In the process of switching the first use state to the second use state, the input device 21 generates a first input signal in response to the operation of the user, and the processing control unit 22 disables the first light source 101 and simultaneously enables the second light source 102 according to the first input signal, so that the second light source 102 emits a second light beam L2 incident on the refractive structure layer 13 and forms a second included angle θ 2' with the reference plane P. In the process of switching the second using state to the first using state, the input device 21 generates a second input signal in response to the operation of the user, and the processing control unit 22 disables the second light source 102 and simultaneously enables the first light source 101 according to the second input signal, so that the first light source 101 emits a first light beam L1 incident on the refractive structure layer 13 and forms a first included angle θ 1' with the reference plane P.
It should be noted that, in the embodiment, the number of light sources is two, but the invention is not limited to the number of light sources, and in other embodiments, the number of light sources may be increased to more than two according to the actual requirement, for example, a third light source is additionally provided in addition to the first light source 101 and the second light source 102 shown in fig. 4 to 6, and the configuration position of the added third light source is different from the third position of the first light source 101 and the second light source 102, when the number of light sources is increased to three, an image display layer having three pattern sections is simultaneously matched, that is, a third pattern section with different patterns is additionally provided in addition to the first pattern section 121 and the second pattern section 122 shown in fig. 4 and 5, when a third light beam emitted by the third light source at the third position is incident on the refractive structure layer 13 and forms a third included angle with the reference plane P, since the third included angle is different from the first included angle θ 1 'and the second included angle θ 2' shown in fig. 4 and 5, the incident third light beam is refracted by the refractive structure layer 13 and then guided to the third pattern section of the image display layer, so that the image display layer displays a third image corresponding to the third pattern section.
Furthermore, it is emphasized that in embodiments where the image display device has a plurality of light sources, the number of pattern sections of the image display layer may be larger than the number of light source configurations, provided that in case one of the light sources is movable, the number of pattern sections of the image display layer does not necessarily correspond to the number of light sources.
In summary, in the image display device according to the embodiment of the invention, the angle at which the light beam emitted by the light source enters the refraction structure layer (that is, the included angle between the light beam and the reference plane) is changed by adjusting the relative position between the light source and the refraction structure layer, and the refraction structure layer refracts the light beam entering at different angles and guides the light beam to different pattern sections on the image display layer, so that the image display layer displays different images. In addition, the relative position between the light source and the refractive structure layer is controlled by an input device (such as a touch panel or a key switch) on the electronic equipment to achieve the purpose of displaying different images.
While the invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Furthermore, it is not necessary for any embodiment or claim of the invention to achieve all of the objects or advantages or features disclosed herein. In addition, the abstract and the title of the invention are provided to assist the searching of patent documents and are not intended to limit the claims of the invention. Furthermore, the terms "first," "second," and the like in the description or in the claims are used only for naming elements (elements) or distinguishing different embodiments or ranges, and are not used for limiting the upper limit or the lower limit on the number of elements.
