Abstract

The invention relates to the field of display technology, in particular to a display driving board, a preparation 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 chipping, and protective glue wrapping in the related art. An embodiment of the present invention provides a display driving board, the display driving board has a display area and a peripheral area, the peripheral area includes a binding area close to the first side of the display driving board; the display driving board includes a base layer , and disposed on the base layer and located at a plurality of spaced first pads in the bonding region; one side of each of the first pads is flush with the first side of the base layer , the first side of the base layer is the side of the base layer corresponding to the first side of the display driving board; the thickness of the first welding pad is 0.5-2 microns. The embodiment of the present invention is used to increase the contact area between the side wiring and the first 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.
