ITO conductive glass is based on the glass of sodium, calcium boron or silicon substrate, and based on the use of magnetron sputtering coated with a layer of indium tin oxide (commonly known as ITO) film into manufacture. Resolutions ITO conductive glass, but also in the ITO layer prior to plating, plated with a layer of silicon dioxide barrier layer to prevent the glass substrate to the box on the LCD in the sodium ion diffusion. Dedicated high-end LCD monitors in the sputtering of ITO glass substrate before ITO layer of glass should be polished to get a more uniform display control. ITO glass substrate liquid crystal display is generally within the exclusive super float glass, Zinc oxide coating all surfaces tin side of float glass. Therefore, the LCD will eventually float along the direction of the law of the case of a wave is not flat.
In sputtering ITO layer, between the different targets and glass at different temperatures and movement mode, the resulting ITO layer have different characteristics. A number of manufacturers of glass ITO layer surface finish is often lower, more prone to "pitting" phenomenon; some manufacturers of glass ITO layer will appear with a high erosion interval, ITO layer etching, the more likely the lack of planning radiation-linear or with high resistance; other manufacturers of glass ceramic ITO layer appears groove joints.
The main components of ITO film is indium tin oxide. Only a few thousand angstroms in thickness of the case, through the high indium oxide, tin oxide conductive ability, LCD ITO glass is used in a high-transmittance of the conductive glass. Because ITO is highly absorbent, it will absorb moisture and carbon dioxide in the air and produce a chemical reaction and deterioration, Titanium dioxide commonly called "mildew" and therefore moisture when in storage. ITO layer in the active-price solution is easy to produce ion-ion replacement reaction, the formation of other conductive material and transmission of poor response, so in the process, try to avoid prolonged monovalent ions on the activity is the solution. ITO layer formed by a number of small grains, grain fission in the heating process will become smaller, thereby adding more grain boundaries, grain boundary electronic break when a certain loss of energy, so the ITO conductive glass ITO layer at 600 degrees The following will be as the temperature increases, resistance also increases.
ITO conductive glass by the resistor divider, divided into high-resistance glass (150 to 500 ohm resistor), Barium titanate ordinary glass (60 to 150 ohm resistor), low-resistance glass (resistance less than 60 ohms). High resistance glass is generally used for static protection, making use of the touch screen; ordinary glass is generally used in TN type liquid crystal displays and electronic interference; low resistance glass is generally transparent for STN LCD and circuit board. ITO conductive glass divided by size, there are 14 "x14", 14 "x16", 20 "x24" and other specifications; divided by thickness, with 2.0mm, 1.1mm, 0.7mm, 0.55mm, 0.4mm, 0.3mm and so on specifications, thickness of 0.5mm for the following main STN LCD display products.
