In this embodiment, the first end 110A is taken as the lower end of the display module 110, the second end 110B is taken as the upper end of the display module 110, and the first side 110C and the second side 110D are respectively taken as the left side and the right side of the display module 110 for illustration.
As shown in fig. 1, the connection portion 111 is located at the first end 110A of the display module 110, and particularly, adjacent to the effective display area (AA area) 112 of the display module, it should be understood that, in general, the connection portion 111 is located at an area outside the Polarizer (POL)113 and the Color Filter (CF)118, but there may be some circuit structures below the connection portion, such as a Thin Film Transistor (TFT)115, and the flexible circuit board 120 extends toward the first side 110C and/or the second side 110D of the display module 110. That is, the connection portion 111 is located at the lower end of the display module 110, and the flexible circuit boards 120 connected to the connection portion 111 extend in the left and right directions of the display module 110, respectively.
In the related art, the width of the display panel is the sum of the width of the connection portion 111 and the width of the mounting module electrically connected to the connection portion 111.
In the technical solution of the present embodiment, the flexible circuit board 120 is used to be bound (bound) with the connecting portion 111 of the display panel, so that the frame width of the display panel is the width of the connecting portion 111.
Through tests, the frame width of the display panel adopting the related art is about 4.5 mm, and after the technical scheme of the embodiment is adopted, the frame width is reduced to about 2 mm, so that the frame width can be obviously reduced.
In this embodiment, the flexible circuit board 120 is electrically connected to the connecting portion 111 of the display module 110 to transmit signals, and meanwhile, the extending direction of the flexible circuit board 120 is toward the side of the display panel, so that the excessive space occupying the end of the display panel can be avoided, and the reduction of the frame width of the display panel is realized.

Optionally, the conductive sheet 114 is located on one side of the connection portion 111 close to the light exit side of the display module 110, and one end of the flexible circuit board 120 away from the connection portion 111 is turned over to one side of the display module 110 facing away from the light exit side. Through overturning the flexible circuit board 120 to the back of the display module 110, the front space of the display module 110 can be prevented from being occupied, thereby being beneficial to reducing the width of the frame.
In an optional embodiment, the number of the flexible circuit boards 120 is two, and the two flexible circuit boards 120 extend to the first side edge 110C and the second side edge 110D of the display module 110, so as to avoid the circuits on the flexible circuit boards 120 from being too concentrated, and enable the distribution of the circuits to be more uniform.
