Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display system, method, apparatus, medium, device, product and display device. Background Technology

[0002] With the development of display technology, liquid crystal display technology has become increasingly mature and is gradually being applied to scenarios such as virtual reality, augmented reality, and mixed reality to provide images of the virtual world. Typically, a liquid crystal display screen consists of a backlight module, a lower polarizer, a circuit board, a liquid crystal layer, a color filter, and an upper polarizer; among them, an electric field is applied to the circuit board to control the deflection angle of the liquid crystal in the liquid crystal layer, thereby modulating the light transmission intensity.

[0003] Typically, because liquid crystal deflection requires a certain amount of time, illuminating the backlight module before the liquid crystal is fully deflected will cause ghosting, or trailing. Currently, to reduce this trailing phenomenon in LCD displays, black-insertion screens are used. Specifically, the backlight module is off during data transmission and liquid crystal deflection; it is illuminated after data transmission and liquid crystal deflection are complete. However, when the display system includes multiple displays, such as those for the left and right eyes as described above, it can easily lead to excessive instantaneous power consumption, resulting in a high system power load and poor stability.

[0080] This disclosure provides a display system applicable to multi-screen (i.e., display screen, or display panel) display scenarios, such as virtual reality, augmented reality, mixed reality, stereoscopic display, and multi-screen multi-view display scenarios. It uses a signal conversion unit to alternately and cyclically connect the display screens to the processor, thereby achieving time-sharing connection between each display screen and the processor, and time-sharing illumination of each display screen. This reduces peak system power consumption, lowers system power load, and improves system stability. Compared to related technologies, it avoids the problems of high power consumption and poor system stability caused by all display screens simultaneously transmitting data and being illuminated.

[0081] The following description, in conjunction with specific embodiments, exemplarily illustrates the display system, as well as the display control method, display control device, storage medium, electronic device, computer program product, and wearable display device for the system. Based on a comparison with related technologies, the beneficial effects of the technical solutions provided by the embodiments of this disclosure are explained.

[0082] First, combined Figure 1 and Figure 2 The solution for the relevant technologies will be explained.

[0083] Figure 1 This is a schematic diagram of the structure of a display system in related technologies. Figure 2 This is a schematic diagram of a display driver timing in related technologies. (Refer to...) Figure 1 and Figure 2 In related technologies, the display system 01 includes a system main processor 011, a first display screen 012, and a second display screen 013. The first display screen 012 is connected to the system main processor 011 via a signal path, and the second display screen 013 is connected to the system main processor 011 via another signal path. Both the first display screen 012 and the second display screen 013 include their own backup signal paths. Based on this, during data transmission, the MIPI signals of both screens are transmitted simultaneously, meaning the data transmission process starts and ends simultaneously; and the backlight modules of both display screens are lit simultaneously, such as... Figure 2 As shown, this results in a sudden increase in the power consumption of the display system, a large power load on the display system, and system instability.

[0084] To address this, embodiments of this disclosure propose time-division multiplexing of MIPI signals and time-division staggered lighting of the backlight modules of the display screen, in order to reduce the instantaneous power consumption of the display system, reduce the power load, and improve system stability.

[0085] The following explanation is based on the accompanying drawings.

[0086] In some embodiments, Figure 3 This is a schematic diagram of the structure of a display system provided in an embodiment of the present disclosure. Figure 4 In response to Figure 3 The diagram shows a display driving timing diagram of a display system. (Refer to...) Figure 3 and Figure 4 The display system 10 includes a processor 110, a signal conversion unit 130, and at least two display screens 120. The signal conversion unit 130 includes an input terminal 131 and at least two output terminals 132. The input terminal 131 is connected to the processor 110, and the at least two output terminals 132 are connected to the at least two display screens 120 in a one-to-one correspondence. The signal conversion unit 130 is used to alternately and cyclically connect each of the at least two display screens 120 to the processor 110. Correspondingly, each display screen 120 is alternately and cyclically lit up. The number of display screens 120 connected to the processor 110 at a single time is less than the total number of display screens.

[0087] The processor 110 is the main processor of the display system, which controls other components in the display system, such as the signal conversion unit 130 and the display screen 120, to work together so that the display system can meet the display requirements. For example, the processor 110 can output a Mobile Industry Processor Interface (MIPI) signal, in which case the time-division multiplexing data (i.e., signal) is a time-division multiplexing MIPI signal.

[0088] The number of display screens 120 can be represented by N, and the number of display screens 120 that are connected and lit at one time can be represented by M; where N≥2, 1≤M<N, and M and N are both integers. Therefore, the number of display screens 120 is at least two, for example, two, three, or more, meaning N can be 2, 3, 4, or a larger value; correspondingly, the number of display screens 120 that are connected and lit at one time, i.e., M, can be 1, 1, 2, or other values ​​satisfying M<N, which are not limited here. This enables dual-screen or multi-screen collaborative display.

[0089] For example, the display screen 120 may be a liquid crystal display screen, which includes a backlight module; in this embodiment of the disclosure, the display screen 120 lighting up corresponds to the backlight module being lit.

[0090] In this system, the input terminal 131 of the signal conversion unit 130 is connected to the processor 110, and the output terminal 132 is connected to each of the display screens 120. Based on this, by switching the output terminals 132 connected to the input terminal 131 in batches, the signal conversion unit 130 can alternately and cyclically connect the display screens 120 to the processor 110 in batches; and alternately and cyclically illuminate the display modules 120, thereby achieving batch and time-sharing illumination of the display modules 120, avoiding the problem of excessive instantaneous power consumption caused by all display modules 120 illuminating simultaneously in the display system 10. Therefore, by switching the connection relationship between the display screens 120 and the processor 110 through the signal conversion unit 130, the number of display modules 120 transmitting data simultaneously and the number of display modules 120 illuminated simultaneously can be reduced, thereby reducing the instantaneous power consumption during the display process of the display system 10, reducing the load on the system power supply, and improving the overall stability of the system.

[0091] For example, such as Figure 4 As shown, in the screen-on control signals V11, V12, and V13 for each display screen, a high-level signal indicates that the display screen is on. Combined with... Figure 3 and Figure 4 When the display system 10 includes multiple display screens 120, each display screen 120 is connected to the processor through the signal conversion unit 130 in turn and is lit up in turn. Thus, compared with all display screens being lit up at the same time, the maximum instantaneous power consumption can be reduced to 1 / N in the related technology, thereby reducing the instantaneous power consumption of the display system and improving the system stability.

[0092] For example, Figure 5 This is a schematic diagram of another display system provided in an embodiment of the present disclosure. Figure 6 In response to Figure 5 The diagram shows a display driving timing diagram of a display system. (Refer to...) Figure 5 and Figure 6 In the display system 10, the number N of display screens 120 can specifically be 2. Each display screen 120 may include a first display screen 121 and a second display screen 122. Through the switching of the signal conversion unit 130, the first display screen 121 and the second display screen 122 are sequentially and alternately connected to the processor 110, and the first display screen 121 and the second display screen 122 are sequentially and alternately lit. Therefore, in this embodiment of the present disclosure, compared to all display screens lighting up simultaneously, the maximum instantaneous power consumption can be reduced by 1 / 2, thereby reducing the instantaneous power consumption of the display system and improving system stability.

[0093] In the display system 10 provided in this embodiment, by setting a signal conversion unit 130, each display screen 120 in the display system 10 is connected to the processor 110 in a time-division manner. This enables the time-division transmission of signals corresponding to the display screen 120, that is, signals corresponding to multiple display screens 120 are transmitted in the order in which the display screens 120 are connected, instead of being transmitted simultaneously. At the same time, the backlight modules of the display screens 120 are also staggered in time, that is, the display screens 120 (i.e., the backlight modules therein) are lit in a time-division manner, thereby reducing the peak power consumption of the display system 10, reducing the power load of the display system 10, and improving the overall stability of the system.

[0094] In some embodiments, at least two display screens 120 are divided into at least two groups; the signal conversion unit 130 is used to simultaneously connect the display screens 120 in the same group to the processor 110, and to alternately and cyclically connect the display screens 120 in different groups to the processor 110.

[0095] By grouping the display screens 120, the signal conversion unit 130 can simultaneously connect the display screens 120 in the same group to the processor 110 to achieve corresponding signal transmission; furthermore, the display screens 120 in the same group can be lit up at the same time, that is, the lighting start time of the display screens in the same group is the same, and the lighting end time is the same.

[0096] Meanwhile, the signal conversion unit 130 alternately and cyclically connects different groups of display modules 120 to the processor 110, that is, alternately and cyclically transmits signals and alternately and cyclically lights up; thus, while reducing the number of display screens 120 that transmit data at the same time and the number of display screens 120 that light up at the same time, the signal conversion unit 130 has a strong structural regularity and the control method is flexible and convenient.

[0097] For example, in combination Figure 5 When N is 2, the display screen 120 can be divided into two groups, with one display screen 120 in each group.

[0098] For example, in combination Figure 3 When N is 3, the display screen 120 can be divided into two groups, with one display screen 120 in one group and two display screens 120 in the other group. Alternatively, when N is 3, the display screen 120 can be divided into three groups, with one display screen 120 in each group.

[0099] In other embodiments, when N is 4, 5 or greater, the display screen 120 can be divided into 2 groups, 3 groups or more groups, with at least one display screen 120 in each group. The number of display modules 120 in different groups can be the same or different, which is not limited here.

[0100] In some implementations, if at least two display modules 120 are divided into N' groups, and each group of display modules 120 is alternately and cyclically connected to the processor 110 and correspondingly lit up alternately and cyclically through the switching of the signal conversion unit 130, the instantaneous power consumption peak of the display system 10 is reduced to 1 / N', and no further examples will be given.

[0101] In some embodiments, Figure 7 This is a schematic diagram of the structure of another display system provided in an embodiment of the present disclosure. Figure 8 This is a schematic diagram of the structure of yet another display system provided in an embodiment of this disclosure. (In conjunction with...) Figure 7 and Figure 8 The number of signal transmission interfaces 100 at the input terminal 131 of the signal conversion unit 130 is equal to or greater than the number of signal transmission interfaces 100 at the signal output terminal of the processor 110. The number of signal transmission interfaces 100 at each output terminal 132 of the signal conversion unit 130 is equal to or greater than the number of signal transmission interfaces 100 at the signal input terminal of the display screen 120 connected to that output terminal 132. The number of signal transmission interfaces 100 at the signal output terminal of the processor 110 is equal to or greater than the number of signal transmission interfaces 100 at the signal input terminal of a single display screen 120.

[0102] Optionally, the signal output terminals of the processor 110 include P1 signal transmission interfaces 100, the signal input terminals of each display screen 120 include P2 signal transmission interfaces 100, the input terminals of the signal conversion unit 130 include P3 signal transmission interfaces 100, and each output terminal of the signal conversion unit 130 includes P4 signal transmission interfaces 100; wherein, P4 = P3 ≥ P1 ≥ P2 ≥ 1, and P1, P2, P3 and P4 are all integers.

[0103] The number P2 of signal transmission interfaces 100 at the signal input terminal of the display screen 120 can be 1, 2 or a larger value, and can be set based on signal transmission requirements, and is not limited here.

[0104] Among them, the number P1 of signal transmission interfaces 100 at the signal output end of the processor 110 is equal to or greater than the number P2 of signal transmission interfaces 100 at the signal input end of the display screen 120, so as to meet the signal transmission requirements and ensure that the display screen 120 can display normally.

[0105] For example, when P2 = 1, P1 can be 1, 2, 3 or a larger value; when P2 = 2, P1 can be 2, 3, 4 or a larger value, which is not limited here.

[0106] In this system, the number of signal transmission interfaces 100 at each output end of the signal conversion unit 130 is P4; the number of signal transmission interfaces 100 at the input end of the signal conversion unit 130 is P3, which is equal to the number of signal transmission interfaces 100 at a single output end of the signal conversion unit 130, P4, to meet the signal conversion requirements; furthermore, the number of signal transmission interfaces 100 at the input end of the signal conversion unit 130 is equal to or greater than the number of signal transmission interfaces 100 at the signal output end of the processor 110, P1, to meet the signal input requirements; and the number of signal transmission interfaces 100 at the output end of the signal conversion unit 130 is equal to or greater than the number of signal transmission interfaces 100 at the signal input end of the display screen 120, P2, to meet the signal output requirements. Thus, the signal conversion unit 130 can be used to realize the signal conversion between the processor 110 and the display screen 120.

[0107] For example, when P2 = 1, P3 and P4 can both be 1, 2, 3 or larger; when P2 = 2, P3 and P4 can both be 2, 3, 4 or larger, without limitation.

[0108] In other implementations, the number of signal transmission interfaces for each input / output terminal can be flexibly set to meet the needs of signal conversion and structural expansion, which is not limited here.

[0109] In some embodiments, the number of signal transmission interfaces 100 satisfies the following conditions: the number of signal transmission interfaces 100 at the signal output end of the processor 110, the number of signal transmission interfaces 100 at the input end 131 of the signal conversion unit 130, the number of signal transmission interfaces 100 at each output end 132 of the signal conversion unit 130, and the number of signal transmission interfaces 100 at the signal input end of a single display screen 120 are all equal, i.e., P4 = P3 = P2 = P1.

[0110] Optionally, P4 = P3 = P2 = P1 = 2.

[0111] This configuration is designed to meet the application requirements of virtual reality.

[0112] In some embodiments, each signal transmission interface 100 is used to transmit 4 signals.

[0113] This configuration is designed to meet the application requirements of virtual reality, while also satisfying the signal transmission rate requirements, enabling high-speed signal transmission, and thus meeting the display response speed requirements.

[0114] For example, in combination Figure 7 and Figure 8In the display system 10 used in virtual reality scenarios, the processor typically has two MIPI ports and two display screens 120. Each display screen has two MIPI ports, and each port can transmit four signals (i.e., four-lane MIPI). The signal transmission interface is the MIPI interface. Thus, the processor can use the two MIPI ports to output a total of eight signals.

[0115] In application, each display screen 120 can be alternately and cyclically connected to a MIPI interface via the signal conversion unit 130, such as... Figure 7 As shown, the other MIPI interface of display screen 120 is idle. During signal transmission, the MIPI signals of the two display screens 120 are transmitted in a time-division manner based on the connectivity between display screen 120 and processor 110, and the two display screens 120 light up alternately in a time-division manner, thereby reducing the instantaneous peak power consumption of the system, reducing the power load, and improving the overall stability of the system.

[0116] In some embodiments, both signal transmission interfaces 100 of the display screen 120 can be used for signal transmission to improve the signal transmission rate, shorten the signal transmission time, and improve the overall display effect, as detailed below.

[0117] In some embodiments, Figure 9 In response to Figure 8 The diagram shows a display driving timing diagram of a display system. (Combined with...) Figure 8 and Figure 9 Within an alternating cycle, for each display screen 120, the duration includes both signal transmission duration and screen illumination duration, with the screen illumination duration following the signal transmission duration.

[0118] The duration of an alternating cycle includes the alternating cycle duration of signal transmission across all display screens in the display system, as well as the alternating cycle duration of screen illumination across all display screens in the display system.

[0119] For a single display screen 120, there is a signal transmission duration and a screen lighting duration in an alternating cycle; wherein, the signal transmission duration corresponds to the duration during which the display screen 120 is connected to the processor 110.

[0120] In this embodiment of the disclosure, the screen lighting duration is set after the signal transmission duration, that is, the start time of screen lighting is after the end time of signal transmission. This enables the backlight module in the display screen 120 to be lit only after the signal corresponding to the display screen 120 has been fully transmitted and the liquid crystal has been fully deflected, thereby avoiding the trailing phenomenon. While reducing instantaneous peak power consumption and improving the overall stability of the system, it can also achieve a better display effect.

[0121] In some embodiments, continue to refer to Figure 8 and Figure 9 Among the display screens 120 that are connected to the processor 110 in adjacent time intervals, the screen lighting duration of the display screen 120 that is connected to the processor 110 first is within the signal transmission duration of the display screen 120 that is connected to the processor 110 later.

[0122] Specifically, for each display screen 120, when switching to the processor 110 to connect to the next / next group of display screens 120, during the signal transmission process of the next / next group of display screens 120, after the signal transmission of that display screen 120 is completed and the liquid crystal is fully deflected, the backlight module of that display module 120 is lit up. Thus, while other display screens 120 are transmitting signals, the backlight of the display screen 120 that has completed signal transmission is lit up. On the one hand, this shortens the display response time and improves the response speed; on the other hand, it saves the switching time between different display screens, allowing the images presented by different display screens 120 to appear within a time imperceptible to the observer's eyes, avoiding image separation and improving the display effect.

[0123] For example, in combination Figure 8 and Figure 9 Data1 represents data on the first display screen 121, and Data2 represents data on the second display screen 122. The processor 110 sequentially and alternately outputs Data1 from the first display screen 121 and Data2 from the second display screen 122. Correspondingly, through the switching of the signal conversion unit 130, the first display screen 121 and the second display screen 122 sequentially and alternately receive the corresponding data. Furthermore, after the first display screen 121 receives data, the first display screen 121 lights up when the second display screen 122 receives data; simultaneously, after the second display screen 122 receives data, the second display screen 122 lights up when the first display screen 121 receives data, thereby realizing time-division multiplexing of data transmission and screen lighting, thereby reducing instantaneous power consumption peaks and improving the overall stability of the system.

[0124] In some embodiments, when at least two display screens 120 are divided into at least two groups, the signal transmission duration of the display screens 120 in the same group is the same; the lighting duration of each screen of the display screens 120 in the same group is staggered and falls within the signal transmission duration of the next group of display screens 120.

[0125] In this case, the signal transmission duration of the display screens 120 in the same group is the same, that is, the display screens 120 in the same group are simultaneously connected to the processor 110 by the signal conversion unit 130, and the start time and end time of their signal transmission duration are the same, that is, the display screens 120 in the same group transmit signals at the same time; thus, when the number of display screens 120 in a group is at least two, the signal transmission time can be saved.

[0126] Meanwhile, by setting the lighting duration of each screen 120 within the same group to be staggered sequentially, the screens 120 within the same group can be set to light up at different times, which helps to further reduce system power consumption. Furthermore, by limiting the lighting duration of each screen 120 in this group to within the signal transmission duration of the next group of screens 120, the lighting of the current group's screens can be prevented from affecting the lighting of the next group's screens, and the lighting duration of this group can be prevented from affecting the lighting duration of the next group of screens 120, thereby avoiding display disorder and ensuring a better display effect.

[0127] In some embodiments, continue to refer to Figure 8 and Figure 9 At least two display screens 120 include a first display screen 121 and a second display screen 122; the signal conversion unit 130 is used to alternately and cyclically connect the first display screen 121 and the second display screen 122 to the processor 110 respectively; correspondingly, the first display screen 121 and the second display screen 122 are lit up alternately and cyclically.

[0128] This setup can be applied to scenarios such as virtual reality to achieve multi-directional stereoscopic display.

[0129] In this embodiment of the disclosure, by setting the signal conversion unit 130, the signals of the first display screen 121 and the second display screen 122 can be transmitted in a time-division manner. For example, the transmission of MIPI data of the two display screens 120 can be carried out alternately. At the same time, the lighting duration of the backlight modules of the two display screens 120 is also staggered, thereby halving the peak power consumption of the display system 10, thereby reducing the system power load and improving system stability.

[0130] In some embodiments, continue to refer to Figure 8 and Figure 9 The first display screen 121 lights up after switching to the second display screen 122, and the second display screen 122 lights up after switching to the first display screen 121.

[0131] In this configuration, the signal conversion unit 130 switches from connecting the processor 110 and the first display screen 121 to connecting the processor 110 and the second display screen 122, indicating that the first display screen 121 has completed the signal transmission within the current cycle. Afterward, the second display screen 122 connects to the processor 110 to begin signal transmission, and the first display screen 121 lights up. Similarly, the signal conversion unit 130 switches from connecting the processor 110 and the second display screen 122 to connecting the processor 110 and the first display screen 121, indicating that the second display screen 122 has completed the signal transmission within the current cycle. Afterward, the first display screen 121 connects to the processor 110 again to begin signal transmission, and the second display screen 122 lights up.

[0132] This enables the first display screen 121 and the second display screen 122 to transmit signals alternately and light up in a time-division manner, thereby reducing the peak instantaneous power consumption and improving system stability.

[0133] In some embodiments, continue to refer to Figure 8 and Figure 9 The signal conversion unit 130 has at least two output terminals 132, including a first output terminal 1321 and a second output terminal 1322; a first display screen 121 is connected to the first output terminal 1321, and a second display screen 122 is connected to the second output terminal 1322; the input terminal 131 of the signal conversion unit 130 is alternately and cyclically connected to the first output terminal 1321 and the second output terminal 1322.

[0134] With this configuration, the input terminal 131 inside the signal conversion unit 130 is alternately and cyclically connected between the first output terminal 1321 and the second output terminal 1322, enabling the first display screen 121 and the second display screen 122 to be alternately and cyclically connected to the processor. This allows the first display screen 121 and the second display screen 122 to transmit signals in a time-division manner and to light up at different times. Furthermore, the switching method of the signal conversion unit 130 is simple and convenient.

[0135] In some embodiments, continue to refer to Figure 8 and Figure 9 The signal conversion unit 130 includes a double-pole double-throw switch; the stationary contact of the double-pole double-throw switch is the input terminal 131 of the signal conversion unit 130, and the two moving contacts of the double-pole double-throw switch are the first output terminal 1321 and the second output terminal 1322 of the signal conversion unit 130, respectively.

[0136] With this configuration, by switching between the two moving contacts using a double-pole double-throw switch, the input terminal 131 of the signal conversion unit 130 is alternately and cyclically connected to the first output terminal 1321 and the second output terminal 1322. This allows the first display screen 121 and the second display screen 122 to alternately and cyclically connect to the processor. The first display screen 121 and the second display screen 122 transmit signals in a time-sharing manner and light up at staggered times. Furthermore, the signal conversion unit 130 has a simple circuit structure, low cost, and a simple and convenient switching method.

[0137] In conjunction with the above, in this embodiment of the disclosure, the two MIPI interfaces of the processor 110 are connected to the two MIPI interfaces of the signal conversion unit 130, and the two MIPI interfaces of each of the two output terminals of the signal conversion unit 130 are respectively connected to the two display screens 120. Thus, the MIPI signal is transmitted sequentially to the two display screens 120 through the two MIPI interfaces in a time-division manner. After the transmission is complete, the backlight module of the display screen 120 is illuminated, thereby realizing time-division signal transmission and time-division backlight module illumination, reducing power consumption and improving system stability.

[0138] Meanwhile, compared to the structures in related technologies, the signal transmission rate is doubled in this embodiment of the disclosure. While realizing time-division transmission of signals, it ensures that the signal transmission time is not increased, thereby not increasing the display response time, and ensuring a faster response speed and better display effect.

[0139] For example, in combination Figure 9 For a single display screen 120, the transmission time of the MIPI signal is approximately 5ms to 6ms, and the illumination time of the backlight module is approximately 1ms; for two display screens 120, the duration of a complete cycle is approximately 10.1ms.

[0140] In other implementations, the duration of each stage can be set according to other durations, which will not be elaborated or limited here.

[0141] This disclosure also provides a display control method for any of the above-described display systems, which has corresponding beneficial effects.

[0142] In some embodiments, Figure 10 This is a schematic flowchart illustrating a display control method provided in an embodiment of this disclosure. (Refer to...) Figure 10 The method includes the following steps.

[0143] S301. Obtain the conversion control signal corresponding to the signal conversion unit.

[0144] The conversion control signal is used to control the circuit connection relationship inside the signal conversion unit, so as to realize the connection between the input end of the signal conversion unit and the corresponding output end, and then connect the processor and the corresponding display screen.

[0145] The acquisition of conversion control signals can be achieved by the processor calling stored, preset, automatically generated, or user-input conversion control signals, and is not limited here.

[0146] S302, based on the conversion control signal and the signal conversion unit, alternately and cyclically connects each of the at least two display screens to the processor.

[0147] The number of display screens that connect to the processor at a single time is less than the total number of display screens.

[0148] Among them, the conversion control signal can control the display screen used to realize the display function to not connect all the processors at once, but connect the processors in batches and alternately in a cyclical manner, so as to transmit signals in batches and alternately in a cyclical manner.

[0149] S303, alternately and cyclically illuminate each display screen.

[0150] In this process, each display screen is lit sequentially according to the alternating cyclical sequence of its connection to the processor, thereby achieving time-sharing lighting of the display screens.

[0151] In the above embodiments, the control signal for lighting up the screen can be generated based on the action of ending signal transmission, or it can be obtained directly, which will be explained below.

[0152] In some embodiments, Figure 10 Based on this, S303 may specifically include:

[0153] For each display screen:

[0154] After the display screen connected to the processor is switched, a screen-on control signal is generated for that display screen.

[0155] The display screen is turned on based on the screen-on control signal.

[0156] The signal used to light up the screen can be a screen-light control signal generated upon the end of signal transmission. Specifically, after the processor switches to a different display screen, that is, after the signal transmission to that display screen ends, a screen-light control signal is generated for that display screen. This signal illuminates the backlight module of the display screen after all the liquid crystals in the screen have deflected, thus enabling display.

[0157] In summary, since the display screen is connected to the processor in a time-sharing manner, the signal is transmitted in a time-sharing manner. As a result, the generated screen-on control signal can control the display screen to light up in a time-sharing manner, thereby reducing the instantaneous power consumption peak of the display system, reducing the system power load, and improving the overall stability of the system.

[0158] In some embodiments, when the display screen is connected to the processor, the method further includes:

[0159] Obtain the display control signal.

[0160] The display control signal is used to control the display screen to turn on. For example, the display control signal can be acquired by the processor and used to control the display screen to perform the operation; or the display control signal can be transmitted from the processor to the display screen, that is, acquired by the display screen and used to perform the corresponding lighting action.

[0161] Based on this, Figure 10 Based on this, S303 may specifically include:

[0162] Based on the display control signal, each display screen is lit up alternately and cyclically.

[0163] Specifically, the display screen can be lit up alternately and cyclically based on the display control signal, thereby realizing the time-sharing lighting of the display screen.

[0164] It is understandable that the display control signal and the switching control signal satisfy the time sequence and duration relationship mentioned above, so as to coordinate the time-division transmission of signals and the time-division appearance of backlights, and realize the coordinated display of each display screen.

[0165] In some embodiments, Figure 10 Based on this, S303 may specifically include:

[0166] The backlight modules of each display screen are alternately and cyclically illuminated.

[0167] When the display screen is an LCD screen, it includes a backlight module, also known as a backlight source. Therefore, when the display screen lights up, the backlight source of the display screen is also illuminated.

[0168] In other embodiments, the display screen may also be other types of display screens that achieve display based on a backlight, which are not limited here.

[0169] In some embodiments, within an alternating cycle, the duration for each display screen includes both signal transmission duration and screen illumination duration.

[0170] Among display screens that are connected to the processor at adjacent times, the screen illumination duration of the display screen that connects to the processor first is within the signal transmission duration of the display screen that connects to the processor later.

[0171] This configuration allows the backlight module of the current display screen to be lit while the signal is being transmitted to the next display screen, saving time and ensuring a faster display response speed and better display effect.

[0172] This disclosure also provides a display control device for executing any of the display control methods described in the above embodiments, which has corresponding beneficial effects.

[0174] The first acquisition module 410 is used to acquire the conversion control signal corresponding to the signal conversion unit;

[0175] The first control module 420 is used to alternately and cyclically connect each of the at least two display screens to the processor based on the conversion control signal and the signal conversion unit;

[0176] The second control module 430 is used to alternately and cyclically light up each display screen;

[0177] The number of display screens that connect to the processor at a single time is less than the total number of display screens.

[0178] In some embodiments, the second control module 430 is used to alternately and cyclically illuminate each display screen, specifically including:

[0179] For each display screen:

[0180] After the display screen connected to the processor is switched, a screen-on control signal is generated for that display screen.

[0181] The display screen is turned on based on the screen-on control signal.

[0182] In some embodiments, continue to refer to Figure 11 The display control device 40 may further include:

[0183] The second acquisition module 440 is used to acquire display control signals when the display screen is connected to the processor.

[0184] Based on this, the second control module 430 is used to alternately and cyclically light up each display screen, specifically including:

[0185] Based on the display control signal, each display screen is lit up alternately and cyclically.

[0186] In some embodiments, the second control module 430 is used to alternately and cyclically illuminate each display screen, specifically including:

[0187] The backlight modules of each display screen are alternately and cyclically illuminated.

[0188] In some embodiments, within an alternating cycle, the duration for each display screen includes both signal transmission duration and screen illumination duration.

[0189] Among display screens that are connected to the processor at adjacent times, the screen illumination duration of the display screen that connects to the processor first is within the signal transmission duration of the display screen that connects to the processor later.

[0213] This disclosure also provides a wearable display device, which includes any of the display systems described in the above embodiments, and / or uses any of the display control methods described in the above embodiments to achieve the display, and has corresponding beneficial effects.

[0214] In some embodiments, the wearable display device includes at least one of a helmet-mounted display device, virtual reality glasses, augmented reality glasses, and mixed reality glasses.

[0215] For example, virtual reality (VR) glasses are a type of computer simulation device that can create and experience virtual worlds. They can use computer programs to generate a simulated environment, providing a multi-source information fusion, interactive three-dimensional dynamic visual scene and entity behavior simulation, allowing users to immerse themselves in the virtual environment.
