Abstract

There is provided a method of manufacturing a light emitting diode (LED) package, including discharging a predetermined discharge amount of a phosphor-containing fluid resin to at least one LED package, and measuring color coordinates of white light emitted from the at least one LED package. The method also includes adjusting a discharge amount of the phosphor-containing fluid resin, based on a deviation between the measured color coordinates and target color coordinates, so as to obtain the target color coordinates. The method further includes discharging the adjusted discharge amount of the phosphor-containing fluid resin to another LED package; and curing the phosphor-containing fluid resin dispensed to the another LED package.

Description

[0001] Cross references to related applications [0002] This application claims the priority of Korean Patent Application No. 10-2012-0001979 filed with the Korean Intellectual Property Office on January 6, 2012, the disclosure of which is incorporated herein by reference. Technical field [0003] The inventive idea relates to a method of manufacturing a light emitting device. The method uses a phosphor-containing liquid resin dispensing equipment to manufacture a light emitting device including a wavelength conversion unit. Background technique [0004] A light emitting diode (hereinafter referred to as “LED”) is a semiconductor device that converts electrical energy into light energy and includes a compound semiconductor that emits light of a specific wavelength according to an energy band gap. LEDs have been widely used in backlight units (BLU) of display devices such as optical communication displays or mobile display devices, computer monitors, etc., in backlight units of liq...
