Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display modules, in particular to a waterproof structure of a liquid crystal display module. Background Art

[0002] The structure of the liquid crystal display module includes a liquid crystal panel and a backlight module. The backlight module includes a rubber frame, and LED components and various optical panels housed in the rubber frame. When assembling the liquid crystal display module, the liquid crystal display panel is arranged above the backlight module, and is in contact with and bonded to the rubber frame. The liquid crystal display panel generally includes a first substrate, a second substrate, and a liquid crystal arranged between the first substrate and the second substrate. The corners of the liquid crystal display panel are in contact with the rubber frame. An existing waterproof structure of a liquid crystal display module is bonded and packaged by glue during packaging, and long-term use may result in poor waterproof sealing. Therefore, we introduce a new waterproof structure of a liquid crystal display module. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By aligning and installing the mounting blocks in the two limit grooves, the two clamping blocks are clamped in the two clamping grooves by the elastic contraction and elastic reset of the two first springs, so that the waterproof film is installed in front of the display screen. After installation, the waterproof rubber strip is clamped in the sealing groove to prevent rainwater from entering, which solves the problem of poor waterproof sealing performance in the traditional packaging that may occur after long-term use by glue. At the same time, the installation is fixed;

[0013] 2. By pulling the handle upward, the five movable rods are driven to move upward. At this time, the elastic force of the five second springs contracts. Then, by installing the fixing block in the fixing frame and releasing the handle, the elastic force of the five second springs can be used to reset the card in the fixing groove, thereby facilitating the fixation of the entire display module and facilitating operation.
