OLD light source drive control circuit and OLD lamp

摘要

The present invention provides an OLED light source driving control circuit and an OLED lamp. The driving control circuit includes a DC/DC constant voltage module, an external transceiver, a first internal transceiver, a microprocessing module, a linear constant current module and an OLED screen light source; the microprocessing module communicates with the first internal transceiver and feeds back the detected output voltage to the DC/DC constant voltage module to control the operation of the DC/DC constant voltage module; the first internal transceiver is connected with a linear constant current module through a differential bus; The linear constant current module includes a plurality of linear constant current chips, each of the linear constant current chips is provided with a second internal transceiver, wherein the differential bus interface of the second internal transceiver is a differential bus connected to the differential bus interface of the first internal transceiver, respectively connected to a communication line. The present invention has a stronger anti-interference ability, and effectively improves the overall circuit conversion efficiency of the drive system.
