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: 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 light guide module includes a light guide plate, a light-emitting element and a covering layer. The light guide plate includes plural first light-guiding dots and plural second light-guiding dots. The light-emitting element is installed on a lateral edge part of the light guide plate. The covering layer includes a non-shading region, a separation region and a shading region. The plural first light-guiding dots of the light guide plate are aligned with the non-shading region of the covering layer. The plural second light-guiding dots of the light guide plate are aligned with the shading region of the covering layer. The plural second light-guiding dots are covered by the shading region of the covering layer.

Abstract: A housing structure for an electronic device includes a light-transmissible housing body, a first light-shielding layer, a second light-shielding layer, a protective layer and an engraved trench. The first light-shielding layer is formed on a second surface of the light-transmissible housing body. The engraved trench is formed in the second surface of the light-transmissible housing body and not covered by the first light-shielding layer. The second light-shielding layer is formed on a first surface of the light-transmissible housing body. The protective layer is formed over the second light-shielding layer. A pattern corresponding to the engraved trench is visible.
