AI Technical Summary

Technical Problem

When existing LED displays use AM driving, the components occupy a large area, are costly, and suffer from severe signal transmission loss, requiring a large number of signal enhancement chips.

Method used

It adopts a hub board and lamp board structure. Each lamp board is equipped with a timing controller and multiple lamp driver integrated units. The hub board transmits HDMI data to the lamp board's connector interface through the connector interface. The timing controller processes the data, and the drive data and timing data are directly transmitted to the lamp driver integrated unit through the wiring on the lamp board, reducing the use of connectors and enhancement chips.

Benefits of technology

It saves costs, reduces the use of components, simplifies circuit board wiring, and improves the stability and signal transmission efficiency of AM-driven display units.
