of the existing three primary colors: Red, Green, and Yellow. Nowadays faster LCDs are used for refreshing these main divisions regularly without any break.

• Laser Beam Steering (LBS): LBS technology was brought into light by Microvision. Unlike the previous two technologies, this technology uses lasers for its operation instead of a white light source. Optical principles are used to coalesce 3 different primary colored laser beams. Ultimately images are formed on the screen because of these laser beams. These images are scanned at a quick rate to avoid any kind of scanline effect. The only disadvantage of LBS technology is that it is more harmful to human eyes compared to DLP and LCoS technologies. However, LBS technology projectors are smaller in size and also consume less power comparatively.

An LED projector is a device used to display videos or presentations in an enlarged format. "LED" stands for "light emitting diodes." That's important because these diodes are the lighting source for the projector. An LED projector is a 21st century replacement for the slide projector and the overhead projector, so common in the mid to late 20th century.

Shopping for an LED Projector

Although shopping for an LED projector was once difficult, simply because they were so scarce, today that's different. They're readily available in several varieties, with different specs and in different price ranges. As with most specialty electronics, though, you'll usually do better to shop online, as it's easier to find one in the right configuration and the right price.

Selecting the right LED projector is easy if you first decide what you need to use it for. The two main factors that will dictate which one you buy are the projector's cost and specifications. Knowing how you'll use your projector will help you decide how much you should spend for it and what features you need. Let's look first at some of the specifications that vary from one projector to another.

Technical Specs

Some of the specs that you need to consider include:

• Aspect Ratio. This refers to the width of the screen vs. its height. Screens with SVGA, VGA, XGA and UXGA resolution all have an aspect ratio of 4:3. Because this is the standard, there's not much choice here.
• Brightness. You'll find this measured in something called "lumens." The higher the number of lumens, the brighter it should be. Naturally, the brighter, the better. However, if you expect to use the projector where there's already a lot of room, this won't be as much of a factor.
• Contrast Ratio. This is the ratio between the image's brightest and darkest areas. Average is somewhere between 500:1 to 1200:1.
• Data Signal Ports. It's important that these are compatible with the image source with which they are paired.
• Keystone Correction: A good projector will have an ability to correct image distortion created when the projector is facing the screen at an angle other than 90 degrees.
• Video Format Capability: Don't get a projector if it does not accept the three main formats of PAL, SECAM and NTSC.

High Def LED Projector

With the advent of high-definition television has come also the high-definition LED projector. These projectors are capable of displaying images at an incredible resolution of 1080p. This makes the image very crisp and almost-life-like. Put simply, when you have a high-def LED projector, you have something capable of displaying film-quality images. You just can't go wrong.

Projection Screens

An LED projector is an outstanding choice for anyone who will be doing frequent presentations or lectures requiring visual aids. An equally smart choice is buying a projection screen to go with it. You can find these in various sizes and fabrics. Although it's possible to project your LED projector image onto a blank wall, it almost seems a waste. To get the best, crispest image, buy a good projection screen. The two working together provide an unforgettable visual experience.
