Embodiment 1

[0034] In order to solve the technical problem that the existing LED display screen driving method cannot meet the requirements of higher and higher pixel density and driving data volume, this embodiment provides a driving method for an LED display screen. The method is suitable for an LED display drive system. Please refer to figure 1 , figure 1 It is a flowchart of a method for driving an LED display screen provided by an embodiment of the present invention. The method includes:

[0035] Step S1: Receive the grayscale weights of the display data, and generate a refresh data stream for driving the lamp beads based on the grayscale weights according to the preset grayscale weight refresh order, and the refresh data streams are based on different grayscales. The degree weight is divided into a plurality of gray-scale weight bits, and each of the gray-scale weight bits corresponds to more than one subframe;

[0036] Step S2, configure the corresponding dynamic current for th...

Embodiment 2

[0141] An embodiment of the present invention further provides an LED display screen, the LED display screen includes a memory, a processor, and a computer program stored on the memory and executable on the processor, the computer program being executed by the processor When executed, the steps of the method for driving the LED display screen described in the first embodiment above are realized.

[0142] The LED display screen of the embodiment of the present invention and the method of the above-mentioned first embodiment belong to the same concept, and the specific implementation process is detailed in the corresponding method embodiment, and the technical features in the method embodiment are all applicable to the LED display screen embodiment of the present invention. , which will not be repeated here.

Embodiment 3

[0144] Embodiments of the present invention further provide a computer-readable storage medium, where an LED display screen driver is stored on the computer-readable storage medium, and when the LED display screen driver is executed by a processor, the LED display in the first embodiment above is realized The steps of the screen driving method.

Abstract

The invention discloses an LED display screen driving method, an LED display screen and a storage medium, and belongs to the technical field of display control, and the LED display screen driving method comprises the following steps: receiving a gray weight of display data, and generating a refreshing data stream for driving lamp beads according to a preset gray weight refreshing sequence based on the gray weight, the refresh data stream is divided into a plurality of gray scale weight bits according to different gray scale weights, and each gray scale weight bit corresponds to more than one subframe; configuring a corresponding dynamic current for the to-be-refreshed subframe; and when a line tube conduction signal corresponding to the lamp bead is received, driving the lamp bead according to the refreshing data stream and the dynamic current corresponding to the to-be-refreshed sub-frame. The gray scale of the lamp bead is defined from the two dimensions of the instantaneous driving current and the refreshing data flow, so that the driving efficiency of the lamp bead is greatly improved, the time required for realizing the corresponding gray scale is shortened, and the driving data volume burden is reduced.

Description

technical field [0001] The invention relates to the technical field of display system control, in particular to a driving method of an LED display screen, an LED display screen and a storage medium. Background technique [0002] The LED display uses the direct light emission of LED lamp beads to display content. Each pixel on the screen contains a red lamp bead, a green lamp bead and a blue lamp bead. To achieve different brightness and color display of pixels, it is necessary for the three lamp beads to have different brightness ratios. For each lamp bead, its different brightness is achieved by grayscale refresh, which is also the working basis of the constant current driver chip that drives the LED lamp bead to emit light. [0003] As the pixel density of LED displays is getting higher and higher, the load capacity of constant current chips cannot keep up with the development speed of LED displays. Usually, a constant current chip can carry 512 lamp beads (typical value...
