[0016] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0018] Figure 1 is a schematic diagram showing a connection relationship of components according to an exemplary embodiment;

[0019] Figure 2 is a schematic diagram of another component according to an exemplary embodiment. DETAILED DESCRIPTION

[0020] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0021] refer to Figure 1 , is a schematic diagram showing the connection relationship of a component, the component comprising:

[0022] The processor 1 has a first output interface TX1 and a first input interface RX1.

[0023] The graphics processing unit 2 is connected to the processor 1 and has a second input interface RX2 and a second output interface TX2. The second input interface RX2 is connected to the first output interface TX1, and the second output interface TX2 is connected to the first input interface RX1.

[0024] The processor 1 also has a third output port TX3.

[0025] The display 3 is connected to the third output port TX3 in the processor 1, and is used for receiving and displaying the signal output by the third output interface.

[0026] The display component can be applied to electronic devices, which may include mobile electronic devices and fixed electronic devices. The mobile electronic devices may include mobile phones, tablet computers, laptop computers, wearable devices, smart homes, etc.

[0027] The processor 1 can be used as a processor of an electronic device, including a central processing unit (CPU) as a computing core and a control core of the system of the electronic device, or can be other processors with processing and control functions.

[0028] The reference and model of the processor 1 are not limited and can be determined according to actual usage requirements. The processors used in different electronic devices can be different.

[0029] The processor 1 has the function of outputting a signal related to an image. Before displaying an image or video through a display, the processor 1 generates and outputs a signal for displaying the display, and the signal is referred to as a first signal. The first signal may include a signal of an image or video to be displayed, and is used for displaying an image, including an image signal and a video signal. The display may display an image or video based on the first signal.

[0030] Exemplarily, the first signal may be a MIPI signal transmitted by a mobile industry processor interface (MIPI).

[0031] The way in which the processor 1 outputs the signal of the image or video to be displayed is not limited, and the signal may be output through a related output interface, or may be output through a related output interface based on a corresponding output protocol.

[0032] The processor 1 has a first output interface TX1, which can be used to output a signal of an image or video to be displayed. The first output interface TX1 can be an output interface with a preset transmission protocol. When a signal is transmitted through the first output interface TX1, the first output interface TX1 can be based on the transmission of signals between the preset transmission protocols.

[0033] Exemplarily, the type of the first output interface TX1 is not limited, for example, a mobile industry processor interface (Mobile Industry Processor Interface, MIPI).

[0034] The graphics processing unit 2 may be any unit with image processing functions. The graphics processing unit (GPU) has the function of processing graphic data and can perform relevant processing on received image signals or video signals, such as frame insertion or definition conversion, thereby accelerating the graphics rendering speed and improving the image quality.

[0035] The model and parameters of the graphics processing unit 2 are not limited and can be determined according to actual usage requirements.

[0036] Exemplarily, various image processors may also serve as a graphics processing unit.

[0037] The graphics processing unit 2 is connected to the processor 1, and receives the first signal output by the processor 1, and can be used to perform graphics processing on the first signal to obtain a second signal. The graphics processing here can be various image processing, such as interpolation or other image processing, and is not limited.

[0038] The graphics processing unit 2 can also return the first signal to the processor 1 without the first signal undergoing graphics processing by the graphics processing unit. In this case, the graphics processing unit 2 plays the role of transmitting the first signal, and the first signal passes through the graphics processing unit 2, but the graphics processing unit 2 does not perform any graphics processing on the first signal.

[0039] The second input interface RX2 in the graphics processing unit 2 is connected to the first output interface TX1 in the processor 1, and the second output interface TX2 is connected to the first input interface RX1. When the first signal enters the graphics processing unit 2 from the second input interface RX2, the first signal after being processed by the graphics processing unit 2 is output from the second output interface TX2, that is, the second signal is output from the second output interface TX2. The first signal is also output from the second output interface TX2 when it is not processed by the graphics processing unit 2.

[0040] The second input interface RX2 and the second output interface TX2 may be output interfaces with a preset transmission protocol. When signals are transmitted through the second input interface RX2 and the second output interface TX2, the second input interface RX2 and the second output interface TX2 may transmit signals based on the preset transmission protocol.

[0041] Exemplarily, the transmission protocol and interface type of the first output interface TX1 , the second input interface RX2 , and the second output interface TX2 are the same.

[0042] Exemplarily, the second input interface RX2 and the second output interface TX2 may be mobile industry processor interfaces (MIPI).

[0043] Since the graphics processing unit 2 includes various circuits, and the circuits include various electronic components, the graphics processing unit 2 has impedance, and the second signal obtained by the graphics processing unit 2 performing graphics processing on the first signal has some loss and attenuation relative to the first signal. For example, after passing through the impedance, the driving level will be reduced, and the high-frequency component and the low-frequency component of the signal will be attenuated.

[0044] Exemplarily, the impedance of GPU 2 includes internal switch impedance.

[0045] Similarly, when the graphics processing unit 2 does not perform graphics processing on the first signal, the graphics processing unit 2 returns the first signal to the processor 1 after receiving the first signal. Since there is a corresponding transmission line between the second input interface RX2 and the second output interface TX2 of the graphics processing unit 2, the transmission line also has impedance, which will also cause the drive level, high-frequency component and / or low-frequency component of the output first signal to change. For example, after passing through the impedance, the drive level will be reduced, and the high-frequency component and low-frequency component of the first signal will be attenuated.

[0046] In summary, after the signal output by the processor 1 through the first output interface TX1 is input to the graphics processing unit 2, the signal output by the graphics processing unit 2 to the processor 1 after graphics processing or transmission by the graphics processing unit 2 will change in terms of driving information and signal components, such as loss and reduction, compared to the signal output by the processor 1 through the first output interface TX1 that is not input to the graphics processing unit 2. If the signal output by the graphics processing unit 2 is input to the display 3, the display 3 may have an error in signal recognition, resulting in abnormal display. After the driving information changes, although the signal content included in the signal does not change, the output effect of the signal will change, thereby affecting the normal reception of the signal by the display 3.

[0047] Since the graphics processing unit 2 is connected to the processor 1 and the signal output by the graphics processing unit 2 is transmitted to the processor 1, the processor 1 can receive the signal output by the graphics processing unit 2 through the first input interface RX1, such as the second signal or the signal output by the graphics processing unit 2 through the second output interface TX2 when the first signal does not undergo graphics processing by the graphics processing unit 2.

[0048] The processor 1 can output a signal of an image or video to be displayed through a first input interface RX1. The first input interface RX1 can be an output interface with a preset transmission protocol. When a signal is transmitted through the first input interface RX1, the first input interface RX1 can be based on the transmission of the signal between the preset transmission protocols.

[0049] Exemplarily, the first input interface RX1 may be, for example, a Mobile Industry Processor Interface (MIPI). The transmission protocol of the first input interface RX1 is the same as that of the first output interface TX1.

[0050] The processor 1 can process the output signal of the graphics processing unit 2 received through the first input interface RX1, including processing the second signal output by the graphics processing unit 2 and the first signal returned by the graphics processing unit to obtain a third signal.

[0051] The processor 1 can output the processed signal to the display 3 through the third output interface TX3. The display 3 is connected to the third output interface TX3, and is used to receive and display the signal output by the third output interface TX3.

[0052] The processor 1 has a function of processing the output signal of the graphics processing unit 2 received through the first input interface RX1. Since the first signal is sent by the processor 1, the processor 1 can determine the output parameters of the first signal. The output parameters include driving information, high-frequency components, low-frequency components, etc., and can also include other information used for signal output except for the output content. The driving information includes the driving level, which can be the amplitude of the driving level.

[0053] For example, the processor can perform pre-emphasis processing on the output signal of the graphics processing unit 2 received through the first input interface RX1 in a pre-emphasis manner, including enhancing the high-frequency component and increasing the amplitude of the rising edge and the falling edge of the high-frequency component in the signal. In this way, the amplitude reduction of the signal caused by the loss and attenuation of the signal through the graphics processing unit 2 can be reduced, thereby reducing the difficulty of the display 3 in identifying the signal.

[0054] The process by which the processor 1 adjusts the output parameters of the second signal or the signal returned by the graphics processing unit 2 is not limited, and the adjustment may be performed by software, by hardware, or by a combination of software and hardware.

[0055] Exemplarily, the signal content included in the first signal is the same as the signal content included in the third signal. When the first signal is not processed by the graphics processing unit 2, the signal content transmitted by the graphics processing unit 2 to the processor 1 is the same as the signal content included in the first signal.

[0056] The signal transmitted from the graphics processing unit 2 to the processor 1 when the first signal is not subjected to graphics processing by the graphics processing unit 2 can be recorded as a third signal. The image information and / or video information included in the third signal does not change relative to the image information and / or video information included in the first signal, that is, the signal content included in the first signal and the third signal does not change, and what changes is the driving information, signal components or other output parameters.

[0057] After receiving the third signal, the processor 1 adjusts the driving information, high-frequency components, and low-frequency components of the third signal, and then outputs them to the display 3 through the third output interface TX3. After receiving the second signal, the processor 1 adjusts the driving information, high-frequency components, and low-frequency components of the second signal, and then outputs them to the display 3 through the third output interface TX3.

[0058] Due to the impedance in the graphics processing unit 2, the signal to be displayed output by the processor 1 will be lost after passing through the graphics processing unit 2, resulting in reduced signal quality. The signal processed by the graphics processing unit 2 is processed by the processor 1 again, and then the signal returned to the processor 1 is output to the display 3 through the processor 1. In this way, the quality of the signal output to the display 3 is improved, the influence of the signal loss caused by the graphics processing unit 2 on the signal is reduced, thereby reducing the influence of the signal input to the display 3, reducing the situation where the display cannot display normally due to large signal loss, improving the display effect, and improving the user experience.

[0059] In one embodiment, the high-frequency signal component of the signal output by the third output interface TX3 is greater than the high-frequency signal component of the signal output by the second output interface TX2. By increasing the amplitude of the rising edge and the falling edge of the high-frequency component in the signal, the amplitude reduction of the signal caused by the loss and attenuation of the signal by the graphics processing unit 2 can be reduced, thereby reducing the difficulty of the display 3 in identifying the signal.

[0060] Exemplary, reference Figure 1 The first signal, the second signal and the third signal may be MIPI signals transmitted by a mobile industry processor interface (MIPI). For example, the first signal is a MIPI1 signal, the second signal is a MIPI2 signal, and the third signal is a MIPI3 signal.

[0061] In one embodiment, when the first signal is not subjected to graphics processing by the graphics processing unit 2, the processor 1 is further used to send a signal of an image or video to be displayed to the display 3, and the display 3 can display according to the received signal.

[0062] When the signal of the image or video to be displayed does not need graphics processing by the graphics processing unit 2, the processor 1 does not send the signal of the image or video to be displayed to the graphics processing unit 2, but sends the signal of the image or video to be displayed to the display 3, and the display 3 can receive the signal of the image or video to be displayed directly transmitted by the processor 1. In this way, the signal of the image or video to be displayed can be transmitted without passing through the graphics processing unit 2, thereby reducing the influence of the graphics processing unit 2 on the signal of the image or video to be displayed, reducing the loss of the signal of the image or video to be displayed, and improving the signal quality of the signal of the image or video to be displayed, so as to facilitate the display 3 to receive and identify the signal of the image or video to be displayed and display according to the signal of the image or video to be displayed, thereby improving the user experience.

[0063] refer to Figure 1 , the connection line between the processor 1 and the display 3 indicates that the processor 1 sends the signal of the image or video to be displayed directly to the display 3.

[0064] In one embodiment, the first signal, the second signal and the third signal are all image signals or video signals. Exemplarily, the video signal may include an image signal, and the video signal may also include an image signal and an audio signal.

[0065] In one embodiment, the graphics processing unit 2 includes:

[0066] The first circuit has a first input terminal and a first output terminal, wherein the first input terminal is connected to the second input interface RX2, and the first output terminal is connected to the second output interface TX2.

[0067] The first circuit is used to transmit the signal output by the first output interface TX1 from the second input interface RX2 to the second output interface TX2 when the signal of the image or video to be displayed does not need to be processed by the graphics processing unit 2. The signal output by the first output interface TX1 includes the signal of the image or video to be displayed.

[0068] Figure 1 The structure of the first circuit is not shown in the figure, and the first circuit may include a transmission line, one end of the transmission line is a first input end, and the other end is a first output end. Exemplarily, the transmission line may be a line capable of transmitting MIPI signals.

[0069] Exemplarily, when the signal of the image or video to be displayed does not need to be processed by the graphics processing unit 2, the first circuit is in a conducting state, so that the first circuit can transmit the signal of the image or video to be displayed from the second input interface RX2 to the second output interface TX2.

[0070] Exemplarily, when the signal of the image or video to be displayed needs to be processed by the graphics processing unit 2, the first circuit is in a disconnected state. The first circuit will not transmit the signal of the image or video to be displayed from the second input interface RX2 to the second output interface TX2. In this case, the first circuit no longer plays a role in transmission.

[0071] In one embodiment, the graphics processing unit 2 includes:

[0072] The second circuit has a second input terminal and a second output terminal, wherein the second input terminal is connected to the second input interface RX2, and the second output terminal is connected to the second output interface TX2.

[0073] The second circuit is used to perform graphics processing on the signal output by the first output interface TX1 when the signal of the image or video to be displayed needs to be processed by the graphics processing unit 2. The signal output by the first output interface TX1 includes the signal of the image or video to be displayed.

[0074] Figure 1 The structure of the second circuit is not shown in the figure, and the second circuit can be any circuit with a graphics processing function, which is not limited here. It can also be any graphics processing module with a graphics processing function, and the graphics processing module includes a circuit with a graphics processing function.

[0075] Exemplarily, when the signal of the image or video to be displayed needs to be processed by the graphics processing unit, the second circuit is in the on state. In this state, the first circuit processes the off state. The graphics processing unit 2 performs graphics processing on the signal of the image or video to be displayed, and outputs the processed signal to the processor 1 through the second output interface TX2.

[0076] Exemplarily, when the signal of the image or video to be displayed does not need to be processed by the graphics processing unit, the second circuit is in an off state. In this state, the graphics processing unit 2 does not perform graphics processing on the signal of the image or video to be displayed. The first circuit processes the on state, and transmits the signal of the image or video to be displayed from the second input interface RX1 to the second output interface TX2 through the first circuit.

[0077] Exemplarily, the second circuit is connected in parallel with the first circuit, and the first circuit is used to short-circuit the second circuit when it is turned on. The circuit structure of the first circuit and the second circuit is not limited and can be determined according to actual usage requirements. In different graphics processing units 2, the structures of the first circuit and the second circuit may be different.

[0078] The first circuit and the second circuit both have impedances, and in the process of the signal of the image or video to be displayed passing through the first circuit and the second circuit, the impedance of the first circuit and the second circuit will affect the signal of the image or video to be displayed. For example, the driving level and / or the high-frequency component may be reduced. After the driving level and / or the high-frequency component are reduced, if they are input to the display, the display may have recognition errors, resulting in the display being unable to display the corresponding content normally. The processor 1 can adjust the driving level and / or high-frequency component of the signal passing through the first circuit and the second circuit to be the same as the signal of the image or video to be displayed output through the first input interface TX1, that is, to be the same as the signal of the image or video to be displayed before it passes through the graphics processing unit 2.

[0079] In one embodiment, reference Figure 1 , the display assembly further comprises:

[0080] The first transmission line A has two ends connected to the processor 1 and the graphics processing unit 2, connected to the processor 1 through the first output interface TX1, and connected to the graphics processing unit 2 through the second input interface RX2. The first transmission line A is used to transmit the signal of the image or video to be displayed output through the first output interface TX1 from the processor 1 to the graphics processing unit 2.

[0081] The second transmission line B has two ends connected to the processor 1 and the graphics processing unit 2, connected to the graphics processing unit 2 through the second output interface TX2, and connected to the processor 1 through the first input interface RX1. The second transmission line B is used to return the signal output by the graphics processing unit 2 to the processor 1.

[0082] The third transmission line C has two ends connected to the processor 1 and the display 3, connected to the processor 1 through the third output interface TX3, and connected to the display 3 through the third input interface RX3. The third transmission line C is used to transmit the signal output through the third output interface TX3 from the processor 1 to the display 3.

[0083] In one embodiment, the processor 1 comprises:

[0084] The processing circuit has a third input terminal and a third output terminal, wherein the third input terminal is at least connected to the first input interface RX1, and the third output terminal is at least connected to the third output interface TX3. The processing circuit is used to adjust the high-frequency component of the signal output by the received graphics processing unit 2 to be the same as the high-frequency component of the signal output by the first output interface TX1.

[0085] Figure 1The processing circuit is not shown in the figure, and the circuit structure of the processing circuit is not limited. It can be a processing circuit including a triode or a MOS tube, or a circuit of other structures, as long as it has the function. The processing circuit includes Figure 1 The internal switching circuit is shown.

[0086] In one embodiment, an electronic device is also provided, including:

[0087] A component in any of the above embodiments.

[0088] Electronic devices may include mobile electronic devices and fixed electronic devices. Mobile electronic devices may include mobile phones, tablet computers, laptops, wearable devices, smart homes, etc.

[0089] In one embodiment, after years of development, the field of mobile phone displays has made great progress. Currently, high-resolution and high-refresh rate screens such as 2K120HZ have been developed. However, to support continuous high-resolution and high-refresh rate display effects, a large amount of CPU and GPU resources will be occupied, which will have a great impact on the power consumption of the entire mobile phone. Therefore, dynamic refresh rate technology has also been developed.

[0090] refer to Figure 2 , which is a schematic diagram of another component. After the graphics processing unit 2 (such as the interpolation chip) is adopted, the interpolation chip will switch to the bypass mode when it is not working. In this mode, the driving ability of the interpolation chip for the MIPI signal cannot be adjusted, and the parasitic impedance (including the internal switch impedance) is large, which will seriously affect the quality of the MIPI signal. MIPI1 is the signal of the image or video to be displayed output by the CPU, and MIPI3 is the signal obtained after the signal of the image or video to be displayed passes through the graphics processing unit 2. RX is the input interface of the graphics processing unit 2, and TX is the output interface of the graphics processing unit 2. Figure 1 The scheme shown in Figure 2 The solution shown in the figure is optimized by optimizing the link architecture of the MIPI signal. When in Bypass mode, the MIPI signal of the graphics processing unit (such as the X7 independent graphics processor) can be transmitted back to the CPU. The CPU receives the signal from the X7 and then directly outputs it to the display by adjusting transmission parameters such as output drive high capability and pre-emphasis, thereby reducing the problem of excessive signal loss in the independent graphics card.

[0091] Add a MIPI switch. When in Bypass mode, MIPI DSI0 can be switched to connect directly to the screen, shortening the routing path and reducing the routing impedance. In PT mode, MIPI DSI0 is switched to the interpolation chip for interpolation. This solution reduces MIPI signal transmission loss by optimizing the architecture.
