The current market usually adopts the method of flat cable connection and floating connector connection, which is only suitable for single-sided screen application scenarios. Therefore, the application of LED products is limited. For application scenarios such as multi-sided screens, it is easy to increase the difficulty and cost of installation. Summary of the invention

[0003] In view of the problems of the prior art, the present invention provides an LED receiving system supporting double-sided LED modules, changes the expansion mode of LED modules, improves the current situation in the industry where it is difficult to assemble and display independent double-sided LED modules, and is more conducive to equipment assembly and cost control.

[0004] The specific scheme proposed by the present invention is:

[0005] The present invention provides an LED receiving system supporting double-sided LED modules, comprising an LED receiving card and an LED module. The core board of the LED receiving card is integrated with a HUB board. Two groups of LED modules are arranged at the same position on both sides of the LED receiving card through connectors. The number of LED modules is arranged in the two groups of LED modules according to demand. The LED receiving card arranges two sets of receiving card ICs according to the two groups of LED modules to realize independent control of display images. The receiving card IC uses ICND6603 as a control chip for LED display driving, inputs video through HDMI / DVI, and directly drives the LED module after processing.

[0006] The LED receiving card is powered by a 4.2V voltage level, and uses a DCDC buck chip to adjust the 4.2V voltage to a 3.3V voltage to power the receiving card IC.

[0007] Furthermore, the LED receiving card of the LED receiving system supporting double-sided LED modules extends the input interface signal of ICND6603 to the PCB, transmits data in the form of a network port, and the output signal is divided into a data signal and a control signal, wherein the data signal is the 40 groups of RGB data that can be output by ICND6603, and is directly connected to the connector part via the driver chip 74HC245 to provide the output data signal for the LED module; the control signal is the LED control signal DCLK, GCLK, LE output by ICND6603, the line scanning control signal LINE_A, LINE_B, and other host computer control signals I2C, SPI, etc. Such control signals perform scanning control and clock control on the above data signals, and are directly connected to the connector part via the driver chip 74HC245 to provide the output control signal for the LED module 103.

[0008] Furthermore, the LED receiving card of the LED receiving system supporting double-sided LED modules selects the synchronous buck regulator controller JWH6344 as the DCDC buck chip, and uses the JWH6344 to adjust the 4.2V voltage to 3.3V voltage to power the receiving card IC.

[0009] Furthermore, the LED receiving card of the LED receiving system supporting double-sided LED modules provides multiple input interfaces, including a DVI interface, an HDMI interface, and a VGA interface.

[0010] The present invention also provides an LED receiving method supporting a double-sided LED module, and uses the LED receiving system supporting a double-sided LED module to control an LED display screen.

[0011] In the LED receiving method supporting double-sided LED modules, a signal is received by an LED receiving card: first, a serial data or parallel data signal is received from a sending card or a computer,

[0012] The received signal is decoded and converted into a computer-recognizable format, and the contrast, brightness and chromaticity of the signal are adjusted through the LED receiving card.

[0013] The decoded signal is further processed to meet the display requirements of the LED display, thereby driving the LED display to work normally.

[0014] Furthermore, in the LED receiving method supporting double-sided LED modules, the contrast, brightness and chromaticity of the signal are adjusted by the LED receiving card, including:

[0015] Through the LED receiving card, the receiving card IC is used to control the grayscale, control the LED module, and adjust the grayscale level of the LED display.

[0016] Through the LED receiving card, the receiving card IC is used for color correction, controlling the LED module, and adjusting the color balance and saturation of the LED display.

[0017] The LED receiving card uses the receiving card IC to control the LED module according to the changes in ambient light and automatically adjust the brightness of the LED display to save energy and improve the display effect.

[0018] The present invention also provides an LED receiving device supporting a double-sided LED module, comprising: at least one memory and at least one processor;

[0019] The at least one memory is used to store a machine-readable program;

[0020] The at least one processor is used to call the machine-readable program to execute the LED receiving method supporting a double-sided LED module.

[0021] The benefits of the present invention are:

[0022] In the double-sided layout scenario, the LED modules are simultaneously inserted on the front and back sides of the LED receiving card, achieving the purpose of displaying the double-sided LED module 103 at the same time, which is more conducive to the positioning of the LED module, ensuring that the front and back sides of the LED box have the same display area and display position, and can provide a better viewing effect. The two sets of receiving card ICs independently control the two display screens of the double-sided screen, which is more conducive to identifying the receiving card IC corresponding to the single display screen, and is simpler and easier to use in PCB routing.
