Compared with the prior art, the present invention electrically connects the input pins of each controller to the output pins of the upper level controller, so that the control signal sent by the driving module can be transmitted to each backlight partition step by step, which simplifies the circuit layout of the substrate and reduces the cost of the substrate. However, the existing LED backlight display modules have low heat dissipation efficiency. As the temperature of the LED module increases, the color may become more red or yellow, which affects the color accuracy and consistency of the display. When working at high temperatures for a long time, the luminous performance of the LED will gradually decrease until it eventually fails. For this reason, we propose an LED backlight display module with active heat dissipation function. Utility Model Content

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is an LED backlight display module with active heat dissipation function, including a shell 1, on which a plurality of equidistantly arranged display units are arranged, the display units include a mounting member 101, the interior of the mounting member 101 is hollow, the mounting member 101 is mounted on the shell 1 by gluing, a circuit board 102 is mounted on the mounting member 101, and a display module 103 is mounted on the circuit board 102; a storage cavity 201 is arranged inside the shell 1, and the storage cavity 201 is filled with heat exchange liquid, a plurality of conducting holes 202 are opened on the shell 1, and connecting holes 203 are opened on the mounting member 101, and the connecting holes 203 are respectively connected with the conducting holes 202, a heat conducting plate 204 is fixedly installed on the top of the mounting member 101, the heat conducting plate 204 extends to the circuit board 102 and contacts with the circuit board 102, a plurality of evenly distributed heat dissipation grooves 205 are opened on the circuit board 102, and the heat dissipation grooves 205 run through the circuit board 102. A plurality of mounting holes are provided on the circuit board 102 , and protective pads are provided at the corners of the circuit board 102 and the display module 103 .

[0024] By filling the storage cavity 201 with heat exchange liquid, the temperature of the heat exchange liquid is relatively low, and the heat exchange liquid enters the inner cavity of the mounting component 101 through the conducting hole 202 and the connecting hole 203, and the heat conducting plate 204 is immersed in the heat exchange liquid in the inner cavity of the mounting component 101. The heat on the display module 103 can enter the heat conducting plate 204 through the heat dissipation groove 205, and the heat conducting plate 204 can absorb the heat discharged by the display module 103. The heat on the heat conducting plate 204 can be absorbed by the heat exchange liquid, so that the heat generated by the display module 103 when working is absorbed by the heat exchange liquid, and the heat dissipation efficiency of the display module can be improved.

[0025] The sides of the housing 1 are provided with heat dissipation fins 301, which extend into the inner cavity of the housing 1. When the heat exchange liquid works for a long time, the temperature of the heat exchange liquid itself will continue to rise, so the heat in the heat exchange liquid can be absorbed by the heat dissipation fins 301 and transferred to the outside through the heat dissipation fins 301, thereby accelerating the heat transfer of the heat exchange liquid to the outside and accelerating the rate of decrease of the temperature of the heat exchange liquid.

[0026] A heat conducting member 302 is disposed in the internal cavity of the mounting member 101, and holes 303 are provided on both sides of the mounting member 101, and the holes 303 penetrate the mounting member 101. Heat conducting blocks 304 are fixedly installed in the holes 303, and both ends of the heat conducting member 302 are connected to the heat conducting blocks 304 on both sides, and a micro fan 305 is installed in the hole 303 on one side. The heat conducting member 302 is arranged in a spiral shape to increase the contact area with the heat exchange fluid and accelerate heat absorption.

[0027] The heat in the heat exchange liquid is absorbed by the heat conductive member 302, and the heat on the heat conductive member 302 is then absorbed by the heat conductive blocks 304 on both sides. The low-temperature air is introduced into the channel 303 through the micro fan 305. The low-temperature air contacts the heat conductive blocks 304 in the channel 303, thereby taking away the heat on the heat conductive blocks 304, which can further accelerate the rate of temperature reduction of the heat exchange liquid, thereby improving the heat dissipation efficiency of the display module.

[0028] Working principle: The heat on the display module 103 can enter the heat conducting plate 204 through the heat dissipation slot 205. The heat conducting plate 204 can absorb the heat discharged by the display module 103. The heat on the heat conducting plate 204 can be absorbed by the heat exchange liquid, thereby using the heat exchange liquid to absorb the heat generated when the display module 103 is working. The heat in the heat exchange liquid is absorbed by the heat conducting member 302, and the heat on the heat conducting member 302 is then absorbed by the heat conducting blocks 304 on both sides. The low-temperature air is introduced into the channel 303 through the micro fan 305. The low-temperature air contacts the heat conducting blocks 304 in the channel 303, thereby taking away the heat on the heat conducting blocks 304, which can further accelerate the rate of temperature reduction of the heat exchange liquid, thereby improving the heat dissipation efficiency of the display module. The heat in the heat exchange liquid can be absorbed by the heat dissipation fins 301 and conducted to the outside through the heat dissipation fins 301, thereby accelerating the heat transfer of the heat in the heat exchange liquid to the outside and accelerating the rate of temperature reduction of the heat exchange liquid.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
