Applications


The flexibility of MicroLED technology allow for a range of devices to be designed and built. These devices can be as simple as a single 20 um pixel emitter on a bare die or as complex as a large addressable array with integrated heat-sinking and control logic. 
Some of the applications of the MicroLEDs are shown below. The applications have been divided into those which generally require a single pixel, a cluster or an addressable array:- although the requirements often overlap. 

If your application isn't listed please contact info@InfiniLED.com to discuss your requirements with our engineers.

Single Pixel 

Portable Diagnostic/Point of Care/Handheld Analytical Instruments 
Many portable analytical devices use light to interrogate the specimen of interest. Compared to a conventional LED, the MicroLED will extend the battery life/reduce energy consumption and reduce or eliminate optical component such as lens, collimators and filters due to the collimated, narrow band emission directly from the chip surface. The shape of the MicroLED can be custom designed to match the specimen being integrated and thereby eliminate waste light. 

Ultra-fast Optical Communications
The miniature emitting area of a MicroLED means that it can be switched at sub-nanosecond rates. When coupled with its high power efficiency and small package this provides that perfect opportunity for enhanced data transfer rates without the need for temperature sensitive, high threshold laser devices.

Very Low Power Visible Indicators
MicroLED have the lowest power consumption per visible unit of light, making them the ‘greenest’ LED available. A MicroLED is visible to the eye when drawing 0.030µA of current vs. a requirement of 100µA before a conventional LED is visible. This is an improvement of over 3,000 times. Energy scavenging approaches rather that batteries can be used to power such indicators.
This technology will shortly be featured in Spectra Photonics. Further information can obtained by contacting InfiniLED. 

Security and Authentication
The threat of counterfeit pharmaceuticals or copied products is very real. A MicroLED based Very Low Power Indicators (as described below) using novel power sources (other than batteries) to power the MicroLED can be integrated into the product packaging or a tamper proof label. This offers a new, novel, low cost and non copy-able solution to guarantee product authenticity. If the package or label is tampered with, the LED will no longer illuminate. Such a tamper proof approach cannot be copied or repaired once the label is broken.

Product Branding
Similar approaches to that described above for Security & Authenticity above can be used to give a new, eye-catching and low cost approach to product branding. The MicroLED can be shaped to reflect a product logo or brand.

Cluster


Displays and Light Guides
The MicroLED offers significant energy and battery life saving for LCD backlighting and other light guide applications due to the optimal coupling of the MicroLED into thin light guides.

Micro Projectors
Large area MicroLED substrates produce collimated and high power RGB illumination as required by micro projectors. The MicroLED solution requires less energy and hence improves the battery performance of the device. The collimated beam from the MicroLED chip also enables a shorter optical beam path. 

Endoscopy
The collimated beam from a MicroLED eliminates the need for optics and enables smaller illumination packages - ideal for putting a light source onto the proximal end of the endoscope. The more efficient light generation results in significantly less heat generation and reduces heating which can be a major problem in endoscope due to their defined mass.

Fibre-coupled Light Sources
Fibre coupled LEDs are used in a range of applications from data transfer to medical diagnostics. Fiber coupled MicroLED are available with significantly enhanced coupling efficiency relative to conventional LEDs, integrated filters, minimal form factor and ultra high switching speeds.

Miniaturised LEDs
The individual pixels of MicroLED can be used to illuminate areas of interest with maximum efficiency. This is most useful where the area of interest is less than 100 µm2.

Addressable Array


LED Printing
A high density MicroLED 1D array specifically designed and packaged as a printing head for LED Printers can also be produced, compete with optics and data interface in a 8" package for A4 printing.

Structured Light Microsopy
Confocal microscopy is an imaging technique that enhances contrast by rejecting out-of-plane light. It does this using complex optics and a spinning disk based light source. InfiniLED can greatly reduce the complexity, cost and required components by using a high density LED array where individual light segments can be switched on and off in sequence. Such arrays enable a novel and very different approach called 'structured lighting' to confocal architectures.
