Abstract
Abstract A semiconductor string connection structure comprising a plurality of encasements, each of which has a light emitting diode chip and a pair of conducting leads, a plurality of binding pieces connected between the encasements, a plurality of longitudinal pieces disposed between two pairs of the conducting leads or at the right-most or left-most side thereof, a plurality of transverse thin pieces connected with the leads and longitudinal pieces, and a transverse plate disposed and connected with lower ends of the leads and longitudinal piece. The transverse plate serves as a common line, therefore, the lower half of the semiconductor string connection structure is folded 180 degrees such that the whole structure can be mounted on a circuit board to form a large display.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
A semiconductor string connection structure comprising: a plurality of encasements, each of which encloses a semiconductor chip, and a plurality of conducting leads projecting parallel from one end thereof; a transverse plate integral with said plurality of conducting leads and disposed at an end opposite to the encasements; a plurality of longitudinal pieces, each longitudinal piece disposed between two pairs of said conducting leads and integral with the transverse plate; a plurality of stop pieces, integrally formed with the conducting leads and disposed at a midpoint of the conducting leads; a plurality of binding pieces integrally formed with the disposed between each encasement; a plurality of transverse thin pieces, integral with the conducting leads and/or the longitudinal pieces and disposed between the conducting leads and longitudinal pieces; and a plurality of positioning holes uniformly disposed along a length of the transverse piece.
Claim 2
Dependent Claim
142 words
A semiconductor string connection structure comprising: a plurality of encasements, each of which encloses a semiconductor chip, and a plurality of conducting leads projecting parallel from one end thereof; a transverse plate integral with said plurality of conducting leads and disposed at an end opposite to the encasements; a plurality of longitudinal pieces, each longitudinal piece disposed between two pairs of said conducting leads and integral with the transverse plate; a plurality of stop pieces, integrally formed with the conducting leads and disposed at a midpoint of the conducting leads; a plurality of binding pieces integrally formed with the disposed between each encasement; a plurality of transverse thin pieces, integral with the conducting leads and/or the longitudinal pieces and disposed between the conducting leads and longitudinal pieces; and a plurality of positioning holes uniformly disposed along a length of the transverse piece.
Claim 3
Dependent Claim
100 words
A semiconductor string connection structure as set forth in claim 1, wherein: the transverse thin pieces are cut away after fabrication; the binding pieces are cut away after fabrication; the conducting leads not intended to be collectively connected are separated from the transverse plate; the conducting leads attached to the transverse plate are folded 90 degrees twice, such that respective free ends of the longitudinal pieces are directed in a same direction as the free ends of said separated conducting leads; a plurality of longitudinal pieces are cut away after fabrication; and the lead frame is separable into various lengths.
Claim 4
Dependent Claim
30 words
A semiconductor string connection structure as in claim 1, wherein said encasement encloses more than one semiconductor chip and an additional conducting lead is provided for each additional semiconductor chip.
Claim 5
Dependent Claim
30 words
A semiconductor string connection structure as in claim 1, wherein said transverse plate is of sufficient width to adequately conduct the total electrical current required for all the semiconductor chips.
Claim 6
Dependent Claim
34 words
A semiconductor string connection structure as in claim 1, wherein the transverse plate is folded 180 degrees along a line perpendicular to the conducting leads and midway along the width of said transverse plate.
