The size of the mounting substrate 1 specifically refers to the area of the mounting surface of the mounting substrate 1 for connecting the display module 2; the size of the display module 2 specifically refers to a display area of the display module 2 capable of displaying images.

In the existing display screen, each display module 2 is usually installed on a box body with better strength and flatness, and the technicians in the field generally have the inherent idea that each display module 2 must be supported and connected through the box body. However, in order to reduce the manufacturing cost of the display panel, it is necessary to improve each part of the display panel in a light weight manner. Although the traditional box body has a plurality of advantages, the box body can be replaced by only one connecting plate which is much smaller than the size of the display module, the box body structure which is larger in structure and higher in cost is omitted, the mounting substrate 1 is lighter and thinner than the box body, the material consumption is less than that of the box body, the manufacturing is simpler, the screen surface flatness of the display screen can be effectively guaranteed, and the display effect of the display screen is guaranteed; the manufacturing cost of the mounting substrate 1 is also significantly lower than that of the case, which is more favorable for reducing the overall cost of the display screen.
