Description

Display module assembly, protection sticky tape and electronic equipment Technical Field The application relates to the technical field of display, in particular to a display module, a protective adhesive tape and electronic equipment. Background Before the finished product shipment, the display module needs to be attached with a protective tape on the circuit board of the display module, and the protective tape can prevent water vapor and dust from contacting the circuit board, so that the circuit board is prevented from being corroded. The electronic components are arranged on the circuit board and protrude out of the surface of the circuit board, and the electronic components can bring stamping problems to the display module and influence the display effect of the display module. Disclosure of Invention The embodiment of the application provides a display module, a protective adhesive tape and electronic equipment, the display module can avoid the protection tape from extruding electronic components, thereby avoiding the problem of stamping of the display module. In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a display module for an electronic device, where the display module includes a circuit board, an electronic component, and a protective tape. The circuit board comprises a first surface, wherein the first surface is provided with a first area and a second area arranged around the first area. The electronic component is arranged in the first area. The protective tape comprises a first sealing part and a second sealing part which are arranged in a split mode, wherein the first sealing part covers the electronic component, and the second sealing part covers the second area. When the protective tape is connected to the first surface, the protective tape moves towards the circuit board under the drive of the pressing jig, the first sealing part contacts the electronic component first, and at least part of the first sealing part is connected to the electronic component. Because the first sealing part and the second sealing part are arranged in a split way, the first sealing part moves relative to the second sealing part in the process that the protective adhesive tape continuously moves towards the circuit board, so that the protective adhesive tape is prevented from being elastically deformed at the electronic component. The protection tape continues to move towards the circuit board, the first sealing part is connected to the first area through the first adhesive layer, and the second sealing part is connected to the second area through the second adhesive layer. Therefore, the protective adhesive tape is connected to the circuit board and does not elastically deform, the protective adhesive tape can not apply extrusion force to the electronic components, the problem of stamping of the display module is avoided, and the display effect of the display module is improved. In one possible implementation manner of the first aspect, the first sealing portion includes a first connection portion, a second connection portion, and a redundancy portion. The first connecting part is arranged around the electronic component and connected to the first surface, and the second connecting part covers the surface of the electronic component, which is opposite to the first surface. The first end of the redundant part is connected to the first connecting part, the second end of the redundant part is connected to the second connecting part, the length from the first end to the second end of the redundant part is a first length, and the first length is greater than or equal to the linear distance from the first end to the second end. Therefore, after the protective tape is connected to the first surface, the electronic component is sealed between the protective tape and the circuit board, the protective tape plays a role in protecting the electronic component, moisture and dust are prevented from contacting the circuit board and the electronic component, and the reliability of the circuit board and the electronic component is improved. After the redundant part is connected with the first connecting part and the second connecting part, the redundant part has a length allowance, the redundant part does not elastically deform, and the redundant part is in a loose state. Because the protection sticky tape is connected between first connecting portion and second connecting portion with the help of redundant portion, the protection sticky tape can not produce elastic deformation because of electronic components protrusion in first surface, and the protection sticky tape is in the relaxation state that does not take place elastic deformation, and the protection sticky tape just also can not apply the extrusion force to electronic components, and electronic components department can not have t
