Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an LED display device that displays characters and arbitrary images.
[0002]
[Prior art]
In general, in an LED display device, when displaying characters and images, the displayed contents are blinked, various movements and screens are switched, so that passersby pay attention to the display contents. .
[0003]
In addition to the main display unit for displaying characters and images, LEDs are arranged around the main display unit and in the corners as a sub display unit for decorating the main display unit, and the sub display unit blinks in various patterns. Thus, it has been proposed to pay attention to the display content of the main display unit.
[0004]
In addition, the display device is equipped with a sensor, for example, a sensor that senses the human body, and controls the display so that it is not displayed when there is no passerby, and displays characters and images only when the passerby is detected by the sensor. It is also known to switch.
[0005]
[Problems to be solved by the invention]
However, as a display pattern of the sub display unit that decorates the main display unit, a favorite display pattern selected by the user of the display device from a plurality of display patterns prepared in advance, or display contents of the main display unit A display pattern that changes in software in synchronization with the change is adopted. Therefore, in the display pattern of the sub display unit arbitrarily selected by the user from the display patterns prepared in advance, the display pattern is always repeated, and the sub display unit is synchronized with the display content of the main display unit. In the case of switching the display pattern of the display unit, the display pattern is repeated at a constant cycle. As a result, several types of patterns are repeated for the display pattern of the sub display unit. For this reason, in the long term, a passerby always sees the same display pattern of the sub-display unit, so that the decoration effect of the main display unit decreases as the display period becomes longer.
[0006]
On the other hand, when a sensor is provided and the display contents are switched according to the sensor detection status, the same display pattern continues in places where there are many passers-by, or when characters are scrolled and displayed, In response to the sensor, the display content is switched to another display content.
[0007]
The present invention has been made in view of such problems, and an LED display that can change only the display pattern of the sub-display unit that decorates the main display unit that displays characters and images according to the detection signal of the sensor. A device is provided.
[0008]
