Description

technical field

[0001] The invention relates to the display field, in particular to a driving circuit board and a display device. Background technique

[0002] An installation circuit is arranged on the non-display area of ​​the substrate of the screen body of the display device. The mounting circuit usually includes input pads and output pads disposed opposite to each other, with an exposed test circuit between the input pads and the output pads. The input pins and output pins of the integrated circuit chip are respectively connected to the input pads and the output pads, so that the integrated circuit chip is electrically connected to the substrate.

[0003] In the prior art, the test circuit is easily damaged, especially easily broken down by static electricity. After the test circuit is damaged, it will lead to wrongly judge whether the screen body is good or not. This is very unfavorable for the production of the screen body. Contents of the invention
