A light-emitting system with partitioned space and light-transmitting substrate
A recently filed patent (Publication Number: US20230320128A1) describes a light-emitting system that includes several innovative features. The system consists of a light-transmitting partition member that separates a space from the outside environment. On this partition member, a light-transmitting substrate is placed, which serves as the foundation for multiple light-emitting units. Each unit comprises a light-transmitting first electrode, a light-reflective second electrode, and an organic layer positioned between them. Importantly, the second electrode extends beyond the end of the light-emitting unit towards the outer side.
One notable aspect of this system is that the light emitted from the light-emitting units is directed towards the side opposite to where the partition member is located. This design choice ensures that the emitted light is not obstructed by the partition member and can be effectively utilized. Additionally, the light can also be emitted to the exterior through the partition member, providing flexibility in the system's application.
The patent also specifies a requirement for the dimensions of the second electrode. It states that when the substrate's thickness is represented by 'd' and the width of the portion of the second electrode beyond the end of the light-emitting unit is denoted as 'W,' the condition d/2=W must be met. This condition ensures that the second electrode extends sufficiently beyond the end of the unit, allowing for optimal light emission and preventing any potential interference.
Overall, this patent presents a novel light-emitting system with a unique configuration of light-emitting units and partition members. The system's design allows for efficient light emission both towards the opposite side of the partition member and through it to the exterior. The specific dimensions of the second electrode ensure optimal performance and prevent any potential issues. This patent could have significant implications for various industries that rely on light-emitting systems, such as lighting, displays, and signage.
