Problems solved by technology
[0002] In recent years, the splicing display module is an important research direction for researchers. The splicing display module transmits the signal line of one of the display panels to the Another display panel can omit the chip-on-chip integrated circuit at the splicing point, reduce the driving cost, realize seamless splicing, and solve the display problem caused by asynchronous signals. However, due to the rigid substrate material of the display panel , it is easy to have a step difference or a gap at the splicing point, resulting in disconnection of the connecting line at the splicing point, which affects the display effect of the display module

The embodiment of the invention discloses a display module, a manufacturing method thereof and a display device. The display module comprises at least two display panels spliced with each other and a plurality of connecting lines, each display panel comprises a rigid substrate and a flexible substrate located on the rigid substrate, the flexible substrate is in lap joint with the rigid substrate of the adjacent display panel, one connecting line is electrically connected with signal lines of the two adjacent display panels, and the connecting lines are electrically connected with signal lines of the two adjacent display panels. Any connecting line at least comprises a first part which is positioned on one side, far away from the rigid substrate, of the flexible substrate; according to the display module, the characteristic of good coverage of the flexible substrate is utilized, the splicing position of the rigid substrates is covered with the flexible substrate, and the connecting lines are arranged on the flexible substrate, so that the breakage probability of the connecting lines at the splicing position of the rigid substrates is reduced, and the display effect of the display module is improved.
Description
technical field [0001] The invention relates to the field of display, in particular to a display module, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, the splicing display module is an important research direction of researchers. The splicing display module transmits the signal line of one display panel to the splicing position of two adjacent display panels by setting multiple connecting lines. Another display panel can not only omit the chip-on-chip film on the splicing part, reduce the driving cost, realize seamless splicing, but also solve the display problem caused by the asynchronous signal. However, due to the rigid substrate material of the display panel , It is easy to have a step difference or gap at the splicing place, which will cause the connection line to break at the splicing place, which will affect the display effect of the display module. [0003] Therefore, there is an urgent need for a display module...
