Abstract

An information handling system having a first housing, a second housing interoperably coupled to the first housing and movable relative to the first housing between an open configuration and a closed configuration, and a sensor integrated with a housing of the first housing and the second housing. A display integrated with the same housing of the first housing and the second housing as the sensor and a light guide integrated with a different housing of the first housing and the second housing from the sensor, the light guide having an input and an output. In the closed configuration, the input faces a portion of the display and channels light having display attributes from the display to the output and the sensor is at least partially aligned with the output and receives at least some of the channeled light.

Claims

1. An information handling system comprising:

a display housing comprising a display and a sensor;

an input housing comprising an input device, a light guide and processing circuitry, interoperably coupled to the display housing and movable relative to the display housing between an open configuration and a closed configuration;

wherein the light guide comprises a plurality of light guide inputs and a light guide output;

wherein the processing circuitry is configured to process information received via the light guide, the processing circuitry comprising a display-calibration activator;

wherein the light guide is arranged in the input housing such that the plurality of light guide inputs face multiple regions of the display when the display housing and the input housing are in the closed configuration and channel light having display attributes from the multiple regions of the display to the light guide output; and

wherein when the display housing and the input housing are in the closed configuration the light guide output extends over and at least partially aligns with the sensor thereby allowing the sensor to receive at least some of the channeled light.

2. The information handling system of claim 1, wherein the sensor forwards adjustment data to the processing circuitry to initiate display calibration.

3. The information handling system of claim 1, wherein the light guide is made of a material having good transmittance in a visible light region.

4. The information handling system of claim 1, wherein the display is a touch-screen display.

5. The information handling system of claim 1, wherein the sensor comprises an ambient light and color sensor.

6. The information handling system of claim 1, wherein the display attributes comprise at least one of a color level, a contrast level, a saturation level, a hue level, and a brightness level of the display.

7. The information handling system of claim 1, wherein the display housing comprises a lid of the information handling system.

8. The information handling system of claim 1, wherein the processing circuitry comprises a calibration module that performs calibration of the display.

9. A method of calibrating a display of an information handling system, the method comprising:

coupling a display housing with an input housing, wherein the display housing and the input housing are movable between an open configuration and a closed configuration;

integrating a sensor and a display with the display housing;

integrating an input device and processing circuitry with the input housing;

processing, via the processing circuitry, information received via a light guide, the light guide comprising a plurality of light guide inputs and a light guide output;

wherein the light guide is arranged in the input housing such that the plurality of light guide inputs face multiple regions of the display when the display housing and the input housing are in the closed configuration and channel light having display attributes from the multiple regions of the display to the light guide output; and

wherein when the display housing and the input housing are in the closed configuration the light guide output extends over and at least partially aligns with the sensor thereby allowing the sensor to receive at least some of the channeled light.

10. The method of claim 9, further comprising forwarding, by the sensor to the processing circuitry, adjustment data to initiate display calibration.

11. The method of claim 10, wherein the processing circuitry is configured to process information received via the light guide.

12. The method of claim 10, wherein the processing circuitry comprises a calibration module that performs calibration of the display.

13. The method of claim 9, wherein the light guide is made of a material having good transmittance in a visible light region.

14. The method of claim 9, wherein the display is a touch-screen display.

15. The method of claim 9, wherein the sensor comprises an ambient light and color sensor.

16. The method of claim 9, wherein the display attributes comprise at least one of a color level, a contrast level, a saturation level, a hue level, and a brightness level of the display.

17. The method of claim 9, wherein the display housing comprises a lid of the information handling system.

18. A display-calibration method comprising:

disposing a display integrated with a display housing;

positioning a light guide comprising a plurality of light guide inputs within an input housing comprising an input device and processing circuitry, wherein the input housing is interoperably coupled to the display housing and movable relative to the display housing between an open configuration and a closed configuration of an information handling system;

wherein the light guide is arranged in the input housing;

at least partially extending over and aligning with a light guide output of the light guide by a sensor integrated with the display housing;

the plurality of light guide inputs receiving light having display attributes from multiple regions of the display when the display housing and the input housing are in the closed configuration;

the light guide channeling at least some of the received light to the light guide output;

the sensor receiving at least some of the channeled light from the light guide output when the display housing and the input housing are in the closed configuration; and

forwarding, by the sensor to the processing circuitry, data for use in calibration of the display.
