methods to improve the birghtness of led displays

We can improve the brightness of led displays by the following two methods.

1. To increase the chip light output. The chip light output can be increased through improving the luminescence efficiency of the chips active layer or improving the external light extraction efficiency by optimizing chips shape or making larger scale chips that run high density current.

2. To use the light effectively. In other words, to increase the amount of light that irradiate towards the needed direction. In this method, light wave control technology is used. Through a better design of the optical structure shaped by the packaged epoxy resin, the light can be controlled to shine towards expected direction, thereby improving the brightness of LED.

LED display's brightness is very important for the users. However,the most important for a led display user is using led display by a right way. You'd better use a multifunction card with light dimmer to adjust the brightness. then you can save some energy and also use led display effiectively.
