[0031] For details, please refer to Figures 1 to 5 The embodiment of the present application provides a display structure including a mainboard 10 and a display unit 30. The mainboard 10 has a first signal conversion module 140 and a fixed frequency module 150. The first signal conversion module 140 is used to convert a video signal in an input signal into a first signal, and the fixed frequency module 150 is used to fix the output frequency of the first signal. The display unit 30 is electrically connected to the mainboard 10 and has a third signal conversion module 320 and a display module 330. The third signal conversion module 320 is used to convert the first signal into a third signal. The display module 330 is electrically connected to the third signal conversion module 320 and is used to receive the third signal to display an image.

[0032] like Figure 1 As shown, in some embodiments, the first signal conversion module 140 on the mainboard 10 can convert video signals in different types of input signals into first signals to improve the compatibility of the display device so that it can meet the display requirements of various multimedia devices. The fixed frequency module 150 on the mainboard 10 is used to fix the output frequency of the first signal to ensure the consistency of the output frequency to prevent screen flickering and other phenomena during the display process. The third signal conversion module 320 of the display unit 30 is used to convert the first signal into a third signal to meet the display requirements of the display module 330 and realize screen display.

[0033] This display structure is particularly suitable for display devices, such as large-screen direct-view televisions. Correspondingly, the motherboard 10 can be a TV motherboard. The TV motherboard has a smart TV's SOC (System on Chip), such as an MTK model SOC.

[0034] The first signal conversion module 140 on the motherboard 10 is used to convert the video signal in the external input signal into a first signal. The first signal can be a V-by-One signal, thereby meeting the communication protocol requirements of most display devices and adapting to various models of display devices. Specifically, based on different types of input signals, the first signal conversion module 140 can convert the video signal into a V-by-One signal to ensure the compatibility of the display devices.

[0035] The frequency-fixing module 150 on the motherboard 10 is used to fix the output frequency of the first signal. This makes the output frequency value of the first signal output to the display unit 30 relatively fixed, so as to prevent the display unit 30 from flickering.

[0036] Display unit 30 can be a large-size display screen, such as a miniLED (light-emitting diode) ultra-large screen direct-view TV. The third signal conversion module 320 in display unit 30 is used to convert the input signal into a TTL digital signal, which enables the miniLED to perform video display based on the TTL digital signal.

[0037] like Figure 3 As shown, in some embodiments, the motherboard 10 further includes a first signal receiving module 120 and a first signal transmitting module 170. The first signal is a V-by-One signal. The first signal receiving module 120 is configured to receive the input signal. The first signal conversion module 140 is electrically connected to the first signal receiving module 120 and is used to convert the video signal in the input signal into a V-by-One signal. The first signal transmitting module 170 is electrically connected to the first signal conversion module 140 and is used to transmit the V-by-One signal. The frequency fixing module 150 is electrically connected to the first signal transmitting module 170 and is used to fix the output frequency of the V-by-One signal to a preset value.

[0038] Understandably, the first signal receiving module 120 is used to receive input signals from the outside. The video signal in the input signal is sent to the first signal conversion module 140 through the first signal receiving module 120, thereby converting it into a V-by-One signal. The first signal sending module 170 is used to send the frequency-fixed V-by-One signal to the display unit 30.

[0039] The first signal receiving module 120 can be a signal receiver, which is integrated on the motherboard 10 and is used to receive input signals. The first signal transmitting module 170 can be a signal transmitter, which is integrated on the motherboard 10 and is used to output V-by-One signals.

[0040] The use of V-by-One signaling allows for high-speed signal transmission, supporting a maximum speed of 3.75Gbps (1Gbps represents a transmission rate of 1000 megabits per second), thus meeting the high-speed data transmission requirements of large-size LCD displays. Furthermore, it supports data transmission rates up to 8Gbps, satisfying the needs of high-definition video transmission.

[0041] Using V-by-One signals can also solve the time delay problem of wiring in traditional transmission schemes and improve signal synchronization based on its own clock signal recovery technology.

[0042] Using V-by-One signals also allows for support of multiple resolutions based on their own protocol. For example, it can support common resolutions such as 4K, 1080p, 720p, and 480p.

[0043] Using V-by-One signals also allows the protocol itself to support multiple color depths. For example, it can support multiple color depths such as RGB 8 / 10-bit and YCbCr 8 / 10-bit.

[0044] Please continue to refer to Figure 3 In some embodiments, the motherboard 10 further includes a frequency compensation module 160, which is electrically connected to the fixed-frequency module 150. For V-by-One signals with an output frequency less than a preset value, the frequency compensation module 160 compensates the output frequency of the V-by-One signal to the preset value. For V-by-One signals with an output frequency greater than the preset value, the frequency compensation module 160 compensates the output frequency of the V-by-One signal to n times the preset value, where n is a natural number and n≥2. For example, n=2,3,4,5…….

[0045] Understandably, the frequency compensation module 160 on the motherboard 10 performs frequency compensation for the V-by-One signal. When the output frequency of the V-by-One signal is less than a preset value, the output frequency compensation value of the V-by-One signal is set to the preset value to ensure that subsequent displays do not flicker. When the output frequency of the V-by-One signal is greater than the preset value, the output frequency compensation value of the V-by-One signal is set to n times the preset value. Since the output frequency is an integer multiple of the preset value, this also ensures that subsequent displays do not flicker.

[0046] For example, if the preset value is set to 60 Hz, 60 frames of images need to be output every second. When the output frequency of the V-by-One signal is 50 Hz, the frequency compensation module 160 compensates the output frequency of the V-by-One signal to 60 Hz. When the output frequency of the V-by-One signal is 80 Hz, the frequency compensation module 160 compensates the output frequency of the V-by-One signal to 120 Hz.

[0047] Specifically, when the output frequency of a V-by-One signal is 50 Hz, only 50 frames can be output per second. In this case, one of the two adjacent frames is copied every five frames. That is, one frame is copied and inserted every five frames. Ultimately, the output frequency of the V-by-One signal is compensated to 60 Hz, thus meeting output requirements and preventing screen flickering.

[0048] It can be seen that the frequency compensation module 160 can be a frame duplicator that performs corresponding frame duplication on the V-by-One signal based on the frequency compensation of the corresponding value, so that the output frequency of the V-by-One signal reaches a preset value or n times the preset value.

[0049] Understandably, the motherboard 10 integrates a comparator module, which can compare the output frequency of the V-by-One signal with a preset value.

[0050] If the output frequency of the V-by-One signal is equal to the preset value or n times the preset value, the comparison module outputs a pass signal, so that the mainboard 10 controls the V-by-One signal to be output directly without frequency compensation through the frequency compensation module 160.

[0051] If the output frequency of the V-by-One signal is less than the preset value, the comparison module outputs a first compensation signal, causing the mainboard 10 to control the frequency compensation module 160 to perform frequency compensation on the V-by-One signal so that the output frequency of the V-by-One signal is compensated to the preset value.

[0052] If the output frequency of the V-by-One signal is greater than the preset value, the comparison module outputs a second compensation signal, causing the motherboard 10 to control the frequency compensation module 160 to perform frequency compensation on the V-by-One signal, so that the output frequency of the V-by-One signal is compensated to n times the preset value.

[0053] The comparison module is a comparator that only needs to perform size comparisons and provide feedback based on the comparison results.

[0054] In some embodiments, the preset value is between 24 Hz and 60 Hz. For example, the preset value is 24 Hz, 30 Hz, 50 Hz, or 60 Hz. The preset value can be set based on the specific signal of the display device. This application embodiment does not limit the specific size of the preset value.

[0055] Please continue to refer to Figure 3 In some embodiments, the motherboard 10 is also provided with an external module 110, which is electrically connected to the first signal receiving module 120 and is configured to connect to an external input device.

[0056] Understandably, the external module 110 is used for signal connection to an external input device. The external module 110 can be a connector mounted on the housing of the actual device, which is electrically connected to the motherboard 10. The connector is used to plug in an external input device, thereby establishing an electrical connection between the external input device and the motherboard 10.

[0057] In some embodiments, the external module 110 includes one or more of the following: a closed-circuit television access module, a WiFi access module, a USB access module, an analog signal access module, a set-top box access module, and a game console access module.

[0058] Based on the selection of the external module 110, the display device can be adapted to mainstream multimedia display functions. Specifically, the closed-circuit television signal can be accessed through the closed-circuit television access module to achieve image display. The WiFi access module can receive WiFi signals to achieve image display. The USB access module can be inserted into the USU connector to achieve image display. The analog signal access module can receive AV signals (Audio-Video, audio and video signals) to achieve image display. The set-top box access module can receive set-top box signals to achieve image display. The game console access module can be used to access game console signals to achieve image display.

[0059] This enables display devices to be compatible with the vast majority of multimedia devices, improving their compatibility and applicability.

[0060] Understandably, based on different types of input signals, the first signal conversion module 140 on the motherboard 10 can convert the video signal in the input signal into a V-by-One signal to meet display requirements.

[0061] like Figure 3As shown, in some embodiments, the motherboard 10 is also provided with a signal splitting module 130, which is electrically connected to the first signal receiving module 120 and is used to receive the input signal and split the input signal into an audio signal and a video signal. The first signal conversion module 140 is electrically connected to the signal splitting module 130 and is used to receive the video signal. The signal splitting module 130 is also electrically connected to the audio device 40 and is used to send the audio signal to the audio device 40.

[0062] It is understandable that the input signal from an external input device includes not only video signals but also audio signals. To ensure voice playback functionality, a splitting module is integrated on the motherboard 10 to separate the video and audio signals in the input signal. The splitting module transmits the video signal to the first signal receiving module 120, which then sends the video signal to the first signal conversion module 140 for further processing. The splitting module directly transmits the audio signal to the audio device 40 for audio playback.

[0063] The audio device 40 can be a speaker, amplifier, or other device integrated into the display device. Alternatively, the audio device 40 can be a separate speaker or other device independent of the display device.

[0064] In some embodiments, the segmentation module can be configured as different pins. Based on the pins corresponding to the audio signal and the video signal in the signal transmission, the pin of the video signal is electrically connected to the first signal receiving module 120, and the pin of the audio signal is electrically connected to the audio device 40.

[0065] In some embodiments, the splitting module can be a one-input, multiple-output signal splitter. The signal splitter distinguishes between video and audio signals in the input signal. The video signal is output from the first interface of the signal splitter, and the first interface is electrically connected to the first signal receiving module 120, thereby enabling the video signal to be sent to the first signal receiving module 120. The audio signal is output from the second interface of the signal splitter, and the second interface is electrically connected to the audio device 40, thereby enabling the audio signal to be sent to the audio device 40.

[0066] like Figure 2 and Figure 4As shown, in some embodiments, the display structure further includes an adapter board 20. The adapter board 20 is electrically connected to the motherboard 10. The adapter board 20 has a second signal receiving module 210, a second signal conversion module 220, and a second signal transmitting module 230. The second signal receiving module 210 is electrically connected to the first signal transmitting module 170 and is used to receive V-by-One signals. The second signal conversion module 220 is electrically connected to the second signal receiving module 210 and is used to convert V-by-One signals into HDMI signals. The second signal transmitting module 230 is electrically connected to both the second signal conversion module 220 and the third signal conversion module 320, and is used to receive HDMI signals from the second signal conversion module 220 and send the received HDMI signals to the third signal conversion module 320. The third signal conversion module 320 is used to convert the HDMI signals into a third signal.

[0067] Understandably, by setting up an adapter board 20, and configuring a second signal receiving module 210, a second signal conversion module 220, and a second signal transmitting module 230 on the adapter board 20, the V-by-One signal transmitted from the motherboard 10 to the adapter board 20 can be converted into an HDMI signal by the signal conversion module 220. Then, the second signal transmitting module 230 sends the HDMI signal to the third signal conversion module 320. After the third signal conversion module 320 converts the HDMI signal into a third signal, the image can be displayed on the display unit 30.

[0068] The second signal receiving module 210 is a signal receiver, the second signal sending module 230 is a signal transmitter, and the second signal converting module 220 is a signal converter that converts V-by-One signals into HDMI signals.

[0069] In some embodiments, the adapter board 20 may be disposed between the main board 10 and the display unit 30 .

[0070] In some embodiments, the adapter board 20 can be integrated with the main board 10, and the two are the same PCB (Printed Circuit Board).

[0071] like Figure 5 As shown, in some embodiments, the display unit 30 further includes a third signal receiving module 310. The third signal is a TTL digital signal. The third signal receiving module 310 is connected between the third signal conversion module 320 and the second signal sending module 230. It is used to receive HDMI signals from the second signal sending module 230 and send the received HDMI signals to the third signal conversion module 320. The third signal conversion module 320 is used to convert the HDMI signals into TTL digital signals.

[0072] It is understandable that the display unit 30 receives the HDMI signal through the third signal receiving module 310, and then converts the HDMI signal into a TTL digital signal through the third signal conversion module 320, and sends the TTL digital signal to the display module 330 for image display.

[0073] The third signal receiving module 310 is a signal receiver. The third signal conversion module 320 is a converter that converts HDMI signals into TTL digital signals. By converting the signals into TTL digital signals, video display can be achieved on the miniLED.

[0074] This application also provides a display device. The display device includes the display structure described in the foregoing embodiments.

[0075] In some embodiments, the first signal conversion module 140 on the mainboard 10 can convert video signals in different types of input signals into a first signal to improve the compatibility of the display device so that it can meet the display requirements of a variety of multimedia devices. The fixed frequency module 150 on the mainboard 10 is used to fix the output frequency of the first signal to ensure the consistency of the output frequency to prevent screen flickering and other phenomena during the display process. The third signal conversion module 320 of the display unit 30 is used to convert the first signal into a third signal to meet the display requirements of the display module 330 and realize screen display.

[0076] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
