Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display modules, in particular to the technical field of LCMs for improving use stability. Background Art

[0002] The connection between LCM and terminal equipment is usually achieved by adding a double-sided adhesive on the back of the backlight, so that the LCM is glued and fixed to the terminal equipment. This connection method is low-cost and easy to assemble, and is a commonly used connection method. However, in this connection scheme, the double-sided adhesive will decrease in viscosity after long-term use or in a relatively harsh environment, causing the LCM to shift or loosen on the application equipment. In addition, the double-sided adhesive on the back of the LCM is not conducive to the removal of the LCM, and the removal is likely to damage the structure of the backlight and affect the display effect.
