Liquid crystal display lighting modes
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.
1. 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.
2. The device of claim 1 , wherein the different lighting mode comprises a wide gamut lighting mode that comprises the wide gamut LED light set turned on and the narrow gamut LED light set turned off.
3. The device of claim 1 , wherein the different lighting mode comprises a narrow gamut lighting mode that comprises the narrow gamut LED light set turned on and the wide gamut LED light set turned off.
4. The device of claim 1 , further comprising:
a light guide plate communicatively coupled to the LCD; and
the wide gamut LED light set and the narrow gamut LED light set communicatively coupled to a same side of the light guide plate.
5. The device of claim 1 , further comprising:
a light guide plate communicatively coupled to the LCD; and
the wide gamut LED light set and the narrow gamut LED light set communicatively coupled to different sides of the light guide plate.
6. The device of claim 1 , wherein the controller is a remotely managed controller.
7. 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.
8. The medium of claim 7 , further comprising instructions executable by the processor to place the LCD in high brightness lighting mode in response to a remote command.
9. The medium of claim 7 , further comprising instructions executable by the processor to adjust the LCD to the different lighting mode in response to a remote command.
10. 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.
11. The medium of claim 10 , further comprising instructions executable by the processor to:
adjust the LCD to a narrow gamut lighting mode by turning on the narrow gamut LED light set and turning off the wide gamut LED light set in response to the detected application reaching a narrow gamut lighting mode threshold; and
adjust the LCD to a wide gamut lighting mode by turning on the wide gamut LED light set and turning off the narrow gamut LED light set in response to the detected application reaching a wide gamut lighting mode threshold.
12. The medium of claim 11 , further comprising instructions executable by the processor to disable the high brightness lighting mode, the narrow gamut lighting mode, or the wide gamut lighting mode in response to a remote command.
13. The medium of claim 10 , wherein the instructions executable by the processor to adjust the LCD to the different lighting mode based on the detected application comprises are executable by the processor to adjust the LCD to the different lighting mode based on a preset lighting mode rule for the detected application.
