Description

  The present invention relates to a display device and a display system having a calendar display function capable of displaying a schedule for individual or plural persons.

  Conventionally, a calendar is generally displayed on a desk or a wall-mounted date on a monthly basis, and the material is mostly printed on paper or the like. At work and at home, you can share and use a common event schedule or your own schedule at the date. In addition, the calendar has a high value for interior decoration and is widely spread and used.

  On the other hand, in recent years, electronic calendars have been developed that digitize wall-mounted paper calendars, and the date display can be selected and displayed on the display unit as year, month, or day. As for the display, the current date is identified and displayed with a frame. Furthermore, a handwriting input unit is provided so that characters input by handwriting can be displayed as, for example, a monthly memo in the memo area (Patent Document 1).

  Moreover, although it is not a wall calendar, what inputs a schedule related to a date by handwriting to a calendar-type schedule is known as input devices, such as an electronic notebook (patent document 2).

  However, in these electronic calendars, the schedule contents registered by handwriting input are displayed in a memo area unrelated to the calendar date, so it is difficult to understand the relationship between the schedule contents and the calendar date. There was a problem that it was not possible to grasp the schedule.

  Moreover, when the registration of the schedule is only registration by handwriting or switch operation, and the same schedule content such as a meeting or going out is registered for different registration dates, registration by handwriting input or switch operation must be repeated each time. In addition, there is a problem that the input operation takes time and effort.

  As a measure to improve this, a schedule display unit is provided for each date, and the tag ID of the RF tag mounted on the card prepared corresponding to the schedule contents by handwriting input and reader / writer is read as an identifier by non-contact communication and database There is also known an electronic calendar that allows a schedule to be registered easily and easily by acquiring a schedule from Japanese Patent Application Laid-Open No. 2003-312707 (Patent Document 3).

  However, even with this improved electronic calendar, there are problems that a schedule of a plurality of persons cannot be individually managed and a schedule cannot be input from a long distance such as a place where the user is away.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 shows a display system 1 according to an embodiment of the present invention. For example, information input using input terminals 10-1 to 10-M or display devices 80-1 to 80-N is shown. The server device 30 acquires the acquired information and displays the acquired information on the display units of the display devices 80-1 to 80-N.

  The display device of the present invention includes a display unit for displaying information, an input terminal for inputting schedule information, a communication unit for transmitting the input schedule information and receiving the schedule information input at a remote place, and an input The control unit is configured to display the received schedule information and the received schedule information on the display unit. The schedule information can be individually transmitted / received, or the schedule information can be transmitted / received via a server device placed in a center or the like. It is also possible to do.

  Hereinafter, in the input terminals 10-1 to 10-M, the display units 50-1 to 50-N, and the display devices 80-1 to 80-N, unless otherwise distinguished, “-(hyphen)” added after the reference numeral. “1” to “N” and “1” to “M” are abbreviated.

  The display system 1 includes an input terminal 10, a storage unit 20, a server device 30, and a display device 80. Between the input terminal 10, the storage unit 20, the server device 30, and the display device 80, a network NW Communication via is performed. The network NW includes, for example, a WAN (Wide Area Network), a public line, a VPN (Virtual Private Network), and a LAN (Local Area Network).

  The display device 80 has an input terminal function, a storage unit function, a processing function, and a display function, and can also transmit and receive schedule information individually.

  The storage unit 20 is a storage device such as a RAM (Random Access Memory), a HDD (Hard Disk Drive), or a flash memory.

  The input terminal 10 is a device that allows the user U to register schedule information. The user U inputs schedule information using the input terminal 10 and transmits the input information to the server device 30.

  The storage unit 20 stores schedule information and usage authority information. FIG. 2 shows an example of schedule information, and FIG. 3 shows an example of usage authority information. As shown in FIG. 2, the schedule information includes, for example, schedule information for each person, date and time (in the figure, 20YY / MM / DD, 8 o'clock to 18 o'clock), and the like.

  The schedule information may also include location information. Furthermore, usage authority information is stored in the storage unit 20. As shown in FIG. 3, the usage authority information is information in which a user is associated with a person who can register a schedule. For example, as shown in the figure, users A and B can register schedules for the persons A to C, but the user C cannot register schedules for the persons A and B. For this reason, the server device 30 determines that registration is not possible when the user C makes a schedule registration application for the persons A and B.

  The server device 30 includes a control unit 34 and a communication unit 32. The communication unit 32 communicates with the input terminal 10 and the display device 80 via the network NW. The control unit 34 processes information acquired via the communication unit 32 based on the information stored in the storage unit 20.

  Further, the control unit 34 stores the processing result in the storage unit 20. For example, the control unit 34 receives schedule information input by a user and updates the schedule information stored in the storage unit 20. In addition, the control unit 34 transmits the schedule information stored in the storage unit 20 to the display unit 50.

  The display unit 50 is installed in, for example, a workplace office or a home living room, and displays a calendar, an image, and the like including schedule information of people and family members in the same department.

  FIG. 4 is a diagram illustrating an external configuration of the display unit 50. FIG. 5 is a diagram illustrating a functional configuration of the display device 80. The display device 80 includes, for example, a touch panel operation unit 52, a reading unit 58, a power supply unit 59, a control unit 60, a communication unit 70, and a display unit 50.

  The control unit 60 is a software control unit that functions when a processor such as a CPU provided in the display device 80 executes a program stored in a program memory. Further, a part or all of the control unit 60 may be a hardware function unit such as an LSI (Large Scale Integration) or an ASIC (Application Specific Integrated Circuit).

  The touch panel operation unit 52 outputs a signal corresponding to the operation to the control unit 60 when operated by the user.

  The reading unit (accepting unit) 58 reads information from identification information unique to the user or a medium presented by the user. The reading unit 58 is an IC card reader that reads information stored in an IC card presented by a user by performing short-range wireless communication, for example.

  When an ID card such as an employee ID card presented to the user is brought closer, the reading unit 58 activates an IC (Integrated Circuit) chip included in the ID card to perform wireless communication. The reading unit 58 acquires information stored in the IC chip by wireless communication, and outputs the acquired information to the control unit 60.

The reading unit 58 may be a magnetic information reading unit that reads magnetically stored information, an operation unit provided with a plurality of push buttons, face authentication, voice authentication, fingerprint authentication, or the like. By using these authentication systems, it is possible to selectively display the schedule of a specific authenticated individual.

  The power supply unit 59 supplies power to the touch panel operation unit 52, the reading unit 58, the communication unit 70, and the display unit 50. For example, a primary battery or a secondary battery. The power supply unit 59 may be electrically connected to an external power supply. In this case, the power supply unit 59 provides power supplied from an external power supply to each unit.

  The control unit 60 includes a display control unit 62 and an information processing unit 64. The display control unit 62 causes the display unit 50 to display an image based on the information transmitted from the server device 30. The displayed image is an image corresponding to information transmitted from the server device 30.

  The information processing unit 64 acquires information from the touch panel operation unit 52 and the reading unit 58 and transmits the acquired information to the server device 30 via the communication unit 70. The communication unit 70 communicates with the server device 30 via the network NW.

  The display device 80 displays various information such as images and characters based on signals output from the control unit 60. Examples of the display unit 50 of the present embodiment include electronic paper. Electronic paper is a display medium with the visibility and portability that is the advantage of paper, and the display content can be electrically rewritten, and it can be folded to some extent, without the need for a backlight. It has less power consumption than other displays such as a liquid crystal panel, and has a memory property that can maintain display contents even if the power is turned off once rewritten.

  The display unit 50 can partially rewrite the image. The configuration of the display unit 50 will be described later. The size of the display unit 50 is selected according to the amount of data to be displayed, ease of viewing, and usage, but it is preferably about the same size as a normal calendar.

  FIG. 6 is a sequence diagram showing a flow of processing for displaying schedule information on the display device 80. First, the server device 30 acquires schedule information input by the user from the input terminal 10 (step S100).

  Next, the server device 30 reads the information stored in the storage unit 20 based on the acquired information, and updates the read information (step 102). The update is a process of storing the schedule information input by the user by the server device 30 in the area corresponding to the schedule information stored in the storage unit 20. As a result, the schedule input by the user is registered.

  Next, the server device 30 extracts schedule information corresponding to the display device 80 of the transmission destination from the usage information stored in the storage unit 20 (step S104). Next, the server device 30 generates a display signal based on the input schedule information, and transmits the generated display signal to the display device 80 (step S106).

  Note that the display signal is a signal corresponding to an image to be displayed on the display device 80. Next, the display control unit 62 of the display device 80 causes the display unit 50 to display schedule information based on the display signal (step S108). Thereby, for example, as shown in FIG. 4, the display unit 50 displays schedule information corresponding to a predetermined person.

  Person A must have a schedule at 8:00 of 20YY / MM / DD whose information has been updated, and have a schedule in the time zone from 9:00 to 11:00 and from 13:00 to 15:00. Can be recognized by the user from the image displayed on the display unit 50.

  Step S <b> 110 is processing in which the display device 80 transmits a request signal to the server device 30. The request signal is a signal that requests the server device 30 to transmit a display signal. For example, when the touch panel operation unit 52 illustrated in FIG. 5 is operated by the user, the display device 80 generates a request signal and transmits the generated request signal to the server device 30 (step S110).

  Next, when acquiring the request signal, the server device 30 extracts schedule information corresponding to the person stored in the storage unit 20 (step S112), generates a display signal based on the extracted schedule information, and generates the display signal. A display signal is transmitted to the display device 80 (step S114).

  Next, the display control unit 62 of the display device 80 causes the display unit 50 to display schedule information based on the display signal (step S116). That is, the display unit 50 displays schedule information when the touch panel operation unit 52 is operated by the user. Thereby, the process of this flowchart is complete | finished.

  For example, in general, other display devices using a liquid crystal display or an organic EL display an image on the display unit by applying a voltage. For this reason, in order to display an image for a long time, a connection with an external power source and a facility such as a battery having a large capacity are required. Also, the battery may need to be charged or replaced every few hours or every few days.

  On the other hand, in the present embodiment, the display device 80 uses a reflective display device. As the reflective display device, a reflective liquid crystal display device, an electrochromic display device, an electrophoretic display device, or the like can be used. The reflective liquid crystal display device can significantly reduce power consumption as compared with the transmissive liquid crystal display device because the backlight is unnecessary.

  In addition, when an electrochromic display device and an electrophoretic display device display an image, they can hold the displayed image without using power for a long period of time (for example, one year). For this reason, for example, by updating the image to be displayed on the display unit 50 at a predetermined interval (for example, 1 to 10 minutes), even when using a battery that can be used only for several hours or days on other display devices, several months or more, The image can be updated every predetermined time, and the updated image can be displayed.

  Note that the power consumed by the display unit 50 can be reduced as the communication with other devices or the frequency of image switching is lower. Further, when the frequency of communication with other devices or image switching is decreased, the user switches the time (information update time) when the image included in the image displayed on the display unit 50 is changed, and the time when the user uses the image. And the reliability of the information displayed on the image can be determined. In this case, the user can acquire highly reliable information by updating the image as necessary.

  Further, the schedule can be canceled using the display device 80. For example, when the planned outing is postponed, for example, when the touch panel operation unit 52 is operated by the user, the display control unit 62 controls the display unit 50 to display the inquiry image.

  When an operation corresponding to the displayed image is performed by the user, a signal corresponding to the operation is transmitted to the server device 30. The server device 30 executes processing based on a signal corresponding to the operation. In this case, the server device 30 stores a signal corresponding to the operation and a process in association with each other.

For example, when the ID card is presented by the user, the server device 30 determines whether the identification information read from the ID card matches the identification information of the scheduled person, and the identification information matches. If you cancel the appointment. In addition, when the touch panel operation unit 52 is operated by the user, the server device 30 presents the user's schedule information to the user and inquires whether or not to newly register the schedule. Is displayed on the display unit 80.

  In addition, when the touch panel operation unit 52 is operated by the user to perform a schedule update display, the server device 30 causes the display unit 80 to display an image indicating schedule update information.

  Note that instead of the display device 80 transmitting a signal corresponding to the operation to the server device 30, the control unit 60 of the display device 80 may cause the display unit 50 to display an inquiry image based on the user's operation. Good. Further, the control unit 60 of the display device 80 may transmit a signal instructing the server device 30 to perform processing based on a user operation input.

  In this case, the control unit 60 of the display device 80 displays an inquiry image on the display unit 50 based on, for example, a user operation, or instructs the server device 30 to process a signal corresponding to the operation input. An application program that converts signals is installed.

  FIG. 7 is a sequence diagram relating to processing when a user who has not registered a schedule registers a schedule via the display device 80. When the personal schedule is not registered, the schedule display unit 50 is blanked by the display device 80. In the present embodiment, a case where the user performs schedule registration via the display device 80 in this case will be described.

  First, the reading unit 58 of the display device 80 stands by until an ID card is presented by the user (step S160). When the ID card is presented by the user, the reading unit 58 reads the identification information of the user stored in the IC chip of the ID card, and transmits the read identification information of the user to the server device 30 (step). S162).

  Next, the server device 30 determines whether or not the identification information matches the identification information stored in the storage unit 20 with reference to the transmitted identification information, and has a schedule for a predetermined time (for example, 30 minutes). It is determined whether it is free (step S164). The server device 30 refers to, for example, the current time and the time when the schedule is entered, and determines whether the schedule can be entered for a predetermined time (for example, 30 minutes).

  If there is a plan within a predetermined time from the current time, the schedule cannot be registered. When the server device 30 determines that the identification information matches and schedule registration for a predetermined time can be entered, the server device 30 reflects and stores the schedule registration for the predetermined time in the information stored in the storage unit 20.

  As a result, the schedule registration is performed by the user who presented the ID card. Next, the server device 30 transmits a display signal for causing the display device 80 to display information indicating schedule registration to the display unit 50 (step S166).

  Next, the display control unit 62 of the display device 80 acquires the display signal transmitted from the server device 30, and causes the display unit 50 to display an image based on the acquired display signal (step S168). For example, when the user presents an ID card (step S160), it is assumed that the display device 80 displays that there is no schedule in the schedule and that the current schedule is empty.

  When the user U presents the ID card in this state, the display device 80, based on the determination result of the server device 30, determines a predetermined time from the current time “20YY / MM / DD 9:00” (for example, “9:00”). ~ 9: 30 "), it is displayed that the schedule is entered.

  FIG. 8 is a diagram illustrating an example of a cross-sectional view of the display unit 50. An example of the configuration of the display unit 50 will be described with reference to FIG. The display unit 50 includes a plurality of reflective pixel electrode units 84 on a substrate 82, and a liquid crystal layer 86 is stacked thereon. On the liquid crystal layer 86, a transparent electrode layer 88, an ink fixing layer 90, a color filter 92, and a protective film 94 are laminated in this order.

  The reflective pixel electrode portion 84 is electrically connected to a switching element such as a thin film transistor (TFT). The reflective pixel electrode portion 84 turns on / off the switch with the transparent electrode layer 88 according to the driving of the switching element. Each of the plurality of reflective pixel electrode portions 84 has a corresponding switching element, and a voltage is applied by driving the corresponding switching element.

  The driving of the switching element is controlled by the control unit 60. As a result, a voltage can be applied to the specific reflective pixel electrode portion 84, so that the liquid crystal layer 86 corresponding to the specific reflective pixel electrode portion 84 is driven. That is, the display device 80 can rewrite information only in a predetermined area on the display surface.

  The transparent electrode layer 88 is a common electrode whose entire surface has the same potential. The transparent electrode layer 88 is formed of, for example, a conductive oxide such as a transparent electrode layer (ITO film). The ink fixing layer 90 is formed of, for example, transparent glass or resin. The ink fixing layer 90 is made of, for example, an insulating material. The protective film 94 is laminated on the color filter 92 to protect the color filter 92.

  The color filter 92 will be described. The color filter 92 is formed, for example, by applying ink to the ink fixing layer 90.

  FIG. 9 is a perspective view of the display unit 50. The color filter 92 is, for example, one pixel of four subpixels (first subpixel (1), second subpixel (2), third subpixel (3), and fourth subpixel (4)). Form. One pixel corresponds to one reflective pixel electrode portion 84.

  The arrangement of the color filter 92 may be selected for each area of the display surface from among a mono color type, a double color type, a full color type, and a monochrome type, which will be described below, or any one type may be selected. Good.

<Mono color type>
A mono-color type will be described with reference to FIG. The mono-color type color filter 92 includes two sub-pixels having a complementary color relationship and a transparent transparent sub-pixel. The two sub-pixels having a complementary color relationship are, for example, a red sub-pixel 92R that is red and a cyan sub-pixel 92C that is cyan. The complementary color relationship of the color filter 92 is not limited to red and cyan, but may be a combination that becomes white by mixing colors such as magenta and green, or yellow and blue.

  The complementary color relationship is, for example, L * a * b * (in which the hue of the colored portion of the color filter 92 is measured with transmitted light (reflected light) using a D65 light source which is a standard light source for measuring the color of an object. Elster, Easter, Baster) is an expression color.

  In this case, the hue of the colored portion is a hue obtained by measuring the colored pixels printed on the transparent substrate by transmission measurement. Further, the two-color sub-pixels having a complementary color relationship may be formed by a plurality of colored layers having different colors.

  As shown in the figure, the four sub-pixels are a red sub-pixel 92R (first sub-pixel) and a cyan sub-pixel 92C (third sub-pixel) that are diagonal, and two transparent sub-pixels 92T-A (second sub-pixels). And the transparent sub-pixel 92T-B (fourth sub-pixel) are arranged diagonally. The cyan sub-pixel 92C has a colored region 92C-C and a non-colored region 92C-S, and the non-colored region 92C-S is formed around the colored region 92C-C.

  FIG. 9A) shows a case where the display of the liquid crystal layer 86 facing the red sub-pixel 92R is black and the display of the liquid crystal layer 86 facing another sub-image is white. In this case, it is expressed by a mixed color of colors transmitted through the cyan sub-pixel 92C and the transparent sub-pixels 92T-A and 92T-B, and theoretically becomes a light cyan color. However, in actuality, it is visually recognized as a mixed color of light in which light red is also mixed due to coloring due to surface reflection on the red sub-pixel 92R.

  FIG. 9B) shows a case where the display of the liquid crystal layer 86 facing the red sub-pixel 92R is white, and the display of the liquid crystal layer 86 facing the cyan sub-pixel 92C and the transparent sub-images 92T-A and 92T-B is black. Is shown. In this case, since light is hardly reflected in the region corresponding to the cyan sub-pixel 92C and is expressed by a color transmitted through the red sub-pixel 92R, red is displayed.

  If the display of the liquid crystal layer 86 corresponding to one pixel is white, white is displayed, and if the display of the liquid crystal layer 86 corresponding to one pixel is black, black is displayed. In this way, the display unit 50 displays images, characters, and the like by the pixel electrode unit 84 being controlled by the control unit 60.

  When the above-described monochromatic color filter 92 is used, for example, white, black, and red can be displayed. In the mono-color type, white display can be achieved when the display of the liquid crystal layer 86 facing the color filter 92T is white and the display of the liquid crystal layer 86 facing the color filters 92C and 92R is black.

  In this case, white balance adjustment including the cyan sub-pixel 92C is very easy and natural white can be expressed as compared with the case of using a full color type color filter described later. In addition, the saturation of red display can be changed.

<Double color type>
In the example of FIG. 9, two colors that are not in a complementary color relationship may be used instead of the red sub-pixel 92R and the cyan sub-pixel 92C. Hereinafter, it is referred to as a double color type. In the double color type, white display is not possible, but the saturation of two colors that are not complementary colors can be displayed high.

  FIG. 10 is a diagram showing hue and saturation in the L * a * b * color system. For example, the first sub-pixel has a red color with a hue angle h1 in the range of −30 degrees to 45 degrees, and the third sub-pixel has a hue angle h2 of 210 degrees or more from the first hue angle h1. A blue color within a range of 300 degrees or less is assumed.

  As a result, it is possible to display red and blue with saturation that is easily noticed by the viewer. Further, the second subpixel or the fourth subpixel can be a transparent resin layer or a gap. Since the first sub-pixel and the third sub-pixel do not have a complementary color relationship, it is possible to display a vivid color with the third hue by mixing the colors.

For red and blue, purple can be displayed. Also, the warning color and the red color used for alerting can be displayed darkly. Of course, it is obvious that the same display can be performed even when the hue of the first sub-pixel and the hue of the third sub-pixel are reversed.

  The first sub-pixel has a red color with a hue angle in the range of 0 to 60 degrees instead of h1 and h2, and the second sub-pixel has a hue angle of the first hue. The hue angle may be a yellowish green color in a range where the hue angle moves from 60 degrees to 150 degrees. Thereby, green, red, and yellow which is a mixed color thereof can be displayed. Also, the warning color and the red color used for alerting can be displayed darkly.

  Further, in a state where the first color is provided in the first sub-pixel and the third color is provided in the third sub-pixel, the display of the liquid crystal layer 86 facing the first sub-pixel is set to white, When the display of the liquid crystal layer 86 facing the sub-pixel is black, the hue angle of the second color is a range in which the hue angle of the first color moves from 60 degrees to 150 degrees, or from 210 degrees to 300 degrees. It may be in a range that moved less than a degree.

  By having such a hue angle relationship, a dark color can be displayed even though the first color and the second color are not complementary.

<Full color type>
FIG. 11 is a diagram for explaining the full color type, and the display unit 50A is different in the configuration of the display unit 50 and the color filter 92 described with reference to FIG. The color filter 92 of the display unit 50A includes three primary colors and a transparent color. For example, it is composed of a red sub-pixel 92R, a green sub-pixel 92G, a blue sub-pixel 92B, and a transparent sub-pixel 92T.

  If the display of the liquid crystal layer 86 facing the color filter 92 is all white, all the light transmitted through the color filter 92 is reflected by the liquid crystal layer 86, and the red sub-pixel 92R, the green sub-pixel 92G, and the blue sub-pixel 92B are changed. White is displayed by the mixed color of the transmitted light.

  Further, as shown in the drawing, when the liquid crystal layer 86 corresponding to the red sub-pixel 92R is displayed in white, the light transmitted through the color filter 92 is reflected at the portion corresponding to the red sub-pixel 92R and is transmitted through the red sub-pixel 92R. Since it is not reflected in the portion corresponding to the other sub-image, red is displayed.

  In the full color type, the red sub-pixel 92R, the green sub-pixel 92G, and the blue sub-pixel 92B are used, and the number of transparent sub-pixels is small. Therefore, the reflectance of white display tends to be lower than that of the mono color. Become. In addition, the saturation of the displayed color tends to be lower than that of the mono color.

<Monochrome type>
When the color filter 92 is not provided, a monochrome type capable of displaying two colors of white and black is obtained. Thereby, white or black can be displayed darkly.

  As shown in the figure, out of the four sub-pixels, the first sub-pixel (1) 92B and the third sub-pixel (3) 92R are colored with the first color without including the transparent sub-pixels. The second sub-pixel (2) 92T-A and the fourth sub-pixel (4) 92T-B may be colored with the second color.

  FIG. 12 is a diagram for explaining the relationship between the image displayed on the display unit 50 and the color filter. In the display unit 50, for example, an area for displaying character information such as the area T10 is a monochrome display type and forms a display surface. Thereby, character information can be displayed clearly.

  In the display unit 50, for example, in a region where information is displayed using character information and color information, a color filter 92 of a mono color type, a double color type, or a full color type is used.

  For example, if the region T11 is formed in a full color type, color information corresponding to each person can be displayed from a plurality of colors generated by mixing the three primary colors, the schedule for Mr. A is red, the schedule for Mr. B is green, Mr. C's schedule can be yellow.

  Furthermore, it is preferable to use a double color type in an area where two colors are desired to be displayed with high saturation. Thereby, color information can be displayed with high saturation.

  Note that the display control unit 62 may acquire a signal transmitted from the server device 30 and display an image corresponding to the acquired signal on the display unit 50. In this case, the configuration of the color filter 92 of the display unit 50 is stored in the storage unit 20 in advance, and the server device 30 uses the configuration of the color filter 92 stored in the storage unit 20 and the image to be displayed on the display unit 50. Based on this, a signal is generated.

  Further, the control unit 60 of the display device 80 may store the configuration of the color filter 92 of the device itself, and cause the display unit 50 to display an image based on an image display signal transmitted from the server device 30.

  The display device 80 described above can display the user's schedule information on the display unit 50 based on the display signal transmitted from the server device 30. In addition, the display device 80 can transmit information acquired from the user to the server device 30, and can display information indicating whether the schedule can be registered on the display unit 50 based on the information returned from the server device 30. .

  As a result, it is possible to make the user visually recognize the schedule information of each person and whether or not the schedule can be registered while suppressing power consumption.

  Moreover, since the display part 50 can rewrite the image displayed on one part area | region among the display areas which display an image, it can suppress power consumption. In addition, the display unit 50 can display the information with higher visibility because the display unit 50 can display the image by changing the hue and saturation for each region in which the image is displayed while suppressing power consumption.

  The present invention displays a calendar having an individual or a plurality of schedule display units, and as a display device and display system capable of inputting a schedule from a long distance using an electronic device such as a smartphone or a personal computer, It can be applied to various uses such as industrial display devices.
