Abstract

The embodiment of the invention provides a display module, a binding method thereof and a display device. The display module comprises a display panel and a driving structure, and the display panel and the driving structure are connected in a binding mode. The display panel comprises a first test mark, and the driving structure comprises a second test mark. The first test mark and the second test mark are used for testing the expected expansion rate of the display panel before the display panel and the driving structure are bound. The process temperature of the binding process can be determined according to the expected expansion rate, and binding deviation of the display panel and the driving structure is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module, a binding method thereof, and a display device. Background technique [0002] When manufacturing a display panel, usually a plurality of display panels are fabricated on a substrate at the same time, and then cut to form a single independent display panel. Due to the difference in the stress of each film layer at different positions on the substrate, the expansion rate of the display panel at different positions on different substrates also has a large difference. [0003] Due to the large difference in the expansion rate of the display panel, when the display panel and the driver chip or the flexible circuit board are bonded according to the uniform process temperature, the bonding deviation will be abnormal, which will cause the bonding resistance to increase later and affect the performance. consumption. Contents of the invention [0004] Embodiments of ...
