Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In the prior art, in order to reduce delay and smear generated by display of a VR device, a method of replacing a display screen is generally adopted, and a fast-response liquid crystal screen or an O L ED screen with fast response time and high refresh rate is used in the VR device.
However, the color gamut of the fast response liquid crystal screen is small and expensive, and the current O L ED screen has limited production capacity, short supply and high cost.
Based on this, consider that the odd-even refresh mechanism through current screen cooperates the polaroid, can reduce the display smear of screen, and under the condition that does not increase VR system burden and components and parts cost, improve user experience, practice thrift the cost simultaneously.
In view of the above, in order to solve the problem of high cost of the VR device in the prior art, the present invention provides a screen display method, in which a terminal converts light emitted from a specific line in a screen into polarized light and stops light emitted from the remaining lines except the specific line in the screen, wherein the specific line includes an odd line or an even line, the terminal may obtain a first signal or a second signal transmitted from the screen, wherein the first signal is a first synchronization signal transmitted when refreshing of the specific line of the screen starts, and the second signal is a second synchronization signal transmitted when refreshing of the specific line of the screen is completed, the terminal stops transmitting the polarized light when obtaining the first signal so that the polarized light cannot enter both eyes, and when obtaining the second signal, the terminal transmits the polarized light to display when judging that liquid crystal in the screen is completely turned, so that both eyes of a user can receive the polarized light, because only the odd line or the even line, although the resolution of an image viewed by both eyes of the user loses half, the image viewed by both eyes of the user is displayed, and the VR device can reduce the cost of the displayed image L when the screen is turned over, thereby saving the screen display cost of the VR device.
It should be noted that the screen display method provided by the embodiment of the present invention is preferably applied to a VR device. In the following, the terminal is taken as an example of a VR device.
Referring to fig. 1, fig. 1 is a schematic flowchart of a screen display method according to an embodiment of the present invention, which may include the following steps:
s110, converting light rays emitted by a specific line in a screen into polarized light rays by a terminal, and stopping emitting the light rays by other lines except the specific line in the screen; wherein the particular row comprises: odd or even rows;
specifically, in an implementation mode, the polaroid can be customized according to the size of the screen, the customized polaroid is attached to the screen, and the final effect is that the light emitted by the screen is polarized into polarized light, so that the realization: the light emitted from a particular line in the screen is converted to polarized light. For example, if the size of the screen is a × b (length is a, width is b), a polarizing plate having the same size as a × b may be fabricated, and the fabricated polarizing plate may be attached to the screen, and the polarization direction of the polarizing plate may be set to a vertical or horizontal direction, so that the light emitted from the screen may be polarized into a polarized light having a vibration direction in the vertical or horizontal direction. Any other customization method capable of implementing the polarizer belongs to the protection scope of the embodiment of the present invention, and is not repeated herein.
Wherein, the screen can be a liquid crystal screen supporting odd-even refreshing. The odd-even refreshing is a refreshing mechanism of a screen, and specifically means that odd rows are refreshed first and even rows are refreshed later in the refreshing process of the screen.
In practical application, although the screen supports odd-even refresh, the existing screen driving technology can be utilized, so that the screen refreshes only a specific row of the screen in the refreshing process, and the following effects are achieved: and stopping emitting light to the other lines except the specific line in the screen. For example, only the odd rows (or even rows) of the screen are refreshed, the even rows (or odd rows) are not refreshed, namely, the even rows (or odd rows) do not emit light and only display black, so that the refreshing time is shortened, and the smear is reduced.
It should be noted that, the present application is only described above as an example, and the implementation manner of converting the light emitted from a specific line in the screen into polarized light in practical application is not limited to this.
S120, the terminal obtains a first signal or a second signal sent by a screen, wherein the first signal is a first synchronization signal sent when refreshing of a specific row of the screen starts, and the second signal is a second synchronization signal sent when refreshing of the specific row of the screen is completed;
specifically, the screen may be connected to a motherboard of the VR device, and the motherboard may receive a signal sent by the screen. The signal may be a synchronization signal T1 (first signal, also the first synchronization signal) sent each time a refresh of a specific row of the screen starts, or another synchronization signal T2 (second signal, also the second synchronization signal) sent each time a refresh of a specific row of the screen completes. Since the screen refreshes only a specific row, the refresh of a specific row of the screen is started, which can be understood as the time when the screen starts to refresh. Wherein the particular row may be an odd row or an even row.
When the terminal determines that the first signal is obtained, the terminal executes step S130.
S130, stopping sending the polarized light;
specifically, in one implementation, an electrically-powered polarizer may be placed in front of the screen, and this electrically-powered polarizer may be connected to the motherboard. The polarizing plate has a function of shielding and transmitting incident light, and can transmit polarized light with the vibration direction same as the polarization direction of the polarizing plate and shield the polarized light with the vibration direction perpendicular to the polarization direction of the polarizing plate.
Based on the principle, when the terminal determines that the obtained signal is the first signal, i.e. the T1 signal, the terminal may control the electric polarizer to set the polarization direction of the electric polarizer to be perpendicular to the vibration direction of the polarized light, so as to shield the polarized light, thereby implementing: the transmission of the polarized light is stopped. At this time, the polarized light cannot be received by both eyes of the user, and the screen of the VR device cannot be seen.
Alternatively, the terminal executes step S140 when determining that the second signal is obtained.
S140, judging whether the liquid crystal in the screen is turned over; if yes, executing S150, otherwise, ending;
specifically, when the terminal determines that the obtained signal is the second signal, i.e., the T2 signal, it indicates that the refresh of a specific row of the screen is completed. The turning of the liquid crystal needs a certain time, so that the electric polaroid can be controlled to transmit the polarized light to display after the liquid crystal in a specific line of the screen is turned over, and accordingly, when the user sees the screen with both eyes, the phenomenon of smear is reduced because the liquid crystal is already turned over.
For example, assuming that the liquid crystal flipping time is T, timing may be started at the time when the motherboard receives the T2 signal, and when the timing duration reaches T, it may be determined that the liquid crystal in the screen has been flipped, and further the subsequent method steps are performed. The screen only refreshes the specific row, and whether the liquid crystal in the screen is turned over is judged, namely whether the liquid crystal in the specific row in the screen is turned over is judged. Of course, any other determination method that can achieve the completion of the liquid crystal flipping in the screen belongs to the protection scope of the embodiment of the present invention, and is not repeated herein.
S150, transmitting the polarized light.
Specifically, after it is determined that the liquid crystal in the screen has been turned over, the electric polarizer may be controlled to set the polarization direction of the electric polarizer to the same direction as the vibration direction of the polarized light, so that the polarized light passes through the electric polarizer, thereby implementing: and transmitting the polarized light. Thus, both eyes of the user can receive the polarized light, and then the screen of the VR device at the moment can be seen.
Therefore, as only the odd lines or the even lines are refreshed, the resolution of the liquid crystal screen image seen by the two eyes of the user is lost by half, but when the two eyes of the user see the image displayed on the screen, the liquid crystal in the screen is turned over, so that the smear generated by the liquid crystal screen display is reduced, and compared with the method of using the fast-response liquid crystal and the O L ED screen to replace the original display screen, the cost of the VR equipment can be saved.
As a refinement of the embodiment shown in fig. 1, in another embodiment provided by the present invention, a first polarizer is disposed on the screen of the terminal, and the first polarizer is used for converting light rays emitted from a specific line in the screen into polarized light rays.
The customized polarizer attached to the screen is the first polarizer. In practical applications, the first polarizer may be other polarizers capable of converting light rays emitted from a specific line in the screen into the above polarized light rays, and this is also possible. In addition, compared with the replacement of the screen, the cost is lower by arranging the first polaroid on the screen, and the refresh rate can be improved under the condition of not increasing the burden.
As a refinement of the above embodiment shown in fig. 1, in another embodiment provided by the present invention, as shown in fig. 2, the step S110 may specifically include the following steps:
and S111, converting the light generated by the light source into light in a preset direction through the linear polarizer by the terminal.
In an embodiment of the present invention, the screen of the terminal may include a light source, a linear polarizer, and a liquid crystal pixel array. Wherein the linear polarizer is positioned between the light source and the liquid crystal pixel array. When light generated from the light source at the end passes through the linear polarizer, the light passing through the linear polarizer has only a predetermined direction since only light in a specific direction passes through the linear polarizer. That is, the linear polarizer may convert the light generated from the light source into the light having the predetermined direction, and for example, if the linear polarizer is a horizontal polarizer, since only the light having the horizontal direction passes through the linear polarizer, the light passing through the linear polarizer is a horizontal light.
The embodiment of the invention can achieve corresponding effect by adjusting the setting position of the linear polaroid. For example, if the linear polarizer is rotated by 90 °, a horizontal polarizer can be converted to a vertical polarizer. The horizontal polarizer is equivalent to passing only the horizontal polarization direction light, and the vertical polarizer is equivalent to passing only the vertical polarization direction light.
And S112, the terminal converts the light emitted by the liquid crystal display array of the specific row in the screen into polarized light by controlling the liquid crystal display array in the screen, and stops the light emitted by the liquid crystal display arrays of the other rows except the specific row in the screen.
In the embodiment of the invention, after the light in the preset direction reaches the linear liquid crystal pixel array, the terminal can convert the light emitted by the liquid crystal display array in the specific row in the screen into the first polarized light by driving the liquid crystal pixels in the liquid crystal pixel array, and stop the light emitted by the liquid crystal display arrays in the other rows except the specific row in the screen. Wherein the specific row refers to an odd row or an even row.
The embodiment of the invention can accurately control the light rays emitted by the odd lines or the even lines in the screen by changing the structure of the terminal screen.
In another embodiment provided by the present invention, a second polarizer is further disposed on the terminal; the stopping of the transmission of the polarized light may include: the terminal controls the second polarizer, sets the polarization direction of the second polarizer to be a direction perpendicular to the vibration direction of the polarized light, and prevents the polarized light from transmitting through the second polarizer.
Specifically, the electrically-driven polarizing plate described above may be used as the second polarizing plate. In practice, the second polarizer may be another polarizer that can be controlled to prevent polarized light from passing through itself, and this is also possible.
The second polarizer may be controlled to rotate until the polarization direction of the second polarizer is perpendicular to the vibration direction of the polarized light, for example, the vibration direction of the polarized light is horizontal, and the polarization direction of the second polarizer is vertical. Based on the principle of the polarizer, the polarized light cannot pass through the second polarizer, and the user cannot see the screen of the VR device with both eyes. The control mode is simple and quick, the screen does not need to be replaced, the control mode can be realized by presetting an electric polaroid in VR equipment, and the cost is lower. Furthermore, the introduction of an electrically driven polarizer into the VR system can increase the refresh rate without increasing the system load.
As a refinement of the above embodiment shown in fig. 1, in a further embodiment provided by the present invention, a second polarizer is further disposed on the terminal. As shown in fig. 3, step S150 may specifically include the following steps:
s151, the terminal controls the second polarizer, and sets a polarization direction of the second polarizer to be the same as a vibration direction of the polarized light, so that the polarized light transmits through the second polarizer;
and S152, displaying the transmitted polarized light by the terminal.
Specifically, the second polarizing plate may be the aforementioned electric polarizing plate. The second polarizer may be controlled to rotate until the polarization direction of the second polarizer is the same as the vibration direction of the polarized light, for example, both horizontal directions or both vertical directions. Therefore, based on the principle of the polarizer, the polarized light can be transmitted through the second polarizer to display the transmitted polarized light, and the user can see the picture of the screen in the VR device with both eyes. This kind of control mode is simple swift, need not change the screen, can realize through set up an electronic polaroid in advance in VR equipment, practices thrift the cost.
It will be understood by those skilled in the art that the parity refresh mechanism and polarization technique of the existing screen are mainly used for 3D display of tv, and not for solving the smear generated by VR display. Using this mechanism and technique in VR devices, the image format of the screen display, and the control of the motorized polarizer are not the same. In practical applications, the image format may be customized, and any control method of the second polarizer belongs to the protection scope of the present invention, which is not repeated herein.
Exemplarily, fig. 4 is an application block diagram of a screen display method according to an embodiment of the present invention. As shown in fig. 4, the screen with the polarizing plate attached emits a sync signal T1 every time a refresh is started, and also emits a sync signal T2 after all the particular rows are refreshed. The screen is connected with the main board, and the main board can obtain synchronous signals T1 and T2 emitted by the screen. An electrically driven polarizer is placed in front of the screen and connected to the main board.
After the main board obtains the synchronous signal, the polarization direction of the electric polaroid is controlled according to signals T1 and T2. When the mainboard receives a T1 signal, the polarization direction of the electric polarizer is arranged in the direction vertical to the vibration direction of the polarized light, so that the polarized light cannot penetrate through the electric polarizer; when the motherboard receives the T2 signal, the polarization direction of the electrically-operated polarizer is set to the same direction as the vibration direction of the polarized light beam in the case where the liquid crystal inversion has been completed, and the polarized light beam is transmitted.
Although half of the resolution of the screen is lost, the liquid crystal is turned over when the user sees the screen, so that the smear is reduced.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a screen display device according to an embodiment of the present invention, and corresponding to the flow shown in fig. 1, the screen display device may include: a conversion module 510, an obtaining module 520, a stop sending module 530, a judgment module 540 and a sending module 550;

the second conversion unit 512 is configured to convert, by the terminal, the light emitted by the liquid crystal display array in the specific row in the screen into polarized light by controlling the liquid crystal display array in the screen, and stop the light emitted by the liquid crystal display arrays in the other rows except the specific row in the screen.
Specifically, a second polarizing film is further arranged on the terminal; the stop sending module 530 is further configured to:
the terminal controls the second polarizer, sets the polarization direction of the second polarizer to be a direction perpendicular to the vibration direction of the polarized light, and prevents the polarized light from transmitting through the second polarizer.

and a display unit 552 for displaying the transmitted polarized light by the terminal.
Therefore, as only the odd lines or the even lines are refreshed, the resolution of the liquid crystal screen image seen by the two eyes of the user is lost by half, but when the two eyes of the user see the image displayed on the screen, the liquid crystal in the screen is turned over, so that the smear generated by the liquid crystal screen display is reduced, and compared with the method of using the fast-response liquid crystal and the O L ED screen to replace the original display screen, the cost of the VR equipment can be saved.
