Description

  The present invention relates to a digital signage for store advertisement that is installed in a store and displays advertisement information of the store.

  A store signage digital signage that is installed in a store and displays advertisement information of the store is known. The mainstream of digital signage for store advertising is LED display type digital signage in which a large number of LEDs (light-emitting diodes) are arranged in a matrix and images (characters, still images, moving images, etc.) are emitted and displayed based on the light emission control. However, in recent years, high-resolution panel display type digital signage that displays a clear image based on display control of a high-resolution display panel including a liquid crystal display, a plasma display, and the like is also increasing (for example, see Patent Document 1). ).

JP 2010-282109 A

  The LED display type digital signage has a disadvantage that the resolution of the image is inevitably reduced because a large number of LEDs are arranged in a matrix and an image is displayed based on the light emission control. Since it emits light by itself, it has an advantage that it can display an image with high luminance (5000 mcd to 10,000 mcd or more) comparable to direct sunlight and has high heat resistance.

  On the other hand, high-resolution display panels such as liquid crystal displays and plasma displays have the advantage of being able to display clear high-resolution images, but because the luminance is as low as about one-tenth that of LED displays (about 500 mcd to 1500 mcd). In order to use it outdoors, it must be operated away from direct sunlight, and because of its low heat resistance, it causes a blackening phenomenon (blackout) as the temperature rises, making the display screen invisible It has the disadvantages.

  In addition, high-resolution display panels such as liquid crystal displays and plasma displays have a relatively high heat resistance when the screen size is as small as 15 to 19 inches, and can withstand outdoor use, but 32 and 46 inches. When the size is too large, the heat resistance performance is extremely lowered, and there is a problem that use restrictions such as indoor use avoiding direct sunlight, semi-outdoor use, shade use, eaves use, and shade use are forced.

  In recent years, as an outdoor type liquid crystal display or plasma display of about 32 inches or more, as a measure for suppressing the temperature rise in the display device, a model equipped with an air conditioner in the display device is also known, but the price is high. In addition, it has the disadvantages that the weight of the product becomes heavy and it is extremely difficult to put in and out the display device.

  Moreover, in order to lower the temperature in the display device, a model equipped with a forced ventilation device (fan or the like) is also known, but depending on the installation location, the temperature in the display device in the summer can be 50 degrees to 60 degrees. Therefore, in an outdoor type liquid crystal display or plasma display having a size of about 32 inches or more, a phenomenon in which a blackening phenomenon occurs due to a temperature rise in the display device and the display screen becomes invisible actually occurs. When the blackening phenomenon is repeated, there is a problem that the display panel itself deteriorates and the product life is shortened.

The present invention was created for the purpose of solving these problems in view of the above circumstances, and is a store signage digital signage that is installed in a store and displays advertisement information of the store, At least two display surfaces that are arranged in a back-to-back manner, each displaying a store advertisement information in a different direction, are integrally provided, and one display surface has a plurality of LEDs arranged in a matrix, A high-resolution panel display unit configured to display an image based on display control of a high-resolution display panel formed of a liquid crystal display, a plasma display, or the like, which includes an LED display unit that displays an image based on light emission control. It is characterized by comprising.
The display screen may further include display direction changing means for manually or automatically changing the display direction of the display surface.
Further, the irradiation direction determination means for determining the irradiation direction of sunlight, and one of the display surfaces composed of the LED display unit is exposed to sunlight, and the other display surface composed of the high resolution panel display unit is not irradiated with sunlight. And a display direction automatic control means for automatically changing the display direction of the display surface.
In addition, a heat insulating material that blocks conduction of heat to the high-resolution panel display unit is disposed between the LED display unit and the high-resolution panel display unit.
The display device further includes display / sound synchronization control means for synchronizing the display image of the LED display unit, the display image of the high-resolution panel display unit, and the sound generated by the sound generation unit.

According to the first aspect of the present invention, one of the two display surfaces arranged back to back is constituted by the LED display unit, and the other display surface is constituted by the high resolution panel display unit. The disadvantages of the display unit and the high-resolution panel display unit are complemented to each other, and the operation suitable for the location conditions of the store becomes possible. For example, in a store with a location condition where a strong western sun is inserted, the LED display unit is directed in the direction in which the western sun is inserted, and a digital signage for store advertisement is installed so that the high resolution panel display unit does not receive the sun. In this way, on one display surface, the LED display unit with high heat resistance and high brightness performs light-emitting display that is not defeated by the sun, while the other display surface is clear by the high-resolution panel display unit. High-resolution display can be performed, and as a result, not only effective advertising display can be performed, but also the temperature increase of the high-resolution panel display unit inferior in heat resistance can be suppressed.
According to the invention of claim 2, since the display direction changing means for changing the display direction of the display surface manually or automatically is provided, the display direction of the display surface can be arbitrarily set according to the change of the irradiation direction of sunlight, etc. Can be changed.
According to the invention of claim 3, the irradiation direction determination means for determining the irradiation direction of sunlight and the other display including the high resolution panel display unit when the sunlight hits one display surface including the LED display unit. Display direction automatic control means for automatically changing the display direction of the display surface so that sunlight does not hit the surface, so that the display direction of the display surface is changed according to changes in the sunlight irradiation direction, etc. Save time and effort.
According to the invention of claim 4, since the heat insulating material that blocks conduction of heat to the high resolution panel display unit is disposed between the LED display unit and the high resolution panel display unit, the heat resistance is poor. It is possible to suppress the temperature rise of the high-resolution panel display unit and to make the display surface less likely to be blackened.
According to the invention of claim 5, since the display / sound synchronization control means for synchronizing the display image of the LED display unit, the display image of the high resolution panel display unit, and the sound generated by the sound generation unit is provided, It is possible to conduct useful and effective advertising activities for stores introducing digital signage for store promotions such as hourly promotion, day-of-week promotion, annual event promotion, etc. by integrated operation that links the three display surfaces and audio It becomes.
