Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display module FPC, in particular to a ZIF connector structure of the display module FPC. Background Art
[0002] AMOLED is widely used in smartwatch projects due to its bright display, high contrast and small screen. Smartwatches are becoming more and more comprehensive, integrating touch, display, NFC payment and other functions. Since smartwatches are consumer products, cost is also a key consideration, so the connectors are mainly ZIF connectors. However, due to the limited space of smartwatches, it is difficult to insert FPC into ZIF connectors. As a result, FPC sometimes cannot be inserted into the connector correctly or properly, resulting in various poor connections and poor displays. The difficulty in operation can easily lead to damage to the ZIF connector during connection, greatly increasing the cost of smartwatches. Utility Model Content

[0026] like Figure 1-3As shown, a ZIF connector structure of a display module FPC includes: a display screen 1, a touch FPC2 and a display FPC4; the top of the display screen 1 and the touch FPC2 are connected to each other through a metal PIN; a ZIF connector 42 is provided on the right side of the front of the display FPC4, and a PI film layer 43 is provided on the back of the front of the display FPC4; the length of the PI film layer 43 is between 15mm±1.0mm. It should be noted that the length of the PI film layer 43 is extended compared with the original design, so that its length is greater than the length of the ZIF connector 42, so that when the staff connects the ZIF connector 42 to the display mainboard, they only need to operate the longer end of the PI film layer 43.
[0027] like Figure 1-3 As shown, in one embodiment, the PI film layer 43 is disposed on the back of the ZIF connector 42 on the right side of the front of the display FPC 4, and the PI film layer 43 corresponds to the ZIF connector 42. The shape and size of the front of the PI film layer 43 are the same as the shape and size of the front of the right part of the display FPC 4. It should be noted that the PI film layer 43 can be completely attached to the block on the right side of the display FPC 4.
[0028] like Figure 1-3 As shown in one embodiment, an electronic component 41 is arranged on the left side of the front of the FPC 4. It should be noted that a heat dissipation component is arranged at the back of the electronic component 41 on the FPC 4.
[0029] like Figure 1-3 As shown, in one embodiment, a COFIC is provided at the center of the front of COF3, and a reinforcing glue is provided at the connection between COF3 and the display screen 1. A reinforcing glue is provided at the connection between the touch FPC2 and the display screen 1, and an electronic component area is provided at the front of the touch FPC2. It should be noted that this design can protect the connection between COF3 and the touch FPC2 when they are bent to the back of the display screen 1, preventing the connection from breaking.
[0030] like Figure 1-3 As shown, in one embodiment, a gold finger identification strip 44 is provided on the right side of the PI film layer 43, and the width of the front side of the gold finger identification strip 44 is between 0.5mm±0.2mm. The gold finger identification strip 44 divides the PI film layer 43 into two parts, wherein the front side of the area close to the ZIF connector 42 is 5.00mm±0.5mm in length, and the front side of the other side is 10.00mm±0.5mm in length. It should be noted that the shorter PI film layer 43 is fixedly connected to the display FPC4, while the longer part of the PI film layer 43 is not fixedly connected, so it can be lifted as needed.
[0031] like Figure 1-3As shown in the figure, in one embodiment, the PI film layer 43 is provided with auxiliary handles 45 at the top and bottom away from the ZIF connector 42, and the front of the auxiliary handle 45 is shaped like a vertically long hollow ring. It should be noted that the auxiliary handle 45 can facilitate the operation of the staff, so that the ZIF connector 42 can be driven to connect with the display module motherboard without pinching the PI film layer 43.
[0032] like Figure 1-3 As shown, in one embodiment, the area of the touch FPC 2 and the display FPC 4 is smaller than the area of the front of the display screen 1. It should be noted that the display FPC 4 needs to be folded before it can be bent to the back of the display screen 1.
[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
