For example, “substantially the same” may mean a difference relative to the stated value within one or more standard deviations, or within ±30%, 20%, 10%, or 5%.

For example, regions illustrated or described as flat may typically have rough and / or non-linear characteristics. Furthermore, sharp corners illustrated may be rounded. Thus, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0084] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0085] The liquid crystal cell (LCD) is the core of an LCD monitor, and the display effect of an LCD monitor is mainly affected by the LCD cell. The main parameters of the LCD cell include transmittance, contrast ratio, viewing angle, response time, and driving voltage. Among these, response time characterizes the time required for the LCD cell, driven by the pixel voltage, for the torque of the external electric field to overcome the resistance generated by the elastic coefficient and viscosity of the liquid crystal molecules, allowing the liquid crystal molecules to switch between bright (white) and dark (black) states. The longer the response time, the easier it is for the human eye to observe image trailing.

[0086] In previous designs, overdrive (OD) technology was used to address the issue of excessively long response times. However, the response time of liquid crystal molecules is easily affected by temperature, especially for negatively charged liquid crystal molecules. When the ambient temperature of the liquid crystal molecules changes, the response time also changes. The OD settings may not correspond to the response time after the temperature change, leading to display problems. When the temperature decreases, the deflection 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 deflection speed of the liquid crystal molecules speeds up, and the original OD function becomes excessive, resulting in color inversion and image trailing.

[0087] In view of this, the present disclosure provides a display panel, see [link to relevant documentation]. Figure 1 As shown, the display panel includes a display area AA and multiple fan-shaped trace areas F located on one side of the display area AA.

[0088] Multiple grid lines 1 extend along the first direction X and are located in the display area AA;

[0089] Multiple data lines 2 extend along the second direction Y, intersect with the gate line 1, and are located in the display area AA;

[0090] Multiple trace groups Z, at least one of the trace groups Z is located in at least one sector trace area F among multiple sector trace areas F. Specifically, the sector trace area F can correspond one-to-one with the trace group Z, and one sector trace area F is provided with one trace group Z; at least some trace groups Z are electrically connected to data line 2. The trace group includes multiple traces, and the traces in the trace group are electrically connected to the data line to provide data signals to the data line.

[0091] At least one temperature sensor 3 is located on the same side of the display area AA as the sector wiring area F, and at least a portion of the temperature sensor 3 is located in the area between adjacent sector wiring areas F;

[0092] Temperature sensor 3 is configured to detect ambient temperature so that the display panel applies voltage to data line 2 based on the temperature detected by temperature sensor 3. Specifically, when the temperature detected by temperature sensor 3 is within a first threshold (which can be a temperature range below room temperature), the voltage applied to data line 2 is greater than the voltage applied at the same gray level at room temperature, to accelerate the deflection speed of the liquid crystal and avoid trailing defects; and when the detected temperature is within a second threshold (which can be a temperature range above room temperature), the voltage applied to data line 2 is less than the voltage applied at the same gray level at room temperature, to slow down the deflection speed of the liquid crystal and avoid anti-trailing defects. Specifically, a table of correspondence between temperature and gray level 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 detected temperature is within the first threshold, voltage is applied to data line 2 according to the first storage table; when the detected temperature is within the second threshold, voltage is applied to data line 2 according to the second storage table; and when the detected temperature is within the room temperature range, voltage is applied to data line 2 according to the third storage table. Specifically, the first threshold can correspond to a temperature below room temperature, and the second threshold can correspond to a temperature above room temperature. Specifically, in one possible implementation, the first storage table can be an OD parameter table set according to low temperature, the second storage table can be an OD parameter table set according to high temperature, and the third storage table can be an OD parameter table corresponding to room temperature. The OD parameter table includes the overdrive grayscale values ​​confirmed for the previous frame and the current frame. For example, the previous frame grayscale includes 0, 8, 16, 24, 32, 40, 48…240, 248, 255 grayscales (every 7 grayscale intervals, of course, other grayscale intervals can also be set, not limited here); the current frame grayscale includes 0, 8, 16, 24, 32, 40, 48…240, 248, 255 grayscales (every 7 grayscale intervals, of course, other grayscale intervals can also be set, not limited here); Example For example, if the previous frame's grayscale is 32 and the current frame's grayscale is 64, then the OD grayscale table corresponds to 84 grayscale (the current frame's grayscale is greater than the previous frame's grayscale, and the OD grayscale can be greater than the current frame's grayscale); for example, if the previous frame's grayscale is 168 and the current frame's grayscale is 40, then the OD grayscale table corresponds to 38 grayscale (the current frame's grayscale is less than the previous frame's grayscale, and the OD grayscale can be less than the current frame's grayscale); if the current frame's grayscale is equal to the previous frame's grayscale, the OD grayscale can be equal to the current frame's grayscale.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 (e.g., 50~60℃) and low temperature (-40~-30℃). The parameter tables corresponding to other temperatures are calculated and generated based on the detected temperature and the high temperature and low temperature parameter tables. This can reduce the storage of the tables.

[0093] In this embodiment, a temperature sensor 3 is disposed on the side of the fan-shaped trace area F of the display panel. The display panel applies a voltage to the data line 2 based on the temperature detected by the temperature sensor 3. When the temperature detected by the temperature sensor 3 is low or high, the OD table corresponding to different temperatures is invoked to ensure that the liquid crystal molecules maintain the same (normal) deflection speed at different temperatures. This allows the display panel to adjust the OD parameters in real time according to changes in ambient temperature, ensuring normal image display and improving the problem of OD function failure caused by temperature changes. This also ensures the working performance of the display panel at different temperatures. Furthermore, compared to other sides of the display panel, in this embodiment, the temperature sensor 3 is located on the side of the fan-shaped trace area F of the display panel, which avoids the possibility that the signal detected by the temperature sensor 3 itself may be too low. If the temperature sensor 3 is located far from the circuit board side where the fan-shaped trace area F is bonded, the longer trace will affect the measured signal strength, leading to inaccurate signal. Moreover, since the temperature sensor 3 is located on the side of the fan-shaped trace area F of the display panel, it has little impact on the internal wiring of the display panel. Furthermore, the wiring space between the fan-shaped trace areas of the display panel is relatively large. When a common trace is set in the area between the fan-shaped traces, the wiring of the common trace can be adjusted to set up the temperature sensor. Since the wiring area of ​​the common trace is relatively large compared to the area of ​​other display signal lines, adjusting the common trace to set up the sensor will give the display panel new functions without significantly affecting the common trace signal and the display effect. In other words, it can give the display panel new functions while ensuring normal display and improving display quality.

[0094] In one possible implementation, see Figure 1 , Figures 2A-2E As shown, where, Figure 2A for Figure 1 An enlarged schematic diagram of temperature sensor 3. Figure 2B for Figure 2A The equivalent circuit diagram, Figure 2C for Figure 2A A schematic diagram of the single-film layer of the first electrode section. Figure 2D for Figure 2A A schematic diagram of a single-film layer in the active part. Figure 2E for Figure 2AA schematic diagram of a single-film layer of the second electrode portion is shown. The display panel includes an array substrate P1 and a counter substrate P2 disposed opposite to each other. A temperature sensor 3 is located on the array substrate P1. The array substrate P1 has a first substrate 10. The temperature sensor 3 includes a first electrode portion 31, an active portion 32 located on the 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 a portion of the orthographic projection of the second electrode portion 33 on the first substrate 10. Specifically, a control signal can be applied to a first trace 41 electrically connected to the first electrode portion 31, and a signal corresponding to the temperature can be obtained by measuring the signal between the second trace 42 and the third trace 43 electrically connected to the second electrode portion 33.

[0095] For details, see Figure 1 As shown, on the side where the fan-shaped trace area F is located, the temperature sensor 3 can be specifically set in the area between the outer edge of the display area AA and the outer edge of the opposing substrate P2.

[0096] In one possible implementation, see Figure 1 , Figures 2A-2E As shown, the second electrode portion 33 includes a first sub-portion 331 and a second sub-portion 332 disposed opposite to each other. The first sub-portion 331 includes a first main portion 3311 extending along a first direction and a plurality of first branches 3312 extending from the first main portion 3311 along a second direction Y. The second sub-portion 332 includes a second main portion 3321 extending along a first direction X and a plurality of second branches 3322 extending from the second main portion 3321 along a second direction Y. The first branches 3312 and the second branches 3322 are disposed intersecting.

[0097] For details, see Figure 2A and Figure 2BAs shown, the temperature sensor 3 can be a transistor. The first electrode 31 can serve as the control electrode TG, the first sub-electrode 331 can serve as the first electrode TD of the transistor, and the second sub-electrode 332 can serve as the second electrode TS of the transistor. The first electrode 31 controls the on / off state of the temperature sensor 3. By measuring the current signal between the first sub-electrode 331 and the second sub-electrode 332, the relevant signal detected by the temperature sensor 3 can be obtained. Specifically, the temperature sensor 3 can have the first electrode 31 made of gate layer metal, the active part 32 made of semiconductor active layer, and the second electrode 33 made of data line layer metal, leading out 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 (which can be adjusted according to the materials used, design scheme, etc.). In order to increase the detection accuracy of the sensor, the width-to-length ratio of the transistor in the sensor is larger than that of the transistor in the display area of ​​the display panel. The transistor in the display area is used to make electrical connections with the gate lines, data lines and pixel electrodes of the display panel. Optionally, in order to simplify the process, the transistor in the display area and the transistor structure contained in the temperature sensor or light sensor are fabricated using the same process, that is, the transistor in the display area and the sensor between the fan-shaped trace area are fabricated in the same layer and with the same material.

[0098] In one possible implementation, see Figure 1 , Figures 3A-3E As shown, where, Figure 3A for Figure 1 Another enlarged schematic diagram of temperature sensor 3. Figure 3B for Figure 3A The corresponding equivalent circuit diagram, Figure 3C for Figure 3A A schematic diagram of the single-film layer of the first electrode section. Figure 3D for Figure 3A A schematic diagram of a single-film layer in the active part. Figure 3E for Figure 3A A schematic diagram of a single-film layer of the second electrode portion shows that at least one temperature sensor 3 includes two first electrode portions 31 arranged along a 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 independently spaced apart; the two active portions 32 are independently spaced apart; 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 independently spaced apart. In this embodiment, the temperature sensor 3 adopts a dual-transistor structure, and the structure and process parameters of the two transistors can be completely identical; the two transistors use the same first main portion 3331, and the first electrode portions 31 and the second main portions 3321 are used independently. In specific implementation, combined with... Figure 3BAs shown, only one transistor can be set to normal operation, with its three terminals set with appropriate voltages (e.g., TG1 = -8V, TS = 0V, TD1 = 15V). The other transistor is not working, and the voltage condition is set to TG2 = TD2 = TS to ensure that the three terminals have the same potential and avoid characteristic drift. The two transistors periodically switch their operating states according to the usage time to avoid characteristic drift caused by long-term operation, increase the service life of the temperature sensor, and improve the detection accuracy of the temperature sensor.

[0099] For details, see Figure 3F As shown, the temperature sensor transfer curve changes with temperature. When the ambient temperature rises from -20℃ to 60℃, the increase in the on-state current Ion is not significant, while the increase in the off-state current Ioff is significant. The off-state current Ioff is more sensitive to temperature changes. However, the off-state current Ioff value is small, making it difficult to detect and susceptible to noise. The off-state current Ioff or the on-state current Ion can be selected as the detection signal of the temperature sensor depending on the specific situation.

[0100] In one possible implementation, see Figure 1 , Figures 3A-3E and Figure 4 As shown, the display panel also includes: multiple sensor leads 4; the multiple sensor leads 4 include: a first trace 41 with one end electrically connected to the first electrode part 31 and extending away from the display area AA, a second trace 42 with one end electrically connected to the first main part 3311 and extending away from the display area AA, and a third trace 43 with one end electrically connected to the second main part 3321 and extending away from the display area AA.

[0101] The display panel also includes: a pin group G1 electrically connected to the trace group Z, and a floating pin group G2 located outside the pin group G1; the floating pin group G2 includes a first floating pin G21, a second floating pin G22, and a third floating pin G23.

[0103] In this embodiment, the sensor lead 4 is electrically connected to the floating pin group G2 outside the pin group G1. The floating pins are electrically connected to the floating gold fingers on the flexible circuit board. In conventional display panels, the flexible circuit board electrically connected to the display panel has some floating gold fingers. The floating gold fingers do not provide signals. In this invention, the floating gold fingers of the flexible circuit board can be used to transmit the signals of the sensor. That is, by setting floating pins on the display panel corresponding to the floating gold fingers of the flexible circuit board, the floating pins and floating gold fingers are electrically connected to transmit signals. In this way, the existing flexible circuit board can be used to be compatible with the transmission of sensor signals in this invention, avoiding the need to configure new flexible circuit boards or gold fingers, and avoiding increasing the manufacturing cost of the display panel. When the display panel includes multiple flexible circuit boards, the floating gold fingers of some flexible circuit boards can be electrically connected to the floating pins of the display panel for transmitting electrical signals.

[0104] In one possible implementation, see Figure 4 As shown, pin group G1 includes: multiple first sub-pins G11, and multiple second sub-pins G12 located on both sides of the multiple first sub-pins G11; the display panel also includes: a common trace 6 (the common trace is set between adjacent fan-shaped trace areas, Figure 4 (not shown in the diagram), wherein data line 2 is electrically connected to the first sub-pin G11, and common trace 6 is electrically connected to the second sub-pin G12.

[0105] In one possible implementation, see Figures 3A-3E and Figure 5 As shown, where, Figure 5 It can be Figure 3A A cross-sectional diagram at the dashed line EF shows that the second trace 42 includes a first sub-trace section 421 and a second sub-trace section 422; the third trace 43 includes a third sub-trace section 431 and a fourth sub-trace section 432.

[0106] The display panel also includes: a first adapter 51 and a second adapter 52; the first sub-wiring section 421, the second sub-wiring section 422, and the first adapter 51 are all located on different layers, and the third sub-wiring section 431, the fourth sub-wiring section 432, and the second adapter 52 are all located on different layers.

[0107] The first adapter 51 is projected onto the first substrate 10, covering the portion of the first sub-trace 421 and the portion of the second sub-trace 422. The first sub-trace 421 and the second sub-trace 422 are connected through the first adapter 51. The second adapter 52 is projected onto the first substrate 10, covering the portion of the third sub-trace 431 and the portion of the fourth sub-trace 432. The third sub-trace 431 and the fourth sub-trace 432 are connected through the second adapter 52.

[0108] In this embodiment, the second trace 42 includes a first sub-trace portion 421 and a second sub-trace portion 422; the third trace 43 includes a third sub-trace portion 431 and a fourth sub-trace portion 432. The first sub-trace portion 421 and the second sub-trace portion 422 are connected by a first adapter portion 51, and the third sub-trace portion 431 and the fourth sub-trace portion 432 are connected by a second adapter portion 52. That is, when the sensor lead 4 is close to the circuit board side, it is connected to a different layer. In other words, the sensor lead 4 and the common trace can be 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 pad.

[0109] For details, see Figures 3A-3E and Figure 5As shown, the array substrate may further include a first via K1 and a second via K2. The first via K1 includes a first group of vias K11 and a second group of vias K12 arranged along a first direction X. The first group of vias K11 includes a plurality of first sub-vias K110 arranged along a second direction Y, and the second group of vias K12 includes a plurality of second sub-vias K120 arranged along a second direction Y. The first transition section 51 is connected to the first sub-trace section 421 through the first sub-vias K110, and the first transition section 51 is connected to the second sub-trace section 422 through the second sub-vias K120, thereby realizing the first sub-trace section 421. The second sub-routing section 422 is 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 section 52 is connected to the third sub-routing section 431 through the third sub-vias K210, and the second adapter section 52 is connected to the fourth sub-routing section 432 through the fourth sub-vias K220, thereby realizing the electrical connection between the third sub-routing section 431 and the fourth sub-routing section 432. In this embodiment of the present disclosure, the first via K1 includes a plurality of first sub-vias K110 and a plurality of second sub-vias K120, which can enable good communication between the first adapter 51 and the first sub-trace 421; and the second via K2 includes a plurality of third sub-vias K210 and a plurality of fourth sub-vias K220, which can enable good communication between the second adapter 52 and the fourth sub-trace 432.

[0110] In one possible implementation, see Figures 3A-3E and Figure 5 As shown, the first sub-trace section 421 and the third sub-trace section 431 are in the same layer and made of the same material as the second electrode section 33; the second sub-trace section 422 and the fourth sub-trace section 432 are in the same layer and made of the same material as the first electrode section 31; and the first trace 41 is in the same layer and made of the same material as the first electrode section 31. In this way, while improving the problem of OD function failure caused by temperature changes and ensuring the working performance of the display panel at different temperatures, it is possible to avoid increasing the manufacturing process of the display panel.

[0111] In one possible implementation, see Figures 3A-3E and Figure 5As shown, data line 2 is located on the side of gate line 1 facing away from the 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 is in the same layer and made of the same material as gate line 1; a second electrode portion 33 is in the same layer and made of the same material as data line 2; a first adapter portion 51 and a second adapter portion 52 are in the same layer and made of the same material as the pixel electrode layer or the common electrode. Thus, while improving the problem of OD function failure caused by temperature changes and ensuring the working performance of the display panel at different temperatures, it is possible to avoid increasing the manufacturing process of the display panel.

[0112] For details, see Figure 5 As shown, a gate insulating layer GI may be present between gate line 1 and data line 2, and a passivation layer PVX may be present between data line 2 and pixel electrode and / or 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.

[0113] In one possible implementation, see Figure 6 As shown, Figure 6 It can be Figure 4 An enlarged schematic diagram of the dashed coil S2 shows that at least one of the second sub-wiring portion 422 and the fourth sub-wiring portion 432 has multiple hollow areas P0. In this embodiment, since the second sub-wiring portion 422 and the fourth sub-wiring portion 432 are located in the outer area of ​​the display area AA, which is the area covered by the sealant, the multiple hollow areas P0 in the second sub-wiring portion 422 and the fourth sub-wiring portion 432 allow the ultraviolet light for curing the sealant to pass through them, avoiding the problem of the sealant not being able to cure properly under ultraviolet light.

[0114] In one possible implementation, see Figure 6 As shown, the common trace 6 has a first cutout portion P1, and the common trace 6 is at least partially disposed between adjacent fan-shaped trace areas F; the temperature sensor 3 is located within the orthographic projection of the first substrate 10, within the orthographic projection of the first cutout portion P1 of the first substrate 10. In this embodiment, placing the temperature sensor 3 at the position of the first cutout portion P1 of the common trace 6 allows for a compact arrangement of the wiring of the common trace 6 and the temperature sensor 3, which is beneficial for the uniformity of metal lithography at that location.

[0115] In one possible implementation, see Figure 6As shown, the common trace 6 also has multiple second cutouts P2, and the area of ​​the first cutout P1 is larger than the area of ​​the second cutout P2; the common trace 6 and the first electrode portion 31 are in the same layer and made of the same material. In this embodiment, since the common trace 6 is located in the outer area of ​​the display area AA, which is the area covered by the sealant, the common trace 6 has multiple second cutouts P2, which allows the ultraviolet light for curing the sealant to pass through the common trace 6, avoiding the problem of the sealant not being able to cure properly under ultraviolet light.

[0116] In one possible implementation, see Figure 7 As shown, Figure 7 It can be Figure 4 The enlarged schematic diagram at the dashed circle S1 shows that the wiring group Z includes multiple leads Z1; the spacing d1 between adjacent sensor leads 4 is 1.5 to 5 times the spacing d2 between adjacent leads Z1. Since there are many leads in the fan-shaped wiring area, the wiring density will be set higher in order to reduce the design of the frame, and the line spacing will be made finer, for example, 3μm to 8μm, while ensuring the stability of the process; 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 within the trace group Z can be 3μm to 8μm, for example, 3μm, 4μm, 5μm, 5.3μm, 6μm, 7μm, or 8μm. The spacing d1 of the sensor lead 4 can be equal to the spacing of the signal lines (e.g., clock signal lines) of the gate drive circuit. Since the signal lines of the gate drive circuit extend relatively far in the non-display area, and, for example, clock signal lines transmit AC signals, there will be coupling between the signal lines. Therefore, to reduce the non-display bezel, the spacing cannot be too close. Because the sensor leads need to detect or provide feedback signals, to avoid coupling between signal lines, they can be kept close to the gate drive circuit. The spacing of the signal lines is consistent. Specifically, the spacing d1 of the sensor lead 4 can be 10μm to 20μm, for example, 10μm, 11μm, 15μm, 16μm, 17μm, 18μm, or 20μm; the line width d3 of the sensor lead 4 can be 40μm to 60μm, for example, 40μm, 42μm, 48μm, 50μm, 52μm, 54μm, or 60μm; the line width d4 of the lead Z1 in the wiring group Z can be 5μm to 10μm, for example, 5μm, 6μm, 6.5μm, 7μm, 7.5μm, 9μm, or 10μm.

[0117] In one possible implementation, see Figure 1 , Figures 3A-3EAs shown, the active part 32 has a square shape in its orthographic projection onto the first substrate 10. Specifically, the active part 32 has a square shape in its orthographic projection onto the first substrate 10, meaning that the side length of the active part 32 along the first direction X is equal to the side length along the second direction Y. In this embodiment, the square shape of the active part 32 in its orthographic projection onto the first substrate 10 makes the temperature sensor as a whole square, which is not easily observed from the outside. In contrast, if the temperature sensor were rectangular, bright bars might be observed from the outside due to the reflection of the metal layer if there were no black matrix to block the light.

[0118] In one possible implementation, see Figure 1 , Figures 3A-3E As shown, the orthographic projection shape of the first electrode portion 31 onto the first substrate 10 can also be square. Specifically, the orthographic projection shape of the first electrode portion 31 onto the first substrate 10 is a square, that is, the side length of the first electrode portion 31 along the first direction X is equal to the side length along the second direction Y. In this way, the temperature sensor can be made into a square shape, which is not easily observed from the outside, compared to when the temperature sensor is rectangular, where a more obvious bright bar can be observed from the outside.

[0119] In one possible implementation, see Figure 8 As shown, the display panel also includes at least one light sensor 7, which is located on the same side of the display area AA as the fan-shaped trace area F, and is located outside the fan-shaped trace area F. The light sensor 7 is configured to detect brightness to adjust the brightness of the display panel according to the detected brightness. See also Figure 8 This illustrates that the light sensor 7 and the temperature sensor 3 are respectively positioned between different sector-shaped trace areas. Of course, they can also be positioned between an adjacent sector-shaped trace area, that is, both the light sensor 7 and the temperature sensor 3 are positioned between different sector-shaped trace areas. Figure 8 The area corresponding to temperature sensor 3 is not limited here.

[0120] In one possible implementation, see Figures 9A-9E As shown, where, Figure 9B for Figure 9A A schematic diagram of the single-film layer of the first electrode section. Figure 9C for Figure 9A A schematic diagram of a single-film layer in the active part. Figure 9D for Figure 9A A schematic diagram of the single-film layer of the second electrode section. Figure 9E for Figure 9AThe schematic diagram shows a single-film layer of the black matrix layer. The structure of the light sensor 7 is the same as that of the temperature sensor 3, which simplifies the fabrication process and allows the display panel to be compatible with both temperature and light detection. Alternatively, with the same structure, it can function as a temperature sensor when temperature detection is required, and as a light sensor when light detection is required. This means the temperature sensor and light sensor are integrated and designed to be compatible, allowing the fabrication of two different functional devices in a single process. Optionally, the temperature sensor and light sensor can both be located at a corresponding position between two adjacent fan-shaped trace areas, or they can be located at different positions between two adjacent fan-shaped trace areas. In this case, both the temperature sensor and light sensor are located in the display panel. Through a simplified fabrication process, the panel can be compatible with both functions, improving display quality and the integration of the display panel.

[0121] Specifically, the structure of the light sensor 7 is the same as that of the temperature sensor 3. The composition of the film layers, the pattern shape of each film layer, and the process parameters of the light sensor 7 and the temperature sensor 3 can be completely identical. Of course, in specific implementations, the composition of the film layers and the pattern shape of each film layer of the light sensor 7 and the temperature sensor 3 can also be partially different. For example, such as... Figure 9A and Figure 9B As shown, the first electrode portion 31 of the two sub-light sensors 71 can be an integrally connected structure.

[0122] In one possible implementation, see Figures 9A-9E As shown, the light sensor 7 includes two sub-light sensors 70; the display panel also has a black matrix layer 8, which has a first black matrix opening 81. One of the sub-light sensors 70 is projected onto the first substrate 10 within the first black matrix opening 81, while the other sub-light sensor 71 is obscured by the black matrix layer 8. In this embodiment, the light sensor 7 also employs a dual-transistor structure, with the process parameters of the two transistors being identical to those of the temperature sensor. One sub-light sensor 71 is not obscured by the black matrix (i.e., it is located in the area where the first black matrix opening 81 is located), meaning one sub-light sensor 71 can be illuminated by ambient light, while the other sub-light sensor 71 cannot be illuminated by ambient light, allowing the determination of external light intensity through the brightness difference between the two. In this case, the black matrix can be disposed on a facing substrate opposite to the array substrate, or it can be disposed on one side of the array substrate; this is not limited.

[0123] In one possible implementation, see Figure 9A As shown, the outer contour shape of the active part in the sub-illumination sensor 71 is square. This avoids the problem of bright stripes caused by reflections from the metal layer in areas not covered by the black matrix.

[0124] For details, see Figure 10A As shown, specifically, Figure 10A It can be Figure 9A The equivalent circuit diagram shows that the sub-light sensor 71 is a three-terminal field-effect transistor structure, with the three terminals being PS, PG, and PD respectively; the two sub-light sensors 71 use the same PS and PG electrodes, while the PD electrode is used independently.

[0125] For details, see Figure 10B As shown, the characteristics of the light sensor change with illumination. When the ambient light changes from darkness to 5000 nits, the increase in the on-state current Ion is not significant, while the increase in the off-state current Ioff is significant. The off-state current Ioff is more sensitive to changes in ambient light, but its value is small and not easily detected. During normal operation, PG can be set to -8V (the point where the light sensor is most sensitive to illumination, which can be adjusted according to the external driving circuit conditions; the point of most sensitivity to illumination may differ under different process conditions), PS can be set to 0V, and PD1 and PD2 can be set to 15V. After the sub-light sensor 71 at the opening 81 of the first black matrix is ​​illuminated by ambient light, its 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 a reference value under this ambient light condition and used to adjust the backlight brightness.

[0126] In one possible implementation, see Figure 11 As shown, the display panel has a first axis of symmetry k1; the first axis of symmetry k1 passes through the center of at least one temperature sensor 3.

[0127] In one possible implementation, see Figure 11 As shown, the display panel also includes a first side area B1 opposite to the fan-shaped trace area F, and a second side area B2 and a third side area B3 connecting the side where the fan-shaped trace area F is located with 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 first side area B1, the second side area B2, and the third side area B3 is provided with a temperature sensor 3. In this embodiment of the present disclosure, in addition to providing a temperature sensor 3 on the side where the fan-shaped trace area F is located, temperature sensors 3 are also provided in the first side area B1, the second side area B2, and the third side area B3, which can effectively improve the detection accuracy, especially for large-size display products, where the temperature at different locations may have significant differences.

[0128] In one possible implementation, 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, so that the temperature sensor 3 turns on at preset intervals, and / or the light sensor 7 turns on at preset intervals. Specifically, the first electrode portion of the temperature sensor 3 and the light sensor 7 is supplied with a square wave (AC) signal, that is, it turns on at preset intervals, for example, at 10-second intervals, so as to prevent the transistor from being continuously turned on, causing the temperature sensor 3 and the light sensor 7 to drift. The square wave signal is, for example, a PWM signal.

[0129] Specifically, the display area AA can be equipped with a pixel circuit, which can include various film layers of pixel circuit transistors, temperature sensor 3 and light sensor 7, and can be fabricated in the same layer and with the same process as the corresponding film layers of the pixel circuit transistors.

[0130] Based on the same inventive concept, embodiments of this disclosure also provide a display device, which includes a display panel as provided in embodiments of this disclosure.

[0131] In one possible implementation, see Figure 1 , Figure 8 and Figure 11 As shown, the display device also 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 form a first signal. Specifically, the first 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, and perform differential operations on the signal detected by the temperature sensor 3 or the light sensor 7. For example, differential operations can be performed on the signals received by the two sub-sensors 71 in the light sensor 7 to obtain the detected external light signal after removing interference from other factors.

[0132] In one possible implementation, see Figure 1 , Figure 8 and Figure 11 As shown, the display device also includes a second circuit board C2 located on the side of the first circuit board C1 away from the display panel and electrically connected to the first circuit board C1;

[0133] The second circuit board C2 includes a second processor D2 configured to process a first signal to form a second signal; the display device further includes a third processor D3, wherein 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 invoke the first memory table, the second memory table, or the third memory table according to the second signal to apply voltage to the data line according to the grayscale of the first memory table, the second memory table, or the third memory table.

[0134] 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 captures the temperature signal, which is then converted into a specific target value by the MCU and sent to the TCON via the I2C line to call the corresponding OD table. The signal acquisition method is in-phase proportional amplification.

[0135] For details, see Figure 1 , Figure 8 and Figure 11 As shown, 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.

[0136] In one possible implementation, see Figure 8 As shown, the display device includes a backlight on the backlight side of the panel and a fourth processor D4. The fourth processor D4 is configured to adjust the brightness of the backlight 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 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.

[0137] The display panel of this disclosure differs from traditional display panels with OD (October-Dip) functionality. Its integrated temperature sensor design, combined with OD adjustment, ensures normal display under high / low temperature conditions, improving panel stability. Unlike conventional external temperature sensors, the temperature sensor in this disclosure is integrated within the display panel, avoiding additional space and panel size. The temperature sensor employs a bottom-gate thin-film transistor structure, compatible with conventional LCD panel manufacturing processes, requiring no additional photolithography. The temperature sensor is fabricated along with other structures in the LCD panel, minimizing production costs. Unlike conventional external temperature sensors, the integrated temperature sensor design and driving scheme of this disclosure are compatible with existing LCD panel driving schemes, requiring minimal modification. This integrated temperature sensor design is also compatible with integrated light sensor design, allowing simultaneous integration of both temperature and light sensors on the display panel, expanding its functionality. Without altering the internal wiring of the display panel, the light sensor can be converted into a temperature sensor simply by adjusting the external driving circuit, enhancing the display panel's flexibility.
