Description

Display system, method, device, medium, apparatus, product, and display device

Technical Field

The disclosure relates to the technical field of display, and in particular relates to a display system, a method, a device, a medium, equipment, a product and a display device.

Background

With the development of display technology, the liquid crystal display technology is mature and gradually applied to scenes such as virtual reality, augmented reality, mixed reality and the like, so as to provide pictures of the virtual world. Generally, a liquid crystal display screen is composed of a backlight module, a lower polarizer, a circuit substrate, a liquid crystal layer, a color filter and an upper polarizer; wherein, the electric field is applied through the circuit substrate to control the deflection angle of the liquid crystal in the liquid crystal layer so as to realize the modulation of the light transmission intensity.

In general, since the liquid crystal is deflected for a certain period of time, if the backlight module is turned on without completely deflecting the liquid crystal, a smear, i.e., a smear phenomenon, is generated. Currently, in order to reduce the tailing phenomenon in the liquid crystal display, black insertion is performed. Specifically, the backlight module is turned off during data transmission and liquid crystal deflection; after the data transmission is completed, the backlight module is lightened after the liquid crystal deflection is completed. However, when the display system includes a plurality of display screens, for example, the display screens for the left eye and the right eye need to be set in the above scene, the problem of excessively high instantaneous power consumption of the system easily occurs, which further results in a larger power load and poor stability of the system.

Compared with the related art, the system can avoid the problems of higher power consumption and poor system stability caused by the simultaneous data transmission and simultaneous lighting of all display screens.

The display system, the display control method for the system, the display control device, the storage medium, the electronic device, the computer program product and the wearable display device are described below with reference to specific embodiments, and the beneficial effects of the technical solution provided by the embodiments of the disclosure are described based on comparison with the related art.

First, a related art scheme will be described with reference to fig. 1 and 2.

Fig. 1 is a schematic structural diagram of a display system in the related art, and fig. 2 is a schematic structural diagram of a display driving timing diagram in the related art. Referring to fig. 1 and 2, in the related art, a 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 and the system main processor 011 are connected by a signal path, the second display screen 013 and the system main processor 011 are connected by another signal path, and the first display screen 012 and the second display screen 013 each comprise a standby signal path. Based on the above, during data transmission, MIPI signals of two screens are transmitted simultaneously, namely, the data transmission process is started simultaneously and ended simultaneously; and, the backlight modules of the two display screens are turned on simultaneously, as shown in fig. 2, so that the power consumption of the display system is high instantaneously, the power load of the display system is high, and the system is unstable.

In view of this, the embodiment of the disclosure proposes to transmit the MIPI signal in a time-sharing manner, and the backlight module of the display screen is turned on in a time-sharing staggered manner, so as to reduce the instant power consumption of the display system, reduce the power load, and improve the system stability.

The following description refers to the accompanying drawings.

In some embodiments, fig. 3 is a schematic structural diagram of a display system according to an embodiment of the disclosure, and fig. 4 is a schematic display driving timing diagram of the display system shown in fig. 3. Referring to fig. 3 and 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 end 131 and at least two output ends 132, the input end 131 is connected with the processor 110, and the at least two output ends 132 are connected with the at least two display screens 120 in a one-to-one correspondence; the signal conversion unit 130 is configured to alternately and cyclically communicate each display screen 120 of the at least two display screens 120 with the processor 110; correspondingly, each display screen 120 alternately and cyclically lights up; wherein the number of display screens 120 in single communication with the processor 110 is less than the total number of display screens.

The processor 110 is a main processor of the display system, and is used for controlling other components in the display system, such as the signal conversion unit 130 and the display screen 120 to cooperate to enable the display system to meet display requirements. For example, the processor 110 may output a mobile industry processor interface (Mobile Industry Processor Interface, MIPI) signal, and time-sharing data (i.e., signals) is time-sharing MIPI signal.

Wherein, the number of the display screens 120 may be represented by N, and the number of the display screens 120 that are connected and lighted at a time may be represented by M; wherein N is more than or equal to 2, M is more than or equal to 1 and less than N, and M and N are integers. Thus, the number of display screens 120 is at least two, for example, two, three or more, i.e., N may have a value of 2, 3, 4 or more; correspondingly, the number of the display screens 120 that are connected and lighted once, i.e. the value of M, may be 1, 2 or other values satisfying M < N, which is not limited herein. Thus, the double-screen or multi-screen collaborative display is realized.

The display screen 120 may be a liquid crystal display screen, which includes a backlight module; in the disclosed embodiment, the display screen 120 is lit up corresponding to the backlight module being lit up.

The input end 131 of the signal conversion unit 130 is connected to the processor 110, and the output ends 132 are respectively connected to the display screen 120 in a one-to-one correspondence. Based on this, the signal conversion unit 130 can realize that the display screen 120 is alternately circulated in batch to communicate with the processor 110 by switching the output terminal 132, which is in communication with the input terminal 131, in batch; and, the display modules 120 are alternately and circularly lighted, so that the display modules 120 are lighted in batches and in time, and the problem of excessively high instantaneous power consumption caused by simultaneous lighting of all the display modules 120 in the display system 10 is avoided. Therefore, the signal conversion unit 130 is used to realize the communication relationship switching between the display screen 120 and the processor 110, so that the number of display modules 120 for simultaneously transmitting data can be reduced, the number of display modules 120 which are simultaneously lightened can be reduced, the instant power consumption in the display process of the display system 10 can be reduced, the load of a system power supply can be reduced, and the overall stability of the system can be improved.

Illustratively, as shown in fig. 4, among the bright screen control signals V11, V12, and V13 of the respective display screens, a high level signal represents that the display screen is bright. Referring to fig. 3 and 4, when the display system 10 includes a plurality of display screens 120, each display screen 120 is sequentially and alternately and circularly connected to the processor through the signal conversion unit 130, and sequentially and alternately and circularly lighted, thereby, compared with the case that all display screens are simultaneously lighted, the maximum value of the instantaneous power consumption can be reduced to 1/N of that in the related art, thereby reducing the instantaneous power consumption of the display system and improving the system stability.

Fig. 5 is a schematic structural diagram of another display system according to an embodiment of the disclosure, and fig. 6 is a schematic display driving timing diagram of the display system shown in fig. 5. Referring to fig. 5 and 6, in the display system 10, the number N of the display screens 120 may be specifically 2, and the display screens 120 may include a first display screen 121 and a second display screen 122; and the first display screen 121 and the second display screen 122 are sequentially and alternately connected to the processor 110 by the switching of the signal conversion unit 130, and the first display screen 121 and the second display screen 122 are sequentially and alternately lighted. Therefore, in the embodiment of the disclosure, compared with the case that all display screens are simultaneously lightened, the maximum value of the instant power consumption can be reduced by 1/2, so that the instant power consumption of a display system is reduced, and the system stability is improved.

In the display system 10 provided in the embodiment of the present disclosure, by setting the signal conversion unit 130, each display screen 120 in the display system 10 is communicated to the processor 110 in a time-sharing manner, so that the time-sharing transmission of signals corresponding to the display screens 120 can be realized, that is, the signals corresponding to the plurality of display screens 120 are transmitted according to the communication sequence of the display screens 120, and are not transmitted at the same time; meanwhile, the time for lighting the backlight module of the display screen 120 is also staggered, that is, the display screen 120 (i.e., the backlight module therein) is lighted in a time-sharing manner, so that the power consumption peak value of the display system 10 is reduced, the power load of the display system 10 is reduced, and the overall stability of the system is improved.

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

Wherein, by grouping the display screens 120, the same group of display screens 120 can be simultaneously connected to the processor 110 by the signal conversion unit 130 to realize corresponding signal transmission; further, the display screens 120 of the same group may be simultaneously lit, i.e., the lighting start times and the lighting end times of the display screens of the same group are the same.

Meanwhile, the signal conversion unit 130 is utilized to alternately and circularly connect the different groups of display modules 120 to the processor 110, i.e. alternately and circularly transmit signals, and alternately and circularly light up; thus, while reducing the display screen 120 for simultaneously transmitting data and the display screen 120 for simultaneously lighting, the structural regularity of the signal conversion unit 130 is strong, and the control manner is flexible and convenient.

For example, when N has a value of 2, the display screens 120 may be divided into two groups, and the number of display screens 120 in each group is 1, in conjunction with fig. 5.

For example, when N has a value of 3, referring to fig. 3, the display screens 120 may be divided into two groups, one group having 1 number of display screens 120 and the other group having 2 number of display screens 120. Alternatively, when N has a value of 3, the display screens 120 may be divided into three groups, and the number of display screens 120 in each group is 1.

In other embodiments, when N has a value of 4, 5 or more, the display screens 120 may be divided into 2, 3 or more groups, and the number of display screens 120 in each group is at least one, and the number of display modules 120 in each group may be the same or different, which is not limited herein.

In some embodiments, if at least two display modules 120 are equally divided into N 'groups, and each group of display modules 120 is alternately and cyclically connected to the processor 110 by switching of the signal conversion unit 130, and is correspondingly alternately and cyclically turned on, the instantaneous power consumption peak of the display system 10 is reduced to 1/N', which is not exemplified.

Referring to fig. 7 and 8, the number of signal transmission interfaces 100 of the input end 131 of the signal conversion unit 130 is equal to or greater than the number of signal transmission interfaces 100 of the signal output end of the processor 110, the number of signal transmission interfaces 100 of each output end 132 of the signal conversion unit 130 is equal to or greater than the number of signal transmission interfaces 100 of the signal input end of the display screen 120 connected to the output end 132, and the number of signal transmission interfaces 100 of the signal output end of the processor 110 is equal to or greater than the number of signal transmission interfaces 100 of the signal input end of the single display screen 120.

The number P2 of the signal transmission interfaces 100 at the signal input end of the display screen 120 may be 1, 2 or more, and may be set based on the signal transmission requirement, which is not limited herein.

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

Illustratively, when p2=1, P1 may be 1, 2, 3 or greater; when p2=2, P1 may be 2, 3, 4 or more, and is not limited herein.

The number of signal transmission interfaces 100 at each output end of the signal conversion unit 130 is P4; the number P3 of the signal transmission interfaces 100 at the input end of the signal conversion unit 130 is equal to the number P4 of the signal transmission interfaces 100 at the single output end of the signal conversion unit 130, so as to meet the signal transfer requirement; further, the number P3 of the signal transmission interfaces 100 at the input end of the signal conversion unit 130 is equal to or greater than the number P1 of the signal transmission interfaces 100 at the signal output end of the processor 110 to meet the signal input requirement, and the number P4 of the signal transmission interfaces 100 at the output end of the signal conversion unit 130 is equal to or greater than the number P2 of the signal transmission interfaces 100 at the signal input end of the display screen 120 to meet the signal output requirement, so that the signal transfer between the processor 110 and the display screen 120 can be realized by using the signal conversion unit 130.

Illustratively, when p2=1, both P3 and P4 can be 1, 2, 3 or greater; when p2=2, P3 and P4 may each be 2, 3, 4 or more, and are not limited herein.

In other embodiments, the number of signal transmission interfaces of the input/output terminals can be flexibly set to meet the requirements of signal switching and structure expansion, which is not limited herein.

In some embodiments, the number of signal transmission interfaces 100 satisfies: 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 the single display screen 120 are all equal, that is, p4=p3=p2=p1.

Alternatively, p4=p3=p2=p1=2.

So set up to satisfy virtual reality's application demand.

In some embodiments, each signal transmission interface 100 is used to transmit 4-way signals.

The device is arranged in such a way to meet the application requirements of virtual reality, simultaneously meet the signal transmission rate requirements, realize high-speed signal transmission and further meet the display response speed requirements.

For example, in conjunction with fig. 7 and 8, in the display system 10 applied in the virtual reality scenario, the processor typically has a 2-interface (port) MIPI, and 2 display screens 120 are provided, each display screen has 2-interface MIPI, each interface can transmit 4-way signals (i.e., 4lanes MIPI), and the signal transmission interface is the MIPI interface. Thus, the processor can output 8 paths of signals by using 2 MIPI interfaces.

In application, each display screen 120 may alternately and cyclically connect one MIPI interface through the signal conversion unit 130, as shown in fig. 7, and the other MIPI interface of the display screen 120 is idle. During signal transmission, the MIPI signals of the two display screens 120 are transmitted in a time-sharing mode based on the communication relation between the display screens 120 and the processor 110, and the two display screens 120 are alternately lightened in a time-sharing mode in sequence, so that instantaneous peak power consumption of the system is reduced, power load is reduced, and the overall stability of the system is improved.

In some embodiments, the signal transmission can be performed by using both signal transmission interfaces 100 of the display screen 120, so as to increase the signal transmission rate, shorten the signal transmission time, and improve the overall display effect, which will be described in detail later.

In some embodiments, fig. 9 is a display driving timing diagram for the display system shown in fig. 8. Referring to fig. 8 and 9, in a period of one alternate cycle, the period includes a signal transmission period and a screen lighting period for each display screen 120, and the screen lighting period is located after the signal transmission period.

The time length of one alternating cycle comprises the time length of the alternating cycle of signal transmission of all display screens in the display system and the time length of the alternating cycle of screen lighting of all display screens in the display system.

For a single display screen 120, there is one signaling duration and one screen lighting duration in one alternating cycle; wherein the signal transmission duration corresponds to the duration that the display screen 120 is in communication with the processor 110.

In the embodiment of the disclosure, the set screen lighting time is located after the signal transmission time, that is, the start time of screen lighting is located after the end time of signal transmission, so that the backlight module in the display screen 120 can be lightened after the signal corresponding to the display screen 120 is completely transmitted and the liquid crystal is completely deflected, thereby avoiding the tailing phenomenon, reducing the instantaneous peak power consumption, improving the overall stability of the system and simultaneously realizing better display effect.

In some embodiments, with continued reference to fig. 8 and 9, in the display screen 120 that is in communication with the processor 110 that is temporally adjacent, the screen-on duration of the display screen 120 of the preceding communication processor 110 is within the signal transmission duration of the display screen 120 of the following communication processor 110.

Wherein, for each display screen 120, when switching to the processor 110 to communicate with the next/next group of display screens 120, the backlight module of the display module 120 is turned on after the liquid crystal is completely deflected after the signal transmission of the display screen 120 is completed in the signal transmission process of the next/next group of display screens 120. Thus, the backlight of the display screen 120 with the signal transmission completed is lightened while the signal transmission is performed on other display screens 120, so that on one hand, the display response time is shortened, and the response speed is improved; on the other hand, the time for switching between different display screens is saved, the pictures presented by different display screens 120 are presented in the time which cannot be resolved by the glasses of the observer, the separation of the display pictures is avoided, and the display effect is improved.

Illustratively, in connection with fig. 8 and 9, data1 represents Data of the first display screen 121, and Data2 represents Data of the second display screen 122; the processor 110 sequentially and alternately outputs the Data1 of the first display screen 121 and the Data2 of the second display screen 122; correspondingly, the first display screen 121 and the second display screen 122 alternately receive the corresponding data in sequence by the switching of the signal conversion unit 130; further, after the first display screen 121 receives data, the first display screen 121 is lit up when the second display screen 122 receives data; meanwhile, after the second display screen 122 receives the data, when the first display screen 121 receives the data, the second display screen 122 is turned on, so that the time-sharing data transmission and the screen lighting are realized, the instantaneous power consumption peak value is reduced, and the overall stability of the system is improved.

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 durations of the display screens 120 in the same group are staggered in turn and are located within the signal transmission duration of the next group of display screens 120.

The signal transmission time periods of the display screens 120 in the same group are the same, that is, the display screens 120 in the same group are all simultaneously connected to the processor 110 by the signal conversion unit 130, the start time and the end time of the signal transmission time periods are the same, that is, the display screens 120 in the same group simultaneously transmit signals; thus, when the number of display screens 120 in a group is at least two, signal transmission time can be saved.

Meanwhile, by arranging the lighting time lengths of the display screens 120 in the same group to be staggered in sequence, the display screens 120 in the same group can be lightened at different time, which is beneficial to further reducing the system power consumption; and, by limiting the duration of each screen of the display screen 120 of the present group to the duration of signal transmission of the next display screen 120, the influence of the screen of the present group on the screen of the next group can be avoided, and the influence of the present group on the duration of the next display screen 120 is avoided, thereby avoiding display disorder and ensuring better display effect.

In some embodiments, with continued reference to fig. 8 and 9, the 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 communicate the first display screen 121 and the second display screen 122 with the processor 110, respectively; correspondingly, the first display screen 121 and the second display screen 122 alternately and cyclically light up.

The multi-direction stereoscopic display device can be applied to scenes such as virtual reality and the like, and multi-direction stereoscopic display is achieved.

In the embodiment of the present disclosure, by providing 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-sharing manner, for example, the transmission of MIPI data of the two display screens 120 is performed alternately in tandem; meanwhile, the lighting time periods of the backlight modules of the two display screens 120 are staggered, so that the peak power consumption of the display system 10 can be halved, the system power load is reduced, and the system stability is improved.

In some embodiments, with continued reference to fig. 8 and 9, the moment of brightness of the first display screen 121 is after the transition to communicate with the second display screen 122, and the moment of brightness of the second display screen 122 is after the transition to communicate with the first display screen 121.

The signal conversion unit 130 is converted from the communication processor 110 and the first display screen 121 to the communication processor 110 and the second display screen 122, which indicates that the first display screen 121 completes signal transmission in the current cycle, after that, the second display screen 122 is communicated to the processor 110 to start signal transmission, and the first display screen 121 is turned on; similarly, the signal conversion unit 130 is converted from the communication processor 110 and the second display screen 122 to the communication processor 110 and the first display screen 121, which indicates that the second display screen 122 completes the signal transmission in the current cycle, after which the first display screen 121 is again connected to the processor 110 to start the signal transmission, and the second display screen 122 is turned on.

Thus, the first display screen 121 and the second display screen 122 alternately transmit signals in a time-sharing manner, and are lighted in a time-sharing manner, so that instantaneous power consumption peaks are reduced, and system stability is improved.

In some embodiments, with continued reference to fig. 8 and 9, at least two outputs 132 of the signal conversion unit 130 include a first output 1321 and a second output 1322; the first display screen 121 is connected to the first output end 1321, and the second display screen 122 is connected to the second output end 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.

So configured, the first display screen 121 and the second display screen 122 are alternately and cyclically connected to the processor through the input terminal 131 inside the signal conversion unit 130 alternately and cyclically connected between the first output terminal 1321 and the second output terminal 1322, thereby realizing time-sharing transmission signals of the first display screen 121 and the second display screen 122, and time-sharing staggered lighting. Meanwhile, the switching mode of the signal conversion unit 130 is simple and convenient.

In some embodiments, with continued reference to fig. 8 and 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 end 131 of the signal conversion unit 130, and the two movable contacts of the double pole double throw switch are the first output end 1321 and the second output end 1322 of the signal conversion unit 130 respectively.

So configured, by switching the double pole double throw switch between the two movable contacts, the input end 131 of the signal conversion unit 130 is alternately and cyclically connected to the first output end 1321 and the second output end 1322, so that the first display screen 121 and the second display screen 122 are alternately and cyclically connected to the processor, the first display screen 121 and the second display screen 122 transmit signals in a time sharing manner, and the time sharing is staggered and turned on. Meanwhile, the circuit structure of the signal conversion unit 130 is simple, the cost is low, and the switching mode is simple and convenient.

In combination with the above, in the embodiment of the present disclosure, the 2 MIPI interfaces of the processor 110 are connected to the two MIPI interfaces of the signal conversion unit 130, and the 2 MIPI interfaces of each of the 2 output ends of the signal conversion unit 130 are respectively connected to the 2 display screens 120. Therefore, the MIPI signals sequentially pass through the 2 MIPI interfaces, signals are respectively transmitted to the 2 display screens 120 in a time-sharing mode, and the backlight module of the display screen 120 is lightened after the transmission is completed, so that the time-sharing transmission of the signals and the time-sharing lighting of the backlight module are realized, the power consumption is reduced, and the system stability is improved.

Meanwhile, compared with the structure in the related art, the signal transmission rate is doubled in the embodiment of the disclosure, and the signal transmission time is ensured not to be increased while the time-sharing transmission of the signal is realized, so that the display response time is not increased, and the faster response speed and the better display effect are ensured.

For example, referring to fig. 9, for one display screen 120, the transmission time of the mipi signal is about 5ms to 6ms, and the lighting duration of the backlight module is about 1ms; the duration of one complete cycle for both display screens 120 is about 10.1ms.
