When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Referring to fig. 1 and 2, there is shown an electronic device 200' in the related art, in which a display module 100' of the electronic device 200' is packaged using a COP packaging process, the display module 100' has a flexible display screen including a display portion 11' and a connection portion 12', the display portion 11' has a function of displaying an image, and the connection portion 12' has a function of electrically connecting the display portion 11' with other devices (e.g., a circuit board, a chip).

With continued reference to fig. 1 and 2, the connection 12' includes a first connection region 121' and a second connection region 122' that are connected. The first connection area 121 'is directly connected to the display portion 11', and by setting the first connection area 121', the display portion 11' can be extended to a certain extent, so that edge light leakage of the electronic device in the use process is avoided, a display effect is ensured, the first connection area 121 'is subsequently blocked by the coated black ink, and the first connection area 121' is not observed when a user views from the outside.

Fig. 2 exemplarily illustrates that the first connection region 121 'is disposed at one side of the display part 11', and it is understood that the first connection region 121 'is also required to be disposed at the other three sides of the display part 11' having a rectangular shape to avoid light leakage, that is, black regions having a size n must be reserved for ensuring the display effect of the display part 11 'at four sides of the display part 11'. It should be noted that, in fig. 2, the bottom black edge size of the display module 100' may reach the limit size n (i.e. the size of the first connection region 121 ') in the prior art, and if the size of the first connection region 121' is smaller than n, the screen light leakage may occur.
