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. A new take on traditional display test methods (components and applications) may be all that is required to ensure curved displays can be quantifiably and objectively measured for visual quality. As an effective method is formalized, standards bodies can begin to define universal evaluation criteria, thereby allowing manufacturers to successfully incorporate new display form factors at a level of quality that is consistent with existing expectations. This webinar hosted by Chris Williamson, Sales Engineer at Radiant Vision Systems, 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 defect detection in curved displays. Recommended system settings are given for each method, as well as an overall recommended method and system. Topics include:
- Effects of display curvature on visualization of defects like pixels and lines
- Factors that impact defect detection:
- Measurement system resolution and depth of field
- Measurement setup (number of images and analysis regions)
- Optimal measurement methods for curved display testing
An audience Q&A with our presenter will follow the presentation.
