[0028] To clarify the objectives, technical solutions, and advantages of the embodiments of the present invention, the technical solution of these embodiments is described in detail below, in conjunction with the drawings of these embodiments. It should be noted that the dimensions and shapes of the individual graphics in the drawings do not reflect actual proportions but merely serve to schematically illustrate the content of the present invention. Furthermore, identical or similar designations throughout refer to the same or similar components or components with the same or similar functions. Obviously, the described embodiments represent only a subset of the embodiments of the present invention, not all of them.Based on the described embodiments of the present invention, all other embodiments which the average person skilled in the art obtains without creative effort may fall within the scope of protection of the present invention.

[0029] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons with general knowledge in the field of the present invention. Terms such as "first," "second," and similar terms used in the description and claims of the present invention do not express any order, number, or importance, but serve only to distinguish different components. Terms such as "comprise" or "include" mean that the elements or objects preceding such term include the elements or objects listed after that term, as well as their equivalents, and do not exclude other elements or objects. Expressions such as "within," "outside," "above," "below," etc., serve only to indicate relative positional relationships.Furthermore, if the absolute position of the described object changes, the relative position relationship can change accordingly.

[0030] As used here, “approximately” or “essentially the same” encompasses the stated value and means that the value lies within an acceptable range of deviations for the stated value, as determined by a person skilled in the art, taking into account the measurements taken and the errors associated with measuring a specific quantity (i.e., the limitations of the measuring system). For example, “essentially the same” may mean that the deviation from the stated value is within one or more standard deviations, or within the range of ±30%, 20%, 10%, or 5%.

[0031] For clarity, the thickness of layers, membranes, panels, areas, etc., is shown enlarged in the drawings. This document describes the manufacturing process using sectional drawings, which serve as schematic representations of idealized designs. Therefore, deviations from the shapes shown in the drawings are to be expected due to factors such as manufacturing techniques and / or tolerances. Consequently, the designs described here should not be interpreted as limited to the specific shapes of the areas shown, but also include shape variations caused by the manufacturing process. For example, an area depicted or described as flat may typically exhibit rough and / or non-linear properties. Furthermore, the sharp corners shown may actually be rounded.Therefore, the areas in the drawings are essentially schematic and their shapes are not intended to represent the exact shape of the areas or to limit the scope of the claims.

[0032] In order to keep the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components is omitted.

[0033] The liquid crystal cell is the core of a liquid crystal display, and the display effects are primarily influenced by the liquid crystal cell. Key parameters of the liquid crystal cell include the transmission rate, contrast, viewing angle, response time, and drive voltage, among others. The response time characterizes the time required by the liquid crystal cell to switch the liquid crystal molecules between the bright state (white state) and the dark state (black state). This occurs when the moment of the external electric field, driven by the pixel voltage, overcomes the resistances created by the elasticity coefficient, viscosity, and other properties of the liquid crystal molecules. The longer the response time, the easier it is for the human eye to observe image lag phenomena.

[0034] In earlier designs, OD overdrive technology was used to solve the problem of excessively long response times. However, the response time of the liquid crystal molecules is temperature-sensitive, especially for negatively charged liquid crystal molecules. When the ambient temperature of the liquid crystal molecules changes, the response time also changes. In this case, the OD setting parameters no longer correspond to the response time after the temperature change, leading to image display problems. When the temperature decreases, the rotational speed of the liquid crystal molecules slows down, and the original OD function cannot meet the requirements, resulting in image trailing. When the temperature increases, the rotational speed of the liquid crystal molecules speeds up, and the original OD function becomes excessive, leading to inverted color trailing in the image.

[0035] For this reason, the embodiments described in this disclosure provide a display panel. As in Fig. As shown in Figure 1, the display panel has a display area AA and several fan-shaped conductor track areas F on one side of the display area AA, wherein the display panel comprises the following: several gate lines 1 extending in a first direction X and located in the display area AA; several data lines 2 extending in a second direction Y, crossing the gate lines 1 and located in the display area AA; Several conductor groups Z, wherein at least one conductor group Z of the several conductor groups Z is located in at least one fan-shaped conductor area F of the fan-shaped conductor areas F. In particular, the fan-shaped conductor areas F and the conductor groups Z can be assigned one-to-one, wherein each fan-shaped conductor area F is provided with a conductor group Z, and wherein at least a portion of the conductor groups Z are electrically connected to the data lines 2. The conductor group comprises a plurality of conductors, and the conductors in the conductor group are electrically connected to the data lines and serve to supply the data signals to the data lines. at least one temperature sensor 3 located on the same side of the display area AA as the fan-shaped conductor track areas F, wherein at least part of the temperature sensor 3 is located in an area between adjacent fan-shaped conductor track areas F.

[0036] Temperature sensor 3 is configured to measure the ambient temperature, so that the display panel applies voltage to data lines 2 based on the temperature measured by temperature sensor 3. Specifically, if the temperature measured by temperature sensor 3 is within a first threshold (this may be a temperature range below room temperature), the voltage applied to data lines 2 can be higher than the voltage applied at room temperature for the same grayscale level, in order to accelerate the rotational speed of the liquid crystals and avoid image lag.If the measured temperature is within a second threshold (this can be a temperature range above room temperature), the voltage applied to data lines 2 can be lower than the voltage applied at room temperature for the same grayscale level. This slows the rotational speed of the liquid crystals and avoids the inverse image lag problem. Specifically, a table mapping temperature and grayscale levels can be stored in a display device. For example, a first memory table corresponding to the first threshold, a second memory table corresponding to the second threshold, and a third memory table corresponding to room temperature can be stored. If the measured temperature is within the first threshold, the voltage is applied to data lines 2 based on the first memory table.If the measured temperature is within the second threshold, voltage is applied to data lines 2 based on the second memory table. If the measured temperature is within the range of room temperature, voltage is applied to data lines 2 based on the third memory table. Specifically, the first threshold can correspond to a temperature below room temperature, and the second threshold to a temperature above room temperature. In one possible embodiment, the first memory table can be an OD parameter table configured for low temperatures, the second memory table can be an OD parameter table configured for high temperatures, and the third memory table can be an OD parameter table corresponding to room temperature.The OD parameter table contains the confirmation values ​​for the overdrive grayscale, which are determined based on the grayscale of the previous image frame and the grayscale of the current image frame. For example, the grayscale of the previous image frame includes the grayscale levels 0, 8, 16, 24, 32, 40, 48... 240, 248, 255 (with a spacing of 7 grayscale levels, although a different spacing can be chosen; this is not limited here). The grayscale of the current image frame includes the grayscale levels 0, 8, 16, 24, 32, 40, 48... 240, 248, 255 (with a spacing of 7 grayscale levels, although a different spacing can be chosen; this is not limited here).For example, if the grayscale level of the previous image frame is 32 and the grayscale level of the current image frame is 64, the OD grayscale table corresponds to 84 (if the grayscale level of the current image frame is higher than the grayscale level of the previous image frame, the OD grayscale level can be higher than the grayscale level of the current image frame). For example, if the grayscale level of the previous image frame is 168 and the grayscale level of the current image frame is 40, the OD grayscale table corresponds to 38 (if the grayscale level of the current image frame is lower than the grayscale level of the previous image frame, the OD grayscale level can be lower than the grayscale level of the current image frame). If the grayscale level of the current image frame is the same as the grayscale level of the previous image frame, the OD grayscale level can be the same as the grayscale level of the current image frame.It should be noted that in this case, multiple OD parameter tables can be stored, and the different OD parameter tables are called up based on the different temperatures or temperature ranges to supply the data signals to the data lines of the display area. Of course, it is also possible to store only two OD parameter tables: those corresponding to high temperatures (e.g., 50–60°C) and low temperatures (-40–30°C). The parameters for other temperatures can be calculated based on the measured temperature and the high- and low-temperature tables, thus reducing the memory required for the stored tables.

[0037] In the embodiments described in this disclosure, the temperature sensor 3 is located on the side of the display panel where the fan-shaped conductor track area F is situated. The display panel applies voltage to the data lines 2 based on the temperature measured by the temperature sensor 3. When the temperature measured by the temperature sensor 3 is low or high, the corresponding OD table for the different temperatures is called up to ensure that the liquid crystal molecules maintain the same (normal) rotational angular velocity at different temperatures. This allows the display panel to adjust the OD parameters in real time based on changes in the ambient temperature to ensure normal image display and to mitigate the problem of OD function failures due to temperature changes.This ensures the display panel's performance across varying temperatures. Additionally, compared to other sides of the display panel where the temperature sensor could be installed, temperature sensor 3 is located on the side of the display panel where the fan-shaped conductor area F is situated. This prevents the signal measured by temperature sensor 3 from being weak. Furthermore, if the temperature sensor were located far from the circuit board connected to the fan-shaped conductor area, the long conductor path could affect the strength of the calibrated signal and prevent accurate signal detection. Moreover, placing temperature sensor 3 on the side of the fan-shaped conductor area F of the display panel has minimal impact on the display panel's internal wiring.Since the wiring space between the fan-shaped trace areas of the display panel is relatively large, the common trace can be adjusted to accommodate the temperature sensor if a common trace is placed in the area between the fan-shaped trace areas. Because the trace area of ​​the common trace is larger than that of other display signal lines, adjusting the common trace to accommodate the sensor allows the display panel to gain a new function without significantly affecting the common trace signals or impacting the display performance. In other words, the display panel can maintain normal display operation while simultaneously gaining a new function that improves display quality.

[0038] In one possible embodiment, see Fig. 1, Fig. 2A to Fig. 2E, where Fig. 2A an enlarged view of a temperature sensor 3 in Fig. 1 is, Fig. 2B the equivalent circuit diagram of Fig. 2A is, Fig. 2C a representation of the monomembrane of the first electrode section in Fig. 2A is, Fig. 2D representation of the monomembrane of the active section in Fig. 2A is and Fig. 2E a representation of the monomembrane of the second electrode section in Fig. 2A is. The display panel comprises an array base plate P1 and a counter base plate P2, which are arranged opposite each other. The temperature sensor 3 is located on the array base plate P1. The array base plate P1 has a first substrate 10. The temperature sensor 3 comprises a first electrode section 31, an active section 32 on the side of the first electrode section 31 that is located away from the first substrate 10, and a second electrode section 33 on the side of the active section 32 facing away from the first electrode section 31. An orthogonal projection of the first electrode section 31 on the first substrate 10 covers an orthogonal projection of the active section 32 on the first substrate 10, and an orthogonal projection of the active section 32 on the first substrate 10 covers at least part of an orthogonal projection of the second electrode section 33 on the first substrate 10.In particular, a control signal can be applied to a first conductor track 41 which is electrically connected to the first electrode section 31, whereby by measuring the signal between a second conductor track 42 and a third conductor track 43 which are electrically connected to the second electrode section 33, a signal corresponding to the temperature can be obtained.

[0039] In particular see Fig. 1. On the side of the fan-shaped conductor track area F, 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 counter base plate P2.

[0040] In one possible embodiment, see Fig. 1, Fig. 2A to Fig. In 2E, the second electrode section 33 comprises a first section 331 and a second section 332, which are arranged opposite each other. The first section 331 comprises a first main section 3311, extending in a first direction, and several first branch sections 3312, extending from the first main section 3311 in a second direction Y. The second section 332 comprises a second main section 3321, extending in the first direction X, and several second branch sections 3322, extending from the second main section 3321 in the second direction Y. The first branch sections 3312 and the second branch sections 3322 intersect.

[0041] In particular see Fig. 2A and Fig. 2B, the temperature sensor 3 can be a transistor. The first electrode section 31 can serve as the control terminal TG, the first section 331 can serve as the first terminal TD of the transistor, and the second section 332 can serve as the second terminal TS of the transistor. By controlling the switching on or off of the temperature sensor 3 by the first electrode section 31 and measuring the current signal between the first section 331 and the second section 332, a signal can be obtained from the temperature sensor 3. In particular, the temperature sensor 3 can be fabricated by using the gate layer metal for the first electrode section 31, the active semiconductor layer for the active section 32, and the data line layer metal for the second electrode section 33 to fabricate the gate (TG), source (TS), and drain (TD) of the temperature sensor. The channel width to channel length ratio (W / L) of the transistor can be 2500 / 3.The number of transistors in the sensor area is 9 (this can be adjusted depending on the materials used, design plans, and other factors). To increase the sensor's detection accuracy, the width-to-length ratio of the sensor's transistor is greater than the width-to-length ratio of the transistor in the display panel's display area. The display area transistor is used to make electrical connections with the gate lines, data lines, and pixel electrodes of the display panel. Optionally, to simplify the manufacturing process, the display area transistor and the temperature or light sensor transistor can be manufactured using the same process; that is, the display area transistor and the sensor are located on the same layer and made of the same material between the fan-shaped conductor areas.

[0042] In one possible embodiment, see Fig. 1, Fig. 3A to Fig. 3E, where Fig. 3A another enlarged view of the temperature sensor 3 in Fig. 1 is, Fig. 3B the corresponding equivalent circuit diagram of Fig. 3A is, Fig. 3C a representation of the monomembrane of the first electrode section in Fig. 3A is, Fig. 3D representation of the monomembrane of the active section in Fig. 3A is and Fig. 3E a representation of the monomembrane of the second electrode section in Fig. In the embodiment described in this disclosure, at least one temperature sensor 3 comprises two first electrode sections 31 arranged in the first direction X, two active sections 32 arranged in the first direction X, and two second electrode sections 33 arranged in the first direction X. The two first electrode sections 31 are spaced apart and independent. The two active sections 32 are spaced apart and independent. The two second electrode sections 33 share a first main section 3331, and the second main sections 3321 of the two second electrode sections 33 are spaced apart and independent. In the embodiments described in this disclosure, the temperature sensor 3 uses a dual-transistor structure. The structures and manufacturing parameters of the two transistors can be completely identical.The two transistors use the same first main section 3331, and the first electrode section 31 and the second main section 3321 are used independently. In the specific implementation, in conjunction with... Fig. In configuration 3B, only one of the two transistors can be in its normal operating state. Appropriate voltages can be applied to its electrodes at the three ends according to the circumstances (e.g., TG1 = -8V, TS = 0V, TD1 = 15V), while the other transistor is not operating. The voltage conditions are set so that TG2 = TD2 = TS to ensure that all three ends are at the same potential and to prevent the occurrence of characteristic shifts. The two transistors periodically switch their operating state depending on the operating time, thus preventing characteristic shifts due to long-term operation, increasing the lifespan of the temperature sensor, and improving its detection accuracy.

[0043] In particular see Fig. 3F represents the change in the temperature sensor's transfer curve with temperature. When the ambient temperature rises from -20°C to 60°C, the inrush current (Ion) does not increase significantly, while the offrush current (Ioff) increases significantly. The offrush current (Ioff) is more sensitive to temperature changes. However, its value is small, making it difficult to detect and susceptible to interference. Depending on the specific circumstances, either the offrush current (Ioff) or the inrush current (Ion) can be selected as the temperature sensor's detection signal.

[0044] In one possible embodiment, see Fig. 1, Fig. 3A to Fig. 3E and Fig. 4, the display panel further comprises several sensor wires 4. The several sensor wires 4 comprise a first conductor 41, one end of which is electrically connected to the first electrode section 31 and extends in a direction away from the display area AA, a second conductor 42, one end of which is electrically connected to the first main section 3311 and extends in a direction away from the display area AA, and a third conductor 43, one end of which is electrically connected to the second main section 3321 and extends in a direction away from the display area AA.

[0045] The display panel further comprises a pin group G1, which is electrically connected to the conductor group Z, and a flying pin group G2, which is located on the outside of pin group G1.

[0047] In the embodiments of this disclosure, the sensor wire 4 is electrically connected to the flying pin group G2 on the outside of the pin group G1. The flying pins are electrically connected to the flying gold fingers on the flexible printed circuit board. In conventional display panels, some flying gold fingers are arranged on the flexible printed circuit board that is electrically connected to the display panel. The flying gold fingers do not carry a signal. In this case, the flying gold fingers of the flexible printed circuit board can be used to transmit the signal from the installed sensor.By placing flying pins on the display panel that correspond to the flying gold fingers of the flexible printed circuit board (PCB), and establishing an electrical connection between the flying pins and the flying gold fingers to transmit the signal, the existing flexible PCB can be used to make the sensor signal transmission compatible in this case. It is not necessary to provide a new flexible PCB or gold fingers, and the increase in the display panel's manufacturing costs can be avoided. If the display panel comprises multiple flexible PCBs, the flying gold fingers of some of these boards can be electrically connected to the display panel's flying pins and used to transmit electrical signals.

[0048] In one possible embodiment, see Fig. 4. The pin group G1 comprises several first sub-pins G11 and several second sub-pins G12, located on both sides of the several first sub-pins G11.

The data lines 2 are electrically connected to the first sub-pins G11, and the common conductor track 6 is electrically connected to the second sub-pins G12.

[0049] In one possible embodiment, see Fig. 3A to Fig. 3E and Fig. 5, where Fig. 5 a cross-sectional view along the dashed line EF in Fig. If 3A is the case, the second conductor track 42 comprises a first partial conductor track section 421 and a second partial conductor track section 422. The third conductor track 43 comprises a third partial conductor track section 431 and a fourth partial conductor track section 432.

[0050] The display panel further comprises a first switching section 51 and a second switching section 52. The first partial conductor track section 421, the second partial conductor track section 422, and the first switching section 51 are each located on different layers. The third partial conductor track section 431, the fourth partial conductor track section 432, and the second switching section 52 are each located on different layers.

[0051] An orthogonal projection of the first switching section 51 on the first substrate 10 covers an orthogonal projection of part of the first partial conductor track section 421 on the first substrate 10 and an orthogonal projection of part of the second partial conductor track section 422 on the first substrate 10. The first partial conductor track section 421 and the second partial conductor track section 422 are conductively connected by the first switching section 51. An orthogonal projection of the second switching section 52 on the first substrate 10 covers an orthogonal projection of part of the third partial conductor section 431 on the first substrate 10 and an orthogonal projection of part of the fourth partial conductor section 432 on the first substrate 10. The third partial conductor section 431 and the fourth partial conductor section 432 are conductively connected by the second switching section 52.

[0052] In the embodiments described in this disclosure, the second conductor track 42 comprises a first partial conductor track section 421 and a second partial conductor track section 422. The third conductor track 43 comprises a third partial conductor track section 431 and a fourth partial conductor track section 432. The first partial conductor track section 421 and the second partial conductor track section 422 are conductively connected by the first mediating section 51, and the third partial conductor track section 431 and the fourth partial conductor track section 432 are conductively connected by the second mediating section 52. That is, if the sensor wire 4 is located near the circuit board, a connection to another layer is established. This allows the sensor wire 4 and the common conductor track to be in the same layer and both to be arranged in the layer of gate conductors. This facilitates the insertion of the sensor wire into the position of the solder plates.

[0053] In particular see Fig. 3A to Fig. 3E and Fig. 5. The array base plate can further comprise a first hole K1 and a second through-hole K2. The first through-hole K1 includes a first hole group K11 and a second hole group K12, which are arranged in the first direction X. The first hole group K11 includes several first partial through-holes K110, which are arranged in the second direction Y, and the second hole group K12 includes several second partial through-holes K120, which are arranged in the second direction Y. The first switching section 51 is conductively connected to the first partial conductor section 421 via the first partial through-holes K110, and the first switching section 51 is conductively connected to the second partial conductor section 422 via the second partial through-holes K120 to establish an electrical connection between the first partial conductor section 421 and the second partial conductor section 422.The second through-hole K2 comprises a third hole group K21 and a fourth hole group K22, arranged in the first direction X. The third hole group K21 comprises several third partial through-holes K210, arranged in the second direction Y, and the fourth hole group K22 comprises several fourth partial through-holes K220, arranged in the second direction Y. The second switching section 52 is conductively connected to the third partial conductor section 431 via the third partial through-holes K210 and conductively connected to the fourth partial conductor section 432 via the fourth partial through-holes K220, thus establishing an electrical connection between the third partial conductor section 431 and the fourth partial conductor section 432.In the embodiments described in this disclosure, the presence of several first partial through-holes K110 and several second partial through-holes K120 in the first through-hole K1 can ensure a good conductor connection between the first switching section 51 and the first partial conductor track section 421. Likewise, the presence of several third partial through-holes K210 and several fourth partial through-holes K220 in the second through-hole K2 can ensure a good conductor connection between the second switching section 52 and the fourth partial conductor track section 432.

[0054] In one possible embodiment, as in Fig. 3A- Fig. 3E and Fig. As shown in Figure 5, the first sub-conductor section 421 and the third sub-conductor section 431 are located on the same layer and are made of the same material as the second electrode section 33. The second sub-conductor section 422 and the fourth sub-conductor section 432 are located on the same layer and are made of the same material as the first electrode section 31. The first conductor 41 is located on the same layer and is made of the same material as the first electrode section 31. In this way, the problem of malfunction of the OD function due to temperature changes can be improved, and the operating performance of the display panel can be ensured at different temperatures without increasing the number of manufacturing steps for the display panel.

[0055] In one possible embodiment, as in Fig. 3A- Fig. 3E and Fig. As shown in Figure 5, data line 2 is located on the side of gate line 1 facing away from the first substrate 10. The display panel includes pixel electrodes and / or common electrodes arranged on the side of data line 2 facing away from gate line 1. The first electrode section 31 is on the same layer and is made of the same material as gate line 1. The second electrode section 33 is on the same layer and is made of the same material as data line 2. The first switching section 51 and the second switching section 52 are on the same layer and are made of the same material as the pixel electrode layer or the common electrode.In this way, the problem of malfunction of the OD function due to temperature changes can be improved, ensuring the operating performance of the display panel at different temperatures without increasing the manufacturing steps of the display panel.

[0056] Especially as in Fig. As shown in Figure 5, a gate isolation layer GI can be located between gate line 1 and data line 2, and a passivation layer PVX can be located between data line 2 and the pixel electrodes and / or common electrodes. The first partial-through holes K110 and the third partial-through holes K210 can penetrate the passivation layer PVX, and the second partial-through holes K120 and the fourth partial-through holes K220 can penetrate both the passivation layer PVX and the gate isolation layer GI.

[0057] In one possible embodiment, as in Fig. 6 shown ( Fig. 6 can show an enlarged representation of the dashed circle S2 in Fig. 4), at least one of the second partial conductor track sections 422 and the fourth partial conductor track section 432 has multiple perforated areas P0. In the embodiments of this disclosure, since the second partial conductor track section 422 and the fourth partial conductor track section 432 are located in the outer region of the display area AA, which is covered by the frame sealing adhesive, and since the second partial conductor track section 422 and the fourth partial conductor track section 432 have multiple perforated areas P0, the ultraviolet light used to cure the frame sealing adhesive can penetrate the second partial conductor track section 422 and the fourth partial conductor track section 432, thus avoiding the problem of the frame sealing adhesive not being properly cured by ultraviolet light.

[0058] In one possible embodiment, as in Fig. As shown in Figure 6, the common conductor track 6 has a first perforated section P1. The common conductor track 6 is arranged at least partially between adjacent fan-shaped conductor track regions F. An orthogonal projection of the temperature sensor 3 onto the first substrate 10 lies within an orthogonal projection of the first perforated section P1 onto the first substrate 10. In the embodiments of this disclosure, the arrangement of the temperature sensor 3 at the position of the first perforated section P1 of the common conductor track 6 allows for a compact design of both the common conductor track 6 and the arrangement of the temperature sensor 3, which is advantageous for the uniformity of the metal photolithography at this location.

[0059] In one possible embodiment, as in Fig. As shown in Figure 6, the common conductor 6 further comprises several second perforated sections P2. The area of ​​the first perforated section P1 is larger than the area of ​​the second perforated sections P2. The common conductor 6 lies on the same layer and is made of the same material as the first electrode section 31. In the embodiments of this disclosure, since the common conductor 6 is located in the outer region of the display area AA, which is covered by the frame sealing adhesive, and the common conductor 6 has several second perforated sections P2, the ultraviolet light used to cure the frame sealing adhesive can penetrate the common conductor 6, potentially resulting in the frame sealing adhesive not being properly cured by ultraviolet light.

[0060] In one possible embodiment, as in Fig. 7 shown ( Fig. 7 can show an enlarged representation of the dashed circle S1 in Fig. In a conductor group Z (where 4 are present), the conductor group Z comprises several wires Z1. The spacing d1 between adjacent sensor wires 4 is 1.5 to 5 times greater than the spacing d2 between adjacent wires Z1. Since a large number of wires are arranged in the fan-shaped conductor area, the conductor density of the wires is set relatively high to reduce the frame's construction. The wire spacing is made finer, for example, 3 µm to 8 µm, assuming a stable process. The wire width d3 of the sensor wires 4 is 5 to 10 times greater than the wire width d4 of the wires Z1. Specifically, the spacing d2 between adjacent wires Z1 in the conductor group Z can be between 3 µm and 8 µm, for example, 3 µm, 4 µm, 5 µm, 5.3 µm, 6 µm, 7 µm, or 8 µm. The distance d1 between the sensor wires 4 can correspond to the distance of the signal lines (e.g. clock signal lines) of the gate driver circuit.The signal lines of the gate driver circuit extend a considerable distance into the non-display area, and the clock signal lines, for example, carry AC signals, so coupling effects can occur between the signal lines. Considering that the distance must not be too small when implementing the reduction of the non-display frame; that the sensor wires serve to detect or return signals, etc.; and that coupling effects between the signal lines will be avoided, the same distance as that of the gate driver circuit signal lines can be maintained. In particular, the distance d1 between the sensor wires 4 can be between 10 µm and 20 µm, for example, 10 µm, 11 µm, 15 µm, 16 µm, 17 µm, 18 µm, or 20 µm. The wire width d3 of the sensor wires 4 can be between 40µm~60µm, for example 40µm, 42µm, 48µm, 50µm, 52µm, 54µm or 60µm.The wire width d4 of the wires Z1 in the conductor track group Z can be between 5µm~10µm, for example 5 µm, 6 µm, 6.5 µm, 7 µm, 7.5 µm, 9 µm or 10 µm.

[0061] In one possible embodiment, as in Fig. 1 and Fig. 3A- Fig. As shown in Figure 3E, an orthogonal projection of the active section 32 onto the first substrate 10 has a rectangular shape. In particular, an orthogonal projection of the active section 32 onto the first substrate 10 has a square shape, i.e., the length of the side of the active section 32 in the first direction X is equal to the length of the side in the second direction Y. In the embodiments of this disclosure, the rectangular shape of the orthogonal projection of the active section 32 onto the first substrate 10 can result in the temperature sensor being square overall and difficult to detect from the outside. In contrast, if the temperature sensor were a right-angled quadrilateral and no black matrix prevented reflection from the metal layer, bright stripes could be observed from the outside.

[0062] In one possible embodiment, as in Fig. 1 and Fig. 3A- Fig. As shown in Figure 3E, an orthogonal projection of the first electrode segment 31 onto the first substrate 10 can also have a rectangular shape. Specifically, the orthogonal projection of the first electrode segment 31 onto the first substrate 10 has a square shape, meaning that the length of the side of the first electrode segment 31 in the first direction X is equal to the length of the side in the second direction Y. In this way, the temperature sensor can be square overall and difficult to detect from the outside. In contrast, if the temperature sensor were a right-angled quadrilateral, more pronounced bright stripes could be observed from the outside.

[0063] In one possible embodiment, as in Fig. As shown in Figure 8, the display panel further comprises at least one light sensor 7. The light sensor 7 is located on the same side of the display area AA as the fan-shaped conductor area F and outside the fan-shaped conductor area F. The light sensor 7 is designed to measure the brightness and adjust the brightness of the display panel according to the measured brightness. Fig. Figure 8 shows that the light sensor 7 and the temperature sensor 3 are arranged between the different fan-shaped conductor track regions. Of course, they can also be arranged between an adjacent fan-shaped conductor track region; that is, the light sensor 7 and the temperature sensor 3 can both be arranged in the region shown in Figure 8. Fig. 8 is specified for temperature sensor 3. This is not limited here.

[0064] In one possible embodiment, as in Fig. 9A- Fig. 9E shown ( Fig. 9B is a monomembrane representation of the first electrode section in Fig. 9A, Fig. 9C is a monomembrane representation of the active region in Fig. 9A, Fig. 9D is a monomembrane representation of the second electrode section in Fig. 9A, Fig. 9E is a monomembrane representation of the black matrix layer in Fig. 9A), the light sensor 7 has the same structure as the temperature sensor 3. This simplifies the manufacturing process and makes the display panel compatible for both temperature and light measurements. Additionally, in cases with identical structures, it can also be used as a temperature sensor when temperature measurement is required and as a light sensor when brightness measurement is needed. This means that the integration of the temperature sensor is compatible with the design of the light sensor, and the manufacturing of components with two different functions is achieved in a single process. Optionally, both the temperature sensor and the light sensor can be positioned in the same location between two adjacent fan-shaped conductor areas, or they can be positioned in different locations between two adjacent fan-shaped conductor areas.In this case, both the temperature sensor and the light sensor can be integrated into the display panel. A simple manufacturing process allows the display panel to support both functions, improving the display quality and the level of integration.

[0065] In particular, the conformity of the structure of the light sensor 7 with the structure of the temperature sensor 3 can consist of the complete match between the structure of the light sensor 7, the membrane composition, the pattern shape of each membrane, and the process parameters of the temperature sensor 3. Of course, in a concrete implementation, the structure of the light sensor 7 and the membrane composition and pattern shape of each membrane of the temperature sensor 3 can also differ partially. For example, as in Fig. 9A and Fig. Figure 9B shows that the first electrode sections 31 of two partial light sensors 71 form a connected structure.

[0066] In one possible embodiment, as in Fig. 9A- Fig. As shown in Figure 9E, the light sensor 7 comprises two partial light sensors 70. The display panel further has a black matrix layer 8, which has a first black matrix opening 81. The orthogonal projection of one of the partial light sensors 70 of the light sensor 7 onto the first substrate 10 lies within the first black matrix opening 81, while the other partial light sensor 71 is covered by the black matrix layer 8. In the embodiments of this disclosure, the light sensor 7 also uses a two-transistor structure. The process parameters of the two transistors are completely identical to those of the temperature sensor. One of the partial light sensors 71 is not covered by the black matrix (i.e., it is located in the region of the first black matrix opening 81), so that it can be illuminated by ambient light, while the other partial light sensor 71 cannot be illuminated by ambient light.This allows the ambient brightness to be measured by the brightness difference between the two partial light sensors. In this case, the black matrix can be located either on the opposite base plate, which faces the array base plate, or on the side of the array base plate. This is not a limitation.

[0067] In one possible embodiment, as in Fig. As shown in Figure 9A, the outer contour of the active section in the partial light sensor 71 has a square shape. This avoids the problem of bright streaks caused by reflection from the metal layer in areas without black matrix coverage.

[0068] Especially as in Fig. 10A shown ( Fig. 10A can be the equivalent circuit diagram of Fig. The partial light sensor 71 (9A) has a three-terminal field-effect transistor structure, where the three terminals are PS, PG, and PD. Two partial light sensors 71 use the same PS and PG electrodes, while the PD electrodes are used independently.

[0069] Especially as in Fig. Figure 10B shows the behavior of the light sensor's characteristics as a function of light. When the ambient light changes from darkness to 5000 nits, the inrush current Ion increases only slightly, while the offrush current Ioff increases significantly. The offrush current Ioff is more sensitive to changes in ambient light, but its value is so small that it is difficult to detect. In normal operation, PG can be set to -8V (this is the point at which the light sensor is most sensitive to light and can be adjusted depending on the conditions of the external driver circuit; the sensor's most sensitive point to light may vary under different process conditions), PS can be set to 0V, and PD1 and PD2 can be set to 15V.After the partial light sensor 71 at the first black matrix aperture 81 is illuminated by ambient light, the current value increases compared to the partial light sensor 71 that is covered by the black matrix, and the increase is proportional to the light intensity. The current difference between PD1 and PD2 is taken as a reference value under these ambient light conditions to adjust the brightness of the backlight source.

[0070] In one possible embodiment, as in Fig. As shown in Figure 11, the display panel has a first axis of symmetry k1. The first axis of symmetry k1 passes through the center point of at least one temperature sensor 3.

[0071] In one possible embodiment, as in Fig. As shown in Figure 11, the display panel further comprises a first side area B1, which is opposite the fan-shaped conductor area F, as well as a second side area B2 and a third side area B3, which connect the side on which the fan-shaped conductor area F is located to the first side area B1. The first side area B1, the second side area B2, and the third side area B3 are located on one side of the display area AA. At least one of the areas of the first side area B1, the second side area B2, and the third side area B3 is provided with a temperature sensor 3.In the embodiments described in this disclosure, in addition to the arrangement of a temperature sensor 3 on the side where the fan-shaped conductor track area F is located, a temperature sensor 3 is also arranged in the areas of the first side area B1, the second side area B2, and the third side area B3, which can effectively increase the detection accuracy. Particularly in large display products, there can be large temperature differences at different locations.

[0072] In one possible embodiment, the first electrode section 31 of at least one of the temperature sensor 3 and the light sensor 7 is configured to apply a square wave signal to activate the temperature sensor 3 and / or the light sensor 7 at preset time intervals. Specifically, a square wave signal (AC signal) is applied to the first electrode section of the temperature sensor 3 and the light sensor 7, i.e., they are activated at preset time intervals, for example, every 10 seconds. This prevents the transistors from being constantly switched on, which would lead to drift of the temperature sensor 3 and the light sensor 7. The square wave signal can, for example, be a PWM signal.

[0073] In particular, a pixel circuit, which may contain a pixel circuit transistor, can be arranged in the display area AA. The individual diaphragms of the temperature sensor 3 and the light sensor 7 can be manufactured in the same layer and using the same process as the respective corresponding diaphragms of the pixel circuit transistor.

[0074] Based on the same inventive concept, the embodiment of this disclosure also provides a display device comprising the display panel described in the embodiments of this disclosure.

[0075] In one possible embodiment, as in Fig. 1, Fig. 8 and Fig. As shown in Figure 11, the display device further comprises a first printed circuit board C1, which is electrically connected to the display panel. The first printed circuit board C1 is provided with a first processor D1, which processes the temperature signal detected by the temperature sensor 3 to generate a first signal. In particular, the first printed circuit board C1 can be a printed circuit board (PCB), and the first processor D1 can be an operational amplifier (OP) to amplify, add, subtract, or differentiate the signal detected by the temperature sensor 3 or the light sensor 7. For example, it can apply a differential method to the signals received from the two sub-sensors 71 of the light sensor 7 to obtain the detected ambient light signal after removing other interference.

[0076] In one possible embodiment, as in Fig. 1, Fig. 8 and Fig. As shown in Figure 11, the display device further comprises a second printed circuit board C2, which is arranged on the side of the first printed circuit board C1 that is away from the display panel and is electrically connected to the first printed circuit board C1.

[0077] The second circuit board C2 includes a second processor D2, configured to process the first signal and generate a second signal. The display device further includes a third processor D3. The third memory D3 stores at least a first memory table corresponding to room temperature, a second memory table corresponding to a first threshold, and a third memory table corresponding to a second threshold. The third processor D3 is configured to retrieve the first, second, or third memory table based on the second signal in order to apply the voltage to the data line depending on the gray level in the first, second, or third memory table.

[0078] 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 detected temperature signal via the MCU into a specific target value and sends it via the I2C line to the TCON to call the corresponding OD table. Signal acquisition is performed by in-phase proportional magnification.

[0079] Especially as in Fig. 1, Fig. 8 and Fig. As shown in Figure 11, one end of the first processor D1 can be electrically connected to the temperature sensor 3, and the other end can be electrically connected to the second processor D2. The second processor D2 is electrically connected to the third processor D3.

[0080] In one possible embodiment, as in Fig.As shown in Figure 8, the display device comprises a backlight source on the rear 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 can be an LED driver. Specifically, the fourth processor D4 can be electrically connected to the second processor D2 and also electrically connected to the backlight source connector of the display panel. The light sensor sends the received light signal via the op-amp to the MCU processing unit. The MCU sends the processed target signal to the BLU to adjust the backlight brightness.

[0081] In contrast to conventional display panels with OD functionality, the display panel in the embodiments of this disclosure, through the integrated design of the temperature sensor in combination with the OD setting, ensures normal image display under high / low temperatures and improves the operating stability of the panel. Unlike conventional external temperature sensors, the temperature sensor in the display panel of this embodiment is integrated within the display panel and does not occupy additional space or increase the volume of the display panel. The temperature sensor uses a bottom-gate thin-film transistor structure that is compatible with the conventional liquid crystal panel process. No additional photolithography process is required, and the temperature sensor is manufactured along with other structures in the liquid crystal panel without increasing manufacturing costs.Unlike conventional external temperature sensors, the integrated design and circuitry of the temperature sensor in this embodiment's display panel are compatible with the existing LCD driver circuitry and require only minor modifications. The integrated design of the temperature sensor in this embodiment's display panel can be compatible with the integrated design of the light sensor; that is, both the temperature and light sensors can be integrated on the display panel to expand its functionality. Without altering the circuitry within the display panel, the light sensor can be easily used as a temperature sensor by adjusting the external driver circuitry, thus increasing the display panel's flexibility.
