For example, the optical writable electronic paper EP displays image information on the liquid crystal panel 10 and irradiates the electrode 14 with the light writable electronic paper EP over the liquid crystal panel 10 while applying a voltage from an external power source. Thus, the image information displayed on the liquid crystal panel 10 can be transferred to the display unit 12 and displayed and held.
That is, the optical writable electronic paper EP transfers the projected content image to the display unit 12 by applying a voltage to the electrode 14, and holds the content image in a display state even after the voltage applied to the electrode 14 is removed. It has the function to continue.

  The optical writable electronic paper EP includes an organic photoconductive material layer (organic photoconductive layer) 30 and a liquid crystal display material layer used in a copying machine, as shown in FIG. (Microencapsulated cholesteric liquid crystal layer) 31 is combined, these layers are sandwiched between a pair of front and back transparent electrodes 32, and this laminate is sandwiched between a pair of front and back transparent substrate films 33. In this configuration, the cholesteric liquid crystal layer 31 reflects white light, and the light passes through the liquid crystal layer 31 and is absorbed by the black layer 34 provided between the cholesteric liquid crystal layer 31 and the organic photoconductive layer 30. Black display monochrome image display is possible. Furthermore, since cholesteric liquid crystal has a characteristic of interference-reflecting color light according to the helical pitch, color display can be realized with a simple structure by forming the cholesteric liquid crystal layer 31 by laminating liquid crystals having different helical pitches. It is also possible.

  The optical writing type electronic paper EP displays, for example, an image to be transferred to a dimming element panel (light emitting panel) 10 for image writing, as shown in FIG. When the voltage is applied to the electrode 14, the intensity of light is instantaneously converted to the reflection density, and the projection image is held. The image information held in the display unit 12 can be erased by applying an erasing voltage to the electrode 14, and the optical writable electronic paper EP can be reused many times by repeating writing and erasing. Note that the optical writing type electronic paper EP does not perform such an erasing process, but applies the voltage to the electrode 14 as described above to project a new image, whereby image information held in the display unit 12 is stored. Can be overwritten and can be reused again and again by such overwriting.

  Therefore, the optical writing type electronic paper EP has the property of holding the image information transferred by the projection of the image with no power supply in addition to the thin property like paper, so that it is as if the paper used for a printer or a copying machine. It is a portable content display device that can be used and that can be reused repeatedly. Furthermore, the optical writing type electronic paper EP (display unit 12) can be used in the content distribution system of the present invention by combining with a writing device such as a printer having a communication function, a memory function, a control processing function, and the like. A terminal device can be configured.

Here, regardless of the self-writing type, optical writing type, or the like, as shown in FIG. 19, a processing device 39 in which the functional units of the processing unit such as a communication unit, a processor, and a memory are combined is configured to perform the processing. The device 39 may be detachably connected to the electronic paper display unit 2 (12) in a clip format or the like.
In the case of such a processing device 39, the battery provided in the electronic paper may be a capacitor that holds an electromotive force from an external device.

The present invention can also be applied to electronic papers other than formats such as self-writing type electronic paper and optical writing type electronic paper. For example, the electronic paper can be loaded into an external writing device and the display unit can be self-writing type. The image information may be written electronically. That is, the self-writing electronic paper is an example of an electronic paper that does not require an external image writing device, and the optical writing electronic paper is an example of an electronic paper that requires an external image writing device. .
In addition, as the display unit 2 (12) of the electronic paper EP, a liquid crystal having a memory property represented by a ferroelectric liquid crystal, an electrophoretic method in which charged particles are moved to switch a display, and charged particles are rotated. Alternatively, a particle rotation method for switching the display, a magnetophoresis method for switching the display by moving particles by magnetism, a thin battery-driven thin liquid crystal or an EL element may be used.
