The invention discloses a printed circuit board, comprising a circuit board, an electronic component arranged on a first surface of the circuit board, a first connecting finger and a second connectingfinger arranged on a second surface and a first surface of the circuit board, respectively. The first connecting finger includes a plurality of first contact points, and the second connecting fingerincludes a plurality of second contact points one-to-one corresponding to the first contact points, the corresponding first contact points and the second contact points having the same electrical structure,wherein a first connecting finger positioned on the opposite surface of the electronic component is used for binding with an external device in the flat display module, and a second connecting finger positioned on the same side of the electronic component is used for binding in the bent display module. The printed circuit board of the invention can be used for a flat display module and a bent display module, and the invention also discloses a display module comprising the printed circuit board.
Description
technical field [0001] The invention relates to the field of liquid crystal display, in particular to a printed circuit board and a display module. Background technique [0002] There are mainly two types of display module structures for existing liquid crystal display panels, one is a flat type display module (flat type), and its front view is as follows: figure 1 As shown, the left view is as figure 2 As shown, the printed circuit board 03 is arranged under the display panel 01, and the two ends of the flat flexible circuit board 02 (FPC) are respectively electrically connected to the terminal on the edge of the display panel 01 and the gold finger 031 on the printed circuit board 03 (PCB). sexual connection. The other is a bend type display module (bend type), its front view is as follows image 3 As shown, the left view is as Figure 4 As shown, the printed circuit board 03 is placed on the back of the display panel 01 , and the U-shaped flexible circuit board 02 el...
