Two major LED technologies are employed in PRP’s device manufacturing plant – the assembly of individual LED chips to form a ‘hybrid’ structure that can be large in area, and the processing of a single substrate monolithic array of very small, high brightness emitting LEDs. While several standard products are available, a high proportion of the LED array products are custom-designed for specific applications.
The hybrid technology
The hybrid technology is used to make digital and analogue displays, using arrays that may contain many thousands of individual LEDs. The monolithic technology is employed to make LED arrays which can incorporate hundreds of individually addressable LEDs on a single chip. These arrays are used in avionics displays, instrumentation, optical systems, head-up displays, thermal imaging systems and also in commercial printing applications.
