AI Technical Summary
Technical Problem
In transparent display devices, short circuits caused by unintended particles can turn subpixels into black spots, resulting in brightness degradation, which is particularly noticeable in transparent display devices.
Method used
The first electrode structure, which includes segmented electrodes and bridging electrodes, is connected to the driving transistor through multiple connection parts to ensure that even if some segmented electrodes experience unexpected particle short circuits, the other electrodes can still function normally.
Benefits of technology
Reduce or minimize black spot areas caused by unexpected particles to maintain the brightness and normal light emission function of the display device.
