Abstract
Described are examples for controlling a dimming panel for a display device. A first indication of a measured amount of ambient light can be received. A second indication of a location at which an eye is gazing can be received. A power control signal can be transmitted to a section of the dimming panel that corresponds to the location to facilitate activating dimming in the section of the dimming panel.
Claims22
An apparatus for controlling a dimming panel for a display device, comprising:
- one or more processors configured to:
- receive a first indication of a measured amount of ambient light;
- receive a second indication of a location on the display device at which an eye is gazing;
- select, based on the location on the display device, a section from multiple sections of the dimming panel;
- and
- modify a light transmittance in the section of the dimming panel that corresponds to the location including applying a voltage to liquid crystal in the section to individually activate the liquid crystal in the section causing a dimming effect.
A method for controlling a dimming panel for a display device, comprising:
- receiving a first indication of a measured amount of ambient light;
- receiving a second indication of a location on the display device at which an eye is gazing;
- selecting, based on the location on the display device, a section from multiple sections of the dimming panel;
- and
- transmitting, to the section of the dimming panel that corresponds to the location, a power control signal to modify a light transmittance including applying a voltage to liquid crystal in the section to individually activate the liquid crystal in the section causing a dimming effect.
A non-transitory computer-readable device storing instructions thereon that, when executed by a computing device, cause the computing device to perform operations for controlling a dimming panel for a display device, comprising:
- receiving a first indication of a measured amount of ambient light;
- receiving a second indication of a location on the display device at which an eye is gazing;
- selecting, based on the location on the display device, a section from multiple sections of the dimming panel;
- and
- transmitting, to the section of the dimming panel that corresponds to the location, a power control signal to modify a light transmittance including applying a voltage to liquid crystal in the section to individually activate the liquid crystal in the section causing a dimming effect.
