[0064] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0068] Hereinafter, related terms in the embodiments of the present disclosure are described.

[0069] An organic light-emitting diode (OLED) is a display technology that uses organic semiconductor materials and light-emitting materials to emit light under the drive of an electric field through carrier injection and recombination.

[0070] General-purpose input / output (GPIO) is a pin interface on display driver chips or related control chips. It can be configured as input or output mode through software, used for simple data interaction and control signal transmission with external devices. For example, in a display system, GPIO can be used to connect external devices such as buttons and sensors to detect user input or collect environmental information, and then control the display content accordingly.

[0071] I2C (Inter-Integrated Circuit) is a serial communication bus protocol. In display screen technology, it is commonly used for communication between display driver chips and host controllers. I2C bus only needs two lines (serial data line and serial clock line) to realize data transmission between devices, with the advantages of fewer interface lines, simple control mode, and higher communication efficiency. Through the I2C bus, the host controller can send control commands and display data to the display driver chip to realize parameter setting, display content updating, and other operations on the display screen.

[0072] VH (Voltage High) represents the voltage value of the logic high level. In display driving circuits, digital signals usually represent different logic states with high and low levels. In some scenarios, when VH is high, the corresponding electronic device can be turned on or off.

[0073] Source start pulse (STV) is an important control signal of the source driver circuit in liquid crystal display driving, used to indicate the source driver to start outputting the data voltage corresponding to a row of pixels. It cooperates with the gate drive signal to ensure that the pixel data can be accurately written into each pixel unit of the display panel according to the timing, and is one of the key signals of display driving timing control.

[0074] In embodiments of the present disclosure, the electronic device can be a device equipped with a flexible OLED display screen, capable of running multiple functions, such as a mobile phone, a tablet computer, a wearable device, etc.

[0075] The related technologies involved in the embodiments of the present disclosure are described below.

[0076] In some applications, flexible displays based on OLED technology are used in many electronic products. Because one side of a flexible display can be bent or rolled up, the driver circuit board is generally placed on the non-bending / rolling side, thus limiting the improvement of display performance parameters such as resolution and refresh rate. Please refer to the following explanation for details.

[0077] Figure 1A The illustration shows one of the scenario diagrams of a driver circuit board configuration according to an embodiment of the present disclosure.

[0078] like Figure 1A As shown, the electronic device in the figure has a resolution of 2880×1800 and a refresh rate of 165Hz. If the driver circuit board 110 is positioned on the long side of the electronic device's display screen, and the display screen is driven using a line scanning method, then the scanning time for each row of pixels on the display screen is... It can be calculated as follows: =1 / 165 / (1800+blank lines).

[0079] Figure 1B The illustration shows a second scenario diagram of a driver circuit board configuration according to an embodiment of the present disclosure.

[0080] like Figure 1B As shown, the electronic device in the figure has a resolution of 1800×2880 and a refresh rate of 165Hz. If the long side of the electronic device's display screen can be bent or folded, the driver circuit board 110 needs to be positioned on the short side of the display screen. When driving the display screen, a line scanning method is used to drive the display panel. The scanning time for each row of pixels on the display screen is... It can be calculated as follows: =1 / 165 / (2800+blank rows). Therefore, for the same electronic device, while keeping the performance parameters (screen refresh rate) of the display screen unchanged, changing the driver circuit board from the long side to the short side of the display screen will result in a reduction in the scanning time of each row of pixels on the display screen.

[0081] Figure 2 The illustration schematically shows the relationship between pixel charging time and the change in voltage difference between pixels according to an embodiment of the present disclosure.

[0082] Since the scanning time of each row of pixels on the display screen is the same as the charging time of each row of pixels when the data is written; for example Figure 2 As shown, the charging time is from Down to At that time, the voltage difference between each pixel is determined by Δ increases to Δ When the scanning time of each row of pixels is shortened, the charging time of each row of pixels when the data voltage is written will also be shortened, which makes the voltage difference between each pixel in the display panel increase, thereby causing the optical performance of the display screen to deteriorate, such as flickering.

[0083] To solve the problems in the related art, embodiments of the present disclosure provide a display control method, including: determining a use mode of an electronic device, wherein the size parameter and / or display brightness of the available display area of the display screen of the electronic device are different in different use modes; and controlling the display refresh rate of the available display area of the display screen based on the use mode, wherein the display refresh rate of the available display area is different in different use modes.

[0084] By using the above method, the difference in the size parameter and / or display brightness of the available display area of the display screen of the electronic device in different use modes is determined, and the display refresh rate of the available display area is controlled accordingly, so that it is different in different use modes. Further, the problems of changes in the scanning time of each row of pixels due to the change in the position of the driving circuit board, and further shortening of the pixel charging time, increasing of the voltage difference, and deterioration of the optical performance are effectively avoided. At the same time, in the case where the performance parameters of the flexible display screen are affected by the limited position of the driving circuit board, the display refresh rate is flexibly adjusted according to different use scenarios, which not only meets the user's display needs in various scenarios, but also guarantees the optical performance of the display screen, and improves the user's visual experience.

[0085] Figure 3 A flowchart of a display control method according to an embodiment of the present disclosure is schematically shown.

[0086] As shown in Figure 3 The display control method at least includes steps S301-S302.

[0087] In operation S301, the use mode of the electronic device is determined, wherein the size parameter and / or display brightness of the available display area of the display screen of the electronic device are different in different use modes.

[0088] In the embodiments of the present disclosure, the use mode of the electronic device refers to the use state of the electronic device under certain conditions; wherein the transformation conditions of the use mode include but are not limited to: the transformation of the body form of the electronic device, the transformation of the application running in the electronic device, and the transformation of the control instruction received by the electronic device; when any one or more of the above transformation conditions occurs, it can be determined that the use mode of the electronic device changes.

[0089] In embodiments of the present disclosure, the available display area refers to a screen area in the display screen that can be used to show a visual picture to a user when the electronic device is in a certain use mode; wherein when the available display area only includes a partial area of the display screen, other areas of the display screen except the available display area are in a screen-off state or a sleep state by default.

[0090] Specifically, when the display screen of the electronic device is in a first use mode, the available display area of the display screen can be the entire area of the display screen; when the display screen of the electronic device is in a second use mode, the available display area of the display screen can be a first area of the display screen, at this time, a second area of the display screen except the first area is in a screen-off state or a sleep state, at this time, the size parameters of the available display area in the first use mode and the second use mode are different. The size parameters include size, aspect ratio (aspect ratio determines whether to display horizontally or vertically), etc.

[0091] Further, when the display screen of the electronic device is in a third use mode, the available display area of the display screen can be the entire area of the display screen; at the same time, the screen brightness of the display screen is reduced from a first brightness to a second brightness.

[0092] Operation S302, control the display refresh rate of the available display area of the display screen based on the use mode, wherein the display refresh rate of the available display area is different in different use modes.

[0093] Specifically, based on the use mode in which the electronic device is currently located, the display refresh rate of the available display area can be determined. Wherein in different use modes, when the body form of the electronic device changes, the hardware indicators related to the display refresh rate in the electronic device are also different.

[0094] Illustratively, one side of the display screen of the electronic device can be folded or curved, when the display screen is fully unfolded, it is in a first use mode; at this time, each row of pixels on the side of the display screen that can be folded or curved collectively constitutes the available display area, wherein the number of pixel rows is a first number. When the display screen is folded or curved, it is converted from the first use to the second use mode; at this time, the display screen can be divided into at least two flat screens, at least one flat screen is determined from the at least two flat screens as the displayable area; at this time, each row of pixels in the displayable area that is on the same side as the side of the display screen that can be folded or curved collectively constitutes the available display area, wherein the number of pixel rows is a second number.

[0095] Further, when the electronic device is converted from the first use mode to the second use mode, the number of pixel rows is reduced from the first number to the second number; at this time, without reducing the charging time of each row of pixels, the display screen refresh rate can be increased from a first refresh rate to a second refresh rate.

[0096] In embodiments of the present disclosure, when the use mode of the electronic device changes, the display direction of the display screen of the electronic device can also be controlled to change.

[0097] According to embodiments of the present disclosure, in operation S302, controlling the display refresh rate of the available display area of the display screen based on the use mode comprises operations S3021-S3023.

[0098] Operation S3021, determining the target driving circuit corresponding to the use mode from the driving circuits of the display screen.

[0099] In embodiments of the present disclosure, the driving circuit of the display screen is used to receive and decode the image data signal from the display controller, convert the digital instruction into an analog voltage or current signal, and drive the light emitting element in each pixel of the display screen to work.

[0100] Specifically, the driving circuit is composed of a plurality of driving sub-circuits, wherein each driving sub-circuit is used to drive and control a corresponding row of pixels in the display screen; after determining the use mode of the electronic device, each row of pixels constituting the available display area can be determined, and then each driving sub-circuit corresponding to each row of pixels is determined, and each driving sub-circuit finally constitutes part of the target driving circuit.

[0101] Operation S3022, controlling the enable state of the target driving circuit to control the available display area of the display screen to have the target refresh rate.

[0102] In embodiments of the present disclosure, the enable state of the driving circuit includes two states of open enable and close enable, and by controlling the enable state, whether the driving circuit drives the corresponding display area can be controlled.

[0103] Specifically, after determining the use mode of the electronic device, the working state of the target driving circuit corresponding to the driving circuit and the use mode is adjusted to open enable, and the working state of other circuits in the driving circuit except the target driving circuit is adjusted to close enable. Further, the driving circuit in the electronic device is only used to drive the displayable area in the display screen.

[0104] Operation S3023, controlling the target driving parameter of the target driving circuit to control the available display area of the display screen to have the target refresh rate.

[0105] In embodiments of the present disclosure, the target driving parameter is used to adjust the control signal of the output of the target driving circuit, such as adjusting the scan pulse signal output by the target driving circuit.

[0106] For example, the STV signal is used to control the simultaneous conduction of multiple rows of pixels, to realize parallel scanning of the available display area, thereby improving the display refresh of the available display area. In a pulse period of an STV signal, multiple vertical clock signals are sent to multiple rows of pixels in parallel; for example, in a pulse period of an STV signal, one vertical clock signal is sent to each of two rows of pixels, so that the two rows of pixels are simultaneously refreshed, thereby reducing the refresh time of all pixels in the available display area by half, thereby doubling the display refresh rate of the available display area.

[0107] According to an embodiment of the present disclosure, in operation S3022, the enable state of the target drive circuit is controlled, including operation S3022A to operation S3022C.

[0108] In operation S3022A, the available display area of the display screen is determined based on the use mode.

[0109] Specifically, the available display area of the display screen is determined based on the use mode of the electronic device. Different use modes will result in different available display areas of the display screen, which can be the entire display screen or part of the display area, i.e., in addition to determining the size of the available display area, the aspect ratio or resolution information of the available display area can be further determined.

[0110] In operation S3022B, when the available display area is the entire display area of the display screen, the entire drive circuit of the display screen is controlled to be in an enabled state to control the display screen to have a first refresh rate.

[0111] Specifically, if the available display area is the entire display area of the display screen, it means that the entire screen needs to be used for display in the current use mode. At this time, the entire drive circuit of the display screen is controlled to be in an enabled state, so that all drive circuits are working together to drive the entire screen to display, thereby making the display screen have a first refresh rate. For example, when the electronic device is in a normal desktop browsing mode, the entire screen is used for display, at this time all drive circuits are enabled, and the screen displays at a first refresh rate, such as 60Hz, to meet the user's visual demand for browsing.

[0112] In operation S3022C, when the available display area is part of the display area of the display screen, the first drive circuit corresponding to the part of the display area is controlled to be in an enabled state, and the other drive circuits of the display screen are controlled to be in a non-enabled state, to control the available display area to have a second refresh rate; wherein the second refresh rate is greater than the first refresh rate.

[0113] Specifically, if the available display area is a partial display area of the display screen, i.e., only a partial screen area is needed for display in the current use mode. At this time, the first drive circuit corresponding to the partial display area is controlled to be in an enabled state, and other drive circuits of the display screen are controlled to be in a disabled state. Among them, only the first drive circuit in the enabled state drives the corresponding partial display area to display, in this way, the available display area has a second refresh rate. Since the number of pixels in the partial display area is relatively small, a higher refresh rate can be achieved under the same charging time of each row of pixels, so the second refresh rate is greater than the first refresh rate. For example, when the electronic device changes from an unfolded state to a folded state, only the middle part of the folded screen is used as the available display area, or in a specific video playing mode of the electronic device, in order to highlight the video content, only the middle part of the screen can be used as the available display area, at this time, the first drive circuit corresponding to the part is enabled, and other drive circuits are disabled, the partial display area can be displayed at a higher second refresh rate, such as 120Hz, to improve the smoothness of video playing.

[0114] The embodiment of the present disclosure also provides a control circuit for controlling the drive circuit of the display screen.

[0115] Figure 4A One of the principle schematic diagrams of a display control method according to an embodiment of the present disclosure is schematically shown.

[0116] As shown in Figure 4A When the first control signal is on, the first path is turned on, and the controller 1 and the controller 2 can both receive the STV signal, and then drive the display area 410 and the display area 420 to work together as the available display area. At this time, the second control signal is off, and the second path is not turned on.

[0117] When the second control signal is on, the second path is turned on, and the controller 2 can receive the STV signal, while the controller 1 receives the VH signal and is turned off. At this time, only the display area 420 in the display screen can be driven to work by the drive circuit, and then the display area 420 is used as the available display area. Among them, when the available display area changes from the display area 410 and the display area 420 to the display area 420, the number of pixel rows of the available display area is reduced.

[0118] The embodiment of the present disclosure also provides another control circuit for controlling the drive circuit of the display screen.

[0119] Figure 4B The second principle schematic diagram of a display control method according to an embodiment of the present disclosure is schematically shown.

[0120] In some scenarios, the first and second control signals can control more controllers to achieve control of multiple display areas. For example... Figure 4B As shown, display areas 410 and 430 are respectively configured on both sides of display area 420. When the first control signal is turned on, controllers 1, 2, and 3 can all receive the STV signal, thereby driving display areas 410, 420, and 430 to work together as available display areas. At this time, the second control signal is turned off, and the second path is not connected.

[0121] When the second control signal is activated, the second path is turned on, and controller 2 can receive the STV signal. Simultaneously, controllers 1 and 3 are turned off after receiving the VH signal. At this time, the driving circuit in the display screen can only drive display area 420 to work, thus making display area 420 a usable display area. Specifically, when the usable display area changes from display area 410, display area 420, and display area 430 to display area 420, the number of pixel rows in the usable display area decreases.

[0122] Figure 4C The schematic diagram illustrates one of the schematic principles of a drive circuit according to an embodiment of the present disclosure.

[0123] In the embodiments of this disclosure, SCAN 1 to SCAN n represent different scanning sequences or scanning steps, scanning the available display area from top to bottom according to a predetermined timing sequence so that the available display area is in a display state.

[0124] Figure 4D The schematic diagram illustrates a second schematic diagram of a driving circuit according to an embodiment of the present disclosure.

[0125] For example, in Figure 4B In this context, when the available display area comprises all of display areas 410, 420, and 430, the SCAN signal can start from the first row of pixels in display area 410 and scan downwards row by row according to a predetermined timing (1H) until the last row of pixels in display area 430. Here, 1H time = 1 frame time / (total number of rows of pixels in the available display area + number of blank rows).

[0126] In embodiments of this disclosure, the number of pixel scan lines in portrait mode is greater than the number of pixel scan lines in landscape mode; that is, 1 hour in portrait mode will be less than 1 hour in landscape mode.

[0127] According to an embodiment of this disclosure, in operation S3023, the target driving parameters of the target driving circuit are controlled, including operations S3023A to S3023B.

[0128] Operation S3023A, determining the available display area of the display screen and the second driving circuit corresponding to the available display area based on the use mode.

[0129] In embodiments of the present disclosure, the second driving circuit is determined based on the available display area.

[0130] For example, in the case where the available display area includes only the second display area 420, the second driving circuit is composed of each driving sub-circuit corresponding to each row of pixels in the second display area 420. Figure 4A For example, in the case where the available display area includes only the second display area 420, the second driving circuit is composed of each driving sub-circuit corresponding to each row of pixels in the second display area 420.

[0131] For example, in the case where the available display area includes only the second display area 420, the second driving circuit is composed of each driving sub-circuit corresponding to each row of pixels in the second display area 420. Figure 4B For example, in the case where the available display area includes only the second display area 420, the second driving circuit is composed of each driving sub-circuit corresponding to each row of pixels in the second display area 420.

[0132] Each driving sub-circuit is used to drive and control a corresponding row of pixels in the display screen.

[0133] Operation S3023B, based on the use mode, controlling the number of vertical clock pulses in the scanning pulse signal of the second driving circuit to control the available display area to have a target refresh rate.

[0134] Specifically, after determining the second driving circuit based on the use mode, the number of vertical clock pulses in the scanning pulse signal of the second driving circuit is controlled to adjust the available display area to have a target refresh rate. The vertical clock pulses in the scanning pulse signal are related to the scanning in the vertical direction of the screen, and by adjusting the number of vertical clock pulses, the scanning speed of the screen can be changed, and thus the display refresh rate can be controlled.

[0135] For example, when the electronic device is in the first use mode, the requirement for the refresh rate is relatively low, at this time, the number of vertical clock pulses in the scanning pulse signal of the second driving circuit can be appropriately reduced, so that the available display area has a relatively low target refresh rate, which can meet the normal needs of the user and reduce power consumption; when the electronic device switches to the second use mode (such as when the user wants to run a large 3D game in the second use mode), in order to present a smooth graphics picture, the number of vertical clock pulses needs to be increased to increase the refresh rate of the available display area, so as to meet the high requirement of the game on the smoothness of the picture. Through precise control of the number of vertical clock pulses, the purpose of flexibly adjusting the display refresh rate according to different use modes is achieved.

[0136] In embodiments of the present disclosure, by simultaneously adjusting the pulse period of the scanning pulse signal and the number of vertical clock pulses in the scanning pulse signal, more diverse adjustments of the display resolution of the available display area can be achieved.

[0137] Figure 5 Fig. 2 schematically shows a flowchart of a display control method according to an embodiment of the present disclosure.

[0138] In operation S301, according to embodiments of the present disclosure, the use mode of the electronic device is determined, including at least one of operations S501-S504.

[0139] In operation S501, the use mode of the electronic device is determined based on a device form change of the electronic device, different device forms correspond to different use modes, and the device form change includes at least one of an angle change between different display areas of the display screen, a size change of the display area, or a display direction change of the display area determined based on a sensor.

[0140] In embodiments of the present disclosure, the device form change can be a change in the physical form of the electronic device as a whole or the display screen, which can be perceived and identified in a specific way, and then used as a basis for determining the use mode.

[0141] Specifically, the form change of the electronic device can reflect the change of its use scenario, and then correspond to different use modes. The state change of the display screen, such as the angle change between different display areas, is perceived by the sensor; for example, on an electronic device with a folding screen, when the screen is folded to a certain angle, it can be determined to enter a specific use mode.

[0142] Specifically, the size change of the display area can be a change in the display area on the physical level, or a change in the display area on the non-physical level. For the change in the display area on the physical level; for example, for a device with a stretchable screen, when the screen is stretched to make the display area larger, it can enter a large-screen display mode, and when the screen is rolled up to make the display area smaller, it can enter a small-screen display mode. For the change in the display area on the non-physical level, the brightness of each pixel in the display screen is adjusted by controlling the pixel data input to the display area, and then the size of the display area changes.

[0143] Specifically, when the display direction changes, i.e., the electronic device can change from a vertical screen to a horizontal screen, and then switch to different application use modes, such as a horizontal screen suitable for watching video and audio, and a vertical screen suitable for single-handed browsing of application information.

[0144] In operation S502, a use mode of the electronic device is determined based on a target configuration parameter input by a target user, the configuration parameter being used to configure a size parameter of an available display area of a display screen and / or a display brightness.

[0145] Specifically, the sensor of the electronic device can acquire voice input, gesture control or text input of the target user to determine the target configuration parameter, and further determine the use mode of the electronic device. In other embodiments, text data input by the user or other parameters used to configure the display size, display brightness, whether to split the screen, display brightness, etc. can be acquired through a specific application interface to switch the use mode of the display screen.

[0146] For example, the user can control the display state of a part of the display screen to change by sliding or clicking a specific area of the display screen, so as to change the available display area.

[0147] In operation S503, the use mode of the electronic device is determined based on application running information of the electronic device and / or environmental data of a current space environment.

[0148] In embodiments of the present disclosure, the application running information can be related information of an application program running on the electronic device, such as application type, running state, etc., which can assist in determining the use mode of the electronic device.

[0149] In embodiments of the present disclosure, the environmental data of the space environment can be various data of the space environment where the electronic device is currently located, such as light intensity, temperature, humidity, etc., which can affect the selection of the use mode of the device, such as different brightness corresponding to different refresh rates, and different temperatures corresponding to different refresh rates (temperature can affect the response speed of liquid crystal deflection).

[0150] Specifically, the type of the application program running on the electronic device, the running state, and other application running information, as well as the environmental data of the current space environment, can help determine the use mode. For example, when it is detected that the device is running a game application (application running information) and the environmental light is strong (environmental data), it can be determined to enter a game strong light mode, at which time the brightness and refresh rate of the available display area of the display screen can be increased to meet the visual requirements of the game in a strong light environment. For another example, when a music playing application is running and the environment is quiet, the screen brightness and refresh rate can be reduced to enter a music playing low power consumption mode.

[0151] In embodiments of the present disclosure, the use mode of the electronic device can also be determined based on the target configuration parameter input by the target user, and the application running information of the electronic device and / or the environmental data of the current space environment.

[0152] Operation S504 determines the usage mode of the electronic device based on the relative positional relationship between the display screen of the electronic device and the target input device.

[0153] In the embodiments of this disclosure, the target input device may be an input device that interacts with the display screen of an electronic device, including but not limited to electronic products such as a mouse, keyboard, stylus, and touchpad.

[0154] Specifically, the positional relationship between the display screen and the target input device adjusts the usage mode of the electronic device under certain conditions, thereby adjusting the available display area of ​​the display screen. For example, in foldable screen products, if the screen is obstructed by the keyboard, the available display area can be limited to the unobstructed area, and the obstructed area can enter a black screen or power-off mode.

[0155] Figure 6 The third schematic diagram illustrates the principle of a display control method according to an embodiment of the present disclosure.

[0156] For example, such as Figure 6 As shown, the display screen of the electronic device includes a rotatably connected display area 610 and display area 620. When the display screen of the electronic device is in the unfolded state, there is no spatial contact between the wireless keyboard 630 and the display screen. The wireless keyboard 630 is connected to the electronic device through communication, allowing the user to control the electronic device using the wireless keyboard 630. When the display area 610 and display area 620 are rotated to a certain angle, the wireless keyboard 630 can be placed in the display area 620. At this time, the usage mode of the electronic device changes from tablet mode to laptop mode, and the available display area changes to display area 610.

[0157] It should be noted that the aforementioned wireless keyboard 630 can be replaced by other devices such as touchpads, tablets, and mobile phones. Furthermore, in some scenarios, when the display screen of an electronic device is unfolded and the wireless keyboard 630 is placed in the display area 620, the usage mode of the electronic device can be determined based on at least one of the following: target configuration parameters input by the target user, application operation information of the electronic device, and environmental data of the current spatial environment. This allows for the adjustment of the available display area of ​​the screen.

[0158] According to embodiments of this disclosure, in operation S302, controlling the display refresh rate of the available display area of ​​the display screen based on the usage mode includes at least one of operations S3021 to S3026:

[0159] In operation S3021, in a case where the display screen of the electronic device is switched from the first mode to the second mode, all the drive circuits of the display screen are controlled to be in an enabled state to control the available display area of the display screen to have a first refresh rate, and the size of the available display area of the display screen in the second mode is greater than the size of the available display area in the first mode.

[0160] Specifically, when the display screen of the electronic device is switched from the first mode to the second mode, since the size of the available display area in the second mode is greater than the size of the available display area in the first mode, to ensure that the entire enlarged available display area can be normally displayed, all the drive circuits of the display screen are controlled to be in the enabled state, so that the available display area of the display screen has the first refresh rate. For example, for a foldable-screen mobile phone, when the screen is unfolded from the folded state (first mode) to the tablet mode (second mode), the available display area of the screen is enlarged, and at this time, all the drive circuits are enabled, and the screen displays at the first refresh rate (such as 60 Hz), thereby meeting the basic needs of users for large-screen content browsing and the like.

[0161] In operation S3022, in a case where the display screen of the electronic device is switched from the second mode to the first mode, the first drive circuit of the display screen is controlled to be in the enabled state, and other drive circuits of the display screen are controlled to be in the disabled state, to control the available display area of the display screen to have a second refresh rate, and the second refresh rate is greater than the first refresh rate.

[0162] Further, when the display screen is switched from the second mode back to the first mode, to achieve smoother display effect in the smaller available display area, the first drive circuit of the display screen is controlled to be in the enabled state, and other drive circuits are controlled to be in the disabled state, so that the available display area of the display screen has the second refresh rate, and the second refresh rate is greater than the first refresh rate. For example, when the above foldable-screen mobile phone is folded from the tablet mode back to the mobile phone mode, only the first drive circuit for controlling the smaller available display area is enabled, and other drive circuits are disabled, and the smaller area displays at the second refresh rate (such as 90 Hz) to improve the smoothness of operation.

[0163] In operation S3023, in a case where the display screen of the electronic device is switched from the horizontal screen state to the vertical screen state, the display refresh rate of the display screen is controlled to be switched from a third refresh rate to a fourth refresh rate, and the third refresh rate is different from the fourth refresh rate.

[0164] Specifically, when the display screen of the electronic device is switched from the horizontal screen state to the vertical screen state, according to different display requirements of the horizontal screen and the vertical screen and user operation scenarios, the display refresh rate of the display screen is controlled to be switched from the third refresh rate to the fourth refresh rate.

[0165] Further, the vertical clock controls the scanning frequency in the vertical direction of the screen. In each vertical scanning period, the number of vertical clocks determines the time required to scan a row of pixels and the total time required to complete a frame of image scanning, thereby affecting the refresh rate. A higher vertical clock frequency (i.e., a larger number of pulses per unit time) means a faster scanning speed, which can achieve a higher refresh rate. In the horizontal screen and vertical screen states, the number of pixel rows of the display screen changes. Generally, in the horizontal screen state, the number of horizontal direction pixels is large, and the number of vertical direction pixel rows is relatively small; in the vertical screen state, the number of horizontal direction pixels is small, and the number of vertical direction pixel rows is relatively large. To ensure that the refresh rate is maintained or improved in the vertical screen state, the number of vertical clocks needs to be adjusted according to the change in the number of pixel rows in the horizontal and vertical screen states. For example, in the horizontal screen state, a first number of vertical clocks is set in each vertical scanning period to achieve a third refresh rate. When switching to the vertical screen state, the number of vertical clocks needs to be increased to maintain or improve the refresh rate due to the increase in the number of pixel rows. Assuming that a second number of vertical clocks is set in each vertical scanning period to achieve a fourth refresh rate in the vertical screen state, and the second number is greater than the first number. When it is detected that the display screen switches from the horizontal screen to the vertical screen state, the clock generator or related control logic of the display screen is adjusted to increase the number of vertical clocks.

[0166] For example, when a user switches a foldable tablet from a horizontal screen for watching a video (the third refresh rate is set to 60 Hz) to a vertical screen for viewing messages, the refresh rate is switched to a fourth refresh rate (e.g., 90 Hz) to adapt to the characteristics of the vertical screen operation and content display, so that the vertical screen interface sliding operation is smoother.

[0167] It should be noted that in some scenarios, the adjustment of the refresh rate also needs to consider factors such as the pixel scanning speed, the performance of the display controller, and the target value of the refresh rate.

[0168] In operation S3024, in a case where the display screen of the electronic device enters the split-screen mode, the display refresh rate of the target split-screen area is controlled based on the size parameter and / or the display brightness of the target split-screen area.

[0169] For example, when the electronic device enters the split-screen mode and displays a video and a document at the same time, if the size of the target split-screen area where the video is located is large and the user wants a better video viewing experience, the display refresh rate of the area can be appropriately increased; if the brightness of the document area is low and the requirement for the refresh rate is not high, a relatively low refresh rate can be set.

[0170] In operation S3025, in a case where the electronic device switches from running a first application to running a second application, the available display area of the electronic device is controlled to switch from a fifth refresh rate to a sixth refresh rate, and the fifth refresh rate is different from the sixth refresh rate. The available display areas corresponding to the first application and the second application are the same or different.

[0171] Specifically, when the electronic device switches from running a first application to running a second application, due to different requirements of different applications for display, the available display area of the electronic device is switched from a fifth refresh rate to a sixth refresh rate, and the fifth refresh rate is different from the sixth refresh rate; wherein the available display area corresponding to the first application and the second application can be the same or different.

[0172] For example, switching from running a reading application (first application, the fifth refresh rate is set to 30Hz to save power) to running a game application (second application), the game requires smoother pictures, so the refresh rate of the available display area is switched to a sixth refresh rate (such as 120Hz) to meet the high requirements of the game for display smoothness. If the interface of the game application requires a larger display area than the interface of the reading application, the area of the available display area increases at this time.

[0173] Operation S3026, in the case of switching to a target occlusion relationship between the target input device and the display screen of the electronic device, the non-occluded area of the display screen is switched from a seventh refresh rate to an eighth refresh rate, and the eighth refresh rate is greater than the seventh refresh rate.

[0174] For example, as shown in Figure 6 The wireless keyboard 630 can be placed in the display area 620, at which time the use mode of the electronic device is changed from a tablet mode to a notebook mode, and the available display area is changed to the display area 610. At the same time, based on the change of the use mode of the electronic device, the display refresh rate of the non-occluded area of the display screen (i.e. the display area 610) is increased from the seventh refresh rate to the eighth refresh rate; wherein the way of increasing the display refresh rate can refer to the specific description of operation S302.

[0175] According to an embodiment of the present disclosure, in operation S302, the display refresh rate of the available display area of the display screen is controlled based on the use mode, further comprising at least one of operation S3021~operation S3022.

[0176] Operation S3021, obtaining target reference data, controlling the display refresh rate of the available display area based on the target reference data and the use mode, the target reference data including at least one of user portrait data of a target user, configuration information of the display screen of the electronic device, and environmental data of the space environment in which the electronic device is located.

[0177] In an embodiment of the present disclosure, the target reference data is related data for assisting in controlling the display refresh rate of the available display area of the display screen, including one or more of user portrait data of a target user, configuration information of the display screen of the electronic device, and environmental data of the space environment in which the electronic device is located.

[0178] Specifically, after the use mode of the electronic device changes, further target reference data is acquired, when the target reference data meets certain conditions, it is determined to adjust the display refresh rate of the electronic device based on the change of the use mode; when the target reference data does not meet certain conditions, after the use mode changes, the display refresh rate of the electronic device can not be adjusted within a predetermined time, or the adjustment is directly stopped.

[0179] In an embodiment of the present disclosure, the user portrait data can be a data set describing the characteristics of the target user, such as the user's age, gender, usage habits, preference settings, etc. By analyzing the user portrait data, the potential needs of the user for display effects can be understood, so that the display refresh rate can be more accurately controlled.

[0180] For example, when the target reference data includes user portrait data of the target user, for example, the user portrait of the target user shows that he often runs high-frame-rate games in the electronic device. When the electronic device detects that the target user opens a game application and enters a game use mode, the display refresh rate of the available display area of the display screen is increased based on the user's preference for high-frame-rate display, the user portrait data, and the game use mode, to meet the user's demand for smooth game pictures.

[0181] In an embodiment of the present disclosure, the configuration information of the display screen can be parameter settings and characteristic descriptions about the display screen of the electronic device itself, including the change mode of the display refresh rate when it changes and the change range of the refresh rate when it changes, and the change time of the refresh rate, etc. The change mode of the display refresh rate when it changes includes gradient change, random change and direct change, and the configuration information of the display screen determines the adjustment range of the refresh rate that the display screen can achieve in different use modes.

[0182] For example, when the target reference data includes configuration information of the display screen of the electronic device, if the highest refresh rate supported by the display screen of the electronic device is 120Hz, when the electronic device switches from the normal office mode (the current refresh rate is 90Hz) to the video editing mode, the configuration information of the display screen indicates that the change gradient of the refresh rate is 5Hz / time, and the interval time of each change is 0.05s. At this time, based on the above configuration information, the refresh rate is increased to 90Hz or 120Hz to optimize the display effect.

[0183] In an embodiment of the present disclosure, the environment data of the space environment can be various environmental factor data of the space where the electronic device is located, such as light intensity, temperature, humidity, etc.; wherein the environmental factors can affect the user's visual perception of the screen display, and further affect the configuration result of the display refresh rate.

[0184] In operation S3022, the change information of the display refresh rate of the available display area is determined based on the change of the use mode, the corresponding gradient adjustment parameter is determined based on the change information, and the electronic device is controlled to sequentially adjust from the current refresh rate to the target refresh rate corresponding to the changed use mode based on the gradient adjustment parameter, wherein the gradient adjustment parameter is used to control at least the single adjustment range of the display refresh rate.

[0185] In the embodiments of the present disclosure, the change information of the display refresh rate is used to reflect the relevant information that needs to be changed due to the change of the use mode, including the content that the refresh rate needs to be increased or decreased, and the range of the change; wherein the change information of the display refresh rate is the basis for determining the gradient adjustment parameter.

[0186] In the embodiments of the present disclosure, the gradient adjustment parameter is used to control the parameter of the display refresh rate adjustment process, which determines the single adjustment range of the display refresh rate. By determining the gradient adjustment parameter, the display refresh rate can be smoothly transitioned when the use mode is converted, and the impact on the user's vision caused by the sudden change of the refresh rate can be avoided.

[0187] For example, when the target user is reading an electronic book using the portrait mode of the electronic device. In the portrait reading mode, in order to save power, a high refresh rate is usually not needed, and the current display refresh rate is set to 30Hz. When the electronic device is changed from the portrait mode to the landscape mode, and the target user opens a video application to start watching a video, the phone detects that the use mode is switched from the portrait reading mode to the landscape video mode. According to the gradient adjustment parameter determined in the change information of the display refresh rate, and the demand of the landscape video mode for the smoothness of the picture, the refresh rate is gradually increased from 30Hz to 90Hz suitable for video playing. Wherein, the gradient adjustment parameter represents that the time interval of each refresh rate change is at least 100 milliseconds, and the gradient adjustment range of each time is 15Hz. At this time, the display refresh rate will change as follows: 100 milliseconds after detecting the mode switching, the refresh rate is increased from 30Hz to 45Hz; 100 milliseconds later, from 45Hz to 60Hz. 100 milliseconds later, from 60Hz to 75Hz; and 100 milliseconds later, from 75Hz to 90Hz.

[0188] The present disclosure adjusts the display refresh rate based on the gradient change, which meets the demand of the use mode for the refresh rate, and also avoids the impact on the user's vision caused by the sudden change of the refresh rate.

[0189] Figure 7 Fig. 3 shows a flowchart of a display control method according to an embodiment of the present disclosure.

[0190] According to the embodiments of the present disclosure, as Figure 7As shown, the display control method further includes operation S700 of controlling the cathode voltage of the display screen to be adjusted to a target voltage value corresponding to the use mode.

[0191] In embodiments of the present disclosure, the cathode voltage is a voltage applied to the cathode of the driving circuit of the display screen, and the cathode voltage is used to adjust the display effect of the display screen, such as brightness, color, etc. In different use modes, the cathode voltage needs to be adjusted to optimize the display performance.

[0192] According to embodiments of the present disclosure, as Figure 7 As shown, in operation S700, controlling the cathode voltage of the display screen to be adjusted to a target voltage value corresponding to the use mode includes at least one of operation S701 to operation S703.

[0193] Operation S701, in response to the electronic device switching from a current first use mode to a target use mode, controlling the cathode voltage of the display screen to be adjusted from a current first voltage value to a target voltage value corresponding to the target use mode, wherein the first voltage value is greater than or less than the target voltage value, and the size parameter of the available display area in the first use mode is different from the size parameter in the target use mode.

[0194] Specifically, when the electronic device switches from the current first use mode to the target use mode, the size parameter of the available display area changes; after the size parameter of the available display area changes, the display refresh rate of the available display area is adjusted by adjusting the cathode voltage of the display screen. In some use mode change processes, the display brightness of the available display area can also be adjusted at the same time.

[0195] Operation S702, based on the use mode, controlling the power supply module of the electronic device to output a number of pulses to the display screen to adjust the cathode voltage of the display screen to the target voltage value.

[0196] In embodiments of the present disclosure, the power supply module is a component in the electronic device responsible for providing power to the display screen, including but not limited to TCON (timing controller), PMIC (power management chip), PD Controller (power distribution controller) directly supplying power to the screen, and independent power supply in the screen independent power supply scenario. The power supply module adjusts the cathode voltage of the display screen by outputting different number of pulses to adapt to the needs of the display screen in different use modes.

[0197] Operation S703, obtaining target reference information of the electronic device in the target use mode, and based on the target reference information, controlling the cathode voltage of the display screen to be adjusted to the corresponding target voltage value.

[0198] In embodiments of the present disclosure, the target reference information includes position distribution information of a target display area in the display screen in a target use mode, wherein the target display area can also be an area blocked by the target input device. The target reference information further includes configuration information of the display screen, for example, the number of ELVSS and ELVDD configurations in the driving circuit of the display screen.

[0199] In embodiments of the present disclosure, the target reference information further includes whether the electronic device has an external display device, and display mode information between the electronic device and the external display device.

[0200] In embodiments of the present disclosure, the target reference information further includes whether the electronic device has an external auxiliary device, such as a power supply device, an auxiliary input device, etc.

[0201] In embodiments of the present disclosure, the target reference information further includes running application information of the electronic device. Based on different performance of the electronic device in different running applications, the cathode voltage of the display screen is adjusted to the voltage value corresponding to the running application.

[0202] A second aspect of the present disclosure provides an electronic device, comprising:

[0203] a display screen; and a controller configured to determine a use mode of the electronic device and control a display refresh rate of an available display area of the display screen based on the use mode, wherein in different use modes, a size parameter and / or a display brightness of the available display area of the display screen of the electronic device are different, and the display refresh rate of the available display area is different.

[0204] According to embodiments of the present disclosure, the electronic device includes a first body and a second body rotatably connected, a part of the display screen is exposed on a first face of the first body, and the remaining part of the display screen is accommodated in the first body or the second body; in different use modes of the electronic device, at least part of the display screen is pulled out from the first body or the second body or accommodated in the first body or the second body.

[0205] According to embodiments of the present disclosure, the electronic device includes a first body and a second body rotatably connected, the display screen includes a first area arranged on a second face of the first body and a second area arranged on a third face of the second body.

Based on the change of the rotation angle, the first area of the second surface of the first body 810 and the second area of the third surface of the second body 820 can be individually or in combination to constitute the available display area. Wherein, when the rotation angle exceeds a certain angle value, the opposite surface 830 of the second surface of the second body 820 can individually constitute the available display area.

[0208] Figure 9 Fig. 5 schematically shows the principle diagram of a display control method according to an embodiment of the present disclosure.
