Example Embodiment
[0063] Example 1
[0064] A layer of ITO with a thickness of 40μm is deposited on the surface of the camera glass by meteorological deposition. Then, the ITO coating on the glass surface is etched into conductive lines by the screen etching method. The width of each conductive line is 10 μm, the pitch of each conductive line is maintained at 500 μm, and the error between the width of the conductive line and the pitch of the conductive line is less than 0.5%.
[0065] Both sides of the glass are plated with parallel positive and negative electrodes, and multiple conductive wires are alternately connected with the positive and negative electrodes. Connect the external DC power supply to the electrode, the voltage is 360V.
