Abstract: A color adjusting method for a color light-emitting element is provided. Firstly, a first white light beam is produced by red, green and blue light-emitting units collaboratively, and a second white light beam is produced by a white light-emitting unit. Then, a second chromaticity value corresponding to the second white light beam is acquired. Then, the red, green and blue light-emitting units are controlled to produce a third white light beam according to the second chromaticity value, and a first adjusting parameter is acquired. Then, the white light-emitting unit is controlled to produce a fourth white light beam according to a third luminance value corresponding to the third white light beam, and a second adjusting parameter is acquired. Then, a gray level adjustment process is performed according to the first and second adjusting parameters.

Abstract: An image displaying device includes a grating plate, a light source module, plural image regions and a support structure. The grating plate and the light source module are supported by the support structure. The plural image regions are arranged between the light source module and the plural lenses. After each of the plural light beams passes through the corresponding image region, the light beam is guided by the grating plate and outputted. Consequently, the image changed with the user's viewpoint and/or the three-dimensional image can be shown on the mouse device. An input device and a computing device with the image displaying device are also provided.

Abstract: An icon display module includes a light blocking structure, a first light-emitting element, a second light-emitting element, a first light-guiding pattern structure and a second light-guiding pattern structure. The light blocking structure includes an accommodation space and a first light-blocking part. The accommodation space is divided into a first region and a second region by the first light-blocking part. When the first light-emitting element emits a first light beam, the first light beam is guided by the first light-guiding pattern structure and the second light-guiding pattern structure and projected on the target. Consequently, a first icon and a second icon are shown on the target. When the second light-emitting element emits a second light beam, the second light beam is guided by the first light-guiding pattern structure and projected to the target. Consequently, the first icon is shown on the target.

Abstract: An image display device a light source, an image display layer and a refractive structure layer. The light source emits a light beam. The image display layer is located over the light source. The image display layer includes plural pattern sections. The refractive structure layer has a reference plane. When the light beam is irradiated on the refractive structure layer and there is a first angle between the light beam and the reference plane, the light beam is guided to a first pattern section, so that a first image is displayed on the image display layer. When the light beam is irradiated on the refractive structure layer and there is a second angle between the light beam and the reference plane, the light beam is guided to a second pattern section, so that a second image is displayed on the image display layer.
