Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived from the embodiments in the present application by a person skilled in the art, are within the scope of protection of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.

The display module, the electronic device, and the video playing method provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

In the related art, to implement three-dimensional (3D) imaging, a device for displaying needs to output two different video contents (i.e., two video sources) corresponding to the left and right eyes of a person, respectively, and the light polarization directions of the two contents need to be perpendicular to each other, so that the two contents can be distinguished by 3D glasses and then enter corresponding eyeballs, respectively, and the three-dimensional image is seen by the person through brain synthesis processing.

However, the display module of the electronic device cannot meet the above requirements, for example, the electronic device such as a mobile phone, a tablet, a computer, a television, and Virtual Reality (VR) glasses used in daily life is usually a screen (i.e., only one video source). Secondly, because the Display principle of a Liquid Crystal Display (LCD) needs to use polarization change to control color and brightness, light emitted from the LCD screen cannot have different polarization directions with different contents, and cannot simultaneously emit contents with two polarization directions perpendicular to each other. In addition, the image is separated into two groups of pictures of vertical polarized light and horizontal polarized light, and then the two groups of pictures are watched by using 3D glasses, so that the left eye and the right eye of a person can receive the two groups of pictures, and then the three-dimensional image is synthesized by the brain. However, due to the adoption of the imaging principle of the spectroscopic method, the resolution of the picture is halved, so that the real full-high-definition 3D image is difficult to realize, and the brightness of the picture is reduced.

However, an embodiment of the present application provides a display module, an electronic device, and a video playing method, in which a liquid crystal layer is added in a structure of an Organic Light-Emitting Diode (OLED) display module to adjust a polarization direction of Light of the OLED display module, and frame synchronization signals are used as synchronization signals to perform frame interpolation sequencing on signals of two video sources and output the signals from the same display module, and the synchronization signals are used to control the display module to perform periodic polarization direction adjustment, so that Light emitted by the display module from the video sources corresponding to left and right eyes is re-adjusted to Light of different polarization directions, so that the two video sources can be displayed on the same display interface, thereby implementing a function of playing a 3D video by the electronic device, and having no influence on image resolution.

Fig. 1 shows a schematic view of a possible structure of a display module provided in an embodiment of the present application, and as shown in fig. 1, the display module includes: the display module is used for emitting target polarized light; the liquid crystal layer is arranged on the surface of the display module, which emits the target polarized light; and the driving module is electrically connected with the liquid crystal layer and used for outputting voltage to the liquid crystal layer according to the image frame corresponding to the target polarized light so as to control the liquid crystal layer to be switched between a first state and a second state.

Optionally, in this embodiment of the application, when the target video data is loaded to the display module, the display module controls a current flowing through the OLED, excites the organic light emitting layer to emit light, and emits a target polarized light corresponding to the target video data through the polarizer, where the target video data may be 3D video data.

Alternatively, in the embodiment of the present application, the liquid crystal layer may be disposed on a side of the polarizer, the side of the polarizer is far away from the organic light emitting layer, and the size of the liquid crystal layer may be adapted to the polarizer.

Optionally, in this embodiment of the application, the driving module may specifically be a display driving chip, and the display driving chip may control a voltage of the liquid crystal layer according to the frame synchronization signal, and change a rotation direction of the liquid crystal molecules, so as to control the liquid crystal layer to switch between the first state and the second state.

In the embodiment of the application, when the liquid crystal layer is in the first state, the first polarized light can penetrate through the liquid crystal layer; when the liquid crystal layer is in the second state, the second polarized light can penetrate through the liquid crystal layer; the first polarized light and the second polarized light have different polarization directions.

Note that the above "the liquid crystal layer is switched between the first state and the second state" can be understood as follows: the rotation direction of the liquid crystal molecules can be changed by changing the voltage, when the liquid crystal molecules are arranged in a first arrangement mode, the liquid crystal layer is in a first state, and in the first state, light with the polarization direction being a first polarization direction can pass through the liquid crystal layer; when the liquid crystal molecules are arranged in a second arrangement mode, the liquid crystal layer is in a second state, and light with the polarization direction being a second polarization direction can pass through the liquid crystal layer in the second state; the first direction and the second direction are perpendicular.

Under the condition that the image frame corresponding to the target polarized light emitted by the display module is the first image frame, the display module of the electronic equipment outputs voltage to the liquid crystal layer so that the liquid crystal layer is in a first state, and therefore the first polarized light corresponding to the first image frame can penetrate through the liquid crystal layer; under the condition that the image frame corresponding to the target polarized light emitted by the display module is a second image frame, the driving module outputs voltage to the liquid crystal layer to enable the liquid crystal layer to be in a second state, so that second polarized light corresponding to the second image frame can penetrate through the liquid crystal layer; and the polarization directions of the first polarized light and the second polarized light are different, so that two groups of pictures with different polarization directions respectively enter corresponding eyeballs after being distinguished by the 3D glasses and are synthesized by the brain to enable a viewer to see a stereoscopic image, the problem that the image quality of the image is reduced due to the fact that the image is separated by a pixel separation method is avoided, and the electronic equipment can display the high-definition stereoscopic image.

Fig. 3 shows a flowchart of a video playing method provided in this embodiment, which is applied to the electronic device in the foregoing embodiment. As shown in fig. 3, a video playing method provided in an embodiment of the present application may include

steps

101 and 102 described below.

Step 101, the electronic device obtains a target video.

In this embodiment of the application, the target video includes N first image frames and M second image frames, shooting angles of the first image frames and the second image frames are different, and N and M are both positive integers greater than 1.

Optionally, in this embodiment of the present application, the target video may include 3D video Data obtained after a Data Processing Unit (DPU) performs Processing according to a target Processing manner, where the 3D video Data includes left-eye video Data and right-eye video Data. The left-eye video data may be video data captured by the image capture device from a left-eye viewing angle, and the right-eye video data may be video data captured by the image capture device from a right-eye viewing angle.

Further optionally, in this embodiment of the application, the left-eye video data may be data corresponding to a video formed by arranging N first image frames according to a first time sequence; the right-eye video data may be data corresponding to a video formed by arranging M second image frames in a second time sequence. Wherein the first time sequence is the time sequence when the camera device shoots the video from the left eye visual angle; the second time sequence is a time sequence when the image pickup apparatus photographs a video from the right-eye viewpoint.

Optionally, in this embodiment of the present application, after the left-eye video data and the right-eye video data stored in the memory of the electronic device are loaded into the DPU of the electronic device, the image frame sequence is alternately sequenced on the N first image frames and the M second image frames according to a target processing mode, so as to obtain a target video stream.

In an example, the target processing manner may be: a second image frame is inserted after each first image frame.

In another example, the target processing manner may be: one second image frame is inserted after every two first image frames. Step 102, the electronic device controls a liquid crystal layer of the electronic device to switch between a first state and a second state according to an image frame currently played by the electronic device in the process of playing the target video.

In the embodiment of the application, when the electronic device plays a first image frame currently, the liquid crystal layer is controlled to be in a first state, so that a first polarized light can penetrate through the liquid crystal layer; when the electronic equipment plays the second image frame currently, the liquid crystal layer is controlled to be in a second state, so that the second polarized light can penetrate through the liquid crystal layer; the first polarized light and the second polarized light have different polarization directions.

Optionally, in this embodiment, while sending the frame synchronization signal for controlling the target video output to the display module, the integrated processor (System On a Chip, SOC) of the electronic device also sends a synchronization signal with a timing consistent with that of the frame synchronization signal to the driving module, so as to control the liquid crystal layer of the electronic device to switch between the first state and the second state.

Optionally, in this embodiment of the application, the first polarized light may be light emitted by a display module of the electronic device for displaying a first image frame in the left-eye video, where a polarization direction of the first polarized light is a first polarization direction, and the first polarization direction may be any one of the following directions: horizontal and vertical.

Optionally, in this embodiment of the application, the second polarized light is light emitted by a display module of the electronic device for displaying a second image frame in the right-eye video, and a polarization direction of the second polarized light is a second polarization direction, where the second polarization direction may be any one of the following: horizontal and vertical.

Wherein the first polarization direction and the second polarization direction are different.

Optionally, in this embodiment of the application, when the liquid crystal layer is in the first state, the light with the polarization direction being the first polarization direction may pass through the liquid crystal layer; when the liquid crystal layer is in the second state, light with the second polarization direction can pass through the liquid crystal layer.

It can be understood that, when the electronic device plays the first image frame, the display module emits the first polarized light with the first polarization direction, and the electronic device controls the driving module to adjust the liquid crystal layer to be in the first state, so that the first polarized light can penetrate through the liquid crystal layer; when the electronic device plays the second image frame, the display module emits a second polarized light with the polarization direction being the second polarization direction, and the electronic device controls the driving module to adjust the liquid crystal layer to be in the second state, so that the second polarized light can penetrate through the liquid crystal layer.

The following describes how the electronic device controls the liquid crystal layer of the electronic device to switch between the first state and the second state according to the currently played image frame.

Optionally, in this embodiment of the application, as shown in fig. 4 in combination with fig. 1, the step 102 may be specifically implemented by a step 102a described below.

Step 102a, under the condition that the electronic device displays the jth first image frame, if the display module of the electronic device receives a frame synchronization signal, updating the jth first image frame to a kth second image frame, and controlling the liquid crystal layer to be in the second state through the driving module of the electronic device.

In this embodiment of the application, the frame synchronization signal may control a first image frame in the left-eye video and a second image frame in the right-eye video stream to be alternately output to a display module of the electronic device according to a target sequence, where the target sequence is an arrangement sequence of the first image frame and the second image frame in the target video stream.

It can be understood that, after the first image frame in the left-eye video and the second image frame in the right-eye video are processed by the DPU, the timestamp output to the display module of the electronic device is obtained, and the timestamp indicates the time point, the duration and the sequence of the output of the first image frame and the second image frame.

Optionally, in this embodiment of the application, while the display module of the electronic device receives the frame synchronization signal, the driving module receives a synchronization signal whose timing is consistent with that of the frame synchronization signal, so as to control the liquid crystal layer of the electronic device to switch between the first state and the second state.

For example, as shown in fig. 5, when the display module of the electronic device is displaying the 1 st first image frame in the target video, the driving module controls the liquid crystal layer to be in the first state at this time, so that the first polarized light emitted by the first image frame through the display module can penetrate through the liquid crystal layer, if the display module of the electronic device receives the frame synchronization signal and indicates to display the 1 st second image frame in the target video, the 1 st first image frame is updated to the 1 st second image frame, because the synchronization signal received by the driving module is consistent with the frame synchronization signal in time sequence, at this time, the synchronization signal simultaneously indicates the driving module to control the liquid crystal layer of the electronic device to be updated from the first state to the second state, so that the second polarized light emitted by the second image frame through the display module can penetrate through the liquid crystal layer.

Optionally, in this embodiment of the application, when the electronic device displays a kth second image frame, if the display module receives a frame synchronization signal, the kth second image frame is updated to a j +1 th first image frame, and the liquid crystal layer is controlled to be in the first state by the driving module.

For example, as shown in fig. 5, when the display module of the electronic device is displaying the 1 st second image frame in the target video, the driving module controls the liquid crystal layer to be in the second state at this time, so that the second polarized light emitted by the second image frame through the display module can penetrate through the liquid crystal layer, if the display module of the electronic device receives the frame synchronization signal and indicates to display the 2 nd first image frame in the target video, the 1 st second image frame is updated to the 2 nd first image frame, because the synchronization signal received by the driving module is consistent with the frame synchronization signal in time sequence, at this time, the synchronization signal simultaneously indicates the driving module to control the liquid crystal layer of the electronic device to be updated from the second state to the first state, so that the first polarized light emitted by the first image frame through the display module can penetrate through the liquid crystal layer.

In the embodiment of the application, j and k are positive integers.

Optionally, in the embodiment of the present application, the positive integers j and k may be the same or different.

Therefore, under the condition that the electronic equipment displays the jth first image frame, if a display module of the electronic equipment receives a frame synchronization signal, the jth first image frame is updated to the kth second image frame, the liquid crystal layer is controlled to be in the second state through a driving module of the electronic equipment, and under the condition that the electronic equipment displays the kth second image frame, if the display module receives the frame synchronization signal, the kth second image frame is updated to be the (j + 1) th first image frame, the liquid crystal layer is controlled to be in the first state through the driving module, and so on, so that two light rays with different polarization directions can be emitted from the display module without mutual interference, and the light rays are distinguished by the 3D glasses and then respectively enter corresponding eyeballs, and a viewer sees a high-definition stereo image through brain synthesis.

According to the video playing method provided by the embodiment of the application, the electronic device can acquire the target video comprising the N first image frames and the M second image frames, and in the process of playing the target video, if the first image frame is played currently, the liquid crystal layer is controlled to be in the first state, so that the first polarized light can penetrate through the liquid crystal layer; when the electronic equipment plays the second image frame currently, the liquid crystal layer is controlled to be in the second state, so that the second polarized light can penetrate through the liquid crystal layer, the shooting angles of the first image frame and the second image frame are different, and the polarization directions of the first polarized light and the second polarized light are different, therefore, two groups of pictures with different polarization directions are distinguished by the 3D glasses and respectively enter the corresponding eyeballs and are synthesized by the brain to enable a viewer to see a stereoscopic image, the problem that the image quality is reduced due to the fact that the image is separated through a pixel separation method is avoided, and therefore the electronic equipment can display the high-definition stereoscopic image.

How the electronic device acquires the target video is explained in detail below.

Optionally, in this embodiment of the application, with reference to fig. 1, as shown in fig. 6, the step 101 may be specifically implemented by a step 101a described below.

Step 101a, the electronic device inserts the M second image frames into the N first image frames to obtain the target video.

Optionally, in this embodiment of the application, the electronic device loads unprocessed video source data in the memory into the DPU, and the DPU processes the left-eye video and the right-eye video in the video source data separately according to the target processing method to obtain the target video.

Further alternatively, in this embodiment of the application, the target processing manner may be that Y second image frames are inserted after every X first image frames, a display order of the X first image frames is consecutive, and a display order of the Y second image frames is consecutive. Wherein X and Y are both positive integers.

In one example, the electronic device inserts 1 second image frame after every 2 first image frames, the display order of the 2 first image frames being consecutive. For example, the image frame display sequence of the target video is: the 1 st frame is the 1 st frame of the first image frame, the 2 nd frame is the 2 nd frame of the first image frame, the 3 rd frame is the 1 st frame of the second image frame, the 4 th frame is the 3 rd frame of the first image frame, the 5 th frame is the 4 th frame of the first image frame, the 6 th frame is the 2 nd frame of the second image frame \8230, 8230and so on.

In another example, the electronic device inserts 2 second image frames after every 3 first image frames, the display order of the 3 first image frames being consecutive and the display order of the 2 second image frames being consecutive. For example, the image frame display order of the target video stream is: the 1 st frame is the 1 st frame of the first image frame, the 2 nd frame is the 2 nd frame of the first image frame, the 3 rd frame is the 3 rd frame of the first image frame, the 4 th frame is the 1 st frame of the second image frame, the 5 th frame is the 2 nd frame of the second image frame, the 6 th frame is the 4 th frame of the first image frame, the 7 th frame is the 5 th frame of the first image frame, the 8 th frame is the 6 th frame of the first image frame, the 9 th frame is the 3 rd frame of the second image frame, the 10 th frame is the 4 th frame of the second image frame \ 8230, and so on.

Therefore, the electronic device can insert the M second image frames into the N first image frames to obtain the target video, so that the electronic device can alternately display two images

And images corresponding to different video sources are classified.

The following description will specifically describe how the electronic device acquires the target video by taking an example of inserting a second image frame after each first image frame.

Optionally, in this embodiment of the application, with reference to fig. 6 and as shown in fig. 7, the step 101a may be specifically implemented by the following step 101a 1.

Step 101a1, the electronic device inserts the ith second image frame of the M second image frames into the ith first image frame of the N first image frames.

In the embodiment of the application, i is a positive integer.

Optionally, in this embodiment of the application, the N first image frames may be a group of sequential image frames formed after the left-eye video is arranged according to the shooting order; the M second image frames may be an ordered group of image frames formed after the right-eye video is arranged according to the shooting order.

Optionally, in this embodiment of the application, the electronic device may merge an ith second image frame of the M second image frames into an ordered group of image frames, that is, the target video, after inserting the ith second image frame of the N first image frames.

Further optionally, in this embodiment of the application, the target video may be a group of image frames in which a single first image frame and a single second image frame are alternately arranged.
