3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 Anti-glare and anti-reflective glass for electronic display
The glass surface is modified by chemical etching method, then the glass has the
functions of reducing the glare and reflection, and increasing the visible light
transmission; which is suitable for the display field.
3.2 Point Defect
The defects on the glass surface like pits, different color points, particles, etc. after the
chemical etching.
