Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.
It is to be understood that the terms "length," "width," "upper," "lower," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, and are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present application.
Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
It should be noted that, the touch-control integrated machine may be understood as a display device that can be controlled by touching. The touch integrated machine generally comprises a system main board and a touch main board, wherein the system main board is mainly used for controlling system functions of the display device, and the touch main board is connected between the system main board and a touch screen and is used for processing and sending touch related signals.
In the related art, a system motherboard and a touch motherboard in a touch integrated machine are mutually independent structures; the system main board and the touch main board are arranged at different positions of the integrated machine, each main board needs to reserve a corresponding installation space on the touch screen and is fixed in the installation space through the fixing assembly, and the different main boards need to be respectively provided with a heat dissipation structure and a packaging structure; the structure wastes the installation space, greatly occupies the available space of the touch control integrated machine, and has complicated installation steps.
Further, since the system motherboard and the touch motherboard in the conventional display device are separately installed at different positions, the system motherboard and the touch motherboard need to be connected through pins or other types of connectors to realize data transmission between the system motherboard and the touch motherboard. But the signal transmission loss between the system motherboard and the touch motherboard is large, the signal transmitted from one to the other becomes weak and the signal becomes unstable. Meanwhile, because the transmission path between the system main board and the touch main board is longer, the signal transmission also has larger delay, the problems of mode and mode switch and shutdown time sequence can be caused, and the system is seriously down.
The application is based on the improvement of the related main board structure, the display device and the electronic equipment.
