[0002] With the development of display technologies, the resolution of screens has been continuously increasing. A single display driver integrated circuit (DDIC) cannot support the high-resolution requirements of screens. Therefore, two DDICs are required to drive one display screen. Generally, a display apparatus may be configured with one or more display screens to provide a display function. For a display apparatus configured with multiple display screens, such as a triple-fold device, at least three DDICs are required to drive the display. However, the system-on-chip (SoC) platform of the display apparatus supports at most two DDICs to simultaneously output displays, and cannot meet the application requirements of more DDICs working simultaneously. Summary of the Invention

Detailed implementation manners

[0024] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, the first display driving module may be referred to as the second display driving module, and similarly, the second display driving module may be referred to as the first display driving module. Both the first display driving module and the second display driving module are display driving modules, but they are not the same display driving module.

[0027] It can be understood that for "connection" in the following embodiments, if there is transmission of electrical signals or data between the connected circuits, modules, units, etc., it should be understood as "electrical connection", "communication connection", etc.

At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0030] With the rapid development of foldable display devices, multi-fold devices are constantly emerging, and the screen resolution is continuously increasing. In future triple-fold devices, the screen resolution further increases, resulting in a single DDIC being unable to support the high screen resolution requirements. Therefore, it is inevitable that two DDICs are required on one screen. At the same time, some forms of triple-fold devices are equipped with a secondary display, so there are three DDICs in the whole machine. However, the SOC platform in the related art can support a maximum of only two DDICs to display output simultaneously, and cannot meet the scenario requirements of two screens and three DDICs working simultaneously.

[0031] To solve the above problems, the present application provides a display device and a display apparatus. The display apparatus includes a display device and a display panel connected to the display device. The display apparatus may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, an e-reader, a handheld computer, an electronic display screen, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) / virtual reality (VR) device, a media player, a smart wearable device, etc. The display apparatus may also be a foldable device, such as a foldable mobile phone, a foldable tablet computer, a foldable computer, etc.

[0032] As Figure 1 shown, the display device provided by the embodiment of the present application includes a processing module, a display driving module 120, a first switching module 130, and a second switching module 140. The processing module may include at least one of an Application Processor (AP), a Graphics Processing Unit (GPU), a Digital Signal Processor (DSP), etc. The processing module is configured with at least two display conversion interface groups. Each display conversion interface group, as a whole, may be pre-configured. Each display conversion interface group includes a plurality of interfaces, and each interface is used to transmit signals supporting the operation of the display driving module 120, and each interface complies with the Mobile Industry Processor Interface (MIPI) protocol. Exemplarily, the display conversion interface group may be a DSI (Display Serial Interface), such as 2-channel (Line) DSI or 4Line DSI, or a CSI (Camera Serial Interface), etc. The types of the interfaces in the same display conversion interface group are the same. Exemplarily, the display conversion interface group includes a plurality of D-PHY interfaces or a plurality of C-PHY interfaces.

[0033] The display driving module 120 is connected to the display panel. The display driving module 120 includes a plurality of display driving modules, and each display driving module is used to drive any display area in the display panel to display correspondingly. Among them, the display driving module can be a DDIC. The display area can be understood as the area where the display device performs display. During application, the display panel can be configured with one or more display screens, and one display screen can correspond to at least one display area. Specifically, the display driving module 120 at least includes a first display driving module 121, a second display driving module 122, and a third display driving module 123. Among them, the first display driving module 121 is connected to the first sub-interface group 111a in the first display conversion interface group 111. During application, the first display driving module 121 is configured with a plurality of interfaces, and some interfaces of the first display driving module 121 are correspondingly connected to a plurality of interfaces in the first sub-interface group 111a one by one. The first display driving module 121 can support the corresponding display area to display under the action of the processing module. Among them, the first sub-interface group 111a includes a plurality of interfaces for display. Exemplarily, the first sub-interface group 111a includes a clock signal interface and at least one data signal interface, where the clock signal interface is used to transmit the clock signal, and the data signal interface is used to transmit the data signal.

[0034] A plurality of first ends of the first switch module 130 are respectively correspondingly connected to the second sub-interface group 111b in the first display conversion interface group 111. A plurality of second ends of the first switch module 130 are respectively correspondingly connected to a plurality of interfaces of the first display driving module 121 and the second display driving module 122. Among them, the first display conversion interface group 111 is one of at least two display conversion interface groups. The second sub-interface group 111b is different from the first sub-interface group 111a, and the second sub-interface group 111b includes a plurality of interfaces for display. Exemplarily, the second sub-interface group 111b includes a clock signal interface and at least one data signal interface. A plurality of first ends of the second switch module 140 are respectively correspondingly connected to a plurality of interfaces of the second display conversion interface group 112, and a plurality of second ends of the second switch module 140 are respectively correspondingly connected to a plurality of interfaces of the second display driving module 122 and the third display driving module 123. Among them, the second display conversion interface group 112 is one of at least two display conversion interface groups. The second switch module 140 and the first switch module 130 can be multi-pole multi-throw switches.

[0035] Among them, the processing module is respectively connected to the first switch module 130 and the second switch module 140. The processing module is used to control the on-off states of the first switch module 130 and the second switch module 140, so as to control any one or simultaneously control multiple display driving modules to drive the corresponding display areas in the display panel to display. Specifically, the processing module is connected to the control end of the first switch module 130, and the processing module is used to control the on-off state of the first switch module 130, so as to control the on-off states between the first display driving module 121, the second display driving module 122 and the processing module respectively. The processing module is connected to the control end of the second switch module 140, and the processing module is used to control the on-off state of the second switch module 140, so as to control the on-off states between the second display driving module 122, the third display driving module 123 and the processing module respectively.

[0036] In an application, the first display driving module 121 directly drives the corresponding display area to display under the action of the processing module, or when the first switch module 130 turns on the first display driving module 121 and the second sub-interface group 111b, the first display driving module 121 drives the corresponding display area to display under the action of the processing module. When the first switch module 130 turns on the second display driving module 122 and the second sub-interface group 111b, or when the second switch module 140 turns on the second display driving module 122 and the second display conversion interface group 112, the second display driving module 122 drives the corresponding display area to display under the action of the processing module. When the second switch module 140 turns on the third display driving module 123 and the second display conversion interface group 112, the third display driving module 123 drives the corresponding display area to display under the action of the processing module.

[0037] The above display device includes a processing module, a display driving module 120, a first switch module 130, and a second switch module 140. Among them, the first display driving module 121 is connected to the first sub-interface group 111a of the first display conversion interface group 111. The first display driving module 121 and the second display driving module 122 are connected to the second sub-interface group 111b of the first display conversion interface group 111 through the first switch module 130. The third display driving module 123 is connected to the second display conversion interface group 112 through the second switch module 140. Based on this, the processing module can independently control the working states of the respective display driving modules by controlling the conduction states of the respective switch modules, so as to control the display states of the display areas corresponding to the respective display driving modules. Moreover, when the first switch module 130 conducts the second display driving module 122 and the second sub-interface group 111b, and the second switch module 140 conducts the third display driving module 123 and the second display conversion interface group 112, the processing module can control the first display driving module 121, the second display driving module 122, and the third display driving module 123 to work simultaneously, thereby driving the corresponding three display areas in the display panel to display, realizing that at least three display driving modules work simultaneously, solving the problem in the related art that at most two display driving modules are supported to work, and being applied to a display device with multiple display screens, and being able to meet the application requirements of simultaneous display of multiple display screens.

[0038] Please continue to refer to Figure 1 , in an embodiment, when the first switch module 130 conducts the processing module and the second display driving module 122, and the second switch module 140 conducts the processing module and the third display driving module 123, that is, when the first switch module 130 conducts the path between the second sub-interface group 111b of the first display conversion interface group 111 and the second display driving module 122, and the second switch module 140 conducts the second display conversion interface group 112 and the third display driving module 123, the first display driving module 121 and the second display driving module 122 are used to jointly drive the first display area and the second display area to display under the action of the processing module, and the third display driving module 123 is used to drive the third display area to display under the action of the processing module. Among them, the first display area is used to display under the drive of the first display driving module 121, the second display area is used to display under the drive of the second display driving module 122, and the third display area is used to display under the drive of the third display driving module 123.

[0039] Exemplarily, the display panel includes a first display screen and a second display screen. Among them, the first display screen includes a first display area and a second display area, and the second display screen includes a third display area. Among them, the first display area is connected to the first display driving module 121, the second display area is connected to the second display driving module 122, and the third display area is connected to the third display driving module 123. In an application, when the first switch module 130 conducts the path between the processing module and the second display driving module 122, and the second switch module 140 conducts the path between the processing module and the third display driving module 123, the first display area and the second display area support the display of the first display screen under the common driving of the first display driving module 121 and the second display driving module 122, and the third display area supports the display of the second display screen under the driving of the third display driving module 123.

[0040] For the above display device, the processing module controls the first switch module 130 to conduct the path between the second display driving module 122 and the processing module, and controls the second switch module 140 to conduct the path between the third display driving module 123 and the processing module, so as to realize the simultaneous operation of at least three display driving modules, namely the first display driving module 121, the second display driving module 122 and the third display driving module 123, thereby realizing the simultaneous display of at least three display areas in the display panel, namely the first display area, the second display area and the third display area. Exemplarily, when the display panel includes a first display screen and a second display screen, and the first display screen includes a first display area and a second display area, and the second display screen includes a third display area, the first display screen and the second display screen in the display panel can be simultaneously displayed by the common operation of three display driving modules.

[0041] Please continue to refer to Figure 1 , in one embodiment, when the first switch module 130 conducts the path between the processing module and the second display driving module 122, and the second switch module 140 conducts the path between the processing module and the third display driving module 123, the display refresh frequency of the third display area is greater than the display refresh frequencies of the first display area and the second display area. That is, the display refresh frequency of the third display area is greater than the display refresh frequency of the first display area, and the display refresh frequency of the third display area is greater than the display refresh frequency of the second display area. In this way, it is possible to support different display refresh frequencies for multiple display areas of the display panel, improving the display performance of the display device.

[0042] Exemplarily, when the first switch module 130 conducts the processing module and the second display driving module 122, and the second switch module 140 conducts the processing module and the third display driving module 123, the display refresh frequency of the first display area is the same as that of the second display area, and the display refresh frequencies of the first display area and the second display area are both less than that of the third display area. Exemplarily, the display refresh frequencies of the first display area and the second display area are 60 Hz, and the display refresh frequency of the third display area is 120 Hz. When applied to a display panel, if the first display area and the second display area correspond to the first display screen of the display panel, the display refresh frequency of the first display screen is 60 Hz. If the third display area corresponds to the second display screen of the display panel, the display refresh frequency of the second display screen is 120 Hz.

[0043] Please continue to refer to Figure 1 , in one embodiment, the interface of the first display driving module 121 connected to the first switch module 130 is different from the interface of the first display driving module 121 connected to the first sub-interface group 111a. Exemplarily, some interfaces of the first display driving module 121 are correspondingly connected to multiple interfaces of the first sub-interface group 111a one by one, and the remaining interfaces of the first display driving module 121 are correspondingly connected to multiple second ends of the first switch module 130 one by one. Among them, when the first switch module 130 conducts the processing module and the first display driving module 121, and the second switch module 140 conducts the processing module and the second display driving module 122, the first display driving module 121 and the second display driving module 122 are used to jointly drive the first display area and the second display area to display simultaneously under the action of the processing module, and the third display driving module 123 is in a disconnected state from the processing module. At this time, the third display driving module 123 does not work, and the third display area corresponding to the third display driving module 123 does not display. In this way, the first display driving module 121 and the second display driving module 122 can operate together, while the third display driving module 123 does not operate, so as to realize the joint driving of two display areas, that is, the first display area and the second display area. When applied to a display panel, if the first display screen of the display panel includes the first display area and the second display area, it can support the independent display of the first display screen.

[0044] Please continue to refer to Figure 1, in one embodiment, the display refresh frequency of the first display area and the second display area in the first state is less than that in the second state. Among them, the first state is the state where the first switch module 130 conducts the processing module and the second display driving module 122, and the second switch module 140 conducts the processing module and the third display driving module 123. The second state is the state where the first switch module 130 conducts the processing module and the first display driving module 121, and the second switch module 140 conducts the processing module and the second display driving module 122.

[0045] In the application, the interface of the first display driving module 121 connected to the first switch module 130 is different from the interface of the first display driving module 121 connected to the first sub-interface group 111a, and the number of interfaces of the second display driving module 122 for connecting to the second switch module 140 is more than the number of interfaces for connecting to the first switch module 130. Based on this, the number of interfaces of the first display driving module 121 connected to the processing module in the first state is less than the number of interfaces connected to the processing module in the second state, and the number of interfaces of the second display driving module 122 connected to the processing module in the first state is less than the number of interfaces connected to the processing module in the second state.

[0046] Exemplarily, in the first state, the display refresh frequency of the first display area and the second display area is 60 Hz, and in the second state, the display refresh frequency of the first display area and the second display area is 120 Hz; when applied to a display panel, such as when the first display area and the second display area correspond to the first display screen of the display panel, the display refresh frequency of the first display screen in the first state is 60 Hz, and the display refresh frequency of the first display screen in the second state is 120 Hz.

[0047] The above display device realizes that the same display area supports different display refresh frequencies by respectively controlling the conduction states of the first switch module 130 and the second switch module 140 through the processing module, enabling the display panel to support display at different display refresh frequencies and improving the display performance of the display device.

[0048] Please continue to refer to Figure 1, in one embodiment, when the first switch module 130 disconnects the first display driving module 121 and the second display driving module 122 from the second sub-interface group 111b respectively, and the second switch module 140 conducts the third display driving module 123 and the second display conversion interface group 112, the third display driving module 123 drives the third display area to display under the action of the processing module. In this case, the first display driving module 121 can drive the first display area to display under the action of the processing module, and the second display driving module 122 is in a disconnected state from the processing module and does not operate. Correspondingly, the second display area does not display. Thus, by controlling the on / off states of the first switch module 130 and the second switch module 140 through the processing module, independent driving of a single display area such as the third display area can be achieved. When applied to a display panel, for example, when the second display screen of the display panel includes a third display area, independent display of the second display screen can be supported.

[0049] For better understanding, as Figure 2 shown, the display device includes an application processor (AP), three DDICs (DDIC1-1, DDIC1-2, and DDIC-2), a first switch module 130, and a second switch module 140. Among them, the application processor is configured with a dual-channel DSI interface (DSI0 and DSI1), and each DSI interface includes at least one clock signal interface (DSI-CLK) and four data signal interfaces (DSI-D). Among them, the first sub-interface group 111a includes the clock signal interface DSI0-CLK0 and two data signal interfaces DSI0-D0, DSI0-D1. The second sub-interface group 111b includes the clock signal interface DSI0-CLK1 and two data signal interfaces DSI0-D2, DSI0-D3.

[0050] Among them, the clock signal interface CLK of DDIC1-1 is connected to the clock signal interface DSI0-CLK0 of DSI0, and the two data interfaces D0 and D1 of DDIC1-1 are respectively and correspondingly connected to the two data signal interfaces DSI0-D0 and DSI0-D1 of DSI0. The control end of the first switch module 130 is connected to the application processor. Multiple first ends of the first switch module 130 are respectively and correspondingly connected to DSI0-CLK1, DSI0-D2, and DSI0-D3. Multiple second ends of the first switch module 130 are respectively and correspondingly connected to the two data signal interfaces D2 and D3 of DDIC1-1. Multiple other second ends of the first switch module 130 are respectively and correspondingly connected to the clock signal interface CLK, and the two data signal interfaces D0 and D1 of DDIC1-2. The control end of the second switch module 140 is connected to the application processor. Multiple first ends of the second switch module 140 are respectively and correspondingly connected to DSI1-CLK, DSI1-D0 to DSI1-D3. Multiple second ends of the second switch module 140 are respectively and correspondingly connected to the clock signal interface CLK of DDIC1-2, the four data signal interfaces D0 to D3 of DDIC1-2, and the clock signal interface CLK of DDIC-2, and the four data signal interfaces D0 to D3 of DDIC-2.

[0051] Moreover, DDIC1-1 and DDIC1-2 are respectively connected to the first display screen of the display panel. DDIC1-1 corresponds to the first display area of the first display screen, DDIC1-2 corresponds to the second display area of the first display screen, DDIC1-2 is connected to the second display screen of the display panel, and DDIC1-2 corresponds to the third display area of the second display screen.

[0052] Based on Figure 2 In the shown structure, in the application, the application processor controls the first switch module 130 to conduct the path between DDIC1-1 and DSI0 (DSI0-D2, DSI0-D3), and controls the second switch module 140 to conduct the path between DDIC1-2 and DSI1 (DSI1-CLK, DSI1-D0 to DSI1-D3). In this case, the application processor supports the common operation of DDIC1-1 and DDIC1-2 with a full-rate (4Line) interface, thereby supporting the first display screen of the display panel to work independently in a high refresh rate and high resolution working scenario such as 120Hz.

[0053] The application processor controls the first switch module 130 to disconnect the paths between DDIC1-1, DDIC1-2 and DSI0 (DSI0-D2, DSI0-D3) respectively, and controls the second switch module 140 to conduct the path between DDIC-2 and DSI1 (DSI1-CLK, DSI1-D0~D3). In this case, the application processor supports the independent operation of DDIC-2 with a full-rate (4Line) interface, so as to support the second display screen of the display panel to work independently in high refresh rate and high resolution working scenarios such as 120Hz.

[0054] The application processor controls the first switch module 130 to conduct the path between DDIC1-2 and DSI0 (DSI0-D2, DSI0-D3), and controls the second switch module 140 to conduct the path between DDIC-2 and DSI1 (DSI1-CLK, DSI1-D0~D3). In this case, the application processor supports the operation of DDIC1-1 and DDIC1-2 with a non-full-rate (2Line) interface, and supports the operation of DDIC-2 with a full-rate (4Line) interface, so as to support the first display screen of the display panel to work in working scenarios with a refresh rate such as 60Hz and high resolution, and support the second display screen of the display panel to work in high refresh rate and high resolution working scenarios such as 120Hz, thus meeting the scenario requirements for the simultaneous display of the first display screen and the second display screen.

[0055] The above display device controls the conduction states of the first switch module 130 and the second switch module 140 through the processing module, supports the common operation of DDIC1-1 and DDIC1-2, so as to support the first display screen of the display panel to independently display at a higher display refresh rate, and also supports the independent operation of DDIC-2, so as to support the second display screen of the display panel to independently display at a higher display refresh rate, and supports the common operation of DDIC1-1, DDIC1-2 and DDIC-2, so as to support the first display screen of the display panel to display at a lower display refresh rate and the second display screen to display at a higher display refresh rate, thus being able to meet the different display scenario requirements of multi-screen display devices.

[0056] In one embodiment, as Figure 3As shown in the figure, the first switch module 130 includes a first switch unit 131 and a second switch unit 132. Among them, multiple first ends of the first switch unit 131 are respectively connected to the second sub-interface group 111b, and multiple second ends of the first switch unit 131 are respectively connected to multiple interfaces of the first display driving module 121. Multiple first ends of the second switch unit 132 are respectively connected to multiple second ends of the first switch unit 131 and partial second ends of the second switch module 140, and multiple second ends of the second switch unit 132 are respectively connected to multiple interfaces of the second display driving module 122. Among them, the first switch unit 131 and the second switch unit 132 can be multi-throw switches. The processing module is respectively connected to the first switch unit 131 and the second switch unit 132, and is used to control the conduction states of the first switch unit 131 and the second switch unit 132, so as to control any one or simultaneously control multiple display driving modules to drive the corresponding display areas in the display panel to display. In applications, by respectively controlling the conduction states of the first switch unit 131, the second switch unit 132, and the second switch module 140 through the processing module, any one or simultaneously control multiple display driving modules to drive the corresponding display areas in the display panel to display, and by cooperating with the first switch unit 131 and the second switch module 140 through the second switch unit 132, the branch length of the signal can be reduced, the signal integrity of transmitting high-speed signals on the interface path can be improved, and the display effect of the display panel can be further improved.

[0057] In one embodiment, when the first switch unit 131 conducts the processing module and the second switch unit 132, the second switch unit 132 conducts the first switch unit 131 and the second display driving module 122, the second switch unit 132 disconnects the second switch module 140 and the second display driving module 122, and the second switch module 140 conducts the processing module and the third display driving module 123, the first display driving module 121 and the second display driving module 122 are used to jointly drive the first display area and the second display area to display under the action of the processing module, and the third display driving module 123 is used to drive the third display area to display under the action of the processing module. Based on this, in the scenario where three display areas are jointly displayed, by cutting off the signal flow of the second display conversion interface group 112 to the second display driving module 122 through the second switch unit 132, the signal integrity of the second display conversion interface group 112 flowing to the third display driving module 123 is improved, thereby improving the display performance of the display device.

[0058] In one embodiment, when the first switch unit 131 conducts the processing module and the first display driving module 121, and the second switch module 140 conducts the second display driving module 122, the second switch unit 132 conducts the processing module respectively, and the second switch unit 132 conducts the second switch module 140 and the second display driving module 122, and the second switch unit 132 disconnects the first switch unit 131 and the second display driving module 122, the first display driving module 121 and the second display driving module 122 are used to jointly drive the first display area and the second display area to display under the action of the processing module. Based on this, in the scenario where the first display area and the second display area are jointly displayed, the signal flow of the second sub-interface group 111b to the second display driving module 122 is cut off by the second switch unit 132, improving the signal integrity of the second sub-interface group 111b flowing to the first display driving module 121, thereby improving the display performance of the display device.

[0059] In one embodiment, when the first switch module 130 disconnects the processing module and the first display driving module 121, the second switch unit 132 disconnects the first switch unit 131 and the second switch module 140 from the second display driving module 122 respectively, and the second switch module 140 conducts the processing module and the third display driving module 123, the third display driving module 123 is used to drive the third display area to display under the action of the processing module. Based on this, in the scenario where the third display area is independently displayed, the signal flow of the second display conversion interface group 112 to the second display driving module 122 is cut off by the second switch unit 132, improving the signal integrity of the second display conversion interface group 112 flowing to the third display driving module 123, thereby improving the display performance of the display device.

[0060] Exemplarily, as Figure 4 shown, taking the Figure 2 display device shown as an example, wherein, the three first ends of the first switch unit 131 are respectively connected to the clock signal interface DSI0-CLK1 of the second sub-interface group 111b, and the two data signal interfaces DSI-D2, DSI-D3. The three second ends of the first switch unit 131 are respectively connected to the two data signal interfaces D2, D3 of the DDIC1-1 and the three first ends of the second switch unit 132. The three first ends of the second switch unit 132 are also connected to the three second ends of the second switch module 140. The three second ends of the second switch unit 132 are respectively connected to the clock signal interface CLK and the two data signal interfaces D0, D1 of the DDIC1-2.

[0061] Based on Figure 4In the shown structure, during application, the application processor controls the first switch unit 131 to turn on the path between DDIC1-1 and DSI0 (DSI0-D2, DSI0-D3), controls the second switch module 140 to turn on the path between DSI1 (DSI1-CLK, DSI1-D0~D3) and the second switch unit 132, controls the second switch unit 132 to turn on the path between the second switch module 140 and DDIC1-2, and controls the second switch unit 132 to turn off the path between the first switch unit 131 and DDIC-2. In this case, the application processor supports the concurrent operation of DDIC1-1 and DDIC1-2 with a full-rate (4Line) interface, thereby supporting the first display screen of the display panel to work independently in a high refresh rate and high resolution working scenario such as 120Hz.

[0062] The application processor controls the first switch unit 131 to turn off the paths between DDIC1-1 and the second switch unit 132 and DSI0 (DSI0-D2, DSI0-D3), controls the second switch module 140 to turn on the path between DDIC-2 and DSI1 (DSI1-CLK, DSI1-D0~D3), and controls the second switch unit 132 to turn off the paths between the first switch unit 131 and the second switch module 140 and DDIC1-2. In this case, the application processor supports the independent operation of DDIC-2 with a full-rate (4Line) interface, thereby supporting the second display screen of the display panel to work independently in a high refresh rate and high resolution working scenario such as 120Hz.

[0063] The application processor controls the first switch unit 131 to turn on the path between the second switch unit 132 and DSI0 (DSI0-D2, DSI0-D3), controls the second switch module 140 to turn on the path between DDIC-2 and DSI1 (DSI1-CLK, DSI1-D0~D3), controls the second switch unit 132 to turn on the path between the first switch unit 131 and DDIC1-2, and controls the second switch unit 132 to turn off the path between the second switch module 140 and DDIC1-2. In this case, the application processor supports the operation of DDIC1-1 and DDIC1-2 with a non-full-rate (2Line) interface and supports the operation of DDIC-2 with a full-rate (4Line) interface, thereby supporting the first display screen of the display panel to work in a refresh rate and high resolution working scenario such as 60Hz, and supporting the second display screen of the display panel to work in a high refresh rate and high resolution working scenario such as 120Hz, thus meeting the scenario requirements for the simultaneous display of the first and second display screens.

[0064] The above display device can support the independent operation of a display driving module and the simultaneous operation of multiple display driving modules by controlling the conduction states of the first switching unit 131, the second switching unit 132, and the second switching module 140 through a processing module, so as to support the simultaneous or time-sharing display of one or more display areas. Moreover, by cooperating the second switching unit 132 with the first switching unit 131 and the second switching module 140, the branch length of the signal can be reduced, signal bifurcation can be minimized, and the signal integrity during transmission between interfaces can be improved, which is beneficial to enhancing the display performance of the display device.

[0065] Based on the display device 10 provided in the above embodiment, as Figure 5 shown, the present application further provides a display device, which includes the display device 10 and a display panel 20. Among them, the display panel 20 is connected to the display device 10. The display panel 20 includes multiple display areas, and each display area is correspondingly connected to a display driving module. The display area is used for displaying under the drive of the display driving module. For the specific introduction of the display device 10, please refer to the foregoing embodiment and will not be elaborated here.

[0066] The above display device includes the display device 10 and a display panel 20 connected to the display device 10. Among them, the display device 10 includes a processing module, a display driving module group 120, a first switching module 130, and a second switching module 140. Among them, the first display driving module 121 is connected to the first sub-interface group 111a of the first display conversion interface group 111. The first display driving module 121 and the second display driving module 122 are connected to the second sub-interface group 111b of the first display conversion interface group 111 through the first switching module 130. The third display driving module 123 is connected to the second display conversion interface group 112 through the second switching module 140. Based on this, the processing module can control the working states of the respective display driving modules independently by controlling the conduction states of the first switching module 130 and the second switching module 140, so as to control the display states of the display areas corresponding to the respective display driving modules. Moreover, when the first switching module 130 conducts the second display driving module 122 and the second sub-interface group 111b, and the second switching module 140 conducts the third display driving module 123 and the second display conversion interface group 112, the processing module can control the first display driving module 121, the second display driving module 122, and the third display driving module 123 to work simultaneously, so as to drive the corresponding three display areas in the display panel 20 to display, realizing the simultaneous operation of at least three display driving modules, solving the problem in the related art that at most two display driving modules are supported to work, and further being able to meet the application requirements of simultaneous display of multiple display screens.

[0067] Please continue to refer to Figure 5In one embodiment, the display panel 20 includes a first display screen 210 and a second display screen 220. The first display screen 210 includes a first display area 201 and a second display area 202, and the second display screen 220 includes a third display area 203. The first display area 201 is connected to the first display driver module 121 of the display device 10, the second display area 202 is connected to the second display driver module 122 of the display device 10, and the third display area 203 is connected to the third display driver module 123 of the display device 10. The first display screen 210 and the second display screen 220 are used for simultaneous or time-sharing display under the drive of the display device 10. Specifically, when the first display driver module 121 and the second display driver module 122 operate together, the first display area 201 and the second display area 202 are displayed together, and the first display screen 210 is displayed alone. When the third display driver module 123 operates independently, the third display area 203 is displayed independently, and the second display screen 220 is displayed alone. When the first display driver module 121, the second display driver module 122 and the third display driver module 123 operate together, the first display area 201, the second display area 202 and the third display area 203 are displayed together, and the first display screen 210 and the second display screen 220 are displayed simultaneously. In this way, time-sharing display of a single display screen is realized, and simultaneous display of multiple display screens is realized, which meets different display requirements of the display device and improves the display performance of the display device.

[0068] In one embodiment, Figure 6 As shown, the display device further includes a first rotating shaft 231 and a second rotating shaft 232, and the first display screen 210 includes a first sub-display screen 211 and a second sub-display screen 212. The first sub-display screen 211 corresponds to the first display area 201, and the second sub-display screen 212 corresponds to the second display area 202. The first rotating shaft 231 is connected to the first sub-display screen 211 and the second display screen 220, respectively, and the second rotating shaft 232 is connected to the second sub-display screen 212 and the second display screen 220, respectively. The first sub-display screen 211 is used to be folded relative to the second display screen 220 via the first rotating shaft 231, and the second sub-display screen 212 is used to be folded relative to the second display screen 220 via the second rotating shaft 232. That is, the display device is a three-folding display device.

[0069] In the application, when the first sub-display screen 211 and the second display screen 220 are in a folded state, or when the second sub-display screen 212 and the second display screen 220 are in a folded state, that is, when the display device is in a partially folded state, the first display screen 210 (including the first sub-display screen 211 and the second sub-display screen 212) displays independently. When the first sub-display screen 211 and the second display screen 220 are in a folded state and the second sub-display screen 212 and the second display screen 220 are in a folded state, that is, when the display device is in a fully folded state, the second display screen 220 displays independently. When the second display screen 220 is in an unfolded state with the first sub-display screen 211 and the second sub-display screen 212 respectively, that is, when the display device is in a fully unfolded state, the first display screen 210 (including the first sub-display screen 211 and the second sub-display screen 212) and the second display screen 220 display simultaneously.

[0070] The above three-fold display device can be in a partially folded state or a fully folded state, or can be in a fully unfolded state, which enables the device to be flexibly adjusted according to the usage scenario and user needs. And when it is necessary to display the content on different screens separately, different sub-display screens can be folded up and only the content on the corresponding screen is displayed, enabling the user to use the device for various operations more efficiently. And because the device can be folded and unfolded, it can adapt to different usage scenarios. For example, when the device needs to be carried, the device can be folded up for convenient carrying; when the device needs to be used, the device can be unfolded to obtain a larger display area and a better viewing experience, improving the portability, flexibility and operability of the display device.

[0071] In one embodiment, as Figure 7 shown, the display device further includes a third rotating shaft 233, and the third rotating shaft 233 is respectively connected to the first display screen 210 and the second display screen 220. Among them, the first display screen 210 is used to fold relative to the second display screen 220 through the third rotating shaft 233. That is, the display device is a double-fold display device. In the application, when the first display screen 210 and the second display screen 220 are in a folded state, the first display screen 210 or the second display screen 220 displays independently; when the first display screen 210 and the second display screen 220 are in an unfolded state, the first display screen 210 and the second display screen 220 display simultaneously. This kind of double-fold display device can be folded and unfolded, so it can be conveniently switched from one usage state to another to adapt to different usage scenarios; and when it is necessary to display the content on two screens simultaneously, the device can be unfolded and the content on the two screens can be displayed simultaneously. When it is necessary to display the content on two screens separately, one screen can be folded up and only the content on the other screen is displayed, improving the portability, flexibility and operability of the display device.
