ROHM recently announced the 1608-size high accuracy blue-green chip LEDs, SMLD12E2N1W and SMLD12E3N1W. These products support the adoption of Color Universal Design (CUD) in a variety of applications, such as fire alarm system indicator lights, industrial equipment warning lamps and public transportation information displays.
Color is considered to be one of the most important means of communication and is used in a variety of ways – daily. However, approximately over 200 million people with P-type and D-type color deficiencies around the world find it difficult to distinguish between red and green, possibly resulting in information being inaccurately conveyed – depending on the combination of colors used. Furthermore, since color vision can vary from person to person, it is difficult to perceive how different people see certain colors, which can be very inconvenient and also problematic as other people may not notice this deficiency.
As a result, there is a growing need in the society to implement Color Universal Design that takes into account the various types of color vision in order to deliver information accurately to as many people as possible. ROHM succeeded in developing blue-green chip LEDs with special wavelengths. These products are ideal for implementing Color Universal Design in a wide range of devices, utilizing a vertically integrated production system from the element fabrication stage and leveraging ROHM’s strength thorough quality control.
