[0006] Further, the display unit is a liquid crystal display unit, the liquid crystal display unit comprises a liquid crystal display glass, and the binding connector is bound and connected with the single-layer area of the liquid crystal display glass.

[0007] Further, the display module further comprises a backlight module, which is stacked on the bottom layer of the display unit.

[0008] The utility model further provides a kind of electronic equipment, including the display module of above-mentioned middle and large size.

[0009] Further, the electronic equipment further comprises a housing and a device mainboard, the housing is arranged in the device mainboard, and the FPC of the display module is electrically connected with the mainboard.

[0010] With the above scheme, the beneficial effects of the utility model are as follows: the display module binding efficiency can be improved, the expansion of FPC binding can be improved, the alignment deviation can be avoided, and the quality of display module products can be improved. BRIEF DESCRIPTION OF DRAWINGS
