Abstract: A microLED display panel includes a substrate being divided into a plurality of sub-regions for supporting microLEDs, and a plurality of drivers being correspondingly disposed on surfaces of the sub-regions respectively. The driver includes a low-dropout (LDO) regulator and a drive circuit. The LDO regulator receives a system power, according to which a regulated power is generated and provided for the drive circuit.

Abstract: The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.

Abstract: A cascaded die mounting device and method using spring contacts for die attachment, with or without metallic bonds between the contacts and the dies, is disclosed. One embodiment is for the direct refrigerant cooling of an inverter/converter carrying higher power levels than most of the low power circuits previously taught, and does not require using a heat sink.
