Problems solved by technology
In order to ensure that all batches of LED lamps are completely lit, for systems with fixed voltage output of the power supply, the voltage has to be increased to meet high-voltage LEDs. For low-voltage LEDs, the output voltage is also high, and the excess voltage needs The loss is on the circuit; therefore, for a system with a fixed voltage output of the power supply, it leads to waste of power supply and increased power consumption, thereby reducing product reliability

The invention discloses a Mini LED driving system and a driving method thereof. The Mini LED driving system is connected with a plurality of LED lamp sets connected in parallel, and each LED lamp set comprises a plurality of LED lamp strings connected in parallel. The Mini LED driving system comprises a power supply module, a control module, a voltage adjusting module and driving modules corresponding to LED lamp sets in number. The control module outputs brightness information to each driving module; each driving module drives the corresponding LED lamp string in the corresponding LED lamp group to be lightened according to the brightness information; each driving module outputs a corresponding voltage regulation signal to the voltage regulation module; the voltage regulation module controls the output voltage of the power supply module to be in a preset range according to the corresponding voltage regulation signal. The output voltage of the power supply module is adjusted by arranging the voltage adjusting module, so that the power consumption can be effectively reduced, and the reliability of the system is improved.
Description
technical field [0001] The invention relates to the technical field of LEDs, in particular to a Mini LED driving system and a driving method thereof. Background technique [0002] With the continuous advancement of display technology, ordinary LED TVs can no longer meet higher image quality requirements, and LocalDimminig (local backlight adjustment) technology combined with HDR (High-Dynamic Range: high dynamic range image) technology can greatly improve the TV image quality. promote. Mini LED can be simply understood as a miniaturized LED. Thousands of Mini LEDs are used as the backlight, and with Local Dimming technology, each LED can be individually controlled. If the LEDs are small enough and the number is large enough, one LED can be used as a backlight for one pixel, achieving infinite contrast and making a qualitative leap in image quality. [0003] Mini LED generally consists of tens of thousands of LEDs. For cost reasons, people generally do not use a single lamp...
