  • Ultraviolet LED light source and curing and packaging device and method for OLED device
    Patent number: 9899628
    Abstract: The present invention provides an ultraviolet LED light source and an device curing and packaging device and method. The ultraviolet LED light source (3) includes a PCB (31) and a plurality of ultraviolet LED lights (33) mounted on the PCB (31). The plurality of ultraviolet LED lights (33) is distributed in a longitudinal direction and a lateral direction of the PCB (31) to form an array. The PCB (31) includes a driving circuit corresponding to each of the ultraviolet LED lights (33) for controlling activation and deactivation of each of the ultraviolet LED lights (33) thereby achieving selective control of an illumination area of the ultraviolet LED light source (3). Using the ultraviolet LED light source to carry out curing and packaging of an OLED device may omit a masking plate and effectively protect an organic light emissive layer.
