By adjusting this initial value, the first page of the book can always be displayed at the start of browsing, or the page displayed at the end of the previous browsing can be displayed first.

  The focus counter information 16 is screen information for counting the selected object. The focus counter information 16 is incremented when the cursor is moved to the next object by operating the direction key, and decremented when the cursor is moved to the previous object.

  The display 2a is a dual-view liquid crystal or a triple-view liquid crystal, and can simultaneously display two screens that can be visually recognized by changing the viewing direction of the display surface.

<Triple view LCD>
3 and 4 are explanatory diagrams schematically showing an operation example of the triple view liquid crystal. FIG. 3 shows how the composite image 21 is created from three different images A to C, and FIG. 4 shows how different images are visually recognized according to the first to third viewing directions. It is shown. The triple-view liquid crystal includes a liquid crystal panel 22 that displays a composite image 21 of three different images A to C, and a control panel 23 that changes a visible image according to a direction (viewing direction) in which the liquid crystal panel 22 is viewed. The display device is configured to display only one image with respect to a specific viewing direction.

  The composite image 21 is formed by dividing each of the images A to C in FIG. 3A into a plurality of vertically long and narrow rectangular blocks, and alternately arranging these blocks one by one (FIG. 3). 3 (b)). In this example, the blocks are arranged in the order of the first block of image A, the second block of image B, the third block of image C, the fourth block of image A,. .

  The control panel 23 is a parallax barrier in which a large number of slit-shaped transparent regions 25 are formed in an opaque region 24. When the composite image 21 is displayed on the liquid crystal panel 22, a different image is selected according to the viewing direction. Visually.

  In this example, the transparent regions 25 (slits) are arranged at a rate of one for every three pixels. Since the field of view is limited by the presence of such a slit layer, it is possible to simultaneously display a plurality of visually recognizable images by changing the viewing direction.

  That is, when viewing the display 2a from the first viewing direction with the front direction of the display surface as the first viewing direction, the image B is viewed. Further, when viewing the display 2a from the second viewing direction with the diagonally right direction (right viewing direction) as the second viewing direction, the image A is viewed. Further, when the display 2a is viewed from the third viewing direction with the left oblique direction (left viewing direction) as the third viewing direction, the image C is viewed.

<Dual View LCD>
5 to 7 are explanatory diagrams schematically showing an operation example of the dual view liquid crystal. FIG. 5 shows an example of a pixel arrangement in the case where a color image is displayed using three pixels to which RGB luminance information is assigned as a constituent unit. FIG. 6 shows a state in which gray (gray) gradation is expressed using two adjacent pixels. FIG. 7 shows a state where a monochrome image is visually recognized when the display surface is viewed from an oblique direction by correcting the luminance value.

  The dual-view LCD is a display device that simultaneously displays two images that can be viewed by changing the viewing direction of the liquid crystal panel, and displays different images depending on whether the display surface is viewed from an oblique direction or from the front. can do.

  In general, a color image is displayed by a number of blocks each having three pixels each having RGB luminance information assigned thereto as a constituent unit. In this example, blocks in which three pixels are arranged in the horizontal direction are arranged in a matrix of 3 rows and 3 columns.

  In a state before correcting the luminance value of each pixel, the visibility, that is, the visibility, changes depending on the viewing angle of the display surface, but the image is viewed as one image when viewed from any direction.

  On the other hand, when expressing gray gradation using two adjacent pixels, a pattern in which white (luminance level 0%) is assigned to one pixel and black (luminance level 100%) is assigned to the other pixel (FIG. 6). (A)) and a pattern (FIG. 6B) in which gray (brightness level 50%) is assigned to both pixels can be considered.

  When the display surface is viewed from the front, a gray gradation with a luminance level of 50% is visually recognized regardless of the pattern. However, when the display surface is viewed from an oblique direction, the visible color of the pattern of FIG. 6A changes more greatly depending on the viewing angle than the pattern of FIG. 6B due to visual characteristics. Specifically, it looks darker as the inclination from the front direction increases.

  In this way, by properly using two values of a pattern having a large luminance difference between adjacent pixels and a small pattern, a monochrome image different from a color image viewed from the front direction can be viewed from an oblique direction.

  FIG. 7A shows a pixel array in which the luminance value is corrected in units of two adjacent pixels, and FIG. 7B shows an example of a monochrome image visually recognized by correcting the pixel value. Yes. In this example, the luminance difference between the two central pixels is made larger than that of the other pixels. Accordingly, when viewed from the front direction, a color image similar to that before the luminance value correction is visually recognized, and when viewed from an oblique direction, a monochrome image having a black center is visually recognized.
