Abstract: The present disclosure is directed to multicolored transparent displays. In some aspects, the systems and methods disclosed herein make use of light guides that operate on the principle of total internal reflection. Light can be extracted from the light guide by altering the interface at the surface of the light guide. A display can include a light guide having a plurality of pixels on a surface of the light guide. The display can also include a light source configured to introduce light into an edge of the light guide at a first angle greater than a critical angle for total internal reflection within the light guide, such that a portion of the light is extracted from the light guide by the plurality of pixels and is directed out of the viewing side of the display.

Abstract: A multiple line grid (MLG) for use in a multiple line grid array(MLGA) packaging incorporates therein circuit elements, e.g., metal lines, resistors, capacitors, inductors, transistors or combinations thereof, with a view to reducing a size of a printed circuit board on which it is mounted. The MLGA package includes a semifinished package including a surface with a first metal pattern formed thereon for connecting a number of input/output terminals, a printed circuit board(PCB) including a top surface with a second metal pattern formed thereon according to the first metal pattern; and at least of a MLG which is disposed between the semifinished package and the PCB. The MLG includes a non-conductive body incorporated therein a plurality of circuit elements and multiple number of conductors in the form of a column. Each of the conductors is electrically isolated from each other and is electrically connected to the first and the second metal patterns.
