The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIG. 1 to FIG. 4, an electronic device 100 and a dynamic random access memory 1 thereof are shown in a preferred embodiment of the present invention. The dynamic random access memory 1 includes a body 10 and a transport port 40.

The body 10 has a substrate portion 20 and a light emitting portion 30. The substrate portion 20 is provided with a memory module 233. The transmission port 40 is disposed on the substrate portion 20, and the transmission port 40 is electrically connected to the memory module 233. In more detail, the light-emitting portion 30 is also electrically The transmission port 40 is connected (of course, the light-emitting portion can be additionally electrically connected to other external power sources such as a motherboard). It can be understood that the transmission port 40 can not only transmit power but also transmit data.

The substrate portion 20 includes a substrate 23 and a first lacquer layer 21. Further, the substrate 23 has a transparent portion 230 and a first surface 231. The first lacquer layer 21 is disposed on the first surface 231. The substrate 23 is integrally formed with the transparent portion 230. The lacquer layer 21 is provided with an outgoing light transmitting portion 210 corresponding to the light transmitting portion 230. The light source of the light emitting portion 30 can pass through the light transmitting portion 230 and be emitted from the outgoing light transmitting portion 210 to the dynamic random access memory. 1 outside. In the embodiment, the substrate 23 further has a second surface 232 different from the first surface 231. More specifically, the first surface 231 is opposite to the second surface 232. The substrate portion 20 includes a cover. The second lacquer layer 22 is disposed on the second lacquer layer 22, and the second lacquer layer 22 is provided with an incident light transmitting portion 220 corresponding to the transparent portion 230. The light source of the illuminating portion 30 can pass through the incident light transmitting portion 220. The light is transmitted to the light transmitting portion 230. In other embodiments, the second lacquer layer and the incident light transmitting portion may not be disposed, and the light source of the illuminating portion may be passed through; or the light source of the illuminating portion may pass through other regions of the substrate without being incident through the second surface (for example, phase Irrespective of the other side of the second side) incident.

In this embodiment, the first lacquer layer 21 and the second lacquer layer 22 are insulating varnish layers on a general circuit board, and the incident light transmitting portion 220 and the outgoing light transmitting portion 210 are unpainted hollows. In other embodiments, the incident and outgoing light transmitting portions may also be light transmissive material layers, which may also transmit light. Further, the outgoing light transmitting portion 210 is a light-transmissive image portion (for example, a logo or the like), and can be more conspicuous and beautiful when viewed from the outside (of course, the incident light transmitting portion may also correspond to the outgoing light transmitting portion. Ministry of Graphic and Art).

Further, the light-emitting portion 30 is disposed on the substrate portion 20, and the light-emitting portion 30 is disposed adjacent to the incident light-transmitting portion 220. The light-emitting portion 30 includes a plurality of outlines along the incident light-transmitting portion 220. The light-emitting diode 31 of the substrate portion 20 can make the light transmitted from the light-emitting and transmitting portion 210 brighter and more uniform. In other embodiments, the light emitting portion may not be disposed on the substrate portion, and the light source of the light emitting portion may be directly or indirectly incident on the light transmitting portion.

The electronic device 100 further includes a case portion 50 in addition to the dynamic random access memory 1 as described above.

The shell portion 50 is disposed on opposite sides of the DRAM 1 and at least shields the illuminating portion 30, thereby preventing the light of the illuminating portion 30 from being excessively strong and injuring the human eye. The housing portion 50 is further provided with a housing transparent portion 51 corresponding to the outgoing light transmitting portion 210. The light source emitted from the outgoing light transmitting portion 210 can be incident on the electronic device 100 via the housing transparent portion 51. Externally, it can be understood that the housing light transmitting portion 51 can be a hollow structure or a light transmissive material layer, so that the light source can be smoothly penetrated.

Preferably, the housing portion 50 is provided with a reflective structure 52 corresponding to the light-emitting portion 30. The reflective structure 52 reflects a portion of the light source of the light-emitting portion 30 to the light-transmitting portion 230. More specifically, the reflective structure 52. It is a concave-convex structure (which may of course be a flat reflective surface), and the light source may be irregularly reflected and uniformly incident on the light transmitting portion 230. In the embodiment, the shell portion 50 is a heat dissipation shell portion (for example, a metal material), and the dynamic random access memory 1 can be prevented from being overheated.

In summary, the electronic device of the present invention and its dynamic random access memory can be used without another The light guiding portion is provided separately, and the same brightening effect can be achieved by using only the structure of the substrate itself and the outgoing light transmitting portion in the lacquer layer, thereby reducing the overall thickness and saving the manufacturing cost.
