Description

  The present invention relates to a display method for a display device in which a plurality of light emitting elements are arranged on a printed circuit board and a predetermined character, figure, pattern, or the like is displayed by lighting each light emitting element.

  As shown in Patent Document 1, light emitting elements such as LEDs are arranged on a printed circuit board in accordance with letters and numbers, and characters representing business contents and business items, or characters such as “in operation” are displayed in a light-emitting manner. Display devices are known. In this way, a display device that displays specific characters in a fixed manner greatly increases the number of components related to the light emitting elements and their drive circuits compared to a device that can display arbitrary characters by arranging the light emitting elements in a dot matrix. As a result, the display device can be provided at low cost.

On the other hand, the fixed character type display device has the disadvantage that it is inferior in terms of expression ability than the matrix type display device. In the case of a matrix display device, in order to express a character by selectively turning on / off light emitting elements arranged in a vertical / horizontal matrix, the background of the character is lit, or the character portion is turned off. Expressions such as so-called reverse display for lighting the background can be performed. However, in the fixed character type display device, since the light emitting elements are arranged only in the portion representing the character shape, the entire character blinks or the stroke order of the characters as disclosed in Patent Document 1 and Patent Document 2 is used. We are trying to increase the attention with expressions such as lighting on.

  Since the display device of the fixed character system emits only the line segment of the character, there are not many kinds of expressions, and it is important how the attention can be drawn in the display mode limited to some extent become. In one of such display modes, an area for one character represented by arranging light emitting elements on a printed circuit board is divided into a plurality of parts, and the light emitting elements belonging to each of these areas are turned on / off collectively for each area. Some are turned off. One character can be dynamically displayed with the same number of bits as the number of divisions. For example, if one character is divided into three vertically and horizontally, and one character is equally divided into nine squares, the nine squares are an image of a building block. It is possible to display with a movement such as gradually displaying the whole character, displaying the image as rotating from the surrounding square to the central square, or displaying it in an irregular order. Needless to say, display with a high eye-catching effect can be performed with a relatively small number of bits as compared with a matrix display device.

  However, the driving method has a problem that it is difficult to obtain a display effect in the case of characters with a small number of strokes. For example, when “inside” of “in operation” is equally divided into nine squares, squares that do not have any light emitting elements constituting the letters “inside” are in the upper right, upper left, lower right, and lower left. It often appears in the four corners, and if there is a square that does not have a light emitting element, it originally appears as a movement of light by the amount of the square without the light emitting element while having the function of dividing the letters into nine and individually driving to emit light. It does not come. This problem can be solved by reducing the number of cells that divide the character, but considering that it provides light movement that only attracts the viewer's attention, the number of cells is at least one character worth. There is a circumstance that about nine display areas are required by dividing the display area into three vertically and horizontally.

  An object of the present invention is to solve the above-described problems, and is a display method related to a fixed character type display device in which light emitting elements are arranged in accordance with the characters to be displayed or the shape of numerals, and the characters having a small number of strokes It is also an object of the present invention to provide a display method capable of giving a sufficient light movement for attracting attention.

  In order to solve the above problems, the present invention provides a display method for a display device in which light emitting elements are arranged in accordance with dot-represented characters and numerical dots, and the light emitting elements are arranged in a dot shape on a printed circuit board. Thus, a display unit that can display and display a predetermined character and a printed circuit board on which the light emitting element is arranged in the form of a character are divided into a predetermined number of sections within one character area, and the light emitting element The display device is provided with a drive unit that turns on or off, and the display area per character of the printed circuit board is divided into a plurality of areas with different area ratios according to the character shape formed on the printed circuit board to form characters. Proposed is a display method for a display device in which a light emitting element is included in any of a plurality of sections.

  According to the present invention, a display area for one character of a printed circuit board in which a light emitting element is arranged in the form of a light emitting display character is divided into a plurality of areas with different area ratios according to the character shape, and matched to the character shape. The light-emitting elements arranged in such a manner are included in any of the plurality of sections. Therefore, even if a character has a small number of strokes, it is possible to perform the display operation with a high degree of attention by finely dividing the character and making the most of the functions of the display device without wasting it.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  FIG. 1 is an explanatory view showing the appearance of an embodiment of the present invention. Reference numeral 1 denotes a display device main body, which has a display surface 2 on one side or both sides, and the entire device excluding the display surface 2 is surrounded by a waterproof main body casing. On the display surface 2, LEDs are arranged on the printed circuit board so as to match letters and numbers, and in this embodiment, three characters of “management”, “industry”, and “medium” are formed, and the LED is controlled to blink. Thus, each character can be displayed in a flashing manner.

  Next, the overall configuration of an embodiment of the present invention will be described based on the block diagram of FIG. The display surface 2 includes character panels 2-1, 2-2, and 2-3 in which LEDs for one character are arranged on a printed board. The character panel 2-1 has an LED arranged in accordance with each dot of the character “Ying” represented by a set of dots. Similarly, the character panels 2-2 and 2-3 have “industry” “ The LEDs are arranged in accordance with the characters “middle”. Reference numerals 3-1, 3-2, and 3-3 denote LED drive circuits, which blink and drive LEDs arranged on the panels corresponding to the character panels 2-1, 2-2, and 2-3, respectively. 4 is a control unit that outputs LED drive signals to the LED drive circuits 3-1 to 3-3 based on the blink pattern data stored in advance in the ROM 5, and controls the blinking of the LEDs on the character panel. "Middle" characters are lit and displayed in a predetermined manner. The ROM 5 stores a plurality of flashing pattern data, and the pattern switching unit 6 can select desired pattern data.

  Next, the relationship between the LED for one character arranged on the character panel and the section when the LED is driven to emit light will be described with reference to FIG. FIG. 3A shows a state in which the character panel 2-1 is divided into three equal parts in the vertical direction and the horizontal direction, and the character “Ying” is divided into nine sections A-1 to A-9. Nine sections of equal size each include a part of an LED that forms a “Ying” shape, and the LEDs included in the same section are electrically connected in series. The LEDs connected in series in the sections A-1 to A-9 are connected to the LED driving circuit 3-1, and are configured to be turned on or off in units of sections. Further, the LED drive circuit 3-1 can individually drive and drive the sections A-1 to A-9. The nine sections can be turned on / off in a completely random order, or the section of 3 × 3 configuration can be turned on. Turn on / off for each row or column, or rotate in the order of A-1, A-2, A-3, A-6, A-9, A-8, A-7, A-4, A-5 It is possible to display such as turning on / off with an image to be displayed. Of course, the nine sections can be driven at the same timing, and the character “Ying” can be blinked.

  Next, FIG. 3B shows a state in which the “middle” character formed on the character panel 2-3 is divided into nine sections C-1 to C-9. As shown in the figure, in the character “medium”, the dimensions when dividing the vertical direction and the horizontal direction into three are set to different ratios, and the dimensions in the horizontal width direction of C-2, C-5, and C-8 and C-4 , C-5 and C-6 are made smaller in the vertical dimension than other sections. By dividing at such a ratio, the character “middle” is divided by nine sections having different area ratios. Comparing the characters “Ying” and “Middle”, “Ying” is a character shape with a large number of character strokes and line segments that make up the character in the area near the four corners of the character panel. Even if it is divided into three equal parts and divided into sections of the same size (area ratio), LEDs constituting characters are included in all the sections. However, the character “medium” has a small number of character strokes, and line segments constituting the character are regions near the four corners of the character panel (sections A-1, A-3, A-7, A-9 in FIG. 3A). Therefore, when it is divided into nine equal parts as shown in FIG. 3A, a section where no LED exists is generated. Therefore, as shown in FIG. 3B, by appropriately adjusting the ratio when the vertical and horizontal are divided into three according to the character, the area ratio of the sections located at the four corners of the character panel is made larger than the sections at other positions. The line segments constituting the character are included in all nine sections. Similarly to FIG. 3A, the LEDs included in the same section are connected in series and further connected to the LED drive circuit 3-3. With this configuration, when the sections C-1 to C-9 are driven to be lit, the character “medium” can be divided into nine to provide a display effect.

  The present invention is configured as described above, but is not limited to the above-described embodiments, and various implementations are possible within the scope of the claims. For example, in the above-described embodiment, the characters “management”, “business”, and “medium” are fixedly displayed, but it is needless to say that other characters can be used with different numbers of characters. In the above embodiment, the area of one character on the printed board is divided into three sections vertically and horizontally, and is divided into nine sections. However, the number of sections in the vertical and horizontal directions and the ratio of the divided dimensions are adjusted as appropriate to implement the number of sections. You can also.
