A display apparatus has a liquid crystal display having a display panel, a housing, a circulating fan, and an air conditioner. The housing has a sealing part. The sealing part seals around the display panel and accommodates the display panel therein, while making the display screen viewable from outside. The circulating fan circulates air along a circulation path surrounding the display panel wherein the path includes a space between the display screen and the sealing part. The air conditioner collects heat from the air circulating the circulation path and releases the heat to outside of the housing.

Display apparatus

A display device of this invention comprises a display panel, an accommodating part accommodating the display panel, circulating means for circulating air in the accommodating part around the display panel, which is arranged on a rear surface side of the display panel, an advertizing part arranged on the rear surface side of the display panel, and an illuminating part illuminating the advertizing part from the display panel side and arranged at a position below or above the circulating means. Another display device comprises a display panel, a fan arranged on a rear surface side of the display panel and forming an air flow on a display screen of the display panel, an advertizing part arranged on the rear surface side of the display panel, and an illuminating part illuminating the advertizing part from the display panel side and arranged at a position below or above the fan.

Display device having an advertizing part

A display apparatus includes a liquid crystal display having a display panel, a housing, and a plurality of heat pipes. The housing has a sealing part and has aeration paths. The sealing part seals the display panel to box the display panel therein, while making a display screen of the display panel viewable from outside. The aeration paths are arranged outside the sealing part and communicate with the outside of the housing. The heat pipes extend from a rear surface of the display panel to the aeration paths.

The outdoor display apparatus has a display unit, a blowing unit which generates air along the display unit, and a channel part which emits the air passed the display unit, wherein the channel part is extended to the lower part of the displaying unit from its side part, and at least a portion of the channel part is laid underground.

Outdoor display apparatus

A display apparatus according to the present invention comprises a display part, a housing which accommodates the display part, a circulator circulating the air in the housing around the display part in a vertical direction, and a fan provided on a rear side of the display part. The housing makes the display part be seen from outside therethrough. The fan converts the flow of the air circulating in the vertical direction to a horizontal direction in order to disperse heat generated from a rear surface of the display part.

A display apparatus has an image display panel accommodated in a housing, a circuit board which controls operation of the image display panel, and an installation plate arranged on a rear side of the image display panel. Here, the circuit board is installed on the installation plate, and the installation plate is rotatable with respect to the housing.

A display apparatus has a first chamber accommodating a display panel, a second chamber accommodating a circuit board which controls the panel, and a heat radiating unit arranged at the rear side of the second chamber.

A display device according to the present invention comprises a housing having a waterproof structure and provided with an accommodation room formed therein, a ventilation part defined outside the accommodation room and leading to outside of the housing, a display panel arranged inside the accommodation room and including a display screen viewable from a front surface side of the housing, and one or a plurality of heat pipes arranged on a rear surface side of the display panel. The heat pipe passes through a side surface wall forming the accommodation room and extends from inside of the accommodation room to inside of the ventilation part.

Display device

A display apparatus includes an accommodation chamber having a sealed structure, a display panel accommodated in the accommodation chamber, a cooling part which cools the air inside the accommodation chamber, a drain pipe extending from a bottom part of the accommodation chamber, and a check valve provided in the drain pipe.

A display apparatus has a display panel, a circuit unit which controls the display panel, a first chamber which accommodates the display panel, a second chamber which arranged behind the first chamber, the second chamber accommodates the circuit unit, a cooling device which cools the display panel, and a ventilating part which ventilates between the first and the second chamber. The air emitted from the cooling device is led to the back side of the display panel via the front side thereof, and then ventilates the ventilating part.

A display device according to the present invention comprises a display panel, an accommodating part accommodating the display panel, circulating means for circulating air in the accommodating part around the display panel, a heat exchanger collecting heat from the air, which is arranged on a rear surface side of the display panel, and a heat insulating member provided between the heat exchanger and the display panel. Another display device according to the present invention comprises a display panel, an accommodating part accommodating the display panel, a fan forming an air flow on a display screen of the display panel, a heat exchanger collecting heat from air, which is arranged on a rear surface side of the display panel, and a heat insulating member provided between the heat exchanger and the display panel.

A display device according to the present invention comprises a display panel, a housing sealing around the display panel and making a display screen of the display panel viewable from outside, and a heat exchanger collecting heat, which is arranged on a rear surface side of the display panel. Another display device according to the present invention comprises a housing having a waterproof structure and provided with an accommodation room formed therein, a display panel arranged in the accommodation room and including a display screen viewable from a front surface side of the housing, a heat exchanger collecting heat generated from the display panel and arranged on a rear surface side of the display panel, and a second heat exchanger releasing heat collected by the heat exchanger to outside of the housing and arranged outside the accommodation room.
