[0030] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings rather than all the structures.

[0031] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts depict the steps as sequential processes, many of the steps can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operations are completed, but it can also have additional steps not included in the drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, and so on.

[0032] Embodiment 1

[0033] Figure 1 The flowchart of the text program display method for the LED display screen provided by Embodiment 1 of the present invention is shown. This embodiment is applicable to the situation of controlling the LED display screen to display text programs using new fonts. This method can be executed by the text program display device of the LED display screen provided by the embodiments of the present invention, and this device can be implemented in a hardware and / or software manner and is generally integrated in a computer device.

[0034] As Figure 1 shown, it specifically includes the following steps:

[0035] S11. Obtain the edited target text program and the selected target control card.

[0036] S12. If the target text program uses a new font other than the built-in font of the target control card, draw a target picture according to the target text program and the screen parameters of the target LED display screen matching the target control card, and generate picture information of the target picture.

[0037] S13. Send the picture information to the target control card so that the target control card controls the target LED display screen to display according to the picture information.

[0038] Specifically, the text program display method for the LED display screen provided by this embodiment can be implemented by a correspondingly developed system. The user can select the target text program to be sent and the specified target control card from the currently saved and edited text programs through the system interaction interface. Among them, the target text program can be in html format. When uploading various font files to the system, the corresponding font names can be marked, and during the process of editing the text program, the required font name can also be selected from the existing font names for the edited text content. Then, after determining the target text program and the target control card, it can be automatically determined whether the target text program uses a new font other than the built-in font of the target control card, and the built-in fonts of each control card can be pre-stored in the local system.

[0039] If a new font other than the built-in font of the target control card is used in the target text program, a target picture can be drawn according to the target text program and the screen parameters of the target LED display that matches the target control card, and picture information of the target picture can be generated. Specifically, call parameters can be generated according to the target text program and the screen parameters of the target LED display, and the call parameters can be used to call the background drawing interface for drawing. Optionally, the target text program includes text content and font name, and the screen parameters of the target LED display include screen width and screen height. Correspondingly, the call parameters can include the target text program in html format (including text content and font name) and the screen width and screen height of the target LED display, etc., so that the new font is reflected in the form of a picture, and the drawn target picture can adapt to the resolution of the target LED display.

[0040] After generating the picture information of the target picture, the picture information is sent to the target control card, and at the same time, the original target text program can also be sent to the target control card, so that when the target control card receives the sent target text program, it can judge whether it also receives the picture information. When it is determined that the picture information is received, the target LED display is controlled to display according to the picture information, instead of drawing by itself.

[0041] Optionally, the picture information includes the hyperlink of the target picture; correspondingly, the step of enabling the target control card to control the target LED display to display according to the picture information includes: enabling the target control card to download the target picture according to the hyperlink and control the target LED display to display according to the target picture. In addition, the picture information can also only include the target picture content and can be sent to the target control card in the form of a picture format file. Then, the target control card can also control the target LED display to display the target picture when receiving the picture information.

[0042] Further optionally, the picture information further includes an md5 value and / or the size of the target picture, which is used to verify the target picture downloaded by the target control card, so that the correctness of the picture to be controlled and displayed by the target control card can be ensured through the consistency of the md5 value and / or the size of the target picture. Specifically, the target LED display can be controlled to display the target picture after the verification passes.

[0043] On the basis of the above technical solution, optionally, after obtaining the edited target text program and the selected target control card, it further includes: if no new font other than the built-in font of the target control card is used in the target text program, directly send the target text program to the target control card, so that the target control card controls the target LED display to display according to the target text program.

[0044] Specifically, if no new font other than the built-in font of the target control card is used in the target text program, the target text program in the original html format can be directly sent to the target control card. So that when the target control card receives the sent target text program, it can judge whether it also receives picture information. When it is determined that no picture information is received, it can draw the content to be displayed by itself according to the target text program and control the target LED display to display.

[0045] On the basis of the above technical solution, optionally, the method further includes: when editing a text program, every time a character is received, draw the current picture according to the current latest text program and the screen parameters of the simulation screen, and control the simulation screen to display the current picture in real time.

[0046] Specifically, the simulation screen can be a simulation window set on the local machine screen, which is used to simulate the display state of the edited text program on the LED display. During the process of editing the text program, every time a character is input, the background drawing interface can be called once to draw the corresponding current picture for the entire latest text program being edited. Among them, the call parameters are similar to the above, that is, they can be the screen width and height of the simulation screen, and the current latest text program in html format (including text content and font name). The screen width and height of the simulation screen can be set with reference to the actual LED display. Correspondingly, every time a current picture returned by the background is received, the current picture can be displayed in real time through the simulation screen, or every time a hyperlink of a current picture returned by the background is received, the current picture is obtained according to the hyperlink and displayed in real time through the simulation screen. Thus, the display state of the text program can be previewed in real time during the editing process, especially for text programs using new fonts. After the editing is completed, the edited text program can be saved locally for the user to select and use later.

[0047] The technical solution provided by the embodiments of the present invention first obtains the edited target text program and the selected target control card. If a new font other than the built-in font of the target control card is used in the target text program, a target picture is drawn according to the target text program and the screen parameters of the target LED display screen matched with the target control card, and the picture information of the target picture is generated. Then, the picture information is sent to the target control card so that the target control card controls the target LED display screen to display according to the picture information. By drawing the text program as a picture for the LED control card to control the display when there is a new font in the text program to be sent, the new font can be conveniently and quickly applied to the text program and the LED display screen can be controlled to display without operating the device.
