To get. The casing constituting the outer wall portion of the lid 29 in the open state is a liquid crystal that is a general power supply image display means (second display means) that consumes power while the image display state is maintained. A display (LCD) 27, a speaker 28, and the like are provided. As the liquid crystal display (LCD) 27, for example, a TFT (Thin Film Transistor) type liquid crystal display or the like having a high-speed drawing function is used. The casing constituting the outer wall portion of the main body 30 is provided with keys 21 to 25 constituting the key operation portion, a microphone 26, and the like. The key operation unit including these keys 21 to 25 and the normal liquid crystal display (LCD) 27 as the power feeding image display means (second display means) are in the casing in the open state that can be operated by the user. Are provided on the outer wall portion on the side facing the user. Accordingly, the user can operate the keys 21 to 25 of the key operation unit while looking at the screen of the liquid crystal display 27.

Also, the externally exposed portion of the upper casing on the lid 29 side that is exposed to the outside in the closed state, that is, the outer wall portion (front portion) on the LCD 27 side of the two opposing surface portions of the upper casing. As shown in FIG. 1B, a display panel 31 that functions as a non-powered image display means (first display means) is provided on the opposite outer wall (back face). The display panel 31 is located at a position where the user can easily see when the display panel 31 is in the closed state, and is located at a position where the user is difficult to see when the user operates the key operation unit in the open state.
The display panel 31 can change the display image by receiving a drawing drive signal for switching the display image, and can maintain the display state of the image even in a non-powered state.

  FIG. 2A is a cross-sectional view showing a configuration example of the display panel 31 in the mobile phone 20 of the present embodiment. The display panel 31 is formed using cholesteric liquid crystal and is provided on the casing 290 of the lid portion 29. The display panel 31 has a three-layer structure including a transparent lower base material layer 311, a cholesteric liquid crystal layer 312, and a transparent upper base material layer 313. As the transparent lower base material layer 311 and the transparent upper base material layer 313, for example, a glass thin plate can be used. A row electrode 314 as a lower grid electrode is provided on the upper part of the transparent lower base material layer 311, that is, on the outer side of the mobile phone 20. A column electrode 315 is provided as an upper grid electrode. The column electrode 314 is composed of a large number of line-shaped electrodes with a predetermined pitch extending in parallel with the horizontal direction of the mobile phone 20 (the horizontal direction in FIG. 1), and the end portions of these line-shaped electrodes are drawn as described later. The output terminal of the unit 200 is connected. The column electrode 315 is composed of a large number of line-shaped electrodes with a predetermined pitch extending in parallel with the vertical direction (vertical direction in FIG. 1) of the mobile phone 20, and the end portions of these line-shaped electrodes are similarly drawn. It is connected to the output terminal of the processing unit 200. The row electrodes 314 and the column electrodes 315 are arranged over the entire display area 31 of the display panel 31 so that the extending directions of the electrodes are orthogonal to each other. Then, a drawing drive signal (electrical signal) is input to the row electrode 314 and the column electrode 315 at an appropriate ON / OFF timing from the drawing processing unit 200 described later, so that the row electrode 314 at an arbitrary point in the display region 31 The potential difference with the column electrode 315 can be controlled.

  As shown in FIG. 2B, the cholesteric liquid crystal 312 enables full color expression by selectively reflecting light having a wavelength determined according to the helical period L of the molecular arrangement in the incident light. Yes. Since the helical period L of the molecular arrangement generally becomes smaller as the temperature rises, a desired color can be expressed by temperature control. Also, the cholesteric liquid crystal 312 can fix the helical period L of the molecular arrangement by rapidly cooling. Therefore, after fixing the helical period L, the color can be fixed. Due to such characteristics, the display panel 31 using the cholesteric liquid crystal 312 consumes power to supply a drawing drive signal for temperature control when performing a drawing process for switching a display image. After being done, it is possible to continue displaying images without power.

  The display panel that can maintain the display state of the image even in a non-powered state is not limited to the cholesteric liquid crystal, and may be, for example, a ferroelectric liquid crystal.

  FIG. 3 is a cross-sectional view of a display panel 31 according to another configuration example. The display panel 31 is provided on the casing 290 of the lid 29 and has a four-layer structure including a transparent lower base material layer 316, an image recording layer 317, a transparent upper base material layer 318, and a protective layer 319. A row electrode 314 as a lower grid electrode is provided above the transparent lower base material layer 316, that is, outside the mobile phone 20, and below the transparent upper base material layer 318, that is, inside the mobile phone 20, A column electrode 315 is provided as an upper grid electrode. The row electrode 314 is composed of a large number of line-shaped electrodes having a predetermined pitch extending in parallel with the horizontal direction of the mobile phone 20 (the horizontal direction in FIG. 1). Is connected to the output terminal. The column electrode 315 is composed of a large number of electric wires having a predetermined pitch extending in parallel with the vertical direction (vertical direction in FIG. 1) of the mobile phone 20, and the end portions of these line electrodes are similarly drawn in the drawing processing unit. It is connected to 200 output terminals. The row electrodes 314 and the column electrodes 315 are arranged over the entire display area 31 of the display panel 31 so that the extending directions of the electrodes are orthogonal to each other. Then, by inputting a drawing drive signal (electrical signal) with appropriate ON / OFF timing from the drawing processing unit 200, the potential difference between the row electrode 314 and the column electrode 315 at an arbitrary point in the display region 31 is controlled. it can.

  The image recording layer 35 can control the visible state of the point by the potential difference applied between the row electrode 38 and the column electrode 39, and no electric signal is input from the drawing processing unit 200. However, what maintains the visible state can be used. For example, a large number of white particles and black particles are encapsulated in a transparent microcapsule, and these are arranged at all points (pixel points) where the electric wires of the row electrode 314 and the column electrode 315 intersect each other. The recording layer 317 can be used. In this case, the white particles and the black particles in each microcapsule are charged with opposite polarities. For example, a negatively charged substance is used as white particles, and a positively charged substance is used as black particles. When an electric signal is input from the drawing processing unit 200 and the potential of the row electrode 314 at a certain pixel point is negative and the potential of the column electrode 315 is positive, black particles are aligned in the microcapsules at that pixel point. Electrophoresis is performed on the electrode 315 side, and white particles are electrophoresed on the row electrode 314 side. As a result, when this pixel point is viewed from the outside of the mobile phone 20, the pixel point appears black. Conversely, pixel points when the potential of the row electrode 314 is positive and the potential of the column electrode 315 is negative appear white. By performing such drawing control over the entire display area 31, a desired monochrome image can be displayed in the display area 31. In addition, the arrangement of the black particles and the white particles in each microcapsule is maintained even when the electric signal is not input from the drawing processing unit 200. Therefore, the display panel 31 can maintain the once displayed image as it is even in the non-powered state. In addition, a multi-tone monochrome image can be displayed in accordance with an electric signal input from the drawing processing unit 200.

  Although a monochrome image has been described here, a color image can also be displayed. As a specific example for displaying a color image, a color filter layer is provided between the transparent upper substrate layer 318 and the protective layer 319. When three color filters of R (red), G (green), and B (blue) are used as the color filter layer, three adjacent to each other among the points where the row electrode 314 and the column electrode 315 intersect each other. A point is treated as one pixel. Then, a color filter layer is provided so that the R, G, and B filter portions face each other at these three points. Thus, for example, when a certain pixel is red, white particles migrate to the column electrode 315 side for the microcapsules facing the R filter portion, and for the microcapsules facing the G filter portion and the B filter portion. A drawing drive signal (electric signal) is inputted so that the black particles are electrophoresed to the column electrode 315 side.

  The display panel 31 that can be used in the present invention can be used as long as the display image can be switched and the display state of the display image can be maintained even in a non-powered state. For example, other known electronic paper that can change the display image by receiving a drawing drive signal (electrical signal) for switching the display image and can maintain the display state of the image even in a non-powered state is used. Can do.

The drawing processing unit 200 includes a drive control signal generation unit 201, a column electrode drive unit 202, and a row electrode drive unit 203. Based on the image data sent from the main control unit 210 or the drawing data of each pixel of the entire screen of the display panel, the drive control signal generation unit 201 sends data from the column electrode drive unit 202 and the row electrode drive unit 203 to the display panel 31. A drive control signal for controlling the drawing drive signal to be output is generated. The column electrode driver 202 supplies a drawing drive signal to a predetermined column electrode 315 based on the column electrode drive control signal received from the drive control signal generator 201. Further, the row electrode driving unit 203 supplies a drawing drive signal to a predetermined row electrode 314 based on the row electrode drive control signal received from the drive control signal generation unit 201.
