AI Technical Summary
Technical Problem
In light-emitting devices, inconsistent brightness in different light-emitting zones leads to problems such as uneven brightness and visual fragmentation, affecting appearance quality and information recognition effectiveness.
Method used
By setting a first electrode and a second electrode on the substrate, and dividing the substrate area into multiple light-emitting zones through electrode wires, and setting multiple LEDs in each zone, the equivalent impedance of the current loop is ensured to be consistent, thereby ensuring that the luminous brightness of each LED is consistent.
Benefits of technology
This effectively avoids uneven brightness caused by differences in power supply paths, improving the uniformity of light-emitting zones and overall display quality.
