What Is A LED Projector?
LED projectors a gaining a lot of buzz lately because of how swiftly the technology works. Instead of using the traditional halogen lamp that most of the old projectors use, they use of 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 the human life better and easier.

What Is A LED Projector?
LED projector is a device that uses light-emitting diodes to project video content on a flat screen. It guarantees top class picture quality to users. Moreover, it eliminates the use of old halogen lamps for projecting content. iCodis combines the functionality of LED projectors in small pocket-sized devices. These devices are further enhanced with many other attributes such as their ability to provide live streaming options and Android application access to users. The productivity level of these LED projectors is commendable and is bound to impress you at the first impression itself. With the use of these devices, you can stream as well as project your favorite music videos, videos, TV shows, movies and many other files on a flat screen on the go.
The days of carrying large boxed projectors are headed for extinction. All the credit for the situation goes to iCodis for developing pocket-sized dynamic LED projectors that are comparatively more functional, productive and foremost portable. Say goodbye to wires and space-eating devices and welcome to the new technological brilliance of iCodis that is packed in these LED projectors.
Uses of LED Projectors
- Office Purpose
LED projectors can become your best office co-worker, allowing you can take this device with you for preparing mock presentations before going in meetings. Having a little practice with your projector is going to help you in building confidence and let you feel comfortable when you actually present your data in meetings.
The world is heading towards a wireless world, and these LED projectors are a pathway of going to that particular space. These wireless LED projectors have a high demand in the market due to their portable nature. The elimination of cables and largely boxed projectors in favor of more portable and efficient projectors is important to the future of tech.
- Watching Video Content on a Big Screen
Reliving moments such as wedding videos or family videos on television is becoming outdated lately. Why settle for a smaller screen when you can watch the similar video on a big screen with the aid of LED projectors? Additionally, you don’t need to settle for a smaller screen for watching movies either. Having a theatre-like experience using these LED projectors will allow you to live the moment instead of just watching it.
- High Functionality with Additional Services
These LED projectors are equipped with a built-in Android OS. Thus, you can gain access to Android applications on the device. These Android applications specifically include YouTube, Miracast and other video streaming apps that allow users to stream video content such as TV shows, movies, etc. on the go. The functionality of these LED projectors is incredible and never ending.
These reasonable LED projectors are powerful enough to enhance your gaming experience. Take these affordable, pocket-sized devices with you wherever you go. Use the ports to connect your console to the projector and enjoy the world class gaming experience. Say no to large TV sets, buy a LED projector and play games like a king.
Types of LED projectors
- 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.
- 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.
- 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.
- 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 is 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. 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 colour wheel acts as a medium with which small mirrors control the colour of pixels. The wheel splits into primary colours. These colours mix and the needed colour is projected on the designated pixel.
- Liquid Crystal on Silicon (LCoS): LCoS technology also uses 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 casted 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 sub pixels to project video content. These pixels have primary colors that cast colour on pixels. Field Sequential Color (FSC- LCoS) on the other hand split the input image into three main divisions of the existing three primary colours: 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 white light source. Optical principles are used to coalesce 3 different primary coloured 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.
