1Measurement precision
If manual adjustment through OSD function is used for color calibration, then the display can be adjusted to correct color deviation, but the calibration process is time-consuming and imprecise
Solution Approach 1:
The display device performs automatic color calibration by itself using an integrated sensor and processor, eliminating the need for manual user adjustment. The sensor captures displayed images, the processor analyzes color deviations, and the system automatically adjusts display parameters to correct the deviations, making the calibration process self-service and eliminating time-consuming manual operations.

If automatic calibration function is used in conventional displays, then color calibration can be performed automatically, but the calibration is limited to color correction only and cannot synchronize with external data for enhanced calibration capability
Solution Approach 1:
The display device integrates multiple functions including display, sensing, processing, and communication capabilities into a single universal system. The sensor can detect various optical characteristics, the processor can perform different types of image analysis and calibration algorithms, and the device can communicate with external devices through multiple interfaces, making the system versatile and capable of performing both color calibration and advanced image control functions.
Solution Approach 2:
The system implements a feedback mechanism where the sensor continuously monitors the displayed image, the processor analyzes the captured image to detect color deviations and other display characteristics, and the system automatically adjusts display parameters based on this feedback. This closed-loop feedback system enables continuous optimization of display performance and allows synchronization with external calibration data sources for enhanced calibration capability.
