This standard BS IEC 62595-2-5:2021 Display lighting unit is classified in these ICS categories:
31.120 Electronic display devices
31.260 Optoelectronics. Laser equipment
IEC 62595-2-5:2021 specifies the measurement methods for measuring the optical characteristics of convex and concave cylindrical light sources. These non-planar light sources (NPLSs) can have either a continuous, distinct, segmented or block-wised light radiating surface, for example OLED panels, integrated LEDs, integrated mini-LEDs, micro-LEDs, laser diodes, each being either monochromatic or polychromatic.
