AI Technical Summary
Technical Problem
In existing LED display panels, a large number of constant current driver chips result in a large area and high cost, and the long signal traces lead to high electromagnetic coupling.
Method used
By incorporating resistors and signal generation circuits into the driver chip, the number of external pins is reduced, the number of output pins is increased, and the arrangement of LEDs and signal traces are optimized.
Benefits of technology
This reduces the footprint and cost of the driver chip on the circuit board, reduces signal traces, and reduces electromagnetic coupling.
