Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display system and display device. Background Technology

[0002] In the driving scheme of a traditional active matrix LED (Light Emitting Diode) display system, multiple LED panels operate simultaneously in the display system. Each independent LED panel contains a matrix composed of pixel units and a driver integrated circuit for driving these pixel units.

[0003] To ensure the proper functioning of the display system, the central control unit (e.g., the receiver card) must provide two types of signals with different properties and timings to these driver integrated circuits. The first type is the address configuration signal required by the display system during the initialization phase, and the second type is the image data signal continuously transmitted by the display system during the normal display phase. To avoid crosstalk or timing conflicts between the critical address configuration signal and the high-frequency image data signal, existing technologies generally use independent, physically separated signal lines and input / output ports to transmit these two types of signals separately.

[0004] As the resolution of the LED panels increases and the number of LED panels in the display system grows, the total number of pixel units, the number of driver integrated circuits, and the corresponding number of signal lines in the display system all increase dramatically. This surge in the number of signal lines puts enormous pressure on the input / output port resources of the receiver cards. When the number of signal lines reaches a certain point, it becomes necessary to increase the number of receiver cards to meet the input / output port requirements of the current signal lines.

[0005] It is evident that for high-resolution, multi-lamp display systems, multiple receiver cards may be required to meet control requirements. When multiple receiver cards are present, the display system will face problems such as inconvenient receiver card control and signal conflicts, leading to a decrease in the reliability of the display system. Summary of the Invention

[0006] Therefore, it is necessary to provide a display system and display device to improve the reliability of high-resolution, multi-lamp display systems.

[0007] In a first aspect, embodiments of this application provide a display system, including:

[0008] Multiple light panels, each light panel comprising a pixel unit matrix;

[0009] Multiple first shared data lines, with one of the light boards connected to at least one of the first shared data lines;

[0010] Multiple second shared data lines;

[0011] The selection module is connected between the first shared data line and the second shared data line;

[0012] The control module is connected to the selection module, the light panel, and the second shared data line;

[0013] The control module is configured as follows:

[0014] Sending display signals or recording signals via the second shared data line; and,

[0015] A control signal is sent to the selection module and the target light board to control the selection module to conduct the first shared data line connected to the second shared data line and the target light board, and to control the target light board to establish a display signal path or a recording signal path connected to its pixel unit matrix inside, so as to transmit the display signal to the target light board through the display signal path, or transmit the recording signal to the target light board through the recording signal path.

[0016] In one embodiment, the light panel includes an integration unit, wherein:

[0017] The first end of the integration unit is connected to the pixel unit matrix, the second end of the integration unit is connected to the first shared data line, and the control end of the integration unit is connected to the control module.

[0018] The integration unit is used to connect the first shared data line to the display signal path or connect the first shared data line to the recording signal path according to the control signal sent by the control module.

[0019] In one embodiment, the pixel unit matrix includes multiple display data lines and multiple recording data lines, the display signal path is composed of one of the display data lines and the recording data lines, and the recording signal path is composed of the other of the display data lines and the recording data lines.

[0020] In one embodiment, the control signal includes a first control signal, and the integration unit includes a first transceiver and a second transceiver, wherein:

[0021] The first signal transceiver includes multiple first terminals, multiple second terminals, and a control terminal. Each first terminal of the first signal transceiver is connected to each of the display data lines in the pixel unit matrix. Each second terminal of the first signal transceiver is connected to each of the first shared data lines. The control terminal of the first signal transceiver is connected to the control module. The first signal transceiver is used to turn on its first and second terminals upon receiving the first control signal.

[0022] The second transceiver includes multiple first terminals, multiple second terminals, and a control terminal. Each first terminal of the second transceiver is connected to each of the recording data lines in the pixel unit matrix. Each second terminal of the second transceiver is connected to each of the first shared data lines. The control terminal of the second transceiver is connected to the control module. The second transceiver is used to turn on the first and second terminals of the first transceiver when it receives the first control signal.

[0023] In one embodiment, the control signal includes a second control signal, and the selection module includes a plurality of third transceivers, the number of which is equal to the number of the light panels, wherein:

[0024] Each of the third transceivers corresponds one-to-one with each of the lamp boards. The first end of the third transceiver is connected to the first shared data line connected to the corresponding lamp board, the second end of the third transceiver is connected to the second shared data line, and the control end of the third transceiver is connected to the control module. The third transceiver is used to conduct its first and second ends when it receives the second control signal, so as to conduct the second shared data line to the first shared data line connected to the target lamp board.

[0025] In one embodiment, the control signal includes a second control signal, and the selection module includes a multiplexer, wherein:

[0026] The multiplexer includes multiple input channels, multiple output channels, and a control terminal. Each output channel of the multiplexer is connected to the first shared data line connected to different lamp boards. Each input channel of the multiplexer is connected to each of the second shared data lines. The control terminal of the multiplexer is connected to the control module. The multiplexer is used to connect its input channels and the output channels indicated by the second control signal according to the second control signal, so as to connect the second shared data line to the first shared data line connected to the target lamp board.

[0027] In one embodiment, the number of the first shared data lines connected to one of the integration units is equal to the greater of the number of display data lines connected to the integration unit and the number of recording data lines.

[0028] In one embodiment, the number of the second shared data lines is equal to the maximum of the number of display data lines and the number of recording data lines in each of the pixel unit matrices.

[0029] In one embodiment, the control module is further configured to:

[0030] When controlling the target light board to establish the display signal path, the target light board is controlled to disconnect the recording signal path; and when controlling the target light board to establish the recording signal path, the target light board is controlled to disconnect the display signal path.

[0031] In a second aspect, this application provides a display device, including a housing and a display system according to any one of the first aspects above.

[0032] The aforementioned display system and device, firstly, separates the transmission of display signals from the transmission of recording signals within the lamp panels. Based on control signals sent by the control module, the lamp panel selects the display signal path and the recording signal path, which are then multiplexed upstream to a smaller set of first shared data lines. Secondly, between the various lamp panels, a selection module gathers all the first shared data lines and, based on control signals sent by the control module, selectively connects the first shared data lines of the target lamp panel to the second shared data lines. Thus, the control module only needs to drive one set of second shared data lines to transmit data to any lamp panel in the display system.

[0033] As can be seen, the two-level sharing mechanism built into the display system through the technical solution provided in this application greatly reduces the number of signal lines within the display system. The control module only needs to provide a small number of input / output ports to connect to the second shared data line, each LED board, and the selection module to control multiple LED boards. This significantly reduces the need for input / output ports of the control module. Even for high-resolution, multi-LED display systems, only a small number of receiver cards are needed as control modules, thus improving the reliability of the display system.

[0050] In one aspect, a display system 10 is provided, which can be applied to a display device 600, and the display system 10 drives the display device 600 to display based on received image information.

[0051] In one embodiment, refer to Figure 1 The display system 10 includes:

[0052] Multiple light panels 100, each light panel 100 including a pixel unit matrix 110;

[0053] Multiple first shared data lines 200, and a light board 100 is connected to at least one first shared data line 200;

[0054] Multiple second shared data cables 300;

[0055] Select module 400, which is connected between the first shared data line 200 and the second shared data line 300;

[0056] The control module 500 is connected to the selection module 400, the light board 100, and the second shared data line 300;

[0057] The control module 500 is configured as follows:

[0058] Transmit display signals or recording signals via the second shared data line 300; and,

[0059] A control signal is sent to the selection module 400 and the target light board to control the selection module 400 to conduct the first shared data line 200 connected to the second shared data line 300 and the target light board, and to control the target light board to establish a display signal path 120 or a recording signal path 130 connected to its pixel unit matrix 110, so as to transmit the display signal to the target light board through the display signal path 120 or the recording signal to the target light board through the recording signal path 130.

[0060] Specifically, the display system 10 mainly includes a lamp board 100, a control module 500, and a selection module 400. The lamp board 100 and the selection module 400 are connected by multiple first shared data lines 200, and the selection module 400 and the control module 500 are connected by a second shared data line 300.

[0061] The light panel 100 includes multiple panels, each of which is connected to a corresponding set of first shared data lines 200. The light panel 100 receives data from the first shared data lines 200 to which it is connected and performs display or configuration based on the received data. When one or more light panels 100 are displaying or configuring, the light panel 100 currently displaying or configuring is the target light panel.

[0062] The data received by the lamp board 100 from the first shared data line 200 can be a display signal. When the lamp board 100 receives a display signal, it displays an image based on the display signal. The data received by the lamp board 100 from the first shared data line 200 can also be a recording signal. When the lamp board 100 receives a recording signal, it configures itself based on the recording signal.

[0063] The light panel 100 includes a pixel unit matrix 110 and a signal path. Specifically, the pixel unit matrix 110 includes multiple pixel units, which are arranged horizontally as pixel unit rows and vertically as pixel unit columns. The pixel unit rows and columns together form the pixel unit matrix 110. One end of the signal path is connected to the pixel unit matrix 110, specifically to a pixel unit row or column. The other end of the signal path converges into a first shared data line 200. The signal path includes a display signal path 120 and a recording signal path 130. The display signal path 120 is used to transmit display signals to the pixel unit matrix 110, and the recording signal path 130 is used to transmit recording signals to the pixel unit matrix 110.

[0064] One end of the selection module 400 is connected to multiple first shared data lines 200, and the other end is connected to a second shared data line 300. The selection module 400 is used to select a group of first shared data lines 200 connected to the target light board from the multiple first shared data lines 200, and connect the group of first shared data lines 200 to the second shared data lines 300, so that the data transmitted in the second shared data line 300 can flow to the currently selected group of first shared data lines 200, thereby enabling the data to be transmitted to the target light board.

[0065] The specific architecture of the selection module 400 is not unique. For example, the selection module 400 can be a multi-to-one switch or a selector. It only needs to be able to realize the selection and conduction function. Those skilled in the art can freely set it according to actual needs.

[0066] The control module 500 is connected to the second shared data line 300, and is also connected to the selection module 400 and the lamp board 100. The control module 500 is used to send display signals or recording signals via the second shared data line 300. As an example, the control module 500 can specifically be a receiving card in the display device 600, connected to a sending card in the display device 600. After generating the display signal or recording signal, the sending card sends the display signal or recording signal to the receiving card. The receiving card configures the display signal or recording signal accordingly, and then sends the display signal or recording signal via the second shared data line 300.

[0067] The control module 500 is also used to send control signals to the selection module 400 and the lamp board 100 to control the selection module 400 and the lamp board 100. When the control module 500 sends a control signal to the selection module 400, the selection module 400 responds to the control signal by selecting and connecting the second shared data line 300 to a set of first shared data lines 200 connected to the target lamp board indicated by the control signal, thereby enabling the display signal or recording signal sent by the control module 500 to be transmitted to the target lamp board. When the control module 500 sends a control signal to the lamp board 100, the lamp board 100 responds to the control signal by selecting the display signal path 120 or the recording signal path 130 within the lamp board 100, so that the display signal can be transmitted to the pixel unit matrix 110 through the display signal path 120 to drive the pixel unit matrix 110 for display, or so that the recording signal can be transmitted to the pixel unit matrix 110 through the recording signal path 130 to drive the pixel unit matrix 110 for configuration.

[0068] As an example, the control module 500 can generate and send corresponding control signals based on received display signals or recording signals. Taking the display signal as an example, the display signal contains the lamp board number of the target lamp board, which is used to indicate the target lamp board. At the same time, the control module 500 stores a mapping table of lamp board number and first shared data line number, which is used to indicate the first shared data line number of the group of first shared data lines 200 connected to the indicator board 100. When the control module 500 receives the display signal, it first determines the lamp board number corresponding to the target lamp board based on the display signal, then looks up the corresponding first shared data line number based on the lamp board number-first shared data line number mapping table, generates the control signal for the current display data according to the first shared data line number, and sends the control signal to the selection module 400 to connect the second shared data line 300 and the group of first shared data lines 200 indicated by the first shared data line number, and sends the control signal to the lamp board 100 indicated by the lamp board number according to the lamp board number, thereby establishing a display signal path 120 in the target lamp board.

[0069] When sending display signals, the control module 500 configures the timing of the display signals so that they are written to the pixel unit matrix 110 in a sequential order. For example, the control module 500 can configure the display signals to be written to the pixel unit matrix 110 sequentially by pixel unit row order. Similarly, when sending recording signals, the control module 500 configures the timing of the recording signals so that they are written to the pixel unit matrix 110 in a sequential order. For example, the control module 500 can configure the recording signals to be written to the pixel unit matrix 110 sequentially by pixel unit column order.

[0070] Based on the architecture of the display system 10 described above, the implementation principle of the display system 10 is described as follows:

[0071] When the control module 500 receives the display signal, it generates and sends a control signal based on the display signal. The control signal is sent to the selection module 400, activating the second shared data line 300 and the corresponding set of first shared data lines 200. The control signal is then sent to the target light panel, establishing a display signal path 120 from the control module 500 to the pixel unit matrix 110 within the target light panel. At this time, a data transmission path is established in the display system 10: control module 500 – second shared data line 300 – selection module 400 – first shared data line 200 – target light panel display signal path 120. The control module 500 transmits the display signal to the pixel unit matrix 110 of the target light panel through this data transmission path, enabling the pixel unit matrix 110 of the target light panel to display.

[0072] When the control module 500 receives the recording signal, it generates and sends a control signal based on the recording signal. The control signal is sent to the selection module 400, activating the second shared data line 300 and the corresponding set of first shared data lines 200. The control signal is then sent to the target LED panel, establishing a recording signal path 130 from the control module 500 to the pixel unit matrix 110 within the target LED panel. At this time, a data transmission path is established in the display system 10: control module 500 – second shared data line 300 – selection module 400 – first shared data line 200 – recording signal path 130 of the target LED panel. The control module 500 transmits the recording signal to the pixel unit matrix 110 of the target LED panel through this data transmission path, configuring the pixel unit matrix 110 within the target LED panel.

[0073] In the aforementioned display system 10, firstly, within the lamp panel 100, the transmission of display signals and the transmission of recording signals are separated. Based on the control signals sent by the control module 500, the lamp panel 100 selects the display signal path 120 and the recording signal path 130. The display signal path 120 and the recording signal path 130 are multiplexed upstream to a smaller set of first shared data lines 200. Secondly, among the various lamp panels 100, the selection module 400 gathers all the first shared data lines 200 and, based on the control signals sent by the control module 500, selectively connects the first shared data lines 200 of the target lamp panel to the second shared data lines 300. Thus, the control module 500 only needs to drive one set of second shared data lines 300 to transmit data to any lamp panel 100 in the display system 10.

[0074] As can be seen, the two-level sharing mechanism built into the display system 10 through the technical solution provided in this application greatly reduces the number of signal lines within the display system 10. The control module 500 only needs to provide a small number of input / output ports to connect with the second shared data line 300, each lamp board 100, and the selection module 400 to control multiple lamp boards 100. This significantly reduces the requirement for input / output ports of the control module 500. Even for a high-resolution display system 10 with multiple lamp boards 100, only a small number of receiver cards are needed as the control module 500, thereby improving the reliability of the display system 10.

[0075] In one embodiment, the light panel 100 includes an integration unit 140, wherein:

[0076] The first end of the integration unit 140 is connected to the pixel unit matrix 110, the second end of the integration unit 140 is connected to the first shared data line 200, and the control end of the integration unit 140 is connected to the control module 500.

[0077] The integration unit 140 is used to connect the first shared data line 200 to the display signal path 120 or the first shared data line 200 to the recording signal path 130 according to the control signal sent by the control module 500.

[0078] Specifically, refer to Figure 2 The first end of the integration unit 140 is connected to the pixel unit matrix 110, and the signal line between the first end and the pixel unit matrix 110 forms the display signal path 120 and the recording signal path 130. The second end of the integration unit 140 is connected to the first shared data line 200, and the second end is specifically connected to a set of first shared data lines 200 corresponding to the current lamp board 100, so that the integration unit 140 can receive display signals or recording signals from the first shared data line 200. The control end of the integration unit 140 is connected to the control module 500.

[0079] The integration unit 140 receives control signals sent by the control module 500 at its control terminal, and selectively activates the display signal path 120 or the recording signal path 130 based on the indication of the control signals. When the control module 500 is ready to transmit a display signal, it sends a control signal to the integration unit 140 of the target lamp board, instructing the integration unit 140 to activate a set of first shared data lines 200 connected to the target lamp board and the display signal path 120, so that the pixel unit matrix 110 in the target lamp board receives the display signal through the display signal path 120 and performs display; when the control module 500 is ready to transmit a recording signal, it sends a control signal to the integration unit 140 of the target lamp board, instructing the integration unit 140 to activate a set of first shared data lines 200 connected to the target lamp board and the recording signal path 130, so that the pixel unit matrix 110 in the target lamp board receives the recording signal through the recording signal path 130 and performs configuration.

[0080] like Figure 2 As shown, based on the integrated unit 140, the display signal and the recording signal share a first shared data line 200 at the second end of the integrated unit 140. It can be understood that the integrated unit 140 can be considered as converging the display signal path 120 and the recording signal path 130 into a single first shared data line 200. In the above embodiment, based on distinguishing between the display signal path 120 and the recording signal path 130, the integrated unit 140 converges the display signal path 120 and the recording signal path 130 into a smaller set of first shared data lines 200. The control module 500 enables the integrated unit 140 to select between the display signal path 120 and the recording signal path 130. Through the technical solution provided in the above embodiment, the number of outgoing lines on the lamp board 100 is significantly reduced.

[0081] In one embodiment, the pixel unit matrix 110 includes multiple display data lines and multiple recording data lines, the display signal path 120 consists of at least one display data line, and the recording signal path 130 consists of at least one recording data line.

[0082] Specifically, the pixel unit matrix 110 includes multiple display data lines and multiple recording data lines, which are connected to the pixel units. The display signal path 120 consists of at least one display data line, and the recording signal path 130 consists of at least one recording data line.

[0083] The display data lines can be row data lines or column data lines, and the recording data lines can also be row data lines or column data lines. Multiple row data lines are evenly arranged parallel to the row direction of the pixel units in the pixel unit matrix 110, and multiple column data lines are evenly arranged parallel to the column direction of the pixel units in the pixel unit matrix 110. The row data lines and column data lines intersect each other and are connected to the pixel units at their intersection points.

[0084] In one feasible embodiment, both the display data line and the recording data line are composed of row data lines in the pixel unit matrix 110, or both the display data line and the recording data line are composed of column data lines in the pixel unit matrix 110. The specific configuration can be seen in the following example.

[0085] As an example, a portion of the row data lines in the pixel unit matrix 110 serve as display data lines, forming a display signal path 120, which is used to transmit display signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200; another portion of the row data lines in the pixel unit matrix 110 serve as recording data lines, forming a recording signal path 130, which is used to transmit recording signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200.

[0086] As an example, a portion of the column data lines in the pixel unit matrix 110 serve as display data lines, forming a display signal path 120, which is used to transmit display signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200; another portion of the column data lines in the pixel unit matrix 110 serve as recording data lines, forming a recording signal path 130, which is used to transmit recording signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200.

[0087] In the above example, both the recording signal and the display signal are transmitted via row data lines, or both the recording signal and the display signal are transmitted via column data lines, thus isolating the two signal transmission paths and providing an implementation basis for the pixel unit matrix 110 to converge the output lines into a smaller group of first shared data lines 200.

[0088] In another feasible embodiment, the display data lines consist of either row data lines or column data lines in the pixel unit matrix 110, and the recording data lines consist of either row data lines or column data lines in the pixel unit matrix 110. The specific configuration can be seen in the following example.

[0089] As an example, all row data lines in the pixel unit matrix 110 serve as display data lines, forming a display signal path 120, which is used to transmit display signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200; all column data lines in the pixel unit matrix 110 serve as recording data lines, forming a recording signal path 130, which is used to transmit recording signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200.

[0090] As an example, all row data lines in the pixel unit matrix 110 serve as recording data lines, forming a recording signal path 130, which transmits recording signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200; all column data lines in the pixel unit matrix 110 serve as display signal paths 120, which transmit display signals to the pixel unit matrix 110 when connected to a corresponding set of first shared data lines 200.

[0091] In the above example, one of the display signal or the recording signal is transmitted by the row data line, and the other of the display signal or the recording signal is transmitted by the column data line. On the basis of isolating the two signal transmission paths, the original data lines in the pixel unit matrix 110 are effectively utilized, and the overall system integration is increased.

[0092] In one embodiment, the control signal includes a first control signal, and the integration unit 140 includes a first signal transceiver 141 and a second signal transceiver 142, wherein:

[0093] The first transceiver 141 includes multiple first terminals, multiple second terminals, and a control terminal. Each first terminal of the first transceiver 141 is connected to each display data line in a pixel unit matrix 110. Each second terminal of the first transceiver 141 is connected to each first shared data line 200. The control terminal of the first transceiver 141 is connected to the control module 500. The first transceiver 141 is used to turn on the first terminals and the second terminals of the first transceiver 141 when a first control signal is received.

[0094] The second transceiver 142 includes multiple first terminals, multiple second terminals, and a control terminal. Each first terminal of the second transceiver 142 is connected to each recording data line in a pixel unit matrix 110. Each second terminal of the second transceiver 142 is connected to each first shared data line 200. The control terminal of the second transceiver 142 is connected to the control module 500. The second transceiver 142 is used to turn on the first and second terminals of the first transceiver 141 when it receives a first control signal.

[0095] Specifically, refer to Figure 3 or Figure 4 The integration unit 140 includes a first signal transceiver 141 and a second signal transceiver 142. Each first terminal of the first signal transceiver 141 is connected to each display data line in a pixel unit matrix 110, and each first terminal of the second signal transceiver 142 is connected to each recording data line in a pixel unit matrix 110. Both the first signal transceiver 141 and the second signal transceiver 142 are controlled by the control module 500.

[0096] The control module 500 controls the selective conduction state of the integration unit 140 by sending a first control signal to either the first transceiver 141 or the second transceiver 142. Specifically, both the first transceiver 141 and the second transceiver 142 are in a turned-off state when they do not receive the first control signal. When the control module 500 sends the first control signal to the first transceiver 141, the first transceiver 141 conducts its first and second terminals, enabling a set of first shared data lines 200 to conduct with each display data line; when the control module 500 sends the first control signal to the second transceiver 142, the second transceiver 142 conducts its first and second terminals, enabling a set of first shared data lines 200 to conduct with each recording data line.

[0097] Since the first control signal only needs to control the port switching state of the first transceiver 141 or the second transceiver 142, or in other words, the first control signal only needs to control whether the first transceiver 141 or the second transceiver 142 is working, the first control signal can be an enable signal. Furthermore, because the control module 500 needs to control multiple first transceivers 141 and multiple second transceivers 142, there are multiple first control signals, the number of which is the sum of the number of first transceivers 141 and the number of second transceivers 142.

[0098] As an example, both the first signal transceiver 141 and the second signal transceiver 142 can be 74HC245 eight-channel tri-state output bidirectional transceivers.

[0099] As an example, continue to refer to Figure 3 or Figure 4 The lamp panel #1 in the display system 10 includes a pixel unit matrix 110 with M rows and N columns. This pixel unit matrix 110 includes M display data lines and N recording data lines. The M display data lines are respectively connected to the M first terminals of the first signal transceiver 141, and the N recording data lines are respectively connected to the N first terminals of the second signal transceiver 142. Multiple second terminals of the first signal transceiver 141 are respectively connected to a set of first shared data lines 200 corresponding to the lamp panel #1. Simultaneously, multiple second terminals of the second signal transceiver 142 are also respectively connected to a set of first shared data lines 200 corresponding to the lamp panel #1. M and N are both integers greater than 0.

[0100] In this example, when the control module 500 sends a display signal to a set of first shared data lines 200 corresponding to lamp board #1, it simultaneously controls the first transceiver 141 to operate, enabling the set of first shared data lines 200 corresponding to lamp board #1 to conduct with M display data lines. The display signal is then sequentially written into the pixel unit matrix 110 through the M display data lines. When the control module 500 sends a recording signal to a set of first shared data lines 200 corresponding to lamp board #1, it simultaneously controls the second transceiver 142 to operate, enabling the set of first shared data lines 200 corresponding to lamp board #1 to conduct with N recording data lines. The recording signal is then sequentially written into the pixel unit matrix 110 through the N recording data lines. It can be seen that the display signal and the recording signal reuse the set of first shared data lines 200 corresponding to lamp board #1 at different times. To ensure data integrity during the transmission of display and recording signals, the number of the set of first shared data lines 200 corresponding to lamp board #1 is no less than the larger of M and N.

[0101] In the above embodiment, the first transceiver 141 controls whether the display data line can transmit data at the current moment, and the second transceiver 142 controls whether the recording data line can transmit data at the current moment. The continuity of the display signal path 120 and the recording signal path 130 can be controlled by controlling the operating states of the first transceiver 141 and the second transceiver 142, resulting in simple control logic.

[0102] In one embodiment, the control signal includes a second control signal, and the selection module 400 includes a plurality of third signal transceivers 410, the number of which is equal to the number of lamp panels 100, wherein:

[0103] Each third transceiver 410 corresponds one-to-one with each lamp board 100. The first end of the third transceiver 410 is connected to the first shared data line 200 connected to its corresponding lamp board 100, the second end of the third transceiver 410 is connected to the second shared data line 300, and the control end of the third transceiver 410 is connected to the control module 500. The third transceiver 410 is used to conduct its first end and second end when it receives a second control signal, so as to conduct the second shared data line 300 to the first shared data line 200 connected to the target lamp board.

[0104] Specifically, refer to Figure 3 The selection module 400 includes a plurality of third signal transceivers 410. The number of third signal transceivers 410 is consistent with the number of lamp panels 100 in the display signal. Each lamp panel 100 in the display system 10 corresponds to one third signal transceiver 410.

[0105] The control module 500 controls the selection and conduction status of the selection module 400 by sending a second control signal to the third transceiver 410. Specifically, the third transceiver 410 is in an off state when it does not receive the second control signal, and the selection module 400 does not connect the second shared data line 300 to a set of first shared data lines 200 connected to any lamp board 100. When the control module 500 sends the second control signal to a third transceiver 410, the third transceiver 410 conducts its first and second terminals, making the second shared data line 300 connected to a set of first shared data lines 200. At this time, the data sent by the control module 500 can be transmitted to the set of first shared data lines 200 connected to the lamp board 100 corresponding to the third transceiver 410.

[0106] Since the second control signal only needs to control the on / off state of the port of the third transceiver 410, or in other words, the second control signal only needs to control whether the third transceiver 410 works, the second control signal can be an enable signal. Furthermore, since the control module 500 needs to control multiple third transceivers 410, there are multiple second control signals, the number of which is the same as the number of third transceivers 410.

[0107] As an example, the third signal transceiver 410 could be a 74HC245 eight-channel tri-state output bidirectional transceiver.

[0108] As an example, continue to refer to Figure 3 In the display system 10, lamp panel #1 includes a pixel unit matrix 110 with M rows and N columns, and lamp panel #2 includes a pixel unit matrix 110 with I rows and J columns. M, N, I, and J are all integers greater than 0, and there exists M > N > I > J. At this time, lamp panel #1 corresponds to a set of M first shared data lines 200, and lamp panel #2 corresponds to a set of I first shared data lines 200.

[0109] In this example, the first end of the third transceiver 410 corresponding to lamp board #1 is connected to a set of M first shared data lines 200, the first end of the third transceiver 410 corresponding to lamp board #2 is connected to a set of I first shared data lines 200, the multiple second ends of the third transceiver 410 corresponding to lamp board #1 are respectively connected to multiple second shared data lines 300, and at the same time, the multiple second ends of the third transceiver 410 corresponding to lamp board #2 are also respectively connected to multiple second shared data lines 300.

[0110] When control module 500 transmits data to lamp board #1, it synchronously controls the third transceiver 410 corresponding to lamp board #1 to operate, making the M first shared data lines 200 and the second shared data lines 300 connected to lamp board #1 conductive, and the data is sequentially written to lamp board #1 through the M first shared data lines 200. When control module 500 transmits data to lamp board #2, it synchronously controls the third transceiver 410 corresponding to lamp board #2 to operate, making the I first shared data lines 200 and the second shared data lines 300 connected to lamp board #2 conductive, and the data is sequentially written to lamp board #2 through the I first shared data lines 200. As can be seen, the data sent by the control module 500 is reused on the second shared data line 300 at different times. In order to ensure the integrity of the data sent to different light boards 100, the number of the second shared data lines 300 is not less than the larger of M and I. To extend to more light boards 100, the number of the second shared data lines 300 is not less than the larger of the number of display data lines and the number of recording data lines in the pixel unit matrix 110 of all light boards 100.

[0111] In the above embodiment, the third transceiver 410 selects to transmit the data sent by the control module 500 to any one of the lamp boards 100. The third transceiver 410 converges multiple first shared data lines 200, allowing the data sent by the control module 500 to be multiplexed on the second shared data line 300. The control module 500 only needs to control the working state of each third transceiver 410 to transmit the data to the target lamp board. Through the above embodiment, the number of signal lines in the display system 10 is effectively reduced while simplifying the control logic, which is beneficial to ensuring the reliability of the display system 10.

[0112] In one embodiment, the control signal includes a second control signal, and the selection module 400 includes a multiplexer, wherein:

[0113] The multiplexer includes multiple input channels, multiple output channels, and a control terminal. Each output channel of the multiplexer is connected to a first shared data line 200 connected to different lamp boards 100. Each input channel of the multiplexer is connected to a second shared data line 300. The control terminal of the multiplexer is connected to a control module 500. The multiplexer is used to connect its input channels and the output channels indicated by the second control signal according to the second control signal, so as to connect the second shared data line 300 to the first shared data line 200 connected to the target lamp board.

[0114] Specifically, refer to Figure 4The selection module 400 includes a multiplexer 420 with multiple output channels divided into different groups. Each group of output channels corresponds to a lamp board 100 in the display system 10 and is connected to a group of first shared data lines 200 connected to the lamp board 100. The multiplexer 420 also includes multiple input channels, each connected to multiple second shared data lines 300. The control terminal of the multiplexer 420 is connected to the control module 500.

[0115] The control module 500 controls the selection and conduction status of the selection module 400 by sending a second control signal to the multiplexer. Specifically, when the multiplexer does not receive the second control signal, it is in an off state, and its input channel and any set of output channels are not connected. At this time, the selection module 400 does not connect the second shared data line 300 to the set of first shared data lines 200 connected to any lamp board 100. When the control module 500 sends the second control signal to the multiplexer, the multiplexer connects its input channel and the set of output channels indicated by the second control signal, so that the second shared data line 300 is connected to the set of first shared data lines 200 corresponding to the currently indicated output channel.

[0116] Since the second control signal needs to control the conduction status of different output channels of the multiplexer and indicate the currently selected output channel, the second control signal is a logic signal, which can be a multi-bit binary signal. Therefore, there is only one second control signal.

[0117] As an example, a multiplexer could be the 74HC4051 eight-channel analog multiplexer.

[0118] As an example, continue to refer to Figure 3 In the display system 10, lamp panel #1 includes a pixel unit matrix 110 with M rows and N columns, and lamp panel #2 includes a pixel unit matrix 110 with I rows and J columns. M, N, I, and J are all integers greater than 0, and there exists M > N > I > J. At this time, lamp panel #1 corresponds to a set of M first shared data lines 200, and lamp panel #2 corresponds to a set of I first shared data lines 200.

[0119] In this example, the M first shared data lines 200 connected to lamp board #1 are connected to a set of output channels of the multiplexer, for example, sequentially connected to output channels A1~Am. The I first shared data lines 200 connected to lamp board #2 are connected to a set of output channels of the multiplexer, for example, sequentially connected to output channels B1~Bi. The input channels of the multiplexer are connected to multiple second shared data lines 300 respectively. i and m are both integers greater than 0.

[0120] When the control module 500 transmits data to lamp board #1, it controls the input and output channels A1~Am of the multiplexer to be connected, so that the M first shared data lines 200 and the second shared data lines 300 connected to lamp board #1 are connected, and the data is sequentially written to lamp board #1 through the M first shared data lines 200. When the control module 500 transmits data to lamp board #2, it controls the input and output channels B1~Bi of the multiplexer to be connected, so that the I first shared data lines 200 and the second shared data lines 300 connected to lamp board #2 are connected, and the data is sequentially written to lamp board #2 through the I first shared data lines 200. As can be seen, the data sent by the control module 500 is reused on the second shared data line 300 at different times. In order to ensure the integrity of the data sent to different light boards 100, the number of the second shared data lines 300 is not less than the larger of M and I. To extend to more light boards 100, the number of the second shared data lines 300 is not less than the larger of the number of display data lines and the number of recording data lines in the pixel unit matrix 110 of all light boards 100.

[0121] In this embodiment, compared to the aforementioned embodiment where the selection module 400 includes multiple third transceivers 410, only a single second control signal is needed to control the selection module 400. This results in fewer lines in the display system 10 and fewer ports in the control module 500, further improving the reliability of the display system 10.

[0122] In one embodiment, the number of first shared data lines 200 connected to an integration unit 140 is equal to the greater of the number of display data lines and the number of recording data lines connected to the integration unit 140.

[0123] Specifically, for an integration unit 140, the display data lines and recording data lines are converged into a first shared data line 200. Since the display signal needs to be written to the pixel unit matrix 110 line by line through the display data lines, and the recording signal needs to be written to the pixel unit matrix 110 column by column through the recording data lines, and the display signal and the recording signal reuse the first shared data line 200, in order to ensure data integrity, the number of first shared data lines 200 connected to an integration unit 140 needs to be greater than the larger of the number of display data lines and the number of recording data lines connected to the integration unit 140.

[0124] Furthermore, to minimize the number of lines in the display system 10, the number of first shared data lines 200 connected to an integration unit 140 is equal to the greater of the number of display data lines connected to the integration unit 140 and the number of recording data lines. For example... Figure 3 or Figure 4As shown, for lamp board #1, it has a pixel unit matrix 110 with M rows and N columns, and correspondingly, it has M display data lines and N recording data lines. If M > N, then the integration unit 140 of the lamp board 100 is connected to the M first shared data lines 200.

[0125] This embodiment ensures that the display signal and the recording signal can be completely transmitted to the pixel unit matrix 110, while minimizing the number of lines in the display system 10, thus ensuring the reliability of the display system 10 and reducing its production cost.

[0126] In one embodiment, the number of second shared data lines 300 is equal to the maximum of the number of display data lines and the number of recording data lines in each pixel unit matrix 110.

[0127] Specifically, the selection module 400 aggregates multiple sets of first shared data lines 200 into a second shared data line 300. When the display system 10 includes multiple lamp panels 100, it is necessary to ensure the integrity of the data transmitted to at least the lamp panel 100 with the highest resolution (i.e., the most pixel units). Therefore, to ensure data integrity, the number of second shared data lines 300 needs to be greater than the larger of the number of display data lines and the number of recording data lines in each pixel unit matrix 110.

[0128] Furthermore, to minimize the number of lines in the display system 10, the number of second shared data lines 300 needs to be equal to the greater of the number of display data lines and the number of recording data lines in each pixel unit matrix 110. For example... Figure 3 or Figure 4 As shown, for lamp board #1, it has a pixel unit matrix 110 with M rows and N columns, corresponding to M display data lines and N recording data lines. If M > N, then lamp board #1 is connected by M first shared data lines 200. For lamp board #2, it has a pixel unit matrix 110 with I rows and J columns, corresponding to I display data lines and J recording data lines. If M > N > I > J, then lamp board #2 is connected by I first shared data lines 200. For lamp boards #3 to #k, assuming that the number of display data lines and the number of recording data lines for lamp boards #3 to #k are all less than or equal to M, then the current display system 10 only needs M second shared data lines 300 to meet the data transmission requirements.

[0129] Through this embodiment, while ensuring the integrity of the data transmitted to the lamp panel 100 with the highest resolution (i.e., the most pixel units), the number of lines in the display system 10 is reduced as much as possible, thus ensuring the reliability of the display system 10 while reducing the production cost of the display system 10.

[0130] In one embodiment, the control module 500 is further configured as follows:

[0131] When the target light board establishes the display signal path 120, the target light board disconnects the recording signal path 130; and when the target light board establishes the recording signal path 130, the target light board disconnects the display signal path 120.

[0132] Figure 5 This is a schematic diagram of the control timing logic of the display system 10 in one embodiment, which is used to control the timing logic of the system. Figure 3 The display system 10 shown is controlled. Combined with... Figure 3 and Figure 5 Based on the above embodiments, taking the current control light panel #1 for display as an example, this application will be further described.

[0133] The control module 500 receives a display signal indicating that the current requirement is to control lamp board #1 to display. Based on the display signal, the control module 500 generates a first control signal and a second control signal. The control module 500 sends the second control signal to the third transceiver 410 corresponding to lamp board #1. The third transceiver 410 corresponding to lamp board #1 is enabled, and its two ends are connected. At this time, the third transceivers 410 corresponding to other lamp boards 100 are disabled, and their two ends are not connected. The control module 500 sends the first control signal to the first transceiver 141 in the integration unit 140 of lamp board #1. The first transceiver 141 in the integration unit 140 of lamp board #1... When transceiver 141 is enabled, the second transceiver 142 in the integration unit 140 of lamp board #1 is disabled. The display signal path 120 of lamp board #1 is established while the recording signal path 130 is turned off. Lamp board #1 is in a working state where the display mode is active and the recording mode is inactive. The control module 500 configures the timing of the display signal transmission. The display signal is transmitted sequentially through the second shared data line 300, the third transceiver 410 corresponding to lamp board #1 in the selection module 400, the first shared data line 200, the first transceiver 141 in the integration unit 140 of lamp board #1, and the display data line to the pixel unit matrix 110 of lamp board #1. The signal is written line by line into the pixel unit matrix 110 of lamp board #1, and lamp board #1 displays the signal.

[0134] Figure 6 This is a schematic diagram of the control timing logic of the display system 10 in another embodiment, which is used for... Figure 4 The display system 10 shown is controlled. Combined with... Figure 4 and Figure 6 Based on the above embodiments, this application will be further described using the current control light board #2 as an example for recording.

[0135] The control module 500 receives a recording signal, which indicates that the current control panel #2 needs to be configured with an address. Based on the recording signal, the control module 500 generates a first control signal and a second control signal. The control module 500 sends the second control signal to a multiplexer. The input channel of the multiplexer is connected to the output channel connected to a set of first shared data lines 200 corresponding to the lamp panel #2, but the input channel of the multiplexer is not connected to other output channels. The control module 500 sends the first control signal to the second transceiver 142 in the integration unit 140 of the lamp panel #2. The second transceiver 142 in the integration unit 140 of the lamp panel #2 is enabled. When the first signal transceiver 141 in the integration unit 140 of the lamp board #2 is disabled, the recording signal path 130 of the lamp board #2 is established while the display signal path 120 is turned off, the lamp board #2 is in a working state where the display mode is activated and the recording mode is not activated; the control module 500 configures the transmission timing of the recording signal, and the recording signal is transmitted to the pixel unit matrix 110 of the lamp board #2 in sequence through the second shared data line 300, the multiplexer, the first shared data line 200, the second signal transceiver 142 in the integration unit 140 of the lamp board #2, and the recording data line, and is written to the pixel unit matrix 110 of the lamp board #2 column by column in sequence, and the lamp board #2 is configured with an address.

[0136] In another respect, refer to Figure 7 A display device 600 is provided, which includes a housing 610 and a display system 10 as described in any of the embodiments of the above aspects.

Other parts of the display system 10 can be disposed inside the housing 610 of the display device 600, driving each lamp panel 100 to display. As an example, the display device 600 can be an EL (Electroluminescent) display device, an EEFL (External Electrode Fluorescent Lamp) display device 600, an LED display device, etc.
