Ergonomics testing

To improve operability and safety with considerations for environment, the following evaluations and measurements are performed according to ergonomics standards:

  1. Measure the brightness of characters displayed on the screen (and the background) to check sufficiency of contrast ratio.
  2. Measure the coordinates of displayed colors to check the appropriateness against the values specified in applicable standards.
  3. Check the contrast ratio and color visibility change according to the light reflected when an additional light is irradiated on the screen
  4. Measure the static electricity on the screen and the intensity of electric and magnetic fields around the display
  5. Measure the power consumption
