Description

Technical Field

[0001] The utility model relates to the technical field of screen production, in particular to an ELED display structure and a display. Background Art

[0002] See also Figure 1 Currently, the structure of an ELED display primarily consists of a front frame, a rear cover, an LED light bar, a sheet, a light guide plate, a reflector, a heat sink, a back plate, and a middle frame. The front frame and rear cover can be assembled to form a mounting cavity, within which the LED light bar, sheet, light guide plate, reflector, heat sink, back plate, and middle frame are all placed. The heat sink dissipates heat from the LED light bar. If a heat sink is not present, heat can also be dissipated through the back plate. Therefore, to ensure the heat dissipation performance of the LED light bar, existing ELED display structures inevitably require the installation of a heat sink or back plate during production.

[0003] As the application fields of ELED display structures increase, the models of ELED display structures also increase accordingly. Therefore, in the production process of different models of ELED display structures, it is necessary to develop corresponding models of molds according to the models of ELED display structures to produce different models of front frames, rear covers, LED light strips, sheets, light guide plates, reflective plates, heat dissipation plates, back plates and middle frames, etc. However, due to the long mold development cycle and high development costs of heat dissipation plates and back plates, the production cycle of the entire ELED display structure is increased, and the production cost is increased.

[0004] Therefore, the above problems need to be solved urgently. Utility Model Content

[0039] In order to shorten the production cycle of the ELED display structure and reduce the production cost of the ELED display structure, an ELED display structure is proposed in this embodiment, which omits the installation of the middle frame, heat dissipation plate and back plate in the structure, thereby avoiding the development of manufacturing molds for the middle frame, heat dissipation plate and back plate during the production process of the ELED display structure.

[0040] Specifically, see Figure 2 and Figure 3 The ELED display structure includes a front frame 1, a rear cover 2, an LED light bar 3, a sheet 4, a light guide plate 5 and a reflective plate 6. The front frame 1 can be assembled with the rear cover 2 to form an installation cavity with an opening, and the rear cover 2 is arranged opposite to the opening; along the direction from the opening to the rear cover 2, the sheet 4, the light guide plate 5 and the reflective plate 6 are stacked in sequence in the installation cavity; the LED light bar 3 is arranged on the inner wall of the front frame 1, and the light-emitting unit 32 of the LED light bar 3 is opposite to the side wall of the light guide plate 5; the front frame 1 is made of heat-conductive material.

[0041] It can be understood that the LED light strip 3 is directly set on the inner wall of the front frame 1, and the LED light strip 3 can be cooled under the action of the front frame 1. Compared with the traditional ELED display structure, the ELED display structure omits the installation of the middle frame 9, the heat dissipation plate 7 and the back plate 8. Therefore, during the production process, there is no need to consider the development of the mold for the middle frame 9, the heat dissipation plate 7 and the back plate 8, thereby improving the production cycle of the ELED display structure and reducing the production cost.

[0042] Exemplarily, the front frame 1 is a four-sided frame structure, and the back cover 2 is sealed on one side of the front frame 1 to form an installation cavity with an opening. Along the direction from the opening to the back cover 2, the sheet 4, the light guide plate 5 and the reflective plate 6 are stacked in sequence in the installation cavity.

[0043] To ensure the stability of the backlight emitted by the LED light strip 3 during transmission to the light guide plate 5, it is necessary to ensure that the backlight can be vertically incident on the side wall of the light guide plate 5. The sheet 4, the light guide plate 5, and the reflective plate 6 constitute a light transmission component. The ELED display structure further includes a support portion 10, which is disposed in the mounting cavity and is used to support and fix the light transmission component so that the side wall of the light guide plate 5 is arranged parallel to the light-emitting unit 32. It is understood that the support portion 10 can support the light transmission component to ensure that the side wall of the light guide plate 5 is arranged parallel to the light-emitting unit 32. In addition, the support portion 10 can fix the light transmission component to prevent movement of the light transmission component, thereby further ensuring the stability of the backlight during transmission.

[0044] Specifically, the ELED display structure further includes an extension portion 11, which is disposed on the side of the front frame 1 adjacent to the opening and capable of extending toward the interior of the mounting cavity. The support portion 10 includes a first support assembly 1001 and a second support assembly 1002. The first support assembly 1001 is disposed on the extension portion 11, and the second support assembly 1002 is disposed on the rear cover 2. The light transmission assembly is clamped between the first support assembly 1001 and the second support assembly 1002. It is understood that the first support assembly 1001 is disposed between the extension portion 11 and the light transmission assembly, and the second support assembly 1002 is disposed between the rear cover 2 and the light transmission assembly. The first support assembly 1001 and the second support assembly 1002 can limit the two sides of the light transmission assembly to form a fixed position, thereby preventing the light transmission assembly from shifting.

[0045] Exemplarily, the extension portion 11 includes a plurality of extension plates, which can be arranged around the opening to ensure the supporting performance of the first support assembly 1001 .

[0046] In addition, the structure of the first support component 1001 is consistent with that of the second support component 1002. The specific structure of the first support component 1001 is explained here. The first support component 1001 includes foam, which is arranged between the extension part 11 and the light transmission component. It can not only support the light transmission component, but also increase the sealing performance between the light transmission components.

[0047] Furthermore, the first support assembly 1001 further includes a support member, which is disposed between the foam and the light transmission assembly. The support member can compensate for the compression of the foam during the support process, thereby further ensuring the stability of the backlight during the transmission process. The support member is preferably a sheet structure made of EVA or PE material.

[0048] In this embodiment, the LED light strip further includes a base 31 for securing the light-emitting unit 32. The base 31 is disposed on the inner sidewall of the front frame 1. The ELED display structure further includes a protrusion 12 disposed on the extension 11. The protrusion 12 is located below the light-emitting unit 32 and is capable of affixing to the sidewall of the base 31 facing away from the front frame 1. It is understood that the protrusion 12, the extension 11, and the front frame 1 can be assembled to form a recess for accommodating a substrate. When the substrate is disposed in the recess, it can maintain affixment with the protrusion 12 and the front frame 1, respectively, thereby increasing the heat dissipation area of the heat-dissipating LED light strip and thereby extending the service life of the LED light strip.

[0049] In addition, the protrusion 12 , the extension portion 11 and the front frame 1 are preferably formed in one piece, and such a configuration can further ensure the heat dissipation performance of the LED light strip 3 .

[0050] Furthermore, the end of the reflector 6 can abut against the base 31, and the reflector 6 is located above the light-emitting unit 32. It is understood that the abutment between the reflector 6 and the base 31 can seal the light-emitting unit 32, thereby preventing dust and other debris from entering the electronic components of the light-emitting unit 32, thereby further improving the service life of the LED light strip.

[0051] In this embodiment, the front frame 1 is composed of a plurality of profiles, so that the model of the front frame 1 can be adjusted according to different needs, thereby further shortening the production cycle of the ELED display structure.

[0052] Furthermore, the profile is hollow, which can reduce the weight of the front frame 1 and thus reduce the overall weight of the display to meet the lightweight characteristics of the display.

[0053] Furthermore, the front frame 1 is made of metal. Since metal has good thermal conductivity, it can dissipate heat from the LED light bar 3. In addition, the metal material is preferably a lightweight metal such as aluminum, which can further meet the lightweight characteristics of the display.

[0054] In addition, a step surface 101 is provided on the side of the front frame 1 away from the opening, and the rear cover 2 overlaps the step surface 101. This arrangement can reduce the overall thickness of the ELED display structure, thereby meeting the characteristics of the display being thin and light.

[0055] This embodiment also provides a display comprising the aforementioned ELED display structure. It is understood that a display employing the aforementioned ELED display structure can avoid the development of molds for the middle frame 9, heat sink 7, and back panel 8 during production, thereby shortening the entire display production cycle and reducing production costs.

[0056] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
