The display device is a display device that is operated by a user touching an icon displayed on the touch panel 101, and includes a storage unit 104 that stores a plurality of different icon sizes, and an area touched by the user of the touch panel 101. By comparing the information on the area detected by the capacitance distribution detection unit 102 and the information on the icon size stored in the storage unit 104. A control unit 103 (selection unit) that selects an icon size of an icon displayed on the touch panel 101 from among a plurality of icon sizes stored in the storage unit 104. Moreover, the portable information device according to the present embodiment includes this display device.

  FIG. 2 is a plan view showing an example of the touch panel 101. The touch panel 101 is an electrostatic detection type touch panel, and has a display / sensor area 106 that performs information display and contact detection in a central portion. Further, a wiring region 107 in which electrodes and wirings for causing the display / sensor region 106 to function is provided in the peripheral portion of the touch panel 101. The display / sensor area 106 is composed of a predetermined number of X and Y coordinates with the lower left as the origin of coordinates. The touch panel 101 outputs the coordinates of the area touched by the user.

  Returning to FIG. 1, the capacitance distribution detection unit 102 detects an area where the user touches the touch panel 101. The control unit 103 is a CPU that controls the device. The storage unit 104 stores information such as device control programs, icon images, and screen layouts. The display control unit 105 is a driver for the touch panel 101.

  FIG. 3 shows an example of the reference size of the icon. FIG. 4 shows an example of a screen layout corresponding to each icon in FIG. The storage unit 104 stores information regarding a plurality of different icon sizes as shown in FIG. The figure shows three types of icon sizes: large, medium, and small. In this example, since the icon shape is a rectangle, the length of the side in the X direction and the length of the side in the Y direction are stored in the storage unit 104 as information on the icon size.

  Further, the storage unit 104 stores a screen layout corresponding to each icon size as shown in FIG. That is, the storage unit 104 stores a plurality of patterns corresponding to a plurality of icon sizes for the layout of the screen displayed on the touch panel 101.

  In the case of the icon size (large), for example, four large icons are displayed in the center of the screen. At the top and bottom, scroll buttons for scrolling the screen up and down are provided. In FIG. 4, the icons A, B, C, and D are displayed on the screen, but when the scroll button in the downward direction is pressed, the icons C, D, E, and F are displayed on the screen. When the scroll button in the upward direction is pressed in this state, the icons A, B, C, and D are displayed again.

  In the case of the icon size (medium), for example, nine icons A to I are displayed on the screen. Further, since the icon size is smaller than the case of (large), an icon explanation area for supplementary explanation of the function corresponding to the icon may be provided. In the case of the icon size (small), for example, 16 icons from A to P are displayed on the screen. In this case, since the icon size is further smaller than (middle), it is preferable that there is an icon explanation area as in (middle).

  An example of the operation of the display device shown in FIG. 1 will be described with reference to the flowchart of FIG. First, a function (program) for adjusting the icon size stored in the storage unit 104 is called by a predetermined operation. The following is processing of the icon size adjustment function. When the user touches a predetermined position on the touch panel 101, the sensor that constitutes the touch panel 101 determines the position on the sensor surface where the capacitor composed of the sensor and the human finger is present as a slight change in capacitance. To detect. This position is output to the capacitance distribution detector 102 as the capacitance distribution coordinates (step S101).

  For example, as shown in FIG. 6, the electrostatic capacitance distribution detection unit 102 defines a rectangle based on the outermost coordinates in the detected distribution, and uses the two coordinates of the diagonal as information on the rectangle (rectangular information). ) To the control unit (step S102). That is, the capacitance distribution detection unit 102 generates information regarding a rectangle having the minimum area that can include the area touched by the user as information on the area.

  Next, the control unit 103 compares the rectangle information with the icon size stored in the storage unit 104 (step S103). In the case of this embodiment, a rectangular area is calculated from diagonal coordinates and compared with the area of each icon size. Subsequently, the control unit 103 selects an icon size having an area closest to the rectangular area from among a plurality of icon sizes stored in the storage unit 104 (step S104). Then, the control unit 103 reads a screen layout pattern corresponding to the selected icon size from the storage unit 104 and sets the screen layout pattern to be displayed on the touch panel 101 (step S105). This is the end of the process of the icon size adjustment function.

  The effect of this embodiment will be described. In the present embodiment, an area where the user touches the touch panel 101 is detected. Then, the information on the area is compared with the icon size information stored in the storage unit 104. As a result, the icon size of the icon displayed on the touch panel 101 is selected from a plurality of predetermined icon sizes. Thereby, the icon of the icon size according to a user's characteristic can be displayed on the touch panel 101. FIG.

  Thus, according to the present embodiment, the size of the icon can be changed according to the habit of touching the touch panel 101 by the user (how it is touched). For this reason, for example, a large icon display can be applied to a person with a large finger, and a small icon display can be applied to a person who is dexterous with fine fingertips. Therefore, for many users, it is possible to provide a display device in which the operability of icons and the multiple display properties are well balanced.

  Further, the icon size of the icon displayed on the touch panel 101 is selected from predetermined icon sizes stored in advance in the storage unit 104. For this reason, operation | movement of the control part 103 is simplified compared with the case where an icon size is newly produced | generated at the time of icon display. In addition, a screen layout suitable for each icon size (see FIG. 4) can be stored in advance in the storage unit 104 in association with the icon size. Thereby, the operation of the control unit 103 required for determining the screen layout is also simplified.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, an example has been described in which the control unit 103 selects an icon size having an area closest to the rectangular area defined by the capacitance distribution detection unit 102. However, the control unit 103 may select an icon size having a long side closest to the long side of the rectangle. That is, the icon size may be selected based on the size in the horizontal direction when the area touched by the user is long in the horizontal direction and the size in the vertical direction when the region is long in the vertical direction. . When the rectangle is a square, the length of the long side is defined as the length of one side of the square.
