Basic structure of LED light column display
Basic structure of LED light column display
In this structure, high brightness light emitting diode chips are arranged in a straight line, and 100 chips are divided into 10 groups, each group has 10 chips. Each group shares a common cathode, and every anode with the same medium sequence is attached to the anode roads Y1,Y2,...,Y10, 10 cathodes are respectively X1,X2,...,X10, then they constitute a 10x10 matrix. This device works with matrix-scanning mode, so it is called matrix-scanning beam display device. This device also set a chip under zero line of in device settings for indicator.
