Description

[0001] This application is a divisional application. The application number of the original application is 202311316503.5, and the original application date is October 12, 2023. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of electronic technology, and specifically to a display device, a display method, an electronic device and a storage medium. Background Art

[0003] In order to improve the user experience, multiple screens are usually configured in some electronic devices such as mobile phones and tablet computers. For example, a folding screen mobile phone is usually configured with an inner screen and an outer screen, wherein the outer screen is used by the user in a folded state, and the inner screen is used by the user in an unfolded state.

[0004] In some application scenarios, users may need to use the inner screen and the outer screen at the same time. Therefore, it is necessary to configure the folding screen mobile phone with the function of simultaneous display of the inner screen and the outer screen. In the prior art, the system on chip (System on Chip, SoC) is usually configured with two independent mobile industry processor interface (Mobile Industry Processor Interface, MIPI) interfaces. The SoC can transmit display data to the inner screen and the outer screen respectively through the two independent MIPI interfaces to achieve simultaneous display of the inner screen and the outer screen. However, with the improvement of screen resolution and refresh rate, higher and higher requirements are placed on the data transmission channel between the SoC and the screen. At the same time, due to the limited number of MIPI interfaces on the SoC (usually only two MIPI interfaces are configured on the SoC), it is impossible to allocate more MIPI interfaces to one screen.

[0005] In response to this problem, one solution in the prior art is to assign the first MIPI interface to the first screen (for example, the external screen) for use, and to selectively assign the second MIPI interface to the first screen or the second screen (for example, the internal screen) for use through a switch. Specifically, when the first screen is needed to display, the second MIPI interface can be assigned to the first screen for use through a switch, so that the first screen can simultaneously receive data sent by the first MIPI interface and the second MIPI interface, thereby improving the resolution and refresh rate of the first screen. When the second screen is needed to display, the second MIPI interface can be assigned to the second screen for use through a switch, so that the second screen can receive data sent by the second MIPI interface. However, the configuration method of the MIPI interface causes the first screen and the second screen to be unable to display at the same time.

[0006] It should be pointed out that the information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art.

[0073] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0074] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0075] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0076] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0077] See also Figures 1A-1C , is a schematic diagram of the structure of a folding screen mobile phone provided in an embodiment of the present application. Among them, Figure 1A is a front view of the foldable screen mobile phone 100 in the unfolded state. Figure 1B This is a schematic diagram of the back of the foldable screen mobile phone 100 in the unfolded state. Figure 1C Schematic diagram of the folding process of the folding screen mobile phone 100. Figures 1A-1C As shown, a first screen 101 (inner screen) is provided on the front of the foldable screen mobile phone 100, and a second screen 102 (outer screen) is provided on the back of the foldable screen mobile phone 100. Generally, when the foldable screen mobile phone 100 is in an unfolded state, it can be displayed through the first screen 101; when the foldable screen mobile phone 100 is in a folded state, it can be displayed through the second screen 102. In addition, in some application scenarios, the first screen 101 and the second screen 102 can also be displayed at the same time.

[0078] It should be pointed out that Figures 1A-1C The folding screen mobile phone shown is only a possible application scenario of the embodiment of the present application, and should not be used as a limitation on the scope of the present application. For example, in addition to the folding screen mobile phone, the electronic device involved in the embodiment of the present application may also be a folding screen tablet computer; or, although it does not have a folding function, other types of electronic devices that include more than two screens.

[0079] See also Figure 2 , is a schematic diagram of the structure of a display device in the related art. Figure 2As shown, the display device includes SoC, a first screen and a second screen. Among them, two independent MIPI interfaces are configured on the SoC. For the convenience of explanation, the two independent MIPI interfaces are respectively referred to as the first MIPI interface (including connection terminals DSI0-L0, DSI0-L1, DSI0-L2, DSI0-L3 and DSI0-CLK) and the second MIPI interface (including connection terminals DSI1-L0, DSI1-L1, DSI1-L2, DSI1-L3 and DSI1-CLK). In addition, a display driver chip (Display Driver IC, DDIC) is configured on each screen. For the convenience of explanation, the display driver chip on the first screen is referred to as the first DDIC, and the display driver chip on the second screen is referred to as the second DDIC. Among them, the first MIPI interface is connected to the data receiving interface of the first DDIC so that the display data is sent to the first screen through the first MIPI interface, so that the first screen displays the corresponding picture; the second MIPI interface is connected to the data receiving interface of the second DDIC so that the display data is sent to the second screen through the second MIPI interface, so that the second screen displays the corresponding picture.

[0080] However, in Figure 2 In the display device shown, since each screen is only equipped with one MIPI interface, there are fewer data transmission channels between the SoC and the screen (there are 4 groups of data transmission channels between the SoC and each screen), which cannot meet the requirements of high resolution and high refresh rate of the screen. Especially for larger screens (for example, Figures 1A-1C The internal screen shown here) will further limit the screen resolution and refresh rate.

[0081] See also Figure 3 , is a schematic diagram of the structure of another display device in the related art. Figure 3 As shown, it is Figure 2 The difference is that two display driver chips are configured on the first screen. For the sake of convenience, the two display driver chips on the first screen are respectively referred to as the first DDIC and the second DDIC; the display driver chip on the second screen is referred to as the third DDIC. The first MIPI interface is connected to the data receiving interface of the first DDIC, and the second MIPI interface is connected to the data receiving interfaces of the second DDIC and the third DDIC respectively through the switch module.

[0082] When the first screen is displayed as a single screen, the data transmission channel between the second MIPI interface and the second DDIC can be selected through the switch module, so that the display data can be sent to the first screen through the first MIPI interface and the second MIPI interface at the same time. It can be understood that at this time, the first screen can use 8 groups of data transmission channels at the same time, thereby meeting the requirements of high resolution and high refresh rate of the first screen. When the second screen is displayed as a single screen, the data transmission channel between the second MIPI interface and the third DDIC can be selected through the switch module, so that the display data can be sent to the second screen through the second MIPI interface.

[0083] In addition, each display driver chip on the first screen is responsible for displaying half of the display area of ​​the first screen. If only one display driver chip is working on the first screen, the first screen will only display half of the image or display a distorted screen. Figure 3 In the display device shown, the first screen can be displayed normally only when the two display driver chips on the first screen work at the same time. It can be understood that when the switch module selects the data transmission channel between the second MIPI interface and the second DDIC, the second screen cannot be displayed; when the switch module selects the data transmission channel between the second MIPI interface and the third DDIC, the first screen cannot be displayed. In other words, Figure 3 In the display device shown, the first screen and the second screen cannot be displayed at the same time.

[0084] It should be noted that the number of MIPI interfaces on a SoC is limited, and usually only two MIPI interfaces are configured. In other words, the above problem cannot usually be solved by adding MIPI interfaces.

[0085] See also Figure 4 , is a schematic diagram of the structure of a display device provided in an embodiment of the present application. Figure 4 As shown, the display device includes a chip, a first screen and a second screen. The chip involved in the embodiment of the present application may be the SoC, application processor (AP) or other types of chips mentioned above, and the embodiment of the present application does not specifically limit this.

[0086] Specifically, the chip includes two data transmission interfaces, namely a first data transmission interface and a second data transmission interface. It can be understood that when data is transmitted between the chip and the screen based on the MIPI protocol, the first data transmission interface and the second data transmission interface are both MIPI interfaces. Of course, those skilled in the art can configure other data transmission protocols between the chip and the screen according to actual needs, and the embodiments of the present application do not specifically limit this.

[0087] In a data transmission interface, a plurality of display signal connection terminals (ports for outputting display signals) are generally included. In the embodiment of the present application, the display signal connection terminals in the first data transmission interface are divided into a first display signal connection terminal and a second display signal connection terminal. Among them, the number of the first display signal connection terminals can be one or more, and the number of the second display signal connection terminals can be one or more, and the embodiment of the present application does not specifically limit this.

[0088] For example, in Fig. 9 In the implementation shown, the first data transmission interface is a first MIPI interface, and the first MIPI interface includes 4 groups of display signal connection terminals, namely connection terminals DSI0-L0, DSI0-L1, DSI0-L2 and DSI0-L3. The display signal connection terminals in the first MIPI interface are divided into a first display signal connection terminal and a second display signal connection terminal. Among them, the first display signal connection terminal includes connection terminals DSI0-L0 and DSI0-L1, and the second display signal connection terminal includes connection terminals DSI0-L2 and DSI0-L3. Correspondingly, the second data transmission interface is a second MIPI interface, and the second MIPI interface includes 4 groups of display signal connection terminals, namely connection terminals DSI1-L0, DSI1-L1, DSI1-L2 and DSI1-L3. In an embodiment of the present application, each group of display signal connection terminals in the first MIPI interface and the second MIPI interface are respectively used to transmit a group of differential signals.

[0089] Please continue reading Figure 4 In an embodiment of the present application, the first screen includes two data receiving interfaces, namely a first data receiving interface and a second data receiving interface. The first screen can receive the first display data sent by the chip through the first data receiving interface and the second data receiving interface, and display the corresponding first picture according to the received first display data. Specifically, the first data receiving interface and the second data receiving interface are respectively responsible for the display of half of the display area of ​​the first screen. It can be understood that the first screen can only be displayed normally when the first data receiving interface and the second data receiving interface receive data at the same time. In addition, the second screen includes a data receiving interface, namely a third data receiving interface. The second screen can receive the second display data sent by the chip through the third data interface, and display the corresponding second picture according to the received second display data. It should be pointed out that the first pictures may be the same or different, and the embodiment of the present application does not impose specific restrictions on this.

[0090] In a possible implementation, each data receiving interface in the first screen and the second screen may correspond to a DDIC, that is, a DDIC includes a data receiving interface. Fig. 9In the illustrated implementation, the first DDIC includes a first data receiving interface, the second DDIC includes a second data receiving interface, and the third DDIC includes a third data receiving interface.

[0091] Please continue reading Figure 4 In an embodiment of the present application, the first display signal connection terminal is electrically connected to the first data receiving interface, and the second display signal connection terminal is electrically connected to the first data receiving interface and the second data receiving interface respectively through a first switch. The first switch is used to select the data transmission channel between the second display signal connection terminal and the first data receiving interface, or to select the data transmission channel between the second display signal connection terminal and the second data receiving interface. The second data transmission interface is electrically connected to the second data receiving interface and the third data receiving interface respectively through a second switch, and the second switch is used to select the data transmission channel between the second data transmission interface and the second data receiving interface, or to select the data transmission channel between the second data transmission interface and the third data receiving interface.

[0092] Specifically, when the first screen needs to be displayed on a single screen, the first switch can be controlled to select the data transmission channel between the second display signal connection terminal and the first data receiving interface, so that the display data is sent to the first data receiving interface through the first data transmission interface; the second switch can be controlled to select the data transmission channel between the second data transmission interface and the second data receiving interface, so that the display data is sent to the second data receiving interface through the second data transmission interface. It can be understood that at this time, the first screen can use all the data transmission channels corresponding to the first data transmission interface and the second data transmission interface at the same time, and the amount of data that can be transmitted is large, and the resolution and refresh rate can be greatly improved.

[0093] When the second screen needs to be displayed on a single screen, the second switch can be controlled to select the data transmission channel between the second data transmission interface and the third data receiving interface, so as to send the display data to the third data receiving interface through the second data transmission interface. It can be understood that at this time, the third data receiving interface of the second screen can receive all the data sent by the third data transmission interface. In addition, since the first screen display is not needed, the first data transmission interface can stop sending data.

[0094] When the first screen and the second screen need to be displayed on a dual screen, the first switch can be controlled to select the data transmission channel between the second display signal connection terminal and the second data receiving interface, so that the display data is sent to the first data receiving interface through the first display signal connection terminal, and the display data is sent to the second data receiving interface through the second display signal connection terminal; the second switch is controlled to select the data transmission channel between the second data transmission interface and the third data receiving interface, so that the display data is sent to the second data receiving interface through the second data transmission interface. It can be understood that at this time, the first data receiving interface of the first screen can receive part of the data sent by the first data transmission interface (data sent by the first display signal connection terminal); the second data receiving interface of the first screen can receive part of the data sent by the first data transmission interface (data sent by the second display signal connection terminal); the third data receiving interface of the second screen can receive all the data sent by the third data transmission interface. In other words, the first data transmission interface is split into two parts, one part is used to send data to the first data receiving interface of the first screen, and the other part is used to send data to the second data receiving interface of the first screen, so as to ensure that the first screen can be displayed normally, thereby realizing the dual screen display of the first screen and the second screen.

[0095] It should be pointed out that when dual-screen display is used, the screen resolution and refresh rate requirements are usually not high. Therefore, even if the first data sending interface is split into two parts, used by the first data receiving interface and the second data receiving interface of the first screen respectively, the basic display requirements can be met.

[0096] In a possible implementation, the number of the first display signal connection terminals and the second display signal connection terminals is equal. It can be understood that this setting is more conducive to evenly distributing the display data of the first data transmission interface to the first data receiving interface and the second data receiving interface. Of course, those skilled in the art can set the number of the first display signal connection terminals to be greater or less than the number of the second display signal connection terminals according to actual needs, and the embodiment of the present application does not impose specific restrictions on this.

[0097] In summary, the display device provided in the embodiment of the present application can not only meet the resolution and refresh rate requirements of the screen, but also realize simultaneous dual-screen display of the first screen and the second screen when the number of data transmission interfaces of the chip is limited.

[0098] In actual applications, due to the fact that the wiring between the first switch and the second data receiving interface is too long, and / or the wiring between the second switch and the second data receiving interface is too long, a large parasitic capacitance may be generated on the line between the first switch and / or the second switch and the second data receiving interface, which may affect data transmission.

[0099] See also Figure 5 , is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Figure 5 As shown, the embodiment of the present application is Figure 4 On the basis of the display device shown, a third switch is added. Specifically, the third switch is arranged on the data transmission channel between the second display signal connection terminal and the second data receiving interface, and the third switch is located between the first switch and the second data receiving interface; and, the third switch is arranged on the data transmission channel between the third display signal connection terminal of the second data sending interface and the second data receiving interface, and the third switch is located between the second switch and the second data receiving interface. It can be understood that after adding the third switch, the line between the first switch and the second data receiving interface can be cut off by the third switch, and the line between the second switch and the second data receiving interface can be cut off, so as to avoid the generation of large parasitic capacitance on the line between the first switch, the second switch and the second data receiving interface.

[0100] It should be pointed out that, in practical applications, technicians in this field may only set the third switch between the first switch and the second data receiving interface according to actual needs; or, only set the third switch between the second switch and the second data receiving interface, and the embodiments of the present application do not impose specific restrictions on this.

[0101] In addition, since the number of the third display signal connection terminals in the second data transmission interface is usually multiple, those skilled in the art may also set the third switch on the data transmission channel between some of the third display signal connection terminals and the second data receiving interface according to actual needs. Fig. 9 In the implementation shown, only the third switch (SW3-2, SW3-3) is set on the data transmission channel between the connection terminals DSI1-L0, DSI1-L1 and the second DDIC, and the connection terminals DSI1-L2, DSI1-L3 are directly connected to the second DDIC through the second switch (SW2-4, SW2-5).

[0102] use Figure 5The display device shown, when the first screen needs to be displayed on a single screen, in addition to "controlling the first switch to select the data transmission channel between the second display signal connection terminal and the first data receiving interface; controlling the second switch to select the data transmission channel between the second data sending interface and the second data receiving interface", it is also necessary to control the third switch to select the data transmission channel between the third display signal connection terminal and the second data receiving interface, so as to send the display data to the second data receiving interface through the second data sending interface. When the first screen and the second screen need to be displayed on a dual screen, in addition to "controlling the first switch to select the data transmission channel between the second display signal connection terminal and the second data receiving interface; controlling the second switch to select the data transmission channel between the second data sending interface and the third data receiving interface", it is also necessary to control the third switch to select the data transmission channel between the second display signal connection terminal and the second data receiving interface, so as to send the display data to the second data receiving interface through the second display signal connection terminal.

[0103] It is understandable that when the chip controls the screen to display, in addition to sending display data to the screen, it also needs to send clock data to the screen at the same time. Accordingly, the data transmission interface also includes a clock signal connection terminal.

[0104] See also Figure 6 , is a schematic diagram of the structure of another display device provided in an embodiment of the present application. Figure 6 As shown, the embodiment of the present application is Figure 5 On the basis of the display device shown, a first clock signal connection terminal, a second clock signal connection terminal and a third clock signal connection terminal are added. It should be supplemented that the clock data output by the first data transmission interface matches the display data. In other words, the clock data output by the first clock signal connection terminal and the second clock signal connection terminal matches the display data output by the first display signal connection terminal and the second display signal connection terminal (the clock data output by the first clock signal connection terminal and the second clock signal connection terminal are the same clock data). The clock data output by the second data transmission interface matches the display data. In other words, the clock data output by the third clock signal connection terminal matches the display data output by the third display signal connection terminal.

[0105] Specifically, the first data transmission interface includes a first clock signal connection terminal and a second clock signal connection terminal. The first clock signal connection terminal is electrically connected to the first data receiving interface so that the clock data is sent to the first data receiving interface through the first clock signal connection terminal; the second clock signal connection terminal is electrically connected to the second data receiving interface through a fourth switch. The fourth switch is used to turn on or off the connection between the second clock signal connection terminal and the second data receiving interface so that the clock signal is selectively sent to the second data receiving interface through the second clock signal connection terminal.

[0106] For example, in Fig. 9 In the implementation shown, the first clock signal connection terminal is DSI0-CLK0, and the second clock signal connection terminal is DSI0-CLK1.

[0107] As described above, when the first screen needs to be displayed on a single screen, the first data receiving interface receives the display data sent by the first display signal connection terminal and the second display signal connection terminal; the second data receiving interface receives the display data sent by the third display signal connection terminal. It can be understood that at this time, the second data receiving interface should receive the clock data sent by the third clock signal connection terminal. Therefore, the fourth switch is controlled to disconnect the connection between the second clock signal connection terminal and the second data receiving interface to prevent the clock data output by the second clock signal connection terminal from interfering with the second data receiving interface. When the first screen and the second screen need to be displayed on a dual screen, the first data receiving interface receives the display data sent by the first display signal connection terminal; the second data receiving interface receives the display data sent by the second display signal connection terminal. It can be understood that at this time, the second data receiving interface should receive the clock data sent by the second clock signal connection terminal. Therefore, the fourth switch is controlled to conduct the connection between the second clock signal connection terminal and the second data receiving interface so that the clock signal is sent to the second data receiving interface through the second clock signal connection terminal.

[0108] In some possible implementations, the third switch and the fourth switch may belong to the same switch module. This configuration can save the number of switch components on the one hand, and facilitate the control of the switch on the other hand. Of course, those skilled in the art may also configure the fourth switch as an independent switch according to actual needs, and the present application embodiment does not impose any specific restrictions on this.

[0109] Please continue reading Figure 6In an embodiment of the present application, the second data transmission interface further includes a third clock signal connection terminal. The third clock signal connection terminal is electrically connected to the second data receiving interface and the third data receiving interface respectively through a fifth switch. The fifth switch is used to select the data transmission channel between the third clock signal connection terminal and the second data receiving interface, or to select the data transmission channel between the third clock signal connection terminal and the third data receiving interface, so as to selectively send the clock signal to the second data receiving interface or the third data receiving interface through the third clock signal connection terminal. Exemplarily, in Fig. 9 In the illustrated implementation, the third clock signal connection terminal is DSI1-CLK.

[0110] As described above, when the first screen needs to be displayed on a single screen, the first data receiving interface receives the display data sent by the first display signal connection terminal and the second display signal connection terminal; the second data receiving interface receives the display data sent by the third display signal connection terminal. It can be understood that at this time, the second data receiving interface should receive the clock data sent by the third clock signal connection terminal. Therefore, the fifth switch is controlled to select the data transmission channel between the third clock signal connection terminal and the second data receiving interface, so that the clock signal is sent to the second data receiving interface through the third clock signal connection terminal. When the first screen and the second screen are required to be displayed on a dual screen, the first data receiving interface receives the display data sent by the first display signal connection terminal; the second data receiving interface receives the display data sent by the second display signal connection terminal; and the third data receiving interface receives the display data sent by the third display signal connection terminal. It can be understood that at this time, the third data receiving interface should receive the clock data sent by the third clock signal connection terminal. Therefore, the fifth switch is controlled to select the data transmission channel between the third clock signal connection terminal and the third data receiving interface, so that the clock signal is sent to the third data receiving interface through the third clock signal connection terminal.

[0111] In some possible implementations, the second switch and the fifth switch may belong to the same switch module. This configuration can save the number of switch components on the one hand, and facilitate the control of the switch on the other hand. Of course, those skilled in the art may also configure the fifth switch as an independent switch according to actual needs, and the present application embodiment does not impose any specific restrictions on this.

[0112] As mentioned above, when the wiring is too long, it will generate large parasitic capacitance, which may affect data transmission. It is understandable that the clock data transmission channel between the chip and the screen also has this problem.

[0113] In a possible implementation, the fourth switch can be set between the fifth switch and the second data receiving interface, and the line between the fifth switch and the second data receiving interface is cut off by the fourth switch to avoid generating a large parasitic capacitance between the fifth switch and the second data receiving interface. That is to say, in an embodiment of the present application, the fifth switch can be directly connected to the second data receiving interface, and can be connected to the second data receiving interface through the fourth switch. It can be understood that when the fifth switch is connected to the second data receiving interface through the fourth switch, the fourth switch can select the data transmission channel between the second clock signal connection terminal and the second data receiving interface, or select the data transmission channel between the third clock signal connection terminal and the second data receiving interface, so as to selectively send the clock signal output by the second clock signal connection terminal or the clock signal output by the third clock signal connection terminal to the second data receiving interface.

[0114] In some possible implementations, those skilled in the art may further provide an independent switch between the fifth switch and the second data receiving interface according to actual needs to cut off the line between the fifth switch and the second data receiving interface. It is understandable that in the embodiment of the present application, the number of switch devices can be saved by using the fourth switch to cut off the line between the fifth switch and the second data receiving interface.

[0115] In the process of the chip controlling the screen display, in addition to sending display data and clock data to the screen, the screen also needs to feedback an interrupt (TE) signal to the chip. This terminal signal is used to inform the chip that the current screen starts to display the picture on the first line, and the chip can start to refresh the next frame of display data.

[0116] Specifically, the chip further includes a first interrupt signal receiving terminal, the first screen further includes a first interrupt signal sending terminal, the first interrupt signal receiving terminal is electrically connected to the first interrupt signal sending terminal, the first interrupt signal receiving terminal is used to receive a first interrupt signal sent by the first interrupt signal sending terminal, the first interrupt signal is used to indicate that the next frame of display data of the first screen can be refreshed. The chip further includes a second interrupt signal receiving terminal, the second screen further includes a second interrupt signal sending terminal, the second interrupt signal receiving terminal is electrically connected to the second interrupt signal sending terminal, the second interrupt signal receiving terminal is used to receive a second interrupt signal sent by the second interrupt signal sending terminal, the second interrupt signal is used to indicate that the next frame of display data of the second screen can be refreshed.

Figure 7As shown, the electronic device includes a display device, which is any one of the display devices in the above embodiments. For the specific content of the display device, please refer to the description of the above embodiments, and for the sake of simplicity, it will not be repeated here.

[0119] Corresponding to the above embodiment, the embodiment of the present application also provides a display method.

[0122] The first display mode involved in the embodiment of the present application is a single-screen display of the first screen. It can be understood that when "the first switch selects the data transmission channel between the second display signal connection terminal and the first data receiving interface; the second switch selects the data transmission channel between the second data sending interface and the second data receiving interface", the chip can send display data to the first data receiving interface through the first display signal connection terminal and the second display signal connection terminal, and send display data to the second data receiving interface through the third display signal connection terminal, so that the first screen displays the display data sent by the first data sending interface and the second data sending interface.

[0123] In a possible implementation, when the display device includes a third switch (eg Figure 5 The display method further includes: in the first display mode, controlling the third switch to select the data transmission channel between the third display signal connection terminal and the second data receiving interface. That is to say, in the first display mode, in addition to "controlling the first switch to select the data transmission channel between the second display signal connection terminal and the first data receiving interface; controlling the second switch to select the data transmission channel between the second data transmission interface and the second data receiving interface", it is also necessary to control the third switch to select the data transmission channel between the third display signal connection terminal and the second data receiving interface, so that the chip can send display data to the second data receiving interface through the third display signal connection terminal.

[0124] In a possible implementation, when the display device includes a fourth switch (eg Figure 6The display method further includes: in the first display mode, controlling the fourth switch to disconnect the connection between the second clock signal connection terminal and the second data receiving interface. That is, in the first display mode, in addition to "controlling the first switch to select the data transmission channel between the second display signal connection terminal and the first data receiving interface; controlling the second switch to select the data transmission channel between the second data transmission interface and the second data receiving interface", it is also necessary to control the fourth switch to disconnect the connection between the second clock signal connection terminal and the second data receiving interface to prevent the clock data output by the second clock signal connection terminal from interfering with the second data receiving interface.

[0125] Further, when the display device includes a fifth switch (eg Figure 6 The display method further includes: in the first display mode, controlling the fifth switch to select the data transmission channel between the third clock signal connection terminal and the second data receiving interface.

[0126] Furthermore, when the fourth switch is set on the data transmission channel between the third clock signal connection terminal and the second data receiving interface, and the fourth switch is located between the fifth switch and the second data receiving interface, the display method also includes: in the first display mode, controlling the fourth switch to select the data transmission channel between the third clock signal connection terminal and the second data receiving interface, so as to send the clock signal output by the third clock signal connection terminal to the second data receiving interface.

[0127] Step S802: in the second display mode, controlling the second switch to select the data transmission channel between the second data transmission interface and the third data receiving interface, and the second screen is used to display the display data sent by the second data transmission interface.

[0128] The second display mode involved in the embodiment of the present application is a second screen single screen display. It can be understood that when the second switch selects the data transmission channel between the second data transmission interface and the third data receiving interface, the chip can send display data to the third data receiving interface through the second data transmission interface, so that the second screen displays the display data sent by the second data transmission interface.

[0129] In a possible implementation, when the display device includes a fifth switch (eg Figure 6 The display method further includes: in the second display mode, controlling the fifth switch to select the data transmission channel between the third clock signal connection terminal and the third data receiving interface. That is, in the second display mode, in addition to "controlling the second switch to select the data transmission channel between the second data transmission interface and the third data receiving interface", it is also necessary to control the fifth switch to select the data transmission channel between the third clock signal connection terminal and the third data receiving interface, so as to send the clock signal to the third data receiving interface through the third clock signal connection terminal.

[0130] Step S803: In the third display mode, control the first switch to enable the data transmission channel between the second display signal connection terminal and the second data receiving interface; control the second switch to enable the data transmission channel between the second data sending interface and the third data receiving interface, the first screen is used to display the data sent by the first data sending interface, and the second screen is used to display the display data sent by the second data sending interface.

[0131] The third display mode involved in the embodiment of the present application is a dual-screen display of the first screen and the second screen. It can be understood that when "the first switch selects the data transmission channel between the second display signal connection terminal and the second data receiving interface; the second switch selects the data transmission channel between the second data sending interface and the third data receiving interface", the chip can send display data to the first data receiving interface through the first display signal connection terminal, and send display data to the second data receiving interface through the second display signal connection terminal, so that the first screen displays the data sent by the first data sending interface; send display data to the second data receiving interface through the second data sending interface, so that the second screen displays the display data sent by the second data sending interface.

[0132] In a possible implementation, when the display device includes a third switch (eg Figure 5 The display method further includes: in the third display mode, controlling the third switch to select the data transmission channel between the second display signal connection terminal and the second data receiving interface. That is to say, in the third display mode, in addition to "controlling the first switch to select the data transmission channel between the second display signal connection terminal and the second data receiving interface; controlling the second switch to select the data transmission channel between the second data transmission interface and the third data receiving interface", it is also necessary to control the third switch to select the data transmission channel between the second display signal connection terminal and the second data receiving interface, so that the chip can send display data to the second data receiving interface through the second display signal connection terminal.

[0133] In a possible implementation, when the display device includes a fourth switch (eg Figure 6 The display method further includes: in the third display mode, controlling the fourth switch to conduct the connection between the second clock signal connection terminal and the second data receiving interface. That is to say, in the third display mode, in addition to "controlling the first switch to conduct the data transmission channel between the second display signal connection terminal and the second data receiving interface; controlling the second switch to conduct the data transmission channel between the second data transmission interface and the third data receiving interface", it is also necessary to control the fourth switch to conduct the connection between the second clock signal connection terminal and the second data receiving interface, so that the chip can send clock data to the second data receiving interface through the second clock signal connection terminal.

[0134] Further, when the display device includes a fifth switch (eg Figure 6 The display method further includes: in the third display mode, controlling the fifth switch to select the data transmission channel between the third clock signal connection terminal and the third data receiving interface. That is to say, in the third display mode, in addition to "controlling the first switch to select the data transmission channel between the second display signal connection terminal and the second data receiving interface; controlling the second switch to select the data transmission channel between the second data transmission interface and the third data receiving interface; controlling the fourth switch to conduct the connection between the second clock signal connection terminal and the second data receiving interface", it is also necessary to control the fifth switch to select the data transmission channel between the third clock signal connection terminal and the third data receiving interface, so that the chip can send clock data to the third data receiving interface through the third clock signal connection terminal.

[0135] Further, when the fourth switch is set on the data transmission channel between the third clock signal connection terminal and the second data receiving interface, and the fourth switch is located between the fifth switch and the second data receiving interface, the display method also includes: in the third display mode, controlling the fourth switch to select the data transmission channel between the second clock signal connection terminal and the second data receiving interface so as to send the clock signal output by the second clock signal connection terminal to the second data receiving interface.

[0136] In a possible implementation, in the third display mode, the first display data is sent to the first data receiving interface and the second data receiving interface through the first data sending interface, so that the first screen displays the first picture corresponding to the first display data; the second display data is sent to the third data receiving interface through the second data sending interface, so that the second screen displays the second picture corresponding to the second display data. The first picture and the second picture can be the same or different, and the embodiment of the present application does not specifically limit this.

[0138] For ease of understanding, the technical solution provided in the embodiment of the present application is described in detail below in conjunction with a specific implementation method.

[0139] See also Fig. 9 , is a schematic diagram of the structure of another display device provided in an embodiment of the present application.

The connection terminal DSI1-L3 is electrically connected to the first DDIC through SW1-2 on one path, and is electrically connected to the second DDIC through SW1-2 and SW3-3 on the other path. By controlling SW1-2 and SW3-3, the display data output by DSI1-L3 can be selectively sent to the first DDIC or the second DDIC. The connection terminal DSI0-CLK1 is electrically connected to the second DDIC through SW3-1. By controlling SW3-1, the clock data output by DSI0-CLK1 can be selectively sent to the second DDIC. The connection terminal DSI1-CLK is electrically connected to the second DDIC through SW2-1 and SW3-1 in one way, and is electrically connected to the third DDIC through SW2-1 in another way. By controlling SW2-1 and SW3-1, the clock data output by DSI1-CLK can be selectively sent to the second DDIC or the third DDIC.

[0143] See also Fig.10 , is a schematic diagram of signal transmission for a first screen single-screen display provided in an embodiment of the present application. Among them, Fig.10 The solid line between the SoC and the screen represents data flow transmission, and the dotted line represents data flow transmission. Fig.10 As shown, by controlling SW1-1 and SW1-2 in the first switch module, the connection terminals DSI0-L2 and DSI0-L3 in the first MIPI interface are connected to the data transmission channel between the first DDIC. The SoC can send clock data and display data to the first DDIC through DSI0-CLK0, DSI0-L0, DSI0-L1, DSI0-L2 and DSI0-L3 in the first MIPI interface. By controlling SW2-1, SW2-2, SW2-3, SW2-4 and SW2-5 in the second switch module, and SW3-1, SW3-2 and SW3-3 in the third switch module, the connection terminals DSI1-CLK, DSI1-L0, DSI1-L1, DSI1-L2 and DSI1-L3 in the second MIPI interface are connected to the data transmission channel between the second DDIC. SoC can send clock data and display data to the second DDIC through DSI1-CLK, DSI1-L0, DSI1-L1, DSI1-L2 and DSI1-L3 in the second MIPI interface. It can be understood that at this time, the first screen can use all data transmission channels corresponding to the first MIPI interface and the second MIPI interface at the same time, and the amount of data that can be transmitted is large, and the resolution and refresh rate can be greatly improved.

[0144] See also Fig.11 , is a schematic diagram of a software framework for a first screen single-screen display provided in an embodiment of the present application. Fig.11As shown, when the first screen needs to be displayed on a single screen, the application App is in Display1 mode, wherein Display1 mode is the display mode of the first screen, and in Display1 mode, it matches the resolution and parameter configuration of the first screen. Similarly, SF and the display driver layer are also in Display1 mode. The display data sent by the application App is processed by SF and the display driver layer, and then transmitted to the first DDIC and the second DDIC through the first MIPI interface DSI0 and the second MIPI interface DSI1 respectively. Since the first screen transmits data through two MIPI interfaces, it has a large data carrying capacity and can support higher resolutions and refresh rates. In addition, the first screen can also feedback the first interrupt signal TE1 through the first DDIC and the second DDIC to prompt the application App to start refreshing the next frame of display data of the first screen.

[0145] See also Fig.12 , is a schematic diagram of signal transmission for a second screen single-screen display provided in an embodiment of the present application.

The SoC can send clock data and display data to the third DDIC through DSI1-CLK, DSI1-L0, DSI1-L1, DSI1-L2 and DSI1-L3 in the second MIPI interface, and the second screen displays the corresponding picture. In addition, since the second screen does not need to use the first MIPI interface, the first MIPI interface can stop outputting data when the second screen is displayed on a single screen.

[0146] See also Fig.13 , is a schematic diagram of a software framework for a second screen single-screen display provided in an embodiment of the present application. Fig.13As shown, when the second screen needs to be displayed on a single screen, the application App is in Display2 mode, where Display2 mode is the display mode of the second screen. In Display2 mode, it matches the resolution and parameter configuration of the second screen. Similarly, SF and the display driver layer are also in Display2 mode. The display data sent by the application App is processed by SF and the display driver layer, and then transmitted to the third DDIC through the second MIPI interface DSI1. In addition, the second screen can also feedback the second interrupt signal TE2 through the third DDIC to prompt the application App to start refreshing the next frame of display data of the second screen.

[0147] See also Fig.14 , is a schematic diagram of signal transmission for dual-screen display of a first screen and a second screen provided in an embodiment of the present application. Among them, Fig.14 The solid line between the SoC and the screen represents data flow transmission, and the dotted line represents data flow transmission. Fig.14 As shown, by controlling SW1-1 and SW1-2 in the first switch module, and SW3-1, SW3-2 and SW3-3 in the third switch module, the connection terminals DSI0-L2, DSI0-L3 and DSI0-CLK1 in the first MIPI interface are connected to the data transmission channel between the second DDIC. The SoC can send clock data and display data to the first DDIC through DSI0-CLK0, DSI0-L0, DSI0-L1 in the first MIPI interface; and send clock data and display data to the second DDIC through the connection terminals DSI0-L2, DSI0-L3 and DSI0-CLK1 in the first MIPI interface. In other words, the first MIPI interface can support the Split function, which can split the first MIPI interface into two groups of data transmission channels, transmitting different data to the first DDIC and the second DDIC respectively.

[0148] In addition, by controlling SW2-1, SW2-2, SW2-3, SW2-4 and SW2-5 in the second switch module, the connection terminals DSI1-CLK, DSI1-L0, DSI1-L1, DSI1-L2 and DSI1-L3 in the second MIPI interface are connected to the data transmission channel between the third DDIC. The SoC can send clock data and display data to the third DDIC through DSI1-CLK, DSI1-L0, DSI1-L1, DSI1-L2 and DSI1-L3 in the second MIPI interface.

[0149] See also Fig.15 , is a schematic diagram of a software framework for dual-screen display of a first screen and a second screen provided in an embodiment of the present application. Fig.15As shown, when the first screen and the second screen need to be displayed on a dual screen, the application App can be in Display1 mode or Display2 mode. Among them, Display1 mode is the display mode of the second screen, in Display1 mode, it matches the resolution and parameter configuration of the first screen; Display2 mode is the display mode of the second screen, in Display2 mode, it matches the resolution and parameter configuration of the second screen.

[0150] If the current application App is in Display1 mode, the application App can send corresponding display data to SF according to the Display1 mode. SF creates a first Surface layer corresponding to the Display1 mode according to the display data sent by the application App, and then copies a second Surface layer corresponding to the Display2 mode according to the first Surface layer. The display data corresponding to the first Surface layer is processed by the display driver layer and transmitted to the first DDIC and the second DDIC respectively through the first MIPI interface DSI0. In addition, the first screen can also feedback the first interrupt signal TE1 through the first DDIC and the second DDIC to prompt the application App to start refreshing the next frame of display data of the first screen. The display data corresponding to the second Surface layer is processed by the display driver layer and transmitted to the third DDIC through the second MIPI interface DSI1. In addition, the second screen can also feedback the second interrupt signal TE2 through the third DDIC to prompt the application App to start refreshing the next frame of display data of the second screen.

[0151] It can be understood that in the embodiment of the present application, the first screen displays the first screen corresponding to the first Surface layer, and the second screen displays the second screen corresponding to the second Surface layer. Since the second Surface layer is a layer obtained by copying the relevant data in the first Surface layer, the display content of the first screen and the second screen is the same. In addition, since the resolution or size of the first screen and the second screen is different, the resolution and size of the second screen and the second screen may be different. It should be pointed out that those skilled in the art can also put the application App in Display2 mode according to actual needs, and the application App can send corresponding display data to SF according to the Display2 mode. SF creates a second Surface layer corresponding to the Display2 mode according to the display data sent by the application App, and then copies a first Surface layer of the Display1 mode according to the second Surface layer. Its specific working principle can be found in the description of the above embodiment, and for the sake of brevity, it will not be repeated here.

[0152] See also Fig.16 , is a schematic diagram of a software framework for another dual-screen display of a first screen and a second screen provided in an embodiment of the present application. Fig.15 The difference between the illustrated embodiments is that, in the embodiments of the present application, the application layer includes two applications, namely, a first application App1 and a second application App2. Among them, the first application App1 is in Display1 mode, wherein the Display1 mode is the display mode of the first screen, and in Display1 mode, it matches the resolution and parameter configuration of the first screen. The first display data sent by the first application App1 is processed by SF and the display driver layer, and then transmitted to the first DDIC and the second DDIC through the first MIPI interface DSI0 and the second MIPI interface DSI1, respectively, so that the first screen displays the first picture. The second application App2 is in Display2 mode, wherein the Display2 mode is the display mode of the second screen, and in Display2 mode, it matches the resolution and parameter configuration of the second screen. The second display data sent by the second application App2 is processed by SF and the display driver layer, and then transmitted to the third DDIC through the second MIPI interface DSI1, so that the second screen displays the second picture.

[0153] In the embodiment of the present application, since the first screen displayed on the first screen and the second screen displayed on the second screen are display data sent by different applications, the display contents of the first screen and the second screen can be different. Of course, the first application App1 and the second application App2 can also send display data corresponding to the same screen, so that the display contents of the first screen and the second screen are the same, and the embodiment of the present application does not specifically limit this.

[0154] It is understandable that in the embodiment of the present application, the switch module needs to have a switching function; the first MIPI interface needs to have a splitting function. For ease of understanding, the working principles are supplemented below.

[0155] See also Fig.17 , is a connection logic diagram of a switch module provided in an embodiment of the present application; see Fig.18 , is a switching logic diagram of a switch module provided in an embodiment of the present application.

The switch module can control interface A to select which path to connect to according to the received control signal (the control signal sent by SoC or AP), so that part or all of the connection terminals in interface A are selectively connected to interface B or interface C.

[0156] It should be noted that MIPI is a differential signal, and each path consists of two signals, one at the N pole and one at the P pole. For example, in interface A, the connection terminal A-CK-N / A-CK-P represents two connection terminals, namely, the N pole connection terminal A-CK-N and the P pole connection terminal A-CK-P, which will not be described in detail in the embodiments of the present application.

The connection terminals DSI0-CK0-N / P, DSI0-L0-N / P and DSI0-L1-N / P are connected to the first DDIC as a group, and the connection terminals DSI0-CK1-N / P, DSI0-L2-N / P and DSI0-L3-N / P are connected to the second DDIC as a group. In other words, one MIPI interface is split into two groups, and different data are transmitted to the first DDIC and the second DDIC respectively.
