TruEbox 04MD is mainly used for signal driving of array light-emitting devices and supports up to 16*16 resolution array driving. It can provide 16 rows of select signals, 16 columns of feed signals, and 2 DC bias signals. TruEbox can customize the light-emitting of the array light-emitting device through the wireless Bluetooth module, the Android mobile terminal, and the self-designed APP that transmits the compiled array signal. With the matching thin film transistor (TFT) array chip, the TruEbox 04MD can realize the display and luminescence of new light-emitting devices such as QLED and perovskite LED.
