Problems solved by technology

However, the above surface area is often limited by the size of the display panel of the backlight module, which affects its heat dissipation efficiency, so that the backlight module will overheat its light source due to poor heat dissipation, which will shorten the service life of the backlight module and reduce its luminous efficiency.

Abstract

The invention discloses a display device with heat dissipating structures and an electronic device using the same. The display device includes a panel, a backlight module, a back cover, a rim frame and a plurality of thermal fins. The backlight module provides the panel with a light source and includes a light emitting unit and a light guide plate. The light emitting unit emits light, and the light guide plate is disposed below the panel for guiding the light emitted by the light emitting unit to the panel. The back cover is installed on an outer side of the panel and the backlight module. The rim frame combines the back cover for covering the panel and the backlight module cooperatively with the back cover. The plurality of thermal fins is disposed on the rim frame for dissipating heat conducted from the rim frame and generated by the light emitting unit.

Description

technical field [0001] The present invention relates to a display device and its electronic device, in particular to a display device with cooling fins and its electronic device. Background technique [0002] Since the liquid crystal itself does not emit light, the backlight module is a key component of the Liquid Crystal Display (LCD) panel. Its main function is to supply a light source with sufficient brightness and uniform distribution so that the LCD panel can display images normally. . As LCD panels have been widely used in many electronic products with growth potential, such as monitors, notebook computers, digital cameras, projectors, etc., the demand for backlight modules and related components is also growing. Generally speaking, the backlight module can be divided into direct-type backlight module whose light source is directly below the display panel and edge-type backlight module whose light source is near the side of the display panel according to the position ...
