Led package structures for preventing lateral light leakage and method of manufacturing the same

A method of manufacturing an LED package structure for preventing lateral light leakage, comprising:

• placing a plurality of light-emitting units on a carrier substrate, wherein the light-emitting units are electrically connected to the carrier substrate;
• forming a light-transmitting layer on the carrier substrate for enclosing the light-emitting units;
• cutting the light-transmitting layer to form a plurality of light-transmitting gel bodies, wherein the light-transmitting gel bodies are disposed on the carrier substrate for respectively enclosing the light-emitting units, and the light-transmitting gel bodies are separated from each other to form a gel receiving space among the light-transmitting gel bodies;
• forming a light-shielding gel body to fill up the gel receiving space;
• and
• cutting the carrier substrate and the light-shielding gel body to form the plurality of LED package structures separated from each other, wherein the carrier substrate is cut to form a plurality of circuit substrates for respectively carrying the light-emitting units.

An LED package structure for preventing lateral light leakage, comprising:

• a substrate unit including a circuit substrate;
• a light-emitting unit including at least one LED chip disposed on the circuit substrate and electrically connected to the circuit substrate;
• a light-transmitting unit including a light-transmitting gel body disposed on the circuit substrate for enclosing the at least one LED chip, wherein the light-transmitting gel body has a first light-transmitting portion disposed on the circuit substrate for enclosing the at least one LED chip and at least one second light-transmitting portion projected upwardly from the first light-transmitting portion and corresponding to the at least one LED chip, and the at least one second light-transmitting portion has a light output surface and an outer perimeter surface connected between the light output surface and the first light-transmitting portion;
• and
• a light-shielding unit including a light-shielding gel body disposed on the circuit substrate for exposing the light output surface of the at least one second light-transmitting portion, wherein the first light-transmitting portion and the outer perimeter surface of the at least one second light-transmitting portion are enclosed by the light-shielding gel body, and the light output surface of the at least one second light-transmitting portion is higher than, lower than or substantially flush with the top surface of the light-shielding gel body.
