Description

  The present invention relates to an input data processing method, display system, and program for a display device, and more particularly to an input data processing method, display system, and program for a display device that displays a timetable.

  With the development of information technology and communication technology, the spread of flat displays such as liquid crystal display devices and organic EL display devices has been remarkable. Furthermore, display devices represented by these are applied not only to information / communication equipment but also to various products, and the range of application is further expanding. For example, conventional shelf labels, advertisements, timetables, and the like are displayed by printed materials such as paper and resin plates, and when the display contents are changed, work for exchanging the printed materials manually is performed. For this reason, a lot of resources, time, work and cost are required to change the display contents.

  In view of this, a technique for displaying shelf labels, advertisements, timetables, and the like using a display device capable of changing display contents has been proposed (see, for example, Patent Document 1). This makes it possible to change the display content quickly and easily. The display device proposed in Patent Document 1 includes a memory-type display element that does not require power to maintain display, a photovoltaic power generator that converts light energy into electrical energy, and power generated by the photovoltaic power generator. A power storage device that stores the power, and a control unit that supplies power from the power storage device to the liquid crystal display element and changes a display on the display element.

  It is disclosed that a memory-type display element is configured by using a cholesteric liquid crystal. The cholesteric liquid crystal can change state from the planar state to the focal conic state, and conversely from the focal conic state to the planar state, and both states can be maintained without supplying power. The wavelength of the corresponding color is selectively reflected in the planar state and adjusted to transmit or scatter visible light in the focal conic state.

  The liquid crystal display device further includes an information receiver that receives information from the outside, thereby updating the display according to an instruction from the outside. Display data is wirelessly transmitted to a liquid crystal display device from a communication terminal such as a host computer. The liquid crystal display device receives display data transmitted from the communication terminal by the receiver, and displays (or rewrites) the data on the liquid crystal display element based on the received data. The receiving circuit outputs the received display data to the data conversion circuit. The data conversion circuit converts display data into data and supplies it to the image memory. Display data supplied from the image memory is supplied to the control circuit.

  The control circuit creates display data for one line based on the converted data, and outputs a signal to the decoder and line buffer based on the display data. The decoder drives a necessary switching circuit in response to the received signal and applies a predetermined voltage to the target scan electrode. On the other hand, the line buffer drives a necessary digital-analog converter corresponding to the received signal, and applies a predetermined voltage to a target signal electrode via the drive buffer.

  In this manner, the liquid crystal portions of the three color display layers corresponding to each pixel are switched from the planar state to the focal conic state, or from the focal conic state to the planar state, and a target color image is displayed. Patent Document 2 discloses a technique for turning off or turning on an operation indicator for displaying the end of operation at a stop by installing a transmitter in a vehicle that is finally driven, such as a final bus or a final train.

The following description is to describe the embodiment of the present invention, and the present invention is not limited to the following embodiment. For clarity of explanation, the following description and drawings are omitted and simplified as appropriate. Moreover, those skilled in the art can easily change, add, and convert each element of the following embodiments within the scope of the present invention.

  FIG. 1 shows an example of a basic configuration of an information display system 100 according to the present embodiment. The information display system 100 includes a display device 110 and a control device 120 that controls the display device. The display device 110 includes one or a plurality of display areas. In FIG. 1, as an example, the display device 110 displays a railroad first and last departure time table in two display areas. The display device 110 is installed on the wall surface of a stairway entrance of a railway subway, and can present information such as the start / end time corresponding to the route and the destination to the user. Since the display device 110 can easily change the display contents electrically, the display device 110 can efficiently cope with the change of the first departure time as compared with the timetable printed on the plastic board.

  By transmitting display data corresponding to the display content from the control device 120 to the display device 110, the display content of the display device 110 can be changed. Preferably, the control device 120 and the display device 110 include a wireless communication unit, and the display device 110 is controlled by the control device 120 by wireless communication using Bluetooth (registered commercial). By controlling the display content of the display device 110 using wireless communication, it is possible to cope with various installation locations, and to easily change the display content when the display device 110 is installed. Can do. When controlling the display device 110 by wireless communication, it is preferable to implement a security mechanism such as access control by authentication processing in order to prevent an arbitrary device from accessing the display device 110 and changing the display contents. Note that the communication between the display device 110 and the control device 120 may be wired communication such as RS232C, and may use radio waves in bands other than infrared or Bluetooth (registered trademark).

  The display device 110 preferably includes a plurality of memory areas for storing display data. By storing display data in each memory area, the display screen can be maintained and changed efficiently. In particular, by providing a plurality of memory areas corresponding to each display area, a plurality of display screens can be selectively displayed. As a power supply means of the display device 110, a secondary battery is preferably incorporated. Alternatively, it is preferable to use a solar cell in combination. It is preferable to be able to operate without being connected by wiring from the outside and receiving power supply. Increased system operational benefits.

  The display device 110 preferably uses a memory type display panel. A memory-type display panel is a display having a property that display information can be held without being driven continuously or in a state where the drive voltage is substantially 0V. Examples of the memory type display panel include a cholesteric or chiral nematic liquid crystal display element or an antiferroelectric liquid crystal display element. In particular, it is preferable to use a chiral nematic liquid crystal display element capable of reducing power consumption. The chiral nematic liquid crystal display element has a phase transition type operation. The phase transition type is stable in at least two states of a planar state that selectively reflects a part of incident light and a focal conic state that scatters incident light. A liquid crystal is made to be planar by applying a predetermined voltage between electrodes. It can be transferred to a state or a focal conic state.

  FIG. 2 schematically shows an example of a cross-sectional structure of a two-layered chiral nematic liquid crystal display panel 200 using a chiral nematic liquid crystal display element. The chiral nematic liquid crystal panel has a phase transition type operation and is stable in at least two phases of a planar state in which a part of incident light is selectively reflected and a focal conic state in which incident light is scattered. By applying a predetermined voltage between the electrodes, the liquid crystal can be transferred to the planar state or the focal conic state. The chiral nematic liquid crystal display panel 200 can perform multi-color display by stacking a plurality of cells and selectively reflecting different colors in each cell.

  As shown in FIG. 2, two chiral nematic liquid crystal display cells 232 and 233 having basically the same cell structure are stacked. The first substrate 234 and the second substrate 236 are arranged so that the electrode surfaces of the row electrode 235 formed on the first substrate 234 and the column electrodes 237 formed on the second substrate 236 are orthogonal to each other. The first substrate 234 and the second substrate 236 are fixed to the peripheral sealing material by 238, and a cell space is formed between the two substrates. A chiral nematic liquid crystal layer 239 is sealed inside the cell space. The chiral nematic liquid crystal display panel 200 is preferably driven by a simple matrix method.

  A colored layer 240 made of black matte paint is formed on the back side of the first substrate of the second cell. An adhesive layer 241 is formed between the first cell 232 and the second cell 233. At this time, the two cells are arranged and bonded so that the respective pixels spatially coincide. The chiral nematic liquid crystal layer 239 is driven by a voltage applied between the row electrode 235 and the column electrode 237 arranged to face each other, and the transition of the phase state is controlled to perform display. Since the chiral nematic liquid crystal display panel 200 does not use a polarizing plate, efficient display can be performed. The selective reflection characteristics of the first cell 232 and the second cell 233 are changed to perform different color development, so that a plurality of colors can be displayed. Typically, the dominant wavelength of selective reflection can be adjusted by adjusting the ratio between the chiral agent and the liquid crystal material. The color of the colored layer 240 can be set to other than black, and can be set as appropriate in combination with the selective reflection color of the chiral nematic liquid crystal display element. For example, two-color display of “white-blue” can be displayed by combining selective reflection of orange and a blue coloring layer. The number of layers of the chiral nematic liquid crystal display element may be a single layer, or a three-layer structure can be used for full color display.

  The chiral nematic liquid crystal display panel 200 exhibits a memory property, and when the voltage is set to a predetermined display state by applying a voltage to the column electrode 237 of the second substrate 236, the display state in the state where the applied voltage is set to 0V. Is maintained. By applying a predetermined signal voltage again, the maintained display state can be transferred to another display state. Typically, the color of selective reflection is displayed by setting the entire display surface to the planar state, and the surface of the colored layer 240 (black paint) on the back side is changed to the faintly scattered state by setting the focal conic state. indicate.

  The control device 120 can be configured by a hardware configuration, or by hardware and software executed on the hardware. In this embodiment, an example in which a software program is executed on a general-purpose computer is shown. FIG. 3 shows an example of the hardware configuration of the control device 120. The control device 120 can use a typical computer system, and includes a central processing unit (CPU) 301 and a memory 304.

  The CPU 301 and the memory 304 are connected to a hard disk device 313 as an auxiliary storage device via a bus. Storage medium drive devices such as the flexible disk device 320, the hard disk device 313, and the CD-ROM drive 326 are connected to the bus via various controllers such as a flexible disk controller 319 and an IDE controller 325. A portable storage medium such as a flexible disk is inserted into a storage medium driving device such as the flexible disk device 320.

  The storage medium can store a computer program for giving a command to the CPU 301 or the like in cooperation with the operating system and for executing the function of the control device 120 of the present embodiment. The computer program is executed by being loaded into the memory 304. The computer program can be compressed or divided into a plurality of pieces and stored in a storage medium. The hardware configuration typically comprises user interface hardware.

  The user interface hardware includes, for example, a display device 311 such as a pointing device (mouse 307, joystick, etc.) and a keyboard 306 for inputting, or a liquid crystal display for presenting visual data to the user. . The control device 120 can communicate with the display device 110 via the wireless communication adapter 318. In addition, the said structure can be abbreviate | omitted as needed.

  FIG. 4 is a block diagram illustrating an example of a logical configuration of the information display system 100. Each block is configured by hardware or software executed on the hardware. As shown in FIG. 4, the control device 120 includes an input unit 401 that functions as an interface for data input by a user, and a display unit 402 that performs processing for displaying a display screen on the display device 311 of the control device 120. ing. Further, reference numeral 403 denotes an external storage device, which stores image data of a preset portion on a display screen displayed on the display device 110. A communication unit 404 transmits display data and commands to the display device 110.

  Reference numeral 405 denotes an image data generating unit that generates necessary image data from image data stored in advance in the external storage device 403 and data input by the user via the input unit 401. Each functional block of the control device 120 can be configured by deploying a software program on the memory 304, the CPU 301 performing processing according to the software program, and cooperating with other hardware configurations.

  The display device 110 includes a communication unit 406 for communicating with the control device 120, a plurality of memory areas 407 corresponding to the display areas, a display panel 408 for displaying an image, and a control unit 409 for controlling the operation of the display device 110. It has. The image data transmitted from the control device 120 is received by the communication unit 406 and stored in the memory area 407 by the control unit 409. The display panel 408 displays an image according to the image data stored in the memory area 407.

  In order to display desired image data on the display device 110, the image data generation unit 405 generates bitmap image data in accordance with the display area size of the display device 110. Bitmap image data is generated from image data stored in advance in a storage device 403 such as a hard disk and data input by the user via the input unit 401. Next, the bitmap image data is converted into image data that can be displayed on a chiral nematic liquid crystal display element. The image data conversion process will be described below.

  Multi-color display can be performed by stacking chiral nematic liquid crystal display cells reflecting different colors as shown in FIG. For example, two chiral nematic liquid crystal display cells are stacked, and each cell displays a complementary color relationship of blue and yellow. Further, a black colored layer is provided on the back side of the back side substrate of the panel. As a specific method, an arbitrary threshold value is set for each of RGB colors (R, G, and B each of 8 bits), and the set threshold value is compared with the intensity of RGB. As a result, each RGB colorant is changed from 8 bits to 1 bit, and the RGB expression colors are changed to 8 colors (black, blue, green, cyan, red, magenta, yellow, white). The display data conversion process is disclosed in, for example, Japanese Patent Application No. 2002-119041, which includes the present applicant as the applicant.

  For example, if the expression color is gray (R, G, B) = (128, 128, 128) in a bitmap original image of 24 bits and 256 gradations, if the threshold is set to less than 127, gray is converted to white, and the threshold If is set to 128 or more, gray is converted to black. The expression color by RGB is limited, and attributes corresponding to four colors (black, blue, yellow, white) are added. Thereby, the expression color by RGB is changed from 8 colors. The color is converted into four colors that can be displayed on a chiral nematic liquid crystal display element.

  The above-described panel configuration is changed from four colors (green, cyan, red, magenta) of the image data composed of eight colors to “green to yellow”, “cyan to white”, “red to orange”, and “magenta to blue”. To display color. Then, the image data converted for the chiral nematic liquid crystal display panel display is transmitted to the display device 110 by the communication unit 404. The transmitted image data is stored in one of the memory areas 407 via the communication unit 406 of the display device 110. For example, image data is stored in a specific memory area by designating a memory area from the control device 120, and the image data stored in the specific memory area 407 is displayed on the display panel 408 of the display device 110. Can be made.

  FIGS. 5 to 9 show an example of a user interface displayed on the control device 120 in order for the user to input / edit a display image displayed on the display device 110. FIG. 10 is a flowchart regarding data input processing for generating a display image. In this example, a data input process for generating the image data of the first to last timetable shown in FIG. 1 will be described. In particular, in the following, description will be given by taking, as an example, input processing of image data displayed in the lower display area shown in FIG.

  FIG. 10 shows a flowchart of the process (S101-S106). FIG. 5 shows an example of an initial screen for data input. When a predetermined application program is activated in the control device 120, the display unit 401 acquires data stored in the storage device 403 and displays an input / edit screen. When the “open” icon is clicked, the image data selected from the file stored in advance in the storage device 403 is displayed in the display frames of “original image” and “converted image” as shown in FIG. (S101). The converted image is automatically generated from the image data of the original image. The image data is preferably stored in advance in the storage device 403 as a bitmap image. An original image file stored in advance is designated and displayed as an original image as shown in FIG. At the same time, data for the converted image is generated and displayed in the converted image display frame. Here, the bitmap format data is data representing an image as an enumeration of colored dots. As a bitmap image format, PNG, JPEG, GIF, BMP, TIFF, or the like can be used.

  In this example, specifically, as shown in FIG. 6, according to the image data stored in the storage device 403 in advance, the item names of the first departure time table are displayed on each of the original image display frame and the converted image display frame. Is done. As the item name, “Destination (D)”, “Weekday (W)”, “Sat / Holiday (H)” and the like are shown. A predetermined layout is stored in advance as image data. By storing a part of the image data in advance, the input process for generating the display image can be simplified.

  In the original image display frame, an image based on a bitmap image stored in the storage device 403 and generated by the image data generation unit 405 according to a user input is displayed. In the converted image display frame, an image corresponding to an image actually displayed on the display device 110 is displayed. As described above, the image data generation unit 405 converts the original image data in the bitmap format, and generates image data to be displayed on the chiral nematic liquid crystal display panel. In the converted image display frame, an image corresponding to the actual display image is displayed according to the image data.

  When the chiral nematic liquid crystal display panel performs multicolor display composed of a specific color, the original image and the actual display image are different. For example, when two chiral nematic liquid crystal display cells that selectively reflect blue and yellow complementary colors as in the above configuration are used, the “Saturday / Holiday (H)” of the original image is displayed in red. In an example, “Saturday / Holiday (H)” of the converted image is set to be displayed in a color other than red, for example, yellow. Therefore, it is particularly useful that the user can confirm the actual display image by the converted image display frame.

  Next, as shown in FIG. 7, item text data displayed in each item of the first departure timetable is input via the input unit 401 (S102). Specifically, the text data of the first train destination, weekday first departure time, holiday first departure time, last train destination, weekday last departure time, and holiday last departure time are input in each of the plurality of input boxes. “Destination” includes both Japanese and English notations. If necessary, each item is displayed for each of one or a plurality of first and last trains.

  In this embodiment, each character can be directly input into each input box using a text input device such as a keyboard. Preferably, in an input box for specifying a destination by Japanese notation, a station name (destination) registered in advance by a pull-down menu is selected. The station name displayed in the pull-down menu can be registered in advance corresponding to the station where the display panel is installed (for example, the north station in FIG. 1). The pull-down menu displayed is changed in response to the installation station being selected in the data input process. The pull-down menu can be operated with an input device such as a mouse or a keyboard. The data in the destination English notation box is preferably automatically determined in response to the determination of the destination box in Japanese notation. With such a configuration, it is possible to simplify input processing and effectively prevent erroneous data from being input.

  When the text data input processing is completed, conversion processing of input data into a bitmap image is performed by the image data generation unit 405 (S103). The conversion process to the bitmap image is started in response to the selection of the bitmap conversion button as shown in FIG. The image data generation unit 405 generates bitmap format image data based on the input text data and the image data stored in the storage device 403 in advance.

  Further, the image data generation unit 405 generates image data for displaying an image on the chiral nematic liquid crystal display panel from the bitmap image (S104). Preferably, the bitmap conversion button is set to be selectable after all necessary text data is input. Thereby, an erroneous input by the user can be prevented. In addition, it is preferable that each column for data input or command input is configured to be operable after necessary preprocessing is completed.

  When the original image data and the converted image data are generated, the display unit 402 displays an image corresponding to each of the original image data and the converted image data in each of the original image display frame and the converted image display frame (S105). . FIG. 9 shows an example in which the generated image is displayed in each of the original image display frame and the converted image display frame. In each display frame, for each item, an item name previously stored as image data in the storage device 403 and an item content input as text data and converted into image data in a bitmap format are displayed. When a chiral nematic liquid crystal display panel that performs multi-color display is used, the display colors in the original image display frame and the converted image display frame can be different as described above.

  Finally, when the “Flash Write” command button is selected, image data for the chiral nematic liquid crystal display panel is transmitted to the display device 110 by the communication unit 406 (S106). Image data can be stored in a desired memory area 407 of the display device 110 by selecting a memory number in a box arranged beside the “Flash writing” command button.

  As other commands, the control device 120 erases the image data in the specific memory area by “flash erase”, erases the display image by “panel erase”, displays the image data in the specific memory area by “panel display”, and The storage of the image data in the specific memory area by “Flash writing / panel display” and the panel display of the image data can be transmitted to the display device 110. The display device 110 can execute processing in response to each command under the control of the control unit 409.

  It is preferable that the display device 110 can transmit image data of an image currently displayed on the display device 110 or image data stored in the memory to the control device 120. In response to a command from the control device 120, the control unit 409 of the display device 110 performs an image from a memory area in which image data of a displayed image is stored or from a memory area specified by the control device 120. Data is acquired and image data is transmitted to the control device 120 via the communication unit 407. As a result, the display content can be confirmed remotely, and the display device can be efficiently controlled.

  In this embodiment, an example is described in which one display device 110 is controlled by the control device 120 by wireless communication. For example, a plurality of display devices are connected via a network, and an address is assigned to each display device. Thus, it is possible to construct a system that centrally controls each display device by a central control device. This makes it possible to efficiently control a plurality of display devices installed at various places. By associating the display images of the respective display devices, more efficient control can be performed.

  The timetable display system of this embodiment can change the display contents according to the situation. For example, when there is a change in train operation due to weather conditions, the destination and time can be easily changed. When the image to be changed is determined in advance, the display image can be changed efficiently by displaying the image data stored in advance in the memory area of the display device 110. Note that by using the image data stored in the memory area, it is possible to change the display image periodically by timer control and to change the display contents according to the time. For example, advertisements can be displayed periodically, operation changes for construction, and other display changes that alert the user can be preset and displayed semi-automatically.

  The present invention can be applied to a normal timetable installed for each station or other transportation, in addition to the timetable for the first departure. In addition, temporary information such as operation status can be temporarily displayed instead of the timetable. Further, the control device 120 that can display not only one transportation system but also important information on the system connection and operation state of the entire transportation network is provided with an input screen having a text input field for inputting temporary information. Can be displayed. The temporary information input as text data is converted into image data according to the data conversion process described above, and transmitted to the display device 110. For the display image for the temporary information, the control device 120 can store layout image data in advance. For example, the display device 110 includes a memory area dedicated to temporary information, and can display image data in the temporary information memory in response to a command from the control device 120. Temporary information that is frequently used can be stored in advance in the memory area 407 of the display device 110, thereby enabling efficient display of the temporary information. In the present invention, when the display data of the timetable is changed, management and control at each point for each station can be performed. In addition, it can be controlled and managed in an integrated manner via a network from a central control room that controls the entire transportation network or in units of blocks.
