Abstract

Device, system, and method for display calibration. For example, an apparatus includes: one or more color sensors, embedded within a body of a mobile device, to measure one or more color attributes of a visual element displayed by a display unit of the mobile device when a lid of the mobile device is in a closed position; and a color calibrator to calibrate one or more parameters of the display unit based on the one or more color attributes measured by the one or more color sensors.

Claims

1. An apparatus comprising:

one or more color sensors, embedded within a body of a mobile device, to measure one or more color attributes of a visual element displayed by a display unit of the mobile device when a lid of the mobile device is in a closed position; and

a color calibrator to calibrate one or more parameters of the display unit based on the one or more color attributes measured by the one or more color sensors.

2. The apparatus of claim 1, comprising:

one or more ambient light sensors, embedded within the body of the mobile device, to measure light from a surrounding of the mobile device,

wherein the color calibrator is to calibrate one or more parameters of the display unit based on the light measured by the one or more ambient light sensors.

3. The apparatus of claim 1, comprising:

one or more Light Emitting Diode (LED) backlight sensors, embedded within the body of the mobile device, to measure LED backlight relative to the mobile device,

wherein the color calibrator is to calibrate one or more parameters of the display unit based on the LED backlight measured by the one or more LED backlight sensors.

4. The apparatus of claim 1, comprising:

one or more Cold-Cathode-Fluorescent-Lamp light sensors, embedded within the body of the mobile device, to measure Cold-Cathode-Fluorescent-Lamp light of the mobile device,

wherein the color calibrator is to calibrate one or more parameters of the display unit based on the Cold-Cathode-Fluorescent-Lamp light measured by the one or more Cold-Cathode-Fluorescent-Lamp sensors.

5. The apparatus of claim 1, comprising:

one or more temperature sensors, embedded within the body of the mobile device, to measure temperature from a surrounding of the mobile device,

wherein the color calibrator is to calibrate one or more parameters of the display unit based on the temperature measured by the one or more temperature sensors.

6. The apparatus of claim 1, comprising:

an overriding mechanism to override a pre-programmed function associated with closure of the lid of a mobile device and to maintain the display unit of the mobile device operational upon closure of the lid.

7. The apparatus of claim 6, wherein the display unit is to present a visual element upon closure of the lid of the mobile device, and wherein the visual element is to face the one or more color sensors.

8. The apparatus of claim 2, comprising:

a recalibration mechanism to initiate recalibration of the display unit of the mobile device based on a change in ambient light measured by the one or more ambient light sensors.

9. The apparatus of claim 1, comprising:

a calibration button, embedded within the body of the mobile device, to initiate a calibration process.

10. A method comprising:

presenting a visual element on at least a portion of a display unit of a laptop computer while a lid of the laptop computer is in a closed position;

measuring a color attribute of the visual element while the lid of the laptop computer is in a closed position; and

calibrating one or more parameters of the display unit based on the measured color attribute.

11. The method of claim 10, comprising:

measuring a parameter selected from the group consisting of;

an ambient light parameter, a Cold-Cathode-Fluorescent-Lamp light parameter, a Light Emitting Diode (LED) backlight parameter, and a temperature parameter,

wherein calibrating the one or more parameters of the display unit takes into account the measured parameter.

12. The method of claim 10, comprising:

detecting that a calibration button, embedded within a body of the laptop computer, is pressed; and

detecting that the lid of the laptop computer is in closed position.

13. The method of claim 10, comprising:

generating a notification to a user to close the lid of the laptop computer upon initiation of a calibration process.

14. The method of claim 13, comprising:

generating a subsequent notification to the user to open the lid of the laptop computer upon completion of the calibration process.

15. The method of claim 11, comprising:

periodically re-measuring the parameter; and

initiating a recalibration process based on the re-measured parameter.
