In　this　paper,　a　high-pixel　micro-LED　chip　array　was　prepared　based　on　a　blue/green　multi-quantum　well　LED　epitaxial　chip　based　on　gallium　nitride　on　sapphire　substrate　by　using　mature　LED　chip　technology.　Metal　protruding　points　were　designed　and　prepared　on　the　surface　of　both　micro-LED　chip　and　CMOS　driver　chip,　and　good　bonding　between　LED　display　chip　and　CMOS　driver　chip　was　achieved　by　adopting　high-precision　inversion　welding　process,　and　micro-LED　display　with　resolution　of　640×360　was　successfully　prepared.　At　the　same　time,　the　driver　system　of　micro-LED　display　was　designed　with　FPGA　as　the　controller.　Then　the　driver　system　can　cache　the　input　image　data　and　process　it　into　monochromatic　image　data　which　can　be　received　by　the　display,　and　finally　writes　the　processed　image　data　into　the　driver　chip　to　realize　the　image　display.　©　2020,　Editorial　Office　of　Semiconductor　Optoelectronics.　All　right　reserved.
