Description

Technical Field

[0001] The present invention relates to the field of 3D display technology, and in particular to a 2D and 3D conversion system for a naked-eye 3D spliced ​​display screen, so that a light field screen can be used in different 2D and 3D scenes. Background Art

[0002] Usually, naked-eye 3D splicing display screens use a matrix method to convert 2D and 3D. Figure 1 As shown in the figure, it is a schematic diagram of a 2×2 spliced ​​screen using a matrix method. This method divides the entire screen into several areas and cuts the image output by the computer according to these areas. Each spliced ​​screen corresponds to an area in the matrix image, for example, spliced ​​screen 1 corresponds to matrix image area 1, spliced ​​screen 2 corresponds to matrix image area 2, and so on. When displaying a 2D image, the computer outputs 2D data; when displaying a 3D image, it outputs 3D data. Although this method is more convenient to use, as the number of spliced ​​screens increases, the requirements for data processing capabilities also increase, resulting in an increase in equipment costs.

[0003] Therefore, although naked-eye 3D spliced ​​display screens have been widely used in the display field and provide a convenient experience of watching 3D images without 3D glasses, the current matrix conversion method has the problem of increasing data processing capabilities as the number of spliced ​​screens increases, which leads to increased equipment costs. Summary of the invention

[0004] The object of the present invention is to provide a 2D and 3D conversion system for a naked-eye 3D splicing display screen, so as to solve the technical problem that the existing splicing device has high equipment cost when processing large-volume 3D information sources.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of a 2D and 3D conversion system of a naked-eye 3D splicing display screen of the present invention is as follows:

[0006] A 2D and 3D conversion system for a naked-eye 3D splicing display screen, comprising:

[0007] A display driver card, the card is equipped with at least two signal source input ports, namely a first signal source input port and a second signal source input port, for receiving 3D and 2D display signals respectively. In addition, the driver card is also equipped with a communication serial port for receiving control signals from a control computer;

[0008] The computer is responsible for outputting 2D and 3D display signals and sending control signals. When 3D content needs to be displayed, the 3D display signal is sent to the first signal source input port; when 2D content needs to be displayed, the 2D display signal is sent to the second signal source input port through the splicer. The computer also sends a switching signal through the serial port to instruct the display driver board to switch between the two display modes;

[0009] The splicer receives the 2D display signal from the control computer and distributes it to the second signal source input port of the display driver board to achieve 2D display.

[0010] The computer is responsible for managing and outputting 2D and 3D display signals, and instructs the display driver board to switch between the two display modes through control signals. When 3D content needs to be displayed, the system directly sends the 3D display signal to the first source input port, and when 2D content needs to be presented, the 2D display signal is distributed to the second source input port through the splicer. This optimized design makes the entire operation process more intuitive and simple. At the same time, by distributing the 2D signal to the second source input port, the system avoids overly complex matrix conversion, thereby reducing data processing and equipment requirements. Compared with the traditional matrix method for 2D and 3D conversion, this optimization solution not only reduces the cost of the system, but also improves its efficiency and ease of use.

[0011] Furthermore, the control computer directly outputs the 2D display signal to the splicer to simplify the signal transmission link, improve the signal transmission efficiency and reduce the delay.

[0012] Furthermore, the 2D and 3D conversion system also includes a distributor, which is used to receive a 2D display signal from a control computer or a spliced ​​display screen and output the signal to the splicer to achieve synchronous 2D display of multiple display screens.

[0013] Furthermore, the display driver boards are connected in series through their serial communication modules, thereby achieving communication between multiple display screens, allowing a single control signal to be transmitted coherently, and ensuring that the display modes of all display screens are switched uniformly.

[0014] The 2D and 3D conversion system of the naked-eye 3D splicing display screen provided by the present invention has the following advantages:

[0015] The 2D and 3D conversion system of the naked-eye 3D splicing display screen optimizes the processing flow of 2D and 3D signals. The computer is responsible for outputting 2D and 3D display signals and sending control signals to command the display driver board to switch between the two display modes according to the display requirements. When 3D content needs to be displayed, the 3D display signal is directly sent to the first source input port; when 2D content needs to be displayed, the 2D display signal is distributed to the second source input port through the splicer. The 2D signal is distributed to the second source input port through the splicer, and the splicer is no longer used to process 3D data, which simplifies the entire operation process. Compared with the traditional matrix method for 2D and 3D conversion, this optimization solution is relatively simple in data processing and equipment requirements, avoids the need for a complex matrix conversion system, and reduces the cost of the system. In general, this system architecture is simple and efficient, providing a more convenient and economical solution for the application of naked-eye 3D splicing display screens.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] See also Figure 2The present invention provides a 2D and 3D conversion system for a naked-eye 3D splicing display screen, which adopts a 2D and 3D separation scheme to reduce the requirements for equipment and the switching cost. The 2D and 3D signals adopt a two-way display method. When the splicing screen needs 3D display, the computer sends a control signal, and the splicing screen board switches to the 3D signal source receiving port after receiving the control signal, ready to receive the 3D signal source, the computer sends a 3D signal source, and the splicing screen displays 3D; when the splicing screen needs 2D display, the computer sends a control signal, and the splicing screen board switches to the 2D signal source receiving port after receiving the control signal, ready to receive the 2D signal source, the computer sends a 2D signal source, and the 2D display sequence is allocated by the splicer and then output to the splicing screen to display 2D. 3D is realized by adding computers instead of using a screen splitter, and each computer outputs a signal to a single or several splicing screen displays, and 3D display is realized by signal control and synchronization of computer software. This method avoids the disadvantages of high equipment requirements and high costs after the number of splicing screens increases, and the inability to achieve unlimited splicing.

[0022] When using the traditional solution, 2D signal data is output when displaying 2D, and 3D source data is output when displaying 3D. All data is processed by the splicer.

[0023] In this solution, the computer directly outputs the 3D signal source to the first signal source interface of the display screen. When the computer processes the 3D signal source, it splits the 3D signal source data in the process of generating 3D signal source data to adapt to the splicing of each screen. The 2D information is a signal that needs to be divided into each splicing screen to be combined into a complete picture, so a screen splitter is needed for segmentation. The computer itself has strong data processing capabilities, and if the splicer processes the 3D signal source data, it will cause high hardware costs.

[0024] See also Figure 3 , is a schematic diagram of the connection method of the signal source. The driver board of the spliced ​​screen display has at least two signal source input ports (such as HDMI1 and HDMI2), that is, each driver board has a first signal source input port and a second signal source input port, and the computer directly outputs multi-channel 3D signal source data to the first signal source port of each driver board.

[0025] The distributor copies the signal of one display screen and decides whether to copy the signal to the splicer according to the need. It is required for 2D display. At this time, the signal is a 2D signal source and the copied signal is the 2D signal of one of the display screens. It is not required for 3D display only. At this time, the signal source is a 3D signal source.

[0026] For example, a 2D signal is copied from the video output port of a display to the splicer. The spliced ​​screen outputs the signal in the display order and distributes it to the signal source 2 port (the second signal source input port) of the spliced ​​screen. When the spliced ​​screen is 2D, the displayed content is the 2D content of the upper left corner display screen.

[0027] If a distributor is not used, the computer can directly output a signal to the splicer to display any 2D content (then 2D / 3D switching cannot be achieved, and only any 2D content can be displayed).

[0028] See also Figure 4 Each driver board of the splicing screen display has a pair of serial communication modules, preferably RS232 modules, wherein the serial communication module of one driver board is connected to the computer, and the serial communication modules between the other driver boards are connected in series.

[0029] The 2D and 3D conversion system of the naked-eye 3D splicing display screen provided by the present invention has the following advantages:

[0030] The computer is responsible for outputting 2D and 3D display signals and sending control signals. When 3D content needs to be displayed, the 3D display signal is sent to the first signal source input port; when 2D content needs to be displayed, the 2D display signal is sent to the second signal source input port through the splicer. The computer sends a switching signal through the serial port to instruct the display driver board to switch between the two display modes;

[0031] The splicer receives the 2D display signal from the control computer and distributes it to the second signal source input port of the display driver board to achieve 2D display.

[0032] The entire operation process is simplified by distributing the 2D signal to the second source input port through the splicer. The splicer is no longer used to process 3D data, which simplifies the data processing and equipment requirements compared to the traditional matrix method for 2D and 3D conversion. By distributing the 2D signal to the second source input port, the need for a complex matrix conversion system is avoided, thereby reducing the cost of the system.

[0033] The display driver board and the computer interact through the communication serial port, which can achieve more efficient data transmission and control. It helps to improve the overall efficiency of the system, make signal transmission more stable and reliable, and reduce potential failures and delays.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
