1. The red in the picture is the HC245 chip, which plays the role of signal amplification. The chip 1 amplifies the signals of the half part of the unit board, that is, the first set of RGB data and the second set of RGB data. Chip 2 amplifies the signals of the lower half of the unit board, that is, the third group of RGB data and the fourth group of RGB data. Chip 3 amplifies ABCD row signals, CLK signals, SC latch signals, and OE control signals. Chip 4 amplifies all signals and sends them to the output interface of the unit board.
2. The blue in the picture is the driver chip of the LED light, which can be TB62726, MBI5024 and other chips. The main function is to control the column display on the LED unit board, TB62726 in the picture, the blue lights of the 1st and 4th columns are the control red lights, the blue lights of the 2nd and 5th columns are the control green lights, and the 3rd and 6th columns are the control blue lights. One TB62726 controls 16 columns, and one group has 3 TB62726, corresponding to red, green and blue LED Mesh Screen for Indoor Media Façade lights.
3. The green in the picture is the 4953 chip. The main function is to control the line display on the LED unit board, one 4953 controls 2 lines, and 8 controls 16 lines.
LED unit board signal direction analysis
1. CLK signal, SC latch signal, OE control signal direction: input—into red chip 3 at the same time, chip 4—into chip 2 at the same time, chip 1—into each TB62726 chip in parallel.
2. Signal direction of ABCD line: input—into the red chip 3 at the same time, chip 4—the output of chip 3 is connected to 4 green 4953 chips, and the output of chip 4 is connected to 4 green 4953 chips.
3. RGB data signal direction: Input—the first group of RGB data and the second group of RGB data enter chip 1, the third group of RGB data and the fourth group of RGB data enter chip 2—the R1 data of the first group of RGB data enters serially Blue chip 1, chip 4; G1 data enters blue chip 2, chip 5 serially. B1 data serially enters the blue chip 3, chip 6. The RGB data of other groups are deduced in turn.
