In today’s automobiles, versatile high-resolution touchpads have replaced analog gauges and knobs. Modern smart lighting adjusts to changing conditions. Radios have been replaced with multi-function, touch-sensitive infotainment displays. Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies. Head-up displays (HUDs) are becoming an automotive standard.
My blog a few weeks ago took a dive into the world of automotive freeform displays, and discussed how these novel shapes have given auto- and panel-makers the ability to freely design displays into any integration space.
With all the places you find digital displays these days, evidence suggests it might not be that hip to be square. Displays that break the mold of the standard rectangular, flat-panel design enable a highly organic integration of display features into shapes and sizes that are a much better fit with their use and environments.
LEDs remain a pivotal light-emitting element in a range of lighting products and displays. For manufacturers of these devices, it is important to evaluate the performance of LEDs and LED-based systems in objective and meaningful ways.
Emissive OLED, microLED (μLED), and miniLED are emerging as the next wave of technology in the display market. This is exciting because these displays promise improved display performance and visual appearance with greater efficiency than other display technologies, thanks to their individually emitting pixel elements. However, high costs due to material prices and manufacturing yield issues have hindered widespread technology adoption for these displays.
In this webinar, the Radiant Vision Systems Automotive Team presents effective solutions for evaluating the quality of curved and freeform displays. The team discusses the challenges posed by these displays for measurement, and introduce the latest solutions from Radiant for display registration and flexible measurement setups.
Display uniformity is important for visualization of digital information, but perhaps nowhere is this more critical than in industries where displays are relied upon for vehicle operability and safety. Automotive display quality is rigorously tested to ensure visibility—not only to safeguard a positive brand perception, but to comply with industry regulations.
As display resolutions increase, imaging systems are challenged to continue to provide accurate pixel-level measurements while applying increasingly limited relative imaging resolution during single-image analysis (necessary for production efficiency). A fractional pixel registration and measurement method improves the accuracy of pixel-level values measured by standard-resolution systems, ensuring effective qualification and demura of high-resolution OLED, miniLED, and microLED displays.
OLEDs (Organic Light-Emitting Diodes) are emerging as the next wave of technology in the flat-panel display market. This is exciting because OLED displays promise improved display appearance for both smartphones and large-format TVs at lower cost and power than other display technologies.
Augmented, virtual, and mixed reality (AR/VR/MR) devices and other head-mounted displays (HMDs) are unique in the display industry as they are intended to be viewed at very close range. Unlike televisions seen from across a room, or smartphones held at arm’s length, these appropriately named Near-Eye Displays or Near-to-Eye Displays (NEDs) are typically positioned a mere 1.2 - 3 inches from the user’s eye.
Organic light-emitting diodes (OLED) and microLEDs (μLED) are emerging as the next wave of technology in the display market. Display screens based on these emissive layers promise improved performance and visual appearance with greater efficiency than other display technologies, thanks to their individually driven pixel elements.
Take a look at the basic operating principles and performance tradeoffs of imaging colorimeters, a class of instruments that enable spatially resolved measurements of color and luminance that are directly applicable to displays and solid-state sources.
FPDisplay sits with Radiant Technical Director, Li Sun, during the 8th China Information Technology Expo (CITE 2020) in Shenzhen to understand how Radiant continues to innovate in step with—and ahead of—the display market.
Every light source in a vehicle must be measured to ensure its effectiveness for its application. Headlamps must adhere to roadway illumination standards for proper beam shapes, distributions, and intensities for illuminating areas outside the vehicle. Inside the vehicle, LED-backlit components rely on consistent brightness and color—as well as cross-component harmonization—to convey a vehicle’s quality in both function and aesthetic.
Curved displays offer manufacturers new design flexibility for vehicle interiors, but also introduce challenges for display measurement. This paper presents the results of several lab tests measuring a 1500R LED-lit curved display using an imaging colorimeter and analysis software to evaluate the effectiveness of various methods and system specifications to optimize the accuracy of small defect detection (pixels and lines) in automotive curved displays.
Curved displays offer manufacturers new design flexibility for vehicle interiors, but also introduce challenges for display measurement. Display test methods developed for traditional flat panel displays are inadequate for accurately evaluating the visual qualities of curved displays, which are affected by view angle changes along their curvature that result in focus and contrast differences from center to edge.
This year’s Nobel Prizes in physics were announced on October 2. The three recipients include American Arthur Ashkin, at 96 the oldest Nobel Laureate, for his work developing “optical tweezers.” The other 2018 recipients are Frenchman Gerard Mourou and Canadian Donna Strickland—only the third woman in history to ever receive the Nobel for Physics—for their work with pulsed lasers.
Radiant Vision Systems provides leading display test solutions for labs and production lines, with thousands of cameras testing millions of devices worldwide.
Evaluating the visual quality of displays as viewed through augmented and virtual reality headsets requires testing from the vantage point of the user. Radiant Vision Systems provides a comprehensive hardware/software solution designed to replicate viewing parameters within AR/VR headsets for the most accurate and efficient evaluation of displays and projections.
As the world is adjusting to new pandemic realities, so too is the display industry. The focus was on displays last week, as the Society for Information Display (SID) held its first all-virtual Display Week symposium and tradeshow.
