[0003] There are two existing processes: 1. Printing semi-transparent black ink, which should be in the same color system as the frame color and close to it; too dark or too light will easily cause color difference and other problems; 2. The glass is vacuum-coated with an anti-reflection film to increase the light transmittance of the glass. When the glass cover is assembled with the display, the visual effect is slightly worse and the integrated effect is weak. Summary of the invention
