Problems solved by technology

[0005] Although the heat generated by the light emitting diode unit 12' is small; but when the backlight source 100' requires a large light intensity and the number of light emitting diode units 12' required by each light emitting diode module 10' is large, due to the light emitting The diode units 12' are arranged on a straight line, and the light emitting diodes in the light emitting diode unit 12' need to be closely arranged to generate white light, so it is easy to make the heat generated by the light emitting diode unit 12' concentrated in a local area and difficult to dissipate, causing the module 10 'local overheating

Abstract

The invention discloses an LED module applied in an LCD device, comprising a substrate and at least one luminescence unit which is formed on the surface of the substrate, wherein, each luminescence unit comprises two first LEDs, a second LED and a third LED, and the four LEDs are connected to form a polygon. The invention also discloses a backlight source. The LED module and the backlight source have the advantages of easy heat dissipation.

Description

technical field [0001] The invention relates to a backlight source for a liquid crystal display device and a light-emitting diode module. Background technique [0002] Liquid crystal display devices are widely used in electronic products such as personal digital assistants, notebook computers, digital cameras, mobile phones, and LCD TVs. However, since the liquid crystal display device is not self-illuminating, it needs a backlight module to produce a display function. [0003] Currently, the light emitting devices in the backlight module are generally cold cathode fluorescent lamps (Cold Cathode Fluorescent Lamp, CCFL) and light emitting diodes (Light Emitting Diode, LED). Among them, a light-emitting diode is a solid-state semiconductor light-emitting device, which uses the combination of two types of carriers (negatively charged electrons and positively charged holes) separated in the diode to generate light. Compared with cold-cathode fluorescent lamps, light-emitting ...
