CTOnews.com, January 20, according to a list of patents released by the U.S. Trademark and Patent Office (USPTO) today, Apple won a very technical patent for microLED screens on Wednesday on how to efficiently mass-produce microLED screens. Apple's patent focuses on technology, and it should be a long way from being put into commercial production.

CTOnews.com small class: the full name of MicroLED is Micro Light Emitting Diode Display, which is literally translated into LED display. Its display principle is to thin film, miniaturize and array the LED structure design of red, green and blue.

Compared with LCD, OLED and Mini LED,Micro LED, it not only has high refresh rate and low delay, but also has the advantages of high resolution, low power consumption and thin performance.

This patent describes the luminous structure and many methods for forming the luminous structure.

In one embodiment, a method for forming a light emitting structure includes forming one or more LED test sheets (coupons) on one or more corresponding temporary substrates, then transferring them to the carrier substrate to form a LED Mesa structure (mesa structures), and transferring the LED Mesa structure to the display substrate.

In some embodiments, a well structure (well structures) may also be formed around the LED Mesa structure before being transferred to the display substrate. In addition, the hybrid engagement can be used to engage to the display substrate. The processing sequence according to the embodiment may be used to form monochromatic and panchromatic displays.

In another embodiment, the light emitting structure includes a LED electrode pad bonded to a complementary metal oxide semiconductor (CMOS) substrate. LED electrode pads can contact pmurn diodes based on inorganic semiconductors and metal bottom contacts bonded to the electrode pads.

This patent involves very professional content, and there are a large number of professional technical vocabulary, the editor here is not clear about the specific benefits that these technical implementation cases can bring to the mass production of microLED screens. I beg your pardon, CTOnews.com.
