Description

Technical Field

[0001] The present invention relates to the technical field of displays, and in particular to a touch module enclosing type fixing structure and a fixing method thereof. Background Art

[0002] At present, common large-scale displays on the market, such as desktop displays, indoor and outdoor public displays or electronic whiteboards, are gradually equipped with touch functions. The touch module needs to be fixed on the front of the display panel so that the touch points can be matched with the screen display to meet the touch control experience.

[0003] In the prior art, the touch module is fixed on the surface of the display panel in two ways: frame pasting and full pasting. Full pasting is to fill the gap between the touch module and the display panel with water glue and fix them, while frame pasting is to stick the touch module on the four sides of the display panel with double-sided tape. However, there is a problem with the existing frame pasting method, that is, the double-sided tape on the four sides of the display panel is pasted on the iron parts of the display panel frame, and a certain pasting area and adhesive strength are required to support the weight of the touch module. However, the narrowing of the display panel frame is a market development trend, and the strength of the frame pasting will inevitably decrease with the narrowing of the frame, which is difficult to adapt to the development needs of narrow-frame or frameless displays. Summary of the invention

[0004] The object of the present invention is to provide a touch module enveloping fixing structure and a fixing method thereof which have reasonable design, simple structure and fixing strength not limited by the narrowing of the frame.

[0005] To achieve the above first object, the present invention adopts the following technical solutions:

[0006] The touch module wrapped fixing structure of the present invention is used to fix the touch module with a touch sensing film on the front side of the display panel, and includes a touch sensing film, and the touch sensing film is extended outward to form a plurality of edges corresponding to the edges of the display panel. When the touch sensing film is covered on the front side of the display panel, the plurality of edges are bent toward the back side of the display panel and wrapped around the side frame and the back panel edge of the display panel, and are fixed by fasteners.

[0007] Preferably, the fastener is one or more of double-sided tape, glue, screws and buckles.

[0008] Preferably, when the fastener is a double-sided tape or glue, the double-sided tape or glue is provided at the contact areas between the plurality of edges and the display panel.

[0009] Preferably, when the fasteners are screws, the screws are arranged on the back of the display panel to lock and fix the plurality of edge covers to the edge of the back plate of the display panel.

[0010] To achieve the above second purpose, the present invention adopts the following technical solutions:

[0011] The touch module encapsulating fixing method of the present invention adopts the above-mentioned touch module encapsulating fixing structure to fix the touch module having the touch sensing film on the front side of the display panel. The method comprises the following steps:

[0012] 1) Extending the edges of the touch sensing film of the touch module outward to form multiple edges;

[0013] 2) Attach the cover of the touch module to the outer surface of the touch sensing film;

[0014] 3) Covering the inner surface of the touch sensing film on the front of the display panel;

[0015] 4) Adhere adhesive material to one or more positions of the side frame and the edge of the back panel of the display panel;

[0016] 5) The plurality of edges are bent and folded toward the back of the display panel to cover the side frames and the edge of the back plate of the display panel, so as to fix the touch module and the display panel into one.

[0017] Preferably, the cover plate in step 2) is made of glass, PC or PMMA material.

[0018] Preferably, the adhesive material in step 4) is double-sided tape or glue.

[0019] Furthermore, in step 5), after the multiple edge covers are bent and folded toward the back of the display panel to cover the side frames and the back panel edge of the display panel, multiple screws are used to lock and fix the multiple edge covers to the back panel edge of the display panel.

[0020] The present invention adopts the above technical scheme, by extending the touch sensing film of the touch module outward on the original size to form multiple edges, allowing the multiple edges to be bent and folded along the appearance of the display panel, and adhering and fixing them with double-sided tape or glue or other adhesive materials in the contact areas of the appearance parts of the display panel such as the side frame and the back plate, or further locking and fixing them with screws, so that the extended edges can be used to strengthen the bonding strength with the back of the display panel, so that it has sufficient fixed adhesion for support, and is not affected by the market trend of narrow frame or even frameless display panels.
