Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mini LED and Micro LED display devices face challenges in repairing or replacing small-sized LEDs due to their small size, making brightness anomalies difficult to address.
Innovation Solution
A luminance compensation method that identifies the position of brightness-anomalous LEDs and adjusts the brightness of adjacent LEDs to compensate for the anomalous brightness without direct repair or replacement.

Engineering Contradiction Analysis
1Weight of moving object
If Mini LEDs or Micro LEDs are used to achieve lighter and thinner display devices, then the device weight and thickness are reduced, but the difficulty of repairing or replacing faulty LEDs increases significantly
Solution Approach 1:
The patent applies the self-service principle by enabling the light-emitting device to automatically detect and compensate for brightness anomalies without requiring manual repair. The system uses a detection unit to identify faulty LEDs and a compensation unit to adjust adjacent LEDs' brightness, allowing the device to self-diagnose and self-correct brightness issues, thereby eliminating the need for difficult manual repair of mini/micro LEDs
Solution Approach 2:
The patent uses adjacent light-emitting elements as intermediaries to compensate for faulty LEDs. Instead of directly repairing the defective mini/micro LED, the system adjusts the brightness of neighboring LEDs to mask or compensate for the anomaly, effectively using healthy elements as mediators to maintain overall display quality without requiring physical access to the tiny faulty components
2Manufacturing precision
If the size of light-emitting elements is reduced to achieve higher pixel density, then display resolution is improved, but the ease of repair and replacement deteriorates
Solution Approach 1:
The system automatically detects brightness anomalies in high-density mini/micro LED arrays and performs compensation without manual intervention. The detection unit identifies faulty elements and the compensation unit adjusts surrounding LEDs, enabling self-service repair that is particularly valuable for high-density displays where manual repair would be extremely difficult
Solution Approach 2:
The patent extracts the repair function from manual physical intervention and transfers it to an automated electronic compensation system. By separating the detection and compensation functions into dedicated units, the system eliminates the need for physical access to tiny high-density LEDs, effectively extracting the repair process from the mechanical domain to the electronic control domain

AI summary
A luminance compensation method of a light-emitting device is disclosed. The light-emitting device has a plurality of light-emitting elements. The luminance compensation method includes following steps of: obtaining a position of at least one of the light-emitting elements in a brightness anomalous status; and changing a brightness of at least one of the light-emitting elements disposed adjacent to the light-emitting element in the brightness anomalous status for compensating a brightness of the light-emitting elements in the brightness anomalous status.
