Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to display devices and driving methods thereof. Background Technology

[0002] With the rapid development of display technology, touch screen panels have gradually become ubiquitous in people's lives. Currently, touch screens can be categorized by their structure into: add-on touch panels, on-cell touch panels, and in-cell touch panels. Add-on touch panels are manufactured separately from the liquid crystal display (LCD) screen and then bonded together to form a touch-enabled LCD screen. Add-on touch panels suffer from drawbacks such as higher manufacturing costs, lower light transmittance, and thicker modules. In contrast, in-cell touch panels embed the touch electrodes within the LCD screen, reducing the overall thickness of the module and significantly lowering manufacturing costs, making them favored by major panel manufacturers.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Furthermore, the embodiments and features in the embodiments of this disclosure can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0071] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0072] It should be noted that the dimensions and shapes of the figures in the accompanying drawings do not reflect actual proportions and are intended only to illustrate the content of this disclosure. Furthermore, the same or similar reference numerals are used throughout to denote the same or similar elements or elements having the same or similar functions. This disclosure provides some display devices, such as… Figure 1 As shown, it includes:

[0073] Display panel 100;

[0074] The drive control circuit 200, coupled to the display panel 100, is configured as follows:

[0075] When it is determined that there is an operating body in front of the display panel 100, the distance between a set part of the operating body and the display panel is obtained;

[0076] Determine whether the distance meets the preset distance threshold;

[0077] If so, then the display panel 100 is driven in display touch mode, so that the display panel 100 has a display stage and a touch stage in the next display frame;

[0078] If not, then the display mode is selected to drive the display panel 100, so that the display panel 100 has a display stage in the next display frame.

[0079] In this embodiment, when the driving control circuit determines that there is a manipulator in front of the display panel, it can obtain the distance between a set part of the manipulator and the display panel. By determining whether this distance meets a preset distance threshold, it can determine whether the manipulator will touch the display panel. If it is determined that the distance does not meet the preset distance threshold, it can be determined that the manipulator will not touch the display panel. In this case, the driving control circuit drives the display panel in a display mode, so that the display panel only has a display phase and no touch phase in a display frame. This increases the duration of the display phase in a display frame, thereby increasing the charging time required for the display phase, which can reduce the charging voltage, thereby reducing power consumption and display cost.

[0080] When the distance meets the preset distance threshold, it can be determined that the operator will touch the display panel. Then the drive control circuit drives the display panel in the display touch mode, so that the display panel has both a display stage and a touch stage in a display frame, thereby ensuring that the display panel can perform touch operation on the basis of being able to display the screen.

[0081] For example, the area in front of the display panel can be the surrounding environment on the side where the display screen is shown.

[0082] For example, the manipulator may include, but is not limited to, objects capable of controlling the display device, such as the human body or a stylus. For instance, when the manipulator is the human body, the designated area may be a part of the human body capable of touch operation, such as the hand or foot. When the manipulator is a stylus, the designated area may be a part of the stylus capable of touch operation, such as the pen tip.

[0083] In this embodiment, the display panel includes a display area and a non-display area. The display area may include multiple pixel units, multiple gate lines, and multiple data lines. Each pixel unit includes multiple sub-pixels. For example, the multiple sub-pixels may include red, green, and blue sub-pixels, allowing for color mixing to achieve color display. Alternatively, the multiple sub-pixels may include red, green, blue, and white sub-pixels, also allowing for color mixing to achieve color display. Of course, in practical applications, the emission color of the sub-pixels in a pixel unit can be designed and determined according to the actual application environment, and is not limited here.

[0084] In some examples, a row of subpixels can be connected to one or more gate lines, and a column of subpixels can be connected to one or more data lines.

[0085] In some examples, the non-display area includes one or more source driver circuits and gate driver circuits. The display area includes one or more display sub-regions. Furthermore, each display sub-region is associated with a source driver circuit, and the source driver circuit is connected to the data lines in the corresponding display sub-region. The specific number of source driver circuits can be determined according to the needs of the actual application and is not limited here.

[0086] For example, such as Figure 2 As shown, the display panel 100 includes: a gate driving circuit 110, and multiple gate lines (e.g., Figure 2The gate driving circuit 110 is coupled to the gate lines GA1, GA2, and GA3 respectively. The display panel 100 includes: a first source driving circuit SIC1, a second source driving circuit SIC2, a third source driving circuit SIC3, a fourth source driving circuit SIC4, a fifth source driving circuit SIC5, and a sixth source driving circuit SIC6; a first display sub-region XD1, a second display sub-region XD2, a third display sub-region XD3, a fourth display sub-region XD4, a fifth display sub-region XD5, and a sixth display sub-region XD6. Of course, the display panel may also include: 2 display sub-regions and 2 source driving circuits, 3 display sub-regions and 3 source driving circuits, 4 display sub-regions and 4 source driving circuits, 8 display sub-regions and 8 source driving circuits, 10 display sub-regions and 10 source driving circuits, etc., and is not limited here.

[0087] For example, such as Figure 2 As shown, each display sub-area in the display panel 100 (e.g.) Figure 2 The first display sub-region XD1, the second display sub-region XD2, the third display sub-region XD3, the fourth display sub-region XD4, the fifth display sub-region XD5, and the sixth display sub-region XD6 include: multiple sub-pixels SPX, data lines (e.g., ... Figure 2 (DA1, DA2, DA3, DA4, DA5, DA6). The first source driver circuit SIC1, the second source driver circuit SIC2, the third source driver circuit SIC3, the fourth source driver circuit SIC4, the fifth source driver circuit SIC5, and the sixth source driver circuit SIC6 are coupled to the data lines DA1, DA2, DA3, DA4, DA5, and DA6, respectively. Each sub-pixel SPX includes a pixel electrode 1 and a switching transistor 2. One row of sub-pixels SPX corresponds to one gate line, and one column of sub-pixels SPX corresponds to one data line. The gate of the switching transistor 2 is electrically connected to the corresponding gate line, the source of the switching transistor 2 is electrically connected to the corresponding data line, and the drain of the switching transistor 2 is electrically connected to the pixel electrode 1.

[0088] It should be noted that the pixel array structure disclosed herein can also be a dual-gate structure, that is, two gate lines are set between two adjacent rows of pixels. This arrangement can reduce the number of data lines by half, that is, it includes data lines between two adjacent columns of pixels, and does not include data lines between two adjacent columns of pixels. The specific pixel arrangement structure, data lines, and scan line arrangement are not limited.

[0089] In this embodiment of the disclosure, each display sub-region may further include multiple data lines; a source driving circuit is coupled to all data lines within a display sub-region. For example, as shown... Figure 3 As shown, each display sub-area in the display panel 100 (e.g.) Figure 3The first display sub-region XD1, second display sub-region XD2, third display sub-region XD3, fourth display sub-region XD4, fifth display sub-region XD5, and sixth display sub-region XD6 may also include multiple data lines DA; for example, the first display sub-region XD1 includes 5 data lines DA, and the first source driver circuit SIC1 is coupled to the 5 data lines DA in the first display sub-region XD1. The second display sub-region XD2 includes 5 data lines DA, and the second source driver circuit SIC2 is coupled to the 5 data lines DA in the second display sub-region XD2. The third display sub-region XD3 includes 5 data lines DA, and the third source driver circuit SIC3 is coupled to the 5 data lines DA in the third display sub-region XD3. The fourth display sub-region XD4 includes 5 data lines DA, and the fourth source driver circuit SIC4 is coupled to the 5 data lines DA in the fourth display sub-region XD4. The fifth display sub-region XD5 includes 5 data lines DA, and the fifth source driver circuit SiC5 is coupled to the 5 data lines DA within the fifth display sub-region XD5. The sixth display sub-region XD6 includes 5 data lines DA, and the sixth source driver circuit SiC6 is coupled to the 5 data lines DA within the sixth display sub-region XD6. Of course, each display sub-region can also include 1 data line, 2 data lines, 3 data lines, 4 data lines, 6 data lines, etc., which is not limited here.

[0090] In the embodiments disclosed herein, such as Figure 2 As shown, the drive control circuit 200 is further configured to: when determining that the display panel 100 is driven in a display touch mode, control at least one source drive circuit (e.g., ...) in the next display frame. Figure 2 The first source driver circuit SIC1, the second source driver circuit SIC2, the third source driver circuit SIC3, the fourth source driver circuit SIC4, the fifth source driver circuit SIC5, and the sixth source driver circuit SIC6 in the display phase provide the first data voltage to the coupled data line DA; when it is determined that the display mode is used to drive the display panel 100, in the next display frame, each source driver circuit (e.g., Figure 2 The first source driving circuit SIC1, the second source driving circuit SIC2, the third source driving circuit SIC3, the fourth source driving circuit SIC4, the fifth source driving circuit SIC5, and the sixth source driving circuit SIC6 in the display stage provide the second data voltage to the coupled data line DA; the first data voltage is greater than the second data voltage, corresponding to the first data voltage and the second data voltage of the same gray level.

[0091] It should be noted that the source drive circuit only needs to provide the first data voltage to the coupled data line during the display stage. During the touch stage, the source drive circuit does not work to reduce power consumption.

[0092] Grayscale, in general, divides the brightness variation between the darkest and brightest points into several parts to facilitate screen brightness control. For example, a displayed image may consist of three colors: red, green, and blue. Each color can be displayed at different brightness levels, and combinations of different brightness levels of red, green, and blue can form different colors. For instance, if an LCD panel has a grayscale bit depth of 6 bits, then red, green, and blue each have 64 (i.e., 2^34) grayscale values. 6 There are 64 gray levels, with gray values ​​ranging from 0 to 63. If the LCD panel has an 8-bit grayscale bit depth, then red, green, and blue each have 256 (i.e., 2^6) gray levels. 8 There are 256 gray levels, with gray values ​​ranging from 0 to 255. If the LCD panel has a 10-bit grayscale, then red, green, and blue each have 1024 (i.e., 2^35) grayscale values. 10 There are 1024 gray levels, with gray values ​​ranging from 0 to 1023. If the LCD panel has a 12-bit grayscale, then red, green, and blue each have 4096 (i.e., 2^3) gray levels. 12 There are 4096 gray levels, with gray values ​​ranging from 0 to 4093.

[0093] Taking a grayscale value of 0 to 255 as an example, for the first data voltage and the second data voltage with a corresponding grayscale value of 100, the first data voltage is greater than the second data voltage.

[0094] In practical applications, the specific voltage values ​​of the first and second data voltages need to be determined based on the grayscale of the desired brightness. That is, the specific voltage value of the first data voltage differs for different grayscale levels, and the specific voltage value of the second data voltage also differs for different grayscale levels. Furthermore, the specific values ​​of the first and second data voltages can be designed and determined according to the actual application environment, and are not limited here.

[0095] For example, such as Figure 2 and Figure 3As shown, each source driver circuit (e.g., the first source driver circuit SIC1, the second source driver circuit SIC2, the third source driver circuit SIC3, the fourth source driver circuit SIC4, the fifth source driver circuit SIC5, and the sixth source driver circuit SIC6 in the figure) is respectively mounted on a chip-on-film (COF) film. COF film is a die-on-film packaging technology that fixes the source driver circuits (e.g., the first source driver circuit SIC1, the second source driver circuit SIC2, the third source driver circuit SIC3, the fourth source driver circuit SIC4, the fifth source driver circuit SIC5, and the sixth source driver circuit SIC6 in the figure) onto a flexible printed circuit board (FPC). It uses a flexible attached circuit board as a chip carrier to combine the chip with the flexible substrate circuit, or specifically refers to a flexible attached circuit board without a packaged chip. This includes tape-and-reel packaging production, flexible board-to-chip assembly, and integrated circuit chip (IC) carrier board packaging.

[0096] For example, such as Figure 2 and Figure 3 As shown, the first source drive circuit SIC1 is disposed on the first flip-chip film COF1, the second source drive circuit SIC2 is disposed on the second flip-chip film COF2, the third source drive circuit SIC3 is disposed on the third flip-chip film COF3, the fourth source drive circuit SIC4 is disposed on the fourth flip-chip film COF4, the fifth source drive circuit SIC5 is disposed on the fifth flip-chip film COF5, and the sixth source drive circuit SIC6 is disposed on the sixth flip-chip film COF6.

[0097] In this embodiment of the disclosure, the drive control circuit is further configured to: when it is determined that the display panel is driven in a display touch mode, in the next display frame, control each source drive circuit to provide a first data voltage to the coupled data line during the display phase.

[0098] In the embodiments disclosed herein, such as Figure 4 As shown, the drive control circuit 200 includes: a posture detection processor 210, a timing controller 220, and a touch drive circuit 230.

[0099] For example, such as Figure 5 As shown, a sensor is also provided on the bezel of the display device. For example, the sensor can be an infrared sensor, an ultrasonic sensor, etc. In practical applications, the specific type of sensor can be designed and determined according to the actual application environment, and is not limited here.

[0100] Taking an infrared sensor as an example, in practical applications, the infrared sensor continuously emits infrared signals and receives reflected infrared signals. Based on the time difference between emitting and receiving the reflected infrared signals, the infrared sensor collects information about the surrounding environment on one side of the display panel and transmits the acquired information to the attitude detection processor.

[0101] In the embodiments disclosed herein, such as Figure 4 As shown, the posture detection processor 210 is configured to, when it is determined that there is a manipulator in front of the display panel 100, obtain the distance between a set part of the manipulator and the display panel, and output a display touch control signal when it is determined that the distance meets a preset distance threshold.

[0102] For example, the distance threshold is preset, for instance, stored in the drive control circuit. Optionally, the distance threshold can be the orthographically projected distance. Of course, the distance threshold can also be other forms of distance, which are not limited here.

[0103] For example, the distance threshold can be 1mm, 2mm, 3mm, 4mm, 5mm, etc. The specific value of the distance threshold can be designed and determined according to the actual application environment, and is not limited here.

[0104] For example, the posture detection processor determines whether the surrounding environment contains a manipulator based on the surrounding environment information collected by the infrared sensor on one side of the display panel. When the posture detection processor determines that the surrounding environment contains a manipulator, it then determines the distance between the hand in the manipulator and the display panel. When the distance meets a preset distance threshold (e.g., 5mm), it outputs a display touch control signal.

[0105] In the embodiments disclosed herein, such as Figure 4 As shown, the timing controller 220 is configured to receive a display touch control signal, determine the use of a display touch mode, and in the next display frame, control each source driver circuit (e.g., the first source driver circuit SIC1, the second source driver circuit SIC2, the third source driver circuit SIC3, the fourth source driver circuit SIC4, the fifth source driver circuit SIC5, and the sixth source driver circuit SIC6 in the figure) to provide a first data voltage to the coupled data line during the display phase. The touch driver circuit 230 is configured to receive the display touch control signal and perform a touch operation during the touch phase in the next display frame.

[0106] When the display touch mode is used, the display panel has both a display stage and a touch stage, thus ensuring that the display panel can perform touch operations on the basis of displaying the image.

[0107] In the embodiments disclosed herein, such as Figure 4 As shown, the posture detection processor 210 is configured to, when it is determined that there is a manipulator in front of the display panel 100, acquire the distance between a set part of the manipulator and the display panel, and output a display control signal when it is determined that the distance does not meet a preset distance threshold.

[0108] For example, the posture detection processor determines whether the surrounding environment contains a manipulator based on the surrounding environment information collected by the infrared sensor on one side of the display panel. When the posture detection processor determines that the surrounding environment contains a manipulator, it then determines the distance between the hand in the manipulator and the display panel. If the distance is greater than 5mm, it outputs a display control signal.

[0109] In the embodiments disclosed herein, such as Figure 4 As shown, the timing controller 220 is configured to receive a display control signal, determine the display mode to be used, and in the next display frame, control each source driver circuit (e.g., the first source driver circuit SIC1, the second source driver circuit SIC2, the third source driver circuit SIC3, the fourth source driver circuit SIC4, the fifth source driver circuit SIC5, and the sixth source driver circuit SIC6 in the figure) to provide the second data voltage to the coupled data line during the display phase. The touch driver circuit 230 is configured to receive the display control signal and not perform touch operation in the next display frame.

[0110] When in display mode, the display panel only has a display phase and no touch phase. Therefore, the display phase takes up the time required for the touch phase, thus increasing the display phase time. The time it takes for the source driver circuit to supply the second data voltage to the coupled data line during the display phase also increases. In other words, the charging time is longer. Therefore, the data voltage required in display mode is smaller than that required in touch mode, resulting in lower power consumption and lower display costs.

[0111] This disclosure provides a driving method for a display device, such as... Figure 6 As shown, it includes:

[0112] S100: When it is determined that there is an operating body in front of the display panel, the distance between a set part of the operating body and the display panel is obtained;

[0113] S200, Determine whether the distance meets the preset distance threshold;

[0114] S300, If yes, then determine to drive the display panel using the display touch mode, so that the display panel has a display stage and a touch stage in the next display frame;

[0115] S400, If not, then determine to use the display mode to drive the display panel, so that the display panel has a display stage in the next display frame.

[0116] In some examples, determining to drive the display panel in a display touch mode, such that the display panel has a display phase and a touch phase in the next display frame, includes: when determining to drive the display panel in a display touch mode, in the next display frame, controlling at least one source driving circuit to provide a first data voltage to a coupled data line in the display phase.

[0118] Furthermore, for the first data voltage and the second data voltage corresponding to the same gray level, the first data voltage is greater than the second data voltage.

[0119] In some examples, the driving method includes: when it is determined that the display panel is driven in a display touch mode, in the next display frame, controlling each source driving circuit to provide a first data voltage to the coupled data line during the display phase.

[0120] In some examples, the driving method includes: when the distance meets a distance threshold, determining a target display sub-region from multiple display sub-regions based on the region where the set part is located; when it is determined that the display panel is driven in a display touch mode, in the next display frame, controlling the source driving circuit corresponding to the target display sub-region to provide a first data voltage to the coupled data line during the display phase.

[0121] The following is based on Figure 4 Taking the display device shown as an example, combined with Figures 7 to 9 The signal timing diagram shown describes the operation of the display device provided in the embodiments of this disclosure. Furthermore, the human body is used as an example to illustrate the manipulation.

[0122] In the embodiments disclosed herein, such as Figure 7 As shown, TX represents the display control signal, Vcom represents the common electrode voltage signal, da represents the data voltage signal, and ga represents the gate scan signal. Figure 7 This diagram illustrates the signal timing of the display device during the display phase DP operation in a display frame 1H.

[0123] like Figure 8 As shown, TE represents the display touch control signal, Vcom represents the common electrode voltage signal, da represents the data voltage signal, and ga represents the gate scan signal. Among these, Figure 8This diagram illustrates the signal timing of the display device's operation during the display phase DP and touch phase TC within a display frame 1H. Figure 9 The signal timing diagram illustrates the operation process of the display device in display frame nH during the display phase DP, and in display frame (n+1)H during the display phase DP and touch phase TC.

[0124] When a human body is detected in front of the display panel, the distance between a designated part of the human body and the display panel is obtained. If the distance does not meet a preset distance threshold, the display panel is driven in a display mode, enabling it to have a display phase in the next display frame. During the display phase DP, the first source driver circuit SIC1 provides the second data voltage of the data voltage signal da to the coupled data line DA1; the second source driver circuit SIC2 provides the second data voltage of the data voltage signal da to the coupled data line DA2; the third source driver circuit SIC3 provides the second data voltage of the data voltage signal da to the coupled data line DA3; the fourth source driver circuit SIC4 provides the second data voltage of the data voltage signal da to the coupled data line DA4; the fifth source driver circuit SIC5 provides the second data voltage of the data voltage signal da to the coupled data line DA5; and the sixth source driver circuit SIC6 provides the second data voltage of the data voltage signal da to the coupled data line DA6. The gate driver circuit 110 provides gate scan signals line by line, controlling the switching transistor 2 to turn on line by line. The conducting switching transistor 2 provides the second data voltage on the data line to the pixel electrode 1, thereby charging the pixel electrode 1 and realizing the screen display function.

[0125] When a human body is detected in front of the display panel, the distance between a designated part of the human body and the display panel is obtained. If the distance meets a preset distance threshold, the display panel is driven in a display touch mode, enabling the display panel to have both a display phase and a touch phase in the next display frame. In the display phase DP, the first source driving circuit SIC1 provides the first data voltage of the data voltage signal da to the coupled data line DA1, the second source driving circuit SIC2 provides the first data voltage of the data voltage signal da to the coupled data line DA2, the third source driving circuit SIC3 provides the first data voltage of the data voltage signal da to the coupled data line DA3, the fourth source driving circuit SIC4 provides the first data voltage of the data voltage signal da to the coupled data line DA4, the fifth source driving circuit SIC5 provides the first data voltage of the data voltage signal da to the coupled data line DA5, and the sixth source driving circuit SIC6 provides the first data voltage of the data voltage signal da to the coupled data line DA6. The gate driving circuit 110 provides gate scan signals row by row, controlling the switching transistor 2 to turn on row by row. The conducting switching transistor 2 provides the first data voltage on the data line to the pixel electrode 1, thereby charging the pixel electrode 1 and realizing the screen display function.

[0126] In the touch phase TC, the touch driving circuit 230 receives the display touch control signal and loads the touch driving signal onto the display panel to perform touch scanning, thereby ensuring that people can perform touch operations.

[0127] In a certain display frame nH, the drive control circuit 200 drives the display panel 100 in display mode according to the received display control signal. In display mode, the display panel 100 only has the display stage DP. At a certain point in this display frame, the drive control circuit 200 receives a display touch control signal, but in this display frame, the drive control circuit 200 still drives the display panel 100 in display mode. In the next display frame n+1H, the drive control circuit 200 drives the display panel 100 in display touch mode according to the received display touch control signal.

[0128] In other embodiments of this disclosure, the drive control circuit is further configured to: when the distance meets a distance threshold, determine a target display sub-region from multiple display sub-regions based on the region where the set part is located; when it is determined that the display panel is driven in a display touch mode, in the next display frame, control the source drive circuit corresponding to the target display sub-region to provide a first data voltage to the coupled data line during the display phase.

[0129] For example, such as Figure 10As shown, the following explanation will take the fourth display sub-region XD4 as an example. The drive control circuit 200 is also configured to: when the distance meets the distance threshold, determine the target display sub-region as the fourth display sub-region XD4 from the first display sub-region XD1, the second display sub-region XD2, the third display sub-region XD3, the fourth display sub-region XD4, the fifth display sub-region XD5, and the sixth display sub-region XD6 according to the set position; when it is determined that the display panel is driven in display touch mode, in the next display frame, control the fourth source drive circuit SIC4 corresponding to the fourth display sub-region XD4 to provide the first data voltage to the coupled data line DA during the display stage.

[0130] In this embodiment of the disclosure, the drive control circuit is further configured to control the source drive circuits corresponding to the remaining display sub-regions other than the target display sub-region to provide the second data voltage to the coupled data line during the display phase.

[0131] For example, such as Figure 10 As shown, the drive control circuit 200 is further configured to: control the first source drive circuit SIC1 corresponding to the first display sub-region XD1 to provide a second data voltage to the coupled data line DA during the display phase; control the second source drive circuit SIC2 corresponding to the second display sub-region XD2 to provide a second data voltage to the coupled data line DA during the display phase; control the third source drive circuit SIC3 corresponding to the third display sub-region XD3 to provide a second data voltage to the coupled data line DA during the display phase; control the fifth source drive circuit SIC5 corresponding to the fifth display sub-region XD5 to provide a second data voltage to the coupled data line DA during the display phase; and control the sixth source drive circuit SIC6 corresponding to the sixth display sub-region XD6 to provide a second data voltage to the coupled data line DA during the display phase.

[0132] In the embodiments disclosed herein, such as Figure 10 and Figure 18 As shown, each sub-pixel SPX in the display panel 100 includes: a gating control circuit 120 and a pixel electrode 1 coupled to the gating control circuit 120; the gating control circuit 120 in a row of sub-pixels SPX is coupled to a data line DA.

[0133] The gating control circuit 120 is configured to provide a first data voltage transmitted on the coupled data line DA to the pixel electrode 1 in response to an effective level signal of the first control terminal EN1 and a first scan signal of the first scan terminal CS1; and to provide a second data voltage transmitted on the coupled data line DA to the pixel electrode 1 in response to an effective level signal of the second control terminal EN2 and a second scan signal of the second scan terminal CS2.

[0134] The drive control circuit 200 is further configured to: load a valid level signal onto the first control terminal EN1 of the gating control circuit 120 in the target display sub-region (taking the fourth display sub-region XD4 as an example), load an invalid level signal onto the second control terminal EN2 of the gating control circuit 120 in the target display sub-region (taking the fourth display sub-region XD4 as an example), load a valid level signal onto the second control terminal EN2 of the gating control circuit 120 in the remaining display sub-regions (taking the first display sub-region XD1, the second display sub-region XD2, the third display sub-region XD3, the fifth display sub-region XD5, and the sixth display sub-region XD6 as examples), and load an invalid level signal onto the first control terminal EN1 of the gating control circuit 120 in the remaining display sub-regions (taking the first display sub-region XD1, the second display sub-region XD2, the third display sub-region XD3, the fifth display sub-region XD5, and the sixth display sub-region XD6 as examples).

[0135] In the embodiments disclosed herein, such as Figure 10 and Figure 18 As shown, the gating control circuit 120 includes: a first transistor T1, a second transistor T2, a third transistor T3, and a fourth transistor T4;

[0136] The gate of the first transistor T1 is coupled to the first control terminal EN1, the first electrode of the first transistor T1 is coupled to the first scan terminal CS1, and the second electrode of the first transistor T1 is coupled to the gate of the second transistor T2.

[0137] The first terminal of the second transistor T2 is coupled to the data line DA, and the second terminal of the second transistor T2 is coupled to the pixel electrode 1.

[0138] The gate of the third transistor T3 is coupled to the second control terminal EN2, the first terminal of the third transistor T3 is coupled to the second scan terminal CS2, and the second terminal of the third transistor T3 is coupled to the gate of the fourth transistor T4.

[0139] The first terminal of the fourth transistor T4 is coupled to the data line DA, and the second terminal of the fourth transistor T4 is coupled to the pixel electrode 1.

[0140] For example, the first transistor T1 can be turned on under the control of a valid level signal transmitted at the first control terminal EN1, and can be turned off under the control of an invalid level signal transmitted at the first control terminal EN1. For example, the first transistor T1 is configured as an N-type transistor, with a high level for the valid level signal and a low level for the invalid level signal. Alternatively, the first transistor T1 can be configured as a P-type transistor, with a low level for the valid level signal and a high level for the invalid level signal. For example, a signal formed by a voltage greater than or equal to 8V can be considered a high-level signal, and a signal formed by a voltage less than or equal to 0V can be considered a low-level signal. Furthermore, the 8V and 0V mentioned above are merely illustrative examples; in practical applications, the voltages forming a high-level signal and a low-level signal can be determined according to the needs of the actual application and are not limited here.

[0141] For example, the second transistor T2 can be turned on under the control of the effective level signal of the first scan signal transmitted at the first scan terminal CS1, and can be turned off under the control of the ineffective level signal of the first scan signal transmitted at the first scan terminal CS1. For example, the second transistor T2 is configured as an N-type transistor, with the effective level signal being high and the ineffective level signal being low. Alternatively, the second transistor T2 can be configured as a P-type transistor, with the effective level signal being low and the ineffective level signal being high. For example, a signal formed by a voltage greater than or equal to 8V can be considered a high-level signal, and a signal formed by a voltage less than or equal to 0V can be considered a low-level signal. Furthermore, the 8V and 0V mentioned above are merely illustrative examples; in practical applications, the voltages forming a high-level signal and a low-level signal can be determined according to the needs of the actual application and are not limited here.

[0142] For example, the third transistor T3 can be turned on under the control of a valid level signal transmitted at the second control terminal EN2, and can be turned off under the control of an invalid level signal transmitted at the second control terminal EN2. For example, the third transistor T3 is configured as an N-type transistor, with a high level for the valid level signal and a low level for the invalid level signal. Alternatively, the third transistor T3 can be configured as a P-type transistor, with a low level for the valid level signal and a high level for the invalid level signal. For example, a signal formed by a voltage greater than or equal to 8V can be considered a high-level signal, and a signal formed by a voltage less than or equal to 0V can be considered a low-level signal. Furthermore, the 8V and 0V mentioned above are merely illustrative examples; in practical applications, the voltages forming a high-level signal and a low-level signal can be determined according to the needs of the actual application and are not limited here.

[0143] For example, the fourth transistor T4 can be turned on under the control of the effective level signal of the second scan signal transmitted at the second scan terminal CS2, and can be turned off under the control of the ineffective level signal of the second scan signal transmitted at the second scan terminal CS2. For example, the fourth transistor T4 is configured as an N-type transistor, with the effective level signal being high and the ineffective level signal being low. Alternatively, the fourth transistor T4 can be configured as a P-type transistor, with the effective level signal being low and the ineffective level signal being high. For example, a signal formed by a voltage greater than or equal to 8V can be considered a high-level signal, and a signal formed by a voltage less than or equal to 0V can be considered a low-level signal. Furthermore, the 8V and 0V mentioned above are merely illustrative examples; in practical applications, the voltages forming a high-level signal and a low-level signal can be determined according to the needs of the actual application and are not limited here.

[0144] In this embodiment of the disclosure, the drive control circuit includes: a posture detection processor, a timing controller, a touch drive circuit, and a level conversion circuit;

[0145] The posture detection processor is configured to, when it is determined that there is a manipulator in front of the display panel, obtain the distance between a set part of the manipulator and the display panel, output a display touch control signal when it is determined that the distance meets a preset distance threshold, and, based on the set part, determine a target display sub-region from multiple display sub-regions and output information about the target display sub-region.

[0146] For example, the distance threshold can be 1mm, 2mm, 3mm, 4mm, 5mm, etc. The specific value of the distance threshold can be designed and determined according to the actual application environment, and is not limited here.

[0147] For example, the set part can be a part of the control body that can be touched, such as the hand or foot.

[0148] The timing controller is configured to receive the display touch control signal and the information of the target display sub-area, determine the display touch mode to be adopted, and in the next display frame, control the source drive circuit corresponding to the target display sub-area to provide the first data voltage to the coupled data line during the display phase.

[0149] The touch driving circuit is configured to receive display touch control signals and perform touch operations during the touch phase in the next display frame.

[0150] The level conversion circuit is configured to receive the display touch control signal, make the output of the first control terminal an effective level signal, and make the output of the second control terminal an invalid level signal.

[0151] For example, such as Figure 10As shown, the following explanation will take the target display sub-area as the fourth display sub-area XD4 as an example. The drive control circuit 200 includes: a posture detection processor 210, a timing controller 220, a touch drive circuit 230, and a level conversion circuit 240;

[0152] For example, such as Figure 5 As shown, sensors are also arranged parallel to each other on the bezel of the display device. These sensors include a transmitting unit and a receiving unit. For example, the sensors can be infrared sensors, ultrasonic sensors, etc. In practical applications, the specific type of sensor can be designed and determined according to the actual application environment, and is not limited here.

[0153] Let's take an infrared sensor as an example. The transmitting unit in the sensor continuously emits infrared signals, and the receiving unit in the sensor receives the reflected infrared signals. The infrared sensor collects information about the surrounding environment on one side of the display panel based on the time difference between emitting and receiving the reflected infrared signals, and then transmits the acquired information to the attitude detection processor.

[0154] When the posture detection processor 210 determines that there is a manipulator in front of the display panel 100, it acquires the distance between a set part of the manipulator and the display panel 100. When it determines that the distance meets a preset distance threshold, it outputs a display touch control signal. Based on the set part, it determines the target display sub-region as the fourth display sub-region XD4 from the first display sub-region XD1, the second display sub-region XD2, the third display sub-region XD3, the fourth display sub-region XD4, the fifth display sub-region XD5, and the sixth display sub-region XD6, and outputs information about the target display sub-region being the fourth display sub-region XD4.

[0155] For example, the posture detection processor determines whether the surrounding environment information contains a manipulator based on the surrounding environment information on one side of the display panel screen collected by the infrared sensor.

[0156] The timing controller 220 receives the display touch control signal and the information that the target display sub-area is the fourth display sub-area XD4, determines that the display touch mode is adopted, and in the next display frame, controls the fourth source drive circuit SIC4 corresponding to the fourth display sub-area XD4 to provide the first data voltage to the coupled data line DA4 during the display stage.

[0157] The touch driving circuit 230 receives the display touch control signal and performs a touch operation in the touch phase in the next display frame.

[0158] The level conversion circuit 240 receives the display touch control signal, making the output of the first control terminal EN1 an effective level signal and the output of the second control terminal EN2 an invalid level signal.

[0159] When the display touch mode is used, the target sub-area in the display panel has both a display stage and a touch stage, so that the target sub-area in the display panel can display the screen and also perform touch operations.

[0160] In this embodiment of the present disclosure, the posture detection processor is configured to, when it is determined that there is a manipulator in front of the display panel, obtain the distance between a set part of the manipulator and the display panel, and output a display control signal when it is determined that the distance does not meet a preset distance threshold.

[0161] The timing controller is configured to receive display control signals, determine the display mode to be used, and in the next display frame, control the source drive circuits corresponding to the remaining display sub-areas except the target display sub-area, and provide the second data voltage to the coupled data line during the display phase.

[0162] The touch drive circuit is configured to receive display control signals and not perform touch operations in the next display frame.

[0163] The level conversion circuit is configured to receive the display control signal, make the output of the first control terminal invalid, and make the output of the second control terminal valid.

[0164] For example, such as Figure 10 As shown, the following explanation will take the target display sub-region XD4 as an example. The manipulated object is the human body.

[0165] When the posture detection processor 210 determines that there is a human body in front of the display panel 100, it obtains the distance between a set part of the human body and the display panel 100. When it determines that the distance does not meet the preset distance threshold, it outputs a display control signal.

[0166] The timing controller 220 receives the display control signal and determines the display mode to be used. In the next display frame, it controls the first source driver circuit SIC1 corresponding to the first display sub-region XD1 to provide the second data voltage to the coupled data line DA1 during the display phase. It controls the second source driver circuit SIC2 corresponding to the second display sub-region XD2 to provide the second data voltage to the coupled data line DA2 during the display phase. It controls the third source driver circuit SIC3 corresponding to the third display sub-region XD3 to provide the second data voltage to the coupled data line DA3 during the display phase. It controls the fifth source driver circuit SIC5 corresponding to the fifth display sub-region XD5 to provide the second data voltage to the coupled data line DA5 during the display phase. It controls the sixth source driver circuit SIC6 corresponding to the sixth display sub-region XD6 to provide the second data voltage to the coupled data line DA6 during the display phase.

[0167] The touch drive circuit 230 receives the display control signal and does not perform a touch operation in the next display frame.

[0168] The level conversion circuit 240 receives the display control signal, makes the output of the first control terminal EN1 invalid, and makes the output of the second control terminal EN2 valid.

[0169] When in display mode, the display sub-areas of the display panel, excluding the target display sub-area, only have a display phase and no touch phase. Therefore, the display phase consumes the time required for the touch phase, thus lengthening the display phase time. The time required for the source drive circuit in the display sub-area (excluding the target display sub-area) to supply the second data voltage to the coupled data line during the display phase also increases. In other words, the charging time is longer. Therefore, the data voltage required in display mode is lower than that required in touch mode, resulting in reduced power consumption and lower display costs.

[0170] In the embodiments disclosed herein, such as Figure 10 As shown, the display panel 100 also includes: multiple grid lines GA;

[0171] The first gate drive circuit 130 is coupled to the timing controller 220 and multiple gate lines GA, and is configured to transmit the first scan signal to the first scan terminal CS1 through the multiple gate lines GA under the control of the timing controller 220.

[0172] The second gate drive circuit 140 is coupled to the timing controller 220 and multiple gate lines GA, and is configured to transmit the second scan signal to the second scan terminal CS2 through the multiple gate lines GA under the control of the timing controller 220.

[0173] The timing controller 220 is further configured to control the first gate drive circuit 130 to output a first scan signal, and to control the second gate drive circuit 140 to output a second scan signal.

[0174] For example, such as Figure 11 As shown, the level conversion circuit 240 includes: a logic circuit 241, an output circuit 242, a control circuit 243, and an over-temperature and over-current protection circuit 244. The logic circuit 241 is coupled to multiple control signal terminals (e.g., Te1, Te2, Te3, Te4, Te5, Te6 in the figure) and is configured to receive display touch control signals and convert them into two signals with opposite levels for output. The output circuit 242 includes multiple output sub-circuits LS1-LS13, all of which are coupled to the logic circuit 241. The system comprises two adjacent output sub-circuits forming a group (e.g., LS1 and LS2, LS3 and LS4, LS5 and LS6, LS7 and LS8, LS9 and LS10, and LS11 and LS12). Each group of output sub-circuits is coupled to the first output signal terminal V1 and the second output signal terminal V2, respectively, to receive two signals with opposite levels. One output sub-circuit in each group outputs a valid level signal, and another output sub-circuit outputs an invalid level signal. Additionally, one output sub-circuit (e.g., LS13) receives the reset input signal terminal REI and outputs a reset signal to the reset signal terminal RE. The control circuit 243, coupled to the logic circuit 241, controls the logic circuit 241 under the control of the signals from the first external signal terminal SAD and the second external signal terminal SCL. The over-temperature and over-current protection circuit 244 is coupled to the first output signal terminal V1 and the second output signal terminal V2. It is used to detect whether the current of the signal at the first output signal terminal V1 and the signal at the second output signal terminal V2 exceeds a preset current threshold and whether the temperature exceeds a preset temperature threshold. If so, an error signal is input to the error signal terminal Fa.

[0175] For example, the display panel 100 further includes a plurality of sensing electrodes coupled to the touch driving circuit 230 for sensing touch and transmitting touch signals to the touch driving circuit 230.

[0176] The touch driving circuit 230 is further configured to provide data signals to multiple sensing electrodes in response to touch signals for charging.

[0177] For example, such as Figure 10 and Figure 11 As shown, the first output signal terminal V1 is coupled to the first control terminal EN1 through a flip-chip film CCOF, and the second output signal terminal V2 is coupled to the second control terminal EN2 through a flip-chip film COF.

[0178] For example, such as Figure 11 As shown, the drive control circuit 200 also includes a PMIC module for providing the power required by the drive control circuit.

[0179] The following is based on Figure 10 and Figure 11 Taking the display device shown as an example, combined with Figures 12-17 The signal timing diagram shown describes the operation of the display device provided in the embodiments of this disclosure. The human body is used as an example to illustrate the manipulation.

[0180] For example, such as Figure 10 As shown, the following explanation will take the fourth display sub-region XD4 as an example. Specifically, the fourth display sub-region XD4 will be driven using a touch display mode, while the first display sub-region XD1, second display sub-region XD2, third display sub-region XD3, fifth display sub-region XD5, and sixth display sub-region XD6 will be driven using a display mode. The explanation will focus on the operation of the display device within one display frame.

[0181] When a human body is detected in front of the display panel, the distance between a set part of the human body and the display panel is obtained. When the distance meets a preset distance threshold, the display panel is driven in display touch mode. In the next display frame, the fourth display sub-area XD4 in the display panel is driven in display touch mode, and the first display sub-area XD1, the second display sub-area XD2, the third display sub-area XD3, the fifth display sub-area XD5, and the sixth display sub-area XD6 are driven in display mode.

[0182] like Figure 12 As shown, te4 represents the signal of the fourth control signal terminal Te4, en1 represents the signal of the first control terminal EN1, en2 represents the signal of the second control terminal EN2, da represents the data voltage signal, and cs1 represents the first scan signal of the first scan terminal CS1.
