TT-AutomotiveDisplay™ Automotive Display


TrueTest™ Add-on

Automotive displays face particular demands for performance through variable lighting conditions, temperatures, vibrations, viewing angles, and other factors. Ensuring visual quality of displays of various shapes and sizes, with anti-glare or anti-reflective coatings, integrated into different fixtures and at fixed positions relative to passengers and drivers, is a key challenge for manufacturers in the increasingly display-focused automotive market.

Part of the Radiant Vision Systems TrueTest™ Software family, the TT-AutomotiveDisplay module provides all of the benefits of TrueTest Software to efficiently perform light, color, and mura measurements with specific tests to evaluate the quality of displays integrated within the vehicle. A comprehensive automotive display test solution from Radiant combines the TT-AutomotiveDisplay application-specific software module and a ProMetric® Imaging Colorimeter or Photometer to perform rapid, automated visual inspection of displays from consoles to panels to center stacks.

TT-AutomotiveDisplay relies on a ProMetric imager to test all display characteristics simultaneously, capturing and processing data much faster and more consistently than a human inspector or a spot measurement device.

Validation Testing for In-Car Displays

TT-AutomotiveDisplay provides a suite of common photometric software analyses used to evaluate automotive displays for visibility in all ambient lighting conditions (accurate luminance and contrast), seamless quality (uniformity and mura analysis), and absence of defects that may have resulted during assembly or integration stress (stuck on/off pixels, lines, embedded particles, and other anomalies). TT-AutomotiveDisplay tests can be used for specialized display validation needs:

  • Evaluate luminance (minimum and typical), straight-on or off-angle, in DAY or NIGHT mode

  • Document cold startups and contrast ratios (minimum and typical) over a wide FOV

  • Measure color coordinates and tolerances for White, Red, Green and Blue test inputs

  • Test for maximum allowable reflection


Black Mura

Developed by the “German Automotive Work Group Displays” standard body and published by the German Flat Panel Display Forum (DFF), the Black Mura Standard is a standard measurement method for evaluating uniformity in automotive displays. TT-AutomotiveDisplay provides tests for Black Mura Gradient analysis, with an API for synchronized control of display test images and automated test sequences for rapid visual testing. Radiant’s automotive solutions team provides guidance around standard methodology for display alignment and test setup to ensure compliance with Black Mura test procedures.

  • Black Mura Defocus: Remove anti-aliasing moiré effects from the display image

  • Black Mura PWM: Test pulse width modulation (variation in luminance between measurements at the center of the display)

  • Black Mura Gradient: Test maximum gradient relative to a white and black test pattern
