Abstract

The invention discloses an LED display screen energy saving method and device, equipment and a storage medium. The method comprises the steps of collecting display data; updating the display data of the next line when the line scanning period enters the shadow elimination time, and calculating the signal pulse width of the display data in each column driving signal of the next line at the shadow elimination time, wherein the vanishing time is a time slot between line scanning pulses of adjacent line scanning signals; judging the working mode of the driving circuit of the column driving module corresponding to each column driving signal based on the signal pulse width, and adjusting the driving circuit of the column driving module corresponding to each column driving signal according to the working mode. Compared with the prior art that the energy-saving mode can be triggered only when the next frame of data is all-zero data, the signal pulse width of the display data in each column driving signal is judged in the vanishing time, the starting frequency of the energy-saving mode of the column driving module in the row scanning period is increased, and therefore the energy-saving efficiency of the LED display screen is improved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to an LED display screen energy-saving method, device, equipment and storage medium. Background technique [0002] In recent years, in the field of LED display screens, LED is used as the basic light-emitting device of various light-emitting devices. The large-area display screen composed of dot matrix modules or pixel unit modules composed of LEDs has high reliability, long service life and environmental adaptability. With the characteristics of strong capability, high price-performance ratio, and low cost of use, it has rapidly grown into a mainstream product of flat panel display in just a decade, and has been widely used in the field of information display. [0003] With the continuous development of display technology, the requirements for display screens are getting higher and higher. In order to meet the needs of low power consumption of the display screen, LED driver chip...
