EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62595-2-5 testing. IEC EN 62595-2-5 specifies measurement methods for measuring the optical properties of convex and concave cylindrical light sources. These non-planar light sources (NPLSs) emit a continuous, discrete, segmented or block-shaped light, such as OLED panels, integrated LEDs, integrated mini-LEDs, micro LEDs, laser diodes, all of which are monochromatic. may have a surface.
The recent introduction of curved OLED TVs and the anticipated rapid spread of flexible displays in portable devices highlight the need for new measurement methods. In recent years, flexible displays, mobile phones and wearables have been integrated into products. The development and integration of flexible displays has increased the applications of curved devices, such as discrete or curved large-size wall displays, foldable signage displays, and commercial wearable or handheld devices. Measurement of optical properties of screens with a radius greater than 35 mm has been documented.
Since the properties of a non-planar light source (NPLS) change with decreasing radius of curvature, optical properties of the LS such as lateral and directional luminance and luminance changes, lateral and directional chromaticity distributions and their variations, luminous intensity distribution, and luminous flux will be measured and evaluated.
This standard specifies measurement methods for cylindrical light sources that can serve as the basis for non-planar LS study, which is assumed to be an integration of small areas. The key element of such a surface may be a first-radius convex or concave curvature, ie a cylindrical shape worthy of consideration in this document.
