[0094] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0095] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.
[0096] As used herein, “approximately” or “substantially the same” includes the stated value and means within an acceptable range of deviations from the specific value, as determined by a person skilled in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., limitations of the measurement system). For example, “substantially the same” may mean a difference relative to the stated value within one or more standard deviations, or within ±30%, 20%, 10%, or 5%.
[0097] In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. Exemplary embodiments are described herein with reference to cross-sectional views that are schematic diagrams of idealized embodiments. Thus, deviations from the shapes shown in the drawings will be expected as a result of, for example, manufacturing techniques and / or tolerances. Therefore, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include deviations in shape caused, for example, by manufacturing processes. For example, regions illustrated or described as flat may typically have rough and / or non-linear characteristics. Furthermore, sharp corners illustrated may be rounded. Thus, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, nor are they intended to limit the scope of the claims.
[0098] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.
[0099] In low-temperature environments, the viscosity of liquid crystal is high, and the display screen needs an internal heating function to increase the liquid crystal temperature in order to display normally. Therefore, the power consumption will increase, especially for large screens with large areas. To ensure that the liquid crystal can work normally, even more power consumption is required. Excessive power consumption requires frequent charging, which will reduce the user experience.
[0100] In view of this, referring to Figure 1, this disclosure provides a display substrate having a display area AA and a peripheral area BB located around the display area AA; wherein, the display substrate includes:
[0101] Substrate 1;
[0102] The heating structure J is located on one side of the substrate 1 and includes: multiple first heating lines J1 and multiple second heating lines J2; the multiple first heating lines J1 are located in the display area AA, and the multiple second heating lines J2 are located in the peripheral area BB.
[0103] The first photosensitive structure S1 is located in the peripheral region BB. At least a portion of the first photosensitive structure S1 in the orthographic projection of the substrate 1 does not overlap with the orthographic projection of the second heating trace J2 in the substrate.
[0104] In this embodiment, the display substrate has multiple first heating traces J1 in the display area AA and multiple second heating traces J2 in the peripheral area BB. This enables heating of the display substrate and improves the problem of abnormal display due to liquid crystal viscosity at low temperatures. Furthermore, the display substrate also has a first light-sensing structure S1 in the peripheral area BB, which can detect ambient light and automatically adjust the brightness of the display product according to the ambient light, providing users with the best visual effect. In addition, the integration of the first light-sensing structure S1 and the heating structure J allows the display panel to display normally at low temperatures while also achieving low power consumption. This improves the problem that the display panel would have increased power consumption due to the heating structure J, requiring frequent charging and resulting in a poor user experience.
[0105] In one possible implementation, as shown in FIG10, a gate line layer (which may include multiple gate lines 2 extending along a first direction), a gate insulating layer, an active layer, a data line layer (which may include multiple data lines 3 extending along a second direction), a first passivation layer, a heating structure layer (which may include a heating structure J), a second passivation layer, a common electrode layer (which may be a transparent conductive layer), a third passivation layer, and a pixel electrode layer (which may include multiple pixel electrodes 4 and multiple auxiliary pixel electrodes 40) can be sequentially formed on the substrate 1. The above is only one film layer stacking structure of the display substrate provided in the embodiments of this disclosure. In specific implementations, the display substrate may also be stacked in other ways, and the embodiments of this disclosure are not limited here.
[0106] In one possible implementation, referring to Figures 1 and 2A-2E, where Figures 2A-2E are schematic diagrams of a single layer or stacked layers at the dashed box C1 in Figure 1, Figure 2A is a schematic diagram of a display substrate with a heating structure, Figure 2B is a schematic diagram of a display substrate without a heating structure, Figure 2C is a schematic diagram of a single layer with a heating structure, Figure 2D is a schematic diagram of a display panel with a black matrix layer, and Figure 2E is a schematic diagram of a single film layer of the black matrix layer. The peripheral area BB includes: a first peripheral area BB1, a second peripheral area BB2, a third peripheral area BB3, and a fourth peripheral area BB4; the first peripheral area BB1 and the fourth peripheral area BB4 are arranged opposite to each other, and the second peripheral area BB2 and the third peripheral area BB3 connect the first peripheral area BB1 and the fourth peripheral area BB4; for example, referring to Figure 1, the second peripheral area BB2 connects the left end of the first peripheral area BB1 and the left end of the fourth peripheral area BB4; the third peripheral area BB3 connects the right end of the first peripheral area BB1 and the right end of the fourth peripheral area BB4.

[0110] In one possible implementation, referring to FIG2F, the first photosensitive structure S1 (e.g., the first sub-photosensitive structure S11) includes: a plurality of first transistors T1; the plurality of first transistors T1 are connected in series; the first transistor T1 includes: a first control electrode T1A, a first source electrode T1B, and a first drain electrode T1C; the first control electrodes T1A of the plurality of first transistors T1 are connected to each other, the first sources T1B of the plurality of first transistors T1 are connected to each other, and the first drain electrodes T1C of the plurality of first transistors T1 are connected to each other.

[0113] In one possible implementation, the first sub-photosensitive structure S11 may include 80-120 first transistors connected in series; the first sub-control photosensitive structure S21 may include 80-120 second transistors connected in series.
[0114] In one possible implementation, the data line 3 is located on the side of the gate line 2 away from the substrate 1; the pixel electrode 4 is located on the side of the data line 3 away from the gate line 2; the first control electrode T1A, the second control electrode T2A, and the gate line 2 are in the same layer and made of the same material; the first source electrode T1B, the first drain electrode T1C, the second source electrode T2B, the second drain electrode T2C, and the data line 3 are in the same layer and made of the same material; the heating structure J is located between the layers where the data line 3 and the pixel electrode 4 are located. In this embodiment, the first control electrode T1A of the first photosensitive structure S1 and the second control electrode T2A of the second photosensitive structure S2 can be formed simultaneously with the formation of the gate line 2; the first source electrode T1B and the first drain electrode T1C of the first photosensitive structure S1, and the second source electrode T2B and the second drain electrode T2C of the second photosensitive structure S2 can be formed simultaneously with the formation of the data line 3. This simplifies the manufacturing process of the display substrate and reduces the manufacturing cost of the display substrate while enabling the detection of ambient light.
[0115] In one possible implementation, as shown in FIG2A, the display substrate further includes: a plurality of first sector-shaped trace groups F1; wherein the plurality of first sector-shaped trace groups F1 are located in a first peripheral area BB1; the first sector-shaped trace group F1 includes: a plurality of first leads F10; the first leads F10 are electrically connected to one end of the data line 3; and the first sub-photosensitive structure S11 is located in the gap between two adjacent first sector-shaped trace groups F1.
[0116] In this embodiment of the present disclosure, a first sub-light-sensing structure S11 can be provided in the first peripheral area BB1 of the display substrate, which can detect the ambient light at the location of the first peripheral area BB1. Moreover, the first sub-light-sensing structure S11 is located in the gap between two adjacent first fan-shaped trace groups F1, which can avoid the multiple first leads F10 of the first fan-shaped trace group F1 from blocking the external ambient light, so that the first sub-light-sensing structure S11 can effectively detect the ambient light at the location of the first peripheral area BB1.
[0117] In one possible implementation, referring to FIG2B, the first sector-shaped trace group F1 includes: a first sub-sector-shaped trace group F11 and a second sub-sector-shaped trace group F12; the second sub-sector-shaped trace group F12 is located on the side of the first sub-sector-shaped trace group F11 away from the display area AA; the first sub-sector-shaped trace group F11 includes: multiple first sub-leads F110; the second sub-sector-shaped trace group F12 includes: multiple second sub-leads F120;
[0118] The display substrate also includes: a plurality of first anti-static structures ESD1 and a plurality of first bonding groups DP; the first anti-static structures ESD1 are located between the first sub-fan-shaped trace group F11 and the second sub-fan-shaped trace group F12, and the first bonding groups DP are located on the side of the second sub-fan-shaped trace group F21 away from the first sub-fan-shaped trace group F11; the first anti-static structures ESD1 include: a plurality of first anti-static units ESD10 arranged along the first direction X; as shown in FIG1, the first bonding groups DP include: a plurality of first bonding terminals DP0 arranged along the first direction X;
[0119] One end of the first sub-lead F110 is connected to the data line 2, and the other end is electrically connected to one end of the first anti-static unit ESD10; one end of the second sub-lead F120 is electrically connected to the other end of the first anti-static unit ESD10, and the other end of the second sub-lead F120 is electrically connected to the first bonding terminal DP0.
[0120] The first sub-fan-shaped trace group F11 includes: a first outer edge e1 extending along the first direction X and away from the display area AA (the area above the dotted line in Figure 2B is the display area) (that is, the lower edge of the first sub-fan-shaped trace group F11); the second sub-fan-shaped trace group F12 includes: a second outer edge e2 extending along the first direction X and close to the display area AA (that is, the upper edge of the second sub-fan-shaped trace group F12); the first sub-light-sensing structure S11 is located in the area between the extension line of the first outer edge e1 and the extension line of the second outer edge e2.
[0121] In this embodiment of the present disclosure, the first sector-shaped trace group F1 includes: a first sub-sector-shaped trace group F11 and a second sub-sector-shaped trace group F12. That is, the first sector-shaped trace group F1 is divided into a first sub-sector-shaped trace group F11 and a second sub-sector-shaped trace group F12 along the second direction Y, so that there is more space between the two first sector-shaped trace groups F1 in the first direction X, so as to facilitate the setting of the first sub-photosensitive structure S11.
[0122] In one possible implementation, as shown in FIG2B, the display substrate further includes: a first common electrode 5 located on the side of the second sub-fan-shaped wiring group F12 away from the display area AA, and a plurality of first photosensitive leads 6 connected to the first sub-photosensitive structure S11.
[0123] The first light-sensing lead 6 connected to the first sub-light-sensing structure S11 includes: a first light-sensing trace 61; the first light-sensing trace 61 is located on the side of the first sub-light-sensing structure S1 away from the display area AA and extends along the second direction Y; specifically, the portion of the first light-sensing lead 6 that extends along the second direction Y can be used as the first light-sensing trace 61.
[0124] The first common electrode 5 includes a first sub-common electrode 51 and a second sub-common electrode 52 distributed along the first direction X; the first sub-common electrode 51 and the second sub-common electrode 52 are located on different sides of the first sub-photosensitive trace portion 61.
[0125] In this embodiment of the present disclosure, the first common electrode 5 includes a first sub-common electrode 51 and a second sub-common electrode 52 distributed along the first direction X. The first sub-common electrode 51 and the second sub-common electrode 52 are located on different sides of the first sub-photosensitive wiring portion 61, that is, the first common electrode 5 is divided into a first sub-common electrode 51 and a second sub-common electrode 52. In this way, the first photosensitive wiring portion 61 can run wiring from the middle of the first sub-common electrode 51 and the second sub-common electrode 52, and then connect to the bonding terminal of the first peripheral area BB1. This avoids the problem of increased signal line resistance caused by using other electrodes (e.g., electrodes of the common electrode layer or pixel electrode layer) for jumper connection when the first photosensitive lead 6 needs to cross the first common electrode 5, and prevents signal distortion during transmission.
[0126] In one possible implementation, as shown in FIG2B, the first sub-common electrode 51 and the second sub-common electrode 52 can be a mesh structure, and each can have multiple common openings 50.
[0127] In one possible implementation, as shown in FIG2B, the first photosensitive lead 6 includes: a first sub-photosensitive lead G1, a second sub-photosensitive lead S1, and a third sub-photosensitive lead D1; wherein, as shown in FIG2F, the first sub-photosensitive lead G1 can be connected to the first control electrode T1A of the first transistor T1, the second sub-photosensitive lead S1 can be connected to the first source electrode T1B of the first transistor T1, and the third sub-photosensitive lead D1 can be connected to the first drain electrode T1C of the first transistor T1;
[0128] The second sub-photosensitive lead S1, the third sub-photosensitive lead D1, the first sub-lead F110 and the data line 3 are in the same layer and made of the same material; the first sub-photosensitive lead G1, the second sub-lead F120, the first common electrode 5 and the gate line 2 are in the same layer and made of the same material.
[0129] In one possible implementation, as shown in FIG2B, the first photosensitive lead 6 may further include: a fourth sub-photosensitive lead G2, a fifth sub-photosensitive lead S2, and a sixth sub-photosensitive lead D2; wherein, as shown in FIG2F, the fourth sub-photosensitive lead G2 may be connected to the first control electrode T2A of the second transistor T2, the fifth sub-photosensitive lead S2 may be connected to the first source electrode T2B of the second transistor T2, and the sixth sub-photosensitive lead D2 may be connected to the first drain electrode T2C of the second transistor T2; the fourth sub-photosensitive lead G2 is in the same layer and made of the same material as the first sub-photosensitive lead G1; the fifth sub-photosensitive lead S2 and the sixth sub-photosensitive lead D2 are in the same layer and made of the same material as the second sub-photosensitive lead S1.
[0130] In one possible implementation, as shown in Figure 2B, the first sub-control light-sensing structure S21 is located on the side of the first sub-control light-sensing structure S11 away from the display area AA, and the two are distributed in two rows with their ends aligned; the first light-sensing leads 6 (such as the first sub-light-sensing lead G1, the second sub-light-sensing lead S1, and the third sub-light-sensing lead D1) connected to the first sub-control light-sensing structure S11 can be led out from one end of the first fan-shaped wiring group F1 near one side (such as the left side) of the first sub-control light-sensing structure S11, and connected to the first sub-control light-sensing structure S11. The first photosensitive lead 6 (such as the fourth sub-photosensitive lead G2, the fifth sub-photosensitive lead S2, and the sixth sub-photosensitive lead D2) connected to the photosensitive structure S21 can be led out from one end of the first fan-shaped trace group F1 near the other side (such as the right side) of the first sub-reference photosensitive structure S21. The two are distributed in a roughly symmetrical manner to avoid the problem of increased resistance of the first photosensitive lead 6 due to winding if all the first photosensitive leads 6 are set on the same side of the first sub-photosensitive structure S11 (or the first sub-reference photosensitive structure S21).
[0131] In one possible implementation, as shown in FIG2B, the display substrate further includes: a plurality of floating pixel electrodes 40 located in the first peripheral region BB1 and arranged along the first direction X; the length d2 of the floating pixel electrodes 40 in the second direction Y is one-quarter to three-quarters of the length d1 of the pixel electrode 4 in the second direction Y; optionally, the length d2 of the floating pixel electrodes 40 in the second direction Y is one-half of the length d1 of the pixel electrode 4 in the second direction Y. In this embodiment of the present disclosure, by compressing the length d2 of the floating pixel electrodes 40 in the second direction Y, more space is provided for the setting of the first sub-photosensitive structure S11 in the second direction Y, thereby enabling the first sub-photosensitive structure S11 to be placed within the second opening VA (the second opening VA can be the opening area of the ink on the cover plate).
[0132] In one possible implementation, as shown in Figures 2A and 2C, the plurality of second heating traces J2 include: a plurality of first sub-heating traces J21; the plurality of first sub-heating traces J21 extend along a first direction X and are arranged sequentially along a second direction Y, and the plurality of first sub-heating traces J21 are located on the side of the first sub-photosensitive structure S11 away from the display area AA; the line width j21 of the first sub-heating traces J21 is greater than the line width j1 of the first heating traces J1.
[0133] In this embodiment, multiple first sub-heating traces J21 are located on the side of the first sub-photosensitive structure S11 away from the display area AA, so as to avoid the first sub-photosensitive structure S11 and achieve unobstructed view of the first sub-photosensitive structure S11. Moreover, since the peripheral area BB dissipates heat faster, when the peripheral area BB is at a lower temperature, the area of the display area AA near the peripheral area BB is more prone to display defects due to liquid crystal viscosity. By setting the line width j21 of the first sub-heating trace J21 to be greater than the line width j1 of the first heating trace J1, the heat of the peripheral area BB (first peripheral area BB1) can be increased faster, thus improving the problem that the area of the display area AA near the peripheral area BB is more prone to display defects when the temperature is low.
[0134] In one possible implementation, as shown in Figures 2A and 2B, multiple first sub-heating traces J21 are located on the side of the first sub-reference photosensitive structure S21 away from the display area AA. This allows the multiple first sub-heating traces J21 to avoid the first sub-reference photosensitive structure S21, achieving unobstructed view of the first sub-reference photosensitive structure S21. Furthermore, the first sub-reference photosensitive structure S21 and the first sub-photosensitive structure S11 have substantially the same peripheral structure on the display substrate side, except for differences in their corresponding configurations in the black matrix layer, thereby improving detection accuracy.
[0135] In one possible implementation, referring to Figures 1 and 3A-3E, Figures 3A-3E are schematic diagrams of a single layer or stacked layer at the dashed frame C2 in Figure 1, Figure 3A is a schematic diagram of the display substrate with a heating structure, Figure 3B is a schematic diagram of the display substrate without a heating structure, Figure 3C is a schematic diagram of a single layer with a heating structure, Figure 3D is a schematic diagram of the display panel with a black matrix layer, and Figure 3E is a schematic diagram of a single film layer of the black matrix layer. Referring to Figure 1, the display substrate further includes: a plurality of second fan-shaped wiring groups F2; the plurality of second fan-shaped wiring groups F2 are located in the second peripheral area B2; referring to Figures 3A and 3B, the second fan-shaped wiring group F2 includes: a plurality of second leads F20; the second leads F20 are connected to one end of the gate line 2; the first photosensitive structure S1 further includes: a second sub-photosensitive structure S12; the second sub-photosensitive structure S12 is located in the second peripheral area BB2 and is located in the gap between two adjacent second fan-shaped wiring groups F2.
[0136] In this embodiment of the present disclosure, a second sub-light-sensing structure S12 can be provided in the second peripheral area BB2 of the display substrate, which can realize the detection of ambient light at the location of the second peripheral area BB2. Moreover, the second sub-light-sensing structure S12 is located in the gap between two adjacent second fan-shaped trace groups F2, which can avoid the multiple second leads F20 of the second fan-shaped trace group F2 from blocking the external ambient light, so that the second sub-light-sensing structure S12 can effectively detect the ambient light at the location of the second peripheral area BB2.
[0137] In one possible implementation, as shown in FIG3B, the second photosensitive structure S2 may include: a second sub-reference photosensitive structure S22 located on the side of the second sub-photosensitive structure S12 away from the display area AA; when the display substrate is applied to the display panel, as shown in FIG3D and FIG3E, the orthographic projection of the first opening BMK on the substrate overlaps with the orthographic projection of the first photosensitive structure S1 (e.g., the second sub-photosensitive structure S12) on the substrate, that is, the second sub-photosensitive structure S12 can be disposed at the first opening BMK to achieve effective detection of external light; the orthographic projection of the blocking portion BM1 on the substrate covers the orthographic projection of the second photosensitive structure S2 (e.g., the second sub-reference photosensitive structure S22) on the substrate, that is, the first sub-reference photosensitive structure S12 is blocked from light so that the second sub-photosensitive structure S12 is used for detection and the second sub-reference photosensitive structure S22 is used as a reference, thereby eliminating the leakage current caused by other factors from being miscalculated as optical leakage current and affecting the detection accuracy.
[0138] In one possible implementation, as shown in FIG3B, the plurality of second heating traces J2 include: a plurality of second sub-heating traces J22; the plurality of second sub-heating traces J22 are located in the second peripheral region BB2 and extend along the second direction Y and are arranged sequentially along the first direction X; as shown in FIG3C, the linewidth j22 of the second sub-heating traces J22 is greater than the linewidth of the first heating trace j1; at least a portion of the second sub-photosensitive structure S12 projected onto the substrate 1 (e.g., it may be an active pattern in the second sub-photosensitive structure S12) is located within the orthographic projection of the substrate 1 in the gap between two adjacent second sub-heating traces J22; optionally, the entire second sub-photosensitive structure S12 projected onto the substrate 1 is located within the orthographic projection of the substrate 1 in the gap between two adjacent second sub-heating traces J22.
[0139] In this embodiment, at least a portion of the second sub-photosensitive structure S12 projected onto the substrate 1 is located within the gap between two adjacent second sub-heating traces J22, in order to avoid obstructing the first sub-photosensitive structure S11. Moreover, since the peripheral area BB dissipates heat faster, the area near the peripheral area BB in the display area AA is more prone to display defects due to liquid crystal viscosity when the temperature is low. By setting the linewidth j22 of the second sub-heating trace J22 to be greater than the linewidth of the first heating trace j1, the heat of the peripheral area BB (second peripheral area BB1) can be increased faster, thus improving the problem that the area near the peripheral area BB in the display area AA is more prone to display defects when the temperature is low.
[0140] In one possible implementation, referring to Figures 1 and 4, Figure 4 can be an enlarged schematic diagram of Figure 1 at the dashed frame C3. The display substrate further includes: a plurality of third sector-shaped trace groups F3; the plurality of third sector-shaped trace groups F3 are located in the third peripheral area BB3; the third sector-shaped trace group F3 includes: a plurality of third leads F30; the third leads F30 are connected to the other end of the gate line 2; the first photosensitive structure S1 includes: a third sub-photosensitive structure S12; the third sub-photosensitive structure S13 is located in the third peripheral area BB3 and is located in the gap between two adjacent third sector-shaped trace groups F3.
[0141] In this embodiment of the present disclosure, a third sub-light-sensing structure S13 can be provided in the third peripheral area BB3 of the display substrate, which can realize the detection of ambient light at the location of the third peripheral area BB3. Moreover, the third sub-light-sensing structure S13 is located in the gap between two adjacent third fan-shaped trace groups F3, which can avoid the multiple third leads F30 of the third fan-shaped trace group F3 from blocking the external ambient light, so that the third sub-light-sensing structure S13 can effectively detect the ambient light at the location of the third peripheral area BB3.
[0142] In one possible implementation, as shown in FIG4, the second photosensitive structure S2 may include: a third sub-reference photosensitive structure S23 located on the side of the third sub-photosensitive structure S13 away from the display area AA; when the display substrate is applied to the display panel, the orthographic projection of the first opening BMK on the substrate overlaps with the orthographic projection of the first photosensitive structure S1 (e.g., the third sub-reference photosensitive structure S13) on the substrate, that is, the third sub-reference photosensitive structure S13 can be disposed at the first opening BMK to achieve effective detection of external light; the orthographic projection of the blocking portion BM1 on the substrate covers the orthographic projection of the second photosensitive structure S2 (e.g., the third sub-reference photosensitive structure S23) on the substrate, that is, the third sub-reference photosensitive structure S13 is blocked from light so that the third sub-reference photosensitive structure S13 is used for detection and the third sub-reference photosensitive structure S23 is used as a reference, thereby eliminating the leakage current caused by other factors from being mistakenly calculated as optical leakage current and affecting the detection accuracy.
[0143] In one possible implementation, as shown in Figures 1 and 4, the plurality of second heating traces J2 include: a plurality of third sub-heating traces J23; the plurality of third sub-heating traces J23 are located in the third peripheral region BB3 and extend along the second direction Y and are arranged sequentially along the first direction X; at least a portion of the third sub-photosensitive structure S13 in the orthographic projection of the substrate 1 (e.g., it may be an active pattern in the third sub-photosensitive structure S13) is located in the gap between two adjacent third sub-heating traces J23 within the orthographic projection of the substrate 1.
[0144] In one possible implementation, referring to Figures 1 and 5A-5D, Figures 5A-5D are schematic diagrams of a single layer or stacked layers at the dashed frame C4 in Figure 1, Figure 5A is a schematic diagram of the display substrate with a heating structure, Figure 5B is a schematic diagram of a single layer of the heating structure, Figure 5C is a schematic diagram of the display panel with a black matrix layer, and Figure 5D is a schematic diagram of a single film layer of the black matrix layer. The display substrate further includes: multiple fourth fan-shaped wiring groups F4; the multiple fourth fan-shaped wiring groups F4 are located in the fourth peripheral area BB4; the fourth fan-shaped wiring group F4 includes: multiple fourth leads F40; one end of the fourth lead F40 is connected to one end of the first heating wiring J1; the first photosensitive structure S1 includes: a fourth sub-photosensitive structure S14; the fourth sub-photosensitive structure S14 is located in the fourth peripheral area BB4 and is located on the side of the fourth fan-shaped wiring group F4 facing the display area AA.
[0145] In this embodiment, a fourth sub-light-sensing structure S14 can be provided in the fourth peripheral area BB4 of the display substrate, which can detect the ambient light at the location of the fourth peripheral area BB4. Moreover, the fourth sub-light-sensing structure S14 is located in the gap between two adjacent fourth fan-shaped trace groups F4, which can avoid the multiple fourth leads F40 of the fourth fan-shaped trace group F4 from blocking the external ambient light, so that the fourth sub-light-sensing structure S14 can effectively detect the ambient light at the location of the fourth peripheral area BB4.
[0146] In one possible implementation, as shown in FIG5A, the second photosensitive structure S2 may include a fourth sub-reference photosensitive structure S24, which may be located in the same row as the fourth sub-reference photosensitive structure S14. When the display substrate is applied to the display panel, the orthogonal projection of the blocking portion BM1 onto the substrate covers the orthogonal projection of the second photosensitive structure S2 (e.g., the fourth sub-reference photosensitive structure S24) onto the substrate. That is, the fourth sub-reference photosensitive structure S24 is shielded from light so that the fourth sub-reference photosensitive structure S14 is used as a detector and the fourth sub-reference photosensitive structure S24 is used as a reference, thereby eliminating the leakage current caused by other factors from being mistakenly calculated as optical leakage current and affecting the detection accuracy.
[0147] In one possible implementation, as shown in Figures 5C and 5D, the first opening BMK can have multiple sub-openings BMK0, with a shielding portion BM1 between adjacent sub-openings BMK0. This is to prevent metallic reflection from occurring under strong light when the fourth sub-light-sensing structure S24 and the fourth sub-light-sensing structure S14 are designed in the same row. If a long strip of the first opening BMK is set at the position of the fourth sub-light-sensing structure S14, it will reduce the contrast and affect the product experience. Therefore, in order to reduce the impact of metallic reflection, the first opening BMK can have multiple sub-openings BMK0. That is, there is a gap between the two first transistors T1, and the position between the first transistors T1 is shielded by the shielding portion BM1. In this way, the grooves in the black matrix layer at this position are some intermittent small holes, which can reduce the metallic reflection effect and improve the product display effect.
[0148] In one possible implementation, as shown in Figures 2A, 2C, 5A, and 5B, the display substrate includes: a plurality of pixel electrode columns extending along the second direction Y and arranged along the first direction X, and a plurality of first heating trace groups JZ arranged along the first direction X. Figure 2C can be a schematic diagram of the first heating trace group JZ near the first peripheral region BB1, and Figure 5B can be a schematic diagram of the first heating trace group JZ near the fourth peripheral region BB4. The pixel electrode columns include: a plurality of pixel electrodes 4 arranged along the second direction Y. The first heating trace group JZ includes: a plurality of first heating traces J1. The orthographic projection of the first heating trace J1 onto the substrate 1 is located at the orthographic projection of the gap between a portion of two adjacent pixel electrode columns onto the substrate 1. Optionally, each pixel (a pixel may include three sub-pixels) may have one first heating trace J1. In the same first heating trace group JZ, the ends of each first heating trace J1 near the first peripheral region BB1 are electrically connected, and the ends of some adjacent first heating traces J1 near the fourth peripheral region BB4 are electrically connected.
[0149] In this embodiment of the disclosure, the display substrate has multiple first heating trace groups JZ. In the same first heating trace group JZ, the ends of each first heating trace J1 near the first peripheral area BB1 are electrically connected, and the ends of some adjacent first heating traces J1 near the fourth peripheral area BB4 are electrically connected. That is, by connecting some of the first heating traces J1 in parallel, the density of the first heating traces J1 can be reduced. Therefore, the spacing between the first heating traces J1 coming out of the display area AA is large, and the fourth sub-photosensitive structure S14 can be placed between the heating wire straight fan-out.
[0150] For large-size screens, due to bonding and other processes, the chip-on-flex (COF) film for heating is required to be segmented, meaning multiple COFs are bonded separately. This results in uneven heating temperatures between the COFs. In other words, in related technologies, the area between the two fourth sector groups F4 is not designed with heating wires. Since the edge area dissipates heat faster than the center area, the area between the two fourth sector groups F4 lacks heating wires to supplement the heat of this area. As a result, the temperature of the display area AA near this area rises lower than that inside the display area AA, leading to uneven temperature distribution in the display area AA and causing low-temperature display problems. In view of this, referring to Figures 6A, 6B, 7A, and 7B, where Figure 6B is an enlarged view of Figure 6A at the dashed box C5, and Figure 7B is an enlarged view of Figure 7A at the dashed box C6, the display substrate also includes: a plurality of fourth bonding groups RP located in the fourth peripheral area BB4; the fourth bonding group RP includes: a plurality of fourth bonding terminals R-P0 arranged along the first direction X; the other end of the fourth lead F40 is electrically connected to the fourth bonding terminal R-P0; the plurality of second heating traces J2 also include: auxiliary heating traces JF; the auxiliary heating traces JF are located between two adjacent fourth sector trace groups RP.
[0151] In this embodiment of the present disclosure, the multiple second heating traces J2 further include: auxiliary heating traces JF; the auxiliary heating traces JF are located between two adjacent fourth sector trace groups RP, which can heat the area between the two adjacent fourth sector trace groups RP, improve the phenomenon that the temperature rise of the display area AA near this area is lower than that inside the display area AA, resulting in uneven temperature of the display area AA and causing poor low-temperature display.
[0152] In one possible implementation, referring to Figures 6A and 6B, the fourth bonding group RP further includes: a fifth bonding terminal R-P1; the auxiliary heating trace JF includes: a first auxiliary heating trace J24; one end of the first auxiliary heating trace J24 is electrically connected to the fifth bonding terminal R-P1 of the RP in one fourth bonding group, and the other end is electrically connected to the fifth bonding terminal R-P1 of another fourth bonding group RP;
[0153] The first auxiliary heating wiring J24 includes: a plurality of first winding units D1 arranged along the first direction X and interconnected with each other; the first winding unit D1 includes: two first winding portions D11 extending along the second direction Y, and a first connecting portion D12 connecting the two first winding portions D11 away from the end of the display area AA.
[0154] In the first auxiliary heating wiring J24, the extension lines of the first connecting portions D12 of each first winding unit D1 coincide; and in the direction from the middle region of two adjacent fourth sector wiring groups F4 to a fourth sector wiring group F4 (as indicated by arrow E in Figure 6B), the length of each first winding unit D11 in the second direction Y gradually decreases. For example, in Figure 6B, the length g1 of the first winding unit D11 on the right in the second direction Y is less than the length g2 of the first winding unit D11 on the left in the second direction Y.
[0155] In this embodiment, the first auxiliary heating trace J24 includes: a plurality of first winding units D1; each first winding unit D1 includes: the extension lines of the first connecting portion D12 of each first winding unit D1 coincide; and in the direction from the middle region of two adjacent fourth sector trace groups F4 to a fourth sector trace group F4, the length of each first winding unit D11 in the second direction Y gradually decreases, so that the first auxiliary heating trace J24 and the region between two adjacent fourth sector trace groups F4 can complement each other, thereby achieving effective heating of the region between the two fourth sector trace groups F4.
[0156] As shown in Figures 6A and 6B, an auxiliary heating wire (i.e., the first auxiliary heating wire J24) is designed between two adjacent fourth sector wiring groups F4. The positive and negative electrodes that input signals to the auxiliary heating wire come from the two fourth binding groups RP respectively, and the positive and negative electrodes can be exchanged.
[0157] In one possible implementation, as shown in Figures 7A and 7B, the display substrate further includes: a first axis k1 extending along the second direction Y and passing through the gap between adjacent fourth bonding groups RP; the fourth bonding group RP further includes: a fifth bonding terminal R-P2 and a sixth bonding terminal R-P3;
[0158] The auxiliary heating trace JF also includes: a second auxiliary heating trace J25 and a third auxiliary heating trace J26; the second auxiliary heating trace J25 is located in the area between the first axis k1 and a fourth binding group RP (the fourth binding group RP on the left in Figure 7A), and the third auxiliary heating trace J26 is located in the area between the first axis k1 and another fourth binding group RP (the fourth binding group RP on the right in Figure 7A); one end of the second auxiliary heating trace J25 is electrically connected to the fifth binding terminal R-P2 in the fourth binding group RP (the fourth binding group RP on the left in Figure 7A), and the other end is electrically connected to the sixth binding terminal R-P3 in the same fourth binding group RP (the fourth binding group RP on the left in Figure 7A); one end of the third auxiliary heating trace J26 is electrically connected to the fifth binding terminal R-P2 in another fourth binding group RP (the fourth binding group RP on the right in Figure 7A), and the other end of the third auxiliary heating trace J26 is electrically connected to the sixth binding terminal R-P3 in the same fourth binding group RP (the fourth binding group RP on the right in Figure 7A).
[0159] In the disclosed embodiments shown in Figures 7A and 7B, two sets of heating wires (second auxiliary heating wire J25 and third auxiliary heating wire J26) are arranged between two adjacent fourth sector wiring groups F4 for heating. The two terminals that input signals to the second auxiliary heating wire J25 are on the same fourth bonding terminal group RP (for example, the fourth bonding group RP on the left in Figure 7A), and are respectively positive and negative electrodes. The positive and negative electrodes (terminals of the third auxiliary heating wire J26) are on another fourth bonding terminal group RP (for example, the fourth bonding group RP on the right in Figure 7A). The second auxiliary heating wire J25 and the third auxiliary heating wire J26 are connected in parallel with the first heating wire J1 of each display area AA, and are driven by constant voltage.
[0160] In one possible implementation, as shown in FIG7B, the second auxiliary heating line J25 and the third auxiliary heating line J26 each include: a plurality of second winding units D2 arranged and interconnected along the first direction X, and a plurality of third winding units D3 arranged and interconnected along the first direction X.
[0161] The second winding unit D2 includes two second winding portions D21 extending along the second direction Y, and a second connecting portion D22 connecting the two third winding portions D21 at the ends away from the display area AA; the third winding unit D3 includes two third winding portions D31 extending along the second direction Y, and a third connecting portion D32 connecting the two third winding portions D31 at the ends away from the display area AA; the second winding unit D2 is located on the side of the third winding unit D3 away from the display area AA, and the two are nested together;
[0162] In the second auxiliary heating wiring J25 and the third auxiliary heating wiring J26, the extension lines e3 of the second connecting part D22 of each second winding unit D2 coincide, and the extension lines e4 of the third connecting part D32 of each third winding unit D3 coincide; and in the direction from the first axis k1 to the fourth sector wiring group F4 (as indicated by arrow E in Figure 7B), the length g3 of each second winding unit D2 in the second direction Y gradually decreases, and the length g4 of each third winding unit D3 in the second direction Y gradually decreases.

[0164] Based on the same inventive concept, embodiments of this disclosure also provide a display panel, which includes a display substrate as provided in embodiments of this disclosure.
[0165] In related technologies, the required temperature rise for internal heating varies under different low-temperature environments. For example, at -40℃, a 30℃ temperature rise within 1 minute is needed to prevent video trailing; at -30℃, a 20℃ temperature rise within 1 minute is required for the same effect. The power consumption required to achieve the same effect in these two different environments differs. Commonly, power adjustment is achieved using pulse width modulation (PWM) circuits. PWM involves generating a square wave of a certain frequency and adjusting its duty cycle to adjust the power output. Changing the heating power during the heating process can also be achieved using PWM; adjusting the PWM pulse width or frequency to change the PWM period alters the output power. However, since PWM is an AC signal, it can interfere with the display substrate signal in the display area, causing horizontal lines, flickering, and other undesirable image quality. Using DC voltage avoids this problem, but the system terminal voltage is fixed and cannot be changed.
[0166] In view of this, referring to Figures 8A-8C, the display panel includes multiple heating circuits JO and multiple fourth bonding terminal pairs R-PO; each fourth bonding terminal pair R-PO includes two adjacent fourth bonding terminals R-P0; one end of the heating circuit JO is electrically connected to one of the fourth bonding terminals R-P0 of the fourth bonding terminal pair R-PO, and the other end of the heating circuit JO is electrically connected to the other fourth bonding terminal R-P0 of the fourth bonding terminal pair R-PO; the heating circuit JO includes: at least two first heating traces J1; at least a portion of the heating circuit JO is electrically connected. Optionally, the heating circuit JO may include a first heating trace group JZ as shown in Figures 2C and 5B; optionally, one first heating trace group JZ may serve as one heating circuit JO.
[0167] In this embodiment, the display panel includes multiple heating circuits JO and multiple fourth bonding terminal pairs R-PO; the heating circuit JO includes at least two first heating traces J1; at least a portion of the heating circuits JO are electrically connected, which can enable the heating structure J to form multiple heating levels, allowing the display panel to perform different heating levels according to the specific temperature environment. Moreover, it can avoid the interference of PWM modulation on the display substrate signal in the display area, thereby causing poor images such as horizontal stripes and flickering, as well as the problem that the DC voltage cannot be changed after the system terminal voltage is fixed, making it impossible to perform heating at different levels.
[0168] In one possible implementation, referring to FIG8A, the display panel further includes a third transistor T3 connected to at least a portion of the heating circuit JO, and M first connection lines SW1; the third transistor T3 includes: a third control electrode T3A, a third source electrode T3B, and a third drain electrode T3C; the third source electrode T3B and the third drain electrode T3C of the third transistor T3 are connected in the heating circuit JO, and the third control electrode T3A of the third transistor T3 every M heating circuit JO is connected to a first connection line SW1, and the third control electrode T3A of the third transistor T3 of adjacent heating circuit JO is sequentially connected to different first connection lines SW1.
[0169] In one possible implementation, referring to Figure 8A, the display panel can have four heating levels. All heating circuits JO in the display area AA of the display panel can be grouped into multiple circuit groups JOZ (Figure 8A illustrates this with two circuit groups JOZ). Each circuit group JOZ includes: a first heating circuit JO1, a second heating circuit JO2, a third heating circuit JO3, and a fourth heating circuit JO4. The first heating circuit JO1, the second heating circuit JO2, and the third heating circuit JO3 are all connected to a third transistor T3, while the fourth heating circuit JO4 may not be connected. The third transistor T3 of the first heating circuit JO1 in each circuit group JOZ is connected to the same first connection line SW1 (as shown in the rightmost first connection line SW1 in Figure 8A); the third transistor T3 of the second heating circuit JO2 in each circuit group JOZ is connected to another first connection line SW1 (as shown in the middle first connection line SW1 in Figure 8A); the third transistor T3 of the third heating circuit JO3 in each circuit group JOZ is connected to another first connection line SW1 (as shown in the leftmost first connection line SW1 in Figure 8A). In this way, the display panel can have four heating power levels, each with the same DC voltage. When all three first connection lines SW1 are turned on, the eight heating circuits JO are connected in parallel, and the power is P1 according to P=U*U / R. When the leftmost first connection line SW1 is turned off, the first heating circuit JO1 in each circuit group JOZ cannot form a loop and therefore cannot heat. At this time, the heating wire power is 0.75*P1. Similarly, when the leftmost and rightmost first connection lines SW1 are both turned off, the heating wire power is 0.5*P1. When all three first connection lines SW1 are turned off, the heating wire power is 0.25*P1. When designing the span of each circuit group JOZ, the heating radiation range needs to be considered, especially ensuring the heating wire radiation range at 0.25*P1. Different levels can be used according to customer needs to control the heating time. Higher power means shorter heating time. Using different levels according to the customer's usage environment can reduce power and save energy.
[0170] In one possible implementation, referring to FIG8B, the display panel further includes: a first flexible circuit board FPC; the first flexible circuit board FPC includes: M second connecting lines SW2 and a third connecting line SW3; one of the fourth bonding terminals R-PO of each M heating circuit JO connected to a fourth bonding terminal pair R-PO is connected to a second connecting line SW2, and the fourth bonding terminals R-P0 of adjacent heating circuit JO are connected to different second connecting lines SW2; the other fourth bonding terminal R-P0 of each heating circuit JO connected to a fourth bonding terminal pair R-PO is connected to a third connecting line SW3.
[0171] In one possible implementation, referring to Figure 8B, the display panel can have four heating levels. All heating circuits JO in the display area AA of the display panel can be grouped into multiple circuit groups JOZ (Figure 8B illustrates this with two circuit groups JOZ). Each circuit group JOZ includes: a first heating circuit JO1, a second heating circuit JO2, a third heating circuit JO3, and a fourth heating circuit JO4. One of the fourth bonding terminals R-P0 of the first heating circuit JO1 in each circuit group JOZ is connected to the same second connecting line SW1 (as shown in Figure 8A, the first second connecting line SW2 from the left). The second heating circuit in each circuit group JOZ... One of the fourth bonding terminals R-P0 of loop JO2 is connected to another second connecting line SW1 (as shown in Figure 8A, the second second connecting line SW2 from the left). In each loop group JOZ, one of the fourth bonding terminals R-P0 of the third heating loop JO3 is connected to another second connecting line SW1 (as shown in Figure 8A, the third second connecting line SW2 from the left). In each loop group JOZ, one of the fourth bonding terminals R-P0 of the fourth heating loop JO4 is connected to another second connecting line SW1 (as shown in Figure 8A, the fourth second connecting line SW2 from the left). In all loop groups JOZ, the other fourth bonding terminal R-P0 (such as the fourth bonding terminal R-P0 of the negative electrode) is connected to the third connecting line SW3. Thus, by grouping and paralleling the fourth bonding terminal of the display panel to R-PO on the first flexible circuit board (FPC), the number of heating wire groups that can be turned on can be adjusted according to customer needs. For example: when all four second connection lines SW2 are turned on, all heating circuits JO are working, and the heating power is P; when the first second connection line SW2 from the left is turned on, the first heating circuit JO1 in each circuit group JOZ works to heat, and the heating wire power is 1 / 4*P; when the first second connection line SW2 from the left and the third second connection line SW2 from the left are turned on, the first heating circuit JO1 and the third heating circuit JO3 in each circuit group JOZ work to heat, and the heating wire power is 1 / 2*P; in the above three methods, the heating circuits JO are evenly distributed when working. When achieving 3 / 4*P power, the activated heating circuits JO cannot be evenly distributed in the display area. However, as long as the radiation range at 1 / 4*P is well controlled, since the radiation range of the heating wire is the largest and the power is the smallest at 1 / 4*P, as long as the heating is uniform at 1 / 4*P, even though the working heating wires are not evenly distributed at 3 / 4*P, the heat from the heating wires is sufficient to ensure the normal display. More heating circuits JO can be designed in each circuit group JOZ as needed. The above four groups are just examples, and this disclosure is not limited to them.
[0172] In one possible implementation, referring to FIG8C, the display panel further includes: a first flexible circuit board FPC; the first flexible circuit board FPC includes: a fourth connecting line SW4, a fifth connecting line SW5, a sixth connecting line SW6, and a plurality of first control components G1 and a plurality of second control components G2; the first control components G1 and the second control components G2 each include: a first terminal GA and a second terminal GB.
[0173] In each of the fourth bonding terminal pairs R-PO, one of the fourth bonding terminals R-P0 is connected to the fourth connecting line SW4;
[0174] Each fourth bonding terminal in R-PO is alternately connected to the first terminal GA of the first control component G1 and the first terminal GA of the second control component G2;
[0175] The second terminal GB of each first control component G1 is connected to the fifth connection line SW5, and the second terminal GB of each second control component G2 is connected to the sixth connection line SW6.
[0176] In one possible implementation, as shown in FIG8C, the first control component G1 and the second control component G2 each include: a first resistor R, a first trace L, and a first switch K1.
[0177] One end of the first resistor R (as shown on the left) and one end of the first trace L (as shown on the left) are both electrically connected to the first end GA;
[0178] One end of the first switch K in the first control component G1 is electrically connected to the fifth connecting line SW5; the other end of the first switch K in the first control component G1 can be connected to the other end (such as the right end) of the first resistor R or the other end (such as the right end) of the first line L at different times.
[0179] One end of the first switch K in the second control component G2 is electrically connected to the sixth connecting line SW6; the other end of the first switch in the second control component can be connected to the other end of the first resistor or the other end of the first line at different times.
[0180] In the heating circuit shown in Figure 8C, the heating wires of the display area AA are divided into two groups on the first flexible circuit board (FPC). Two settings are designed on each heating circuit JO: one with a resistor R connected in series, and the other without a resistor (i.e., the first trace L). The power is controlled by adjusting the number of groups and settings as needed. When the fifth connection line SW5 and the sixth connection line SW6 are both open and the switch K is connected to the first trace L, all heating circuits JO are working, meaning all heating circuits JO are connected in parallel, resulting in minimum resistance and maximum power P. When the fifth connection line SW5 is open and the switch K is connected to the first trace L, or when the sixth connection line SW6 is open and the switch K is connected to the first resistor R, half of the heating circuits are operating. When circuit JO is working, the power is 1 / 2P. The first resistor R in series is the same as the resistance of each heating circuit JO. When the fifth connecting line SW5 is turned on and the switch K is connected to the first resistor R, half of the heating circuits JO are connected in series with a resistor element (i.e., the first resistor R) with the same resistance as the heating circuit JO. At this time, the heating wire power is 1 / 4P. When the fifth connecting line SW5 is turned on and the switch K is connected to the first resistor R, and when the sixth connecting line SW6 is turned on and the switch K is connected to the first trace L, the power is 3 / 4P. The required power can be adjusted by adjusting the resistance value of the series resistor. This embodiment is not limited to designing two levels on the heating circuit JO; it can have multiple levels, and the power can be subdivided. The advantage of this embodiment is that the heating circuits JO working in the display area AA are all evenly distributed in the display area AA.
[0181] In one possible implementation, referring to FIG9, the display panel further includes: a cover plate 300 located on the side of the opposing substrate 200 away from the display substrate 100; the cover plate 300 is provided with ink 301 on the side facing the opposing substrate 200; the ink has a second opening VA, and a first photosensitive structure S1 is located in the second opening VA.
[0182] In some embodiments, the display panel provided in this disclosure may further include a liquid crystal layer between a display substrate and a counter substrate, a first polarizer on the side of the array substrate away from the counter substrate, and a second polarizer on the side of the counter substrate away from the array substrate, wherein the polarization direction of the first polarizer and the polarization direction of the second polarizer are perpendicular to each other. Other essential components of the display panel are understood by those skilled in the art and will not be described in detail here, nor should they be construed as limiting the scope of this disclosure.
[0183] Based on the same inventive concept, this disclosure also provides a display device, comprising the display panel described above and a backlight module located on the light-incident side of the display panel. The backlight module can be a direct-lit backlight module or an edge-lit backlight module. Optionally, the edge-lit backlight module may include LED strips, stacked reflective sheets, light guide plates, diffusers, prism groups, etc., with the LED strips located on one side of the thickness direction of the light guide plate. The direct-lit backlight module may include a matrix light source, a reflective sheet, a diffuser plate, and a brightness enhancement film stacked on the light-emitting side of the matrix light source, with the reflective sheet including openings directly opposite the positions of the LEDs in the matrix light source. The LEDs in the LED strips and the LEDs in the matrix light source can be light-emitting diodes (LEDs), such as miniature LEDs (Mini LEDs, Micro LEDs, etc.).
[0184] Micro-LEDs, at the sub-millimeter or even micrometer scale, are self-emissive devices, just like organic light-emitting diodes (OLEDs). Like OLEDs, they offer a range of advantages, including high brightness, ultra-low latency, and ultra-wide viewing angles. Furthermore, because inorganic LEDs emit light based on more stable and lower-resistance metal semiconductors, they offer advantages over organic LEDs, such as lower power consumption, better resistance to high and low temperatures, and longer lifespan. When used as backlights, micro-LEDs can achieve more precise dynamic backlighting effects, effectively improving screen brightness and contrast while eliminating glare caused by traditional dynamic backlighting between bright and dark areas, thus optimizing the visual experience.

The hardware circuit may include conventional very-large-scale integrated circuits (VLSI) or gate arrays, as well as existing semiconductors or other discrete components such as logic chips and transistors; the hardware circuit may also include field-programmable gate arrays, programmable array logic, programmable logic devices, etc. Furthermore, those skilled in the art will understand that the above structure does not constitute a limitation on the display device provided in the embodiments of this disclosure.
