no. 1 example

[0072] The description of the function of circular polarization has been completed, and the following will refer to figure 1 The first embodiment will be described in detail.

[0073] as figure 1 As shown, a watch with a solar cell includes a solar cell 13 electrically connected to a module 14 , and a minute hand 17 and an hour hand 16 fixed to a central axis 15 . Between the pointers 16 and 17 and the solar cell 13, a circular polarizing plate A including a linear polarizing plate 11 and a 1 / 4λ wave plate 12 is provided.

[0074] With this structure, the solar cell element dividing line of the solar cell 13 cannot be seen through the circular polarizing plate composed of the linear polarizing plate 11 and the 1 / 4λ wave plate 12 . In addition, since reflected light is eliminated, the color of the surface of the linear polarizing plate 11 is deepened, so that a high-quality feeling of the article can be obtained.

[0075] In this embodiment, marks such as numbers are direc...

[0079] as figure 2 As shown, a circular polarizing plate A including a linear polarizing plate 22 and a 1 / 4 lambda wave plate 23 is arranged between the solar cell 24 and the solar display panel 21 with light transmittance.

[0080] Therefore, the dividing line of the solar cell element of the solar cell 24 cannot be seen through the solar display panel 21 , thereby increasing the variation in the design of the solar display panel 21 . In addition, the color of the solar display panel 21 is darkened so that a high-quality feeling of the item can be obtained.

[0081] In the work of assembling the watch, at first, the module 25 is prepared, and the shapes of the solar display panel 21, the solar cell 24, the linear polarizing plate 22, and the 1 / 4λ wave plate 23 are simultaneously processed by die-casting or the like, so as to figure 2 The structure shown superimposes them in a case (not shown) to obtain the finished watch. Therefore, preferably, the circular polarizing pla...

[0083] In this example, image 3 The structure of a watch is shown, in which a module 34 with a solar cell 33 is fixed via an intermediate frame 35 into a case 39 .

[0084] A circular polarizing plate A composed of a linear polarizing plate 31 and a 1 / 4 lambda wave plate 32 is provided on the intermediate frame 35 between the minute hand 37 and the hour hand 36 fixed on the central axis 38 and the solar cell 33 .

[0085] With this structure, the boundary line between the solar cell 33 and the intermediate frame 35, the sprue mark produced by the injection molding of the intermediate frame 35, and also the solar cell element dividing line of the solar cell 33 pass through the line formed by the linear polarizing plates 31 and 1. The circular polarizing plate A composed of the / 4λ wave plate 32 cannot be seen.

[0086] In addition, preferably, the circular polarizing plate A should be arranged to cover the solar cell 33 and the intermediate frame 35, as shown in the figure. ...

Abstract

In a display device for an electronic apparatus, a circular polarizing plate constituted by a linear polarizing plate 42 and a 1/4 lambda plate 43 is provided between a solar display board 41 and a middle frame 46 for fixing a module 45 having a solar cell 44 to an outer case. As a result, a boundary line between the middle frame 46 and the solar cell 44, a gate track generated through injection molding of the middle frame 46, and furthermore, a solar cell element dividing line of the solar cell 44 cannot be seen. Consequently, a variation in design of the solar display board 41 can be increased. Moreover, the color of the solar display board 41 is deepened so that a feeling of high quality can be obtained as goods, and the provision of the middle frame can provide various external shapes of a watch in respect of the design.

Description

technical field [0001] The present invention generally relates to displays for electronic devices comprising solar cells, for example electronic devices such as watches, electronic calculators, radios, chargers, especially watches. Background technique [0002] refer to Figure 26 , a general example of the structure of a watch including the solar cell 305 will be described in detail. Figure 26 (a) is a front view from above showing the interior of the case, Figure 26 (b) is a sectional view showing the inside of the case. [0003] as Figure 26 As shown, when light is incident on the solar display panel 301 of the watch from the outside, the light passes through the solar display panel 301 and reaches the solar battery 305 . The solar cell 305 is such a mechanism that converts light energy into electrical energy, and the electrical energy is charged into a battery or capacitor (called a secondary battery) disposed in the module 307 and can store el...
