Display device

The present invention relates to a display device, and more particularly to a display device capable of emitting an aroma.

In recent years, display devices have become increasingly popular. For example, digital photo frames, liquid crystal screens, and notebook computers have all utilized display devices, and they have flourished, and there are various designs on the display devices.

However, modern people are busy with work and work pressures, and they need to relax to relieve stress. It is known that a fragrance is added to a plastic material in a casing of an electronic device, and the aroma is emitted as an outer casing of the electronic device. However, in the case of such a device, when the fragrance is finally discharged, it cannot be replenished. And its spices are not guaranteed to be natural. TWI255683 discloses a portable electronic device and a battery module thereof, which is provided with an odor unit in an electronic device accommodating space covered by the casing, and specially constructed a heat source (for example, a thermocouple metal) adjacent to the scent The unit provides a heat by flowing a current through the heat source to cause the odor unit to receive heat and emit an odor. The odor unit is, for example, an absorbing material for adsorbing odorous substances, but because it is disposed inside the accommodating space covered by the casing, it is inconvenient to replace in the replacement, and the adsorbent plate is not allowed to adsorb too much essential oil liquid to avoid liquid. Drip. The existing digital photo frame (DPF) has no fragrance.

Therefore, there is still a need for a novel display device that can ensure the natural aroma to be dispensed, and that the supplement or replacement of the essential oil is convenient without damaging the inside of the device.

An object of the present invention is to provide a display device in which a back cover accommodates a fragrance box, and the user can select an essential oil to supplement or replace the fragrance box by using a unique box and lid design. Furthermore, it can be heated by the existing heat source in the display device to disperse the aroma and create an atmosphere of pleasant environment.

A display device according to the present invention includes a display panel, a printed circuit board including a wafer processor located behind the display panel, a front frame located in front of the display panel and having an opening to expose the display panel, a back cover, and a fragrance box . The back cover covers the display panel and the printed circuit board to be combined with the front frame, and has a receiving recess on the back cover. The fragrance box is placed in the receiving recess. The scented box includes a case having an opening and a cover which is engaged with the case by an elastic mechanism in the case.

The display device according to the present invention is provided with a groove on the back cover of the display device for placing a fragrance box, and by opening the lid of the essence box, the essential oil can be conveniently added, or the essence box can be replaced to replace the essential oil. In particular, it is convenient for the user to use the favorite essential oils, such as natural essential oils. Furthermore, the groove position can still correspond to the crystal of the printed circuit board. The position of the light source of the chip processor or backlight module to utilize the heat generated by the wafer processor or light source to help dissipate the aroma without additional heat or additional power.

The display device according to the present invention may be, for example, a digital photo frame, a television, a monitor, or a notebook computer. The display device may include a display panel and a printed circuit board. A front frame is located in front of the display panel and has an opening. The display panel is exposed, and the display panel and the printed circuit board are covered by a back cover, and combined with the front frame. The printed circuit board is located behind the display panel and has a wafer processor disposed thereon. The wafer processor can be, for example, a time controlling IC chip (T/C or T-Con) or a size scaling control product. A wafer processor such as a Scalar IC chip. The display panel can include two types of active illumination and non-active illumination. Active light-emitting display panels do not require a backlight module. A non-active display panel requires a backlight module, such as a liquid crystal panel or other panel that requires a light source. The backlight module has a light source and is located between the display panel and the printed circuit board, and the light source thereof can be, for example, a light emitting diode or a cold cathode fluorescent tube. Generally, if it is a direct type backlight module, the light source is located below the backlight module; if it is a side light type backlight module, the light source is located at the side of the backlight module. Therefore, a portion of the light source will directly correspond to the back cover without the presence of a printed circuit board between the light source and the back cover. The wafer processor or light source can generate heat when the display device is in operation. For example, the heat of the wafer processor can sometimes be as high as 60 to 70 °C. In the present invention, the back cover is further provided with a concave shape at a position corresponding to the wafer processor or a back surface of the backlight module (if the display device has a backlight module) corresponding to the light source, as an accommodation. Groove, The receiving recess is preferably recessed by the back cover toward the front of the display device. The shape of the receiving groove is formed at the same time when the back cover is formed, but the bottom of the groove is preferably a heat conductive material (for example, a metal sheet) to promote absorption of heat. Providing a fragrance box in the receiving recess, the fragrance box comprises a box body having an opening and a box cover, so that the lid is exposed to the external environment (ie, the user's environment), so that the user can self-display the device Move the lid externally, for example, press the lid into the box to expose the opening for the addition of essential oils. Because the receiving groove can correspond to the position of the wafer processor or the light source, the heat generated by the wafer processor or the light source during the operation of the display device can be absorbed to heat the essential oil in the box to achieve the purpose of releasing the aroma. The present invention utilizes such a heat source without the need for additional power.

The case and the lid may be, for example, a plastic material. A liquid absorbing cotton material may be further placed in the casing to adsorb the essential oil, but it is preferred that the opening of the lid is not affected. The combination of the scented box and the receiving recess can be accomplished in a variety of ways, such as by snap fit, helical engagement, simple mating, or even direct bonding.
