As the field of microLEDs continues to advance, many engineers are focusing their attention on External quantum efficiency (EQE). EQE is a critical measurement for microLED testing and development because it determines the efficiency of microLEDs in converting electrical input power into optical output power. MicroLEDs are a promising technology for use in displays and lighting applications because of their small size, high brightness, and low power consumption. However, in order for microLEDs to be competitive with other technologies, it is important that they have a high EQE.
There are several reasons why high EQE is important for microLEDs. First, high EQE allows for the production of bright, high-quality images with low power consumption. This is especially important in portable devices, such as smartphones and tablets, where battery life is a key concern. By increasing the EQE of microLEDs, it is possible to achieve the same level of brightness using less power, which can lead to longer battery life and lower energy consumption.
Second, high EQE is important for the cost-effectiveness of microLEDs. The cost of producing microLEDs is largely determined by the efficiency of the manufacturing process. By increasing the EQE of microLEDs, it is possible to reduce the number of defects and improve the yield of the manufacturing process, which can lead to lower production costs. This is especially important in the development of large-scale microLED displays, where the cost of producing each individual microLED becomes a major factor.
Finally, high EQE is important for the environmental sustainability of microLEDs. The energy used to power displays and lighting systems is a significant contributor to greenhouse gas emissions. By increasing the EQE of microLEDs, it is possible to reduce the amount of energy required to produce the same amount of light, which can lead to a reduction in greenhouse gas emissions.
In a word, EQE is a critical measurement for microLED testing and development because it determines the efficiency of microLEDs in converting electrical input power into optical output power. High EQE is important for the production of bright, high-quality images with low power consumption, the cost-effectiveness of microLEDs, and the environmental sustainability of microLEDs. As a result, measuring and improving the EQE of microLEDs is an important aspect of microLED testing and development.
