In keeping with the newest report of 1Q17 Micro Media façade LED Curtain Screen next-generation show know-how market members by LEDinside, a division of TrendForce, the important thing know-how improvement path of Micro LED covers 4 elements, together with epitaxy and chip know-how, switch know-how, and bonding know-how (Bonding). , coloration scheme, and many others.
switch know-how
The core know-how of skinny movie switch is how you can seize numerous micron-scale skinny movie epitaxy. The present greedy strategies might be roughly divided into greedy strategies based mostly on bodily traits, or greedy strategies based mostly on chemical supplies. Taking bodily greedy for example, LuxVue adopts the strategy of attracting tiny elements by way of electrostatic power. The chemical greedy is represented by X-Celeprint, utilizing Elastomer Stamp because the medium, and van der Waals power for greedy. As well as, there are various producers who’ve developed many sorts of grabbing strategies.
One other core know-how of skinny movie switch is how to decide on the micron-scale skinny movie epitaxy that you simply need to seize. For instance, most of them use the dimensions of the seize power to manage the goal to be chosen. Or Van der Waals power, and select to use totally different ranges of vitality to the goal you need to seize. As well as, SONY additionally makes use of laser burning to pick particular targets.
Lastly, it’s typically used to attach the interior circuit of the LED chip to the substrate with a gold wire earlier than packaging and conduct the circuit. Nevertheless, for the reason that chip of Micro LED is just too small, there is no such thing as a method to mix it with the substrate by the same old metallic bonding methodology, so it wants to make use of different strategies to combine with the substrate. Subsequently, the long run know-how improvement will give attention to what sort of supplies are used for bonding and switch.
