Abstract

A dual display housing information handling system and method comprising a first display screen side having a first portion or first display panel of a display screen, a second display screen side, hinged to the first display screen side, having a second portion or a second display panel of the display screen, and a second display screen side RGB detector to activate and the first display to test flash and a first display screen side RGB detector to activate and the second display to test flash and. A controller to determine operating color temperature shift for comparison to detect burn-in differences from color temperature readings by the first display screen side RGB detector and the second display screen side RGB detector, and if the difference between operating color temperatures measured between the first portion of the display screen and second portion of the display screen reaches a threshold difference, the controller implementing display color shift management to provide adjusted color mapping data to adjust at least one color component of the first or second display screen side to balance the operating color temperatures between the first portion of the display screen and second portion of the display screen.

First claim

What is claimed is:

1. A dual display housing information handling system comprising:
a first display screen side having a first portion of a display screen;
a second display screen side, hinged to the first display screen side, having a second portion of the display screen;
a second display screen side RGB detector to activate and the first display to test flash;
a first display screen side RGB detector to activate and the second display to test flash;
a controller to determine operating color temperature shift to detect burn-in differences from comparison of color temperature readings from the first display screen side RGB detector and the second display screen side RGB detector; and
if the difference between operating color temperatures measured between the first portion of the display screen and second portion of the display screen reaches a threshold difference, the controller implementing display color shift management to provide adjusted color mapping data to adjust at least one color component of the first or second display screen side to balance the operating color temperatures between the first portion of the display screen and second portion of the display screen.

2. The dual display housing information handling system of claim 1 , wherein the first portion of the display screen is a first display panel mounted in the first display screen side and a second portion of the display screen is a second display panel mounted in the second display screen side of the dual display housing information handling system.

3. The dual display housing information handling system of claim 1 , further comprising:
the first display screen side RGB detector is a first M×N RGB detector matrix for detecting color brightness levels for a corresponding OLED cell matrix from the second display screen side;
the second display screen side RGB detector is a second M×N RGB detector matrix for detecting color brightness levels for a corresponding OLED cell matrix from the first display screen side.

4. The dual display housing information handling system of claim 1 , further comprising:
a configuration sensor hub to detect closing configuration of the first display screen side to within a closing configuration threshold angle of the second display screen side and, if so, implementing color shift management.

5. The dual display housing information handling system of claim 1 , further comprising:
the controller to compare a cumulative operating time of the first display screen side and a cumulative operating time of the second display screen side with an expected color shift model for display portions of the type used for the first display screen side and the second display screen side; and
determine if threshold cumulative operating time of either the first or second display screen side has passed before activating the first display screen side RGB detector and second display screen side RGB detector.

6. The dual display housing information handling system of claim 1 , further comprising:
the controller to determine a usage configuration of the first display screen side relative to the second display screen side of the dual display housing information handling system; and
the controller implementing display color shift management to provide adjusted color mapping data if the usage configuration detected includes the first display screen side viewable simultaneously with the second display screen side by a user.

7. The dual display housing information handling system of claim 1 , further comprising:
an ambient light detector to detect the ambient lighting condition level around the dual display housing information handling system; and
the controller implementing display color shift management to provide adjusted color mapping data when the ambient lighting condition level does not exceed a light level threshold to overwhelm operation of the first display portion or the second display portion of the display screen when viewed by a user.

8. A dual display housing information handling system comprising:
a first display screen side having a first portion of a display screen;
a second display screen side, hinged to the first display screen side, having a second portion of the display screen;
the first display screen side including a first M×N RGB detector matrix for detecting color brightness levels for a corresponding OLED cell matrix in the second display screen side from a test flash of the second display screen side;
the second display screen side including a second M×N RGB detector matrix for detecting color brightness levels for a corresponding OLED cell matrix in the first display screen side from a test flash of the first display screen side;
a controller implementing display color shift management to determine differences in color brightness readings between a first OLED cell matrix location of the first portion of the display screen and a second OLED cell matrix location of the second portion of the display screen to compare operating color brightness degradation shifts to detect burn-in differences; and
if a threshold operating color brightness shift difference level is measured between the first OLED cell matrix location and the second OLED cell matrix location, the controller to provide adjusted color mapping data to adjust at least one color component at the first or second OLED cell matrix location to balance the operating color brightness levels between the first and second OLED cell matrix locations.

9. The dual display housing information handling system of claim 8 , wherein the first portion of the display screen is a first display panel mounted in the first display screen side and a second portion of the display screen is a second display panel mounted in the second display screen side of the dual display housing information handling system.

10. The dual display housing information handling system of claim 8 , wherein the threshold operating color brightness shift difference is greater than a 3% difference in any measured color component between the first OLED cell matrix location and the second OLED cell matrix location.

11. The dual display housing information handling system of claim 8 , wherein adjustment of at least one color component at the first or second OLED cell matrix location includes increasing brightness of that color component.

12. The dual display housing information handling system of claim 8 , further comprising:
the controller to determine a usage configuration of the first display screen side relative to the second display screen side of the dual display housing information handling system; and
the controller implementing display color shift management to provide adjusted color mapping data if the usage configuration detected includes the first display screen side viewable simultaneously with the second display screen side by a user.

13. The dual display housing information handling system of claim 8 , further comprising:
the controller to determine a graphics intensity categorization of an application program operating on the first display screen side or the second display screen side of the dual display housing information handling system; and
the controller implementing display color shift management to provide adjusted color mapping data if the graphics intensity categorization requires optimal color matching on both the first and second display screen sides.

14. A dual display housing information handling system comprising:
a first display screen side having a first portion of a display screen;
a second display screen side, hinged to the first display screen side, having a second portion o
