Description

Display device

The present invention relates to a display device, and more particularly to a display device having an odor emission source.

The backlight of the display device can be operated at a temperature of 40 ° C to 80 ° C. In order to prevent the display device from overheating, most of the current technical fields focus on how to provide a good heat dissipation design to ensure the normal operation of the display device. However, if the backlight can be used as a stable heating source and effectively reused, it should be able to reduce the waste of thermal energy and at the same time achieve a heat dissipation effect.

On the other hand, in recent years, Chinese people have gradually paid more attention to and loved aromatherapy, and the aromatherapy of "aromatherapy" through the odor emitting device is quite common. However, conventional odour divergence devices may have the disadvantage of a short odor divergence time, a power hazard or a potential hazard of ignition combustion.

The invention provides a display device having a source of odor emission, which can effectively utilize the heat energy generated by the backlight to cause the odor emission source to scatter the odor for a long time.

A display device of the present invention includes a first housing and a source of odor emission. The first housing has a first body and a fastening structure disposed on the first body, wherein the first body is used to carry and fix the display unit. The odor emission source is removably secured to the fastening structure. When the display unit is turned on, the heat emitted by the display unit is conducted from the first housing to the odor emission source to diverge the odor.

Based on the above, the display device proposed by the present invention has an odor emission source, and when the display unit is turned on, the emitted heat is conducted to the odor emission source to diverge the odor. Therefore, the heat emitted by the display unit can be effectively utilized to achieve energy saving and reduce waste of heat energy, and at the same time, have a heat dissipation effect. On the other hand, by utilizing the heat generated by the display unit, the source of odor emission can scatter the odor for a long time, and the conventional odor emitting device has the disadvantage of having a short odor emission time, a power consumption, or a potential risk of ignition combustion.
