Abstract

An embodiment of the invention discloses a light-emitting diode package which comprises a plurality of red LEDs (light-emitting diodes), green LEDs, blue LEDs, at least one white LED and a printed circuit board. The red LEDs, the green LEDs and the blue LEDs emit white light by mixing colors, the white LEDs emit white light, and the printed circuit board is provided with circuit patterns for driving the red LEDs, the green LEDs, the blue LEDs and the 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 light weight of various electrical appliances, liquid crystal display devices have become the center of attention of A,: frj. 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 w...
