    摘要： Disclosed is a method for fabricating an LED module. The method includes: constructing a chip-on-carrier including a chip retainer having a horizontal bonding plane and a plurality of LED chips in which electrode pads are bonded to the bonding plane of the chip retainer; and transferring the plurality of LED chips in a predetermined arrangement from the chip retainer to a substrate by transfer printing. The transfer printing includes: primarily section-wise exposing a transfer tape to reduce the adhesive strength of the transfer tape such that bonding areas are formed at predetermined intervals on the transfer tape; and pressurizing the transfer tape against the LED chips on the chip retainer to attach the LED chips to the corresponding bonding areas of the transfer tape and detaching the electrode pads of the LED chips from the chip retainer to pick up the chips.

    摘要： An LED display module is disclosed. The LED display module includes a substrate; a plurality of multi-pixel packages arrayed in a matrix with rows and columns, respectively, each of the multi-pixel packages including a package substrate and two or more pixels located on the package substrate and each of the pixels including a red LED chip, a green LED chip, and a blue LED chip; and a driver IC adapted to independently control the pixels of the multi-pixel packages. Anode terminals of the LED chips in the pixels adjacent in the row direction are connected in common to one another such that the pixels are scanned in rows in response to scan signals.
