  • Patent number: 9595645
    Abstract: An LED device with improved angular color performance has a silicone lens shaped as a portion of a sphere. The lens is molded over an array of LED dies disposed on the upper surface of a substrate. Phosphor particles are disbursed throughout the material used to mold the lens. The distance between farthest-apart edges of the LED dies is more than half of the length that the lens extends over the surface of the substrate. The distance from the top of the lens dome to the surface of the substrate is between 57% and 73% of the radius of the sphere. Shaping the lens as the top two thirds of a hemisphere reduces the non-uniformity in the emitted color such that neither of the CIE color coordinates x or y of the color changes more than 0.004 over all emission angles relative to the surface of the substrate.

  • Patent number: 9530981
    Abstract: A method of sealing a flat panel display device by using laser and a charge-coupled device (CCD) camera. The sealing method includes applying a sealant around a light-emitting unit on a substrate and covering above the light-emitting unit with the encapsulating substrate; irradiating light onto a sealant area to harden the sealant for the first time (first hardening); monitoring a hardening state of the sealant; and further irradiating light onto a region of the sealant in a bad hardening state based on the monitoring result to harden the region of the sealant in the bad hardening state (second hardening). The sealing method may prevent a sealing flaw caused from insufficient laser irradiation dosage, and thus ensure a more stable sealed structure. This may improve quality of the flat-plan-display-device.
