first embodiment

Referring to FIG. 1, there is shown a flowchart of a content display method according to an embodiment of the present invention, which is applied to a mobile terminal with a flexible screen. The method may specifically include the following steps:

Step 101, detecting the bending information of the flexible screen in real time;

Among them, for a mobile terminal with a flexible screen (such as a mobile phone), in order to prevent the user from deforming the screen when using the mobile phone, causing the user to browse inconveniently, the method of the embodiment of the present invention can set a sensing device on the surface of the flexible screen, so that real-time Detect the bending information of the flexible screen.

Among them, as for the type of the sensing device, with the development of scientific and technological materials such as graphene, there are many types of the sensing device, and the present invention does not specifically limit the type of the sensing device. For example, an inductive device including a capacitive device can be used for detection. The specific principle is to detect the bending of the flexible screen through the capacitance change detected by the inductive device, so as to obtain the bending information.

Step 102, establishing a two-dimensional bending table according to the bending information;

Wherein, after the bending information is detected by the sensing device, the bending information can be acquired, and a two-dimensional bending table can be established according to the bending information. Among them, for the bending two-dimensional table, that is, a two-dimensional table composed of bending information, each information in the two-dimensional table records the bending information representing each pixel on the flexible screen, so that each pixel on the flexible screen can be determined. The degree of curvature of a pixel.

Step 103, based on the curved two-dimensional table and the hardware parameter information of the flexible screen, perform spatial projection transformation processing on the flexible screen to obtain a corrected two-dimensional table;

Wherein, according to the established curved two-dimensional table and the hardware parameter information of the flexible screen, the flexible screen can be subjected to spatial projection transformation processing to obtain the corrected two-dimensional table, and each information record in the corrected two-dimensional table represents each The curvature correction information of each pixel point.

Step 104, correcting the content displayed on the flexible screen according to the two-dimensional correction table.

Wherein, the content displayed on the flexible screen can be corrected by the scaling degree according to the two-dimensional correction table, so as to obtain the displayed content that looks stable.

In this way, in the embodiment of the present invention, the bending degree of the flexible screen is determined by detecting the bending information of the flexible screen and establishing a two-dimensional bending table; and the spatial projection transformation of the flexible screen is performed by using the two-dimensional bending table and the hardware parameter information of the flexible screen. processing to obtain a correction two-dimensional table, so that the degree of correction of the content displayed on the screen can be determined; through the correction two-dimensional table, the content displayed on the flexible screen can be corrected, so that the distortion caused by the flexible screen can be corrected. The displayed content becomes smooth, and even if the flexible screen is curved, the content displayed on it still appears to be displayed normally rather than deformed, thereby improving user experience.

Second Embodiment

Referring to FIG. 2 , a flowchart of a content display method according to another embodiment of the present invention is shown, which is applied to a mobile terminal with a flexible screen. The method may specifically include the following steps:

Step 201, detecting the bending information of the flexible screen in real time;

The bending information may include an absolute bending angle and a relative bending angle.

The absolute bending angle is the absolute bending angle information of the pixel (for example, the pixel is bent by 4 degrees); and the relative bending angle of the pixel is the bending angle information of the pixel relative to the surrounding pixels. Specifically, multiple (here, two) adjacent pixels around the pixel are bent by 2 degrees and 3 degrees respectively, and the absolute bending angle of the pixel is 4 degrees, then here, the relative The bending angle information is 1 degree).

Among them, when the sensing device detects the bending angle of each pixel on the flexible screen, some pixels detect the absolute bending angle, some pixels detect the relative bending angle, and some pixels detect both the absolute bending angle and Relative bend angle detected. Therefore, the bending information here includes both the absolute bending angle and the relative bending angle.

In addition, when detecting the bending information, the embodiment of the present invention can not only use the sensing device in the embodiment shown in FIG. 1, but also use auxiliary detection devices such as a gyroscope and/or a camera to detect the bending information. Taking the gyroscope as an example, the gyroscope can be installed on the side of the flexible screen of the mobile terminal, then when the gyroscope on the side detects the tilt information of the flexible screen, the tilt information can be sent to the sensing device to detect the The bending information detected by the sensing device alone is corrected for accuracy; for the camera, its principle is to detect the bending information of the flexible screen through the plane change of the captured picture, and send this bending information to the sensing device to sense the The bending information detected by the device is corrected for precision. Thereby, the accuracy and precision of the bending information detected by the embodiments of the present invention can be increased.

Optionally, before step 201 is performed, the method in this embodiment of the present invention may further include: receiving a preset operation of the mobile terminal by the user of the mobile terminal (for example, the mobile terminal is provided with a button for whether to enter the curved surface stable display mode, which can be clicked on). button to enter this mode), and then put the mobile terminal in the curved stable display mode.

In this way, the user can be provided with an opportunity to choose whether to correct the displayed content on the flexible screen, instead of directly placing the mobile terminal in this correction mode, so that the content display mode has more flexibility in choice.

Step 202 , according to the bending information, determine the bending angle of each pixel on the flexible screen relative to surrounding pixels.

Among them, for the bending information of each pixel point on the flexible screen, the pixel point A may only detect the absolute bending angle information, and the pixel point B may detect the relative bending angle information.

Therefore, if the bending information of the pixel points is relative bending angle information, it can be obtained directly, while for some pixel points whose bending information is absolute bending angle information, conversion processing is required, that is, for this part of the pixels, it is necessary to The absolute bending angle of the surrounding pixels is used to determine the relative bending angle information of the pixel relative to the surrounding pixels, so as to obtain the bending angle (ie, the relative bending angle) of each pixel relative to the surrounding pixels.

Since the pixels laid out on the flexible screen have a three-dimensional structure, the layout of the surrounding pixels of each pixel can be divided into the surrounding pixels of the X-Y plane, and the surrounding pixels of the X-Z and Y-Z planes. Therefore, when determining the bending angle of each pixel point relative to the surrounding pixel points, that is, the specificity of the step 202 may be implemented in the following manner: each pixel on the flexible screen may be determined according to the bending information The first bending angle of the point relative to the surrounding pixels in the horizontal direction (that is, the surrounding pixels of the X-Y plane), and the second bending angle relative to the surrounding pixels in the vertical direction (that is, the surrounding pixels of the X-Z and Y-Z planes) Bend angle. That is, the relative bending angle includes the relative bending angle on the horizontal plane and the relative bending angle on the vertical plane.

Step 203 , establishing the two-dimensional bending table according to the bending angle.

Among them, when the two-dimensional bending table is established according to the bending angle, the bending angle of each pixel point relative to the surrounding pixel points is divided into two categories. Then, in order to make the curved two-dimensional table simpler and faster to build, therefore, a first curved two-dimensional table can be built according to the first curved angle; and a second curved two-dimensional table can be built according to the second curved angle. Among them, by establishing two types of curved two-dimensional tables, the number of the two-dimensional tables can be reduced, the error rate can be reduced, and the building speed of the two-dimensional tables can be provided (which can be built in parallel).

That is to say, two types of curved two-dimensional tables can be established for each pixel point on the flexible screen, one is a horizontal curved two-dimensional table, and the other is a vertical curved two-dimensional table. Among them, no matter which two-dimensional table is, the row represents the record, and the column represents the attribute. For the horizontally curved two-dimensional table, each record represents the bending angle value of each pixel relative to the surrounding pixels in the horizontal direction, and each column represents the attributes of the two-dimensional table, including the pixel ID, The bending angle between this pixel and surrounding pixels in each horizontal direction. The vertically curved two-dimensional table is similar to the horizontally curved two-dimensional table, and details are not described here.

Step 204, based on the curved two-dimensional table and the resolution parameters of the flexible screen, perform spatial projection transformation processing on each pixel on the flexible screen to obtain the correction parameters of each pixel relative to surrounding pixels. ;

Wherein, according to the respective record information in the first curved two-dimensional table and the second curved two-dimensional table and the screen resolution of the flexible screen, spatial projection transformation processing can be performed on each pixel on the flexible screen, so as to obtain each pixel point of the flexible screen. Correction parameter between pixels relative to surrounding pixels.

Specifically, for example, a part of the flexible screen becomes a waveform, then take the peak part as an example, if the method of the embodiment of the present invention is not used, the text displayed on the peak part will look smaller, and only a part of the text can be seen , other parts are invisible. Then, the pixels on the flexible screen can be spatially projected according to the relative bending angle between each pixel and the surrounding pixels in the two curved two-dimensional tables, as well as the actual physical distance between each pixel on the flexible screen. Transformation processing, so that the degree of scaling (here, zooming) of the pixels of the text in the peak part relative to the surrounding pixels can be determined.

Optionally, before step 204, the method according to the embodiment of the present invention further includes: comparing the size of the flexible screen with a preset size threshold; when the size of the flexible screen is smaller than the preset size threshold, Based on the curved two-dimensional table and the hardware parameter information of the flexible screen, a horizontal projection transformation process is performed on the flexible screen to obtain the corrected two-dimensional table; that is, when facing a flexible screen with a smaller size , the embodiment of the present invention can perform horizontal projection to obtain a corrected two-dimensional table. And when the size of the flexible screen is greater than the preset size threshold, based on the curved two-dimensional table and the hardware parameter information of the flexible screen, the flexible screen is subjected to arc-shaped projection transformation processing to obtain the Describe the correction two-dimensional table. That is to say, when the size of the flexible screen is large, due to the visual angle of the human eye, each pixel on the flexible screen can be subjected to arcuate projection transformation processing to obtain a corrected two-dimensional table.

Step 205: Generate a two-dimensional correction table according to the correction parameters.

Among them, since each pixel on the flexible screen corresponds to a correction parameter (for example, the scaling degree of each pixel relative to the surrounding pixels), a correction two-dimensional table can be generated.

Step 206, correcting the content displayed on the flexible screen according to the two-dimensional correction table.

Among them, the content displayed on the flexible screen can be corrected according to the zoom degree information of each pixel point in the correction two-dimensional table, so that the deformed text is displayed on a plane after correction, reducing the It solves the problem of unstable content display caused by the curved appearance of the flexible screen.

With the above technical solutions of the embodiments of the present invention, the embodiments of the present invention can correct the content displayed on the flexible screen by means of the detected bending information of each pixel on the flexible screen, so that the content displayed on the flexible screen does not change. Due to the bending of the flexible screen, the content display will be deformed, which will affect the user's browsing experience of the content; in addition, when correcting the pixels on the flexible screen, not only the relative bending angle of the pixels on the flexible screen is used, but also the flexible screen. Resolution parameter, the software information and hardware information are combined to determine the correction parameter of the pixel point, so that the determination of the correction parameter is more accurate, and the correction accuracy of the display content is improved.
