Description

Technical Field

[0001] The utility model belongs to the field of display technology, and specifically relates to a display module and a display device. Background Art

[0002] For example, the display device of the LED display screen is an important human-computer interaction medium. From smart watches / bracelets to mobile phones, computers and dedicated service terminals, to display screens for demonstrations, conference screens, advertising screens and other smart devices, all need to use display devices as human-computer interaction media.

[0003] LED display screens are composed of LED dot matrix and panel, which display text, pictures, animation, video and other contents by turning on and off red, blue, white, green and other LED lights. Due to the advantages of high brightness, low operating voltage, low power consumption, large size, long life, impact resistance and stable performance, LED display screens are widely used for outdoor (such as rooftops of buildings and in front of doors and roadsides of commercial areas) advertising, as well as information release in shopping malls, stations, squares, airports, etc.

[0004] As a type of LED display screen, a spliced ​​LED display screen generally includes a shell and multiple LED display modules fixed on the shell. The multiple LED display modules are spliced ​​into a complete display surface. However, the shell of the spliced ​​LED display screen is generally made of cast aluminum or ordinary PC plastic. Cast aluminum requires CNC precision processing, which results in high costs, and ordinary PC plastic has the defects of poor rigidity, low flatness, and large dimensional accuracy tolerance.

[0005] In addition, there are two types of spliced ​​LED display screens: front maintenance and rear maintenance. Generally speaking, in some special installation occasions, for example, when the spliced ​​display screen is installed on the ceiling and the display surface is facing downward, usually only front maintenance can be performed. During front maintenance, the display module needs to be disassembled. However, the existing display module and the shell are directly connected by screws. On the one hand, the display module cannot be maintained from the front. On the other hand, there will be a momentary large suction force when the display module is assembled into the shell, and the display module and the shell are prone to direct collision, causing damage to the display module.

[0006] Therefore, there is an urgent need to provide a display module and a display device that are convenient for front maintenance and prevent the display module from being damaged. Utility Model Content

If there is no conflict, the embodiments of the utility model and the various features in the embodiments can be combined with each other, all within the scope of protection of the utility model.

[0031] refer to Figures 1 to 6As an object of the present invention, a display module is provided, which can be specifically an LED display module. Accordingly, the display device can be specifically an LED display screen, which includes a bottom shell 1 and a plurality of unit boards 2. The bottom shell 1 has a first side portion 11 and a second side portion 12 opposite to each other. It can be known that the first side portion 11 and the second side portion 12 can also be understood as an inner bottom shell facing each unit board 2 and an outer bottom shell opposite to each unit board 2, respectively. A plurality of unit boards 2 are spliced ​​and fixed on the first side portion 11. The first side portion 11 is divided into the same number of fixing portions 111 according to the number of unit boards 2. In this embodiment, the number of unit boards 2 is specifically set to 6. A plurality of support platforms 3, for example, cylindrical, are provided on each fixing portion 111, and a plurality of magnetic suction members 4 for being magnetically attracted to fix the bottom shell 1 are provided on the second side portion 12. Therefore, by arranging multiple support platforms 3 on the first side portion 11 of the bottom shell 1 facing each unit board 2 and corresponding to the multiple fixing portions 111 for fixing the multiple unit boards 2, each unit board 2, especially the unit board 2 using a glass substrate and circuits and light-emitting chips arranged on the glass substrate, can disperse the pressure through multiple small surface supports, especially the circular surface support of the cylindrical support platform 3, rather than being supported by the entire surface and receiving concentrated pressure, so that it is not easy to be crushed. It should be pointed out that in the present utility model, in the absence of conflict, the unit boards 2 all have the above-mentioned glass substrate. In addition, by arranging multiple magnetic suction parts 4 on the second side portion 12 of the bottom shell 1 facing away from each unit board 2, the bottom shell 1 fixed with each unit board 2 can be magnetically assembled with the display module used to accommodate the bottom shell 1 and the unit board 2 to form a whole, so that the screen assembly is fast, and the display module can meet the requirements of being taken out from the front of the screen body of the display device during front maintenance.

[0032] Please refer to the following for further reference Figures 3 to 5 As an additional improvement, an easy-to-pull adhesive 5 is pasted on the back side of each unit board 2 facing the first side portion 11. The easy-to-pull adhesive 5 can meet the high and low temperature hot and cold shock test of about -20 to 60 degrees without debonding or overflowing and has shrinkage elasticity. Specifically, in this embodiment, the easy-to-pull adhesive 5 adopts high-elasticity 3M easy-to-pull adhesive, and a notch 112 is provided at at least one corner of each fixing portion 111. Each notch 112 correspondingly exposes the end edges of four easy-to-pull adhesives 5, so that the exposed end edges can be easily pulled by fingers to separate the easy-to-pull adhesive 5 from the fixing portion 111. Therefore, when the display panel needs to be maintained, it is only necessary to pull out the easy-to-pull adhesives 5 on the back side of one of the unit boards 2 through the reserved notch 112 designed in the bottom shell 1, and then remove the unit board 2 for maintenance.

[0033] Preferably, the fixing portion 111 and the unit board 2 are configured to be compatible with each other, for example, a rectangular or square shape. In this embodiment, the square shape is a rectangular shape. Four easy-to-pull adhesives 5 are attached to the back of each unit board 2. A notch 112 is provided at each of the four corners of the fixing portion 111. The pulling ends of the four easy-to-pull adhesives 5 are exposed from the corresponding notches 112. In this way, not only can each unit board 2 be evenly and firmly attached to the bottom shell 1, but also when the unit board 2 needs to be repaired, each easy-to-pull adhesive 5 can be easily torn out to separate the unit board 2 from the bottom shell 1 for further repair.

[0034] Please refer to the following for further reference Figure 2 and Figure 6 , additionally improved, a plurality of accommodating grooves 121, for example, in the shape of strips, are provided on the edge of the second side portion 12, and a corresponding shock-absorbing pad 6, for example, in the shape of strips, is arranged in each accommodating groove 121, and the shock-absorbing pad 6 can be made of sponge, rubber, etc. In this way, when the display module is assembled with the above-mentioned box body, the contact surface of the box body and the shock-absorbing pads installed on the edge of the second side portion 12 of the bottom shell 1 abut against each other, thereby effectively preventing the instantaneous suction force from being too large during assembly and damaging the glass substrate of the unit board 2;

[0035] Please refer to the following for further reference Figure 2 and Figure 6 In an additional improvement, a plurality of positioning posts 7 for positioning and installing the bottom shell 1 are arranged on the second side portion 12, and each positioning post 7 can be fixedly arranged by welding or by threading a threaded hole opened on the bottom shell and a threaded groove arranged on the outer peripheral surface of one end of the positioning post. In this way, under the guiding effect of each positioning post 7, the display module can be quickly assembled with the box body.

[0036] Please refer to the following for further reference Figure 2 and Figure 6 , additionally improved, a hook 8 for buckling with a safety rope is fixedly installed on the second side portion 12. In this case, by fixing the two ends of the safety rope to the hook 8 and the box, the display module can be prevented from accidentally falling.

[0037] Please refer to the following for further reference Figure 2 and Figure 6 Specifically, the hook 8 is an L-shaped piece, and the long side and short side of the L-shaped piece are respectively provided with a mounting hole and a hanging hole, and the second side portion 12 is provided with a fixing hole, and the L-shaped piece is fixed to the bottom shell 1 by a round head combination screw 9 through the mounting hole and the fixing hole, and a screw hole is provided on the second side portion 12, and a countersunk hole is provided on the magnetic attraction member 4, and the magnetic attraction member 4 is fixed by a countersunk screw 10 through the countersunk hole and the screw hole. Therefore, each L-shaped hook 8 has sufficient rigidity to accept the suspension force, and each hook 8 and each magnetic attraction member 4 can be reliably and conveniently fixed.

[0038] Please refer to the following for further reference Figure 2 and Figure 6 Preferably, the bottom shell 1 is set as a rectangular body as a whole, and the magnetic suction member 4 and the positioning column 7 are both set as multiple and are symmetrically arranged relative to the horizontal center line and the vertical center line of the second side portion 12 of the rectangle. Specifically, in this embodiment, the magnetic suction member 4 and the positioning column 7 are both set as 4, and each positioning column 7 is closer to the horizontal center line and farther away from the vertical center line than each magnetic suction member 4, and the horizontal center line passes through the long side surface of the L-shaped piece. By arranging the magnetic suction member 4, the positioning column 7 and the hook 8 in this way, a relatively better assembly efficiency and positioning effect of the bottom shell 1 can be obtained.

[0039] As an additional improvement, the bottom shell 1 is made of high-strength plastic steel material, namely PPS, which is integrally injection molded. Since high-strength plastic steel can be integrally injection molded, higher rigidity, higher flatness and smaller dimensional accuracy tolerance are obtained while reducing costs.

[0040] Specifically, the unit board 2 includes a glass substrate and circuits and light-emitting chips disposed on the glass substrate. Since the unit board 2 using a glass substrate is relatively more susceptible to vibration, pressure, etc., it is relatively easier to be damaged, crushed, etc., so any of the above-mentioned display modules can be particularly suitable for the unit board 2 with a glass substrate having circuits and light-emitting chips, ensuring the reliable assembly and normal operation of the unit board 2.

[0041] As another object of the present invention, a display device is provided, which includes a plurality of spliced ​​display modules of any of the above types. The display device can especially be an LED display screen. The display device can obtain the beneficial effects brought by any display module, which will not be described in detail here. Therefore, the display device has the advantages of being easy to maintain in the front and preventing the display module from being damaged.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
