Abstract
Thanks to the development in epitaxial growth, chip fabrication and packaging of LEDs, emission spectral of the device is capable of covering the visible spectrum. Therefore, Light-emitting diode (LED) is currently undergoing a growing interest in many applications, such as lighting. Besides lighting, LEDs offer a wide range of potential applications including display. In contrast with LCD, LEDs display has better contrast ratio, higher response rate etc which makes LEDs along with other self-illumination technologies an ideal candidate in making display panel. Due to the popularization of HD and Ultra HD standard, display panel with better image quality is needed which means the number of pixels of the panel needs to be increased while the size of each pixel needs to be minimized. In this paper, we describe the design and fabrication of a colour tuneable and addressable LED micro display based on a 16×16 and 32×32 LED matrixes with typical pixel size of 0.7 and 0.5mm respectively.
