Quality-Driven: Automotive Display Testing

Defect detection of in-vehicle displays presents a unique set of challenges. These displays will be viewed in widely varied lighting and must withstand harsh environmental conditions. Detection of subtle flaws that could worsen as a result of these circumstances is critical to ensuring a high quality display throughout the lifetime of the vehicle.

In this 45-minute webinar, Radiant presents:

  • Testing Considerations for Automotive Displays
  • Mura Detection
  • Testing to the Black Mura Standard
  • as defined by the German Automotive OEM Work Group Displays

Both automakers and suppliers to the industry will find this webinar informative.

Improving Automotive Inspection with Light & Color Measurement Systems

information about our surroundings, and infotainment displays enhance the driver and passenger experience. A vehicle's safety and perceived quality are increasingly contingent on the quality of light in these various displays, which must be measured to control the precise and meaningful variations in brightness and color. While standard machine vision systems can evaluate images for limited pixel-level contrast variations to detect defects, variations of light and color as perceived by humans are much too delicate for standard 2D imaging.

In this webinar, Radiant Vision Systems introduces light and color measurement solutions designed scientifically to evaluate light using the same perception tolerances as the human eye. Webinar host and Radiant's Automotive Business Leader, Matt Scholz, presents methods for using photometric and colorimetric cameras for brightness and color evaluation. In a conversational broadcast with Vision Systems Design's Editor-in-Chief John Lewis, Matt discusses the differences between machine vision and photopic imaging solutions, and defines the applications of light measurement used to evaluate components of today's illuminated vehiclesfrom tail lights to dome lights to displays.

During this webinar, attendees will learn:

  • How imaging photometers and colorimeters optimize light, color, and feature measurement in automotive lighting and displays
  • The advantages of photometric inspection over standard machine vision systems
  • Applications of light and color measurement in automotive components, from headlamps to HUD displays
  • How to choose an imaging system for your light measurement application

Audience questions are taken throughout the presentation and answered in discussion with the presenters.

Four Ways to Enable Automated SAE Standard HUD Measurement

criteria to assess HUD quality. The new standard (SAE J1757-2 “Optical Metrology for Automotive HUD”) will outline optical measurement geometries and requirements for determining HUD performance using light measurement systems. Although no single system is specified, there are several differentiating features among SAE-compliant systems that greatly reduce HUD evaluation time, enabling automated production-level measurement, ensuring compliance, and limiting cost and time to market.

In this 30-minute webinar, International Senior Business Advisor on Radiant’s Automotive team, Matt Scholz presents four key system features that offer the greatest technical advantages for SAE standard HUD measurement. Topics include:

  • Upcoming SAE J1757-2 standard and requirements
  • Key HUD measurement challenges
  • Camera features that ensure the fastest measurement setup
  • Software features that enable automated testing for production

An audience Q&A with the presenter follows the presentation.

Truly Automated Light and Color Measurement for Tell-Tales and Indicators

and the range of colors on an automotive display present a complex set of tasks for automated inspection systems and human inspectors alike.

In this 30-minute webinar, Radiant Product Manager Shannon Roberts presents Auto-POI—the latest technology for light and color measurement of multi-point inspection areas using an Imaging Colorimeter. This solution enables truly automated evaluation across entire instrument clusters. Topics covered include:

  • The fastest, most intuitive evaluation of complex instrument clusters
  • Applying automatic Points of Interest (POI) in software to measure all illuminated characters on a display at once
  • Toggle between programmed luminance and color thresholds to evaluate symbol sets for cross-symbol uniformity and harmonization
  • Automatically create accurate POIs even when displays are rotated or moved

The presentation is followed by an audience Q&A.

Evaluating Viewing Angle Performance Using Radiant’s Conoscope Lens

brightness and color remain consistent across LCD and OLED displays, even when embedded into assemblies or viewed at variable angles, manufacturers are seeking automated systems to control view performance from design to production. The challenge calls for a view angle measurement solution that is fast, easy to implement, and practical for in-line integration.

In this 30-minute webinar, Radiant Product Manager Bo Magluyan demonstrates the capabilities of Radiant’s new conoscope lens for measuring view angle performance of displays with greater speed, accuracy, and cost-efficiency as compared to competitive solutions.

  • Fast, accurate, low-cost view angle measurement solution
  • Address complex view angle challenges such as OLED color consistency and defects in embedded displays
  • Reduce the cost and complexity of equipment with a single, compact camera system
  • Use the same measurement system from R&D to in-line quality control, with ability to acquire additional measurements by switching camera lenses

A live audience Q&A follows a review of Radiant’s conoscope lens and a demonstration of the setup and use of the conoscope lens system for measuring a flat panel display.
