    Abstract: A multichip light-emitting-diode (LED) package includes a printed circuit board (PCB) having a tapered via hole and a circuit interconnection line on a surface of the PCB. An inclined surface of each via hole is used as a reflection plate reflecting light emitted by an LED chip located in the via hole. Each LED chip is directly bonded to a metal base for radiating heat. Additional heat radiation structures and reflection plates are not required, thus simplifying the structure of and manufacture of the multichip LED package, reducing manufacturing costs.

    Abstract: Each pixel region includes first and second pixel electrodes (17a, 17b) and first-third capacitor electrodes (67x-67z) each positioned on a layer where a data signal line (15) is positioned. One conductive electrode (9) of a transistor, the first pixel electrode (17a), and the second capacitor electrode (67y) are electrically connected with one another. Each of the first and third capacitor electrodes (67x, 67z) is electrically connected with the second pixel electrode (17y). The first-third capacitor electrodes are aligned in this order in a row direction in such a manner as to overlap a retention capacitor line (18) via a first insulating film, and the second capacitor electrode (67y) overlaps the second pixel electrode (17b) via a second insulating film. This allows increasing production yields of an active matrix substrate based on a capacitive coupling pixel division system and a liquid crystal panel including the active matrix substrate.

  • Publication number: 20110140133
    Abstract: The light intensity emitted from a package is increased by adjusting a portion of the package encapsulant so that light impacting the side walls of the adjusted encapsulant portion will encounter total internal reflection (TIR) with the reflected light directed toward the top surface of the package. The adjusted portion of the package is positioned so that air can be used as the second (exterior) medium with the critical TIR angle being such that light emitted from a light source (such as from an LED die) will be directed primarily so as to escape the package from the top surface as opposed to being scattered internal to the package. In one embodiment, a lower portion of the encapsulant is surrounded by a casing to inwardly direct light from the light source that impacts the side of the encapsulant with an angle less than the critical TIR angle.
