AI Technical Summary
The organic light emitting display device may cause dark spot problems due to short-circuit defects between the anode electrode and the cathode electrode, and it is difficult for existing repair processes to accurately detect and repair semidark defects, which affects the productivity and environmental impact.
The divided subpixels are independently driven by dual transistors with mirror structures. By automatically detecting the semi-dark repair targets, the beat time of the repair process is reduced and the reliability of the manufacturing process is improved.
By automatically detecting the semi-dark repair targets, the time of the repair process is reduced, the yield of production is improved, the generation of greenhouse gases is reduced, and environmental and social management benefits are improved.
