Simulation clock display method and device and LED display control card

Abstract

The invention relates to a simulation clock display method and device and an LED display control card. The method comprises the steps of acquiring time-pointer-free dial plate data, acquiring the position coordinate data of at least one time pointer according to the current time, obtaining corresponding time pointer graphic data according to the position coordinate data of each time pointer, integrating the time pointer graphic data with the time-pointer-free dial plate data to obtain simulation clock data, and driving and controlling an LED display screen to display a simulation clock corresponding to the current time according to the simulation clock data. Therefore, the size of data sent to an LED display control card by upper computer software can be reduced greatly, the efficiency of communication between software and hardware can be improved greatly, and the storage load of the LED display control card can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an analog clock display method, an analog clock display device and an LED display control card. Background technique [0002] In the asynchronous control system of LED single and double color display, the media content to be displayed on the display is configured by the user through the host computer software according to their own needs; the host computer sends the media data to the single and double color control card (can Send through serial port, U disk, Ethernet, WiFi, etc.), and then process the data with special effects through the single and double color control card and convert it into the same data format as the display screen used by the user, and output the data to the display screen for display. [0003] Analog clock is an indispensable medium in the field of LED single and double color display, such as figure 1 As shown, the dial is divided into 12 large divisions...

AI Technical Summary

Problems solved by technology

[0007] (1) It greatly increases the time for the host computer to send data to the single and double color control card, especially when the user uses the serial port communication, the data sending time may be as long as tens of seconds or even several minutes, which greatly reduces the user experience;

[0008] (2) The amount of data received by the single-color control card will be very large, occupying a lot of flash memory (Flash) space, which will seriously affect the data storage space of other media, so that the amount of programs is greatly limited
