Abstract

A backlight module comprises a support provided with a cavity, a light source arranged on the support, a micro capillary structure formed at the surface of the cavity and a fluid arranged in the cavity.

Description

technical field [0001] The present invention relates to a backlight module, and in particular to a heat dissipation structure of the backlight module. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range, so it has been widely used in portable TVs, mobile phones, video recorders, etc. In consumer electronics or computer products such as video projectors, notebook computers, and desktop displays, displays have become the mainstream. [0003] A liquid crystal display mainly includes components such as a liquid crystal panel, a backlight module, and a frame. The backlight module is used to provide a light source, and mainly includes components such as a light source, a light guide plate, and a bracket. The liquid crystal panel and the backlight module are then assembled in the frame. [0004] The light source is the main heat source in...
