Description

Borderless display module assembly and mobile terminal Technical Field The utility model relates to the technical field of display, in particular to a borderless display module and a mobile terminal. Background With the continuous progress of technology, the importance of display technology in the field of electronic devices is increasingly prominent, and especially borderless display products have become the mainstream trend of the market. Consumers have increasingly higher requirements on the appearance design and the display effect of display products, and extremely high cost performance becomes one of the key factors of market competition. However, the existing borderless display module structure still has a plurality of defects in meeting the market demand. At present, two solutions of borderless display modules are mainly available on the market, but there are some obvious limitations that one is to use a plastic frame to support a liquid crystal panel and seal an optical cavity. Although the structural requirement of the display module can be met to a certain extent, the die cost of the rubber frame is high, and the material cost is directly increased, so that the overall manufacturing cost of the product is increased. The other is an F-shaped folded structure of the metal backboard, and the assembly of the display module is realized by matching with a silica gel strip and a spot black gel. Although the use of materials is reduced to a certain extent, the procedures are complex, and the procedures of adding the silica gel strips and dispensing the black gel are required, so that the production cost is increased, and the production period is prolonged. Therefore, how to solve the problem of high production cost of the existing borderless display module is a problem to be solved by those skilled in the art. Disclosure of utility model Therefore, the utility model aims to provide a borderless display module, which has simple structure and low production cost. Another object of the present utility model is to provide a mobile terminal including the above borderless display module, which has low production cost. In order to achieve the above object, the present utility model provides the following technical solutions: A frameless display module comprises a back plate, wherein the back plate is provided with a flanging structure for supporting a liquid crystal panel, the flanging structure comprises a flanging for supporting the liquid crystal panel, the edge of the flanging away from the back plate is provided with a turnover flanging, the flanging and the flanging are in transition through a round corner structure, the flanging and the flanging are arranged in parallel, the corners of the back plate are mutually overlapped with two flanging structures, and the flanging of one flanging structure is overlapped with the flanging of the other flanging structure, so that a closed optical cavity is formed among the back plate, the liquid crystal panel and the flanging structures. Preferably, the outer surface of the flanging is provided with a waterproof coating and an antistatic coating. Preferably, the back plate is integrally formed with the flange structure.
