Abstract
The invention discloses a display panel, a display device and a manufacturing method of the display panel. After a chip-on-chip film is attached to a frame on a side of the display surface away from a display substrate by using an insulating adhesive, and then the insulating adhesive is passed through the display substrate and the insulating adhesive respectively. And the conductive material in the multiple connection holes of the chip-on-chip film to realize the connection between the signal line at the display surface frame of the display substrate and the connection terminal arranged on the side of the chip-on-chip film away from the display substrate, so it not only saves the need to bend the Pad. The folding process is adopted, and there is no Pad bending area at the frame of the display panel, so that the lower frame of the display panel can be made narrower.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a method for manufacturing the display panel. Background technique [0002] With the continuous advancement of display technology, display panels are more and more widely used in display products. Display products with narrow bezels (Narrow Bezel) have attracted a large number of consumers because they can enable users to obtain a better viewing experience. [0003] Currently, Pad Bending is the only solution to realize a display product with a narrow lower bezel. However, there are many problems with the yield rate of the display products made by the Pad bending process, for example, as figure 1 As shown, cracks occur in the inorganic insulating layer in the Pad bending region P, which will lead to display failure. In the prior art, a mask (Mask) process is added to remove the inorganic insulating layer in the Pad bending area P;...
