Abstract: Example implementations relate to a light absorption privacy film. For example, a privacy film may include privacy gates that at least partially block content displayed by a display panel when the privacy film is adjacent to the display panel. The privacy film may also include light absorption material to absorb light from the content.

Abstract: An electrophoretic privacy device may include an electrophoretic cell coupled between a first electrode and a second electrode. The electrophoretic cell may comprise a plurality of semi-transparent positively-charged particles and a plurality of semi-transparent negatively-charged particles. The particles may be dispersed in a dielectric fluid in the electrophoretic cell. At least one of the first electrode and the second electrode may be transparent.

Abstract: Example implementations relate to a touch screen light absorption layer. For example, a display device may include a touch screen sensor to receive a touch input, a display panel to display content based on the touch input, and a light absorption layer adjacent to the touch screen sensor. The light absorption layer may absorb blue light.
