Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] like figure 1 As shown, a method for complex layout and wiring compatible with LED displays includes the following steps:

[0026] (1) Read in the relevant LED basic parameters input by the user through the wizard, and determine the technical parameters of the LED unit board;

[0027] (2) Instruct the LED display to turn on or off, and detect the data polarity of the LED unit board;

[0028] (3) Instruct the LED display screen to light up or darken, and detect the blanking polarity of the LED unit board;

[0029] (4) Instruct the LED display to display red, green, and blue colors, detect the interface color sequence of the LED unit board, and determine whether color exchange is required;

[0030] (5) Instruct the LED display screen to display a line of information, and detect the scanning (static) type and the number of times of reentry of the LED unit board;

Abstract

The invention relates to a method for complex layout and wiring compatible with an LED display screen, comprising the steps as follows: technical parameters of an LED unit plate are determined; data polarity of the LED unit plate is detected; blanking polarity of the LED unit plate is detected; the interface color sequence of the LED unit plate is detected; scanning type and returning times of the LED unit plate is detected; offset point of continuous position is continuously sent, practical display position of all offset points is read and point mapping relationship table of the LED unit plate is generated; the point mapping relationship table is sent to the control system of the LED display screen; the control system of the LED display screen memorizes the point mapping relationship table and reads in the memory; when data is required for display, practical address is gained by table look-up and the address is written in the FPGA address space of the control system; the FPGA receives the CPU data of the control system and generates logical display values. The method disengages the tie that the LED display screen factory designs the LED unit plate wiring, further reduces the cost, and is compatible with the wiring of hundreds of screen bodies, more especially with the irregularly random pixel points.

Description

technical field [0001] The invention relates to LED display technology, in particular to a method compatible with complex layout and wiring of LED display screens. Background technique [0002] LED: semiconductor light-emitting diode, widely used in the working status indication of many electrical appliances, the light emitted mainly includes red, green, blue, yellow, and white; LED unit board: a fixed-sized dot matrix module composed of LEDs, usually with different width and height It is composed of 8×8, 16×8, 16×16, 32×32, 64×32 and other pixel modules, which can adapt to any screen size; there are single-color, two-color and full-color screens; LED display: use The LED unit boards are spliced ​​into the size that needs to be displayed to display various texts, pictures, videos and other information. The outstanding feature that is different from LCD (liquid crystal) or CRT (picture tube) TV is that it can display large size and high brightness. It is usually used for Inf...
