Consumer Electronics

Electronic devices use color and light to convey digital information to users via illuminated controls and high-resolution displays. The use of display-based technologies has extended beyond televisions, computers, and phones to appliances, toys, wearables, and other devices. The visual quality of these products not only enables functional operation but defines the customer experience and satisfaction. Device designers and manufacturers must meet ever-increasing consumer expectations for exquisite display quality.

Radiant Vision Systems applies decades of experience in automated visual inspection at all stages of the design and manufacturing process, leveraging our history in light and color measurement and our expertise in production-level display test solutions. We support major consumer electronics manufacturers worldwide, and understand that a flawless device is a prerequisite for market success. We work closely with you to provide comprehensive solutions that support your operating imperatives—increasing throughput, reducing rework, and achieving absolute quality.

Radiant’s TrueTest™ Software offers production-level quality control and an extensive library of tests. Our ProMetric® Imaging Colorimeters and Photometers feature advanced optical filters that simulate human visual perception of light and color, providing the truest evaluation of quality your customers will see. An integrated system from Radiant helps you to ensure that each device meets your standards at every stage of manufacture – and, meets your customer’s expectations in today’s competitive marketplace.

 

Leader in Display Testing

All Display Technologies from LCD to OLED

As the number-one provider of display test solutions worldwide, Radiant has thousands of systems currently deployed testing millions of smart devices, touchscreens, infotainment panels, embedded displays, and other display devices. A broad range of tests can be performed on LCD, OLED, and other display types using a Radiant ProMetric Imaging Colorimeter or Photometer paired with TrueTest™ Software, including:
 

  • ANSI brightness
  • ANSI color uniformity (CIE x, y and CIE u’,v’ coordinates)
  • light or color mura (blemish) detection
  • light leakage
  • pixel and line defect inspection
  • image sticking
  • view angle performance


Radiant’s automated visual inspection systems weigh and evaluate defects based on severity and scope, which correlate to either permissible or unacceptable imperfections as they would be perceived by a typical human observer. With scientific-grade, interline-cooled CCDs with up to 29-megapixels in resolution, ProMetric cameras capture high-resolution images in a single measurement while minimizing visual noise. This ensures that you have the clearest images for fine-detail and pixel-level defect inspection.

Keyboard Inspection Solutions

Radiant’s portfolio of inspection solutions includes software specially engineered for testing illuminated keyboards, keypads, and control panels in high-volume manufacturing environments. Using our automated visual inspection on the production line, you can ensure perfect final assembly of backlit keys and components, safeguarding device usability and ensuring long-term product quality.

ProMetric imaging solutions and the PM-KB™ Illuminated Keyboard Testing module for ProMetric Software let you apply unique tools for inter- and intra-character luminance and color uniformity and perform optical character recognition (OCR) to ensure keys are easily viewed and properly installed in their correct locations. OCR technology can also be applied to verify the accuracy of character print location or quality.

Cosmetic Surface Inspection and Assembly Verification

Scratched, dented, and otherwise imperfect products result in costly returns and may damage your brand’s reputation and future business. Quality control operations that are intended to prevent surface defects rely largely on human inspectors to ensure defective products are not shipped to consumers. However, the faster the production rate, more complex the product, or more obscure the defect, the more difficult it is for humans to keep up with throughput demands while maintaining consistent quality.

Our industry-leading technology for light measurement can be combined with select machine vision tools to accomplish challenging inspection applications of non-illuminated surfaces and components, including device covers and electromechanical assemblies. Radiant CCD systems capture high resolution images up to 29-megapixels. A large dynamic range to 73 dB captures the greatest range of grayscale values. These capabilities yield images with increased clarity and contrast and enable detection of fine details that typical machine vision systems miss (such as black screws on black material, or hairline measurements that indicate improperly placed parts or scratches on metal surfaces).

Our automated visual inspection solutions can detect, identify, and quantify defects for analysis without human intervention, enabling you to easily identify and apply automated pass/reject mechanisms to defects that fall out of defined severity tolerances.
