[0071] Figure 7 Partial schematic diagram of the display device provided in the embodiments of this disclosure Figure 6 . Detailed Implementation

[0072] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Note that the implementation methods can be carried out in many different forms. Those skilled in the art will readily understand that the methods and content can be transformed into various forms without departing from the spirit and scope of this disclosure. Therefore, this disclosure should not be construed as limited to the content described in the following embodiments. Without conflict, the embodiments and features in the embodiments of this disclosure can be arbitrarily combined with each other. To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of some known functions and components have been omitted. The accompanying drawings of the embodiments of this disclosure only relate to the structures involved in the embodiments of this disclosure; other structures can be referred to in general design.

[0073] In the accompanying drawings, the size of the constituent elements, the thickness of the layers, or the area are sometimes exaggerated for clarity. Therefore, one aspect of this disclosure is not necessarily limited to these dimensions, and the shapes and sizes of the components in the drawings do not reflect true proportions. Furthermore, the drawings schematically illustrate ideal examples, and one aspect of this disclosure is not limited to the shapes or values ​​shown in the drawings.

[0074] The ordinal numbers “first,” “second,” and “third” used in this specification are used to avoid confusion among the constituent elements, not to limit their quantity.

[0075] In this specification, for convenience, terms such as "middle," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to indicate orientation or positional relationships in conjunction with the accompanying drawings. This is solely for the purpose of facilitating the description and simplification, and does not imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this disclosure. The positional relationships of the constituent elements may be appropriately varied depending on the orientation of each constituent element being described. Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0076] In this specification, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection, an indirect connection via an intermediate component, or a connection within two components. Those skilled in the art will understand the specific meaning of these terms in this disclosure based on the specific circumstances.

[0077] In this specification, a transistor is a device that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between the drain electrode (drain electrode terminal, drain region, or drain electrode) and the source electrode (source electrode terminal, source region, or source electrode), and current can flow through the drain electrode, the channel region, and the source electrode. Note that in this specification, the channel region refers to the region through which current primarily flows.

[0078] In this specification, the first electrode can be the drain electrode and the second electrode can be the source electrode, or vice versa. In cases where transistors with opposite polarities are used or the current direction changes during circuit operation, the functions of the "source electrode" and "drain electrode" may sometimes be interchanged. Therefore, in this specification, the "source electrode" and "drain electrode" can be interchanged.

[0079] In this specification, "electrical connection" includes the situation where components are connected together by elements that have a certain electrical function. There are no particular limitations on what constitutes an "electrical function," as long as it allows for the transmission and reception of electrical signals between the connected components. Examples of "electrical functions" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements with various functions.

[0080] In this specification, "parallel" refers to the state where the angle formed by two straight lines is greater than or equal to -10° and less than 10°, and therefore also includes the state where the angle is greater than or equal to -5° and less than 5°. Similarly, "perpendicular" refers to the state where the angle formed by two straight lines is greater than or equal to 80° and less than 100°, and therefore also includes the state where the angle is greater than or equal to 85° and less than 95°.

[0081] In this specification, the terms "film" and "layer" may be interchanged. For example, "conductive layer" may sometimes be replaced with "conductive film." Similarly, "insulating film" may sometimes be replaced with "insulating layer."

[0082] In this specification, the term "same-layer arrangement" refers to a structure formed by patterning two (or more) structures through the same patterning process, and their materials may be the same or different. For example, the precursors forming multiple structures in a same-layer arrangement may be made of the same material, while the final materials may be the same or different.

[0083] In this specification, triangles, rectangles, trapezoids, pentagons, or hexagons are not strictly defined; they can be approximate triangles, rectangles, trapezoids, pentagons, or hexagons. Small deformations due to tolerances are possible, as are chamfers, curved edges, and other variations.

[0084] In this disclosure, “about” means a value that is not strictly limited and allows for process and measurement errors.

[0085] Display devices typically connect the PCB (printed circuit board) and the display screen via COF (chip-on-film), which contains drivers. Because the structure of the COF with drivers is complex, the manufacturing yield of the COF is low, and the possibility of defects during assembly with the drivers is very high. When there are manufacturing defects in the COF or poor assembly with the drivers, the COF becomes unusable and must be discarded, resulting in a waste of resources.

Furthermore, the source driver 10 is electrically connected to the sub-pixel via the data signal line DL.

This disclosure, by providing a repair module, can provide signals to the data signal lines connected to the broken data signal transmission lines when there are manufacturing defects in the COF or poor assembly with the driver, ensuring the normal display of the display device and avoiding waste.

[0102] In an exemplary embodiment, when the display device includes a flip-chip film 200, a source driver is disposed on the flip-chip film.

[0103] In an exemplary embodiment, the repair module is disposed in at least one of the display panel and the flip film, and the data signal transmission line 13 is disposed on the display panel 100 and the flip film 200.

[0104] In an exemplary implementation, such as Figures 2 to 5 As shown, the source driver may include: a data processing circuit 11 and multiple signal output circuits 12. The signal output circuit 12 may include: a shift register 121, a data latch circuit 122, a level conversion circuit 123, a digital-to-analog conversion circuit 124, and an output buffer circuit 125.

[0105] In an exemplary embodiment, the source driver may further include: a plurality of interface circuits electrically connected to the data processing circuits and configured to convert received signals from the timing controller 20 into image data and output them to the data processor.

[0106] In an exemplary embodiment, multiple interface circuits 101 may have the same structure. The image data received by the multiple interface circuits can be adjusted according to the position of the sub-pixels in the display panel, which is not limited herein. Furthermore, this disclosure does not limit the interface type of the interface circuits, and those skilled in the art can set it according to actual conditions. For example, the interface circuit may include a Mini Low Voltage Differential Signaling (Mini-LVDS) interface or a Point-to-Point (P2P) interface.

[0107] In an exemplary embodiment, the data processing circuit 11 can be configured to preprocess the received image data. Exemplarily, preprocessing includes performing data reversal processing, serial-to-parallel conversion processing, and implementing a data exchange (SWAP) function on the image data. Since the data processing circuit processes digital signals, it improves the speed and accuracy of signal processing compared to processing analog signals before the input of the output buffer circuit. Furthermore, placing the data processing circuit in a low-voltage region allows for a reduction in the size of the source driver 10 compared to placing it in a high-voltage region.

[0108] In an exemplary embodiment, the data processing circuit 11 is further configured to provide a shift register signal to the shift register, wherein the shift register signal may include an initial signal or a reset signal.

[0109] In an exemplary embodiment, shift register 121, electrically connected to data processing circuit 11, is configured to sample and output preprocessed image data to generate a first data signal.

[0110] In an exemplary embodiment, both the preprocessed image data and the first data signal are digital signals.

[0111] In an exemplary embodiment, the shift register includes at least one shift register unit. When the shift register includes multiple shift register units, the multiple shift register units located in the same shift register are cascaded together.

[0112] In an exemplary embodiment, the data latch circuit 122, electrically connected to the shift register 121, is configured to latch the first data signal and output the second data signal.

[0113] In the exemplary embodiment, there is a one-to-one correspondence between the data latch circuits and the shift registers. That is, the number of data latch circuits and shift registers is the same. The output of the data latch circuit is a parallel output. It can be understood that since the shift register units in the shift register sequentially sample and output the digitized image data, that is, the output of the shift register is a serial output, the data latch circuit sequentially latches the first data signal output by the corresponding shift register.

[0114] In an exemplary embodiment, each data latch circuit includes multiple data latch units, and the number of data latch units in the data latch circuit is positively correlated with the shift register corresponding to the data latch circuit.

The repair output circuit generates a data signal to be provided to the data signal line connected to the broken data signal transmission line based on the preprocessed repair image data.
