AI Technical Summary
Technical Problem
Existing LED display devices suffer from reduced reliability and high power consumption due to defective pixels during the transfer of micro LED devices to thin-film transistor array substrates.
Method used
The pixel design includes a first light-emitting part, a second light-emitting part, a common connection pattern, and a third light-emitting part. Defective pixels are repaired through redundant circuits and a common connection pattern, and power consumption is reduced through series connection.
Benefits of technology
This improves the reliability and yield of LED display devices while reducing power consumption.
