Problems solved by technology

[0003] In the existing technical solutions, the reading efficiency of the off-chip memory is too low, and the image data read each time is too small, and it is basically impossible to read in bursts. The method of clock frequency or increasing the bit width has higher cost and more restrictions

Embodiment Construction

[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] Currently, the number of LED driver chips that can be controlled is limited. One LED driver chip can only control the LED lights in row V and column H. H is the maximum data channel of the LED driver chip, which needs to be lit by cascading many LED driver chips. A whole box of LED lights. In the vertical direction, the box is divided into K equal parts, and the number of row...

Abstract

The invention provides an image data reading method, device, electronic equipment and readable storage medium, relates to the technical field of LED image display, including storing each row of image data in each row of image blocks into v storage blocks, each Storage block h rows, wherein the data of each row includes the image data of the same position of each group in the same row of each image block; each storage block is output in the following way in turn: read the image of each row sequentially in longitudinal order data, and output the image data at the same position at the same time. On the basis of not changing the hardware read and write clock frequency or increasing the bit width, the burst reading method is adopted to shorten the image data in the off-chip memory of the LED driver chip. read time.

Description

technical field [0001] The invention relates to the technical field of LED image display, in particular to an image data reading method, device, electronic equipment and readable storage medium. Background technique [0002] One side of the small-pitch LED display is composed of an indefinite number of cabinets spliced ​​together, and one cabinet is covered with LED lights. The receiving card inserted in the cabinet controls the display of the line scan chip and the LED driver chip to drive the LED lights, and the image displayed on the cabinet is sent to the cabinet receiving card line by line by the source sending card. Because the on-chip memory resource of the main control chip of the receiving card is limited, generally the image needs to be stored in the off-chip memory. When transmitting image data to the LED driver chip, read the required image data from each part of the image one by one. Then send them to the LED driver chip together. [0003] In the existing tec...
