Abstract

The invention discloses a display panel, a flexible circuit board and a display module. The display panel comprises a substrate and at least one row of input bonding pads arranged in a first direction, arranged in a binding region of the substrate; the first input bonding pads extend in a second direction; the second input bonding pads form second input bonding pad groups; the two second input bonding pad groups are located on the two sides of a first input bonding pad group respectively; each input bonding pad comprises a first end and a second end; an interval between any two adjacent inputbonding pads includes a first interval and a second interval; in each second input bonding pad group, the first interval and the second interval between the two adjacent second input bonding pads arenot equal; the first input bonding pad groups point to the second input bonding pad groups; and from the first input bonding pads and the second input bonding pads, which are adjacent, the first intervals are gradually increased in sequence, and the second intervals are gradually increased in sequence. The dislocation between the input bonding pads and output bonding pads in the binding process can be effectively reduced, thereby improving the binding yield.

Description

Technical field

[0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a flexible circuit board and a display module. Background technique

[0002] In the field of display technology, in order to realize the display of the display panel, the main driving chip is required to provide electrical signals to various circuit traces provided in the display panel. The prior art usually sets up a flexible circuit board to realize the main driving chip and the circuit in the display panel. The electrical connection of the trace. Generally, input pads are provided on the display panel, and output pads are provided on the flexible circuit board, and the input pads and the output pads are bonded and connected in a one-to-one correspondence through anisotropic conductive glue. In the bonding manufacturing process, due to the difference between the thermal expansion coefficient of the flexible circuit board and the substrate of the d...
