Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display module structures, in particular to a direct-type liquid crystal display module structure for improving the heat dissipation efficiency of an LED lamp panel. Background Art

[0002] The LED light panels of the existing conventional direct-type LCD display module structure are all installed in a structural frame with a metal base plate. The LED light panel is in direct contact with the metal base plate structure. The heat generated during operation is transferred to the metal base plate structure, and then dissipated outward through the metal base plate structure, thereby achieving the effect of cooling the LED light panel. However, in order to increase the strength, some metal base plate structures have an external convex mold design, resulting in a corresponding concave area inside, which makes it impossible for the LED light panel to completely contact the metal base plate, and some areas are suspended in the air, resulting in very low heat dissipation efficiency. In addition, some flat metal base plate structures cannot be completely flat due to the strength of the metal itself, which has a certain impact on the heat dissipation efficiency of the LED light panel. If the heat dissipation effect is not ideal, the service life of the LED lamp beads will be reduced.

[0003] Therefore, in order to solve this problem, there is a need to improve the structure of a direct-type liquid crystal display module that can improve the heat dissipation efficiency of an LED light panel. Utility Model Content
