2. Description of the Related Art In a city building area, display devices of various forms are overflowing and are used for various advertisements such as product information, service information or news information. As anyone can realize, a large-screen display device is superior in terms of information advertising effect. A large signboard and lighting are all that is needed to transmit fixed information, but a dot-matrix TV screen type display device that can freely display textual information and moving images is used to convey various changing information. Has been done.

[0003]

A very large dot matrix display device installed on the roof or wall of a building is extremely expensive. In addition to the device itself being expensive, the structure for installing the device and the installation work also require considerable expense. Therefore, the device is not easy to use. In particular, it cannot be used for the purpose of advertising for a limited period of time.

As is well known, since a limited period is required, a banner is used for the purpose of using the outer wall surface of a building to carry out a large-scale advertisement as much as possible while keeping the cost as low as possible. Or curtains are often used. For example, a banner or banner with capital letters such as "Congratulations on Yakult victory" will be installed along the outer wall of the building. This is certainly cheap, but there is a definite problem that the content of information is fixed. In addition, if this kind of banner or banner is installed on the outer surface of a building with many windows, the window will be blocked by a wide curtain cloth, and the comfortability of the room inside the window will be significantly reduced. When the outside light is taken in from the window to create an indoor atmosphere, or when there is a restaurant or the like in the building that offers a view outside the window, the window cannot be closed with the curtain cloth. Furthermore, in the case of hotels and museums that sell the beauty of the exterior of the building, there are resistances to installing dazzling banners and banners on the proud outer wall.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to install nothing on the outer wall surface of a building, to impair the function of the window on the outer surface of the building, (EN) Provided is a method and device for displaying a large screen scrolling from the inside of a building to a person outside through a window, which is capable of displaying a variety of information with high graphic presentation effects and can be performed at a reasonable cost. Especially.

BEST MODE FOR CARRYING OUT THE INVENTION

[Appearance of Embodiment] Since the equipment and facilities of the display system of the present invention are installed inside the window glass of the building, they hardly appear in the appearance of the building, but as shown in FIG. 1 and FIG. 2, for example. Become. The building of this example has an outer surface of a glass having a curtain wall structure, and 32 bar-shaped indicators 2 are vertically arranged inside a window glass 1 on the third floor.

The bar-shaped display 2 has a total length of about 2 meters,
There are 64 light emitting cells (LED collective lamp) on the front.
3 are arranged linearly at a pitch of about 3 cm. Each bar-shaped indicator 2 is vertically placed on the floor of the third floor with an appropriate stand structure and is placed very close to the inner surface of the window glass 1. In addition, 32 bar-shaped indicators 2 are arranged in parallel at approximately constant intervals of about 1 meter. However, it is not necessary to keep this interval strictly constant, and there may be some error depending on the indoor conditions. Furthermore, when the bar-shaped indicators 2 are arranged over the windows of a plurality of rooms partitioned by walls or the like, there is a situation in which the bar-shaped indicators 2 cannot be installed at the above-mentioned intervals due to the walls between the windows. In that case, the bar-shaped display 2 is not arranged at that position, and as a result, there may be a very local gap in the array at regular intervals.

In the system of this embodiment, it is considered to display information to people walking on the sidewalk opposite to the building on the road adjacent to the building. The 64 light emitting cells 3 in each rod-shaped display 2 are arranged with directivity aligned so as to project light in the same direction, and the spread of the directivity is considerably large. Moreover, when 32 bar-shaped indicators 2 are installed side by side inside the window glass 1, the direction of each installation is such that the center of the light emitted from each of the three rows of light emitting cells faces the sidewalk. Adjust.

[Display Control Circuit System] A block diagram of FIG. 3 shows a display control circuit system according to an embodiment of the present invention. As described above, each bar-shaped indicator 2 has 6
A light emitting cell array Ai in which four light emitting cells (LED collective lamps) 3 are linearly arranged at close intervals is provided, and a 64-bit drive circuit DSi for driving the light emitting cell array Ai is incorporated. . Note that i is an integer indicating the arrangement order of the 32 rod-shaped indicators 2, and i = 1, 2, 3, ...,
32.

The drive circuit DSi is a circuit in which a 64-bit shift register 4, a 64-bit latch circuit 5, and a 64-bit driver 6 are integrated together.
The latch circuit 5 holds the 64-bit display data transferred to the display driver 6, and the driver 6 drives the 64 light emitting cells 3 for display according to the 64-bit display data.

Each of the 32 rod-shaped indicators 2 is connected to each other in series by a cable and has a common central control unit 7.
It is connected to the. The 32 64-bit shift registers 4 included in each of the 32 drive circuits DSi are all connected in series to form a (64 × 32) -bit shift register as a whole, and the serial shift registers are centrally controlled. It is connected to the device 7.

The image memory 8 of the central control unit 7 has a vertical 6
The image data is stored in a bitmap format of 4 bits and the size of which is horizontal. 6 in each column of the image data
4-bit data is referred to as column data, and each column data is sequentially numbered as D1, D2, D3, ... (General term is expressed as Dj). The image memory 8 has 1 word = 6
It is assumed that the column data Dj is stored at the address j with a 4-bit structure.

The processor 9 of the central control unit 7 makes a read access to the image memory 8 as follows. The column data Dj read out in parallel from the image memory 8 in 64 bits is serialized via the shift register 10 for parallel / serial conversion, and 32 64-bit shift registers 4 are serialized as described above ( It is input to the 64 × 32) bit shift register. By inputting column data for 32 columns serially from the central controller 7 to this (64 × 32) bit shift register, 64 bit column data was given to each of the 32 64-bit shift registers 4. become. At this time, a latch signal is given from the central controller 7 to each drive circuit DSi, the data in the shift register 4 is transferred to and held in the latch circuit 52, and the 64-bit display data is used to drive the driver 6 to generate 64 light emitting cells 3. To drive. At the same time, the data in each shift register 4 is updated.
The scroll display is performed by repeating the above operation.

[Display Control Procedure] The flowchart of FIG. 4 shows the control procedure of the read access of the image memory 8 by the processor 9 in the central control unit 7. In the first step 601, the start pointer P is set to 0, and in the next step 602, the value of the start pointer P is moved to the address pointer j (j = P = 0 at the stage of this description). Further, the column counter C is set to 0 in step 603.

At the next step 604, the image memory 8 is read-accessed at the address j indicated by the address pointer j, and the read column data Dj is transferred in series as described above. In the next step 605, 10 is added to the address pointer j. Here, "adding 10 to j" instead of adding 1 to the address pointer j is a characteristic of the skip scroll display method of the present invention (the meaning will be described in detail later).

At the next step 606, the column counter C is incremented by 1.
Is added, and it is checked in step 607 whether the value of the column counter C has reached the final value n = 32. C = 3
It returns to step 604 until it becomes 2, and step 605
The image memory 8 is read-accessed according to the address pointer j updated in. When C = 32, the column data is distributed to each of the 32 shift registers 4. In this case, the process proceeds to step 608 to generate a latch signal as described above.

Of course, the column data in the image memory 8 is Dj → D (j + 1) → D (j + 2) → D (j + 3).
→ D (j + 4) → D (j + 5) → D (j + 6) → successively forms image data. In the discrete scroll display method of the present invention, if the column data Dj is transferred to the drive circuit DS32 of the first bar-shaped display device 2 by the above-mentioned data transfer control, it is transferred to the drive circuit DS31 of the bar-shaped display device 2 adjacent to the column data Dj. Is column data D (j + 10)
Is transferred, and the drive circuit D of the adjacent bar-shaped display 2 is further transferred.
The column data D (j + 20) is transferred to S30, and the column data D (j + 30) is similarly transferred to the drive circuit DS29.
The column data D (j + 40) is stored in the drive circuit DS28.
The column data selected every 10 columns, such as ..., is transferred to each bar-shaped display 2.

At the next step 609, 1 is added to the start pointer P to prepare for advancing the image to be displayed by one unit in the scroll direction. In the next step 610, it is checked whether or not the value of the start pointer P has reached the value MAX indicating the end of the image to be displayed. Until P = MAX, the flow returns to step 602 to advance the scrolling of the image. When P = MAX, the flow returns to step 601 to restart the scrolling of the image from the beginning.

[Split-and-scroll display method] The display control in the above embodiment can be expressed as follows. Then, the scroll display having such requirements will be referred to as an interlaced scroll display system.

(A) m = n having 64 light emitting cells 3
= A strip-shaped screen area consisting of (64 × 32) light-emitting cells 3 of 64 dots in length and 32 dots in width is formed along the window glass 1 on the third floor of the building by 32 bar-shaped displays 2. On the other hand, in the image data of the bitmap format stored in the image memory 8, the strip-shaped screen area has m = 64 dots in the vertical direction and w = (n × 11) −1 in the horizontal direction.
It is created considering that it is a screen in which pixels of 0 = 342 dots are arranged.

(A) In the strip-shaped screen area, which is regarded as a screen having a pixel configuration of (64 × 342) dots as described above, the image data of (64 × 342) dots is laterally moved at a certain moment. Is (64 × 32) according to the data of (64 × 32) dots which are selected in every 10 columns.
The light emitting cells 3 are driven.

[How to view the jumping scroll display method] In order to explain how the jumping scroll display method looks to an observer, an example different from the embodiments of FIGS. The relationship between the column Ai and the column data Dj is schematically shown in FIG.

In the example of FIG. 5, the flow of image data in the bitmap format of two characters "Maru", in which one character is composed of 16 × 16 dots, and six light emitting cell rows Ai to A
(I + 5) is overlaid and expressed. A portion where the data dot and the dot of the light emitting cell 3 overlap is shown by a black circle, and the black circle cell 3 emits light. As shown in detail, of the one-character data composed of 16 column data, only the three column data that are randomly selected are displayed in the three light emitting cell columns. The 13 columns of data are not displayed at all. However, for example, by performing scroll display control at a speed of four characters per second, a person observing the scroll recognizes the character as a 16 × 16 bit character.

Similarly, as in the embodiment of FIGS. 1 to 4, even if the installation intervals of the bar-shaped indicators 2 are large (1 meter interval in the specific example), the density of the image data to be scroll-displayed should be sufficiently high. Every other (11 times the density in the specific example), the scroll display control is performed while selecting every 10 columns of skipped column data as in the procedure described above. A recognition effect (afterimage effect) that complements the displayed data sequence occurs, and the image scrolled by the vehicle occupant traveling in the target road range is as intended (according to the dot density of the image data).
You can see it. Of course, in order to obtain the intended visual effect, it is necessary to increase the scroll speed to some extent. FIG. 2 shows a state in which the character string "summer size sale" is scroll-displayed.

[Other Examples of Embodiments] The rod-shaped display device may be in a horizontal posture and a large number may be arranged in the vertical direction at large intervals. That is, each bar-shaped display is installed almost horizontally inside the window glass from the upper floor to the lower floor of a high-rise building.
It is possible to construct a system in which a total of several dozen rod-shaped display devices are arranged in parallel at a distance of 0 to 100 centimeters per floor and scroll display is performed in the vertical direction by the same principle as described above.

In the display control system shown in FIGS. 3 and 4, a moving image can be scroll-displayed by temporally changing the image in the memory 8 by another processing system. 3 and 4, the processor 9 randomly picks up the image data from the memory 8 and transfers it in series to each bar-shaped display 2 for distribution. The present invention is not limited to such a method. For example, by outputting the image data in series without a gap and delaying the data at each bar-shaped display 2, each bar-shaped display 2 picks up each of the scattered column data, the same display output operation is realized. it can.

【The invention's effect】

(1) By installing a large number of the bar-shaped display devices inside the window glass of a building at large intervals, it is possible to easily form a very large band-shaped screen region. Even if the installation interval of the bar-shaped display device is large, the density of image data to be scroll-displayed is set sufficiently high, and scroll display control is performed while selecting the above-mentioned scattered column data. Due to the function of the visual center, a cognitive effect (afterimage effect) that compensates for the gap between the data sequences that are displayed in a scattered manner occurs, and the image that scrolls to people in the street outside the window is scrolled as intended (according to the image data dot density ) You can see it.

(2) Image data including character strings and figures can be easily generated by a personal computer or word processor, and freely created images can be scroll-displayed in the large band-shaped screen area described above. It is possible to easily display various information at very low cost.

(3) Since nothing is installed on the outer surface of the building, the appearance of the building is not impaired at all.

(4) Since the bar-shaped indicators are installed in large intervals at the inside of the window glass, most of the functions of the window are such that the outside light is taken in and that the outside scenery can be seen from the room. The present invention can be carried out easily without damaging the present condition of the interior of a room such as a hotel, restaurant or museum.

(5) Since each bar-shaped indicator is a very small and light piece of equipment, it is a very simple task to install and remove these inside the window, and therefore the display of the present invention can be promptly performed when necessary. The system can be installed in the building and the equipment can be quickly removed when the usage period is over, which is extremely practical and the implementation cost is low. Of course, the equipment can be reused repeatedly. In particular, if each bar-shaped display unit and the central control unit are wirelessly connected to each other, the installation and removal can be further simplified.

(6) Despite displaying a large screen toward the outside of the building, since the equipment (bar-shaped display) for that purpose is installed indoors, it is not necessary to consider waterproofing and corrosion prevention measures. In this respect, it is really economical.
