Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display, and in particular to a novel liquid crystal display module. Background Art

[0002] Liquid crystal display technology has been widely used in various fields of our lives, such as PDAs, computer screens, and notebook screens. Liquid crystal display modules have many advantages such as thin body and power saving. However, since the LED light bar is placed on the inside of the back panel, a large amount of heat will be generated when the LED light bar is working. This heat is concentrated on the inside of the back panel and is difficult to dissipate effectively. Continuous high temperature will not only affect the normal operation of the light bar, but also easily cause the light guide plate to expand due to heat, seriously affecting the overall use effect and life of the liquid crystal display module. Therefore, the current field of liquid crystal display technology still needs further technical improvements. Summary of the invention

[0018] Reference Figure 1 and Figure 2 As shown, a novel liquid crystal display module proposed by the present invention includes a display mechanism, a heat dissipation mechanism and an LED light bar 3;

[0019] The display mechanism includes a back plate 11, a reflective sheet 12, a light guide plate 13, an optical film material 14, a plastic frame 15, a liquid crystal display panel 16 and an outer frame 17; the reflective sheet 12 is mounted on the back plate 11, the light guide plate 13 is mounted above the reflective sheet 12, the optical film material 14 is mounted above the light guide plate 13, the plastic frame 15 is sleeved on the back plate 11, the liquid crystal display panel 16 is mounted on the plastic frame 15 and is located above the optical film material 14, the outer frame 17 is sleeved on the plastic frame 15, and a light guide through hole 110 is provided on the side of the back plate 11 at a position corresponding to the light guide plate 13;

[0020] The heat dissipation mechanism includes a heat dissipation block 21, which is provided with a thermal through hole 211 and a mounting groove. The heat dissipation block 21 is installed on the rubber frame 15. The heat dissipation block 21 is located on one side of the mounting groove and abuts against the side of the back plate 11. The light guide through hole 110 is connected to the mounting groove, and the LED light strip 3 is installed in the mounting groove; the heat dissipation block 21 is located on both axially opposite sides of the thermal through hole 211 and abuts against the back plate 11. The back plate 11 is provided with a first ventilation hole 171 and a second ventilation hole 172, and the first ventilation hole 171 and the second ventilation hole 172 are both connected to the thermal through hole 211.

[0021] When the present invention is used, the light emitted by the LED light bar 3 is projected to the light guide plate 13 through the light guide hole 110, and the heat generated by the LED light bar 3 is transferred to the heat sink 21. The heat of the heat sink 21 directly contacts the air in the heat conduction hole 211, and the heat is transferred to the air. The first vent 171 and the second vent 172 cooperate with the heat conduction hole 211 to achieve the circulation of air in the heat conduction hole 211. The present invention has a simple structure, is easy to use, and has an excellent heat dissipation effect. The LED light bar 3 is installed on the outside of the back plate 11, which reduces the requirements for the thermal conductivity of the back plate 11 and increases the range of back plate material selection.

[0022] In this embodiment, the heat dissipation mechanism also includes a plurality of heat dissipation auxiliary devices;

[0023] The heat dissipation auxiliary device includes a plurality of mounting posts 221 . The mounting posts 221 are mounted in the heat-conducting through holes 211 . The mounting posts 221 can increase the heat dissipation area of ​​the present invention, thereby further improving the heat dissipation effect of the present invention.

[0024] In this embodiment, the heat dissipation auxiliary device also includes a heat dissipation column 222, a flow-assisting plate 223 and a gravity ball 224. The heat dissipation column 222 is provided with a flow storage chamber 225 and a mounting through hole. The mounting through hole passes through the flow storage chamber 225. The heat dissipation column 222 is rotatably mounted on the mounting column 221 through the mounting through hole. The heat dissipation column 222 can further increase the heat dissipation area of ​​the present invention. When in use, injecting a viscous liquid into the flow storage chamber 225 can reduce the rotation speed of the heat dissipation column 222 during position adjustment of the present invention, thereby improving the stability of the present invention during position adjustment.

[0025] The flow-assisting plate 223 is installed on the installation column 221 and is located in the flow storage cavity 225 . The flow-assisting plate 223 can further improve the stability of the heat dissipation column 222 when adjusting its position.

[0026] In the present embodiment, the heat dissipation column 222 is a triangular prism, and the gravity ball 224 is installed in the flow storage chamber 225. Since the heat dissipation column 222 can rotate, the triangular prism is coordinated with the gravity ball 224 to keep the triangular prism in an inverted triangle state, so that the heat dissipation column 222 can play the role of air diversion, thereby effectively improving the heat dissipation effect of the present invention.

[0027] In this embodiment, the cross-sectional area of ​​the first vent 171 gradually decreases in the direction away from the heat dissipation mechanism; the cross-sectional area of ​​the second vent 172 gradually decreases in the direction away from the heat dissipation mechanism. This method helps to reduce the possibility of dust falling into the thermal conductive hole 211 and promote air circulation.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
