DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0026] Reference Figures 1 to 4 , an example of the present invention provides a Mini LED display module with a hole structure, including a back plate 100, a light board 110, a diffuser plate 120 and a DBEF sheet 130 arranged in sequence, a circular tube 140 is provided on the back plate 100, the inner hole of the circular tube 140 is used to install a camera, the light board 110 is fixed to the top of the back plate 100, and a support member 150 is provided on the side of the back plate 100, the support member 150 is used to support the diffuser plate 120 and the DBEF sheet 130, the circular tube 140 passes through the back plate 100, the light board 110, the diffuser plate 120 and the DBEF sheet 130, and a light-shielding foam 160 is provided between the DBEF sheet 130 and the circular tube 140. The light-shielding foam 160 is a circular ring structure and is used to seal the gap between the DBEF sheet 130 and the circular tube 140, thereby preventing light from leaking from the gap between the DBEF sheet 130 and the circular tube 140, thereby improving the display effect of the display screen.

[0027] In some preferred embodiments, a viscose 170 is provided on the top of the circular tube 140. The viscose 170 is a circular ring structure. The shading foam 160 is fixed to the top of the circular tube 140 by the viscose 170, which can facilitate the fixation of the shading foam 160 and improve assembly efficiency.

[0028] Furthermore, the back panel 100 and the circular tube 140 are integrally formed. On the one hand, this can avoid the formation of a gap between the back panel 100 and the circular tube 140, thereby preventing light leakage. On the other hand, it can reduce the number of assembly steps between the back panel 100 and the circular tube 140, thereby reducing production costs. At the same time, it can also improve the structural strength of the display screen and increase its service life.

[0029] Furthermore, the edge of the back panel 100 is raised to form a support member 150, so that the support member 150 encloses the edge of the back panel 100 to avoid light leakage. At the same time, it is convenient for the back panel 100 and the support member 150 to be integrally formed, thereby improving the overall structural strength.

[0030] In some preferred embodiments, at least one brightness enhancement sheet 180 is provided between the diffuser plate 120 and the DBEF sheet 130. The brightness enhancement sheet 180 can increase the display brightness of the light. On the one hand, it can improve the display effect of the display screen. On the other hand, it can reduce the output power of the light board 110 and reduce energy consumption.

[0031] In some preferred embodiments, the lamp board 110 includes a PCB board 190 and a plurality of LED lamp beads 200 connected to the PCB board 190. The LED lamp beads 200 have the advantages of small size, light weight, fast response time, low energy consumption, and long service life, which greatly improve the stability of the display screen. The PCB board 190 can control the luminous power of each LED lamp bead 200, so that the lamp board 110 can perform zone dimming. Specifically, the brightness of the LED lamp beads 200 around the circular tube 140 can be adjusted to reduce the impact of the circular tube 140 on the display screen, thereby improving the overall display effect of the display screen.

[0032] Furthermore, a thermal conductive adhesive 210 is provided between the PCB board 190 and the back panel 100. When the display screen is working, the LED lamp beads 200 and the circuits on the PCB board 190 will emit a certain amount of heat. The heat is transferred to the back panel 100 through the thermal conductive adhesive 210, and then transferred to the external environment through the back panel 100. Thus, the heat dissipation performance of the display screen can be improved, the normal use of the display screen can be ensured, and the service life of the display screen can be increased.

[0033] In some preferred embodiments, a reflective sheet 220 is provided on the top of the PCB board 190, and the reflective sheet 220 is provided with a plurality of air-avoiding holes, which are used to avoid the LED lamp beads 200. After the light from the LED lamp beads 200 enters the diffuser plate 120, part of the light is emitted from the top surface of the diffuser plate 120, and part of the light is emitted from the bottom surface of the diffuser plate 120. The light emitted from the bottom surface of the diffuser plate 120 is reflected by the reflective sheet 220 and emitted from the top surface of the diffuser plate 120, thereby improving the utilization rate of light and improving the display brightness of the display screen.

[0034] Furthermore, a reflective strip 230 is provided on the inner wall of the support member 150 , and the reflective strip 230 can reflect the light irradiated onto the inner wall of the support member 150 , thereby further improving the utilization rate of the light.

[0035] In some preferred embodiments, a middle iron frame 240 is provided on the top of the support member 150. The middle iron frame 240 is used to limit the top of the DBEF sheet 130. On the one hand, the DBEF sheet 130 can be fixed to provide a solid support for the entire backlight assembly, thereby improving the stability and reliability of the display screen during use. Moreover, it can also protect the internal parts of the backlight assembly from external impacts. On the other hand, it can seal the gap between the DBEF sheet 130 and the support member 150 to prevent light leakage from the display screen.

[0036] Furthermore, an edge glue 250 is provided on the outer periphery of the middle iron frame 240. Specifically, the edge glue 250 is a single-sided glue, which is used to fix the middle iron frame 240 on the support member 150, thereby facilitating the disassembly and assembly of the middle iron frame 240.

[0037] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
