Abstract
Example implementations relate to liquid crystal display (LCD) lighting modes. An example device can include an LCD, a wide gamut light-emitting diode (LED) light set to backlight the LCD, a narrow gamut LED light set to backlight the LCD and a controller communicatively coupled to the LCD. The controller can switch the LCD between a wide gamut lighting mode, a narrow gamut lighting mode, and a high brightness lighting mode in response to changes in ambient light and content displayed on the LCD.
Claims13
A device, comprising:
- a liquid crystal display (LCD);
- a wide gamut light-emitting diode (LED) light set to backlight the LCD;
- a narrow gamut LED light set to backlight the LCD;
- and
- a controller communicatively coupled to the LCD to:
- in response to detecting an ambient light amount associated with the LCD being above a particular threshold and a white content separate and distinct from the ambient light displayed on the LCD being below a different particular threshold, turn on the wide gamut LED light set and the narrow gamut LED light set to place the LCD in a high brightness lighting mode,
- wherein the different particular threshold comprises a white content on the LCD of 20 percent;
- and
- in response to detecting the ambient light amount being below the particular threshold and the white content being above the different particular threshold, adjust the LCD to a different lighting mode.
A non-transitory machine-readable medium comprising instructions executable by a processor to:
- in response to detecting an ambient light amount associated with a liquid crystal display (LCD) being above a particular threshold and a white content separate and distinct from the ambient light displayed on the LCD is below a different particular threshold, turn on a wide gamut light emitting diode (LED) light set and a narrow gamut LED light set associated with the LCD to place the LCD in a high brightness lighting mode,
- wherein the different particular threshold comprises a white content on the LCD of 20 percent;
- and
- in response to detecting the ambient light amount being below the particular threshold and a white content separate and distinct from the ambient light displayed on the LCD is above the different particular threshold, adjust the LCD to a different lighting mode using the wide gamut LED light set and the narrow gamut LED light set and based on detected content displayed on the LCD.
A non-transitory machine-readable medium comprising instructions executable by a processor to:
- detect an ambient light amount associated with a liquid crystal display (LCD) using a sensor integrated with the LCD;
- detect a white content separate and distinct from the ambient light displayed on the LCD;
- in response to the ambient light amount being above a particular threshold and the white content below a different particular threshold, turn on a wide gamut light emitting diode (LED) light set and a narrow gamut LED light set associated with the LCD to place the LCD in a high brightness lighting mode,
- wherein the different particular threshold comprises a white content on the LCD of 20 percent;
- and
- in response to the ambient light amount being below the particular threshold, the white content below the different particular threshold, and based on a detected application running on a computing device communicatively coupled to the LCD, adjust the LCD to a different lighting mode using the wide gamut LED light set and the narrow gamut LED light set.
