Abstract

A light emitting diode package according to an embodiment of the present invention includes a plurality of red LEDs, green LEDs and blue LEDs arranged for emitting a white light using a color mixing, at least one white LED emitting the white light and a printed circuit board having a circuit pattern for driving the plurality of red LEDs, green LEDs, blue LEDs, and white LEDs.

Description

technical field [0001] The invention relates to a light emitting diode package and a driving method thereof. Background technique [0002] According to the recent trend of miniaturization and weight reduction of various electric appliances, liquid crystal display devices have become the center of attention. Therefore, liquid crystal panels used as display screens have also been developed among thin liquid crystal panels. [0003] This liquid crystal panel is widely used as a display device for mobile terminals, spaceships, airplanes, and notebook computers. A liquid crystal display device includes an auxiliary light source for emitting light to a liquid crystal panel. [0004] A cold cathode fluorescent lamp (CCFL) is generally used as a light source of the related art. However, recently, light emitting diodes (hereinafter simply referred to as "LEDs") having characteristics of low power consumption, high power, quick response, and environmental friendliness are widely us...
