What it is
A segment of a panel with 768 RGB LEDs on one side driven by chains shift registers on the other side.
The PCB is marked:
BTC004.1 24x32_10 RGB
Not sure which city is it operated in. Brno has green only panels and Bratislava got RGB but of different size.
Theory of operation
LEDs are organized into 24 x 32 pattern on one side, drivers are organized into a grid of 18 x 16 drivers. Three lines of LEDs snake around and are driven by a line of drivers on the other side.
Rows do have common CLK and LE signals. This means both halves of the row must be fed in parallel, but rows are entirely independent of each other.
