Description
VISUAL DEVICE DEVICE OF ELECTRONIC DEVICE PROVIDED WITH SOLAR CELL
Technical Field The present invention relates to a visual display device for an electronic device comprising a solar cell, for example, an electronic device, such as a watch, an electronic calculator, a radio, a battery charger, and more particularly the watch.
BACKGROUND ART With reference to Figure 26, a conventional example of a clock structure having a solar cell 305 will be described in detail. Figure 26 (a) is a front view showing the inside of a watch case viewed from above, and Figure 26 (b) is a schematic sectional view showing the inside of the watch case. As shown in Figure 26, when light is incident on a solar visual display board 301 of a clock from outside, the light is transmitted through visual display board 301 to reach solar cell 305. Then the solar cell 305 is such a mechanism, that the optical energy is converted into electrical energy, which is charged into a battery or capacitor referred to as a secondary battery that is provided in a module 307, and can store electricity, and in a simultaneous manner, the The module 307 is driven in such a way that a minute hand 301 and an hour hand 309 are moved which are fixed to the central axis 308. In this case, the solar visual display board 301 is placed between the minute hand 310 and the hour hand 309 and solar cell 305. Furthermore, the module 307 indicates a pulse portion in the clock. In recent years, the power generation efficiency of the solar cell has been improved, the power consumption of a module has been reduced, and in addition, the performance of a battery has been improved. Consequently, even when the external shape of a solar cell is much smaller than ever, a minute hand and an hour hand can be driven. On the other hand, increasingly greater degree of freedom has been required for the external shape of a watch case, depending on the diversification of the watch design. A half frame 306 is placed on the outside of the solar cell 305 and the module 307, in such a way that the degree of freedom with respect to the design of the external shape of the clock can be improved. As shown in Figures 26 (a) and (b), the solar cell 305 and the module 307 are fixed through the medium frame 306 to an external box, which is not shown. Moreover, the minute hand 310 and the hand of the hours 309 are linked to the central axis 308 extended from the module 307, and are rotated through the driving force applied from the module 307. In addition, the control board visual display 301 is provided to cover the solar cell 305 and the middle frame 306. The middle frame 306 is provided with a hook mechanism in order to fix the module 307 to which the solar cell 305 is fastened, which is not shown . When the module 307 is adjusted in the middle frame 306, the solar cell 305 and the module 307 are fixed to the middle frame 306, and they are accommodated in the outer box, and therefore, they are fixed thereon. The solar cell 305 has two kinds of substrates, i.e. the substrates formed of a glass and a resin. For both, the solar cell itself has a small thickness. In addition, there is a possibility that the formed glass substrate may be shattered by a stress, such as a shock during or after assembly. The substrate formed of resin could be deformed by a tension thereof during bonding. For a method of attaching to the watch case, therefore, the solar cell 305 and the middle frame 306 are not fixed, but the module 307 and the middle frame 306 are fixed. In the case of the substrate formed of resin, it is it can provide a metal plate on the underside of solar cell 305, in order to improve the reliability of rigidity and electrical connection.
In addition, in the case where the solar display board 301 comes into contact with the solar cell 305, the power generation efficiency of the solar cell 305 could be reduced due to a defect or the like. Accordingly, the average frame 306 also has the function of preventing the reduction of power generation. When the solar visual display board 301 is superimposed on the solar cell 305, the middle frame 306 protrudes slightly upwards from the upper face of the solar cell 305, such that the middle frame 306 comes into contact with the deployment board. visual solar 301 sooner than the solar cell 305. Furthermore, in the case in which the module 307 having the solar cell 305 fixed thereto is incorporated, in the average frame 306, the incorporation can be easily carried out, and productivity can be improved if the external shape of solar cell 305 is coincident with that of module 307, as shown. As described above in detail, the middle frame in the clock parts is a member that has an important role. As shown in Figure 26 (a), a limit line
303 between the solar cell 305 and the middle frame 306 normally requires a tolerance for the watch assembly work, and the tolerance is seen black through the solar visual display board 301. Moreover, a material of plastic for the medium frame 306 in consideration of ease of molding, cost, shock absorption, and the like, and the medium frame 306 is manufactured by injection molding to correspond to the different outer boxes. Accordingly, a gate track 304 is formed on the upper face of the middle frame 306 due to injection molding, and the gate track 304 is also seen through the solar visual display board 301. Furthermore, in the case where the solar cell is divided into some elements to maintain a previously determined voltage and current, the refractive index of the light is varied depending on the difference in material between a portion of the cell and a portion of dividing line, and it is also seen a dividing line of the solar cell element 302 through the solar visual display board 301. According to the knowledge of the present inventors, this phenomenon occurs notoriously when the solar visual display board 301 is black or blue. Figure 26 shows an example where the dividing line 302 of the solar cell element has a cross shape, and the boundary line 303 between the solar cell 305 and the middle frame 306 has the shape of a black ring over the boundary between a portion of sloping line and a dotted portion. To know a technique for viewing this solar cell element divider line with difficulty, a method has been conventionally proposed to be known from Japanese Patent Publication Number Hei 5-38464. In Japanese Patent Publication Number Hei 5-38464, only one color diffusion board is provided between the solar visual display board 301 and the solar cell 305. However, the diffusion board has the function of diffusing the light. Accordingly, the boundary line 303 between the solar cell 305 and the middle frame, the gate track 304 generated by injection molding the middle frame, and further, the dividing line 302 of the solar cell element, are seen with difficulty. As a result, they are necessarily white so that the tone of the solar display panel 301 provided above is affected. According to an experiment performed by the present inventors, if only the color diffusion board is provided between the solar visual display board 301 and the solar cell 305, the black solar visual display board looks gray, which is not preferable with respect to the design. Moreover, a white solar visual display board has diffusion effects by itself. Therefore, even when the diffusion board is not used, the phenomenon that the dividing line 303 between the solar cell 305 and the medium frame 306, the gate track 304 generated by injection molding of the medium frame 306, and the dividing line of the solar cell element 302 is seen through the solar visual display board 301. Accordingly, it is not necessary to provide the diffusion board of Japanese Patent Publication Number Hei 5-38464. Normally different designs are given through the solar visual display board 301. If there is a phenomenon that the boundary line 303, the gate track 304 and the dividing line of the solar cell element 302 are seen as described above, it is affected adversely the quality of the design of a watch. More specifically, in this case, a decoration or similar to a part of the solar visual display board 301 or its entire surface should be given, in order to hide the aforementioned phenomenon. Accordingly, the design for the solar visual display board 301 is restricted, so that a high quality feel for a watch is eliminated. In the three phenomena that adversely affect the quality of the design, as described above, the dividing line of the solar cell element 302 can be considerably improved by giving a protective coating formed of an epoxy resin having Si02 particles distributed thereon. the entire surface of the solar cell 305. Moreover, there is a possibility that the gate track 304 generated during the injection molding of the middle frame 306 is also improved by changing the position of the gate. However, the limit line 303 between the solar cell 305 and the middle frame 306, that is, the tolerance for the clock assembly work can not be avoided, and is the most damaging, and measures are taken with difficulty. In the experiment carried out by the present inventors, the colors of the solar black and blue solar display boards are made to be deeper, and a high quality feeling can be obtained for the articles by deeper colors, and, in addition, it is possible to eliminate the drawback that observation occurs through the solar visual display board described above. However, the transmitted light does not completely reach the solar cell itself, in such a way that the power generation efficiency is reduced, and the operation of the clock is stopped. Moreover, when the tone of the middle frame is adapted to that of the solar cell, it is possible to eliminate the drawback of observation being caused through the solar visual display board described above. However, the boundary line between the solar cell and the middle frame is seen, so that this drawback can not be completely eliminated. In addition, when thinly applying a white paint to the side of the solar cell of the blue solar visual display board having a blue resin therein, it is possible to eliminate the phenomenon that the boundary line 303 between the solar cell 305 and the frame 306, the gate track 304 generated by injection molding of the middle frame 306, and further the dividing line of the solar cell element 302, are seen through the solar visual display board 301. However, the color depth of the The solar visual display board 301 is removed by the diffusion function of the white paint, in such a way that the high quality feeling disappears for the individual solar visual display board. In other words, the formation of a diffusion layer can not obtain sufficient effects. On a visual display board, such as a watch face, different colors and patterns are applied to the surface or to the back of the visual display board, or to both, in order to give a feeling of high quality (value added) in some cases. The coloring is done by printing the surface of the material that is going to be the visual display board, or manufacturing the visual display board from a resin containing a pigment, for example. Moreover, in the case of a metal visual display board, the pattern is formed on its surface by etching, a mat processing, or the like. In the case of a visual display board formed of resin, a pattern is formed by injection molding the resin in a mold having the pattern formed therein. However, the aforementioned visual display boards are not satisfactory with respect to the depth of a pattern, a three-dimensional effect, and the like.
In consideration of these circumstances, it is an object of the present invention to provide a visual display device for an electronic device comprising a solar cell and a middle frame, for fixing the solar cell and a module to an external box where it can be made that the necessary light and sufficient reach to the solar cell, that a high quality sensation can be given, and in addition, that it is possible to increase the variation in the design, where a decorative property is greater, and where the depth of the pattern and the three-dimensional effect are excellent.
Disclosure of the Invention The present invention has been made to solve the problems of the conventional technique described above, and to achieve the aforementioned object, and provides a visual display device for an electronic device, which comprises a solar cell, wherein a circular polarization plate is provided to transmit light on the front side of the solar cell in a direction of incidence of light. In a circular polarization plate constituted by a linear polarization plate and a phase difference plate, the linear polarization plate and the phase difference plate are provided in this order in a direction of incidence of light. As a result, the light reflected by a surface of the solar cell can be blocked, and the boundary line between the solar cell and the middle frame can not be seen, the gate track generated by injection molding of the middle frame, and the line divider of the solar cell element, through the circular polarization plate. As a result, the tone of the solar visual display board is not affected. Moreover, it is not necessary to hide the three drawbacks through a pattern in the form of strips or the like. Therefore, the variation in the design of the solar visual display board can be increased. In addition, a solar visual display board having a deep color can be used, so that a high-quality feel in the articles can be obtained visually. By directly giving the mark, such as a numeral, to the linear polarization plate by means of printing or the like, the function of the solar visual display board can also be given to the linear polarization plate itself. Moreover, the present invention is characterized in that the surface of the circular polarization plate is provided with a solar visual display board constituted by a resin substrate having a pattern, an inorganic substrate having a pattern or a thin film er decorative or a combination thereof.

BEST MODE FOR CARRYING OUT THE INVENTION The embodiments of the present invention will be described below. First of all, the function of a circular polarization plate will be described with reference to Figures 27 to 29.
The circular polarization plate is usually made by attaching a linear polarization plate 111 formed from a film material to a 1/4"plate, 112 formed of a film material with an adhesive layer. As a matter of course, if the circular polarization plate has the circular polarization function, other structures and members can be used. Moreover, the linear polarization plate can have a structure such that a thin film of iodine-absorbing polyvinyl alcohol is spread in one direction, and molecules are configured in parallel, and walled with acetylbutylcellulose. In addition, a lens or group of lenses can be used to collect light in one direction. Because the mirror reflection can be suppressed, the linear polarization plate is used to improve contrast or reduce eye fatigue. The linear polarization plate 111 has a type of absorption or a type of reflection. An absorption axis or a reflex axis is orthogonally present to the transmission axis. When natural light for oscillation in all directions is incident on the linear polarization plate 111, as shown in Figure 27, only light is transmitted in the same oscillatory direction as the transmission axis. In the type of absorption, the incident light on the linear polarization plate 111 is absorbed in the polarization plate. Moreover, the type of reflection has the function of reflecting the incident light on the linear polarization plate 111 from a surface of the polarization plate. The embodiments according to the present invention will be described using an absorption type linear polarization plate and a l / 4? as the linear polarization plate and the phase difference plate if a special description is not given. The transmitted light polarized in one direction is incident at an angle of 45 ° with respect to the axis of delay of the phase difference plate. In this case, the phase difference plate represents the plate of l / 4 ?, 112, and divides the incident light at 45 ° in the x and y directions for greater convenience, and considers both maximum amplitudes as 1, as shown in Figure 28. An abscissa axis indicates an angle, and an ordinate indicates an amplitude, and the relationship between the wavelength and the phase is such that a wavelength is 360 ° (?). If the axis of delay of the phase difference plate is set in the direction y, the presence of the phase difference plate causes the light transmitted through the phase difference plate to be delayed by l / 4? phase only in the y direction. Suppose the case where the light advances by 3/4 wavelength through the plate of l / 4 ?, 112. The light does not delay in the x direction, and is delayed by l / 4? in the direction y, as shown in solid line from a waveform shown in the chain line of individual points. Accordingly, a point A (-1, 0) is obtained in Figures 28 and 29. Moreover, when the light further advances by l / 4 ?, a point B (0, 1) is obtained in Figures 28 and 29 in the same way. When the time passes additionally as shown in Figure 29, the light advances from point C (1, 0) to point D (0, -1) in the same way. Accordingly, the light passing through the plate of l / 4 ?, 112, is converted from linear polarized light to circular polarized light, as shown in Figures 27 and 29. The light thus circularly polarized is reflected through the surfaces of an average frame 113 and solar cell 114, and is incident on the plate of 1/4 ?, 112, again inversely to the direction of advancement, as shown in Figure 27. In the same manner to the one described above, the light becomes light having a plane of oscillation in a direction perpendicular to the direction of incidence on the plate of l / 4 ?, 112, and the light thus obtained is vertical to the transmission axis of the linear polarization plate 111. Accordingly, the light can not pass through the linear polarization plate 111, such that the reflected light is blocked. The linear polarization plate 111 and the 1/4"plate 112 are combined to form a circular polarization plate. In this case, it has been known that the incident light is reflected by approximately several percentages per boundary surface, if in general boundary surfaces having different refractive indices are present. In the case of air and glass, incident light is reflected by approximately 4 percent. Therefore, it is preferable that the number of limit surfaces be reduced as much as possible. In accordance with the foregoing, it is preferable that the linear polarization plate 111 and the 1/4"plate 112 are stacked in a state of close contact, or bonded with an adhesive or glue. Although the linear polarization plate 111, the plate of l / 4 ?, 112, and the middle frame 113 are square in shape, and the solar cell 114 is circular in Figure 27, other different shapes corresponding to the design can be used.

As shown in Figure 1, a clock having a solar cell comprises a solar cell 13 electrically connected to a module 14, and a minute hand 17 and an hour hand 16 that are fixed to a central axis 15. A circular polarization plate A is provided which includes a linear polarization plate 11 and a plate of l / 4 ?, 12, between the hands 16 and 17 and the solar cell 13. With this structure, the dividing line of the solar cell element of the solar cell 13 can not be seen through the circular polarization plate constituted by the plate. polarization 11 and the plate of l / 4 ?, 112. Moreover, because the reflected light is eliminated, the color of the surface of the linear polarization plate 11 is deepened, in such a way that a High quality feeling in the article. In the present embodiment, the marking of a numeral is directly given to the linear polarization plate 11 by means of printing, to provide the function of a solar visual display board. Moreover, it is desirable that the circular polarization plate A, constituted by the linear polarization plate 11 and the plate of 1/4? 12, have a flat direction positioned by an external box, which is not shown, with respect to the assembly work of a clock. In the following modes, because the effects are not affected, the description of the minute and hour hands will be omitted if there is no special condition. In the same way as in the following embodiments, although the components are shown separated from each other for greater convenience of description in the drawings, they are actually incorporated in a state of close contact, for example, appropriately in a state of adhesion, link and welding with an adhesive, an adhesive or similar.
(Second Modality) As shown in Figure 2, a circular polarization plate A is provided which includes a linear polarization plate 22 and a plate of 1/4? between the solar cell 24 and the solar visual display board 21, which has light transmission. Consequently, the dividing line of the solar cell element of the solar cell 24 can not be seen through the solar visual display board 21, so that the variation in the design of the solar visual display board 21 is increased. , the color of the solar visual display board 21 is deepened, in such a way that a high quality feeling of the articles is obtained. In a work to assemble the watch, first of all, a module 25 is manufactured, and simultaneously the external shapes of the visual display board 21, the solar cell 24, the linear polarization plate 22, and the plate of l / are processed simultaneously. 4? 23, through press molding or the like, and overlap with a structure shown in Figure 2 in an outer box, which is not shown, so that a finished watch is obtained. According to the above, it is desirable that the circular polarization plate constituted by the visual display board 21, the solar cell 24, the linear polarization plate 22, and the plate of 1/4? 23, have the same external forms.
(Third Mode) In the present embodiment, Figure 3 shows the structure of a clock where a module 34 having a solar cell 33 in an external box 39 is fixed through an intermediate frame 35. A polarization plate is provided. circular A constituted by a linear polarization plate 31 and a plate of l / 4? 32, above the middle frame 35, between the minute hand 37 and the hand of the hours 36, which are fixed to a central axis 38 and to the solar cell 33. Through this structure, the limit line between the solar cell 33 and the middle frame 35, the gate track generated by injection molding of the middle frame 35, and in addition, the dividing line of the solar cell element of the solar cell 33 through the circular polarization plate A constituted by the linear polarization plate 31 and the plate of 1/4? 32. Furthermore, it is desirable that the circular polarization plate A be provided to cover the solar cell 33 and the middle frame 35, as shown. Because the reflected light is removed, the color of the surface of the linear polarization plate 31 is deepened, so that a high quality feel of the articles can be obtained. In the present embodiment, the marking of a numeral is directly given to the linear polarization plate 31 by printing, to provide a function as a solar visual display board. Moreover, the average frame 35 is provided. Accordingly, different external shapes of the watch can be obtained with respect to the design, in the following embodiments, because the effects are not affected, the description of the outer box will be omitted.
(Fourth Mode) Also in the present embodiment, Figure 4 shows the structure of a clock where a module 45 having a solar cell 44 is fixed through the middle frame 46 in an external box, which is not shown. In the present embodiment, the circular polarization plate A constituted by the linear polarization plate 42 and the plate of 1/4? 43, is provided between the middle frame 46 and the solar visual display board 41. Through this structure, the boundary line between the solar cell 44 and the middle frame 46, the gate track generated by injection molding of the middle frame 46, and in addition, the dividing line of the solar cell element of the solar cell 44, through the visual display board 41, in such a way that the variation in the design of the solar visual display board 41 can be increased. In addition, the color of the solar visual display board 41 is deepened, so that a high quality feeling of the articles can be obtained. Furthermore, an average frame 46 is provided. Accordingly, different external shapes of the clock can be obtained with respect to the design. In the present embodiment, furthermore, a color visual display board including a dye, a pigment and the like, is used for the solar visual display board 41, for example. Accordingly, although the tone has only one black color in the third embodiment, the visual display board may have colors. Therefore, it can be seen that the practical use can be improved in a considerable way with respect to the design. Moreover, it is desirable that the circular polarization plate A constituted by the linear polarization plate 42 and the l / 4"plate, the middle frame 46, and the solar visual display board 41, have the same external shapes with respect to to the assembly work.
(Fifth Mode) Also in the present embodiment, Figure 5 shows the structure of a clock where a module 56 having a solar cell 55 is fixed through an average frame 57, in an external box, which is not shown . In the present embodiment, a circular polarization plate B having a linear polarization plate 52, a plate of l / 4? 53, and a plate of l / 2? 54, stacked. The circular polarization plate B is provided between the middle frame 57 and the solar visual display board 51. With this structure, the same effects can be obtained as those of the fourth mode. It has been known that the provision of the plate of l / 2? 54 can amplify a wavelength region where light can be blocked, and a wide-band type circular polarization plate can be obtained. In the same way as the plate of l / 4 ?, the plate of l / 2? it includes an axis of delay, and has the function of delaying incident light in that direction by l / 2 ?.
(Sixth Modality) As shown in Figure 6, a solar visual display board 61, a linear polarization board, is bonded
62, and a plate of l / 4? 63, through an adhesive layer 68, and then pressurized and molded. Accordingly, an integral visual solar display board of circular polarization plate C is manufactured. The integral visual solar display board of circular polarization plate C is provided above a solar cell 64 having a diffusion layer 67 preformed on its upper surface. Also in this case, in a similar manner, the boundary line between the solar cell 64 and the middle frame 66, the gate track generated by injection molding of the middle frame 66, and in addition, the dividing line of the element can not be seen. of the solar cell of the solar cell 64, through the solar visual display board 61. As a result, the variation in the design of the visual display board 61 can be increased. In addition, the color of the visual display board is deepened Solar 61, in such a way that you can get a high quality feeling of the items. Even more, the middle frame 66 is provided. Accordingly, different external shapes of the watch can be obtained with respect to the design. In general, it has been known that the incident light is reflected by approximately several percentages for each of the boundary surfaces having different refractive indices. In the case of air and glass, incident light is reflected by approximately 4 percent. Therefore, it is preferable that the number of boundary surfaces be reduced as much as possible. By applying to the present embodiment, when two film materials are inserted, i.e., the linear polarization plate 62 and the plate of 1/4? 63 between the solar visual display board 61 and the solar cell 64 having the diffusion layer 67 formed thereon, the number of boundary surfaces is increased through the insertion of the films, in such a way that the light is reduced transmitted to the solar cell 64. However, when the solar visual display board 61 and the linear polarization plate 62, and the linear polarization plate 62 and the l / 4? 63, through an adhesive layer 68, respectively, as in the present embodiment, the number of boundary surfaces is reduced from 7 to 3. As a result, the light transmitted to the solar cell 64 can be further improved, and it can be improved plus the power generation efficiency, comparing with the case where the adhesive layer 68 is not provided. In order to perform the accommodation in an external box, which is not shown, moreover, a processing of the external shape, and also a perforation processing is required to penetrate with an external arrow, which is not shown. If three layers are bonded by adhesive layers, the processing is done only once, in such a way that the steps can be simplified, and the cost can be reduced. Comparing with the box where the three layers are processed separately, in addition, it is possible to prevent movement when the three layers are linked. As a result, the quality of the design can also be improved. In addition, referring to a work to assemble a clock in accordance with the present embodiment, the diffusion layer 67 is first formed on the surface of the solar cell 64, is linked to a module 65, and then fits in the middle frame 66. At the same time, the solar visual display board 61, the linear polarization board 62, and the board of l / 4? 63 through the adhesive layer 68, and then the processing of the external shape and the perforation are carried out by means of a press or the like. Subsequently, as shown, they are superimposed on an external box, which is not shown. For 1? So much, you get a finished clock. In the present embodiment, because the solar visual display board 61, the linear polarization plate 62, and the plate of l / 4? 63 are bonded through the adhesive layer 68, can be treated as a member. Consequently, the work to assemble a clock can be performed more easily in these modalities.
(Seventh Modality) As shown in Figure 7, a solar visual display board 71, a linear polarization plate 72, a plate of l / 4? 73, a solar cell 74 and an intermediate frame 76, as shown, and are bonded with an adhesive layer 77. Also in this case, in the same manner as in the sixth embodiment, the boundary line between the cell can not be seen. solar 74 and the middle frame 76, the gate track generated by injection molding the middle frame 76, and further, the dividing line of the solar cell element of the solar cell 74, through the solar visual display board 71, of such that the variation in the design of the solar visual display board 71 can be increased. In addition, the color of the solar visual display board 71 is deepened, so that the high quality feeling of the articles can be obtained . Moreover, the average frame 76 is provided. Accordingly, different external shapes of the clock can be obtained with respect to the design. Also in the present embodiment, in the same manner as in the sixth embodiment, the number of limit surfaces provided between the visual display board 71 and the air is one, and transmission may be further improved than in the sixth mode, and You can also improve the power generation efficiency.
(Eighth Mode) In the present embodiment, the solar cell 83 is larger than the external shape of the module 84, and the external shape of the middle frame 85 for fixing the module 84 to an external box, which is not shown, is equal to that of the solar cell 83. In the present embodiment, the solar cell 83 completely covers the boundary line between the middle frame 85 and the module
84 and a gate track generated by injection molding of the mid frame 85. Therefore, the quality of the visual display is not reduced. By inserting a linear polarization plate 81 and a plate of 1/4", a dividing line of the solar cell element of the solar cell 83 can be prevented.
(Ninth Mode) The present embodiment provides a clock structure where a solar cell 94 and a module 95 are fixed through an intermediate frame 96 to an external box, which is not shown. Then a circular polarization plate A consisting of a linear polarization plate 92 and a plate of 1/4? 93, above the middle frame 96. In addition, a liquid crystal display panel 91 is provided above them. The liquid crystal display panel 91, which has an external shape smaller than that of the solar cell 94, is provided above the circular polarization plate A.
Accordingly, the light transmitted through the linear polarization plate 92 and the plate of 1/4? 93 reaches the solar cell 94, and energy is supplied to the panel of the liquid crystal display, to display the time by the electromotive force of the solar cell 94. Also in the present embodiment, in the same way as in the seventh embodiment , the boundary line between the solar cell 94 and the middle frame 96, the gate track generated by injection molding of the middle frame 96, and in addition, the dividing line of the solar cell element of the solar cell 94, can not be seen, in such a way that the variation in the design can be increased, and a feeling of high quality of the articles can be obtained. In the present embodiment, the liquid crystal display panel displays the time of 12 o'clock in the afternoon.
(Tenth Modality) A linear polarization plate has a type of absorption and a type of reflection. In the present embodiment, a reflex-type linear polarization plate having a reflex axis orthogonal to the transmission axis is used. In the event that a circular polarization plate is constituted by the reflective-type linear polarization plate and a plate of l / 4 ?, and inserted between a solar visual display board and a solar cell, a mirror-type linear polarization plate 42 'is used as a linear polarization plate 42 as in other embodiments, for example, as shown in Figure 10. In this case, the boundary line between the solar cell 44 and the middle frame 46, the gate track generated by injection molding the middle frame 46, and in addition, the dividing line of the solar cell element of the solar cell 44, through the solar visual display board 41. As a result, the variation in the design of the solar visual display board 41 can be increased in the same manner as in the fourth mode. In the case of a blue solar visual display board, the brightness is reduced and the blue color of the solar visual display board is made deeper by using the absorption-type linear polarization plate, and the blue color is reproduced of the solar visual display board faithfully using the reflective type linear polarization plate. Furthermore, in the case of a black solar visual display board, the brightness is also reduced, and a high quality feeling can be obtained by using the absorption-type linear polarization plate, and the brightness of the black color of the solar visual display board to approximate a gray color by using the reflective type linear polarization plate. As described above, the color of the solar visual display board is changed in a deeper direction by the use of the absorption-type linear polarization plate, and a high-quality feeling can be obtained visually regardless of the color of the board of solar visual display. The type of absorption is different from the type of reflection in that the oscillation in a direction perpendicular to the transmission axis of the linear polarization plate is absorbed in the linear polarization plate, or is reflected from the surface of the linear polarization plate. Therefore, they perform the same actions for transmitted light, and have the same functions as circular polarization plates.
(Eleventh Modality) As shown in Figure 11, a diffusion layer 47 is formed between the solar display panel 41 and the linear polarization plate 42 in the structure of Figure 4. Through this structure, they can not be seen the boundary line between the solar cell 44 and the middle frame 46, the gate track generated by injection molding the middle frame 46, and further, the dividing line of the solar cell element of the solar cell 44, more than those of the fourth modality, in such a way that the variation in the design of the solar visual display board can be increased 41.
In addition, the color of the visual display board 41 becomes deeper, a high quality feeling of the articles can be obtained. Moreover, the middle frame is provided. Accordingly, different external forms of a clock can be obtained with respect to the design. In the present embodiment, when the solar visual display board 41 is subjected to injection molding, the concave-convex shapes previously formed in a mold are transferred to the surface opposite the linear polarization plate 42 of the solar visual display board 41 , in such a way that a diffusion layer is formed. As described in the Background of the Invention, the simple formation of the diffusion layer is not sufficient.
By using a circular polarization plate in this manner, the aforementioned effects can be produced.
(Twelfth Modality) As shown in Figure 12, a diffusion layer 48 is formed between the linear polarization plate 42 and the l / 4? 43 in the structure of Figure 4. Accordingly, the boundary line between the solar cell 44 and the middle frame 46, the gate track generated by injection molding of the middle frame 46, and in addition, the dividing line can not be seen. of the solar cell element of the solar cell 44, more than those of the fourth embodiment, in such a way that the variation in the design of the solar visual display board 41 can be further increased. Additionally, the color of the board becomes deeper of solar visual display 41, and you can get a feeling of high quality articles. Moreover, an average framework is provided. Accordingly, different external forms of a clock can be obtained with respect to the design. In the present embodiment, oxide particles are dispersed in an adhesive layer between the linear polarization plate 42 and the 1/4"plate. 43, in such a way that the diffusion layer is formed.
(Thirteenth Mode) As shown in Figure 13, a clock structure 100 according to the present embodiment is set, a solar cell 102 and a module 104, through an intermediate frame 106, to an external box, which it is not shown. A circular polarization plate A consisting of a linear polarization plate 101 and a plate of 1/4"is provided. 103 above. medium frame 106. In addition, a solar visual display board 108 is provided above them. As shown in Figure 14, the solar visual display board 108 is constituted by a resin substrate body 110, and a portion of pattern 112 formed on its upper surface. It is preferable that the resin substrate 110 is formed of a thermoplastic resin, and in addition, a resin selected from the group consisting of polyvinyl chloride, an acrylic resin and polycarbonate. In the present invention, it is particularly preferable that acrylic resin or polycarbonate be used. The thickness of the resin substrate 110 is preferably about 50 to 500 microns, and more preferably about 80 to 200 microns. The resin substrate 11 can be transparent or colored and translucent. A pattern is given to the resin substrate 110 by an injection molding method, for the injection molding of a resin in a mold having a pattern formed therein (which will be referred to hereinbelow as a "pattern mold"). "); a pattern transfer method for transferring a pattern onto a resin substrate through a thermal press using the pattern mold; or a method of machining using recording, rubbing or the like. In the present invention, in particular, the pattern transfer method is preferably employed. As a method of patterning the resin substrate 110, the pattern transfer method will be described below.
As shown in Figures 15 (A) to 15 (C), the pattern transfer method comprises the steps of making an electrical mold 120 having a pattern surface, and thermally pressing a patterned surface 122 molded into the mold electrical 120 against the resin substrate 110. When the electrical mold 120 having the pattern surface is to be manufactured, a surface pattern of an article 124 having a pattern is first molded through an electrical molding method. More specifically, article 124 having the pattern is subjected to electroforming. In the case where article 124 has no conductivity, a metallic film 126 is formed on the surface of article 124 to give conductivity to article 124. The examples of article 124 having the pattern include cloth, paper, slit, grain, pyroxene , leaf, petal, shell, leather, artificial substances that have different fine patterns (an artificial leather, engraving, setting) and the like. It is preferable to use cloth, paper, slit, grain, pyroxene, sheet, engraving and setting. As shown in Figure 15 (A), a pattern is formed on the surface of article 124 (the concavo-convex portions on the surface in Figure 15 (A) .In Figure 2, the back face of the article is omitted. 124. In order to give conductivity to the surface of article 124, first the surface of article 124 is cleaned, and then a metal film 126 is formed on the surface of article 124. Metal film 126 is formed by vacuum evaporation, Ionic plating, sputtering, non-electrolytic plating, silver mirror reaction or the like, for example, Although metallic film 126 is formed of a metal, such as silver or gold, or its alloys, and its thickness is not particularly restricted, it is a thickness of about 1 to 30 microns, preferably about 1 to 10 microns, is suitable In the case where article 124 has conductivity, as described above, it is not necessary to form the film metal layer 126. Next, the surface of the metal film 126 is subjected to removal, if necessary. When article 124 has conductivity, the surface of article 124 is directly subjected to removal. The removal can be done by injection of selenious acid. When the removal is performed, the electric mold 120 can be easily removed. As shown in Figure 15 (B), a metal is then deposited on the surface of article 124, or on the surface of metal film 126, through of electric molding (electroforming) to form the electric mold 120. As a material of the electric mold 120, a metal, such as nickel, copper or iron, or its alloys is preferably used. The thickness of the electric mold 120 is 100 to 300 microns, preferably 100 to 250 microns, and more preferably 100 to 200 microns. If the thickness of the electric mold 120 is established in this range, the resin substrate 110 is not deformed, and heat transfer can be performed well during thermal compression. The conditions of the electric molding are not particularly restricted, but are appropriately selected from conventional electric molding (plywood) conditions. The electric molding conditions will be briefly described to obtain the electric mold 120 having a thickness of 200 microns, by using a nickel metal. However, conditions should not be restricted by this condition. As a pretreatment, the surface of the article 124 having a pattern or the metallic film 126 is subjected to treatments of electrolytic degreasing, washing, neutralization with acid, washing, removal (potassium dichromate) and washing. Then electroforming is performed at 265 AH
(IA / dm2) at a liquid temperature of 50 ° C, by using a nickel plating bath (450 grams / liter of nickel sulphamate, 40 grams / liter of boric acid). Accordingly, the electric mold 120 having a thickness of 200 microns is obtained. As shown in Figure 15 (C), then the electric mold 120 is removed from the surface of the article 124, or from the surface of the metal film 126. Accordingly, the electric mold 120 having a pattern surface is obtained. molded The electric mold 120 thus obtained is cut corresponding to the shape of a visual display board as intended, if necessary. As shown in Figure 16, the molded pattern is subsequently transferred to the resin substrate 110. In order to transfer the pattern to the resin substrate 110, the surface of the molded pattern of the electrical mold 120 is opposite to the queen substrate 110, and thermally compressed between a pair of upper and lower thermal presses 130 and 132. Although the conditions of the thermal press are varied depending on the material and the thickness of the resin substrate 110, a temperature of the thermal press in the vicinity is generally established. of the melting temperature of a resin, specifically is suitable from about 90 ° C to 180 ° C. In particular, it is preferable that the temperature on the side of the electric mold be set from 120 ° C to 140 ° C, and that a resin substrate temperature of about 40 ° C to 80 ° C be established in a thermal press machine .
Suitably the pressure of the thermal press is set at from about 20 to 100 ilograms / cm2. Moreover, it is preferable that the time required for the thermal press be established in about 10 to 180 seconds. Before the thermal compression of the resin substrate
110, a pre-heating is performed, in such a way that the time required for thermal compression can be reduced, and productivity can be improved. It is preferable that the preheat temperature is set at about 40 ° C to 80 ° C. If this pre-heating treatment is carried out, the time required for thermal compression can be reduced to approximately 10 to 30 seconds. Moreover, the electric mold 120 can be bonded to a thermal press head during thermal compression.
Accordingly, the resin substrate 110 and the electrical mold 120 can be easily removed from each other after thermal compression, so that productivity can be improved. Through thermal compression, the molded pattern
122 of the electric mold 120 is transferred to the resin substrate 110, and the electric mold 120 is removed. Accordingly, a resin substrate 110 having a pattern can be obtained. In addition, it is also possible to manufacture a transparent resin film having a pattern on both surfaces, thermally compressing the pattern surface of the electrical mold 120 against both surfaces of the resin substrate 110 at the same time or in a successive manner. In the case where thermal compression is to be performed on both surfaces at the same time, it is preferable that the electrical mold 120 be attached to the upper and lower heads of the thermal press. In the case where the thermal compression is going to be carried out in a successive manner on both surfaces, moreover, it is preferable that the thermal press works on one of the surfaces, then the resin substrate 110 is turned over, and the thermal press works on the other surface. The resin substrate 110 having a pattern is manufactured in an independent manner, one by one, in the method of manufacturing the resin substrate 110 having a pattern described above. However, it is also possible to obtain a resin substrate 110 having a pattern by producing the electric mold 120 having a plurality of patterns, thermally compressing the electric mold 120 against a plastic film, producing the resin substrate 110 having a plurality of pattern portions, and cutting the shape of a visual display board for each pattern.

Alternatively, the resin substrate 110 is integrated via bonding using an adhesive, bond using an adhesive, film bond, fusion bond, high frequency bond or the like, for example. A pattern can be transferred to the resin substrate 110 before or after the bonding of the resin substrate 110 and the circular polarization plate A. After that the molded pattern of the electrical mold 120 is transferred in this way to the resin substrate 100 by the thermal press, the transfer of the pattern to the resin substrate 110 and the integration with the circular polarization plate A can also be performed simultaneously by using the thermal press, as shown in Figure 17, instead of stacking the substrate. resin 110 on the upper surface of the circular polarization plate A constituted by the linear polarization plate 101 and the plate of 1/4? 103, or integrating the resin substrate 110 with it.

Figure 17, the circular polarization plate A constituted by the linear polarization plate 101 and the plate of l / 4? 103, the resin substrate 110 and the electrical mold 120, are provided between the pair of upper and lower thermal presses 130 and 132 in order. Then, the pattern 122 of the electric mold 120 is transferred to the upper surface of the resin substrate 110 by thermal compression at one time, and the resin substrate 110 is welded and integrated with the circular polarization plate A by heating the thermal press. In this case, it is desirable that an adhesive be interposed between the resin substrate 110 and the circular polarization plate A, because the integration can be easily performed, which is not shown. By this method, the pattern 122 of the electric mold 120 is transferred to the upper surface of the resin substrate 110 through the thermal compression at one time, and the resin substrate 110 is integrated with the circular polarization plate A by means of the heating of the thermal press.
