Problems solved by technology

However, the flatness of the double-sided adhesive 50a is relatively low, and it is easy to wrinkle. Therefore, it is easy to be compressed and thinned after being subjected to pressure during assembly, reliability test, etc., so that the entire welding space 70 becomes smaller, and the solder 60 is easy to push against the LCD. The bottom surface of the module 40 will cause quality problems such as bright spots and bright blocks in the LCD module 40, and even cause the LCD module 40 to be distorted and deformed during the drop test, resulting in serious malfunctions such as LCD white screen and cracks.

Abstract

The invention discloses a display module. The display module comprises a glue frame and an LCD (liquid crystal display) module, wherein the glue frame is a rectangular framework which comprises an upper frame, a lower frame and two side frames which are used for connecting the upper frame and the lower frame; the bottom surface of each side frame of the glue frame is provided with a sinking part; and each sinking part is used for arranging a double-faced adhesive tape. The invention also provides a mobile communication device comprising the display module. Through the mode, according to the display module and the mobile communication device, the welding space stability can be ensured, and thus the display quality of the display module can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a display module and mobile communication equipment. Background technique [0002] In order to save costs, the technology of soldering LCD on the back is commonly used in some low-priced mobile phones. Specifically, the technology of soldering the LCD on the back is to weld the LCD module and the PCB board together by soldering tin on the back of the LCD module. [0003] Among them, pre-positioning is firstly performed, and double-sided tape is usually used for pre-positioning, and the double-sided tape is usually set on the plastic frame. Please refer to figure 1 , figure 1 is a structural schematic diagram of a display module in the prior art, such as figure 1 As shown, double-sided adhesive tapes 50a and 50b are respectively provided on the two side frames 101 and 102 of the adhesive frame 10 in the display module 100 , and the length of the double-sided adhes...
