ABSTRACT

In order to quickly and clearly recognize characters or images through display glass, glare of the glass must besuppressed. In this study, we tried to reduce glare by analyzing changes in glass surface shape and optical propertiesthrough etching process. The etching process was performed as a function of concentrations of the etching solutions, BOEand HF. During the etching process, a compound containing F ion was generated on the surface of the glass, forming anirregular pattern in the form of a projection, and thus various optical properties of the glass were changed; reflectance of2.5~4.6 %, haze of 4.5~6.6 %, transmittance of 77~92 %, and gloss of 82~107 GU. As a result, optimum etching conditionwas obtained to minimize the loss of other optical properties while suppressing glare of the glass.
