[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] Folding screen display technology is one of the important innovations in the field of display technology in recent years. It combines the function of split-screen display to provide users with a more flexible and diverse user experience.

[0041] In some embodiments, the display panel includes at least two foldable display areas, and a display bending area is provided between adjacent display areas, so that the adjacent display areas can be bent along the display bending area to achieve folding and unfolding of the display panel. In this way, the foldable display panel can freely switch between a compact form and a large-screen experience. Users can enjoy the convenience in the folded state, and after unfolding, they can use a larger display screen for multitasking, watching videos or performing other operations that require a large screen, thereby improving the user's experience. However, in the related art, due to the difference in the use of the partitioned display, the technical problem of brightness life decay difference afterimage will be caused.

[0042] In response to the above technical problems, an embodiment of the present application provides a display panel, which aims to solve the problems of brightness life decay difference, afterimage and screen burn-in caused by partitioned display by designing a brightness compensation area in the display panel, thereby improving the uniformity of the display brightness of the display panel, reducing the brightness difference of the display panel, and further improving the display effect.

[0043] The contents of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application more clearly and in detail.

[0044] in, Figures 2 to 9 In the figure, (a) shows the structure of the display panel, and (b) shows the change of the display brightness of each display area in (a) in the first direction.

[0045] Please refer to Figure 1 As shown, an embodiment of the present application provides a display panel 100, including a foldable display screen, the display screen including a first non-bending area 110, a first bending area 120 and a second non-bending area 130 connected in sequence along a first direction, wherein the first bending area 120 can be bent around an axis extending along a second direction so that the first non-bending area 110 and the second non-bending area 130 can switch between a folded state and a flattened state; wherein the first non-bending area 110 is, for example, an outer screen of the display panel 100, the second non-bending area 130 is an inner screen of the display panel 100, and the second non-bending area 130 can be at least one, for example, in Figure 1 In the figure, there are two second non-bending areas 130, and the two second non-bending areas 130 are connected by a second bending area 140. The second bending area 140 can be bent so that the two adjacent second non-bending areas 130 are in a folded state or a flattened state, thereby forming a three-fold screen.

[0046] It should be noted that when there are multiple second non-bending regions 130 , two adjacent second non-bending regions 130 are connected by a second bending region 140 , so that the two adjacent second non-bending regions 130 can switch between a folded state and an unfolded state.

[0047] Among them, the first non-bending area 110, the first bending area 120 and the second non-bending area 130 all have pixel units arranged in an array. When the first non-bending area 110, the first bending area 120 and the second non-bending area 130 are all in a flattened state, the first non-bending area 110, the first bending area 120 and the second non-bending area 130 are all display areas of the display panel 100 to achieve large-screen display. When a large-screen display is not required, the display panel 100 can be folded to make the display panel 100 in a folded and compact state. At this time, task processing can be achieved by operating the first non-bending area 110.

[0048] Since only the pixel units in the first non-bending area 110 emit light when the display panel 100 is in a folded state and performing task processing, the first non-bending area 110 is used more frequently. Therefore, the difference in the use of this split-screen display will cause a difference in the pixel luminescence brightness life decay of the first non-bending area 110 and the second non-bending area 130, so that there is an obvious visual brightness boundary between the first non-bending area 110 and the second non-bending area 130; for example, in the preliminary design, the maximum brightness of the pixels in the first non-bending area 110 and the maximum brightness of the pixels in the second non-bending area 130 are consistent, but after the display panel 100 has been used for a certain period of time, due to the split-screen use of the first non-bending area 110 and the second non-bending area 130, the pixel luminescence brightness life decay of the first non-bending area 110 decays earlier than the pixel luminescence brightness life decay of the second non-bending area 130, such as Figure 2 As shown in FIG. 1 , the solid line A represents the display brightness of the second non-bending area 130 in the first direction, and the solid line B represents the display brightness of the first non-bending area 110 in the first direction. Figure 2 It can be seen that there is an obvious brightness difference between the display brightness of the first non-bending area 110 and the display brightness of the second non-bending area 130, which leads to an obvious visual boundary between the first non-bending area 110 and the second non-bending area 130, affecting the display effect of the display panel 100 and poor user experience.

[0049] Therefore, based on the above problems, the display panel 100 provided in the embodiment of the present application also includes a brightness compensation area 150. When the display screen is lit, the brightness compensation area 150 is displayed on the first non-bending area 110, the first bending area 120 and / or the second non-bending area 130, so that the first brightness difference between the brightness compensation area 150 and the first non-bending area 110 and the second brightness difference between the brightness compensation area 150 and the second non-bending area 130 are both smaller than a preset threshold value, so as to reduce the display difference between the first non-bending area and the second non-bending area, thereby improving the difference in display brightness of the display panel and enhancing the display effect of the display panel.

[0050] Exemplarily, the brightness compensation zone 150 at least covers the first bending zone 120, or the brightness compensation zone 150 is arranged adjacent to the first bending zone 120, so that the display brightness of the brightness compensation zone 150 is adjustable along the direction from the second non-bending zone 130 to the first non-bending zone 110, that is, the direction from the inner screen to the outer screen. In this way, when there is a display brightness difference between the first non-bending zone 110 and the second non-bending zone 130, the display brightness of the brightness compensation zone 150 can be adjusted so that the brightness difference between the first non-bending zone 110 and the second non-bending zone 130 and the brightness compensation zone 150 is less than a preset threshold value, so that the display brightness transition between the second non-bending zone 130 and the first non-bending zone 110 is performed through the brightness compensation zone 150. For example, when the display brightness of the first non-bending zone 110 is lower than the display brightness of the second non-bending zone 130, the brightness of the brightness compensation zone 150 gradually decreases from a brightness that is approximately consistent with the display brightness of the second non-bending zone 130 (i.e., an obvious boundary that cannot be distinguished by human eyes) to a brightness that is uniformly consistent with the display brightness of the first non-bending zone 110 along the direction from the second non-bending zone 130 to the direction from the second non-bending zone 130 to the first non-bending zone 110. That is, the brightness of the brightness compensation zone 150 gradually decreases from the second non-bending zone 130 to the first non-bending zone 110, thereby improving the obvious visual boundary between the first non-bending zone 110 and the second non-bending zone 130 caused by the brightness difference, thereby improving the display effect of the display panel 100 and the user experience.

[0051] It should be noted that the brightness difference between the first non-bending area 110 and the second non-bending area 130 and the brightness compensation area 150 is less than a preset threshold, which refers to a difference that cannot be clearly distinguished visually, thereby weakening the visual boundary of the display brightness between the first non-bending area 110 and the second non-bending area 130.

[0052] For example, Figure 3 As shown in the figure, the solid line B represents the display brightness after the pixel luminous brightness lifetime decays in the first non-bending zone 110, the solid line A represents the display brightness of the second non-bending zone 130, and the curve C represents the change rule of the display brightness of the brightness compensation zone 150 from the second non-bending zone 130 to the first non-bending zone 110 (that is, the display brightness gradually decreases from the second non-bending zone 130 to the first non-bending zone 110), so that the difference in display brightness between the brightness compensation zone 150 and the first non-bending zone 110 and the second non-bending zone 130 is not recognizable by the naked eye of the user, so that the display brightness of the display panel 100 gradually transitions from bright to dark from the second non-bending zone 130 to the first non-bending zone 110, weakening the visual boundary of the brightness between the first non-bending zone 110 and the second non-bending zone 130, thereby improving the display effect of the display panel 100.

[0053] In some embodiments, the brightness compensation area 150 includes a plurality of columns of pixel units arranged sequentially along a first direction, wherein the display brightness of the pixel units in each column is adjustable, that is, the brightness of the pixel units in the same column is consistent, but the pixel brightness of the pixel units in different columns can be adjusted according to specific needs, so that the display brightness of different columns is different.

[0054] Among them, the pixel unit may include red, blue, green and other pixels, and the details may refer to the relevant technology, which will not be repeated here.

[0055] In addition, a controller is also included, which is electrically connected to each column of pixel units, and the controller is configured to control the display brightness of each column of pixel units; for example, when there is a display brightness difference between the first non-bending area 110 and the second non-bending area 130, the display brightness of each column of pixel units in the brightness compensation area 150 can be adjusted by the controller, so that the display brightness of the brightness compensation area 150 gradually decreases from the second non-bending area 130 to the first non-bending area 110, so as to weaken the obvious visual brightness boundary between the second non-bending area 130 and the first non-bending area 110 through the transition of the display brightness of the brightness compensation area 150.

[0056] In some embodiments, the width of the brightness compensation zone 150 in the first direction can be adaptively designed according to specific needs. As long as the brightness of the brightness compensation zone 150 is adjusted according to specific needs, the obvious visual brightness boundary between the second non-bending zone 130 and the first non-bending zone 110 can be weakened, and no limitation is made here.

[0057] In some embodiments, please refer to Figure 3 As shown, the brightness compensation area 150 at least covers the first bending area 120 and part of the second non-bending area 130, so that the display brightness of the brightness compensation area 150 can be adjusted to weaken the obvious visual brightness boundary between the second non-bending area 130 and the first non-bending area 110, thereby improving the display effect.

[0058] It is understandable that if Figure 3 In the embodiment, along the first direction, the display brightness of the pixel units in the partial area of ​​the second non-bending zone 130 close to the first bending zone 120 and the display brightness of the pixel units in the first bending zone 120 are both adjustable. In this way, the partial area of ​​the second non-bending zone 130 close to the first bending zone 120 and the first bending zone 120 together form a brightness compensation zone 150. From the second non-bending zone 130 to the first non-bending zone 110, the display brightness gradually changes from bright to dark. The gradual change of the display brightness of the brightness compensation zone 150 serves as a transition zone from bright to dark from the second non-bending zone 130 to the first non-bending zone 110, so as to weaken the obvious visual boundary of the first non-bending zone 110 which is obviously darker.

[0059] In other embodiments, along the first direction, the brightness compensation zone 150 at least covers the first bending zone 120 and a portion of the first non-bending zone 110, that is, along the first direction, the display brightness of the pixel units in the first bending zone 120 and a portion of the first non-bending zone 110 close to the first bending zone 120 can be adjusted to jointly form the brightness compensation zone 150, thereby weakening the obvious visual boundary of the first non-bending zone 110 caused by the dark display brightness through the brightness compensation zone 150.

[0060] In some other embodiments, the brightness compensation zone 150 covers at least a portion of the first non-bending zone 110, that is, the brightness compensation zone 150 covers a portion of the first non-bending zone 110 or the entire first non-bending zone 110. In this way, a portion of the first non-bending zone 110 or the entire first non-bending zone 110 together form the brightness compensation zone 150, and each pixel unit in the brightness compensation zone 150 has a compensated gray scale with enhanced brightness. In this way, the brightness gray scale of each pixel unit in the brightness compensation zone 150 can be adjusted so that the display brightness of the brightness compensation zone 150 close to the second non-bending zone 130 is close to the display brightness of the second non-bending zone 130, so as to weaken the obvious visual boundary caused by the dark brightness of the first non-bending zone 110.

[0061] In addition, if Figure 4 and Figure 5 As shown in FIG. 1 , the pixel units in the first non-bending area 110, the second non-bending area 130 and the first bending area 120 can all be set with a compensation gray scale for brightness enhancement. For example, Figure 4 and Figure 5 The dashed lines in the figure all represent the compensation grayscale of the corresponding area. For example, the dashed line D represents the compensation grayscale of the first non-bending area 110 not covered by the brightness compensation area 150, the dashed line E represents the compensation grayscale of the brightness compensation area 150, and the dashed line F represents the compensation grayscale of the second non-bending area 130; Figure 4 and Figure 5As shown in , the brightness compensation area 150 covers the first bending area 120 and part of the second non-bending area 130. In this way, the brightness compensation area 150 is also provided with a compensation grayscale for brightness enhancement, wherein the compensation grayscales of the first non-bending area 110 and the second non-bending area 130 not covered by the brightness compensation area 150 can be the same, and the compensation grayscale for brightness enhancement of the brightness compensation area 150 can gradually decrease from the second non-bending area 130 to the first non-bending area 110. After the display panel 100 is used for a certain period of time, the first non-bending area 110, the second non-bending area 130 and the brightness compensation area 150 are gradually reduced. The display brightness of the brightness compensation area 150 is attenuated, but the brightness attenuation of the first non-bending area 110 is greater than that of the second non-bending area 130, and the brightness attenuation rate of the brightness compensation area 150 is basically consistent with the brightness attenuation rate of the second non-bending area 130. Since the entire display area has a compensation grayscale to enhance the brightness, the brightness of the entire display area can be adjusted to achieve a brightness transition between the second non-bending area 130 and the first non-bending area 110 through the brightness compensation area 150, so that the display area of ​​the entire display panel 100 has no obvious visual boundary.

[0062] in, Figure 5 and Figure 4 The only difference is that Figure 5 The width of the brightness compensation area 150 in the first direction is greater than Figure 4 The width of the middle brightness compensation area 150 in the first direction can be adaptively designed according to specific needs as long as the entire display area of ​​the display panel 100 has no obvious visual boundaries, and is not limited here.

[0063] In other embodiments, Figure 6 As shown in , if the compensation gray scale for boosting brightness of the entire display area of ​​the display panel 100 is consistent, as the display panel 100 is displayed in different zones, the brightness attenuation of the first non-bending area 110 is greater than the brightness attenuation of the second non-bending area 130, thus resulting in the following Figure 6 There is an obvious visual boundary between the first non-bending area 110 and the second non-bending area 130 .

[0064] Therefore, in some embodiments of the present application, please refer to Figure 7 As shown, the brightness compensation area 150 covers a portion of the first non-bending area 110, and the maximum compensation grayscale of the brightness increase of the brightness compensation area 150 is greater than the compensation grayscale of the brightness increase of other display areas, so that after a certain period of use, the brightness of the entire display area decays, and the brightness transition between the first non-bending area 110 and the second non-bending area 130 is achieved by adjusting the brightness of the entire display area and adjusting the display brightness of the brightness compensation area 150, so as to weaken the obvious visual boundary between the first non-bending area 110 and the second non-bending area 130.

[0065] Please refer to Figure 8 As shown, Figure 8 The structure and Figure 7 The structure in is only that Figure 8 The width of the brightness compensation area 150 in the first direction is greater than Figure 7 The width of the brightness compensation area 150 in the first direction, and Figure 8 The maximum compensation gray scale of the brightness improvement in the brightness compensation area 150 is greater than the compensation gray scales of the brightness improvement in other display areas.

[0066] In some other embodiments, please refer to Fig. 9 As shown, the brightness compensation area 150 covers the first non-bending area 110, and the compensation grayscale of the brightness increased in the brightness compensation area 150 gradually decreases from the second non-bending area 130 to the first non-bending area 110, and the maximum compensation grayscale of the brightness increased in the brightness compensation area 150 is greater than the compensation grayscale of the brightness increased in the second non-bending area 130, and the minimum compensation grayscale of the brightness increased in the brightness compensation area 150 is equal to the compensation grayscale of the brightness increased in the second non-bending area 130. In this way, when the brightness of the entire display area is attenuated, the display brightness in the second non-bending area 130 and the brightness compensation area 150 can be adjusted to weaken the obvious visual boundary between the first non-bending area 110 and the second non-bending area 130, thereby improving the brightness uniformity of the display area and improving the display effect of the entire display area.

[0067] It should be noted that when brightness adjustment is required, the user can adjust and calibrate it by himself through a foldable electronic device to which the display panel 100 is applicable, so that the user can make adjustments according to his subjective vision, thereby improving the user experience.

[0068] An embodiment of the present application further provides an electronic device, which includes the display panel 100 provided in the above embodiment, wherein the structure of the display panel 100 has been described in detail in the above embodiment and will not be repeated here.

[0069] In addition, electronic devices include but are not limited to foldable mobile phones, tablets, PDAs, etc., wherein the display panel 100 of the electronic device can be a partitioned display that is folded in two, three or more folds, and if there is a display brightness difference afterimage between any two adjacent display areas, the problem of display brightness difference between adjacent display areas can be solved by the technical solution of the above embodiment.

[0070] In summary, the display panel and electronic device provided in the embodiments of the present application include a first non-bending zone, a first bending zone, and a second bending zone connected in sequence along a first direction. The first bending zone can be bent around an axis extending along the second direction so that the first non-bending zone and the second bending zone can switch between a folded state and a flattened state, and a brightness compensation zone is set in the display panel, so that the brightness compensation zone at least covers the first bending zone or is set adjacent to the first bending zone. Along the direction from the second bending zone to the first non-bending zone, the display brightness of the brightness compensation zone is adjustable so that the brightness difference between the first non-bending zone and the second bending zone is less than a preset threshold value (for example, a threshold value that cannot be recognized by the human eye), thereby improving the difference in display brightness of the display panel and enhancing the display effect of the display panel.

[0071] The electronic device may be implemented in various forms. For example, the electronic devices described in this application may include electronic devices such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and fixed electronic devices such as digital TVs and desktop computers.

Specifically, after receiving the downlink information of the base station, it is sent to the processor 310 for processing; in addition, the uplink data is sent to the base station. Generally, the radio frequency unit 301 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 301 can also communicate with the network and other devices through wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution) and 5G, etc.

[0076] WiFi is a short-range wireless transmission technology. The mobile terminal can help users send and receive emails, browse web pages and access streaming media through the WiFi module 302. It provides users with wireless broadband Internet access. Figure 1 A WiFi module 302 is shown, but it is understandable that it is not an essential component of the mobile terminal and can be omitted as required without changing the essence of the invention.

[0077] The audio output unit 303 can convert the audio data received by the RF unit 301 or the WiFi module 302 or stored in the memory 309 into an audio signal and output it as sound when the mobile terminal 300 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 303 can also provide audio output related to a specific function performed by the mobile terminal 300 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 303 may include a speaker, a buzzer, etc.

[0078] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 304 may include a graphics processor (GPU) 3041 and a microphone 3042, and the graphics processor 3041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 306. The image frame processed by the graphics processor 3041 can be stored in the memory 309 (or other storage medium) or sent via the radio frequency unit 301 or the WiFi module 302. The microphone 3042 can receive sound (audio data) via the microphone 3042 in a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 301 in the case of a telephone call mode. The microphone 3042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

[0079] The mobile terminal 300 also includes at least one sensor 305, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 3061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 3061 and / or the backlight when the mobile terminal 300 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can also be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

Optionally, the user input unit 307 may include a touch panel 3071 and other input devices 3072. The touch panel 3071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 3071 or near the touch panel 3071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 3071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 310, and can receive and execute the command sent by the processor 310. In addition, the touch panel 3071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 3071, the user input unit 307 may also include other input devices 3072. Optionally, the other input devices 3072 may include, but are not limited to, one or more of a physical keyboard, a function key (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, etc., which are not specifically limited here.

[0082] Optionally, the touch panel 3071 may cover the display panel 3061. When the touch panel 3071 detects a touch operation on or near it, it transmits the information to the processor 310 to determine the type of touch event. Then, the processor 310 provides corresponding visual output on the display panel 3061 according to the type of touch event. Figure 1 In the figure, the touch panel 3071 and the display panel 3061 are used as two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 3071 and the display panel 3061 can be integrated to realize the input and output functions of the mobile terminal, which is not limited here.

[0083] The interface unit 308 serves as an interface through which at least one external device can be connected to the mobile terminal 300.

[0084] The memory 309 can be used to store software programs and various data. The memory 309 can mainly include a program storage area and a data storage area. Optionally, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 309 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0085] The processor 310 is the control center of the mobile terminal. It uses various interfaces and lines to connect various parts of the entire mobile terminal. It executes various functions of the mobile terminal and processes data by running or executing software programs and / or modules stored in the memory 309, and calling data stored in the memory 309, so as to monitor the mobile terminal as a whole. The processor 310 may include one or more processing units; preferably, the processor 310 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 310.

[0086] The mobile terminal 300 may also include a power supply 311 (such as a battery) for supplying power to various components. Preferably, the power supply 311 may be logically connected to the processor 310 via a power management system, thereby implementing functions such as managing charging, discharging, and power consumption management through the power management system.
