Abstract

The invention relates to the technical field of display, in particular to a display driving board, a preparation method thereof and a display device. The problems that in the prior art, due to the facts that the thickness of a first bonding pad is small, edge breakage occurs, and protection glue wraps the first bonding pad, resistance is too large when side face wiring makes contact with the firstbonding pad, and side face wiring pad printing is poor are solved. In the display driving board provided by the embodiment of the invention, the display driving board is provided with a display areaand a peripheral area, and the peripheral area comprises a binding area close to the first side of the display driving board; the display driving board comprises a substrate layer and a plurality of spaced first bonding pads which are arranged on the substrate layer and located in the binding area. One side face of each first bonding pad is flush with the first side face of the substrate layer, and the first side face of the substrate layer is the side face, corresponding to the first side of the display driving board, of the substrate layer. And the thickness of the first bonding pad is 0.5-2microns. The embodiment of the invention is used for increasing the contact area of the side wiring and the first bonding pad.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving board, a preparation method thereof, and a display device. Background technique [0002] The size of the light-emitting diodes used in the light-emitting diode display device is on the micron level, and it has the characteristics of independent control of the picture, independent light-emitting control, high brightness, low power consumption, ultra-high resolution and high color saturation. It will become one of the hot spots in the development of display technology in the future. Contents of the invention [0003] The main purpose of the present invention is to provide a display driving board, a manufacturing method thereof, and a display device. It is used to solve the problems of excessive resistance when the side traces are in contact with the first pad and poor printing of the side traces caused by factors such as thin thickness of the first pad, edge c...
