SODALIME GLASS SUBSTRATE FOR SURFACE LIGHT SOURCE DEVICE, METHOD OF FORMING THE GLASS SUBSTRATE, SURFACE LIGHT SOURCE DEVICE HAVING THE GLASS SUBSTRATE AND BACK LIGHT UNIT HAVING THE SURFACE LIGHT SOURCE DEVICE

摘要

sodium ions and potassium ions in the glass surface ion-exchanged soda- lime glass surface light source device including a substrate includes a first substrate , the second substrate is spaced apart arrangement on top of the first substrate to form an inner space , and a voltage is applied to apply a voltage to the internal space . The first substrate and the second substrate is made of at least one substrate of soda lime glass by ion exchange with sodium ions and potassium ions in the glass surface . The surface light source device is the removal of sodium ions may increase the strength of the can solve the problem of discoloration due to sodium ion addition glass substrate itself .
