[0041] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0042] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Example 1

[0044] See also Figures 1 to 3 The present invention discloses an LED multi-sided display control method for enabling an LED display control mainboard to perform multi-sided display. The LED display control mainboard includes a first surface and a second surface. A first LED array is arranged on the first surface, and a second LED array is arranged on the second surface.

[0045] The method comprises the following specific steps:

[0046] S1, obtaining a control signal from an external control device and analyzing the control signal to generate an input signal.

[0047] Specifically, the external control device may be a receiving board for transmitting control signals and other data such as video data.

[0048] Specifically, step S1 includes:

[0049] S11 , decoding the control signal and identifying the original signal format and control instructions, and converting the original signal format into a parallel data format.

[0050] In this embodiment of the present invention, after the interface circuit on the LED display control mainboard receives a control signal from an external control device, it needs to perform preliminary decoding of the control signal through a decoding chip, identifying information such as video data and control instructions contained in the control signal. The decoding chip then converts the original signal format into a parallel data format that can be processed within the display panel. For example, the decoding chip converts a video signal based on a network protocol into a digital signal suitable for processing by the internal logic circuit, allowing subsequent signal processing to proceed smoothly.

[0051] S2, synchronously generating and outputting a first display signal and a second display signal based on the input signal.

[0052] Specifically, step S2 includes:

[0053] S21, buffers the input signal temporarily.

[0054] In an embodiment of the present invention, the input signal after decoding and format conversion is temporarily stored in the signal buffer on the LED display control mainboard, which can avoid signal loss or confusion caused by problems such as mismatch in signal transmission speed during the signal distribution process, and provide a stable signal source for subsequent accurate distribution.

[0055] S22 , identifying a first display signal associated with the first surface and a second display signal associated with the second surface in the input signal.

[0056] S23 , establishing a first signal channel and a second signal channel, and synchronously outputting a first display signal and a second display signal through the first signal channel and the second signal channel.

[0057] In this embodiment of the present invention, the distribution logic circuit on the LED display control motherboard precisely distributes the buffered signals based on the display requirements of the first and second surfaces. It identifies the display signals associated with the first and second surfaces and directs them to the corresponding first and second signal channels, respectively. By distributing the display signals for different surfaces and synchronously outputting them through the corresponding signal channels, the timing and content of the signals on both surfaces are highly consistent, supporting stable dual-sided display.

[0058] It should be understood that the first surface and the second surface can be any surface on the display panel, and the LED display control mainboard also includes several other surfaces. It can identify the control instructions in the control signal based on different display requirements, and then distribute the input signal into several groups of display signals not limited to the first display signal and the second display signal, and then output them synchronously through the corresponding signal channels to drive the LED arrays on each surface to emit light and realize the display requirements of different surfaces.

[0059] In some embodiments, before establishing the first signal channel and the second signal channel, the method further includes:

[0060] Enhancing the driving capability of the first display signal and the second display signal includes increasing the voltage and current intensity of the first display signal and the second display signal.

[0061] It is understandable that since the signal will attenuate to a certain extent during the transmission process, increasing the voltage and current strength of the signal through the driving circuit is conducive to ensuring that the signal can be transmitted reliably, thereby driving the first LED array and the second LED array on the LED display control mainboard to emit light, solving the problem of insufficient signal strength during long-distance transmission or multi-module connection.

[0062] S3, driving the first LED array and the second LED array to emit light based on the first display signal and the second display signal respectively.

[0063] Specifically, step S3 includes:

[0064] S31 , performing signal adaptation on the first display signal and the second display signal respectively with the first LED array and the second LED array, where the signal adaptation includes matching pin definition specifications and electrical characteristics.

[0065] It can be understood that by rearranging and defining the signal pins of the first display signal and the second display signal according to the interface requirements of the first LED array and the second LED array, and adjusting the signal level, impedance and other electrical parameters to make them fully compatible with the first LED array and the second LED array, it is helpful to ensure that the signal is transmitted accurately.

[0066] S32: Transmit the adapted first display signal and second display signal to the display panel, and drive the first LED array and the second LED array to emit light based on the control instructions of the first display signal and the control instructions of the second display signal, respectively.

[0067] By driving the LEDs in the first and second LED arrays to emit light according to the signal, a double-sided display effect is achieved. Whether the display content is on the front or back, it can be presented clearly and stably, meeting the requirements of double-sided display in practical applications.

[0068] In the present invention, by obtaining a control signal from an external control device, parsing the control signal and generating an input signal, and then synchronously generating and outputting a first display signal and a second display signal based on the input signal, the first LED array and the second LED array arranged on the first surface and the second surface of the same mainboard are driven to emit light based on the first display signal and the second display signal, respectively. This can achieve multi-sided display on a single mainboard without the need to use multiple mainboards for multi-sided display, solving the problems of large space occupation, complex wiring, high power consumption and uneven heat dissipation caused by stacking multiple mainboards during multi-sided display, and is also beneficial to improving the synchronization accuracy of the display signal.

[0073] The driving display module 203 is used to drive the first LED array and the second LED array to emit light based on the first display signal and the second display signal respectively.

[0074] In some embodiments, synchronously generating and outputting a first display signal and a second display signal based on an input signal includes:

[0075] Buffers temporarily store input signals.

[0076] A first display signal associated with the first surface and a second display signal associated with the second surface are identified in the input signal.

[0077] A first signal channel and a second signal channel are established, and a first display signal and a second display signal are synchronously outputted through the first signal channel and the second signal channel.
