In the development of blue LED chips, Toshiba has a blank space and started late. To catch up with other companies that have been successful, Toshiba needs to work harder. LED chips account for a significant portion of the cost of LED lighting, and Toshiba plans to implement internalization.
Currently, approximately eight gases are typically used in the manufacture of LED chips. The crystal growth conditions of an MOCVD apparatus in which one of the gases is used to manufacture the LED chip are constantly changing. To this end, Toshiba will make detailed adjustments and improve the equipment by yourself.
Careful adjustment is also essential to reduce the energy loss of the LED. At present, in the power input to the white LED, only about 20% of the total energy can be used as the light energy. Toshiba plans to develop technologies that will increase this efficiency.
