Description of the Related Art Conventionally, there has been known a display device in which light-emitting elements such as light-emitting diodes are arranged in a matrix to form a display and various information is displayed in a dot pattern. This type of display device is divided into display blocks each consisting of a display data group to be displayed in series, each display block stores a display period and display data, and when the display period corresponding to the current time is reached, it corresponds to that display block. The display data is sequentially read and displayed on the display.

[0003]

However, if there is display data being displayed at the time when a certain display block reaches the start time, the display of the corresponding display block is completed after the display of the display data being displayed is completed. In order to display the data, it is delayed from the start time of the preset display block,
There was a problem that the display could not be done on time. On the other hand, even if there is display data being displayed when the display period of the display block reaches the start time, it may be excluded from the display target and switched to the display of the corresponding display data.
On the contrary, it becomes necessary to display the display data being displayed to the end. The present invention has been made to address such a problem, and solves the above problem by giving priority or non-priority to display of display data being displayed at the start time of a display block.

In order to solve such problems, the present invention provides a display in which light emitting elements such as light emitting diodes are arranged in a matrix, a driving means for driving the display, Storage means for storing the display period, start mode and display data of the display block consisting of the display data group to be displayed, clock means for measuring the current time, and storage in the storage means based on the current time measured by the clock means. The display data to be displayed in the display period of the displayed display block is given to the driving means, and the display block whose start mode is the natural start ends the display of the display data being displayed when the start time of the display period is reached. The display block for which the start mode is forced to start is forcibly excluded from displaying the display data being displayed when the start time of the display period is reached. It is obtained and a display control unit to be displayed Te.

[0005]

[Operation] Since the display block in which the start mode is set to the natural start is not targeted for display until the display of the display data being displayed is completed at the time when the start time of the display period is reached,
The display data being displayed does not end halfway. Also,
The display block for which the start mode is set to compulsory start is forcibly excluded from the display of the display data being displayed at the time when the start time of the display period is reached, so the display data may be displayed at a fixed time. it can.
