Abstract
A display for an information handling system includes a thin-film transistor (TFT) glass and a color filter layer. A black matrix layer is in physical communication with the TFT glass and with the color filter layer. The black matrix layer is disposed between the TFT glass and the color filter layer, and absorbs light that moves through the TFT glass.
Claims18
A display for an information handling system, the display comprising:
- a thin-film transistor (TFT) glass;
- a color filter layer;
- a black matrix layer in physical communication with the TFT glass and with a first surface of the color filter layer, wherein the black matrix layer is disposed between the TFT glass and the color filter layer, and the black matrix layer absorbs light that moves through the TFT glass, wherein a first amount of light reflected through the TFT glass is less than a second amount of light received at the TFT glass;
- and
- a copper metal layer in physical communication with a second surface of the color filter layer that is opposite the black matrix layer, wherein the color filter is disposed between the black matrix layer and the copper metal layer.
