Due to these advantages, small size, low heat radiation, long life time, and high luminous efficiency, the light-emitting diodes (LEDs) have been used widely to the varied lighting in recent years. However, the LEDs have the higher intensity of light in central region and the scattering in the surrounding during lighting, so it is necessary to modify the LED projection by the secondary optical lens...
Because transparent conductive oxide (TCO) thin films have more than 80% transmittance in visible spectrum, and high electrical conductivity, the TCO films are widely applied to flat panel displays and solar cells as transparent electrode materials. This study aims to develop a direct patterning technology on ZnO:Al (AZO) thin films by a diode-pumped solid state ultraviolet laser. The electrode patterns...
