A kind of universal circuit board of shorting bar

Abstract

A universal circuit board (100) of a short-circuiting bar. The universal circuit board (100) comprises a circuit board substrate (1), and signal inputting interfaces (2) and signal outputting interfaces (3) all borne on the circuit board substrate (1). The signal inputting interfaces (2) are of at least two types and are used for inputting different signals. Different output signals are output through the signal outputting interfaces (3). Inputting pins (20) of the signal inputting interfaces (2) are in one-to-one butt joint with outputting channels (30) of the signal outputting interfaces (3). By setting a specific wiring mode between the inputting pins (20) of different signal inputting interfaces (2) and the outputting channels (30) of the signal outputting interfaces (3), different signal inputting interfaces (2) can be connected to a same circuit board (100), thereby implementing signal switching of different types of products.

Description

technical field [0001] The invention relates to a circuit board, in particular to a circuit board design suitable for shorting bars. Background technique [0002] Shorting bars are generally used to prevent electrostatic breakdown of lines and for glass panel segment testing of RBG and other pictures. In the existing shorting bar circuit board, the signal input of the shorting bar panel (Shorting bar PAD) of each size is different, and the existing circuit board has only one input and output mode, and only one signal input can be connected. For the interface, each input signal is the same, and the output signal is also the same, which leads to the need to constantly adjust the output signal contacts when the product is switched. The prolonged time of changing the line will waste production capacity, and it is easy for the operator to make mistakes in wiring, resulting in abnormal panel screen. If you need to plug in different signal input interfaces, you need to change the ...

Problems solved by technology

In the existing shorting bar (Shorting bar) circuit board, the signal input of the shorting bar panel (Shorting barPAD) of each size is different, and the existing circuit board has only one input and output mode, and can only access one signal input The interface, each input signal is the same, and the output signal is also the same, resulting in the need to constantly adjust the output signal contacts when the product is switched. The time for changing the line is prolonged, which will waste production capacity, and it is easy for the operator to make a wrong connection, resulting in an abnormal panel screen.

If you need to plug in different signal input interfaces, you need to change the internal wiring of the circuit board to change the output of the signal to adapt to the change of the input signal. The wiring operation is cumbersome, and it is easy to cause wiring errors. The practicability is not strong.
