Indium tin oxide coated glass (ITO coated glass) is just one type of TCO conductive glass types. Our ITO coated glass is manufactured using an ultra-thin float glass as the substrate after glass has undergone cutting, edging, polishing, and washing processes. We use a magnetron sputtering technique to deposit silicon dioxide and indium tin oxide onto the ITO coated glass in a vacuum, high temperature environment.
ITO coated glass features a simultaneous low resistance and high transmission making it ideal for use in LCD panels (TN, STN and HTN) and touch screen panels.
The ITO coated glass for LCDs will be coated a silica barrier layer to effectively inhibit sodium ion diffusion and increase both quality and durability of ITO coated glass slides. The glass will be polished before ITO coating to obtain a more even display control.
The thin transparent conductive coating on ITO coated glass is made of indium tin oxide.
The resistivity of an ITO sheet ranges between 2Ω to 500Ω.
The thickness of ITO film is 150Å to 2050 Å. The thickness of the ITO sheet is 0.4MM to 5MM.
Its transmission is more than 80% at 550nm light-wave.
ITO coated glass features a uniform coating thickness, high density, stable physical and chemical properties, uniform resistivity across the surface, uniform transmission, and high VIS-NIR transmittance.
This product is widely used in LCD panels (TN, STN, HTN), ePaper panels, COG displays, COB displays, touch screen panels, and other screen types.

Other thicknesses and dimension can be customized according to your requirements.
The conductivity of indium tin oxide is inversely proportional to its surface resistance.
ITO coated glass can be cut into various shapes including square, rectangle, round, and other shapes to meet your requirements.
Glass thickness for coating: 0.4mm to 5mm
Glass Size: 14”×16”, 370×470mm, 400×500mm, 450×550mm, 500×600mm. Other sizes also can be customized.
The accuracy error is ±1mm for the dimension of the glass, verticality is controlled in 90°±1°, the resistance uniformity can be controlled in the range of 8%, and the sheet resistance can be adjusted from 5Ω to 500Ω.

Physical and chemical stability
Resistance to alkali
After soaking for 5 minutes at a temperature of 60±2℃ and a concentration of 10% in NaOH (Analytical reagent) solution, the sheet resistance value of the ITO conductive coating should not be greater than that of the original value of 110%.
After immersing 2min in the 6% hydrochloric acid (Analytical reagent) solution at a temperature of 25±2℃, the sheet resistance value of the ITO conductive coating should not be greater than that of the original value of 110%.
After the immersion of 5min in acetone (Analytical reagent) or anhydrous ethanol (Analytical reagent) at a temperature of 25±2℃, the sheet resistance value of ITO conductive coating should not be greater than original resistance value of 110%.
Take a 100mm long tape to adhere tightly to the surface of the film, ensure there is no air in the paste surface, and 10s later, tear down the tape with the strength vertically and steadily, the film should not be damaged.
After rubbing 1000 times on the friction test machine, the sheet resistance of the ITO electric film should not be greater than the original resistance value of 110%.
The wooden box has a sign attached that records requirement information, including the product name, quality level, membrane structure, nominal resistance, glass substrate size, quantity, weight, production date, manufacturing, moisture resistance levels, and a fragile or up sign.
The ITO coated glass is separated by compartment paper or plastic compartments to effectively prevent damage to the glass and coating caused by sliding and friction.
The ITO coated glass uses vacuum packaging or kraft packaging. A small pack contains 20 pieces of ITO coated glass which are wrapped in a plastic bag for dampness resistance. Each wooden box features 2 to 4 bags of desiccant to keep the interior dry.
ITO coated glass should be stored with its package in a dry, dark and clean place with no exposure to corrosive materials or gas, and a humidity of no more than 50%. So long as the package stays intact, ITO coated glass should be stored for no more than 6 months before use.
