Abstract
An anti-reflection with high conductivity and transmission controlled multi-layer coating for Flat CRT products is provided which includes five layers coating by vacuum sputtering and one layer coating by conventional wet process. The first layer is formed by an oxide material. The second layer is arranged on an underlying first layer and is formed by a metal. The third layer is arranged on an underlying second layer and is coated by vacuum sputtering. The third layer provides high conductivity thin film with resistance as low as 10.sup.2 .OMEGA./square. The fourth layer is arranged on an underlying third layer and is formed by an oxide material. The fifth layer is formed by an oxide material. The fourth layer and fifth layer are coated by vacuum sputtering. The sixth layer is deposited on the top surface and is formed by a wet silica coating process.
