PLK 19 14A lamp beads are integrated with 19 14 driver chip and RGB chip in an 8-pin 5050 package to form a complete pixel.

The driving IC chip adopts serial standardized communication mode.

The driver IC has a built-in 5V regulator, and the voltage after series resistance can support DC6~24V. Under this working voltage, a common light source can be equipped.

The driving IC has a fixed constant current output of 18mA, and the brightness of 256 PWM levels can be adjusted.

Built-in power-on reset circuit, all registers are initialized to zero after power-on reset.

When the data transmission rate is 800Kbps and the refresh rate is 30 frames per second, the number of cascaded points can be no less than 1024 pixels.

TM 19 14D is a single-line and dual-channel transmission, which supports the breakpoint continuous transmission function, and the dual-channel digital interfaces (DIN and FDIN) of the chip are mutually cut.

In the input, the D0 pin forwards the cascaded data, so that the signal will not affect other normal work due to an abnormal drive, and the output is improved.

Product stability.

The driver IC has a built-in automatic signal shaping circuit to repair the data signal that may be distorted by the controller or the last chip.

Positive, adjust to the standard data waveform, and then forward to the next stage, so that the signal will not be distorted or attenuated as the cascade becomes farther away.
