[0041] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the sentence "comprise..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0043] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the display panel and display device of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0044] Optical fingerprint technology can avoid interference from ambient light to the greatest extent during the recognition process. In conventional optical fingerprint technology, the optical fingerprint recognition unit and the circuit that controls the optical fingerprint recognition unit are usually set on the backlight side of the display panel, which is called under-screen optical fingerprint technology. However, with the emergence of low-temperature polysilicon oxide (LTPO) circuit design, further improvement of pixel density, and further integration of new technologies such as depolarizer technology (Color filter On Encapsulation, COE) with display panels, the transmittance of the display panel itself is getting lower and lower, and the under-screen optical fingerprint technology is gradually unable to meet the demand.

[0045] To this end, technicians skilled in the art have proposed a new design scheme, namely, in-screen optical fingerprint technology, in which the fingerprint recognition unit and functional elements such as the light-emitting unit of the display panel are arranged on the same side of the light-emitting side of the display panel, wherein the circuit controlling the fingerprint recognition unit and the pixel display circuit are integrated together, which can further break through the limitation of the screen transmittance.

[0046] For a circuit arrangement scheme in which an additional circuit for controlling a fingerprint recognition unit is added to the original pixel display circuit, please refer to Figure 1, there is a problem of crowded circuit layout. The data signal line (data) of the pixel display circuit and the read signal line (readout) of the circuit controlling the fingerprint recognition unit are both vertical metal lines and are arranged on the same layer. The distance between the two is relatively close, resulting in a large parasitic capacitance between them. At the same time, the voltage of the data line is constantly jumping when writing data line by line in the pixel display circuit, thereby affecting the voltage of the readout line to change continuously, resulting in abnormal fingerprint recognition.

[0047] Based on considerations and technical needs for solving the above-mentioned problems, the present application proposes a display panel 100 and a display device.

[0048] In order to better understand this application, Figures 2 to 4 , Figures 5 and 6 The display panel 100 according to the embodiment of the present application is described in detail.

[0049] See also Figure 2 and Figure 3 In a first aspect, an embodiment of the present application provides a display panel 100 including a display area 10 , the display area 10 including a first functional area 11 , and the display panel 100 further includes a functional component 20 , a driving component 30 and a signal line 40 .

[0050] The functional component 20 includes a light emitting unit 21 and a functional unit 22 . The light emitting unit 21 includes a first light emitting unit 211 located in the first functional area 11 . The functional unit 22 is located in the first functional area 11 .

[0051] The driving component 30 includes a functional circuit 33 and a first display circuit 31 . The functional circuit 33 drives the functional unit 22 , and the first display circuit 31 drives the first light-emitting unit 211 .

At least one column of light emitting units 21 is disposed between any data signal line 41 and read signal line 42 .

[0054] Compared with the prior art, the display panel 100 provided in the embodiment of the present application has at least the following beneficial technical effects:

[0055] By arranging the data signal line 41 connected to the first display circuit 31 for driving the first light-emitting unit 211 and the read signal line 42 connected to the functional circuit 33 for driving the functional unit 22 between two columns of light-emitting units 21, and at least one column of light-emitting units 21 is arranged between any data signal line 41 and the read signal line 42, the data signal line 41 and the read signal line 42 can be separated by the light-emitting units 21, thereby increasing the spacing between the data signal line 41 and the read signal line 42, reducing the parasitic capacitance between the data signal line 41 and the read signal line 42, and preventing crosstalk between the data signal line 41 and the read signal line 42, thereby ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0056] Exemplarily, the first functional area 11 of the display area 10, in the embodiment of the present application, can be set as a fingerprint recognition area.

[0057] In the embodiment where the first functional area 11 is set as a fingerprint recognition area, the first functional area 11 is usually set in the middle of the display area 10 and closer to the lower frame of the display panel 100 to facilitate user finger touch and fingerprint verification operations.

[0058] Optionally, the first functional area 11 can also be set to other specific areas that require additional functional units 22 to be added between the light-emitting units 21 in the display panel 100 to achieve additional functions, including but not limited to under-screen camera hole areas, special sensor hole areas, and electromagnetic touch (Electronic Magnetic Resonance, EMR) areas, etc., which are not limited to the embodiments of the present application.

[0059] For example, in an embodiment where the first functional area 11 is set as a fingerprint recognition area, the functional unit 22 can be set as a fingerprint recognition unit. The functional unit 22 and the light-emitting unit 21 having a display function in the display panel 100 can be set in the same layer to further break through the limit of the screen transmittance and realize the in-screen fingerprint technology.

[0060] Optionally, the fingerprint recognition unit can also be set on the backlight side of the display panel 100, close to the array substrate of the display panel 100 and away from the light-emitting unit 21, maintaining the traditional under-screen fingerprint technology.

[0061] Optionally, the functional unit 22 can also be configured as an element to implement other functions of the display panel 100 in addition to the light-emitting and display functions, including but not limited to an under-screen camera array, a sensor array, and an EMR unit, etc., which is not limited in the embodiments of the present application.

[0062] Exemplarily, the functional circuit 33 is a circuit for driving the functional unit 22. In the embodiment where the first functional area 11 is set as a fingerprint identification area, the functional circuit 33 can also be set as a fingerprint circuit.

[0063] The first display circuit 31 driving the first light-emitting unit 211 in the display panel 100 can be set to a 2T1C circuit, a 4T1C circuit, a 7T1C circuit, etc. The first display circuit 31 includes at least one driver transistor (Driver Thin Film Transistor, DTFT), a switch transistor (Switch Thin Film Transistor, STFT) and a storage capacitor (Capacitance, C), wherein the DTFT can be set to a hole-type semiconductor transistor (Positive TFT, P-type TFT), and the STFT can be set to an electron-type semiconductor transistor (Negative TFT, N-type TFT), P-type TFT, Indium Gallium Zinc Oxide TFT (Indium Gallium Zinc Oxide TFT, IGZO TFT), N-type low-temperature polysilicon TFT (Low Temperature Poly-Silicon TFT, LTPS TFT) and other types.

[0064] The fingerprint circuit can be set as a 3T advanced photo system circuit (APS), and the fingerprint circuit can include three N-type TFTs, such as IGZO or N-type LTPS TFTs. The fingerprint circuit can also be set as a 4T APS circuit or a 5T APS circuit.

[0065] Optionally, the functional circuit 33 can also be set to drive the driving circuit of other functional units 22, including but not limited to the under-screen camera array driving circuit, the sensor array driving circuit and the EMR unit driving circuit, etc., which is not limited to the embodiments of the present application.

[0066] Exemplarily, the plurality of light emitting units 21 are arranged in an array along the row direction X and the column direction Y. The arrangement of the light emitting units 21 is used to specify the direction only for the convenience of explanation. Those skilled in the art may also specify a first direction and a second direction on the plane of the display panel 100 for explanation, as long as the arrangement of the signal line 40 and the driving component 30 can be clearly explained.

[0067] Exemplarily, among the signal lines 40 connecting the driving components 30, the signal lines 40 in the same direction are usually arranged in the same layer. The data signal line 41 is a signal line 40 arranged along the column direction Y of the light emitting unit 21, and can connect multiple first display circuits 31 arranged along the column direction Y of the light emitting unit 21. At the same time, the read signal line 42 is also a signal line 40 arranged along the column direction Y of the light emitting unit 21, and can connect multiple functional units 22 arranged along the column direction Y of the light emitting unit 21.

[0068] The data signal line 41 and the read signal line 42 are both signal lines 40 arranged along the column direction Y of the light emitting units 21 .

[0069] Exemplarily, the data signal line 41 and the read signal line 42 are arranged in the same layer. In the embodiment of the present application, at least one column of light-emitting units 21 is arranged between any data signal line 41 and the read signal line 42, and the data signal line 41 and the read signal line 42 are spaced apart by the light-emitting units 21, so that even if the functional circuit 33 is added to the first functional area 11, making the circuit layout in the first functional area 11 more crowded, the normal operation of the first display circuit 31 and the functional circuit 33 can be ensured.

[0070] Exemplarily, the data signal line 41 and the read signal line 42 are both disposed between two adjacent columns of light emitting units 21 .

[0071] In some optional embodiments, the two columns of light emitting units 21 arranged on both sides of the data signal line 41 are different from the two columns of light emitting units 21 arranged on both sides of the read signal line 42 .

[0072] In these optional embodiments, there are at least two columns of light-emitting units 21 between the data signal line 41 and the read signal line 42, and there is at least a spacing of the width of two columns of light-emitting units 21 between the data signal line 41 and the read signal line 42, which can ensure the normal operation of the first display circuit 31 and the functional circuit 33.

[0073] In some other optional embodiments, one of the two columns of light emitting units 21 arranged on both sides of the data signal line 41 and the two columns of light emitting units 21 arranged on both sides of the read signal line 42 is the same.

[0074] In these optional embodiments, there is at least one column of light-emitting units 21 between the data signal line 41 and the read signal line 42, and at least one column of the light-emitting units 21 is arranged between the data signal line 41 and the read signal line 42. Therefore, there is at least a spacing of the width of one column of light-emitting units 21 between the data signal line 41 and the read signal line 42, which can also ensure the normal operation of the first display circuit 31 and the functional circuit 33.

[0075] In some embodiments, see Figure 2 and Figure 3 The display area 10 also includes a second functional area 12 at least partially surrounding the first functional area 11 , at least part of the first display circuit 31 and the data signal line 41 are arranged in the second functional area 12 , and the read signal line 42 is arranged in the first functional area 11 .

[0076] In the display panel 100 provided in the embodiment of the present application, the display area 10 also includes a second functional area 12. By directly transferring at least part of the first display circuit 31 and the data signal line 41 to the second functional area 12, and the read signal line 42 is also set in the first functional area 11, the distance between the two is further increased, thereby ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0077] The second functional area 12 is the other area of ​​the display area 10 except the first functional area 11. While the second functional area 12 is arranged around the first functional area 11, it can only include the light-emitting unit 21 that realizes the light-emitting and display functions and the display circuit structure that drives the corresponding light-emitting unit 21. The first display circuit 31 is directly transferred to the second functional area 12, that is, the data signal line 41 connecting the first display circuit 31 and the read signal line 42 connecting the functional circuit 33 can be increased in distance, thereby ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0078] Optionally, at least part of the first display circuit 31 is transferred to the second functional area 12, and the spatial position where part of the first display circuit 31 was originally set in the first functional area 11 is filled with a virtual circuit pattern, so as to further ensure the display uniformity of the display panel 100 and prevent the display unevenness when the display panel 100 is turned off due to the lack of circuit pattern distribution.

[0079] In some embodiments, the ratio of the number of the first light-emitting units 211 to the number of the functional units 22 in the functional component 20 is greater than or equal to 1:1, so as to minimize the number of the functional units 22 and the space they occupy.

[0080] In some embodiments, see Figure 2 and Figure 3 The ratio of the number of the first light-emitting units 211 to the number of the functional units 22 in the functional component 20 is 2:1. The two first light-emitting units 211 are arranged side by side along the row direction X, and the functional unit 22 and the two first light-emitting units 211 are arranged side by side along the column direction Y.

[0081] The display panel 100 provided in the embodiment of the present application proposes an arrangement method and quantity ratio of the first light-emitting unit 211 and the functional unit 22 in the functional component 20 in the first functional area 11, which can minimize the number and space occupied by the functional units 22 while realizing other additional functions.

[0082] The first light-emitting units 211 and the functional units 22 in the functional component 20 are arranged in such a manner and in such a quantity ratio that the signal line 40 connecting one functional component 20 includes two data signal lines 41 connecting two first light-emitting units 211 and one read signal line 42 connecting the functional unit 22.

[0083] In some embodiments, see Figure 2 and Figure 3 The first display circuit 31 corresponding to at least one first light-emitting unit 211 in each functional component 20 and the data signal line 41 connected to the first display circuit 31 are located in the second functional area 12 .

[0084] The display panel 100 provided in the embodiment of the present application, by adopting the arrangement method and quantity ratio of the first light-emitting unit 211 and the functional unit 22 in the functional component 20 in the above-mentioned embodiment, arranges the first display circuit 31 corresponding to at least one first light-emitting unit 211 and the data signal line 41 connecting the first display circuit 31 in the second functional area 12, thereby being able to at least increase the distance between most of the data signal lines 41 and the reading signal lines 42, thereby ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0085] Exemplarily, when a display panel 100 having the arrangement and quantity ratio of the first light-emitting unit 211 and the functional unit 22 within the functional component 20 in the above-mentioned embodiment is adopted, the first display circuit 31 arranged in the second functional area 12 and the data signal line 41 connected thereto can be set to be the first display circuit 31 corresponding to the first light-emitting unit 211 that is closer to the functional unit 22 and the reading signal line 42 connected thereto, while the first display circuit 31 corresponding to the first light-emitting unit 211 that is farther away from the functional unit 22 and the data signal line 41 connected thereto are retained.

[0086] The first display circuit 31 arranged in the second functional area 12 can be set to be the first display circuit 31 corresponding to the first light-emitting unit 211 closer to the functional unit 22 in the display panel 100 adopting the arrangement method and quantity ratio of the first light-emitting unit 211 and the functional unit 22 in the functional component 20 in the above-mentioned embodiment, while retaining the first display circuit 31 corresponding to the first light-emitting unit 211 farther from the functional unit 22.

[0087] The data signal line 41 connected to the part of the first display circuit 31 retained in the first functional area 11 and the read signal line 42 connected to the functional unit 22 are farther away from each other in the setting method of the functional component 20 in the above embodiment, that is, the data signal line 41 and the read signal line 42 are arranged between the two columns of first light-emitting units 211 in the first functional area 11 and the two are separated by the first light-emitting units 211, while the data signal line 41 connected to the other part of the first display circuit 31 arranged in the second functional area 12 is farther away from the read signal line 42, thereby ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0088] Optionally, the first display circuit 31 arranged in the second functional area 12 can also be set to all two first display circuits 31 in the setting method of the functional component 20 in the above embodiment, and all the first display circuits 31 and the data signal lines 41 are transferred to the second functional area 12, further ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0089] Optionally, in an implementation of transferring part of the first display circuit 31 to the second functional area 12, the display panel 100 provided in the embodiment of the present application can also be configured to fill the spatial position of the first display circuit 31 transferred to the second functional area 12 with a virtual circuit pattern, so as to further ensure the display uniformity of the display panel 100 and prevent the display unevenness problem when the display panel 100 is turned off due to the lack of circuit pattern distribution.

[0090] In some optional embodiments, the data signal lines 41 and the read signal lines 42 in the first functional area 11 are alternately arranged along the row direction X.

[0091] The display panel 100 provided in the embodiment of the present application can further increase the spacing between the data signal lines 41 of the part of the first display circuit 31 and the reading signal lines 42 of the functional circuit 33 retained in the first functional area 11, under the premise that at least one column of first light-emitting units 211 is arranged between any data signal line 41 and the reading signal line 42 in the first functional area 11, so that the spacing distribution between the data signal lines 41 and the reading signal lines 42 in the entire first functional area 11 is more uniform, further reducing the parasitic capacitance between the signal lines 40, so that the signal lines 40 do not crosstalk with each other, and further ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0092] In some embodiments, see Figure 2 and Figure 4 , the plurality of first display circuits 31 are all located in the second functional area 12 .

[0093] The display panel 100 provided in the embodiment of the present application can transfer all the first display circuits 31 and data signal lines 41 originally arranged in the first functional area 11 to the second functional area 12 , further ensuring the normal operation of the first display circuits 31 and the functional circuits 33 .

[0094] Optionally, the space where the first display circuit 31 is originally arranged in the first functional area 11 is filled with a dummy circuit pattern to further ensure the uniformity of the display panel 100 .

[0095] In some optional embodiments, see Figure 2 and Figure 4 The light-emitting unit 21 includes a second light-emitting unit 212 arranged in the second functional area 12, the read signal line 42 is arranged between two columns of first light-emitting units 211, and the data signal line 41 is arranged between two columns of second light-emitting units 212, or the data signal line 41 is located between adjacent first light-emitting units 211 and second light-emitting units 212.

[0096] In the display panel 100 provided in the embodiment of the present application, the read signal line 42 and the data signal line 41 are respectively arranged between the first light-emitting units 211 in the first functional area 11 and between the second light-emitting units 212 in the second functional area 12, thereby further increasing the spacing between the signal lines 40 and further ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0097] Optionally, the data signal line 41 may also be arranged at the junction of the first functional area 11 and the second functional area 12, close to the side of the second functional area 12, that is, the two columns of light-emitting units 21 on both sides of the data signal line 41 may be set as one column of first light-emitting units 211 and the other column of second light-emitting units 212. Although the data signal line 41 arranged between two adjacent columns of second light-emitting units 212 is closer to the reading signal line 42 arranged between the first light-emitting units 211, the normal operation of the first display circuit 31 and the functional circuit 33 can still be guaranteed.

[0098] In some embodiments, see Figure 2 and Figure 4 The display circuit also includes a second display circuit 32 disposed in the second functional area 12 , the second display circuit 32 drives the second light-emitting unit 212 , and the first display circuit 31 of the second functional area 12 is located between two adjacent second display circuits 32 .

[0099] The display panel 100 provided in the embodiment of the present application arranges the first display circuit 31 transferred from the first functional area 11 to the second functional area 12 between adjacent second display circuits 32, and leaves some space between the second display circuits 32 to accommodate the first display circuit 31 transferred from the first functional area 11 to the second functional area 12.

[0100] In some optional embodiments, multiple second display circuits 32 are arranged in the second functional area 12 to form multiple second display circuit rows 35, and the same second display circuit row 35 is formed by repeatedly arranging second circuit repetition units 34 along the row direction X, and the first display circuit 31 of the second functional area 12 is set in the second circuit repetition unit 34.

[0101] The display panel 100 provided in the embodiment of the present application arranges the first display circuit 31 in the second circuit repetition unit 34 in the same second display circuit row 35, further reducing the impact on the second display circuit 32 originally arranged in the second functional area 12, and only needs to redesign the circuit layout in the second circuit repetition unit 34 to make at least part of the space to accommodate the first display circuit 31, and does not need to redesign the circuit layout of all the second display circuits 32 in the second functional area 12, thereby reducing design and production costs.

[0102] In the second functional area 12, the second light-emitting units 212 are arranged and combined in a certain order to form a specific pixel structure to achieve a better light-emitting effect. Optionally, a common light-emitting unit 21 combination includes a red sub-pixel light-emitting unit (R), a green sub-pixel light-emitting unit (G), a blue sub-pixel light-emitting unit (B) and a green sub-pixel light-emitting unit (G), and at the same time, the second display circuit 32 corresponding to the second light-emitting unit 212 in the second functional area 12 is also formed in the second circuit repeating unit 34 in the same row, and the arrangement of the circuit and the arrangement of the pixels are adapted to set the first display circuit 31 between the second display circuit 32 for driving the G sub-pixel and the second display circuit 32 for driving the B sub-pixel, so that the distance between the adjusted second display circuit 32 and the second light-emitting unit 212 driven by it is closer, so that the same circuit layout design adjustment is performed in each second circuit repeating unit 34.

[0103] Optionally, since the layout of the second light-emitting unit 212 is unchanged, and the second display circuit 32 needs to be redesigned to make room for the first display circuit 31, there is a certain deviation and misalignment between the second display circuit 32 and the second light-emitting unit 212 in the orthographic projection direction of the display panel 100. When the deviation and misalignment are small, the electrodes of the second display circuit 32 and the second light-emitting unit 212 can still be connected through existing wiring. When the deviation and misalignment are large, additional wiring can also be set between the electrodes of the second display circuit 32 and the second light-emitting unit 212 for connection, so as to ensure the connection effect between the electrodes of the second display circuit 32 and the second light-emitting unit 212.

[0104] In some optional embodiments, a plurality of first display circuits 31 driving the first light emitting units 211 in the same row are located in the same second display circuit row 35 .

[0105] The display panel 100 provided in the embodiment of the present application can directly transfer the entire row of first display circuits 31 to the entire row of second display circuits 35 , further reducing the design and production costs.

[0106] In some optional embodiments, the plurality of first display circuits 31 driving the first light emitting units 211 in the same row are located in the same second display circuit row 35 driving the second light emitting units 212 arranged in the same row as the first light emitting units 211 .

[0107] The display panel 100 provided in the embodiment of the present application can facilitate the signal lines 40 arranged along the row direction X, such as the scanning signal line (Scan), by directly transferring the first display circuit 31 driving the first light-emitting unit 211 in the same row to the second display circuit row 35 corresponding to the second light-emitting unit 212 arranged in the same row as the first light-emitting unit 211, so as to still drive the first display circuit 31 and the second display circuit 32 in the same row row by row, without adjusting the existing circuit layout design or adding new signal lines 40, thereby further reducing the design and production costs.

[0108] In some optional embodiments, the arrangement order of the plurality of first light-emitting units 211 in the same row is the same as the arrangement order of the plurality of first display circuits 31 driving the plurality of first light-emitting units 211 in the same row.

[0109] The display panel 100 provided in the embodiment of the present application does not need to adjust the arrangement sequence of the first display circuits 31 , and can be directly transferred to the second functional area 12 according to the arrangement sequence set in the first functional area 11 , thereby further reducing design and production costs.

[0110] The first light-emitting unit 211 driven by the first display circuit 31 can also be arranged in a certain order to form a specific pixel structure to achieve a better light-emitting effect. Optionally, the first light-emitting unit 211 is arranged in an RGBG arrangement, and the first display circuit 31 is also arranged in an arrangement of the corresponding RGBG sub-pixel light-emitting unit. When the first display circuit 31 is transferred to the second functional area 12, there is no need to adjust the order of the first display circuit 31, further reducing the design and production costs.

[0111] In some embodiments, see Figure 2 The first display circuit 31 located in the second functional area 12 is connected to the corresponding first light-emitting unit 211 located in the first functional area 11 through the metal wiring 50 .

[0112] The display panel 100 provided in the embodiment of the present application connects the first display circuit 31 and the first light-emitting unit 211 through the metal wiring 50 , thereby ensuring the normal operation of the first display circuit 31 .

[0113] The electrodes of the first display circuit 31 and the first light emitting unit 211 are located in the second functional area 12 and the first functional area 11 respectively, and the distance between them is relatively far, so it is necessary to add additional metal wiring 50 to connect the first display circuit 31 and the corresponding electrode of the first light emitting unit 211 .

[0114] In some embodiments, please refer to Figure 5 and Figure 6 The first display circuit 31 is disposed in the first functional area 11 , and at least one column of first light-emitting units 211 is disposed between any data signal line 41 and any read signal line 42 .

[0115] The display panel 100 provided in the embodiment of the present application sets both the data signal line 41 and the read signal line 42 in the first functional area 11 , and there is no need to transfer the first display circuit 31 out of the first functional area 11 , which can further reduce the design and production costs.

[0116] In some optional embodiments, a plurality of read signal lines 42 are disposed between the same two columns of first light emitting units 211 .

[0117] The display panel 100 provided in the embodiment of the present application exchanges the positions of the read signal line 42 and the data signal line 41 in the first functional area 11, and sets the two read signal lines 42 between the same two columns of first light-emitting units 211. This satisfies the requirement that both the read signal line 42 and the data signal line 41 are set in the first functional area 11, while still keeping the read signal line 42 and the data signal line 41 separated by the first light-emitting unit 211, thereby ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0118] In the original circuit layout setting of the first functional area 11, the data signal lines 41 of part of the first display circuit 31 and the read signal lines 42 of the functional circuit 33 are arranged between the same two columns of the first light-emitting units 211. By exchanging the positions of the data signal lines 41 arranged between the same two columns of the first light-emitting units 211 with the read signal lines 42 and the adjacent read signal lines 42, multiple read signal lines 42 are arranged between the same two columns of the first light-emitting units 211. The read signal lines 42 and the data signal lines 41 can still be kept separated by the first light-emitting units 211, thereby ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0119] Optionally, when the ratio of the number of the first light-emitting units 211 to the number of the functional units 22 in the functional component 20 is 2:1, the two first light-emitting units 211 are arranged side by side along the row direction X, and the functional unit 22 and the two first light-emitting units 211 are arranged side by side along the column direction Y, the ratio of the number of the data signal lines 41 to the number of the read signal lines 42 in the first functional area 11 is 2:1. In the original circuit layout setting of the first functional area 11, the signal lines 40 are arranged in the row direction X in the order of the data signal lines 41, the read signal lines 42, and the data signal lines 41 between the first light-emitting units 211.

[0120] The display panel 100 provided in the embodiment of the present application, by setting two read signal lines 42 between the same two columns of first light-emitting units 211, the signal lines are arranged in the row direction X between the first light-emitting units 211 in the order of, for example, two data signal lines 41, data signal line 41, two read signal lines 42 and data signal line 41. The embodiment of the present application can also arrange the signal lines 40 in the first functional area 11 in other orders, as long as the two read signal lines 42 are set between the same two columns of first light-emitting units 211.

[0121] In some embodiments, see Figure 5 and Figure 6 The first functional area 11 also includes a reserved circuit space 13 , the reserved circuit space 13 is arranged between two adjacent columns of first display circuits 31 , and the read signal line 42 is arranged in the reserved circuit space 13 .

[0122] The display panel 100 provided in the embodiment of the present application reserves part of the space between the first display circuits 31 in the first functional area 11 as a reserved circuit space 13, and sets the read signal line 42 in the reserved circuit space 13, which can increase the distance between the read signal line 42 and the data signal line 41, further ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0123] Optionally, since the layout of the first light-emitting unit 211 is unchanged, and the first display circuit 31 needs to be redesigned to allow some space to be set up for the reserved circuit space 13, there is a certain deviation and misalignment between the first display circuit 31 and the first light-emitting unit 211 in the orthographic projection direction of the display panel 100. When the deviation and misalignment are small, the electrodes of the first display circuit 31 and the first light-emitting unit 211 can still be connected through existing wiring. When the deviation and misalignment are large, additional wiring can also be set up between the first display circuit 31 and the electrodes of the first light-emitting unit 211 for connection, so as to ensure the connection effect between the electrodes of the first display circuit 31 and the first light-emitting unit 211.

[0124] In some optional embodiments, multiple first display circuits 31 are arranged in the first functional area 11 to form multiple first display circuit rows 37, and the same first display circuit row 37 is formed by repeatedly arranging first circuit repetition units 36 along the row direction, and the reserved circuit space 13 of the first functional area 11 is set in the first circuit repetition unit 36.

[0125] The display panel 100 provided in the embodiment of the present application sets the reserved circuit space 13 in the first circuit repetition unit 36, further reducing the impact on the first display circuit 31 originally set in the first functional area 11, and only needs to re-set the circuit layout in the first circuit repetition unit 36 ​​to make at least part of the space for setting the reserved circuit space 13, so that the distance between the adjusted first display circuit 31 and the first light-emitting unit 211 driven by it is closer, and the reserved circuit space 13 is evenly set in the first functional area 11, ensuring that the spacing between the read signal line 42 and the data signal line 41 is further uniform, further reducing the parasitic capacitance between the signal lines 40, so that the signal lines 40 do not crosstalk with each other, and further ensuring the normal operation of the first display circuit 31 and the functional circuit 33.

[0126] Similarly, in the first functional area 11, the first light-emitting units 211 are also arranged and combined in a certain order to form a specific pixel structure to achieve a better light-emitting effect. Optionally, a common light-emitting unit 21 combination includes a red sub-pixel light-emitting unit (R), a green sub-pixel light-emitting unit (G), a blue sub-pixel light-emitting unit (B) and a green sub-pixel light-emitting unit (G). At the same time, the first display circuit 31 corresponding to the first light-emitting unit 211 in the first functional area 11 is also formed in the first circuit repetition unit 36 ​​in the same row. The reserved circuit space 13 can be set between the second display circuit 32 for driving the G sub-pixel and the second display circuit 32 for driving the B sub-pixel, so that the distance between the adjusted second display circuit 32 and the second light-emitting unit 212 driven by it is closer, so that the same circuit layout design adjustment is performed in each second circuit repetition unit 34.

Since the display device provided by the embodiment of the present application includes the display panel 100 of any of the above embodiments, the display device provided by the embodiment of the second aspect of the present application has the beneficial effects of the display panel 100 of any of the above embodiments of the first aspect, which will not be repeated here.
