<p>The present invention relates to a transparent electrode structure for a touchscreen applied to transport equipment, which is obtained by sequentially stacking, on a substrate, Y2O3 with a thickness of 60 to 80Å, TiO2 with a thickness of 45 to 65Å, SiO2 with a thickness of 553 to 573Å, TiO2 with a thickness of 127 to 147Å, SiO2 with a thickness of 279 to 299Å, and Indium Tin Oxide (ITO) with a thickness of 240 to 260Årespectively by electron beam deposition. The transparent electrode structure for a touchscreen applied to transport equipment can form transmissivity of a transparent electrode to be closest to its own transmissivity of glass or a polymer film that is a basic member of panel manufacture, thereby improving transparency such that a pattern of the transparent electrode cannot be identified with the naked eye after forming the pattern. Furthermore, an extinction coefficient of ITO with a short wavelength band (450nm) can be controlled to suppress yellowing of the ITO, thereby solving deterioration of transmissivity of a display light source and color variation problems thereof after assembly with the light source, and Y2O3 is used as a stacking material of the structure to improve fire resistance and chemical resistance, thereby being advantageous to cope with a change in an external environment. That is, the transparent electrode structure for a touchscreen applied to transport equipment can improve visibility, fire resistance, and chemical resistance of a final panel product.</p> |
