Integrated Defect Compensation Circuit for Display Panels

The patent combines separate atypical defect compensation circuit and typical defect compensation circuit into a single integrated compensation circuit. The integrated circuit includes a first compensator for atypical defects, a second compensator for typical defects, and a multiplexer that selectively activates the appropriate compensator based on defect type detection, thereby reducing device complexity while maintaining compensation effectiveness for both defect types.

The integrated compensation circuit is designed to perform multiple functions: it can detect and compensate for both atypical display defects (caused by process variations) and typical display defects (caused by backlight unit issues) using a single circuit. The circuit includes defect type detection capability that automatically selects the appropriate compensation mode, making the circuit universal for handling different defect types without requiring separate dedicated circuits.

The patent merges the functionality of separate timing controllers for atypical and typical defect compensation into a single timing controller. The unified timing controller includes defect type detection logic that identifies whether the display defect is atypical or typical, and automatically configures the appropriate compensation parameters and activates the corresponding compensator, thereby reducing manufacturing cost and management complexity while maintaining compensation precision.

The timing controller is designed with dynamic configuration capability that adjusts its operation mode based on the detected defect type. When an atypical defect is detected, the controller configures the first compensator with appropriate parameters; when a typical defect is detected, it configures the second compensator accordingly. This dynamic adaptation allows a single timing controller to achieve the precision previously requiring separate dedicated controllers.
