Embodiment 1

[0020] Such as figure 1 As shown, the LED display screen is composed of a display module with 80×80 pixels; the inherent number of scanning lines of the scanning device is 32 lines. For cost considerations, the number of basic scanning lines should be as close to 32 as possible. 80 / 32=2.5≈3, so the display module should be divided into 3 scanning areas. In this way, the problem that the number of scanning lines of 80 / 3=26.7 lines is not an integer appears. Therefore, the number of basic scanning lines is selected as 27 for line scanning. In this way, 81 lines of scanning appear on the display module of 80×80 pixels. For the first and second scanning areas, each frame is scanned according to the number of basic scanning lines of 27; for the third scanning area, a blank line is inserted in the last line, and each frame is scanned according to the number of effective display lines of 26; in this way, the actual effective The number of scan lines matches the number of image lin...

Embodiment 2

[0022] Such as figure 2 As shown, the LED display screen is composed of a display module with 79×79 pixels; the inherent number of scanning lines of the scanning device is 32 lines. Considering the cost, the number of basic scanning lines should be as close as possible to 32. 79 / 32=2.47≈3, so the display module should be divided into 3 scanning areas. In this way, the problem that the number of scanning lines of 79 / 3=26.3 lines is not an integer appears. Therefore, the number of basic scanning lines is selected as 27 for line scanning. In this way, 81 lines of scanning appear on the display module with 79×79 pixels. For the first scanning area, each frame is scanned according to the number of basic scanning lines of 27; for the second and third scanning areas, a blank line is inserted in the last line, and each frame is scanned according to the number of effective display lines of 26; in this way, the actual effective The number of scan lines matches the number of image li...

Embodiment 3

[0024] Such as image 3 As shown, the LED display screen is composed of a display module with 80×80 pixels; the inherent number of scanning columns of the scanning device is 32 columns. For cost considerations, the number of selected basic scanning columns should be as close to 32 as possible. 80 / 32=2.5≈3, so the display module should be divided into 3 scanning areas. In this way, the problem that the number of scanned columns of 80 / 3=26.7 columns is not an integer appears. Therefore, the number of basic scanning columns is selected as 27 for column scanning. In this way, 81 columns of scans appear on the display module with 80×80 pixels. For the first and second scanning areas, each frame is scanned according to the number of basic scanning columns of 27; for the third scanning area, an empty column is inserted in the last column, and each frame is scanned according to the number of effective display columns of 26; this is actually effective The number of scan columns matc...

Abstract

The invention relates to a scanning row number or column number unmatched LED display screen scanning display method. According to the method, the integral multiple of the row number or the column number of basic scanning is selected to be greater than the actual row number or the column number of the image required to be displayed by the display module. Then the scanning row number or column number is greater than the effective display row number or column number, one or multiple extra rows of the scanning area are defined as vacant rows and one or multiple extra columns of the scanning areaare defined as vacant columns. Image transmission is performed according to the actual effective display row number or column number in case of image transmission and scanning of the scanning row number or column number is performed according to the row number or the column number greater than the effective display row number or column number. The vacant rows has no physical hardware support and do not participate in image displaying. Continuous image splicing can be guaranteed, and scanning the vacant rows or the vacant columns has no physical row and column support and does not perform displaying so that scanning the vacant rows or the vacant columns does not influence display integrity and continuity.

Description

Technical field: [0001] The invention belongs to the technical field of dot-matrix display screens, and relates to scanning and display methods of dot-matrix display screens, in particular to a scanning display method of an LED display screen when the number of scanning rows or columns does not match a display module. Background technique: [0002] All current dot-matrix displays are composed of M*N pixels and can display images of M*N real pixels. In terms of specific display methods, M*N pixels are usually decomposed into several basic scanning areas with m columns and n rows (or m rows and n columns), and m columns (or rows) are scanned in the basic scanning area, or Scan by n rows (or columns). Only the case of scanning n rows (or columns) will be described below, and the scanning of m columns (or rows) is actually the same. [0003] N rows (or columns) scanning limits the structure of the basic unit - the composition of the display module. The number of rows (or colu...
