Narrow-bezel displays and touch screens: coverage of conductor tracks
Modern desktop monitors and large TV displays often do not feature a plastic frame - the so-called bezel. This not only looks elegant but enables multiple screens to be placed together to form a large display. The missing plastic frame does mean, however, that the highly reflective conductor tracks made of molybdenum, aluminum or copper on the TFT glass are not covered. This is where an additional MoOx anti-reflection layer comes in. Whereas metal molybdenum reflects around 60% of the incident light, an MoOx layer of the same thickness reflects less than 6% (at 550 nm). This provides excellent shielding for the conductor tracks.
