Description

  The present invention relates to a display device.

  Conventionally, there has been a demand for a portable color display device that is small in size, has low power consumption, and has less eye fatigue compared to a liquid crystal display. In this prior art display device, there is a transparent film of cyan, magenta and yellow on a white plate 5 which is a fixed portion, and one end of a cantilever movable film having this three-layer film as a display portion is attached to the substrate. It is fixed. Further, the movable electrode portion on the movable film has a potential difference with the fixed drive electrode, and can be moved by electrostatic force. Arbitrary information can be displayed by this, and matrix display can be performed by arranging the movable film and the fixed drive electrodes in a lattice pattern.

And a control device.

  In the display device according to the first aspect of the present invention, a plurality of display portions serving as a base are arranged in a matrix. In addition, the color member moves into the display unit through the openings formed in these display units, and the portion that has moved into the display unit of the color member spreads to display the color on the display unit. Further, the color of the display unit is changed by the movement of the color member by the actuator whose operation is controlled by the control device. For this reason, there is little eye fatigue compared with a liquid crystal display. In addition, since the color member has a simple structure that does not require high-precision processing and positioning, the manufacturing cost can be reduced.

  According to a second aspect of the present invention, in the display device according to the first aspect, there are a plurality of openings formed in the display unit, and the color members having different colors are provided in the respective openings.

  In the display device according to the second aspect of the present invention, since there are a plurality of openings formed in the display section, and color members of different colors are provided in each opening section, display of a plurality of colors is possible.

  According to a third aspect of the present invention, in the display device according to the second aspect of the present invention, the display section serving as the base is white and the three openings are provided, and the color member is a color of cyan, magenta, and yellow. It is a member.

  In the display device according to the third aspect of the present invention, the display portion as a base is white and has three openings, and the color member is a color member of cyan, magenta, and yellow. Color display is possible by subtractive color mixture.

  According to a fourth aspect of the present invention, in the display device according to any one of the first to third aspects, the color member is composed of a plurality of wire rods arranged so that a tip portion protruding from the opening portion spreads. .

  In the display device according to the fourth aspect of the present invention, since the color member is composed of a plurality of wire rods arranged so that the tip portion protruding from the opening portion is widened, the configuration of the color member is simplified.

  Since the display device of the present invention has the above-described configuration, the display device has an excellent effect that there is less eye fatigue than a liquid crystal display and the manufacturing cost can be suppressed.

  Next, as shown in FIG. 6, when only the cyan color member 22 is moved in the direction of the arrow A by the actuator 42 by the control signal output from the control device 44, the cyan color member 22 is configured. A plurality of wire rods 32 project from the opening portion 14, and the distal end portion 32 </ b> A expands inside the display portion 12, thereby displaying cyan on the display portion 12.

  Similarly, when only the magenta color member 24 is moved in the direction of the arrow A by the actuator 42, the plurality of wire members 34 constituting the magenta color member 24 protrude from the opening 16, and the inside of the display unit 12. Magenta is displayed on the display unit 12 by expanding the distal end portion 34A.

  Further, when only the yellow color member 26 is moved in the direction of arrow A by the actuator 42, a plurality of wire rods 36 constituting the yellow color member 26 protrude from the opening 18, and the tip ends inside the display unit 12. As the part 36A spreads, yellow is displayed on the display part 12.

  On the other hand, as shown in FIG. 7, when the cyan color member 22 and the magenta color member 24 are moved in the direction of arrow A by the actuator 42, the plurality of wire rods 32 constituting the cyan color member 22 are Projecting from the opening 14, the tip 32 </ b> A expands inside the display unit 12, and a plurality of wires 34 constituting the magenta color member 24 project from the opening 16, and the tip 34 </ b> A expands inside the display 12. Blue color is displayed by mixing.

  Similarly, when the other two color members are moved in the direction of arrow A by the actuator 42, a plurality of wire members constituting the other two color members protrude from the opening, and the tip ends inside the display unit 12. Red and green are displayed as the part spreads and mixes with each other.

  Furthermore, as shown in FIG. 8, when the cyan color member 22, the magenta color member 24, and the yellow color member 26 are moved in the direction of the arrow A by the actuator 42, the three color members 22, 24, A plurality of wire rods 32, 34, and 36 constituting 26 protrude from the openings 14, 16, and 18, and the tip portions 32 </ b> A, 34 </ b> A, and 36 </ b> A spread and mix with each other inside the display unit 12 to display black.

  As described above, in the display device 10 according to the present embodiment, the color members 22 and 24 projecting into the display unit 12 from the openings 14, 16 and 18 formed on the bottom surfaces 12 </ b> A of the plurality of display units 12 arranged in a matrix. , 26, the tip portions 32A, 34A, 36A of the plurality of wire rods 32, 34, 36 spread within the display unit 12 to display colors on each display unit 12. For this reason, there is little eye fatigue compared with a liquid crystal display. Further, in the display device 10 of the present embodiment, the color members 22, 24, and 26 are moved through the openings 14, 16, and 18 by the actuator 42 whose operation is controlled by the control device 44, whereby the display unit 12. The color changes. For this reason, since it is a simple structure which does not require highly accurate processing and positioning in a color member, manufacturing cost can be held down.

  Further, in the display device 10 of the present embodiment, the bottom surface 12A of the display unit 12 serving as a base is white and there are three openings 14, 16, and 18, and the color members 22, 24, and 26 are cyan, magenta, and yellow.
