And a mobile phone with an imaging camera function (hereinafter simply referred to as “portable phone”) 300 that visualizes and displays the second image IM2 together with the first image IM1. For example, the liquid crystal display device 100 of the present embodiment constitutes the providing means and the liquid crystal display panel 110 of the present invention, and the liquid crystal panel 200 constitutes the liquid crystal panel 200 of the present invention. Further, for example, the mobile phone 300 of the present embodiment constitutes the visualization means of the present invention.

  The image display system S displays the first image IM1 by the liquid crystal display device 100 and transmits the first image IM1 by the liquid crystal panel 200, while rotating the optical rotation of polarized light that cannot be discerned by the human being by the liquid crystal panel 200. The second image IM2 is made to be a latent image in a partial area of the first image IM1 using the change of. In addition, when the mobile phone 300 captures the first image IM1, the image display system S converts the optical rotation of the polarized light into light transmittance by capturing the image, thereby visualizing the second image IM2. The first image IM1 on which the visualized second image IM2 is superimposed can be provided.

  For example, in this image display system S, the liquid crystal display device 100 displays the image indicating the advertisement information shown in FIG. 2A as the first image IM1, and the image of the predetermined marker shown in FIG.

Specific information can be provided.

  In the present embodiment, since the second image IM2 is clearly visualized on the mobile phone 300, the contrast ratio between the portion of the first image IM1 on which the second image IM2 is superimposed and the second image is large. As described above, the first image data and the second image data are used. For example, it is optimal that the portion of the first image IM1 on which the second image IM2 is superimposed is displayed in white and the second image IM2 is displayed in black. However, the present invention is not limited to this as long as the first image and the second image can be clearly recognized.

A position in the area of the area (hereinafter referred to as “visual area”) A is called “first visual position (P1)”, and the liquid crystal panel 200 is visually viewed through the portable telephone 300 in the area. The position where this can be done is referred to as “second visual position (P2)”. Further, the front-rear positional relationship between the first visual position P1 and the second visual position P2 is not particularly a problem, and any position of the first visual position P1 can be used as long as the liquid crystal panel 200 can be viewed via the mobile phone 300. Even before (the second visual position P2 is closer to the liquid crystal panel 200 than the first visual position P1) or after the first visual position P1 (the first visual position P1 is more liquid crystal panel than the second visual position P2). 200).

[Liquid Crystal Display]
Next, the liquid crystal display device 100 of this embodiment will be described with reference to FIG.

And have. In the liquid crystal display device 100, the irradiation light emitted from the illumination unit 120 is polarized by a polarizing filter provided on the liquid crystal display panel 110, and externally via a personal computer (hereinafter also referred to as “PC”) 130. Based on the input image data (hereinafter referred to as “first image data”), the transmittance of the polarized light (hereinafter referred to as “first polarized light”) is controlled for each pixel, and the first The image IM1 is displayed on the liquid crystal display panel 110 (that is, the image display area 10).

[LCD panel]
Next, the configuration of the liquid crystal panel 200 of this embodiment and the operation of each part will be described in detail with reference to FIGS. 1 and 3 described above. FIG. 3 is a diagram illustrating an example of polarization directions of the first polarized light and the second polarized light (first polarized light in the latent image forming region 21) in the present embodiment.

  The liquid crystal panel 200 is formed on the front surface of the liquid crystal display device 100 and between the liquid crystal display device 100 and the first visual position P1, and emits the first polarized light that forms the first image IM1 displayed on the liquid crystal display device 100. While transmitting, it has a configuration for transmissive display on the front surface (ie, the surface opposite to the surface facing the liquid crystal display device 100). The liquid crystal panel 200 includes a plurality of pixels (pixels), and displays an image that is equal to or greater than the image display area 10 of the liquid crystal display device 100 for displaying the first image IM1 with the transmitted first polarized light. A region 20 and a latent image forming region 21 for forming the second image IM2 as a latent image on a transmission surface of the first polarized light, which is a part of the image display region 20, are provided. For example, as described above, the liquid crystal panel 200 forms a latent image in the left corner of the image display area 20 so that the second image IM2 shown in FIG. 2B is superimposed and displayed as shown in FIG. Region 21.

  Specifically, the liquid crystal panel 200 drives the panel unit 210 with a panel unit 210 that receives the first polarized light and displays the first image IM1 and transmits the second image IM2 as a latent image. Drive control unit 220.

  The panel unit 210 includes a pair of glass substrates (hereinafter referred to as “first glass substrate” and “second glass substrate”) 211 and 212 and a pair of transparent electrodes (hereinafter referred to as “second glass electrodes”). Also referred to as “first transparent electrode” and “second transparent electrode”) 213, 214 and a pair of alignment layers sandwiched between the pair of transparent electrodes (hereinafter referred to as “first alignment layer” and “second alignment”). Also referred to as a “layer”) 215, 216 and a liquid crystal layer 217 sandwiched between a pair of alignment layers.

  In particular, the liquid crystal layer 217 includes liquid crystal molecules that are twisted and aligned at a predetermined angle (specifically, 90 degrees) between the first alignment layer 215 and the second alignment layer 216. The liquid crystal layer 217, for the first polarized light that passes through the region other than the latent image forming region 21, is displayed on the liquid crystal display device 100 along the liquid crystal molecules that are twisted and aligned. While maintaining the display state, the optical rotation is made to be 90 degrees. On the other hand, the liquid crystal layer 217 is a part of the transmission surface of the first polarized light that has entered according to the control of the first transparent electrode and the second transparent electrode based on the second image data input to the drive control unit 220. The optical rotation of the first polarized light transmitted through the latent image forming region 21 is adjusted for each pixel, and the second image IM2 is converted into a latent image by the second polarized light. Specifically, the liquid crystal layer 217 has a first polarized light in a range from 0 degrees (an angle at which the first polarized light enters the liquid crystal layer 217) to 90 degrees in order to make the second image IM2 into a latent image. Thus, the optical rotation is adjusted for each pixel.

  Further, the panel unit 210 has an intersection (that is, an intersection of m rows of data lines (not shown) extending along the column direction and n rows of scanning lines (not shown) extending along the row direction (not shown)). The liquid crystal layer 217 is controlled for each pixel), and the first transparent electrode and the second transparent electrode are controlled based on signals from the scanning line and the data line selected by the second image data input to the drive control unit 220. Thus, the optical rotation of the first polarized light in each pixel is individually controlled.

  Therefore, for example, as shown in FIG. 2 described above, the latent image forming area 21 is formed at the left corner of the image display area 20, and the first image IM1 displayed on the liquid crystal display device 100 is the first image IM1. When the polarized light is polarized in the direction shown in FIG. 3A, the liquid crystal layer 217 passes through the latent image forming area 21 at the left corner of the image display area 20, as shown in FIG. With respect to the first polarized light, the optical rotation of the input first polarized light is set as a reference from 0 degree (optical rotation displayed as black on the mobile phone 300) to a maximum of 90 degrees (first mobile phone 300 has first rotation). The optical rotation is adjusted so that the optical rotation is performed so that the image is displayed as it is (transparent display). In this case, as shown in FIGS. 3A and 3B, the liquid crystal layer 217 has the first alignment layer 215 and the second alignment layer 217 in the first polarized light that passes outside the latent image forming region 21. By the action of the alignment layer 216, the light is rotated by 90 degrees and transmitted.

  That is, in the present embodiment, in the first polarized light that passes outside the latent image forming region 21, no voltage is applied to the first transparent electrode and the second transparent electrode (that is, the data line and the scanning line). 3), the liquid crystal layer 217 cannot be driven and the liquid crystal is twisted and oriented 90 degrees as shown in FIGS. 3 (a) and 3 (b). The first polarized light is rotated 90 degrees along the molecule. On the other hand, since the second image IM2 is formed into a latent image and visualized at the second visual position P2, the first polarized light that passes through the latent image forming region 21 is input to the drive control unit 220. Since the voltage is applied to the first transparent electrode and the second transparent electrode based on the two image data (that is, the voltage of the first transparent electrode and the second transparent electrode is turned on by the data line and the scanning line), As shown in FIGS. 3A and 3B, the liquid crystal layer 217 is individually driven for each pixel, and the optical rotation is adjusted in the range of 0 to 90 degrees based on the optical rotation of the input first polarized light. It has become so.

  In FIG. 3B, the second image IM2 is a simple image formed from a portion having 90 degrees of optical rotation (transmission) and a portion having 0 degrees of optical rotation (blocking). The second image IM2 on which the two-dimensional barcode is formed or the second image IM2 having a gray scale with a predetermined gradation may be formed based on the second image data.

  In addition, since each pixel of the liquid crystal layer 217 is driven and controlled by the first transparent electrode and the second transparent electrode, the latent image forming region 21 that makes the second image IM2 a latent image is fixed to the left corner. As long as it is a region in the liquid crystal layer 217 through which the first polarized light is transmitted, it may be any region, and the contents of an image to be formed into a latent image can be changed.

  As shown in FIG. 1, the drive control unit 220 includes a data line driving circuit 221 that controls the liquid crystal layer 217 corresponding to each pixel via a plurality of data lines, and a pixel that is connected to each pixel via a plurality of scanning lines. A scanning line driving circuit 222 that controls the corresponding liquid crystal layer 217, a memory circuit 223 that temporarily stores second image data to be displayed on the panel unit 210, and a control circuit 224 that controls each unit are provided.

  The data line driving circuit 221 has a plurality of m data lines under the control of the control circuit 224, and selects a corresponding data line based on the input second image data. Further, the scanning line driving circuit 222 has a plurality of n scanning lines under the control of the control circuit 224, and selects the corresponding scanning line based on the input second image data. .

  The control circuit 224 is configured to comprehensively control each of the above parts. In particular, the control circuit 224 converts the second image data into matrix data for controlling the optical rotation in the liquid crystal layer 217 of each pixel, and the data line driving circuit 221 and the scanning based on the converted matrix data. The line driving circuit 222 is controlled. The memory circuit 223 is supplied with the second image data to be displayed on the panel unit 210 from the outside via the control circuit 224, and the supplied second image data is stored therein.

[Portable phone]
