Abstract

The invention relates to a data conversion method for a flexible light-emitting diode (LED) driver. The data conversion method comprises the following steps of: starting work; acquiring frame header data in line with a first protocol; acquiring frame data after the frame header data, and processing the frame data into parallel data; storing the parallel data; reading the parallel data after a certain time delay after the work is started, and converting the parallel data into serial data in line with a second protocol; and outputting the serial data. The invention also relates to a device for implementing the data conversion method of the flexible LED driver. The data conversion method and the data conversion device for the flexible LED driver have the advantages that a wiring distance is long, and a flexible LED is flexibly applied.

Description

technical field [0001] The invention relates to the fields of electronics and communication, and more specifically, to a data conversion method and device for a flexible LED driver. Background technique [0002] In recent years, with the rapid development of LED technology, there are more and more applications of LEDs, mainly in the two fields of lighting and display lighting. The core of lighting technology is to design and manufacture stable and durable constant current source chips, while display Brightening is to control the brightness by receiving data from MCU and using PWM (PulseWidthModulation, pulse width modulation). Among them, the display lighting technology is also developing in a diversified direction, including traditional LED outdoor screens and LED billboards, as well as the flexible LED display technology that has emerged in recent years. Flexible display technology is to assemble LED controllers and chips on FPC (flexible circuit board), which can be arra...
