Abstract

An active array device comprises a base plate, a plurality of scanning lines, a plurality of data wires, a plurality of pixel units, a static discharge ring, a circuit board and a static protective circuit, wherein the scanning lines, the data wires, the pixel units and the static discharge ring are arranged on the base plate and the data wires are vertically and horizontally crossed on the scanning lines. The static protective circuit is coupled between the static discharge ring and the circuit board and is used to prevent static electricity from entering into the base plate through the circuit board.

Description

technical field [0001] The present invention relates to an active array device, in particular to an active array device with electrostatic protection function. Background technique [0002] Generally speaking, the electrostatic voltage existing in the environment may be as high as thousands of volts, and this electrostatic voltage as high as thousands of volts will generate a huge electrostatic current. If this huge electrostatic current flows into the circuit, for example, into a In the active array device, it will cause damage to the electronic components in the active array device. In order to prevent the active array device from being damaged by electrostatic current, an electrostatic protection circuit is usually provided in the active array device. The electrostatic protection circuit provides an electrostatic discharge path to prevent electrostatic current from flowing into the active array device and damaging the electronic components of the active array device.
