Description

Technical Field

[0001] The utility model relates to an external electronic device, in particular to an external electronic display device for providing information display. Background Art

[0002] Upon investigation, the internal space of existing electronic display devices can provide object displayers, as disclosed in TW I815580 in Taiwan, China, TW I778508 in Taiwan, China, and US2013107160. However, the display modules on the electronic display devices proposed in the aforementioned patents all come with backlight components. As a result, the aforementioned electronic display devices are limited by the thickness of the backlight components and cannot effectively reduce the overall thickness of the electronic devices. On the other hand, the visual experience provided by current electronic display devices is still mainly based on a simple liquid crystal screen or a simple space display, and it is impossible to generate different visual effects by combining the two.

[0003] In addition to the above, existing computer peripheral devices generally display their own working status during operation. Taking a computer host as an example, a display screen is arranged on the surface of its host case, and the display screen displays the working status of the computer host when the computer host is working, such as the temperature of the arithmetic processor, the temperature of the graphics card, etc. For details, reference can be made to CN216352112U, CN220829697U, CN220691348U, etc. However, the conventional display screen is limited by the placement position of the computer host. In practice, the computer host is generally set under the computer desk or behind the computer screen, that is, the computer host is not placed in a position where the user can clearly observe it by raising their eyes. As a result, if the user wants to know the current working status of the computer host, they have to get up or lower their heads specifically to observe the display screen arranged on the computer host, which is not convenient for the user. Moreover, the display screen disclosed in the aforementioned patents is assembled on the computer host, which requires improving the computer host case, increasing the process, and raising the manufacturing cost. In addition, the conventional method will limit the display screen to be assembled only on a specific computer host, which is not conducive to implementation. Summary of the Utility Model

[0004] The main purpose of the utility model is to solve the problem of the monotonous visual experience provided by conventional electronic display devices.

[0005] Another purpose of the utility model is to solve the problem that the display screen arranged on the conventional computer peripheral device is not convenient for the user to operate and is not conducive to manufacturing.

[0006] To achieve the above object, the present utility model provides an external electronic display device, which includes a housing, a light-emitting component, a circuit board, and a liquid crystal panel. The housing forms an inner housing space. The light-emitting component is disposed in the inner housing space. The circuit board is located in the inner housing space and is provided with a connection port exposed on the surface of the housing. The circuit board drives the light-emitting component to generate light in the inner housing space. The liquid crystal panel is disposed on the housing and exposed on the surface of the housing. When the inner housing space is bright, the information displayed by the liquid crystal panel can be observed. The liquid crystal panel does not limit the observation of the inner housing space through the outside of the housing.

[0007] In one embodiment, at least one side of the circuit board facing the light-emitting component is a color with a high reflectivity.

[0008] In one embodiment, a first reflective layer is provided on at least one side of the circuit board facing the light-emitting component.

[0062] The detailed description and technical content of the present utility model will be described below in conjunction with the accompanying drawings:

[0063] Please refer to Figure 1 , the present utility model provides an external electronic display device 20, which can be used as a computer peripheral device. The external electronic display device 20 is placed on a computer desk 90 to display a dynamic picture or assist in displaying the working state of another computer peripheral device (such as a computer main unit 91, a heat dissipation device).

[0064] Please refer to again Figures 2 to 4 , the external electronic display device 20 includes a housing 21, a light-emitting component 23, a circuit board 24, and a liquid crystal panel 25. The housing 21 forms an inner housing space 211. The light-emitting component 23 is disposed in the inner housing space 211 and generates light (such as 231 in Figure 4 ) when activated. The circuit board 24 is disposed in the inner housing space 211 and is provided with a connection port 241 exposed on the surface of the housing 21. The connection port 241 provides the external connection function of the external electronic display device 20. More specifically, the housing 21 is provided with an installation opening 212, and the connection port 241 is disposed in the installation opening 212 to connect to an external electronic device and receive the display signal and the power required for operation transmitted by the external device. The circuit board 24 is electrically connected to the light-emitting component 23 and drives the light-emitting component 23 based on a pre-written program or a signal received by the connection port 241, so that the inner housing space 211 generates light.

[0065] The liquid crystal panel 25 is disposed on the housing 21 and is exposed on the surface of the housing 21 for the outside to directly observe the liquid crystal panel 25 from the outside of the housing 21. In one embodiment, the housing 21 is provided with an opening 213 for exposing the liquid crystal panel 25. The liquid crystal panel 25 of the present utility model only includes components for display and does not include parts that can emit light or conduct light (such as a backlight panel). Therefore, the light required for the liquid crystal panel 25 of the present utility model to display information is obtained from parts other than the liquid crystal panel 25. Furthermore, since the liquid crystal panel 25 of the present utility model only includes components for display, there is no restriction that the outside can see through the liquid crystal panel 25 and directly observe the inner housing space 211.

[0066] When the external electronic display device 20 of the present utility model is implemented, it is connected to the external electronic device to obtain the power or display signal required during operation. The aforementioned display signal can be the current operating temperature, brand logo, or animation of the external electronic device, etc. The liquid crystal panel 25 is not limited to normal display. When the liquid crystal panel 25 is displaying information and the interior space 211 of the housing is bright, the brightness of the interior space 211 can be directly observed through the liquid crystal panel 25. At the same time, at least one electronic component 240 on the circuit board 24 can also be observed, and the visual experience is like Figure 5 . When the liquid crystal panel 25 receives the display signal and the light-emitting component 23 is activated, the liquid crystal panel 25 can, based on the brightness of the interior space 211, make the displayed information observable. At this time, the interior space 211 allows for direct perspective observation, and the liquid crystal panel 25 can cooperate with the interior space 211 to produce different visual effects, just like Figure 6 shown. The liquid crystal panel 25 can, according to the plan, make the picture cooperate with the at least one electronic component 240 on the circuit board 24 to produce overlapping, shielding (as Figure 7 shown) or interleaved visual aesthetics. Furthermore, when the present utility model is implemented, the interior space 211 of the housing is not limited to normal light emission. When the light-emitting component 23 does not generate light, the display of the liquid crystal panel 25 cannot be observed, but the interior space 211 still allows for perspective observation. That is to say, the outside world can still try to observe the at least one electronic component 240 on the circuit board 24 by approaching the housing 21.

[0067] In summary, it can be seen that in the present utility model, by not having a backlight panel on the liquid crystal panel 25, the external electronic display device 20 can not only display information but also display the interior space 211 and present diverse visual experiences. At the same time, through the design of not having a backlight panel on the liquid crystal panel 25, the overall height of the external electronic display device 20 of the present utility model can be reduced. On the other hand, the external electronic display device 20 of the present utility model does not limit the computer peripheral devices with which it is implemented, and there is no need to modify the structure of the computer peripheral devices with which it is implemented, which is conducive to implementation. At the same time, the external electronic device 20 of the present utility model can be directly observed by the user by looking up, without having to get up or bend down specifically to observe.

[0068] Please refer back to Figure 8, in this utility model, the circuit board 24 and the liquid crystal panel 25 are arranged in parallel and at intervals. The light-emitting component 23 is disposed between the circuit board 24 and the liquid crystal panel 25. The light generated by the light-emitting component 23 is reflected by the circuit board 24 and enters between the liquid crystal panels 25 to improve the display of the liquid crystal panel 25. In order to make the display of the liquid crystal panel 25 clearer, in one embodiment, at least one side of the circuit board 24 facing the light-emitting component 23 is a color with a high reflectivity. The high-reflectivity color can be white or silver. Through the high-reflectivity color, the light generated by the light-emitting component 23 can be reflected into the liquid crystal panel 25, thereby effectively improving the light utilization rate of the light-emitting component 23 and further improving the display of the liquid crystal panel 25. In this embodiment, the preparation method of the circuit board 24 with a high reflectivity color can be formed by coating. That is to say, a coating is provided on at least one side of the circuit board 24 facing the light-emitting component 23 to form a first reflective layer 242.

[0069] Further, in this utility model, the light-emitting component 23 includes a plurality of light sources 232 and at least one carrier board 233 for providing the plurality of light sources 232. The at least one carrier board 233 can be a flexible circuit board. When the plurality of light sources 232 are activated, they generate light. The plurality of light sources 232 are arranged around the inner space 211 of the housing to make the display of the liquid crystal panel 25 uniform. There are two light projection directions of the plurality of light sources 232. One is facing the circuit board 24 and directly projecting light onto the circuit board 24, as shown in Figures 2 to 9 drawn, and the other is parallel to the surface of the circuit board 24. Although the plurality of light sources 232 do not directly project light onto the circuit board 24, the light generated by the plurality of light sources 232 is indirectly affected by the circuit board 24 and can still be reflected to the liquid crystal panel 25, as shown in Figures 10 to 13 . It should be understood that the aforementioned light projection directions do not limit the light generated by the plurality of light sources 232 to be directional, but can be defined by the central axis of the light generated by each of the plurality of light sources 232.

[0070] Continuing, please refer to Figure 9 again. In one embodiment, the housing 21 is provided with a support 214 located in the inner space 211 of the housing, and the support 214 provides a setting for the carrier board 233. In this utility model, in order to more effectively improve the use of the light of the light-emitting component 23 for the display of the liquid crystal panel 25, in one embodiment, the surface of the support 214 can also be a color with a high reflectivity. The surface of the support 214 faces the inner space 211 of the housing. Implementing the surface of the support 214 with a high reflectivity color can reflect the light projected by the light-emitting component 23 into the inner space 211 of the housing and assist in the display of the liquid crystal panel 25. There are two methods for the surface of the support 214 to have a high reflectivity. One is to select a material with a high reflectivity color when manufacturing the support 214, and the other is to provide a coating on the surface of the support 214 to form a second reflective layer 215.

[0071] Also, please refer to Figures 2 to 9 , in the present utility model, the carrier 214 is provided for positioning the light-emitting component 23. When the plurality of light sources 232 are arranged with their own light projection directions facing the circuit board 24, the carrier 214 is formed with a plurality of positioning ports 216, and the plurality of positioning ports 216 face the circuit board 24 to provide a setting position for the plurality of light sources 232. Please refer to again Figures 10 to 13 , when the plurality of light sources 232 are arranged with their own light projection directions parallel to the surface of the circuit board 24, the carrier 214 is provided with at least one mounting rib 217, and the at least one mounting rib 217 provides a setting position for the plurality of light sources 232 and provides a stopping function. In addition, the carrier 214 of the present utility model may also be provided with at least one support column 218 for assembling the circuit board 24, and the at least one support column 218 abuts against one side of the circuit board 24 and limits the assembling position of the circuit board 24.

[0072] Please refer to again Figure 9 , in order to improve the display of the liquid crystal panel 25, in one embodiment, the housing 21 has an inner wall surface 219, the inner wall surface 219 faces the inner space 211 of the housing, and the inner wall surface 219 may also be a color with a high reflectivity. Implementing the inner wall surface 219 with a color of high reflectivity can reflect the light projected by the light-emitting component 23 into the inner space 211 of the housing to assist the display of the liquid crystal panel 25. There are three methods for the inner wall surface 219 to have a high reflectivity color. One is that when the housing 21 is composed of at least two housing parts 220, one of the at least two housing parts 220 that define the inner space 211 is made of a material with a high reflectivity color during production. The second is that when the housing 21 is implemented with a single part, the housing 21 is made of a material with a high reflectivity color during production. The third is that a coating is provided on the inner wall surface 219 of the housing 21 to form a third reflective layer 221.

[0073] On the other hand, Figures 2 to 4 , in one embodiment, at least one connection port 243 is provided on the circuit board 24, and the at least one connection port 243 is electrically connected to the liquid crystal panel 25 and the light-emitting component 23. The at least one connection port 243 connects the liquid crystal panel 25 and the light-emitting component 23 with at least one of the following or a combination thereof: at least one electrical wire and a flexible cable (such as reference numeral 254), and the at least one connection port 241 transmits the required power and display information for work through at least one of the above-mentioned components.
