Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the present disclosure, the use of directional words such as "up, down, left, right, front, and back" in the case where no description is made to the contrary, refers to "up, down, left, right, front, and back" defined in a normal use state of the terminal device; in particular, reference may be made to fig. 1; use of directional words such as "inner and outer" refers to the inner and outer of a particular structural profile; the use of terms such as "first," "second," etc. are used merely to distinguish one element from another, and are not necessarily sequential or significant.

It should be noted that, in the process of the invention and creation, the inventor of the present disclosure finds that the ways of eliminating the static electricity of the display screen in the related art mainly include two types:

the first method comprises the following steps: the method is characterized in that a silver paste dispensing mode is adopted to connect C-Panel (a display screen protective layer, namely a protective layer 2 hereinafter) and Back-Prop (a display screen supporting layer, namely a supporting layer 1 hereinafter) on the Back of the Panel (the display screen), so that static conduction is realized, static on the Back-Prop is conducted to the C-Panel, and damage to the Panel is avoided. But the silver paste dotting process is complex and the raw material cost of the silver paste is high.

And the second method comprises the following steps: compared with the conventional C-Panel, the size of the periphery of the C-Panel is enlarged, so that the area of the C-Panel copper foil covering the Back-Prop is larger, and the C-Panel copper foil can be quickly transferred to the C-Panel copper foil when static electricity is generated on the Back-Prop due to friction, so that the static electricity is prevented from being accumulated on the Panel. However, since the C-Panel and the Back-Prop have certain pasting tolerances, if the size of the C-Panel is enlarged to a certain extent, the pasting precision of the C-Panel and the Back-Prop cannot be detected. In order to detect the attaching precision between the C-Panel and the Back-Prop, in the related technology, observing grooves which are constructed into concave notches are formed in the edges of the left side and the right side of the C-Panel and are used for observing the attaching precision between the C-Panel and the Back-Prop, if the edges of the left side and the right side of the Back-Prop are exposed in the observing grooves, the C-Panel and the Back-Prop reach the attaching precision, and if the edges of the Back-Prop do not appear in the observing grooves, the C-Panel and the Back-Prop do not reach the attaching precision. Therefore, the sticking precision of the C-Panel and the Back-Prop can be monitored, the size of the C-Panel can be enlarged, and the static electricity resisting capability of the Panel is improved.

However, if the observation grooves are disposed on the left and right edges of the C-Panel, the wires are routed around the Panel, and particularly, the GOA (Gate drive on Array, Gate drive integrated on Array) wires are routed on the left and right sides of the Panel, and the position of the observation groove is not covered by the copper foil in the C-Panel, which results in poor conductive effect. Based on this, in order to solve the technical problem, the inventors of the present disclosure have made the following modified design:

as shown in fig. 1 to 3, the present disclosure provides a display screen static electricity prevention assembly, which includes a support layer 1 and a protection layer 2, wherein the support layer 1 is configured to be disposed on a back surface of a display screen (not shown) to support the display screen, and the protection layer 2 is disposed on the back surface of the support layer 1 to eliminate static electricity generated by the support layer 1.

Further, the protective layer 2 and the support layer 1 have a certain bonding accuracy therebetween, and the bonding accuracy needs to be ensured when the both are bonded.
