DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The technical solutions in some embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present disclosure fall within the scope of protection of the present disclosure.

[0039] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular form "comprises" and the present participle form "comprising", are construed as open, inclusive meanings, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples", etc. are intended to indicate that the specific features, structures, materials or characteristics related to the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0040] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise stated, the meaning of "a plurality" is two or more.

[0041] When describing some embodiments, the expression "electrically connected" and its derivatives may be used. For example, when describing some embodiments, the term "electrically connected" may be used to indicate that two or more components have direct physical contact or electrical contact with each other.

[0042] "A and / or B" includes the following three combinations: only A, only B, and the combination of A and B.

[0043] The use of "configured to" herein means open and inclusive language, which does not exclude devices that are suitable for or configured to perform additional tasks or steps.

[0044] As used herein, "substantially" includes the recited value and an average value within an acceptable deviation range of the specific value, where the acceptable deviation range is determined by a person of ordinary skill in the art in view of the measurement being discussed and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system).

[0045] As used herein, "same layer" refers to a layer structure formed by using the same film-forming process to form a film layer for forming a specific pattern and then formed by using the same mask through a single patterning process. Depending on the different specific patterns, the single patterning process may include multiple exposure, development, or etching processes, and the specific patterns in the formed layer structure may be continuous or discontinuous, and these specific patterns may also be at different heights or have different thicknesses. In contrast, "different layer" refers to a layer structure formed by using the corresponding film-forming processes to form film layers for forming specific patterns and then formed by using the corresponding masks through patterning processes. For example, "two layer structures are arranged in different layers" means that the two layer structures are formed in corresponding process steps (film-forming process and patterning process).

[0046] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and regions is exaggerated for clarity. Accordingly, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Thus, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but include shape deviations resulting from, for example, manufacturing. For example, an etched region shown as rectangular will typically have curved features. Accordingly, the regions shown in the drawings are schematic in nature, and their shapes are not intended to depict the actual shape of regions of the device and are not intended to limit the scope of the exemplary embodiments.

[0047] In a first aspect, Figure 1 It shows a schematic circuit diagram of a display driving circuit provided by an embodiment of the present application in a first state, Figure 2 It shows a schematic circuit diagram of a display driving circuit provided by an embodiment of the present application in an ER1 state, as Figure 1 and Figure 2 shown, the display driving circuit includes: a first driving source signal line 10 and a plurality of second driving source signal lines 20.

[0048] Any two adjacent second driving source signal lines 20 are electrically connected, and the second driving source signal line 20 adjacent to the first driving source signal line 10 is electrically connected to the first driving source signal line 10.

[0049] In the first state, the driving voltage transmitted by the display driving circuit is transmitted through each second driving source signal line 20; in the second state, the driving voltage is transmitted through the other second driving source signal lines 20 except the target second driving source signal line 20 and the first driving source signal line 10; wherein, the target second driving source signal line 20 is a circuit with abnormal transmission.

[0050] It should be noted that the first state can be understood as the state where the display driving circuit can normally transmit the driving voltage, that is, each second driving source signal line 20 included in the display driving circuit has no damage or abnormality. The second state can be understood as the state where the display driving circuit cannot transmit the driving voltage normally, that is, one of the multiple second driving source signal lines 20 included in the display driving circuit has damage or abnormality. It should also be noted that the display driving circuit is used to transmit the driving voltage, and this driving voltage is used to make the blue sub-pixels, green sub-pixels, and red sub-pixels in the display panel display different brightnesses. When any one of the multiple second driving source signal lines 20 is damaged or abnormal, the corresponding sub-pixels in the display panel will have bright lines or dark lines, affecting the display effect of the display panel.

[0051] Based on this, in the embodiment of the present application, in the first state, the driving voltage transmitted by the display driving circuit can be transmitted through each second driving source signal line 20, that is, in the case where the display driving circuit can normally transmit the driving voltage, the driving voltage can be normally transmitted by each second driving source signal line 20. When a certain second driving source signal line 20 in the display driving circuit is damaged, the driving voltage can be transmitted through the other second driving source signal lines 20 except the target second driving source signal line 20 and the first driving source signal line 10. In this way, even when a certain second driving source signal line 20 included in the display driving circuit is damaged, it can still be normally transmitted, thereby avoiding the occurrence of poor display caused by damage or abnormality of the second driving source signal.

[0052] It should be noted that the above-mentioned first driving source signal line 10 can be understood as a standby source signal circuit, and it can not participate in the transmission of the driving voltage when the display driving circuit can normally transmit signals. The second driving source signal line 20 can be understood as a common signal source circuit, that is, when the display driving circuit can normally transmit signals, all of them need to participate in the transmission of the driving voltage.

[0053] It should also be noted that when there is a problem with the brightness and darkness of the display panel, it can be determined that a certain second driving source signal line 20 of the display driving circuit is damaged. In this case, the specific second driving source signal line 20 with problems can be found by using a microscope or a microelectronic device to control the display driving circuit.

[0054] As can be seen from the above embodiments, in the embodiments of the present application, since in the first state, the driving voltage transmitted by the display driving circuit is transmitted through each second driving source signal line 20, and in the second state, the driving voltage is transmitted through the other second driving source signal lines 20 except the target second driving source signal line 20 and the first driving source signal line 10, and since the target second driving source signal line 20 is a circuit with abnormal transmission, when the target second driving source signal line 20 has abnormal transmission, it can be transmitted through the other second driving source signal lines 20 except the target second driving source signal line 20 and the first driving source signal line 10, so that the display driving circuit can normally transmit the driving voltage, thereby avoiding the occurrence of display defects caused by damage or abnormality of the second driving source signal, improving the display effect of related display products, and ensuring that related display products can be normally displayed.

[0055] In some embodiments, in the second state, the driving voltage transmitted in the target second driving source signal line 20 is transmitted through the adjacent second driving source signal line 20, and the signal transmitted by the second driving source signal line 20 adjacent to the first driving source signal line 10 is transmitted through the first driving source signal line 10.

[0056] It should be noted that, assuming there are ten second drive source signal lines 20 in total for the second drive source signal lines 20, which can be the first second drive source signal line 20, the second second drive source signal line 20, the third second drive source signal line 20, the fourth second drive source signal line 20, the fifth second drive source signal line 20, the sixth second drive source signal line 20, the seventh second drive source signal line 20, the eighth second drive source signal line 20, the ninth second drive source signal line 20, and the tenth second drive source signal line 20 in sequence. Among them, the first second drive source signal line 20 is a circuit adjacent to the first drive source signal line 10. When the target second drive source signal line 20 is the fifth second drive source signal line 20, the drive voltage transmitted by the fifth second drive source signal line 20 is transmitted through the fourth second drive source signal line 20, the drive voltage transmitted by the fourth second drive source signal line 20 is transmitted through the third second drive source signal line 20, the drive voltage transmitted by the third second drive source signal line 20 is transmitted through the second second drive source signal line 20, and the drive voltage transmitted by the second second drive source signal line 20 is transmitted through the first drive source signal line 10. The sixth second drive source signal line 20, the seventh second drive source signal line 20, the eighth second drive source signal line 20, the ninth second drive source signal line 20, and the tenth second drive source signal line 20 are transmitted normally. In this way, through the above method, it can be ensured that the display drive circuit can transmit the drive voltage normally.

[0057] Optionally, the first drive source signal line 10 is connected to the first switch circuit 30, and each second drive source signal line 20 is connected to the second switch circuit 40; any two adjacent second drive source signal lines 20 are electrically connected through the second switch circuit 40, and the second drive source signal line 20 adjacent to the first drive source signal line 10 is electrically connected to the first drive source signal line 10 through the first switch circuit 30.

[0058] For the above electrical connection method, in the first state, the first switch circuit 30 is in the off state, and each second drive source signal line 20 including the second switch circuit 40 is in the on state; in the second state, the first switch circuit 30 is in the on state, the second switch circuit 40 connected to the target second drive source signal line 20 is in the off state, and the second switch circuits 40 connected to the other second drive source signal lines 20 except the target second drive source signal line 20 are in the on state.

[0059] It should be noted that in the first state, the first switch circuit 30 is in the off state, and each second driving source signal line 20 includes the second switch circuit 40 in the on state. That is, in the first state, the first driving source signal line 10 is in the off state, and the second driving source signal line 20 is in the on state. Therefore, when the display driving circuit can normally transmit the driving voltage, the driving voltage can be normally transmitted by each second driving source signal line 20. In the second state, the first switch circuit 30 is in the on state, the second switch circuit 40 connected to the target second driving source signal line 20 is in the off state, and the second switch circuits 40 connected to the other second driving source signal lines 20 except the target second driving source signal line 20 are in the on state. That is, in the second state, the first driving source signal line 10 is in the on state, and the other second driving source signal lines 20 except the target second driving source signal line 20 are in the on state. Therefore, when the target second driving source signal line 20 is abnormally transmitting, the driving voltage can be transmitted through the other second driving source signal lines 20 except the target second driving source signal line 20 and the first driving source signal line 10. In this way, by controlling the on / off of the first switch circuit 30 and the second switch circuit 40, it is possible to control in which driving signal source circuits the driving voltage is specifically transmitted, which is more beneficial for continuing to transmit through the first driving source signal line 10 when one of the second driving source signal lines 20 is damaged.

[0060] For the first switch circuit 30, in some embodiments, the first switch circuit 30 includes a first circuit 301 and a second circuit 302; the first circuit 301 is electrically connected to the first driving source signal line 10, and the second driving source signal line 20 adjacent to the first driving source signal line 10 is electrically connected to the first circuit 301 through the second circuit 302; in the first state, both the first circuit 301 and the second circuit 302 are in the off state, and in the second state, the first circuit 301 is in the off state and the second circuit 302 is in the on state.

[0061] It should be noted that the first circuit 301 is used to connect to the first driving source signal line 10, and the second circuit 302 is used to connect to the adjacent second driving source signal line 20. In this way, in the first state, both the first circuit 301 and the second circuit 302 can be in the off state, so that the first driving source signal is in an open circuit state and does not participate in the transmission of the driving voltage, and the electrical connection relationship with the adjacent second driving source signal line 20 is blocked. In the second state, the first circuit 301 can be in the off state and the second circuit 302 can be in the on state, that is, an electrical connection can be established between the second circuit 302 and the adjacent second driving source signal line 20, and then the driving voltage of the adjacent second driving source signal can be transmitted through the first driving source signal line 10.

[0062] For the second switching circuit 40, in some embodiments, the second switching circuit 40 includes a third circuit 401 and a fourth circuit 402; each second driving source signal line 20 is connected to a third circuit 401, and the third circuits 401 connected to any two adjacent second driving source signal lines 20 are electrically connected through the fourth circuit 402, and the third circuit 401 connected to the second driving source signal line 20 adjacent to the first driving source signal line 10 is electrically connected to the second circuit 302.

[0063] Specifically, in the first state, the third circuit 401 is in the conducting state and the fourth circuit 402 is in the non-conducting state; in the second state, the third circuit 401 and the fourth circuit 402 connected to the target second driving source signal line 20 are in the disconnected state, among the third circuit 401 and the fourth circuit 402 connected to the second driving source signal line 20 between the target second driving source signal line 20 and the first driving target circuit, the third circuit 401 is in the disconnected state and the fourth circuit 402 is in the conducting state, and among the third circuit 401 and the fourth circuit 402 connected to the remaining second driving source signal lines 20, the third circuit 401 is in the conducting state and the fourth circuit 402 is in the non-conducting state.

[0064] It should be noted that the third circuit 401 is used to electrically connect two adjacent second driving source signal lines 20 and the second circuit 302 of the first driving source signal line 10 adjacent to the second driving source signal line 20. In this way, not only are multiple second driving source signal lines 20 electrically connected to each other, but also the second driving source signal line 20 adjacent to the first driving source signal line 10 is electrically connected to the first driving source signal line 10. In this way, in the first state, the third circuit 401 can be in a conducting state, the fourth circuit 402 can be in a cut-off state, the third circuit 401 is in a conducting state, and the fourth circuit 402 is in a cut-off state. The driving voltage is transmitted through the third circuit 401 connected to each second driving source signal line 20. In the second state, the third circuit 401 and the fourth circuit 402 connected to the target second driving source signal line 20 are in an open state. Among the third circuit 401 and the fourth circuit 402 connected to the second driving source signal line 20 between the target second driving source signal line 20 and the first driving target circuit, the third circuit 401 is in an open state and the fourth circuit 402 is in a conducting state, that is, the driving voltage transmitted by the target second driving source signal line 20 is transmitted through the fourth circuit 402 connected to the adjacent second driving source signal line 20. By analogy from the target second driving source signal line 20 towards the first driving source signal line 10, the driving voltage transmitted by the second driving source signal line 20 between the target second driving source signal line 20 and the first driving target circuit is transmitted through the adjacent second driving source signal line 20, and the driving voltage transmitted by the second driving source signal line 20 adjacent to the first driving source signal line 10 is transmitted through the first driving source signal line 10. For the remaining second driving source signal lines 20, the driving voltage is normally transmitted by this second driving source signal line 20. Among them. The target second driving source signal line 20 can be as Figure 2 shown in A in

[0065] It should also be noted that the first circuit 301, the second circuit 302, the third circuit 401, and the fourth circuit 402 can all be set with metal-oxide-semiconductor (MOSFET) transistors, or can be insulated gate bipolar transistor (IGBT) transistors, or other devices with an electric control switch function. The embodiments of the present application do not limit this.

[0066] In some embodiments, the specific composition of the first drive source signal line 10 may be as follows: The first drive source signal line 10 includes a first latch 101, a first converter 102, and a first decoder 103. The second drive source signal line 20 includes a second latch 201, a second converter 202, and a second decoder 203. The first latch 101, the first converter 102, and the first decoder 103 are connected in series in sequence. The first switch circuit 30 is electrically connected to the first decoder 103. The second latch 201, the second converter 202, and the second decoder 203 are connected in series in sequence. The second switch circuit 40 is electrically connected to the second decoder 203.

[0067] It should be noted that the first converter 102 and the second converter 202 are mainly used to convert digital voltage into analog voltage. The first latch 101 and the second latch 201 mainly play the role of latching and locking. The first decoder 103 and the second decoder 203 are mainly used to read and clear fault codes so that the drive voltage can be transmitted normally.

[0068] Furthermore, the first drive source signal line 10 further includes a first amplifier 104, and the second drive source signal line 20 further includes a second amplifier 204. The first amplifier 104 is disposed between the electrical connection of the first switch circuit 30 and the first decoder 103. The second amplifier 204 is disposed between the electrical connection of the second switch circuit 40 and the second decoder 203.

[0069] It should be noted that the first amplifier 104 and the second amplifier 204 are mainly achieved by controlling energy through input signals. The power consumption of amplification is provided by energy, that is, the drive voltage input to the first decoder 103 can reproduce and enhance the signal through the first amplifier 104, and the drive voltage input to the second decoder 203 can reproduce and enhance the signal through the second amplifier 204.

[0070] Optionally, the first drive source signal line 10 further includes a first voltage protection circuit 105, and the second drive source signal line 20 further includes a second voltage protection circuit 205. The first voltage protection circuit 105 is electrically connected between the first amplifier 104 and the first switch circuit 30. The second voltage protection circuit 205 is electrically connected between the second amplifier 204 and the second switch circuit 40.

[0071] It should be noted that through the first power protection circuit and the second voltage protection circuit 205, the magnitude of the voltage can be controlled, thereby playing a role in increasing the driving force.

[0072] As can be seen from the above embodiments, in the embodiments of the present application, since in the first state, the driving voltage transmitted by the display driving circuit is transmitted through each second driving source signal line 20; in the second state, the driving voltage is transmitted through the other second driving source signal lines 20 except the target second driving source signal line 20 and the first driving source signal line 10, and since the target second driving source signal line 20 is a circuit with abnormal transmission, when the target second driving source signal line 20 has abnormal transmission, it can be transmitted through the other second driving source signal lines 20 except the target second driving source signal line 20 and the first driving source signal line 10, so that the display driving circuit can normally transmit the driving voltage, thereby avoiding the occurrence of poor display caused by damage or abnormality of the second driving source signal, improving the display effect of related display products, and ensuring that related display products can be normally displayed.

[0073] In a second aspect, an embodiment of the present disclosure further provides a display panel, which includes the display driving circuit according to any one of the first aspect embodiments. The beneficial effects of the display panel are the same as those of the above-mentioned display driving circuit, and the embodiments of the present disclosure will not elaborate on this.

[0074] In a third aspect, an embodiment of the present disclosure provides a display device, which includes the display panel described in the second aspect.

[0075] It should be noted that the display device may be a mobile display device such as a mobile phone, a tablet computer, a notebook computer, a handheld computer, an in-vehicle display device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc. The non-mobile display device may be a personal computer (PC), a television (TV), a teller machine or a self-service machine, etc. The embodiments of the present disclosure do not make specific limitations. The beneficial effects of the display device are the same as those of the above-mentioned display driving circuit, and the embodiments of the present disclosure will not elaborate on this.

[0076] It should be noted that the embodiments in this specification are all described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0077] Although alternative embodiments of the embodiments of the present application have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concepts. Therefore, the appended claims are intended to be construed to include alternative embodiments and all changes and modifications that fall within the scope of the embodiments of the present application.

[0078] Finally, it should also be noted that in this text, relational terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.
