Advanced LCD

     In pursuit of the greater possibilities of LCD technology
     In order to meet the more diversified demands for displays, Sharp is not stopping at improving visual quality,

     but is challenging the boundaries of integrating displays into advanced systems and giving them more

     advanced functions. We shall continue to pursue the possibilities of LCD technology by combining the

     technology that we have accumulated over the years.
