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.

Abstract: A luminous touch pad includes a covering plate, a circuit board, a light guide structure and a first light-shading adhesive. The covering plate includes a first surface and a second surface. The circuit board is located under the covering plate. The circuit board includes a third surface and a fourth surface. The light guide structure is arranged between the covering plate and the circuit board. The light guide structure includes a lateral surrounding surface. An adhesive receiving space is defined by the lateral surrounding surface, a portion of the second surface and a portion of the third surface collaboratively. The first light-shading adhesive is disposed within the adhesive receiving space and arranged around the light guide structure. The first light-shading adhesive is contacted with the portion of the second surface, the portion of the third surface and the lateral surrounding surface.

Abstract: A semiconductor light emitting unit and a packaging method of the semiconductor light emitting unit are provided. The packaging method includes the following steps. In a step (a), a transparent substrate is provided. In a step (b), a transparent membrane circuit layer is formed on a surface of the transparent substrate. In a step (c), a semiconductor light emitting chip is formed on the transparent membrane circuit layer by a flip-chip mounting process, so that the semiconductor light emitting chip and the transparent membrane circuit layer are electrically connected with each other. In a step (d), an encapsulant is formed over the semiconductor light emitting chip to cover the semiconductor light emitting chip and a portion of the transparent membrane circuit layer. In a step (e), the encapsulant is baked.

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: A touch module includes a light guide plate, a light source module, a conductive circuit and a protective cover. The light source module emits a light beam. The light guide plate includes plural luminous patterns. The conductive circuit is disposed on a top surface of the light guide plate. When a touch action of a finger is detected by the conductive circuit, a touch signal is generated. The protective cover is placed over the light guide plate and the conductive circuit to cover and protect the conductive circuit, and touchable by the finger. When the light beam is projected to the plural luminous patterns, the plural luminous patterns are shown on the protective cover. When the light beam is not generated, the plural luminous patterns are not shown on the protective cover.
