摘要:
A method for providing resource allocation in a communication network includes identifying at least two broadcast zones for receiving broadcast services in the communication network and generating a first index based on a relative relationship among the at least two broadcast zones. The first index includes information indicative of whether a first broadcast zone overlaps with at least one other broadcast zone. The method further includes generating a second index based on the relative relationship among the at least two broadcast zones; assigning at least one identifier to each of the at least two broadcast zones based on the first index and the second index; and enabling data transmissions to the at least two broadcast zones based on the assigned identifiers and using the at least one communication resource associated with the identifiers. The second index may include information indicative of a number of broadcast zones overlapped with the first broadcast zone. Each identifier may be associated with at least one communication resource, with distinct identifiers being assigned to overlapping broadcast zones of the at least two broadcast zones.

A backlight module includes a light source and a light guide plate. The light guide plate includes a light-receiving surface next to a light source, a light-emitting surface, and a light-reflecting surface oppose to the light-emitting surface. A plurality of notches are formed on the light-reflecting surface, and each notch has a first inner surface facing the light source and a second inner surface back to the light source and opposite to the first inner surface. The inclination angle of the first inner surface with respect to the light-reflecting surface is no more than 35 degrees.

An alternating current light-emitting device includes a substrate, an alternating current microdie light-emitting module, and a conductive structure. The alternating current microdie light-emitting module is formed on the substrate and has at least two microdies and a concave portion disposed between the two microdies. Each of the microdies has at least one active layer. The conductive structure electrically connects the microdies and thereby enables the active layers of the microdies to take turns to emit light during positive and negative half cycles of alternating current. The conductive structure is formed in the concave portion and covers an insulator. The present invention prevents undue open circuits but enhances yield.
