The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0048] Terminal devices are feature-rich and have complex internal structures. Many seemingly unrelated functions are actually interconnected. For example, the display driver module of a terminal device is located on a small board. When the display content changes, the audio line, also located on this board, will be interfered with, creating noise. Specifically, audio is the interface for sound input and output of mobile devices. However, audio is an analog circuit, and its detection and pickup of uV-level analog circuit signals are extremely susceptible to interference. For instance, when the display driver chip switches display content, it needs to draw power from the power supply line, causing a sudden increase in current. This generates a square wave signal on the ground line, which interferes with the audio line, ultimately creating noise. To solve the audio noise problem, an interference filtering circuit is needed. Based on this, the first aspect is... (Please refer to the appendix...) Figure 1 and attached Figure 2 At least one embodiment of this disclosure provides a terminal device, wherein an appended Figure 1 In the diagram, the lines between the audio transmission interface 104 and the audio driver chip 103 include a ground line and an audio line. When the external device 105 (e.g., headphones) is connected to the audio transmission interface 104, each line is connected in a one-to-one correspondence. Therefore, the ground line 1051 and the audio line are shown in detail on the external device, while only a signal line is used to illustrate the connection between the audio transmission interface 104 and the audio driver chip 103. Figure 2 The locations of the filter circuits between each line are shown.

[0049] The terminal device includes an audio driver chip 1013 and an audio transmission interface 104. A ground wire 1051 and an audio line are provided between the audio driver chip 1013 and the audio transmission interface 104. A filtering circuit is provided between the ground wire 1051 and the audio line. The filtering circuit is used to prevent the current signal on the ground wire 1051 from being transmitted to the audio line. The current signal is generated by the switching of the display content of the terminal device.

[0050] In this process, the filtering current can be achieved using a capacitor. For the sake of clarity in describing the effect and placement of the filtering circuit, the following content will use "capacitor" to represent the filtering circuit; however, this is not a limitation on the form of the filtering circuit.

[0051] The terminal device includes a motherboard 101 and a small board 103. The motherboard 101 can be located near the top of the terminal device, and the small board 103 can be located near the bottom of the terminal device. The battery 102 of the terminal device can be located between the motherboard 101 and the small board 103. A power management module 1011 can be installed on the motherboard 101. The battery 102 is connected to the power management module 1011, so that the power management module 1011 can supply power to other modules or components. For example, the power management module 1011 can supply power to the motherboard 101 and its modules (such as system chip 1012, audio driver chip 1013, etc.), and it can also supply power to the small board 103 and its modules (such as audio amplifier circuit, display driver module, etc.). As can be seen, all modules on the small board 103 share a power supply line (vph-pwr) from the power management module 1011 to the small board 103. Therefore, when the display driver module switches the display content, it will obtain power from the above power supply line. A current will be generated between the power management module 1011 and the small board 103, and the ground line 1051 of the small board 103 will generate a current signal similar to a square wave (hereinafter referred to as square wave signal). The square wave signal has a rich frequency, and the greater the difference between the display content before and after the switch, the greater the current and the higher the frequency of the square wave signal.

[0052] In addition, the audio transmission interface 104 can both output audio and capture input audio. The audio transmission interface 104 can be a separate headphone jack, or an interface that integrates a headphone jack and a charging port, such as a Type-C interface. The audio transmission interface 104 can be connected to the small board 103, therefore the ground wire 1051 and audio wire between the audio driver chip 1013 and the audio transmission interface 104 can be located between the motherboard 101 and the small board 103.

[0053] As analyzed above, when ground wire 1051 generates a square wave signal, if the frequency exceeds a certain threshold, it will interfere with the audio line and generate noise. However, since there is a capacitor between ground wire 1051 and the audio line, and according to Z = 1 / 2πfc (where Z is the impedance between ground wire 1051 and the audio line, f is the frequency of the square wave, and c is the capacitance), when the capacitance is small, the impedance is infinitely large. Therefore, the anti-wave signal is consumed by the impedance between ground wire 1051 and the audio line and will not be transmitted to the audio line, thus preventing noise generation. However, it should be noted that if the impedance between the ground wire 1051 and the audio line is too high, the spatial signal coupled to the external audio device (e.g., headphones 105) connected to the audio transmission interface 104 will not be able to be transmitted to the ground wire 1051, but will be transmitted to the internal part of the terminal device, thus interfering with the antenna signal of the terminal device. Therefore, it is necessary to prevent the square wave signal of the ground wire 1051 from being transmitted to the audio line, while allowing the spatial signal coupled to the audio line to be transmitted to the ground wire 1051. This requirement can be achieved by adjusting the capacitance value between the audio line and the ground wire 1051. When the capacitance value is set to 5-20nF, it can both prevent the square wave signal of the ground wire 1051 from being transmitted to the audio line and allow the spatial signal coupled to the audio line to be transmitted to the ground wire 1051. Specifically, the impedance of the square wave signal should reach more than 90%, and the transmission rate of the spatial signal should reach more than 90%. Preferably, when the capacitance value is set to 10nF, the impedance of the square wave signal and the transmission rate of the spatial signal can reach more than 95%.

[0054] The terminal device provided in this embodiment, by setting a ground line 1051 and an audio line between the audio driver chip 1013 and the audio transmission interface 104, can realize the control of the audio transmission interface 104 by the audio driver chip 1013, that is, control the audio transmission interface 104 to output audio, or acquire the audio collected by the audio transmission interface 104; and by setting a filter circuit between the ground line 1051 and the audio line, it can prevent the square wave signal on the ground line 1051 from being transmitted to the audio line. In other words, when the display content of the terminal device is switched, the square wave signal generated on the ground line 1051 will not interfere with the audio line, so no noise is generated.

[0055] In some embodiments of this disclosure, the motherboard 101 is provided with a first ground wire 1051 interface connected to the ground wire 1051 and a first audio wire interface connected to the audio wire; the small board 103 is provided with a second ground wire 1051 interface connected to the ground wire 1051 and a second audio wire interface connected to the audio wire; wherein, a capacitor (i.e., a filter circuit) is provided between the first ground wire 1051 interface and the first audio wire interface, and / or, a capacitor (i.e., a filter circuit) is provided between the second ground wire 1051 interface and the second audio wire interface.

[0056] An audio cable is provided between the first and second audio interfaces, and a ground wire 1051 is provided between the first and second ground wire 1051 interfaces. By placing the capacitor between the starting point and / or ending point of the audio cable and the ground wire 1051, the capacitor can be placed on the motherboard 101 and / or the small board 103. This not only improves the convenience of capacitor placement but also increases the performance stability of the capacitor between the ground wire 1051 and the audio cable. Furthermore, no new structure needs to be added between the audio cable and the ground wire 1051 between the motherboard 101 and the small board 103, avoiding excessive installation space occupation. The installation position of the capacitor can be selected according to the location of other components and modules, and this disclosure is not intended to limit this.

[0057] In some embodiments of this disclosure, the audio line includes a microphone line 1052 and / or a channel line, wherein the channel line may include a left channel line 1053 and / or a right channel line 1054.

[0058] Microphone line 1052 is used to acquire input audio, and channel lines are used to output audio. When there are multiple audio lines, such as microphone line 1052 and left channel line 1053, microphone line 1052 and right channel line 1054, left channel line 1053 and right channel line 1054, or microphone line 1052, left channel line 1053 and right channel line 1054, a capacitor is placed between each audio line and ground line 1051. For example, when the audio line includes microphone line 1052, left channel line 1053, and right channel line 1054, a first capacitor C1 can be placed between microphone line 1052 and ground line 1051, a second capacitor C2 can be placed between left channel line 1053 and ground line 1051, and a third capacitor C3 can be placed between right channel line 1054 and ground line 1051. The first capacitor C1 is used to prevent the square wave signal on ground line 1051 from being transmitted to microphone line 1052, the second capacitor C2 is used to prevent the square wave signal on ground line 1051 from being transmitted to left channel line 1053, and the third capacitor C3 is used to prevent the square wave signal on ground line 1051 from being transmitted to right channel line 1054.

[0059] By placing corresponding capacitors between each audio line and the ground line 1051, each audio line can be prevented from being interfered with by the square wave signal of the ground line 1051 and generating noise. In other words, the audio lines will not generate noise when the display content is switched.

[0060] Secondly, at least one embodiment of this disclosure provides a display method applied to a terminal device, please refer to the appendix. Figure 3 It illustrates the process of the method, including steps S301 to S303.

[0061] In step S301, two consecutive frames of display images are acquired.

[0062] Two consecutive display images can be obtained from the processor (CPU) or from the display driver module. These two display images are any two consecutive images during the display process of the terminal device. Since the images are generated and cached in advance, they can be obtained before the display driver module drives the screen to display according to these two images.

[0063] In step S302, switching information is determined based on the two displayed images.

[0064] The switching information can be the current value required by the display driver module to switch between the two display images at a preset speed. Therefore, the current value required by the display driver module to switch between the two display images at a preset speed can be determined based on the difference between the two display images. The difference between the two display images can be the sum of the pixel value differences of corresponding pixels in the two display images. That is, the pixel value difference between each pixel in the previous frame and the corresponding pixel in the next frame is obtained, and the pixel value differences of all pixels are summed to obtain the aforementioned difference. Furthermore, the mapping relationship between the difference and the current value can be preset in advance, thereby determining the current value. It can be understood that the difference is directly proportional to the current value, that is, the larger the difference, the larger the current value, and the smaller the difference, the smaller the current value.

[0065] The higher the current required by the display driver module, the higher the frequency of the square wave generated on the ground wire of the small board when drawing power from the power supply line.

[0066] The preset speed is the standard speed at which images switch between two adjacent frames. It is determined by the frame rate of the display screen and is a fixed value when the frame rate remains unchanged.

[0067] In step S303, in response to the switching information satisfying a preset condition, the switching speed of the two display images is controlled to be lower than a preset speed threshold to prevent the current signal on the ground wire of the terminal device from being transmitted to the audio line, wherein the current signal is generated by the switching of the two display images.

[0068] The switching information meets preset conditions, which can be that the current value required for the display driver module to switch the two display images at a preset speed is higher than a preset current threshold. When the current value is higher than the current threshold, the frequency of the square wave-like current signal (hereinafter referred to as the square wave signal) generated on the ground wire can enable the square wave signal to be transmitted to the audio line, thereby interfering with the audio line and generating noise.

[0069] Furthermore, the preset conditions can be determined based on the parameter values ​​of the filter circuit between the ground wire and the audio line, and the speed threshold is also determined based on the parameter values ​​of the filter circuit between the ground wire and the audio line. When the filter circuit is a capacitor, the parameter of the filter circuit can be the capacitance value. The impedance between the ground wire and the audio line is Z = 1 / 2πfc, where the capacitance value c is fixed. Therefore, f affects the impedance, and the preset conditions and speed threshold can affect f, thereby affecting the impedance. The preset conditions (e.g., current threshold) and speed threshold determined by the capacitance value can prevent the square wave signal from being transmitted from the ground wire to the audio line.

[0070] The following method can be used to control the switching speed between two displayed images: First, generate at least one transition image based on the two images; then, insert the at least one transition image between the two images to form an image sequence, and control the image sequence to switch at a preset speed. In other words, by inserting a transition image, the switching speed between the two images can be slowed down, reducing the frequency of the square wave signal generated on the ground line, while avoiding the display card frame rate problem caused by simply reducing the switching speed.

[0071] In one example, when switching between the first and second images, the differences between each pixel in the first image and its corresponding pixel in the second image are first statistically analyzed, and the different pixels are recorded as pixels to be updated. Then, half of the pixels to be updated are updated to their corresponding pixels in the second image to generate a third image. This third image is then inserted as a transition image between the first and second images and displayed sequentially in the order of the first, third, and second images. The first and third images switch at a preset speed, and the third and second images switch at a preset speed. Therefore, when the first and third images switch at the preset speed, since the switching speed remains the same but the number of updated pixels is halved, the current required by the display driver module to perform the switching is reduced, resulting in a lower frequency of the square wave signal. Similarly, when the third and second images switch at the preset speed, since the switching speed remains the same but the number of updated pixels is halved, the current required by the display driver module to perform the switching is reduced, resulting in a lower frequency of the square wave signal. As can be seen from the above process, the switching speed between adjacent images remains unchanged. However, due to the insertion of a third image, the switching speed between the first and second images is reduced by half. Furthermore, the current required during the switching process is reduced, and the frequency of the generated square wave signal is reduced.

[0072] Thirdly, at least one embodiment of this disclosure provides a display device applied to a terminal device, please refer to the appendix. Figure 4 It shows the structure of the device, including:

[0073] The acquisition module 401 is used to acquire two consecutive display images;

[0074] The determining module 402 is used to determine switching information based on the two displayed images;

[0075] The control module 403 is configured to control the switching speed of the two display images to be lower than a preset speed threshold in response to the switching information meeting preset conditions, so as to prevent the current signal on the ground wire of the terminal device from being transmitted to the audio line, wherein the current signal is generated by the switching of the two display images.

[0076] In some embodiments of this disclosure, the determining module is specifically used for:

[0077] Based on the difference between the two displayed images, determine the current value required for the display driving module to switch the two displayed images at a preset speed;

[0078] The switching information meets preset conditions, including:

[0079] The current value is higher than the preset current threshold.

[0080] In some embodiments of this disclosure, the control module is specifically used for:

[0081] Based on the two image frames, generate at least one transition image frame;

[0082] At least one transition image is inserted between the two image frames to form an image sequence, and the image sequence is controlled to switch at a preset speed.

[0083] In some embodiments of this disclosure, the preset condition is determined based on the parameter values ​​of the filter circuit between the ground wire and the audio line, and / or the speed threshold is determined based on the parameter values ​​of the filter circuit between the ground wire and the audio line.
