  • Patent number: 9257618
    Abstract: The present invention provides a Light Emitting Diode (LED) package, comprising a Printed Circuit Board (PCB), an LED mounted on the PCB, a pillar placed higher than the LED around the LED on the PCB, a transparent plate disposed on the pillar, spaced apart from the LED, and configured to transmit light emitted from the LED, and a fluorescent layer formed on a surface of the transparent plate, facing the LED, and conformably coated with a substance for converting the light emitted from the LED into white light by changing a wavelength of the light, wherein an electrical pad of the LED and an electrical pad of the PCB are electrically connected to each other, and the LED and the fluorescent layer are spaced apart from each other.

  • Patent number: 8975808
    Abstract: Embodiments of the present invention provide light diffusion into edge lines of a modular display, and thus provide a modular display that is capable of displaying a single, continuous image without visible edge lines between individual display modules. One display module includes a multitude of pixels that contain red, green, blue, and white light sources. The replacement of an edge line blocking dam with the light diffusion edge line of the individual display module can provide a single, continuous image to be displayed thereon without visible, image-quality-reducing edge lines. With various heights of the buffer layer, the light can concentrate on the edge line in modular display. The individual display modules can be light emitting diode (LED), organic LED (OLED), UV LED, RGB LED, Phosphor-based LED, Quantum dot LED, or displays based upon a combination thereof. Furthermore, the variable height buffer layer allows for a modular display image in 2-dimensional or 3-dimensional formats.
