The terminal can be a mobile phone, a tablet computer, a personal digital assistant or a wearable device.

Those skilled in the art will appreciate that the configuration shown in fig. 1 is a block diagram of only a portion of the configuration relevant to the present application, and does not constitute a limitation on the terminal to which the present application is applied, and that a particular terminal may include more or less components than those shown in the drawings, or may combine certain components, or have a different arrangement of components. If the terminal further comprises a sensor connected through a system bus, the sensor may be one or more of an acceleration sensor, a gyroscope, an infrared sensor, and a bending detection sensor, and is used for detecting state information of the terminal, such as a folding area, a folding direction, and a folding amount of a display screen of the terminal.

In one embodiment, as shown in fig. 3 and 4, fig. 3 provides a schematic view of a flexible display of a terminal, and fig. 4 provides a schematic view of a side view of the flexible display of the terminal when it is folded. The flexible display screen is made of soft materials, and can be deformed and bent. Each small square in the figure represents a pixel, and each pixel has the same structure size and the same imaging effect. When the flexible display screen is folded, the pixels on the display screen are divided into pixels of the folding area 10 and pixels of the non-folding area 20. As shown in fig. 4, the pixels of the folding area 10 are deformed by compression, resulting in an increase in the pixel density of the folding area 10, so that the image displayed by the pixels of the folding area 10 is compressed. Therefore, the image of the non-folding area 20 of the flexible display screen is normally displayed, and the image of the folding area 10 is compressed, so that the local image display of the flexible display screen is abnormal, and the visual experience of the user is reduced.

FIG. 5 is a flow diagram of a display screen control method in one embodiment. The embodiment is described by taking the method applied to the terminal shown in fig. 2 as an example. The display screen control method in this embodiment is described by taking the operation on a terminal as an example. As shown in fig. 5, the display screen control method includes steps 502 to 506.

Step 502: and when the display screen is folded, acquiring the folding information of the display screen. Wherein the folding information includes a folding area and a folding amount.

When the display screen is folded, referring to fig. 4, the position of the folding area 10 of the display screen and the amount of folding of the folding area 10 may be detected based on a bending sensor (not shown in fig. 4) built in the terminal, thereby confirming the folding information of the display screen. Of course, the folding information of the display screen may also be detected based on other sensors built in the terminal, for example, a position sensor, a pressure sensor, and the like, which can detect the folding information of the display screen.

It should be understood that the amount of folding is used to characterize the degree of bending of the display screen when it is folded. For example, the folding amount may be a bending angle at the time of folding or a deformation amount of the display screen at the time of folding.

It should be noted that the above list is an example and not a limitation for determining the folding information of the display screen, and the folding information of the display screen may also be detected in other manners.

Step 504: and judging whether the folding amount is larger than a preset threshold value or not.

A preset threshold value is pre-stored in the terminal, and the preset threshold value can be set according to the visual difference of the image display of the folding area 10 and the non-folding area 20. For example, the amount of folding when there is a significant visual difference in the image display of the folded area 10 and the unfolded area 20 may be set as a preset threshold value.

Step 506: and if the folding amount is larger than the preset threshold value, controlling the pixel display of the display screen according to the folding amount.

When the display screen is folded, referring to fig. 4, the pixels in the folding area 10 are compressed or stretched (fig. 4 shows that the pixels are compressed), so that the pixels in the folding area 10 and the pixels in the non-folding area 20 have different structures, thereby causing the imaging difference between the folding area 10 and the non-folding area 20. It is understood that as the folding amount increases, the imaging difference is larger and larger, and when the folding amount is larger than the preset threshold, the picture display of the folding area 10 and the non-folding area 20 is obviously deformed.

It should be understood that when the folding amount is greater than the preset threshold, the terminal determines the position of the folding area 10 of the display screen, and the folding direction and the folding amount of the folding area 10 according to the folding information, and controls the pixel display of the folding area 10 and the non-folding area 20 of the display screen accordingly. For example, whether the image display of the folding area 10 is compressed can be determined by the folding direction, when the folding direction is inward folding, that is, folding toward the light-transmitting side of the display screen (see fig. 4, fig. 4 shows the case of inward folding of the display screen), the pixels of the folding area 10 are expressed as being squeezed, and the image display is expressed as being in a compressed state, at this time, the terminal controls the pixel driving mode of the folding area 10 to merge two rows of pixels of the folding area 10 into one row for image display, so that the compressed state of the image display of the folding area 10 is released, and the image display matching of the folding area 10 and the non-folding area 20 is realized.

The above description is given as an example of controlling the pixel display of the display panel, and is not limited thereto, and the pixel display of the display panel may be controlled by another method.

According to the display screen control method, the folding information of the display screen is obtained, when the folding amount in the folding information is larger than the preset threshold value, the pixel display of the display screen is controlled according to the folding amount, the pixel display matching of the folding area 10 and the non-folding area 20 of the display screen is realized, and the visual experience of a user is improved.

Fig. 6 is a flowchart of a method for detecting folding information in an embodiment, as shown in fig. 6, the method for detecting folding information of a display screen includes steps S602 to S608.

Step S602: a fold region of the display screen is detected.

Step S604: a fold axis for the fold region is determined.

Step S606: and judging the folding direction of the folding area along the folding axis.

Step S608: the folding amount of the folding area in the folding direction is acquired.

In this embodiment, a bending sensor is built in the terminal, and the bending sensor is a sensor for detecting folding information of the display screen. Referring to fig. 7, fig. 7 is display folding information according to an embodiment, when the display is folded, a bending sensor disposed in the terminal may detect that the folding area 10 of the display is located at a specific position of the display, a folding axis of the folding area 10, a folding direction of the folding area 10, and a folding amount R of the folding area 10. It should be noted that the display screen of the present embodiment is provided with an a surface and a B surface, where the a surface is a light-transmitting surface and is used for image display; the surface B is a display screen rear shell and plays a role in supporting and protecting. The folding direction may be defined as a first folding direction folded toward the a-side, i.e., an inner folding direction, according to the A, B sides of the display screen; and a second folding direction, i.e., an outer folding direction, folded toward the B-side. It should be understood that the folding amount R is represented by an included angle between the surfaces of the two non-folding regions 20 in the present embodiment, but other measurable amounts can be used to represent the folding amount R. For example, the surface tension of the a-side at the folding region 10, the surface tension of the B-side at the folding region 10, or the like is used, and is not particularly limited herein.

In one embodiment, the bending sensor may detect surface tension changes of the a-side and the B-side of the display screen to identify the folding area 10, and determine the surface deformation sizes of the a-side and the B-side at the folding area 10 according to the surface tension changes of the a-side and the B-side to determine the folding direction. For example, if the amount of surface deformation of the a-plane is detected to be smaller than that of the B-plane, it is determined that the folding region 10 is folded in the first folding direction (fold-in folding direction). In addition, the value of the folding amount R can be calculated according to the difference between the surface deformation of the a surface and the surface deformation of the B surface in the folding region 10, and whether the pixel display of the folding region 10 and the pixel display of the non-folding region 20 are processed differently can be determined by comparing the value of the folding amount R with a preset threshold stored in the terminal. For example, by combining two rows of pixels of the folding region 10 into one row and displaying an image, the compressed state of the image display of the folding region 10 is released, and the image display matching between the folding region 10 and the non-folding region 20 is realized.

In one embodiment, the bending sensor is formed of two conductive films in which transparent electrodes such as ITO (indium tin oxide) are arranged in a matrix. The two conductive films are disposed to face each other, and a predetermined voltage is applied to the electrode of one of the conductive films. When the display panel is folded, the resistance value between the electrodes arranged at the folding area 10 changes and a voltage corresponding to the amount of folding is generated in the electrode of the other conductive film. Therefore, the position of the folding region 10 and the folding amount R can be detected by detecting the position of the electrode in which the resistance value changes and the amount of change in voltage.

It should be noted that, in practical applications, the display screen may be slightly folded due to some error factors, and the folding amount R caused by the error factors is usually small. For example, the microfolding may be caused by material or by a slight impact. Therefore, to improve accuracy, the slight folding caused by the error factor can be ignored. Namely, when the folding quantity R of the display screen is larger than or equal to a preset threshold value stored in the terminal, the display screen is determined to be in the folding information, and at the moment, other sensors in the terminal can be started to detect the folding information of the display screen. For example, the open position sensor detects a specific position of the folding area 10, and the angle sensor detects a folding angle of the folding area 10. When the folding quantity R of the display screen is smaller than a preset threshold value stored in the terminal, the display screen is determined to be in non-folding information, and at the moment, sensors such as a position sensor and an angle sensor for detecting the folding information of the display screen are in a dormant state, so that power consumption is saved, and the endurance time is prolonged.

In one embodiment, a method of controlling display of pixels of a display screen according to an amount of folding includes: and if the folding direction is along the first folding direction, controlling pixels of at least two adjacent rows in the folding area, which are in the same direction as the folding axis, to be combined into a row of pixels for image display.

In this embodiment, as shown in fig. 8a, fig. 8a is a schematic diagram of display screen folding information in an embodiment. When the display screen is folded in a first direction, i.e. towards the a-side. At this time, the surface on the a-plane side of the pixel at the folding region 10 is pressed to be deformed so that the light transmission area of the single pixel at the region is smaller than the light transmission area of the single pixel at the non-folding region 20, thereby causing a difference in screen display between the folding region 10 and the non-folding region 20. As the folding amount R gradually increases, the picture display difference becomes larger, and when the folding amount R is larger than the preset threshold, the picture of the folding area 10 is significantly compressed (i.e., the picture size displayed by a single pixel in the non-folding area 20 is at least twice as large as that in the folding area 10). At this time, the terminal performs differential adjustment on the pixel display of the folding region 10 and the non-folding region 20, that is, controls the pixels in the folding region, which are at least two adjacent rows in the same direction as the folding axis, to be merged into one row, and performs image display.

It should be understood that the folding axis represents the intersection of the planes of the two non-folding regions 20, i.e. the display screen is folded along the folding axis, and therefore the position and direction of the folding axis determine the position of the folding region 10 and the distribution of the pixels in the folding region 10. It should be noted that the folding axis may be any straight line on the surface of the display screen. For example, when the display screen is a rectangular display screen, the folding axis may be parallel to the short side of the display screen, or may be parallel to the long side of the display screen.

It can be understood that the folding axis is located in the folding area 10, the deformation of a row of pixels along the folding axis is the same, and when the folding amount R is greater than the preset threshold, the frame of the folding area 10 is significantly compressed. For convenience of description, a picture display ratio P of the non-folding region 20 to a single pixel in the folding region 10 is defined as P, and the picture display ratio P corresponds to the folding amount R one to one. Their relationship can be expressed as: the larger the folding amount R, the larger the picture display ratio P, and the more heavily the picture at the folding area 10 is compressed.

As shown in fig. 8b, fig. 8b provides a schematic diagram of a display structure of a display panel pixel. When the screen display ratio P is 2, that is, the display screen size of a single pixel in the non-folding region 20 is 2 times the display screen size of a single pixel in the folding region 10. At this time, the terminal controls the pixels of two adjacent rows in the folding area 10, which are in the same direction as the folding axis, to be merged into one row for image display. The pixel driving mode can simultaneously light up the pixels of two adjacent rows in the folding area 10, which are in the same direction as the folding axis, and is equivalent to that the pixels of the two rows are combined into one row for image display, thereby overcoming the defect that the image display picture is compressed due to the extrusion of a single pixel, and realizing the picture display matching of the folding area 10 and the non-folding area 20. The screen display ratio P may be 3, 4 or other multiples, and the size thereof is determined according to the size of the folding amount R, and is not particularly limited herein. It should be noted that when P is 3, the display screen size of a single pixel in the non-folding region 20 is 3 times the display screen size of a single pixel in the folding region 10, and the terminal controls the pixels in three adjacent rows in the same direction as the folding axis in the folding region 10 to merge into a row of pixels for image display. By analogy, the terminal performs corresponding driving control on the pixels in the folding region 10 according to the P value (i.e. according to the folding amount R), and the control manner is similar to that when P is 2 or 3, which is not described herein again.

Fig. 9 is a flowchart of a pixel display control method of a display panel according to an embodiment, and as shown in fig. 9, the method includes controlling pixels in at least two adjacent rows in the folding area, which are in the same direction as the folding axis, to merge into a row of pixels for image display, including step S902 and step S904.

Step S902: if the pixels along the direction of the folding axis share the same scanning electrode, the scanning electrodes of at least two adjacent rows in the folding area, which are in the same direction as the folding axis, are controlled to simultaneously output scanning signals.

Step S904: and controlling the data signals output by the data electrodes in the folding area to enable the display contents of the pixels in at least two adjacent rows to be combined into pixels in one row for display.

In this embodiment, referring to fig. 10, fig. 10 provides a schematic diagram of a pixel display structure of a display screen. The display screen is distributed with pixels for image display, each pixel is distributed in a display area of the display screen in a rectangular array, and the pixels are made of organic light-emitting materials. It will be appreciated that two electrodes, respectively a scan electrode G1, G2 … … Gn and a data electrode (not shown in fig. 10), are connected to each pixel. When the scanning electrode and the data electrode are conducted, an electric field is formed, the organic light-emitting material is driven by the electric field, through carrier injection and transmission, electrons and holes are combined to form excitons, and further radiation recombination causes a light-emitting phenomenon. When the display panel is folded, the pixels in the display panel are divided into a display area including the folding area 10 and the non-folding area 20, and if the pixels along the direction of the folding axis share the same scanning electrode, that is, the scanning electrodes of a row of pixels on the folding axis are led out together (as shown in fig. 10, the same scanning electrode is led out from each row of pixels), that is, the pixels of the row are driven by the same scanning electrode. The data electrodes for the pixels in each column may be connected together or may be separately led (i.e., each pixel in each column has its own data electrode).

It should be understood that the folding axis direction in this embodiment is the direction of the row where a certain scan electrode connects each pixel. When the scan electrode is conducted with the data electrode, the pixels of the row are lighted. Therefore, on the one hand, the scan electrodes of at least two adjacent rows in the folding area, which are in the same direction as the folding axis, are controlled to simultaneously output scan signals, that is, at least two rows of pixels of the folding area 10 are simultaneously lighted when displaying, which is equivalent to that a single pixel area for image display is increased, thereby compensating the part of the pixel area of pixel compression caused by folding, and further avoiding the image of the folding area 10 from being compressed. On the other hand, the data signals output by the data electrodes in the folding area are controlled, so that the display contents of the pixels in at least two adjacent rows are combined into one row of pixels for displaying. That is, the data signals output by the data electrodes are controlled to ensure that the display content of the pixels in the folding area 10 is not changed, and only the original display content of the pixels in two or more adjacent rows is combined into one row of pixels for display, which is equivalent to stretching the originally displayed image without changing the display content.

Fig. 11 is a flowchart of a pixel display control method of a display panel in another embodiment, and as shown in fig. 11, the method includes controlling pixels in at least two adjacent rows in the folding area, which are in the same direction as the folding axis, to merge into a row of pixels for image display, including step S1102 and step S1104.

Step S1102: if the pixels along the folding axis use a scanning electrode respectively, the data signals output by the data electrodes in the folding area are controlled, and the display contents of the pixels in at least two adjacent columns are combined into one column of pixels for display.

Step S1104: the scanning mode of the scanning electrode for controlling the folding area and the non-folding area is the same.

In this embodiment, referring to fig. 12, fig. 12 provides a schematic diagram of a pixel display structure of another display panel. In the display panel, a scan electrode is used for each pixel along the direction of the folding axis, i.e. the scan electrodes of a column of pixels on the folding axis are separately led out (as shown in fig. 12, each pixel of each column corresponds to a different scan electrode), i.e. the direction of the folding axis is perpendicular to the direction of connecting the scan electrodes with the pixels. The data electrodes of the pixels in each column may be led out together or separately, and are not limited in particular. Therefore, on one hand, the data signals output by the data electrodes in the folding area are controlled, so that the display contents of the pixels in at least two adjacent columns are combined into the pixels in one column for displaying. That is, when the pixels of the display screen are lit, two or more adjacent columns of pixels in the folding area 10 are compressed, so that the pixels in the folding area 10 need to be controlled to display at least two adjacent columns of pixel display contents merged into one column of pixels, which is equivalent to that in the same row, two or more adjacent pixels in the folding area 10 share the same data electrode, so that the image contents displayed by two or more adjacent pixels are merged into one pixel for display. On the other hand, the scanning mode of the scanning electrodes for controlling the folding area and the non-folding area is the same. That is, the pixel scanning manner of the folding region 10 and the non-folding region 20 is maintained to be the same, and in an embodiment, the scanning manner may be progressive scanning, or may be simultaneous scanning of multiple rows, which is not limited herein.

In one embodiment, a method of controlling display of pixels of a display screen according to an amount of folding includes: and if the folding direction is along the second folding direction, controlling the pixels of at least two adjacent rows in the non-folding area, which are in the same direction as the folding axis, to be combined into a row of pixels for image display.

In this embodiment, as shown in fig. 13, fig. 13 provides a schematic diagram of a display screen folding information structure. In the display screen, when the display screen is folded in the second direction, namely, the display screen is folded towards the B surface. At this time, the surface on the a-plane side of the pixel at the folding region 10 is stretched to be deformed so that the light transmission area of the single pixel at the region is larger than the light transmission area of the single pixel at the non-folding region 20, thereby causing a difference in screen display between the folding region 10 and the non-folding region 20. As the folding amount R gradually increases, the picture display difference becomes larger, and when the folding amount R is larger than the preset threshold, the picture of the folding area 10 is significantly stretched (i.e., the picture size displayed by a single pixel in the folding area 10 is at least twice as large as that in the non-folding area 20). At this time, the terminal performs differential adjustment on the pixel display of the folded region 10 and the non-folded region 20, that is, controls the pixels in at least two adjacent rows in the non-folded region 20, which are in the same direction as the folding axis, to be merged into one row, and performs image display.

Fig. 14 is a flowchart of a pixel display control method of a display panel according to another embodiment, and as shown in fig. 14, the method includes controlling pixels of at least two adjacent rows in the non-folding area, which are in the same direction as the folding axis, to merge into a row of pixels for image display, including step S1402 and step S1408.

Step S1402: if the pixels along the direction of the folding axis share the same scanning electrode, controlling the scanning electrodes of at least two adjacent rows in the non-folding area, which are in the same direction as the folding axis, to simultaneously output scanning signals;

step S1404: controlling data signals output by the data electrodes in the non-folding area to enable the display contents of the pixels in at least two adjacent rows to be combined into pixels in one row for display;

step S1406: if the pixels along the direction of the folding axis use a scanning electrode respectively, controlling the data signals output by the data electrodes in the non-folding area to enable the display contents of the pixels in at least two adjacent columns to be combined into the pixels in one column for display;

It will be appreciated that the difference between folding the display screen in the second direction and folding the display screen in the first direction is whether the pixel light transmissive side of the fold area 10 is stretched or compressed. Therefore, when the display panel is folded in the second direction, the terminal drives the pixels of the folding area 10 in the same manner as the pixels of the non-folding area 20 when the display panel is folded in the first direction; the terminal drives the non-folding area 20 in the same way as the folding area 10 when the display panel is folded in the first direction. And will not be described in detail herein.
