Description

Technical Field

[0001] The present invention relates to the field of display panel design, and in particular to a wiring method and a wiring device for a display panel. Background Art

[0002] With the development of science and technology, display devices are widely used in many electronic products, such as mobile phones, tablet computers, watches, cars, etc. The display panel has a display area and a peripheral area that are adjacent to each other. The display area is provided with array-arranged thin-film transistors and gate lines, data lines, etc., and the peripheral area is provided with electronic components and signal leads connected between the electronic components and between the electronic components and the display area. In the current display panel design, the electronic components in the peripheral area may include a driver chip IC and a flexible circuit board FPC. The flexible circuit board FPC receives external signals and transmits them to the driver chip IC via signal leads. The driver chip IC then transmits the received signals to the display area via other signal leads. In actual operation, the lines in the display area usually present large areas, high repeatability and highly regular characteristics, and can be drawn using drawing-assisted design tools. However, the lines in the peripheral areas, such as when designing the wiring between the driver chip IC and the flexible circuit board FPC, due to considerations such as the size and number of pins of the driver chip IC and the flexible circuit board FPC, actual circuit drawing often encounters small areas and irregular designs, which requires a lot of working time for data comparison and calculation. Drawing-assisted design tools cannot be used for this, and wiring drawing is usually done manually instead. However, manual drawing is inefficient and prone to errors, which is a problem that needs to be solved urgently. Summary of the invention

[0074] In order to solve the problem of wiring design between components in display panels (especially the peripheral area of ​​display panels), because actual circuit drawing often encounters small areas and irregular designs, it takes a lot of time to compare and calculate data, and manual wiring drawing is inefficient and prone to errors, please refer to Figure 1 , Figure 2 and Figure 5 , Figure 1 A schematic diagram of a wiring method for a display panel according to an embodiment of the present invention is shown. Figure 2 A schematic diagram of a specification document in one embodiment of the present invention is shown. Figure 5A schematic diagram of automatically generating a wiring pattern between signals of a first component and a second component according to a specification document in one embodiment of the present invention is shown. The present invention proposes a wiring method for a display panel, wherein the display panel has an adjacent display area and a peripheral area, wherein the peripheral area is used to set a wiring pattern 200, a first component 1, and a second component 2, etc. When the display panel is actually manufactured, the wiring pattern 200 is formed in the peripheral area according to a preliminary wiring design style, and the first component 1 and the second component 2 are bonded to both ends of the wiring pattern 200, and each pin of the input end of the first component 1 (hereinafter referred to as the first pin) is bonded to one end of the wiring pattern 200, and each pin of the output end of the second component 2 (hereinafter referred to as the second pin) is bonded to the other end of the wiring pattern 200, and the electrical connection between the first component 1 and the second component 2 is realized by the wiring pattern 200, so as to facilitate subsequent signal transmission.

[0075] In one embodiment, the first component 1 is a driver chip (IC), and the second component 2 is a flexible printed circuit (FPC). The driver chip (IC) is arranged between the display area and the flexible printed circuit (FPC). After the flexible printed circuit (FPC) receives an external signal, it transmits it to the driver chip (IC) via a wiring pattern 200. The driver chip (IC) then transmits the received signal to the display area via other wirings. The first component 1 and the second component 2 in the present invention are not limited to this.

[0076] In one embodiment, each first pin of the input end of the first component 1 is used to receive multiple different signals, and each second pin of the output end of the second component 2 is used to output the multiple different signals. In actual operation, the number and pin spacing of the first pins on the first component 1 are different from the number and pin spacing of the second pins on the second component 2, so that each first pin needs to form a signal correspondence relationship with each second pin to achieve normal transmission of the aforementioned multiple different signals. The wiring pattern 200 can be designed to include multiple wirings according to the signal correspondence relationship to meet the corresponding electrical connection between each first pin and each second pin and transmit the aforementioned multiple different signals.

[0077] In the wiring design stage, the signal correspondence relationship between the first component 1 and the second component 2 can be formed according to the general signal correspondence rule, and the signal correspondence relationship is included in the specification document. The wiring method of the display panel further includes the following steps:

[0078] Step S1: automatically generating a wiring pattern 200 for electrically connecting a first component 1 and a second component 2 according to a specification document.

[0079] In one embodiment, step S1 further comprises:

[0080] Step S11: automatically detect whether there is an abnormality in the signal correspondence relationship between the first component 1 and the second component 2, if not, execute step S12;

[0081] Step S12: defining a wiring drawing logic and generating a wiring drawing instruction according to the signal correspondence between the first component 1 and the second component 2; and

[0082] Step S13: Generate the wiring pattern 200 in the wiring drawing software according to the wiring drawing instruction.

[0083] In this embodiment, before using the wiring drawing software to generate the wiring pattern 200, it is detected whether there is any abnormality in the signal correspondence between the first component 1 and the second component 2. In this way, errors in the signal correspondence between the first component 1 and the second component 2 in the specification document can be discovered in advance, avoiding tracing back the error after generating the wiring pattern 200, thereby improving the efficiency of wiring design.

[0084] In one embodiment, after completing step S1 to generate the wiring pattern 200, step S2 may be further executed: identifying whether the wiring pattern 200 meets the first specification requirement of the specification document. If the wiring pattern 200 generated in step S1 meets the first specification requirement, the final wiring pattern 200 is obtained. If the wiring pattern 200 generated in step S1 does not meet the first specification requirement, step S21 is executed: adjusting the signal correspondence between the first component 1 and the second component 2 and updating the specification document, then returning to step S1, and then executing step S2, and so on, until the generated wiring pattern 200 meets the first specification requirement.

[0085] In one embodiment, the first specification requirement may include the space requirement occupied by the wiring pattern 200, the impedance value requirement of the wiring corresponding to each pin of the first component 1 and the second component 2, and other wiring design requirements such as those specified by the driver chip manufacturer and the flexible circuit board manufacturer, but the present invention is not limited thereto.

[0086] In one embodiment, the wiring drawing software may be Laker, and the wiring drawing instructions generated according to the wiring drawing logic also correspond to the drawing instructions of the Laker software. In other embodiments, the wiring drawing software may also be other software, and the present invention is not limited thereto.

[0087] In one embodiment, in step S12, the designer may first write a programming language based on the specification document (specifically, for example, the signal correspondence between the first component 1 and the second component 2), define the wiring drawing logic and generate text that can be executed in the wiring drawing software environment. For example, the specification document presents an Excel operation interface, and the designer uses VBA (Visual Basic for Applications) syntax to write a drawing logic definition (i.e., wiring drawing logic) based on the signal correspondence between the first component 1 and the second component 2 in the Excel operation interface, including the circuit connection method between the first component 1 and the second component 2, and automatically generates a TCL text (i.e., regarded as a wiring drawing instruction); then the generated TCL text is executed in the wiring drawing software (such as the aforementioned Laker) environment to generate a wiring pattern 200 (corresponding to step S13). In other embodiments, the specification document is not limited to the Excel operation interface, and the programming language is not limited to VBA.

[0088] In the present invention, a programming language can be written according to the signal correspondence in the specification document to automatically generate text that can be executed in the wiring drawing software environment, and when the generated wiring pattern 200 does not meet the first specification requirements, the signal correspondence between the first component 1 and the second component 2 can be flexibly adjusted, and the drawing can be redrawn for verification, without manually drawing and adjusting the irregular wiring pattern one by one in the wiring drawing software. After using the wiring design method of the display panel of the present invention, the wiring pattern 200 corresponding to the adjustment scheme can be quickly generated, reducing the generation time of the wiring pattern 200 and speeding up the wiring design speed in the display panel.

[0089] In one embodiment of the wiring method for a display panel of the present invention, the step of automatically detecting whether there is an abnormality in the signal correspondence relationship between the first component 1 and the second component 2 in the specification document in step S11 further includes:

[0090] Step S111: Detect whether the total number of signals of the first component 1 and the second component 2 corresponds to each other; and

[0091] Step S112: Detect whether the parameters between the signals of the first component 1 and the second component 2 correspond correctly.

[0092] In one embodiment, if Figure 2As shown, the total number of signals of the first component 1 is calculated by numbering each first pin of the first component 1 and each second pin of the second component 2, and the number of the first pin and the number of the second pin may be different. For example, the first pin numbered 27 in the first component 1 is called pin number 27 (hereinafter the same) and has a corresponding signal name DummyR1, and the corresponding number (that is, the number of second pins in the second component 2 that need to be connected) has no specified value, then pin number 27 is regarded as one signal; for another example, the corresponding signal names of pin numbers 29 to 32 of the first component 1 are all VGL, and the corresponding number has no specified value, then pin numbers 29 to 32 can be regarded as one signal. In actual operation, if the corresponding signal names of multiple pin numbers are the same and the corresponding number has no specified value, they can be regarded as one signal; for another example, the pin number 37 of the first component 1 has a corresponding signal name VCC, and the corresponding number is 2, which means that pin number 37 needs to be connected to 2 second pins in the second component 2, then pin number 37 is regarded as two signals. According to the rule, the pin numbers of the first component 1 are traversed and added to obtain the total number of signals. The same calculation method can be used for the second component 2. The total number of signals of the first component 1 and the second component 2 should correspond, for example, the same or the total number of signals of the first component 1 is less than the total number of signals of the second component 2. If the total number of signals does not comply with the rule, the error is highlighted and displayed in the specification document.

[0093] See also Figures 2 to 4 , Figure 3 A schematic diagram of a specification document in another embodiment of the present invention is shown. Figure 4 A schematic diagram of a specification document in another embodiment of the present invention is shown. In an embodiment of the wiring method of the display panel of the present invention, the signals corresponding to the pins of the first component 1 and the second component 2 have the same name as a group of corresponding signals 100. The signal corresponding to the first pin of the first component 1 in the group of corresponding signals 100 is recorded as a first signal 110, and the signal corresponding to the second pin of the second component 2 is recorded as a second signal 120. Figure 2 Taking a group of corresponding signals 100 in the dashed box as an example, the first signal 110 (VCC) corresponds to a first pin (pin number 37) in the first component 1, and the corresponding number of the first signal 110 is 2, then the first pin corresponding to the first signal 110 (VCC) is connected to the two second pins (pin numbers 19 and 20 in this embodiment) in the second component 2, and the value "1" in the line connection indicates that the first signal 110 (VCC) and the second signal 120 (VCC) in this group of corresponding signals are connected. Among them, the step of detecting whether the parameter correspondence between the signals of the first component 1 and the second component 2 is correct further includes:

[0094] Step S1121: Detect whether the names and / or types of the first signal 110 and the second signal 120 in each set of corresponding signals 100 are the same. Figure 2 As shown, when detecting a set of corresponding signals 100, only the names of the first signal 110 and the second signal 120 are detected to see whether they are the same. In one embodiment, Figure 4 As shown, when detecting a set of corresponding signals 100, the names and types of the first signal 110 and the second signal 120 are simultaneously detected. In other embodiments, the first component 1 may also support multiple signals with the same name but different types. In this case, the names and types of the multiple signals corresponding to the second component 2 need to be the same as the signals corresponding to the first component 1, otherwise the signal correspondence error will be identified.

[0095] Step S1122: Detect whether the corresponding number of the first signal 110 in each set of corresponding signals 100 corresponds to the number of the second signal 120; and / or detect whether the corresponding number of the second signal 120 in each set of corresponding signals 100 corresponds to the number of the first signal 110. In one embodiment, if Figure 2 As shown, the corresponding number of the first signal 110 in a group of corresponding signals 100 in the dotted frame is 2, which means that the first signal 110 in the group of corresponding signals occupies one pin (pin number 37) of the first component 1, and the corresponding number of the second signal 120 connected thereto is 2, which means that the second signal 120 in the group of corresponding signals occupies two pins (pin numbers 19 and 20) of the second component 2. At this time, it is determined that the corresponding number of the first signal 110 corresponds to the number of the second signal 120; Figure 3 In the illustrated embodiment, the corresponding number of the second signal 120 in a group of corresponding signals 100 in the dotted frame is 4, which means that the second signal 120 in the group of corresponding signals occupies one pin (pin number 17) of the second component 2, and the corresponding number of the first signal 110 connected thereto is 4. Then, the number of the first signal 110 in the group of corresponding signals is 4, occupying four pins (pin numbers 29 to 32) of the first component 1. At this time, it is determined that the corresponding number of the second signal 120 corresponds to the number of the first signal 110.

[0096] In other embodiments, the format of the specification document can also be checked. For example, if the pin number is recorded but the signal name is empty, the error can be highlighted and displayed in the specification document. In one embodiment, the specification document presents an Excel operation interface, and the designer can set the comparison logic or write a programming language in the specification document to compare the aforementioned signal correspondence.

[0097] See also Figure 1 and Figure 5In one embodiment of the wiring method of the display panel of the present invention, the step S12 of defining the wiring drawing logic according to the signal correspondence between the first component 1 and the second component 2 further includes:

[0098] Step S121: Determine the signal position starting point of the first component 1 and the second component 2 according to the wiring drawing origin. In this embodiment, the wiring drawing origin is the lower left corner vertex of the binding area for the second component 2.

[0099] Step S122: According to the number and size of the pins corresponding to each signal in the first component 1 and the second component 2, the drawing positions and widths of the first pads 11 corresponding to the first component 1 and the second pads 12 corresponding to the second component 2 are determined in the order of the signal numbers according to the corresponding relationship between the first component 1 and the second component 2. In one embodiment, the aforementioned wiring drawing origin is the lower left corner vertex of the first second pad 12 from left to right.

[0100] Step S123 : determining the connection relationship between each first bonding pad 11 and each second bonding pad 12 according to the signal correspondence relationship between the first component 1 and the second component 2 .

[0101] As mentioned above, the first specification requirement may include the space requirement occupied by the wiring pattern 200, the impedance value requirement of the wiring corresponding to each pin of the first component 1 and the second component 2, etc. In one embodiment of the wiring method of the display panel of the present invention, the step of identifying whether the wiring pattern 200 meets the first specification requirement in step S2 further includes: detecting whether the wiring pattern 200 meets the space requirement between the first component 1 and the second component 2; and / or calculating whether the impedance value of the electrical connection according to the corresponding relationship between the signals of the first component 1 and the second component 2 meets the impedance value requirement in the specification document.

[0102] In one embodiment, when the electrical connection does not meet the impedance value requirement, that is, the impedance value of the wiring formed by the pins on the first component 1 and the second component 2 according to the signal correspondence (each wiring includes at least a first pad 11, a second pad 12 and a connection between the two) is greater than the impedance value requirement in the specification document (such as Figure 3 As shown in the figure, the upper limit of the electrical connection impedance value corresponding to the four pins numbered 29 to 32 on the first component 1 is 5 ohms). After the wiring pattern 200 is drawn, the actual electrical connection impedance value will be calculated and highlighted in the specification document when it does not meet the impedance value requirement, prompting the relevant designer to adjust the design to reduce the electrical connection impedance value. In addition, if it is detected that the generated wiring pattern 200 does not meet the space requirements, it will also be highlighted in the specification document.

[0103] In one embodiment, after the wiring drawing software generates the wiring pattern 200 according to the wiring drawing instruction, the wiring drawing software automatically calculates the impedance value of each wiring in the wiring pattern 200, the space occupied by the wiring pattern 200, etc., and returns the calculation results to the specification document. The calculation results are compared with the first specification requirements, and highlight marks are used at abnormal locations to remind the designer. The designer can adjust the signal correspondence between the first component 1 and the second component 2 in the specification document in combination with the highlight marks in the specification document, and then re-execute step S1 (including adjusting the written program language according to the adjusted signal correspondence, redefining the wiring drawing logic, etc.) and step S2 until the generated wiring pattern 200 meets the first specification requirements. In this process, automatic re-drawing verification is achieved through specification documents, program language writing, etc., without the need to manually draw and adjust this irregular wiring pattern one by one in the wiring drawing software, thereby improving the speed of wiring design and reducing the error rate.

[0104] In one embodiment of the wiring method of the display panel of the present invention, when the wiring pattern 200 does not meet the first specification requirement, the signals corresponding to the pin numbers on the first component 1 and the second component 2 that are identified as not meeting the first specification requirement are recorded as target signals, and the step of adjusting the signal correspondence relationship between the first component 1 and the second component 2 further includes:

[0105] The target signal in the first component 1 is connected in parallel with a signal having the same name and type in the first component 1 ; and / or the target signal in the second component 2 is connected in parallel with a signal having the same name and type in the second component 2 .

[0106] In one embodiment, the impedance value of the wiring corresponding to a group of corresponding signals 100 is calculated by confirming the area of ​​the closed figure (i.e., the corresponding wiring) composed of the first pad 11, the second pad 12, and the connection between the first signal 110 and the second signal 120 in the group of corresponding signals 100 according to the generated wiring pattern 200, and determining the impedance value of the wiring corresponding to the group of corresponding signals 100 in combination with the designed thickness of the wiring pattern 200. The impedance value of the wiring corresponding to the group of signals is inversely proportional to the cross-sectional area of ​​the wiring pattern 200 at this location. After the target signal is connected in parallel with a signal of the same name and type, the width of the closed figure composed of the connection between the first signal 110 and the second signal 120 in the group of signals will be increased, and the cross-sectional area at this location will be increased, thereby reducing the impedance value of the group of signals.

[0107] In one embodiment, there are two operating modes for connecting the target signal in parallel with the signal with the same name and type in the first component 1 (the second component 2 is similar and will not be described in detail). If there are other pins between the pin corresponding to the target signal and the pin of the signal with the same name and type in the first component 1 (the two may also be adjacent), the pin corresponding to the target signal can be connected to the pin of the signal with the same name and type through a line; if the pin corresponding to the target signal is adjacent to the pin of the signal with the same name and type in the first component 1, the pin corresponding to the target signal can be connected to the solder pad corresponding to the pin of the signal with the same name and type as a whole. The user can make a choice according to the actual situation.

[0108] As mentioned above, the impedance value of the wiring corresponding to a set of signals is inversely proportional to the cross-sectional area of ​​the wiring pattern 200 at that location. In one embodiment of the wiring method of the display panel of the present invention, the step of adjusting the signal correspondence relationship between the first component 1 and the second component 2 also includes:

[0109] Adjust the thickness of the electrical connection material between the target signals of the first component 1 and the second component 2, and / or adjust the electrical connection range of the target signal on the corresponding pad. In this way, by adjusting (increasing) the thickness of the electrical connection material between the target signals of the first component 1 and the second component 2, increasing the cross-sectional area of ​​the wiring pattern 200 at this location, the impedance value of the wiring corresponding to the group of signals can be reduced.

[0110] In one embodiment of the wiring method of the display panel of the present invention, the step of adjusting the signal correspondence between the first component 1 and the second component 2 further includes:

[0111] The number of spacing pins between the target signal and the adjacent signal of the first component 1 is adjusted according to the voltage of the signal, and / or the number of spacing pins between the target signal and the adjacent signal of the second component 2 is adjusted according to the voltage of the signal. In one embodiment, in the second component 2, when the voltage of one of the target signals is higher, in order to reduce its influence on the transmission of the adjacent signal, the distance between the target signal and the adjacent signal can also be increased, that is, the number of spacing pins between the target signal and the adjacent signal is increased. In a further implementation scheme, when the voltage of the target signal does not affect the transmission of the adjacent signal, the number of spacing pins between the target signal and the adjacent signal can be reduced, so that the total wiring length of the second component 2 can be reduced, and the wiring space requirements between the first component 1 and the second component 2 can be met.

[0112] For a better explanation of the present invention, please refer to Figure 6 , Figure 6A block diagram of a wiring device 300 for a display panel in an embodiment of the present invention is shown. The present invention also discloses a wiring device 300 for a display panel. The display panel has an adjacent display area and a peripheral area.

When designing the wiring pattern 200, the signal correspondence between the first component 1 and the second component 2 can be included in the specification document. The wiring device 300 for a display panel includes: a wiring pattern generation module 310 and a specification compliance recognition module 320. The wiring pattern generation module 310 further includes a signal correspondence detection module 311, a wiring drawing logic definition module 312, and an automatic drawing module 313. The wiring pattern generation module 310 is used to automatically generate a wiring pattern 200 for electrically connecting the first component 1 and the second component 2 according to the specification document. The signal correspondence detection module 311 is used to automatically detect whether there is an abnormality in the signal correspondence between the first component 1 and the second component 2 in the specification document; the wiring drawing logic definition module 312 is used to define the wiring drawing logic according to the signal correspondence between the first component 1 and the second component 2 and generate a wiring drawing instruction; the automatic drawing module 313 is used to generate a wiring pattern 200 according to the wiring drawing instruction. The specification compliance identification module 320 is used to identify whether the wiring pattern 200 meets the first specification requirement of the specification document. Among them, the wiring pattern generation module 310 is also used to adjust the signal correspondence between the first component 1 and the second component 2 when the wiring pattern 200 does not meet the first specification requirement, and then automatically regenerate the wiring pattern 200 for electrically connecting the first component 1 and the second component 2 according to the specification document until the first specification requirement is met. In one embodiment, the specification compliance identification module 320 is independent of the wiring pattern generation module 310. In another embodiment, the specification compliance identification module 320 can also be set in the wiring pattern generation block 310, for example, in the signal correspondence detection module 311, but it is not limited thereto.

[0113] In one embodiment of the wiring device 300 of the display panel of the present invention, the signal correspondence detection module 311 is used to detect whether the total number of signals of the first component 1 and the second component 2 corresponds, and detect whether the parameter correspondence between the signals of the first component 1 and the second component 2 is correct. In this embodiment, before automatically generating the wiring pattern 200 in the wiring drawing software according to the signal correspondence between the first component 1 and the second component 2, it is detected whether there is an abnormality in the signal correspondence between the first component 1 and the second component 2, so that the error in the signal correspondence between the first component 1 and the second component 2 in the specification document can be discovered in advance, avoiding tracing back the error after generating the wiring pattern 200, and improving the efficiency of wiring design.

[0114] In one embodiment of the wiring device 300 of the display panel of the present invention, the signals of the first component 1 and the second component 2 with the same name and type are a group of corresponding signals 100, the signal corresponding to the first pin of the first component 1 in the group of corresponding signals 100 is recorded as the first signal 110, and the signal corresponding to the second pin of the second component 2 is recorded as the second signal 120, and the signal correspondence detection module 311 can be used to detect whether the name and / or type of the first signal 110 and the second signal 120 in each group of corresponding signals 100 are the same, detect whether the corresponding number of the first signal 110 in each group of corresponding signals 100 corresponds to the number of the second signal 120, and / or whether the corresponding number of the second signal 120 in each group of corresponding signals 100 corresponds to the number of the first signal 110.

[0115] In one embodiment of the wiring device 300 of the display panel of the present invention, the wiring drawing logic definition module 312 is used to determine the signal position starting point of the first component 1 and the second component 2 according to the wiring drawing origin; and according to the number and size of the pins corresponding to each signal in the first component 1 and the second component 2, according to the signal correspondence between the first component 1 and the second component 2, determine the drawing position and width of multiple first solder pads 11 corresponding to the first component 1 and multiple second solder pads 12 corresponding to the second component 2 according to the signal numbering order; and determine the connection relationship between each first solder pad 11 and each second solder pad 12 according to the signal correspondence between the first component 1 and the second component 2.

[0116] In one embodiment of the wiring device 300 of the display panel of the present invention, the specification compliance identification module 320 is used to detect whether the wiring pattern 200 meets the space requirements between the first component 1 and the second component 2 and / or calculate whether the impedance value of the wiring corresponding to each pin of the first component 1 and the second component 2 meets the impedance value requirements in the specification document.

[0117] In one embodiment of the wiring device 300 of the display panel of the present invention, when the wiring pattern 200 does not meet the first specification requirements, the signals corresponding to the pin numbers on the first component 1 and the second component 2 that are identified as not meeting the first specification requirements are recorded as target signals, and the wiring pattern generation module 310 is also used to connect the target signal located in the first component 1 in parallel with the signal with the same name and type of the first component 1, and / or connect the target signal located in the second component 2 in parallel with the signal with the same name and type of the second component 2. As with the calculation method of the impedance value of the wiring corresponding to a group of corresponding signals 100 introduced above, connecting the target signal in parallel with the signal with the same name and type will increase the width of the closed figure formed by the connection line of the first signal 110 and the second signal 120 in the group of signals, thereby reducing the impedance value of the group of signals.

[0118] In one embodiment of the wiring device 300 of the display panel of the present invention, the wiring pattern generation module 310 is also used to adjust the thickness of the electrical connection material between the target signal of the first component 1 and the second component 2, and / or adjust the electrical connection range of the target signal on the corresponding pad. As mentioned above, the impedance value of the wiring corresponding to a group of corresponding signals 100 is inversely proportional to the cross-sectional area of ​​the wiring. Adjusting (increasing) the thickness of the electrical connection material between the target signal of the first component 1 and the second component 2 can reduce the impedance value of the group of signals. In one embodiment, adjusting the electrical connection range of the target signal on the corresponding pad can also increase the width of the closed figure composed of the connection lines of the first signal 110 and the second signal 120 in a group of corresponding signals 100, thereby reducing the impedance value of the wiring corresponding to the group of signals.

[0119] In one embodiment of the wiring device 300 of the display panel of the present invention, the wiring pattern generation module 310 is also used to adjust the number of spacing pins between the target signal and the adjacent signal of the first component 1 according to the voltage of the signal, and / or adjust the number of spacing pins between the target signal and the adjacent signal of the second component 2 according to the voltage of the signal. As mentioned above, in one embodiment, in the second component 2, when the voltage of one of the target signals is higher, in order to reduce its influence on the transmission of the adjacent signal, the distance between the target signal and the adjacent signal can also be increased, that is, the number of spacing pins between the target signal and the adjacent signal is increased. In a further implementation scheme, when the voltage of the target signal does not affect the transmission of the adjacent signal, the number of spacing pins between the target signal and the adjacent signal can be reduced, so that the total wiring length of the second component 2 can be reduced, and the wiring space requirements between the first component 1 and the second component 2 can be met.

[0120] The wiring method and wiring device of the display panel disclosed in the present invention automatically generate a wiring pattern between the signals of a first component and a second component according to a specification document. When the wiring pattern does not meet the requirements of the first specification, the signal correspondence between the first component and the second component is adjusted, and the wiring pattern between the first component and the second component is automatically regenerated until the requirements of the first specification are met, thereby solving the problem of low efficiency and easy errors in manual drawing during display panel design, and greatly speeding up the speed of wiring design in the display panel.
