Rectangular LED, also known as rectangular light-emitting diode, is a type of LED that has a rectangular shape. With the continuous development of LED technology, rectangular LED has become an indispensable component in various fields such as lighting, display, and automotive. This article will introduce the development history, application fields, and future trends of rectangular LED.

Development History of Rectangular LED

LED, as a semiconductor device, has been widely used in various fields due to its low power consumption, long life, and high brightness. The development of rectangular LED can be traced back to the 1960s. At that time, researchers began to explore the use of gallium arsenide (GaAs) as a semiconductor material to produce light-emitting diodes. With the continuous optimization of semiconductor materials and manufacturing processes, the brightness and stability of LED have been greatly improved. In the 1980s, the emergence of high-brightness LED technology made rectangular LED widely used in the field of lighting.

In the 1990s, with the continuous development of display technology, rectangular LED began to be used in display screens. At this time, the application of rectangular LED in display screens was mainly based on the technology of liquid crystal display (LCD). With the continuous optimization of LED technology, rectangular LED has gradually replaced LCD in the field of display screens, and has become an important part of modern display technology.
