[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The following description, in conjunction with the accompanying drawings, details a display module, detection method, and electronic device provided in this application through specific embodiments and application scenarios.

[0034] like Figure 1 and Figure 2 The diagram shown is a structural block diagram of a display module provided in an embodiment of this application. Figure 1 and Figure 2 As shown, the display module may include: a display driver module 100, a detection module 200, a source driver line 300, and a display module 400. The detection module includes multiple detection units.

[0035] The display driver module is connected to the display surface of the display module through multiple source driver lines to drive the display surface of the display module to display. The display driver module is connected to the detection module, and any two adjacent source driver lines are connected through a detection unit. The display driver module detects the continuity of the source driver lines by controlling the continuity of the detection unit.

[0036] It is worth noting that the source drive lines can be distributed within the display module, i.e. Figure 1 and Figure 2 In the AA region, multiple source drive lines can be evenly distributed within the display module, or distributed in other ways, depending on the actual application; this embodiment does not impose any limitations. The display driver module can output display content matching voltage values ​​to the display module via the source drive lines.

[0037] In other words, the display module is used to display the content output by the display driver module.

[0038] The source driving lines may include multiple ones, such as S1, S2, S3, etc. The number of source driving lines can be determined according to the size of the display module or other display requirements. This embodiment does not limit the number of source driving lines, but the actual application shall prevail.

[0039] This application discloses a display module including a display driving module, a detection module, source driving lines, and a display module. The detection module includes multiple detection units. The display driving module is connected to the display surface of the display module through multiple source driving lines to drive the display surface of the display module for display. The display driving module is connected to the detection module, and any two adjacent source driving lines are connected through detection units. The display driving module detects the continuity of the source driving lines by controlling the on / off state of the detection units. This application allows the display driving module to detect the continuity of the source driving lines by controlling the on / off state of the detection units, enabling analysis of the cause of vertical line defects without disassembly, thus improving detection efficiency.

[0040] like Figure 3 As shown, in one possible embodiment of this application, the display driving module includes a first control unit and a second control unit, any two adjacent source driving lines include an input driving line and an output driving line, and multiple detection units include a first detection unit 201 and a second detection unit 202. The first detection unit is disposed between any two adjacent source driving lines, and the second detection unit is disposed adjacent to the first detection unit.

[0041] The first control unit is connected to the control terminal of the first detection unit and is used to control the on / off state of the first detection unit; the second control unit is connected to the control terminal of the second detection unit and is used to control the on / off state of the second detection unit.

[0042] In other words, a detection unit is provided between any two source drive lines to detect the continuity of the two source drive lines. The continuity of the detection unit is controlled by a control unit connected to it.

[0043] It is worth noting that the first control unit and the second control unit are respectively connected to the control terminals of two adjacent detection units. For example, the first control unit (EVEN) can be connected to the control terminals of the detection units between the first and second source drive lines, and the detection units between the third and fourth source drive lines, etc., which are odd-numbered columns of detection units. Correspondingly, the second control unit (ODD) can be connected to the control terminals of the detection units between the second and third source drive lines, and the detection units between the fourth and fifth source drive lines, etc., which are even-numbered columns of detection units. In this embodiment, the detection units between the first and second source drive lines, and the detection units between the third and fourth source drive lines are all first detection units; the detection units between the second and third source drive lines, and the detection units between the fourth and fifth source drive lines are all second detection units. In other embodiments, other connection methods may also be used, depending on the actual application. This embodiment does not impose specific limitations.

[0044] In this embodiment, the first control unit and the second control unit can control the on / off state of the first detection unit and the second detection unit, thereby detecting the on / off state of the source drive line connected to the first detection unit and the second detection unit, and thus analyzing the cause of the vertical line defect, improving detection accuracy and efficiency.

[0045] In one possible embodiment of this application, the first detection unit includes a first transistor, the second detection unit includes a second transistor, the gate of the first transistor is connected to the first control unit, the drain of the first transistor is connected to the first source driving line, the source of the first transistor is connected to the second source driving line, the gate of the second transistor is connected to the second control unit, the drain of the second transistor is connected to the second source driving line, and the source of the second transistor is connected to the third source driving line.

[0046] In this embodiment, a transistor is used to connect two adjacent source drive lines, such that one source drive line is an input drive line used to input signals, and the other source drive line is an output drive line used to output signals. If an output signal can be detected on the output drive line when an input signal is input on the input drive line, it indicates that both source drive lines are conductive and there is no fault.

[0047] like Figure 3 As shown, when there are no display problems, EVEN and ODD are pulled high by default, keeping all detection units (transistors) in the off state, and the screen can display normally. When a display problem occurs and the system enters detection mode, EVEN and ODD can individually control the gate of each transistor to a low level (i.e., turn on the transistor) to achieve different circuit combinations, thereby identifying the source drive line where the fault occurred. Figure 3 In this system, each source driver line has the ability to distinguish input levels. One of two adjacent source driver lines is configured as the input mode and the other as the output mode.

[0048] This embodiment is described using the example of the EVEN circuit being pulled low, the ODD circuit being pulled high, and the S5 circuit being abnormally open, as shown below.

[0049] The first step is to configure S5 as an output, and at this time S5 and S6 are connected. When the driver S5 outputs high and low levels (e.g., low level 1.2V and high level 5V) in a cycle, if S6 can read the corresponding signal change, it means that both S5 and S6 are normal. If no signal change is read, there are two possibilities: S5 output is abnormal, or S6 input is abnormal.

[0050] The second step is to pull EVEN high and ODD low for a second judgment. At this time, S5 and S4 are connected, and S6 and S7 are connected. Repeat the input / output and level configuration of the first step. If S4 can read the high and low level changes, it proves that the output of S5 is normal. Otherwise, S5 is abnormal. Similarly, if S6 can read the high and low level changes of S7, it proves that the input of S6 is normal. Otherwise, S6 is abnormal.

[0051] This embodiment sets the two source driver lines as one input and one output, requiring only half of the source driver lines to be configured for input / output, while the other half remains functional as output. This reduces the number of dual-function source driver lines by half. In other embodiments, different time-division multiplexing methods can be used to further simplify the detection logic and detection circuit. These embodiments are not described in detail here; the actual application shall prevail.

[0052] Alternatively, the transistor can be a thin-film transistor (TFT).

[0053] like Figure 4 As shown, in one possible embodiment of this application, the display driving module includes a first control unit, a second control unit, and an analog-to-digital conversion unit. Any two adjacent source driving lines are output driving lines. The detection module also includes a connection unit. Multiple detection units include a third detection unit 203 and a fourth detection unit 204. The third detection unit is disposed between any two adjacent source driving lines, and the fourth detection unit is disposed adjacent to the third detection unit. The first end of the connection unit is connected to the analog-to-digital conversion unit, and the second end of the connection unit is connected to any one of the source driving lines. The control end of the connection unit is connected to the first control unit, and the first control unit controls the on / off state of the connection unit. When the connection unit is on, the analog-to-digital conversion unit inputs a signal to the source driving line. The first control unit is connected to the control end of the third detection unit to control the on / off state of the third detection unit. The second control unit is connected to the control end of the fourth detection unit to control the on / off state of the fourth detection unit.

[0054] In other words, in addition to setting two adjacent source driving lines as one input and one output in the above embodiments, the input terminal can also be set by setting an analog-to-digital conversion unit, and all source driving lines can be outputs. This can achieve detection without changing the function of the source driving lines themselves, reducing circuit complexity and wafer area, thereby saving costs.

[0055] In this embodiment, the analog-to-digital conversion unit can be the first analog-to-digital conversion unit 110, that is... Figure 4In the D1 of the above, the corresponding connecting unit can be the first connecting unit 205. That is, the input signal is through the first analog-to-digital conversion unit and then output to each source driving line through the first connecting unit to detect the continuity of each source driving line. If each source driving line can output a signal, it means that the source driving lines are normal. If a certain source driving line cannot detect an output signal, it means that the source driving line is abnormal.

[0056] In other embodiments, a second analog-to-digital conversion unit 120 may also be included, i.e. Figure 4 In the D2 of the module, the detection module may also include a second connecting unit 206, which has the same function as the first analog-to-digital conversion unit and the first connecting unit, but is set in a different position. Both can also be set, i.e., D1 and D2, with both the first connecting unit and the second connecting unit set. This can be determined according to the actual application, and this embodiment does not make a specific limitation.

[0057] In one possible embodiment of this application, the third detection unit includes a third transistor, the fourth detection unit includes a fourth transistor, the connection unit includes a fifth transistor, the gate of the fifth transistor is connected to the first control unit, the drain of the fifth transistor is connected to the analog-to-digital conversion unit, the source of the fifth transistor is connected to the first source driving line, the gate of the third transistor is connected to the first control unit, the drain of the third transistor is connected to the first source driving line, the source of the third transistor is connected to the second source driving line, the gate of the fourth transistor is connected to the second control unit, the drain of the fourth transistor is connected to the second source driving line, and the source of the fourth transistor is connected to the third source driving line.

[0058] In this embodiment, transistors are used to connect two adjacent source drive lines, and to connect the analog-to-digital converter (ADC) unit to each source drive line. The ADC unit is used to input signals, and all source drive lines are output drive lines used to output signals. If an output signal can be detected on all output drive lines when the ADC unit is inputting a signal, it indicates that all source drive lines are conducting and there is no fault.

[0059] In this embodiment, all detection functions can be accomplished by individually setting either D1 or D2. By simultaneously pulling EVEN and ODD low, all transistors are turned on, shorting all source driver lines. Each source driver line is sequentially set to high or low level, or a specific voltage, and all source driver lines can be detected through either D1 or D2. This embodiment can not only detect vertical line anomalies but also pinpoint the specific abnormal source driver line. For investigating thousands of source driver lines in a plane, it can save significant manpower and resources. Furthermore, by collecting data on the distribution of all anomalies, risk points can be identified for subsequent display modules, allowing for design improvements.

[0060] The circuit in this embodiment can not only detect whether there is output, but also detect whether the output voltage of the source drive line is accurate. Inaccurate source drive lines can be adjusted individually to avoid display quality problems caused by circuit aging or impedance changes during use.

[0061] It is worth noting that the design logic and circuit topology of the control source drive lines in this embodiment can be adopted, but other methods can also be used, such as odd-numbered connection and even-numbered connection, and other methods that form a loop by setting intervals between the source drive lines. The specific implementation of this application will not be described in detail, and the actual application shall prevail.

[0062] In one possible embodiment of this application, the display module may include a display surface 420 and a bending portion 410, and the detection module may include a first detection submodule 210 disposed within the display driving module, a second detection submodule 220 disposed between the display driving module and the bending portion, a third detection submodule 230 disposed between the bending portion and the display surface, and a fourth detection submodule 240 disposed on the display side of the display surface. The first detection submodule, the second detection submodule, the third detection submodule, and the fourth detection submodule each include multiple detection units.

[0063] The first detection submodule is used to detect the continuity of the source driving lines within the display driving module; the second detection submodule is used to detect the continuity of the source driving lines between the display driving module and the bending section; the third detection submodule is used to detect the continuity of the source driving lines within the bending section; and the fourth detection submodule is used to detect the continuity of the source driving lines within the display surface.

[0064] In other words, multiple detection sub-modules can be set at different locations inside the electronic device to detect the continuity of the source drive lines in different parts, so as to accurately detect the fault location of the source drive lines and further improve detection accuracy and efficiency. For example, if the source drive line abnormality is caused by electrostatic discharge (ESD), all detection sub-modules can detect the abnormality; if the abnormality is caused by a crack in the bending area, the third and fourth detection sub-modules can detect the abnormality, while the detection results of the first and second detection sub-modules are normal; if the source drive line in the display drive module is abnormal, the first, second, third, and fourth detection sub-modules can all detect the abnormality; if the source drive line between the display drive module and the bending part is abnormal, the first detection sub-module detects it normally, while the second, third, and fourth detection sub-modules can all detect the abnormality; if the source drive line in the display surface is abnormal, the first, second, and third detection sub-modules detect it normally, while the fourth detection sub-module can detect the abnormality.

[0065] In other embodiments, detection submodules can also be set in other parts to detect abnormalities in other parts. This embodiment will not elaborate on this, depending on the actual application.

[0066] like Figure 5 As shown, in one possible embodiment of this application, the transistor may include: a substrate layer 601, a buffer layer 602, a doped layer 603, a gate insulating layer 604, a planarization layer 605 and an encapsulation layer 606 stacked sequentially.

[0067] The doped layer 603 includes a P-type doped layer 6031 and an N-type doped layer 6032; the gate insulating layer includes a gate 6041, and source 6042 and drain 6043 located on both sides of the gate; the planarization layer includes a first via 6051 located above the source 6042 and a second via 6052 located above the drain 6043. The first via 6051 is used to connect to the first analog-to-digital converter 110 and the second analog-to-digital converter 120, and the second via 6052 is used to connect to the second end of the source drive line 300.

[0068] In this embodiment, both the source 6042 and the drain 6043 can use metal layer 1, such as molybdenum-aluminum-molybdenum (Mo / Al / Mo), or metal layer 2, such as titanium-aluminum-titanium (Ti / Al / Ti). A photomask corresponding to either metal layer 1 or metal layer 2 can be used to design a connection to the source drive line 300 via the first via 6051 and the second via 6052. The transistor provided in this embodiment requires no additional photomask.

[0069] This application also provides an electronic device, including the display module provided in any of the above embodiments. It achieves the same technical effects, and to avoid repetition, it will not be described again here.

[0070] like Figure 6 As shown, this application provides a detection method applied to the electronic device provided in the above embodiments. Figure 6 As shown, the detection method may include the contents shown in S601 to S602.

[0071] In S601, when the display of an electronic device malfunctions, the display driver module controls the activation of the detection unit in the detection module.

[0072] In S602, the continuity of the source drive line is detected based on the conduction of the detection unit to determine the source drive line that has malfunctioned.

[0073] In other words, when a problem occurs in the display, such as a faulty vertical line, the display driver module controls the conduction of the detection unit in the detection module, and then detects the continuity of each source driver line to determine the source driver line that is faulty.

[0074] In this embodiment, when a display malfunctions in the electronic device, the display driver module controls the conduction of the detection unit in the detection module. Then, based on the conduction of the detection unit, the continuity of the source drive line is detected to identify the faulty source drive line. This embodiment allows the display driver module to detect the continuity of the source drive line by controlling the conduction of the detection unit, enabling analysis of the cause of vertical line defects without disassembly, thus improving detection efficiency.

[0075] In one possible embodiment of this application, the display driver module controls the on / off state of the detection unit in the detection module, which may include: controlling the conduction of the detection unit through the first control unit and the second control unit in the display driver module.

[0076] Accordingly, detecting the continuity of the source driving line based on the conduction of the detection unit can include: setting any two adjacent source driving lines as input driving line and output driving line based on the conduction of the detection unit, and detecting the continuity of the source driving line, wherein the input driving line is used for input signal and the output driving line is used for output signal.

[0077] In other words, a detection unit is provided between any two source drive lines to detect the continuity of the two source drive lines. The continuity of the detection unit is controlled by a control unit connected to it.

[0078] It is worth noting that the first control unit and the second control unit are respectively connected to the control terminals of two adjacent detection units. For example, the first control unit (EVEN) can be connected to the control terminals of the detection units between the first and second source drive lines, and the detection units between the third and fourth source drive lines, etc., which are odd-numbered columns of detection units. Correspondingly, the second control unit (ODD) can be connected to the control terminals of the detection units between the second and third source drive lines, and the detection units between the fourth and fifth source drive lines, etc., which are even-numbered columns of detection units. In this embodiment, the detection units between the first and second source drive lines, and the detection units between the third and fourth source drive lines are all first detection units; the detection units between the second and third source drive lines, and the detection units between the fourth and fifth source drive lines are all second detection units. In other embodiments, other connection methods may also be used, depending on the actual application. This embodiment does not impose specific limitations.

[0079] In this embodiment, the on / off state of the detection unit can be controlled by the first control unit and the second control unit, thereby detecting the on / off state of the source drive line connected to the detection unit, and analyzing the cause of the vertical line defect, thus improving the detection accuracy and efficiency.

[0080] In one possible embodiment of this application, the display driver module controls the on / off state of the detection unit in the detection module, which may include: controlling the conduction of the detection unit through the first control unit and the second control unit in the display driver module;

[0081] Accordingly, based on the conduction of the detection unit, the on / off state of the source driving line can be detected by: based on the conduction of the detection unit, inputting a detection signal through the analog-to-digital conversion unit in the display driving module, and sequentially controlling each source driving line as an output driving line to detect the on / off state of each source driving line, wherein the output driving line is used to output the detection signal.

[0082] In other words, in addition to setting two adjacent source driving lines as one input and one output in the above embodiments, the input terminal can also be set by setting an analog-to-digital conversion unit, and all source driving lines can be outputs. This can achieve detection without changing the function of the source driving lines themselves, reducing circuit complexity and wafer area, thereby saving costs.

[0083] In this embodiment, the analog-to-digital conversion unit can be a first analog-to-digital conversion unit, i.e. Figure 4 D1 in the first analog-to-digital converter unit is used to input signals and output signals to each source driver line to detect the continuity of each source driver line. If each source driver line can output a signal, it means that the source driver lines are normal. If a source driver line cannot output a signal, it means that the source driver line is abnormal.

[0084] In other embodiments, a second analog-to-digital conversion unit may also be included, i.e. Figure 4 D2 in the first analog-to-digital converter has the same function as the first analog-to-digital converter, but the position is different. Both can also be set, namely D1 and D2, which can be determined according to the actual application. This embodiment does not make a specific limitation.

[0085] In one possible embodiment of this application, the detection method may further include: placing a detection unit within a display driving module to detect the continuity of source driving lines within the display driving module; and / or placing a detection unit between the display driving module and the bend to detect the continuity of source driving lines between the display driving module and the bend; and / or placing a detection unit between the bend and the display surface to detect the continuity of source driving lines within the bend; and / or placing a detection unit on the display side of the display surface to detect the continuity of source driving lines within the display surface.

[0086] In other words, multiple detection units can be set at different locations inside the electronic device to detect the continuity of the source drive line in different parts, so as to accurately detect the fault location of the source drive line and further improve detection accuracy and efficiency.

[0087] In other embodiments, detection units can also be set in other locations to detect abnormalities in other locations. This embodiment will not elaborate on this, depending on the actual application.

[0088] like Figure 7 As shown, this application provides a detection device applied to the electronic equipment provided in the above embodiments. Figure 7 As shown, the detection device includes a conduction module 701 and a detection module 702.

[0089] The conduction module 701 is used to control the conduction of the detection unit in the detection module when the display of the electronic device malfunctions; the detection module 702 is used to detect the continuity of the source drive line based on the conduction of the detection unit, so as to determine the source drive line that has malfunctioned.

[0090] In this embodiment, the conduction module 701 first controls the conduction of the detection unit in the detection module when the display of the electronic device malfunctions. Then, the detection module 702 detects the continuity of the source drive line based on the conduction of the detection unit to determine the faulty source drive line. This embodiment allows the display driver module to detect the continuity of the source drive line by controlling the continuity of the detection unit, enabling analysis of the cause of vertical line defects without disassembly, thus improving detection efficiency.

[0091] It is worth noting that the electronic device may include a display module, which includes a display driver module, and the display driver module may include the conduction module in this embodiment.
