DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Please refer to Figs. 1 to 4 for an electronic device 100 and a dynamic random access memory 1 thereof of a preferred embodiment of the present invention. The dynamic random access memory 1 includes a main body 20, a light-emitting portion 30 and a transmission port 40.
The main body 20 includes a substrate 23 and a first coating layer 21. Specifically, the substrate 23 has a light-transmittable portion 230 and a first face 231, the first coating layer 21 is coated on the first face 231, the first coating layer 21 has an emergent light-transmittable portion 210 corresponding to the light- transmittable portion 230. In this embodiment, the first coating layer 21 at least shields a part of the light-emitting portion 30. Specifically, the first coating layer 21 shields the light-emitting portion 30 thoroughly, the light from the light-emitting portion 30 is guided (refracted or reflected) through the light-transmittable portion 230 and transmitted to the emergent light-transmittable portion 210 so that the light projected is softer. In other embodiments, the light-emitting portion may be not shielded by the first coating layer and be arranged facing the emergent light-transmittable portion; or, the light-emitting portion is partially shielded.
The light-emitting portion 30 is embedded in the substrate 23, and the light from the light-emitting portion 30 can be projected to the light-transmittable portion 230 and projected through the emergent light-transmittable portion 210 to an exterior of the dynamic random access memory 1. It is to be noted that the substrate 23 is a translucent board of a normal printed circuit board. In other embodiments, the light-transmittable portion may be a layer made of a light-transmittable material, and other parts of the substrate may be a layer made of a light-nontransmittable material so that a light-emitting face of the light-emitting portion (which may be partially embedded in the layer made of the light-nontransmittable material) faces the light-transmittable portion directly to emit light; or, the light-transmittable portion is a hollow-out structure, and the light-emitting face of the light-emitting portion is exposed through the hollow-out structure.
The substrate 23 is provided with a memory module 233, the transmission port 40 is disposed on the substrate 23, and the transmission port 40 is electrically connected with the memory module 233. More specifically, the light-emitting portion 30 is also electrically connected with the transmission port 40 (of course, the light-emitting portion may be further electrically connected with other exterior powers such as a mother board). It is understandable that the transmission port 40 can transmit not only electricity but also data.
In this embodiment, the substrate 23 has a second face 232 opposite to the first face 231, the main body 20 includes a second coating layer 22 coated on the second face 232, and the second coating layer 22 at least shields a part of the light-emitting portion 30 (the second coating layer may also not shield the light-emitting portion and allow the light to penetrate directly).
In this embodiment, the first coating layer 21 and the second coating layer 22 are insulting coating layers of a normal circuit board. The emergent light-transmittable portion 210 is a hollow-out structure which is not coated. In other embodiments, the emergent light-transmittable portion may be a layer made of a light-transmittable material. Specifically, the emergent light-transmittable portion 210 is a light-transmittable pattern portion (for example, a trademark) so that the present invention is more appealing when being viewed from outside.
Specifically, the light-emitting portion 30 includes a plurality of light-emitting diodes 31 which are embedded in the substrate 23 along a contour of the emergent light-transmittable portion 210 so that light projected from the emergent light-transmittable portion 210 is brighter and more even.
The electronic device 100 includes the dynamic random access memory 1 mentioned above and further includes a shell portion 50.
The shell portion 50 is covered on two opposite lateral faces of the dynamic random access memory 1. The shell portion 50 further has a second light-transmittable portion 51 corresponding to the emergent light-transmittable portion 210, and the light projected from the emergent light-transmittable portion 210 can be projected through the second light-transmittable portion 51 to an exterior of the electronic device 100. It is understandable that the second light-transmittable portion 51 may be a hollow-out structure or a layer made of a light-transmittable material.
In this embodiment, the shell portion 50 is a heat-dissipating shell portion (the shell portion may made of, for example, a metal) to prevent the dynamic random access memory 1 from overheating.
Given the above, the electronic device and the dynamic random access memory thereof, wherein light is emitted through the light-emitting portion embedded in the substrate and the emergent light-transmittable portion of the coating layer without a light-guiding portion which needs to be further disposed. Therefore, a thickness of the present invention decreases, and a manufacturing cost of the present invention is lower.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
