- the present invention is not limited to this.
- the timing at which the display start command is output to the liquid crystal display 3 may be slightly shifted.
- the force shown in the example in which the liquid crystal display 3 is brought into the transparent state after the entire image is displayed on the electrophoretic display 2 is not limited to this.
- the liquid crystal display 3 may be in a transparent state immediately before the entire image is displayed on the electrophoretic display 2.
- the electrophoretic display 2 is disposed on the back side and the liquid crystal display 3 is disposed on the front side, but the present invention is not limited to this.
- another memory display for example, a cholesteric liquid crystal
- the cholesteric liquid crystal is disposed on the front side
- the liquid crystal display 3 is disposed on the rear side
- the common electrode and the pixel electrode of the cholesteric liquid crystal are transparent electrodes. You may comprise so that a see-through is possible.
- the liquid crystal display 3 is set to the non-display state, so that only the image is displayed on the cholesteric liquid crystal so that the front side force can be visually recognized.
- the force shown in the example in which the electrophoretic display 2 starts displaying an image immediately after the user releases the continuous feed button 13 is not limited to this.
- the image display may be started after a certain period of time has passed since the continuous feed button 13 was released.
- the electrophoretic display 2 may be configured to be separable. That is, as shown in FIGS. 10 and 11, convex connection terminals are provided at the four corners on the lower surface of the upper frame portion 15 including the touch panel 14 and the liquid crystal display 3, and the lower frame including the electrophoretic display 2 is provided. A concave connection terminal is provided at each of the four corners of the upper surface of the part 16, and the corresponding connection terminals are fitted to each other so that data can be exchanged, thereby aligning the electrophoretic display 2 and the liquid crystal display 3.
- the display screen of the electronic book reader may be configured.
- the connection terminals by mating with the connection terminals in this way, it is possible to send information from the touch panel 14 and the page feed button 10 to the main control unit 101 and send information from the driver to the liquid crystal display 3. It becomes. Then, when searching for a desired image from a plurality of images, the electrophoretic display 2 and the liquid crystal display 3 are connected to display a plurality of images one after another on the displays 2 and 3. Can be searched at high speed. Also, when viewing the searched image, by separating the electrophoretic display 2 holding the image, the image held on the separated electrophoretic display 2 can be directly visually recognized. As a result, it is possible to prevent the visibility of the electrophoretic display 2 from deteriorating by seeing through the liquid crystal display 3.
- an example has been shown in which an image is always displayed on both the electrophoretic display 2 and the liquid crystal display 3, but the present invention is not limited to this.
- the electrophoretic display 2 The display of the image may be limited, and the image may be displayed only on the liquid crystal display 3.
- the image is also displayed on the electrophoretic display 2, and the characters can be read only by the display on the liquid crystal display 3.
- display of an image by the electrophoretic display 2 is limited, and power consumption by the electrophoretic display 2 can be reduced. Therefore, the power consumption of the e-book reader can be reduced without deteriorating the display quality.
