Machine vision has begun to overlap with augmented and virtual reality. Not only does machine vision provides pivotal environmental and user information to the AR/VR system, these technologies are also cooperating to enable enterprise operations in industrial manufacturing, assembly, design, and training. New entprise AR/VR applications are bringing together camera systems, near-IR eye tracking, gesture recognition, and other machine vision capabilities.

To compete with the superior contrast ratio performance of OLED display screens, LCD makers have developed the technique of local dimming, which allows different regions of a backlight to be controlled independently. The introduction of miniLEDs for LCD backlights, especially in full-array configuration, is boosting the performance of LCD televisions and display screens.

The ultimate measure of display's performance is how it appears to a human viewer. While all of the typical electronic display metrics—ppi, refresh rate, luminance, pixel pitch, etc.—are informative, being able to measure and grade display defects using the Just Noticeable Difference (JND) method is key for display manufacturers to ensure quality.

MicroLED displays offer superior performance for brightness, contrast, and energy efficiency compared to OLED or other existing display types, but so far production challenges have held them back from mass commercialization. Manufacturers are rapidly closing the gap, however, and microLED display products could be coming to the general consumer market soon. We look at microLED technology and ways to overcome quality challenges.

The development of medical imaging technologies—such as X-ray, MRI, CT, ultrasound, and PET—has revolutionized healthcare. To view images accurately, display screens used by radiologists, surgeons, and other clinicians must provide higher performance than commercial-grade screens. Learn about medical-grade display requirement and quality assurance solutions.

Ever since Princess Leia's holographic emergence in 1977, developers have been trying to create 3D volumetric holograms like those in Star Wars and other science fiction movies. Many of what we call "holograms" today appear three-dimensional, but are actually just images projected onto a flat screen—technically still 2D. But new developments are making 3D holograms that you can view from every angle a reality.
