[0081] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. It should be noted that the sizes and shapes of the figures in the drawings do not reflect the actual proportions, and the purpose is only to illustrate the contents of the present invention. And the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0082] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by persons of ordinary skill in the field to which the invention belongs. The words "first", "second" and similar terms used in the specification and claims of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Inside", "outside", "upper", "lower" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0083] As used herein, "about" or "approximately the same" is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "approximately the same" can mean that the difference relative to the stated value is within one or more standard deviations, or within ±30%, 20%, 10%, 5%.

[0084] In the accompanying drawings, the thickness of layers, films, panels, regions, etc. are exaggerated for clarity. Exemplary embodiments are described herein with reference to cross-sectional views that are schematic representations of idealized embodiments. As such, deviations from the shapes of the figures are to be expected as a result of, for example, manufacturing techniques and / or tolerances. Thus, the embodiments described herein should not be construed as limited to the specific shapes of the regions as shown herein, but rather include deviations in shape that result from, for example, manufacturing. For example, a region illustrated or described as flat may typically have rough and / or nonlinear features. Furthermore, sharp corners illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.

[0085] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components.

[0086] The liquid crystal cell is the core of an LCD, and its display quality is primarily influenced by it. Key parameters of an LCD include transmittance, contrast, viewing angle, response time, and drive voltage. Response time represents the time required for the external electric field torque, driven by the pixel voltage, to overcome the resistance created by the elastic modulus and viscosity of the liquid crystal molecules, switching them between the bright (white) and dark (black) states. The longer the response time, the more noticeable the image smearing phenomenon is.

[0087] In previous designs, OD overdrive technology was used to address the issue of long response times. However, the response time of liquid crystal molecules is easily affected by temperature, especially for negative liquid crystal molecules. When the ambient temperature of the liquid crystal molecules changes, the response time also changes. The OD setting parameters at this time cannot correspond to the response time after the temperature change, which can cause problems with the screen display. When the temperature drops, the deflection speed of the liquid crystal molecules slows down, and the original OD function cannot be met, resulting in poor screen tailing. When the temperature rises, the deflection speed of the liquid crystal molecules becomes faster, and the original OD function is excessive, resulting in poor screen inversion and tailing.

[0088] In view of this, an embodiment of the present disclosure provides a display panel, as shown in FIG1 , having a display area AA and a plurality of fan-shaped wiring areas F located on one side of the display area AA, wherein the display panel includes:

[0089] A plurality of gate lines 1 extending along a first direction X and located in the display area AA;

[0090] A plurality of data lines 2 extending along the second direction Y, intersecting the gate lines 1, and located in the display area AA;

[0091] Multiple routing groups Z, at least one routing group Z among the multiple routing groups Z is located in at least one fan-shaped routing area F among the multiple fan-shaped routing areas F. Specifically, the fan-shaped routing areas F can correspond to the routing groups Z one by one, and one fan-shaped routing area F is provided with one routing group Z; at least part of the routing groups Z is electrically connected to the data line 2, the routing group includes multiple routing lines, and the routing lines in the routing group are electrically connected to the data line for providing data signals to the data line;

[0092] At least one temperature sensor 3 is located on the same side of the display area AA as the fan-shaped wiring area F, and at least part of the temperature sensor 3 is located in the area between adjacent fan-shaped wiring areas F;

[0093] The temperature sensor 3 is configured to detect the ambient temperature so that the display panel applies a voltage to the data line 2 based on the temperature detected by the temperature sensor 3. Specifically, when the temperature detected by the temperature sensor 3 is within a first threshold (which may be a temperature range below room temperature), the voltage applied to the data line 2 is greater than the voltage applied at the same grayscale at room temperature, thereby accelerating the deflection speed of the liquid crystal and avoiding smearing. Furthermore, when the temperature detected by the temperature sensor 3 is within a second threshold (which may be a temperature range above room temperature), the voltage applied to the data line 2 is less than the voltage applied at the same grayscale at room temperature, thereby slowing the deflection speed of the liquid crystal and avoiding reverse smearing. Specifically, a table of correspondences between temperature and grayscale can be stored in the display device. For example, a first storage table corresponding to the first threshold, a second storage table corresponding to the second threshold, and a third storage table corresponding to room temperature can be stored. When the temperature is detected to be within the first threshold, a voltage is applied to the data line 2 according to the first storage table; when the temperature is detected to be within the second threshold, a voltage is applied to the data line 2 according to the second storage table; and when the temperature is detected to be within the room temperature range, a voltage is applied to the data line 2 according to the third storage table. Specifically, the first threshold value may correspond to a temperature below room temperature, and the second threshold value may correspond to a temperature above room temperature. Specifically, in a possible implementation, the first storage table may be an OD parameter table set according to a low temperature, the second storage table may be an OD parameter table set according to a high temperature, and the third storage table may be an OD parameter table corresponding to room temperature. The OD parameter table includes overdrive grayscale values ​​confirmed corresponding to the previous frame grayscale and the current frame grayscale. For example, the previous frame grayscale includes 0, 8, 16, 24, 32, 40, 48….240, 248, 255 grayscales (each interval is 7 grayscales, of course, other interval grayscales can also be set, which is not limited here); the current frame grayscale includes 0, 8, 16, 24, 32, 40, 48….240, 248, 255 grayscales (each interval is 7 grayscales, of course, other interval grayscales can also be set, which is not limited here); For example, if the grayscale of the previous frame is 32 grayscales and the grayscale of the current frame is 64 grayscales, the OD grayscale table corresponds to 84 grayscales (the grayscale of the current frame is greater than the grayscale of the previous frame, and the OD grayscale may be greater than the grayscale of the current frame); for example, if the grayscale of the previous frame is 168 grayscales and the grayscale of the current frame is 40 grayscales, the OD grayscale table corresponds to 38 grayscales (the grayscale of the current frame is less than the grayscale of the previous frame, and the OD grayscale may be less than the grayscale of the current frame); the grayscale of the current frame is equal to the grayscale of the previous frame, and the OD grayscale may be equal to the grayscale of the current frame.It should be noted that in this case, multiple OD parameter tables can be stored, and different OD parameter tables can be called according to different temperatures or temperature ranges to provide data signals to the data lines of the display area. Of course, only two OD parameter tables can be stored, namely two versions of parameter tables corresponding to high temperature (for example, 50~60℃) and low temperature (-40~-30℃). The parameter tables corresponding to other temperatures are calculated and generated based on the detected temperature based on the high temperature and low temperature parameter tables. This can reduce the storage of storage tables.

[0094] In the embodiment of the present disclosure, a temperature sensor 3 is provided on the side of the fan-shaped wiring area F of the display panel. The display panel loads a voltage on the data line 2 according to the temperature detected by the temperature sensor 3, so that when the temperature detected by the temperature sensor 3 is low or high, the OD table corresponding to different temperatures is called to ensure that the liquid crystal molecules maintain the same (normal) deflection speed at different temperatures, so that the display panel can adjust the OD parameters in real time according to the change of the ambient temperature to ensure the normal display of the picture, thereby improving the problem of OD function failure caused by temperature change and ensuring the working performance of the display panel at different temperatures; in addition, compared with the temperature sensor 3 provided on other sides of the display panel, in the embodiment of the present disclosure, the temperature sensor 3 is located on the side of the fan-shaped wiring area F of the display panel, which can avoid the signal detected by the temperature sensor 3 itself being relatively high. The signal strength of the calibrated signal is weak. If it is set in an area far away from the side of the circuit board bound to the fan-shaped routing area F, the longer routing will affect the calibrated signal strength, resulting in an inaccurate signal. Moreover, the temperature sensor 3 is located on the side of the fan-shaped routing area F of the display panel, which has little effect on the internal wiring of the display panel, and the wiring space between the fan-out routing areas of the display panel is large. When a common routing is set in the area between the fan-out routings, the wiring of the common routing can be adjusted to set the temperature sensor. Since the wiring area of ​​the common routing is larger than that of other display signal lines, the sensor is given a new function by adjusting the common routing without having a major impact on the common routing signal and the display effect. That is, the display panel can be given a new function while ensuring normal display, thereby improving the display quality.

[0095] In a possible embodiment, referring to Figures 1 and 2A-2E, Figure 2A is an enlarged schematic diagram of the temperature sensor 3 in Figure 1, Figure 2B is an equivalent circuit diagram of Figure 2A, Figure 2C is a single-film schematic diagram of the first electrode portion in Figure 2A, Figure 2D is a single-film schematic diagram of the active portion in Figure 2A, and Figure 2E is a single-film schematic diagram of the second electrode portion in Figure 2A. The display panel includes an array substrate P1 and an opposing substrate P2 that are relatively arranged, and the temperature sensor 3 is located on the array substrate P1; the array substrate P1 has a first substrate 10, and the temperature sensor 3 includes a first electrode portion 31, an active portion 32 located on a side of the first electrode portion 31 away from the first substrate 10, and a second electrode portion 33 located on the active portion 32 away from the first electrode portion 31; the orthographic projection of the first electrode portion 31 on the first substrate 10 covers the orthographic projection of the active portion 32 on the first substrate 10, and the orthographic projection of the active portion 32 on the first substrate 10 covers at least part of the orthographic projection of the second electrode portion 33 on the first substrate 10. Specifically, a control signal may be applied to the first wiring 41 electrically connected to the first electrode portion 31 , and a signal corresponding to the temperature may be obtained by measuring a signal between the second wiring 42 and the third wiring 43 electrically connected to the second electrode portion 33 .

[0096] Specifically, as shown in FIG. 1 , on the side where the fan-shaped wiring area F is located, the temperature sensor 3 can be specifically arranged in the area between the outer edge of the display area AA and the outer edge of the opposite substrate P2 .

[0097] In a possible embodiment, referring to Figures 1 and 2A-2E, the second electrode portion 33 includes: a first sub-portion 331 and a second sub-portion 332 arranged opposite to each other, wherein the first sub-portion 331 includes: a first main portion 3311 extending along the first direction, and a plurality of first branches 3312 extending from the first main portion 3311 along the second direction Y; the second sub-portion 332 includes: a second main portion 3321 extending along the first direction X, and a plurality of second branches 3322 extending from the second main portion 3321 along the second direction Y, and the first branches 3312 and the second branches 3322 are arranged crosswise.

[0098] Specifically, as shown in Figures 2A and 2B, the temperature sensor 3 can be a transistor, wherein the first electrode portion 31 can serve as a control electrode TG, the first sub-portion 331 can serve as a first electrode TD of the transistor, and the second sub-portion 332 can serve as a second electrode TS of the transistor. The temperature sensor 3 is turned on or off by the first electrode portion 31, and the current signal between the first sub-portion 331 and the second sub-portion 332 can be measured to obtain the relevant signal detected by the temperature sensor 3. Specifically, the temperature sensor 3 can be made of a gate layer metal to form the first electrode portion 31, a semiconductor active layer to form the active portion 32, and a data line layer metal to form the second electrode portion 33, leading to the gate (TG), source (TS), and drain (TD) of the temperature sensor. The channel width-to-length ratio (W / L) of the transistor can be 2500 / 3.9 (can be adjusted according to factors such as the materials used and the design scheme). In order to increase the detection accuracy of the sensor, the width-to-length ratio of the transistor set in the sensor is greater than the transistor set in the display area of ​​the display panel. The transistor set in the display area is used to achieve electrical connection with the gate line, data line and pixel electrode of the display panel. Optionally, in this case, in order to simplify the process, the transistor set in the display area and the transistor structure included in the temperature sensor or the light sensor are prepared by the same process, that is, the transistor in the display area and the sensor between the fan-shaped routing area are prepared by the same layer and material.

At least one temperature sensor 3 includes two first electrode portions 31 arranged along the first direction X, two active portions 32 arranged along the first direction X, and two second electrode portions 33 arranged along the first direction X; the two first electrode portions 31 are spaced apart and independent of each other; the two active portions 32 are spaced apart and independent of each other; the two second electrode portions 33 share a first main portion 3331, and the second main portions 3321 of the two second electrode portions 33 are spaced apart and independent of each other. In the embodiment of the present disclosure, the temperature sensor 3 adopts a dual-transistor structure, and the structural composition and process parameters of the two transistors can be completely consistent; the two transistors use the same first main part 3331, and the first electrode part 31 and the second main part 3321 are used independently. In the specific implementation, combined with Figure 3B, only one of the transistors can be set to be in normal working state, and its three-terminal electrodes are set to appropriate voltages according to the situation (for example: TG1=-8V, TS=0V, TD1=15V), and the other transistor does not work, and the voltage condition is set to TG2=TD2=TS to ensure that the three-terminal potentials are the same to avoid characteristic drift. The two transistors periodically switch the working state according to the usage time to avoid characteristic drift caused by long-term operation, thereby increasing the service life of the temperature sensor and improving the detection accuracy of the temperature sensor.

[0100] Specifically, referring to FIG3F , the transfer curve of the temperature sensor changes with temperature. When the ambient temperature rises from -20°C to 60°C, the increase in the on-state current Ion is not obvious, while the increase in the off-state current Ioff is obvious. The off-state current Ioff is more sensitive to temperature changes, but the off-state current Ioff is small in value, difficult to detect, and easily affected by noise. The off-state current Ioff or the on-state current Ion can be selected as the detection signal of the temperature sensor according to the specific situation.

[0101] In one possible embodiment, referring to FIG. 1 , FIG. 3A to FIG. 3E , and FIG. 4 , the display panel further includes: a plurality of sensor leads 4; the plurality of sensor leads 4 include: a first trace 41 having one end electrically connected to the first electrode portion 31 and extending away from the display area AA; a second trace 42 having one end electrically connected to the first main portion 3311 and extending away from the display area AA; and a third trace 43 having one end electrically connected to the second main portion 3321 and extending away from the display area AA.

Specifically, floating pins corresponding to the floating gold fingers of the flexible circuit board are provided on the display panel, and the floating pins and floating gold fingers are electrically connected to each other to transmit signals. This allows the existing flexible circuit board to be compatible with the sensor signal transmission of this embodiment, avoiding the need for configuring new flexible circuit boards or gold fingers, and thus avoiding increasing the production cost of the display panel. When the display panel includes multiple flexible circuit boards, the floating gold fingers of some of the flexible circuit boards can be electrically connected to the floating pins of the display panel to transmit electrical signals.

[0106] In a possible implementation, referring to FIG. 3A to FIG. 3E and FIG. 5 , where FIG. 5 is a cross-sectional view taken along the dashed line EF in FIG. 3A , the second routing line 42 includes a first sub-routing portion 421 and a second sub-routing portion 422 ; the third routing line 43 includes a third sub-routing portion 431 and a fourth sub-routing portion 432 ;

The first sub-routing portion 421 and the second sub-routing portion 422 are connected to each other through the first adapter portion 51. The orthographic projection of the second adapter portion 52 on the first substrate 10 covers the orthographic projection of the third sub-routing portion 431 and the orthographic projection of the fourth sub-routing portion 432 on the first substrate 10. The third sub-routing portion 431 and the fourth sub-routing portion 432 are connected to each other through the second adapter portion 52.

[0109] In the embodiment of the present disclosure, the second routing 42 includes: a first sub-routing portion 421 and a second sub-routing portion 422; the third routing 43 includes: a third sub-routing portion 431 and a fourth sub-routing portion 432.

That is, the sensor lead 4 is switched to a higher layer when it is close to the circuit board side, that is, the sensor lead 4 and the common routing can be placed on the same layer, and both are set on the layer where the gate line is located, which can facilitate the introduction of the sensor lead to the position of the pad.

[0110] Specifically, referring to FIG. 3A to FIG. 3E and FIG. 5 , the array substrate may further include a first hole K1 and a second via hole K2, wherein the first via hole K1 includes a first group of holes K11 and a second group of holes K12 arranged along the first direction X, wherein the first group of holes K11 includes a plurality of first sub-via holes K110 arranged along the second direction Y, and the second group of holes K12 includes a plurality of second sub-via holes K120 arranged along the second direction Y; the first adapter portion 51 is connected to the first sub-routing portion 421 through the first sub-via hole K110, and the first adapter portion 51 is connected to the second sub-routing portion 422 through the second sub-via hole K120, thereby realizing the first The first sub-routing portion 421 and the second sub-routing portion 422 are electrically connected; the second via K2 includes a third group of holes K21 and a fourth group of holes K22 arranged along the first direction X, wherein the third group of holes K21 includes a plurality of third sub-vias K210 arranged along the second direction Y, and the fourth group of holes K22 includes a plurality of fourth sub-vias K220 arranged along the second direction Y; the second adapter portion 52 is electrically connected to the third sub-routing portion 431 through the third sub-via K210, and the second adapter portion 52 is electrically connected to the fourth sub-routing portion 432 through the fourth sub-via K220, thereby realizing the electrical connection between the third sub-routing portion 431 and the fourth sub-routing portion 432. In the embodiment of the present disclosure, the first hole K1 includes multiple first sub-vias K110 and multiple second sub-vias K120, which can achieve good conductivity between the first transfer portion 51 and the first sub-routing portion 421, and the second via K2 includes multiple third sub-vias K210 and multiple fourth sub-vias K220, which can achieve good conductivity between the second transfer portion 52 and the fourth sub-routing portion 432.

[0111] In one possible embodiment, as shown in Figures 3A-3E and 5, the first and third sub-routing portions 421, 431, and second electrode portion 33 are constructed from the same layer and material; the second and fourth sub-routing portions 422, 432, and first electrode portion 31 are constructed from the same layer and material; and the first routing portion 41 is constructed from the same layer and material as first electrode portion 31. This improves the OD function failure caused by temperature changes, ensuring the display panel's performance at different temperatures without increasing the number of manufacturing steps required for the display panel.

[0112] In one possible embodiment, as shown in Figures 3A-3E and 5, data line 2 is located on the side of gate line 1 facing away from first substrate 10; the display panel includes: a pixel electrode and / or a common electrode located on the side of data line 2 facing away from gate line 1; a first electrode portion 31 and the same layer and material as gate line 1; a second electrode portion 33 and the same layer and material as data line 2; and a first transition portion 51 and a second transition portion 52 and the same layer and material as the pixel electrode layer or the common electrode. This improves the problem of OD function failure due to temperature changes, ensures the performance of the display panel at different temperatures, and does not increase the number of manufacturing steps for the display panel.

[0113] Specifically, as shown in Figure 5, there may be a gate insulating layer GI between the gate line 1 and the data line 2, a passivation layer PVX may be provided between the data line 2 and the pixel electrode and / or the common electrode, the first sub-via K110 and the third sub-via K210 may penetrate the passivation layer PVX, and the second sub-via K120 and the fourth sub-via K220 may penetrate the passivation layer PVX and the gate insulating layer GI.

[0114] In one possible embodiment, referring to FIG. 6 , which is an enlarged schematic diagram of the dotted coil S2 in FIG. 4 , at least one of the second sub-routing portion 422 and the fourth sub-routing portion 432 has a plurality of hollow areas P0. In the disclosed embodiment, since the second sub-routing portion 422 and the fourth sub-routing portion 432 are located outside the display area AA, which is covered by the frame sealant, the presence of the plurality of hollow areas P0 in the second sub-routing portion 422 and the fourth sub-routing portion 432 allows the ultraviolet light used to cure the frame sealant to pass through the second sub-routing portion 422 and the fourth sub-routing portion 432, thereby avoiding the problem of the frame sealant not being properly cured by UV.

[0115] In one possible embodiment, as shown in FIG6 , the common trace 6 has a first hollow portion P1, and the common trace 6 is at least partially disposed between adjacent fan-shaped trace areas F. The orthographic projection of the temperature sensor 3 on the first substrate 10 is located within the orthographic projection of the first hollow portion P1 on the first substrate 10. In the disclosed embodiment, placing the temperature sensor 3 at the location of the first hollow portion P1 of the common trace 6 allows for a compact arrangement of the common trace 6 and the temperature sensor 3, which improves metal lithography uniformity at this location.

[0116] In one possible embodiment, as shown in FIG6 , the common trace 6 further has a plurality of second hollow portions P2, with the area of ​​the first hollow portion P1 being larger than the area of ​​the second hollow portion P2. The common trace 6 is formed from the same layer and material as the first electrode portion 31. In the disclosed embodiment, since the common trace 6 is located outside the display area AA, which is covered by the frame sealant, the presence of the plurality of second hollow portions P2 allows the UV light used to cure the frame sealant to pass through the common trace 6, thereby preventing the frame sealant from properly curing under UV light.

[0117] In a possible embodiment, referring to FIG7 , FIG7 may be an enlarged schematic diagram of the dotted circle S1 in FIG4 , wherein the routing group Z includes a plurality of leads Z1; the spacing d1 between adjacent sensor leads 4 is 1.5 to 5 times the spacing d2 between adjacent leads Z1. Since the fan-shaped routing area is provided with a large number of leads, in order to reduce the design of the frame, the lead wiring density will be set higher, and the line spacing will be made thinner, for example, 3 μm to 8 μm, while ensuring process stability; the line width d3 of the sensor lead 4 is 5 to 10 times the line width d4 of the lead Z1. Specifically, the spacing d2 between adjacent leads Z1 in the routing group Z can be 3μm to 8μm, specifically, for example, 3μm, 4μm, 5μm, 5.3μm, 6μm, 7μm, 8μm; the spacing d1 of the sensor leads 4 can be equal to the spacing of the signal lines of the gate drive circuit (such as the clock signal line). The signal lines of the gate drive circuit extend longer in the non-display area, and for example, the clock signal line transmits an AC signal, and there will be coupling between the signal lines. Under the premise of considering reducing the non-display frame, the distance cannot be too close. Since the sensor leads need to detect or feedback signals, etc., to avoid the coupling between the signal lines, they can be close to the gate drive circuit. The spacing between the signal lines is consistent. Specifically, the spacing d1 of the sensor lead 4 can be 10μm to 20μm, and specifically, for example, it can be 10μm, 11μm, 15μm, 16μm, 17μm, 18μm, and 20μm; the line width d3 of the sensor lead 4 can be 40μm to 60μm, and specifically, for example, it can be 40μm, 42μm, 48μm, 50μm, 52μm, 54μm, and 60μm; the line width d4 of the lead Z1 in the routing group Z can be 5μm to 10μm, and specifically, for example, it can be 5μm, 6μm, 6.5μm, 7μm, 7.5μm, 9μm, and 10μm.

[0118] In one possible embodiment, referring to Figures 1 and 3A-3E, the orthographic projection of the active portion 32 on the first substrate 10 is a square. Specifically, the orthographic projection of the active portion 32 on the first substrate 10 is a square, that is, the side length of the active portion 32 along the first direction X is equal to the side length along the second direction Y. In the embodiment of the present disclosure, the orthographic projection of the active portion 32 on the first substrate 10 is a square, which can make the temperature sensor as a whole square and difficult to observe from the outside. Compared to a rectangular temperature sensor, if there is no black matrix to block it, bright stripes may be observed from the outside due to the reflection of the metal layer.

[0119] In one possible embodiment, as shown in Figures 1 and 3A-3E, the orthographic projection of the first electrode portion 31 onto the first substrate 10 may also be a square. Specifically, the orthographic projection of the first electrode portion 31 onto the first substrate 10 is a square, meaning that the length of the side of the first electrode portion 31 along the first direction X is equal to the length of the side along the second direction Y. This allows the temperature sensor to have an overall square shape, making it less visible from the outside. Compared to a rectangular temperature sensor, in which a more obvious bright stripe is visible from the outside, the temperature sensor can be formed.

[0120] In one possible embodiment, as shown in FIG8 , the display panel further includes at least one light sensor 7 . Light sensor 7 and sector trace area F are located on the same side of display area AA, and light sensor 7 is located in an area outside sector trace area F. Light sensor 7 is configured to detect brightness and adjust the brightness of the display panel based on the detected brightness. FIG8 illustrates that light sensor 7 and temperature sensor 3 are respectively disposed between different sector trace areas. Alternatively, both light sensor 7 and temperature sensor 3 can be disposed between adjacent sector trace areas, i.e., both light sensor 7 and temperature sensor 3 are disposed in the area corresponding to temperature sensor 3 in FIG8 , without limitation herein.

[0121] In a possible embodiment, referring to Figures 9A to 9E, Figure 9B is a schematic diagram of a single film layer of the first electrode portion in Figure 9A, Figure 9C is a schematic diagram of a single film layer of the active portion in Figure 9A, Figure 9D is a schematic diagram of a single film layer of the second electrode portion in Figure 9A, and Figure 9E is a schematic diagram of a single film layer of the black matrix layer in Figure 9A. The structure of the light sensor 7 is the same as that of the temperature sensor 3, which can simplify the manufacturing process and make the display panel compatible with temperature detection and light detection. In addition, under the same structure, when temperature detection is required, it can be used as a temperature sensor, and when brightness detection is required, it can be used as a light sensor, that is, the temperature sensor integration is compatible with the light sensor design, and the production of two different functional devices is realized in one process. Optionally, the temperature sensor and the light sensor can be both set at a corresponding position between two adjacent fan-shaped routing areas, or they can be set at different positions between two adjacent fan-shaped routing areas. In this case, both the temperature sensor and the light sensor are set in the display panel. Through a simple preparation process, the panel can be compatible with both functions, thereby improving the display quality and the integration of the display panel.

[0122] Specifically, the structure of the light sensor 7 is identical to that of the temperature sensor 3. The film composition, pattern shapes, and process parameters of the light sensor 7 and the temperature sensor 3 can be completely identical. Of course, in a specific implementation, the film composition, pattern shapes, and patterns of the light sensor 7 and the temperature sensor 3 may differ in some respects. Specifically, for example, as shown in Figures 9A and 9B , the first electrode portions 31 of the two sub-light sensors 71 can be an integrated, interconnected structure.

[0123] In one possible embodiment, as shown in Figures 9A to 9E, the light sensor 7 includes two sub-light sensors 70; the display panel also has a black matrix layer 8, the black matrix layer 8 has a first black matrix opening 81, and one of the sub-light sensors 70 of the light sensor 7 is located in the first black matrix opening 81 on the orthographic projection of the first substrate 10, and the other sub-light sensor 71 is blocked by the black matrix layer 8. In the embodiment of the present disclosure, the light sensor 7 also adopts a dual-transistor structure, and the process parameters of the two transistors are exactly the same as those of the temperature sensor. One of the sub-light sensors 71 is not covered by the black matrix (that is, it is located in the area where the first black matrix opening 81 is located), that is, one sub-light sensor 71 can be illuminated by ambient light, and the other sub-light sensor 71 cannot be illuminated by ambient light, so as to measure the external light intensity by the brightness difference between the two. In this case, the black matrix can be arranged on the opposite substrate opposite to the array substrate, or it can be arranged on one side of the array substrate, which is not limited here.

[0124] In one possible implementation, as shown in FIG9A , the outer contour of the active portion of the sub-light sensor 71 is a square, thereby avoiding the bright stripe problem caused by the reflection of the metal layer in the area not covered by the black matrix.

[0125] Specifically, referring to FIG10A , FIG10A may be an equivalent circuit diagram of FIG9A , where the sub-light sensor 71 is a three-terminal field effect transistor structure, and the three terminals are PS, PG, and PD respectively; the two sub-light sensors 71 use the same PS and PG electrodes, and the PD electrodes are used independently.

[0126] Specifically, see Figure 10B, which shows the characteristics of the light sensor as the light changes. When the ambient light changes from darkness to 5000 nit, the on-state current Ion increases slightly, while the off-state current Ioff increases significantly. The off-state current Ioff is more sensitive to changes in ambient light, but the current value is small and difficult to capture. During normal operation, PG can be set to -8V (the point at which the light sensor is most sensitive to light, which can be adjusted according to the external drive circuit conditions. The point at which the sensor is most sensitive to light under different process conditions may be different), PS can be set to 0V, and PD1 and PD2 can be set to 15V. After the sub-light sensor 71 at the first black matrix opening 81 is illuminated by ambient light, the current value increases compared to the sub-light sensor 71 at the location blocked by the black matrix, and the increase is proportional to the light intensity. The current difference between PD1 and PD2 is taken as the reference value under the ambient light condition to adjust the backlight brightness.

[0127] In a possible implementation, as shown in FIG. 11 , the display panel has a first symmetry axis k1 ; the first symmetry axis k1 passes through the center of at least one temperature sensor 3 .

[0128] In one possible embodiment, as shown in FIG11 , the display panel further includes a first side region B1 opposite to the fan-shaped routing region F, and a second side region B2 and a third side region B3 connecting the side of the fan-shaped routing region F and the first side region B1; the first side region B1, the second side region B2, and the third side region B3 are regions located on one side of the display area AA; and at least one of the first side region B1, the second side region B2, and the third side region B3 is provided with a temperature sensor 3. In the embodiment of the present disclosure, in addition to the temperature sensor 3 provided on the side of the fan-shaped routing region F, the temperature sensor 3 is also provided in the first side region B1, the second side region B2, and the third side region B3, which can effectively improve the detection accuracy, especially for large-size display products, where the temperature at different locations may vary greatly.

[0129] In one possible embodiment, the first electrode portion 31 of at least one of the temperature sensor 3 and the light sensor 7 is configured to be loaded with a square wave signal to turn on the temperature sensor 3 and / or the light sensor 7 at preset intervals. Specifically, the first electrode portion of the temperature sensor 3 and the light sensor 7 is fed with a square wave (AC) signal, i.e., turned on at preset intervals, for example, at intervals of 10 seconds. This prevents the transistor from being constantly on, which could cause the temperature sensor 3 and the light sensor 7 to drift. The square wave signal is, for example, a PWM signal.

[0130] Specifically, the display area AA may be provided with a pixel circuit, which may include pixel circuit transistors, temperature sensors 3 and light sensor 7 film layers, which may be manufactured in the same layer and process as the corresponding film layers of the pixel circuit transistors.

[0131] Based on the same inventive concept, an embodiment of the present disclosure further provides a display device, which includes a display panel provided by the embodiment of the present disclosure.

[0132] In one possible embodiment, referring to Figures 1, 8, and 11, the display device further includes a first circuit board C1 electrically connected to the display panel; the first circuit board C1 is provided with a first processor D1 to process the temperature signal detected by the temperature sensor 3 to generate a first signal. Specifically, the first circuit board C1 may be a printed circuit board (PCB), and the first processor D1 may be an operational amplifier (OP) to amplify, add, subtract, and perform differential operations on the signals detected by the temperature sensor 3 or the light sensor 7. For example, the first processor D1 may perform differential operations on the signals received by the two sub-sensors 71 in the light sensor 7 to obtain the detected external light signal after eliminating interference from other factors.

[0133] In a possible implementation, referring to FIG. 1 , FIG. 8 and FIG. 11 , the display device further includes a second circuit board C2 located on a side of the first circuit board C1 away from the display panel and electrically connected to the first circuit board C1 ;

[0134] The second circuit board C2 includes: a second processor D2, the second processor D2 is configured to process the first signal to form a second signal; the display device also includes: a third processor D3, wherein the third memory D3 stores at least a first storage table corresponding to room temperature, a second storage table corresponding to the first threshold, and a third storage table corresponding to the second threshold; the third processor D3 is configured to call the first storage table, the second storage table or the third storage table according to the second signal to load a voltage to the data line according to the grayscale of the first storage table, the second storage table or the third storage table.

[0135] Specifically, the second circuit board C2 can be a logic board. The second processor D2 can be a microcontroller unit (MCU), and the third processor D3 can be a logic processor TCON. The temperature sensor 3 converts the captured temperature signal into a specific target value via the MCU and sends it to the TCON via the I2C line to call the corresponding OD table. The signal acquisition method is in-phase proportional amplification.

[0136] Specifically, referring to FIG. 1 , FIG. 8 and FIG. 11 , one end of the first processor D1 may be electrically connected to the temperature sensor 3 , and the other end thereof may be electrically connected to the second processor D2 , and the second processor D2 may be electrically connected to the third processor D3 .

[0137] In one possible embodiment, as shown in FIG8 , the display device includes a backlight source located on the backlight side of the display panel, and a fourth processor D4; the fourth processor D4 is configured to adjust the brightness of the backlight source based on the signal detected by the light sensor. The fourth processor D4 may be an LED driver. Specifically, the fourth processor D4 may be electrically connected to the second processor D2 and to the backlight interface of the display panel. The light sensor transmits the received light signal to the MCU processing unit via the OP, and the MCU sends the processed Target signal to the BLU to adjust the backlight brightness.

[0138] The display panel of the present disclosure differs from conventional display panels with OD functions in that the integrated temperature sensor design of the display panel, combined with OD adjustment, can ensure normal display of the panel under high and low temperature conditions, thereby improving the panel's operational stability. Unlike conventional external temperature sensors, the temperature sensor of the display panel of the present disclosure is integrated within the display panel, without occupying additional space or increasing the panel's volume. The temperature sensor utilizes a bottom-gate thin-film transistor structure, which is compatible with conventional liquid crystal panel manufacturing processes and does not require additional photolithography. The temperature sensor is manufactured along with other structures in the liquid crystal panel, without adding additional production costs. Unlike conventional external temperature sensors, the circuit driving scheme of the integrated temperature sensor design of the display panel of the present disclosure is compatible with existing liquid crystal panel circuit driving schemes with minimal changes. The integrated temperature sensor design of the display panel of the present disclosure is compatible with the integrated light sensor design, meaning that both a temperature sensor and a light sensor can be integrated on the display panel, expanding the panel's functionalities. Without changing the internal wiring of the display panel, the light sensor can be converted to a temperature sensor by simply adjusting the external driving circuit, thereby increasing the display panel's operational flexibility.
