Image quality is a key feature of user experience for display devices. BS IEC 61747‑30‑5 is part of the BS IEC 61747 series on liquid crystal display (LCD) devices. BS IEC 61747‑30‑5 specifies the standard measurement conditions and measuring methods for determining the optical properties of transparent LCD modules which operate in a transmissive mode.
More specifically, BS IEC 61747‑30‑5 focuses on three particular aspects of the transparent properties, i.e. transmittance, haze, and image distortion.
BS IEC 61747‑30‑5 on transmissive transparent LCD measurement is applicable to:
BS IEC 61747‑30‑5 walks you through measurement conditions for the transmitted haze test which include environmental conditions, darkroom conditions, and measurement locations. Measurement methods of on-screen properties have been discussed in detail.
luminous transmittance, transmitted haze, colour shift, contrast ratio offset, sharpness, as well as MTF and Michelson contrast ratio. Contrast ratio and colour coordinates with the incident illumination originating from objects behind the screen is another method that has been discussed in detail.
Using BS IEC 61747‑30‑5 guidelines, you can assess the picture quality of the LCD display devices that you manufacture, and use those inputs to evolve newer products that enable end-users to enjoy high-quality display devices.
