TOPOLOGY OF DISTRIBUTING AND CONNECTING LEDS IN A LARGE AREA MATRIX
摘要
A LED circuit comprises an array of LEDs is arranged in a matrix. The matrix is connected to at least three power rail lines. The LEDs are formed as a first LED arrangement (34) between a first power rail line (30) and a second power rail line (32) and a second LED arrangement (36) between the second power rail line (32) and a third power rail line (30) of the same voltage as the first power rail line. This means there are alternating power rail lines interspersed with the matrix of LEDs. This enables the driving voltages to be kept low and it improves scalability of the design.
