Spectral imaging systems refer to a class of imaging technology that captures and processes information about the wavelength of light within an image. These systems are designed to capture multiple bands or channels of information across the electromagnetic spectrum beyond the visible light that our eyes can see. This data can then be processed to generate a color-coded representation of the spectral data, which can provide information about the chemical and physical properties of the objects within the image.

Hyperspectral imaging is a powerful technology combining spectroscopy with imaging capability. It enables gathering detailed information about the composition and characteristics of objects and surfaces in a way that is impossible with conventional imaging systems.

Spectral imaging is imaging that uses multiple bands across the electromagnetic spectrum. While the RGB camera uses three visible light bands (red, green, and blue) to create images, hyperspectral imagery makes it possible to examine how objects interact with many more bands, ranging from 250 nm to 15,000 nm and thermal infrared. The study of light–matter interaction is called spectroscopy or spectral sensing. To learn more, read our article How does spectral sensing work?

E3 Displays has developed numerous adhesives that out-perform commercial grade urethane acrylates, epoxies, and silicones in UV aging tests. In an independent side-by-side solar aging test, E3’s proprietary optical adhesive out-performed all other bonding agents regarding color shift and adhesive degradation.

Optical bonding services reduces the internal reflections between the LCD and cover substrate (glass, plastic, filter, touch panel) since the optical bonding adhesive creates a matching refractive index between the LCD and substrate. Reducing internal reflections increases the contrast and viewability, which enables displays to be more readily seen in bright ambient conditions (such as outdoor sunlight), without increasing backlight brightness and the accompanying higher power and operating temperatures.

One of the key benefits of hyperspectral imaging is its high spatial and spectral resolution which enables the detailed characterization of the materials.

LOCA is used in an optical bonding process where the air gap between the touch display and cover lens is filled. This adhesive is cured using UV light instead of heat. This edge-to-edge bonding process allows for increased viewability, touch sensitivity, and sunlight readability. It increases display durability and prevents moisture from building up between the touch panel and cover lens.

A combination of LOCA and OCA optical bonding. The liquid optically clear adhesive is dispensed to a touch sensor, next to the touch sensor and display are sealed together in a vacuum chamber, then the entire display is cured under UV light. This method of optical bonding provides the same benefits but is used with only certain display applications.

Heat dissipation is the key to measuring display performance. The heat generated by the operation of the display is dissipated through optical material and is not blocked by insulating air layers. By filling the insulating air gap between the components, heat can be transferred to the outside environment.

Compared to multispectral imaging, hyperspectral imaging provides more information allowing for more accurate analysis, identification, and separation of materials and substances (To learn more, read our article Hyperspectral vs. Multispectral cameras).

By combining the benefits of digital imaging and a spectrometer, hyperspectral imaging provides both spatial and spectral information about the object’s physical and chemical properties. The spectral information allows for the identification and classification of materials and the spatial provides data on the material’s distribution and areal separation. Hyperspectral imaging provides answers to questions concerning “what” (based on the spectrum), “where” (based on location), and “when”.

Thanks to its noninvasive, and nondestructive capability in identifying and quantifying material, hyperspectral imaging has become increasingly popular in various industries and research applications.

Traditional optical bonding touch screen configurations are only bonded from the sides and leave a massive gap in the middle that allows dust, dirt and moisture to get in and destroy the display from within. The optical adhesive fills the gap between the substrate layer and LCD, preventing contaminants from impacting the display viewability. Condensation or impurities can render the display unreadable.

The result is a hyperspectral image, where each pixel represents a unique spectrum. This unique spectrum can be compared to fingerprints. Since every material and compound reacts with light differently, their spectral signatures are also different. Just like fingerprints can be used to identify a person, the spectra can identify and quantify the materials in the scene.

Optical Bonding is an effective means of improving resistance to shake and shock environments – a benefit especially useful in harsh military and transportation environments.

The electromagnetic spectrum describes all types of light, ranging from very long radio waves, through microwaves, infrared radiation, visible light, ultraviolet rays, and X-rays, to very short gamma rays — most of which the human eye can’t see (Figure 1).

A hyperspectral camera captures a scene’s light, separated into its individual wavelengths or spectral bands. It provides a two-dimensional image of a scene while simultaneously recording the spectral information of each pixel in the image.

Optical bonding services dramatically increases both physical durability and impact resistance. Unlike traditional, unprotected LCDs, optically bonding for displays can have a cover glass that protects the display from rain, dust, snow, hammers, screwdrivers, etc. Adding custom cover glass, touch screens, optical filters, optical coatings, and other enhancements with optical bonding displays creates a durable and complete rugged solution.

The process of applying adhesive tape to the edges of a touch panel that allows the cover lens to be bonded to the display. This process leaves an air gap between the touch panel and display cover lens. This process increases glare and reflections while also leaving the display susceptible to moisture and impact damage.

Hyperspectral imaging is a technique that collects and processes information across the electromagnetic spectrum to obtain the spectrum for each pixel in an image. This allows for the identification of objects and materials by analyzing their unique spectral signatures. Applications of hyperspectral imaging include food quality & safety, waste sorting and recycling, and control and monitoring in pharmaceutical production.

Additionally, the air gap layer is encapsulated with adhesive and cured, preventing dust and foreign particles from entering or shifting within the display area . Heat dissipation, through the front glass, is also improved. For applications like military, marine, medical devices, outdoor use and more, optical bonding for displays is a great way to improve display performance and offer additional protection as well.

A hyperspectral camera measures thousands or hundreds of thousands of spectra to create a massive hyperspectral data cube comprising position, wavelength, and time-related information.

The data provided by hyperspectral imaging systems can be used during inspection to locate, sort, or quantify the concentration of various materials that are invisible to common cameras or the human eye. For instance, a hyperspectral imaging system integrated into an in-line quality control system enables the identification of foreign objects, contaminants, and the amount of fat, sugar, or moisture in products.

Hyperspectral imaging involves using an imaging spectrometer, also called a hyperspectral camera, to collect spectral information.

Hyperspectral imaging system analyzes a spectral response to detect and classify features or objects in images based on their unique spectra.

In conclusion, hyperspectral imaging is both a prominent tool for research and highly useful machine vision technology for various industries to improve processes, increase quality, and reduce waste.

OCA is applied using a process similar to film lamination. Unlike LOCA, OCA is an adhesive sheet that is placed between the touch panel and the cover lens. This adhesive is cured using pressure and heat inside of an autoclave. This method allows for thinner bond lines and is ideal for thinner, more compact applications.

Optical Bonding is going to dramatically improve any display. However, a main benefit of optical bonding is sunlight readability and ruggedization which means that military, avionics, and marine commonly use optical bonding in their displays.

E3 Displays bonds exclusively with E3 Materials urethane acrylate adhesives. These chemically engineered formulations designed specifically for the display market from E3 Materials have been benchmarked against the competition, and proven to be the best in the industry for 10+ years.

Figure 2: To match human vision, a digital photograph of a leaf (top) is created using three bands: red, green, and blue. The RGB data is comparable to a three-page pamphlet. In contrast, a hyperspectral image of a leaf (bottom) captures a spectral response from 220 wavelengths. The comparable 220-page book contains much more detailed information about the object.

Display models offer a variety of product offerings including transflective displays, super-narrow bezels, to completely bezel-less TFT cells. The market has demanded a wide array of displays, why would you only use one type of adhesive? After careful evaluation of numerous commercial materials (silicones, epoxies, urethane acrylates), E3 Displays determined that while UV curable urethane acrylates offered distinct mechanical and process advantages over silicones and epoxies, these commercially available adhesives did not meet the technical performance criteria essential for use in the harsh environments of avionics and military products. This being the case, E3 displays chose to develop a family of custom adhesive formulations whose overall performance exceeds that of competing materials and are tailored to meet varied product requirements. After thousands of hours of development and testing, E3 Displays has created unparalleled adhesives in optical bonding services which are application (and display) specific.
