Abstract
This publication describes techniques for off-angle color-shift compensation that accommodates a user’s viewing direction and use cases for devices including foldable OLED displays, particularly, foldable displays configured in an intermediate mode with a first display portion positioned in a first plane (e.g., as a display) and a second display portion positioned in a second plane at an angle to the first plane (e.g., as an input screen). The techniques include generating a Color Compensation lookup table (LUT) relating display input values with corresponding display output values (target color space), based on angle measurements between the first display portion and the second display portion. The Color Compensation LUT is stored on a computer-readable medium (CRM) of the device as device data. A Display Manager implemented on the CRM utilizes sensor data from sensors (e.g., radar sensors, gyroscope sensors, hinge sensors) to enable off-angle color-shift compensation that compensates for a color difference between the first display portion and the second display portion.
