Description

Technical Field

[0001] The present application belongs to the technical field of displays, and more specifically, to a waterproof display device. Background Art

[0002] LED displays are widely used in outdoor advertising, information release, stage performances and other fields due to their high brightness, high contrast and long life. However, a major challenge facing LED displays in outdoor environments is their insufficient waterproof performance. When encountering rainy and snowy weather, moisture can easily penetrate into the display through the gaps and interfaces, causing problems such as circuit board short circuits and component damage, seriously affecting the normal operation and service life of the display.

[0003] In order to improve the waterproof performance of LED displays, some technical attempts have been made. For example, waterproof materials such as plastic and rubber are used on the display housing to improve the waterproof performance; guide grooves are set inside the display to prevent moisture from being retained inside. However, these technologies still have some problems in practical applications. First, the selection and installation process of waterproof materials have a direct impact on the waterproof effect. If they are not selected properly or not installed properly, the waterproof effect will be poor. Secondly, improper setting of the guide groove will also affect the waterproof effect. In addition, as the use time increases, the performance of the waterproof material may gradually decrease, resulting in a decrease in the waterproof effect. Utility Model Content

[0020] The present application provides a waterproof display device, which includes a waterproof display screen, a box and a water baffle. The waterproof display screen is an imaging component of the waterproof display device, which includes a substrate, a first waterproof structure arranged on the front and side of the substrate, and a second waterproof structure arranged on the back of the substrate. A plurality of lamp beads are welded on the substrate, and the image is presented by controlling the on and off of the lamp beads.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] like Figure 1 and Figure 2 , Figures 6 to 8 As shown, the present application provides a waterproof display device with better waterproof performance, which includes a waterproof display screen 1, a box body 2 and a water retaining plate 3.

[0043] The waterproof display screen 1 is an imaging component of a waterproof display device, which includes a substrate 11, a first waterproof structure provided on the front and side of the substrate 11, and a second waterproof structure provided on the back of the substrate 11. A plurality of lamp beads are welded on the substrate 11, and the image is presented by controlling the on and off of the lamp beads. The first waterproof structure is used to isolate moisture from invading from the front and side of the substrate 11; the second waterproof structure is used to ensure that moisture cannot penetrate from the back of the substrate 11. With the protection of these two waterproof structures, the waterproof display screen 1 itself has a high waterproof performance.

[0044] In addition to being used to carry the waterproof display screen 1, the box 2 is also a carrier of electrical components such as a power supply assembly and a receiving card assembly. In order to ensure the safety of these key electrical components, a power supply waterproof structure 21 is provided on the power supply assembly, and a receiving card waterproof structure 22 is provided on the receiving card assembly. These waterproof structures can prevent moisture from contacting the electrical components, thereby ensuring the stable operation of the waterproof display device.

[0045] Even if the waterproof design is considered separately on the waterproof display screen 1 and the box body 2, external moisture can still invade the interior of the waterproof display device from the gap at the connection between the two. For this reason, a water retaining plate 3 is added between the waterproof display screen 1 and the box body 2 to prevent external moisture from invading the interior of the waterproof display device from the gap at the connection. Specifically, the waterproof display screen 1 is connected to the front side of the water retaining plate 3, and the box body 2 is connected to the rear side of the water retaining plate 3. The water retaining function of the water retaining plate 3 is achieved through the water retaining flange 31. The water retaining flange 31 extends to the box body 2 along the thickness direction of the box body 2. When external moisture falls on the surface of the water retaining flange 31, the moisture will flow to the rear end of the box body 2 along its surface under the guidance of the water retaining flange 31, thereby avoiding the moisture from directly entering the gap between the box body 2 and the water retaining plate 3. Similarly, the water retaining flange 31 can also extend onto the waterproof display screen 1 along the thickness direction of the waterproof display screen 1. When external moisture falls on the surface of the water retaining flange 31, the moisture flows to the front end of the waterproof display screen 1 under the guidance of the water retaining flange 31, and cannot directly flow into the gap between the waterproof display screen 1 and the water retaining plate 3, thereby playing a waterproof role.

[0046] The waterproof display device of the present application has a triple waterproof structure formed by the waterproof display screen 1, the box body 2 and the water retaining plate 3. Whether in daily use or in harsh environmental conditions, the waterproof display device can ensure stable operation.

[0047] like Figure 1 and Figure 3 As shown, in one embodiment of the present application, the water retaining plate 3 includes a first water retaining flange, and the first water retaining flange is arranged at the upper edge of the water retaining plate 3. When the water retaining plate 3 is installed and used, the first water retaining flange can be hung against the upper surface of the box body 2. The first water retaining flange also extends toward the rear end of the box body 2 along the thickness direction of the box body 2, thereby forming a water retaining barrier. When external precipitation falls on the surface of the first water retaining flange, the water will flow toward the rear end of the box body 2 under the guidance of the surface of the first water retaining flange, thereby preventing the water from directly entering the gap between the box body 2 and the water retaining plate 3.

[0048] In one embodiment of the present application, in order to improve the all-round water blocking of the water retaining plate 3, the water retaining plate 3 also includes a second water retaining flange, which extends along the thickness direction of the box body 2 to the side of the box body 2, and the second water retaining flange is used to prevent moisture from penetrating into the interior of the waterproof display device from the side gap of the box body 2. Specifically, there are two second water retaining flanges, one of which is attached to the left side of the box body 2, and the other second water retaining flange is attached to the right side of the box body 2, so as to respectively block the gaps on the left and right sides of the box body 2, thereby preventing the formation of a channel for moisture to penetrate.

[0049] In one embodiment of the present application, the first water retaining flange and the second water retaining flange are foldably connected to the water retaining plate 3, so that the first water retaining flange and the second water retaining flange can adapt to the changes in the upper surface inclination angle and the side inclination angle of different boxes 2. The foldable design of the first water retaining flange allows it to be adjusted according to the inclination angle of the upper surface of the box 2. Regardless of whether the upper surface of the box 2 is a horizontal surface or a surface with a certain inclination angle, the first water retaining flange can be attached to the upper surface of the box 2 to form a water retaining barrier, effectively preventing moisture from penetrating from the upper end gap of the box 2. Similarly, the foldable feature of the second water retaining flange also allows it to be attached to the side of the box 2 to prevent moisture from penetrating into the waterproof display device from the side gap.

[0050] In other embodiments of the present application, the water retaining plate 3 may also be provided with a fourth water retaining flange facing the waterproof display screen 1. The fourth water retaining flange is used to shield the gap above the waterproof display screen 1 to prevent water from penetrating into the waterproof display device from the gap above the waterproof display screen 1.

[0051] like Figure 3 As shown, in one embodiment of the present application, the water baffle 3 includes a plurality of magnetic parts 32 respectively arranged on the front side and the rear side. The main function of the magnetic part 32 located on the front side of the water baffle 3 is to achieve magnetic adsorption with the waterproof display screen 1. The magnetic part 32 located on the rear side of the water baffle 3 is responsible for magnetic adsorption with the box body 2, so as to achieve magnetic adsorption of the waterproof display screen 1 to the water baffle 3, and then magnetically connect the water baffle 3 to the box body 2 to complete the assembly of the waterproof display device. Through magnetic adsorption, the connection between the water baffle 3 and the waterproof display screen 1 and the box body 2 is not only stable and reliable, but also easy to disassemble and install.

[0052] like Figure 3 As shown, in one embodiment of the present application, in consideration of the need for wiring of the internal wires of the waterproof display device, the water retaining plate 3 further includes a threading hole 33, and the threading hole 33 is arranged facing the waterproof display screen 1 or the box body 2, so that the wires of the waterproof display screen 1 or the box body 2 pass through the water retaining plate 3. It should be noted that the threading hole 33 cannot be arranged on the first water retaining flange and the second water retaining flange, so as not to affect the water retaining performance of the first water retaining flange and the second water retaining flange.

[0053] like Figures 6 to 8 As shown, in one embodiment of the present application, the first waterproof structure is a glue-filled waterproof layer 12, and the glue-filled waterproof layer 12 covers the front and side surfaces of the substrate 11. The glue-filled waterproof layer 12 is specifically transparent and colorless, and does not affect the brightness of the lamp beads on the substrate 11. The glue-filled waterproof layer 12 can effectively prevent moisture from penetrating into the display screen from the front and side surfaces of the substrate 11, thereby protecting the lamp beads, solder joints, etc. on the waterproof display screen 1.

[0054] Specifically, the glue-filled waterproof layer 12 is made on the substrate 11 by the GOB process. Taking the waterproof display screen 1 with a plane size of 249.95*249.95 as an example, the GOB process is performed on the front and side of the blank (with a size of 249.2*249.2), and the size after the GOB process is controlled to 250.5*250.5, and then the display screen after the GOB process is processed to 249.95*249.95 by machining, so as to obtain the glue-filled waterproof layer 12 that meets the requirements.

[0055] like Figures 6 to 8 As shown, in one embodiment of the present application, the second waterproof structure includes a coated waterproof layer 13 and a waterproof signal seat 14. The coated waterproof layer 13 covers the back of the substrate 11 to isolate moisture from penetrating into components such as capacitors and resistors on the back of the substrate 11, thereby protecting the waterproof display screen 1. The waterproof signal seat 14 is electrically connected to the lamp beads on the substrate 11.

[0056] like Figure 4 and Figure 5 As shown, in one embodiment of the present application, the power supply waterproof structure 21 and the receiving card waterproof structure 22 are both waterproofed by a waterproof cover. The waterproof cover isolates the power supply component and the receiving card component in the box 2, and the edge of the waterproof cover is also filled with waterproof glue to further improve the waterproof ability of the waterproof cover.

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
