[0059] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application.

[0060] In traditional LCD panels, liquid crystal molecules have the viscosity of liquid. Viscosity refers to the resistance encountered by liquid crystal molecules when they flow or rearrange. The higher the viscosity, the greater the resistance to movement. When using LCD panels in low temperature environments, the viscosity of liquid crystal molecules increases, and the speed of their rearrangement slows down, resulting in a longer response time of the LCD panel, resulting in smearing and color dragging, which affects the display quality of dynamic images.
[0061] Based on this, the embodiments of the present application provide a liquid crystal display panel and a display device, which can heat the liquid crystal molecules in a low-temperature environment, reduce the viscosity of the liquid crystal molecules, enable the liquid crystal molecules to rotate normally, improve the response speed of the liquid crystal display panel, avoid the phenomenon of ghosting and color dragging on the liquid crystal display panel, and effectively improve the display effect of the liquid crystal display panel.
[0062] The present application is described in detail below with reference to the accompanying drawings and embodiments.
[0063] See also Figure 1-Figure 3 , Figure 1 A schematic diagram of the structure of a liquid crystal display panel provided in one embodiment of the present application; Figure 2 for Figure 1 A cross-sectional view of the liquid crystal display panel along line AA; Figure 3 for Figure 1 The cross-sectional view of the liquid crystal display panel along line BB is shown. The embodiment of the present application provides a liquid crystal display panel 10 for displaying images; the liquid crystal display panel 10 may include a first substrate 1 , a second substrate 2 , a liquid crystal layer 4 and a coil 5 .
[0064] like Figure 2 As shown, the first substrate 1 and the second substrate 2 can be glass substrates. A thin film transistor (TFT) array (not shown) is provided on the first substrate 1 to control the display screen. A color filter (not shown) and a common electrode are provided on the second substrate 2; the color filter is used to filter light of different colors to form a color image, and the common electrode cooperates with the pixel electrode on the first substrate 1 to form an electric field.
[0065] Specifically, the second substrate 2 is arranged opposite to the first substrate 1 and is fixedly connected by a frame glue 3 arranged on the circumferential edge to prevent external water and oxygen from entering the liquid crystal display panel 10; wherein the first substrate 1, the second substrate 2 and the frame glue 3 are arranged to form a receiving cavity for receiving the liquid crystal molecules 41 and other structures.
[0066] The liquid crystal layer 4 is disposed in the accommodating cavity, and the liquid crystal layer 4 includes a plurality of liquid crystal molecules 41; the liquid crystal molecules 41 can change their arrangement direction under the control of an electric field, thereby controlling the passage of light, and further controlling the brightness of each pixel to form a display image. Alignment layers 42 are disposed on both sides of the liquid crystal layer 4 close to the first substrate 1 and the second substrate 2, for enabling the liquid crystal molecules to be uniformly arranged in a predetermined arrangement direction in an initial state.
[0067] Combination Figure 2 and Figure 3 , the coil 5 is arranged around the liquid crystal layer 4, and the coil 5 can generate an alternating magnetic field to heat the liquid crystal molecules 41 when powered on. The coil 5 is arranged around the axis direction of the liquid crystal display panel 10, and the axis direction is parallel to the liquid crystal display panel 10, so that the distance between the liquid crystal molecules 41 and the coil 5 is close enough, so that the magnetic field generated by the coil 5 when powered on heats the liquid crystal molecules 41; in addition, the coil 5 with more turns can be arranged on the liquid crystal display panel 10.
[0068] Combination Figure 1 and Figure 3 Optionally, the liquid crystal display panel 10 can be a rectangular panel, and the axial direction is parallel to the length direction X of the liquid crystal display panel 10, or parallel to the width direction Y of the liquid crystal display panel 10; so as to facilitate the arrangement of the coil 5 in the liquid crystal display panel 10.
[0069] The following embodiments of the present application are explained by taking the example that the axis direction is parallel to the length direction X of the liquid crystal display panel 10 .
[0070] Specifically, the liquid crystal molecules 41 can directly generate heat in the alternating magnetic field to increase their temperature; specifically, magnetic nanoparticles can be added to the liquid crystal molecules 41. Alternatively, magnetic nanoparticles can be arranged in the liquid crystal layer 4 to generate heat in the alternating magnetic field to increase the temperature of the liquid crystal layer 4, thereby indirectly heating the liquid crystal molecules 41.
[0071] By arranging the coil 5 on the liquid crystal display panel 10, when the liquid crystal display panel 10 is used in a low temperature environment, the coil 5 can be powered to generate an alternating magnetic field, thereby heating the liquid crystal molecules 41 using the principle of electromagnetic induction heating, reducing the viscosity of the liquid crystal molecules 41, allowing the liquid crystal molecules 41 to rotate normally, improving the response speed of the liquid crystal display panel 10, avoiding the phenomenon of smearing and color dragging on the liquid crystal display panel 10, and effectively improving the display effect of the liquid crystal display panel 10. In addition, the coil 5 is arranged around the liquid crystal layer 4 so that the liquid crystal layer 4 is at the center of the coil 5 with a larger magnetic field strength, which can effectively increase the heating rate of the liquid crystal molecules 41 and further improve the phenomenon of smearing and color dragging.
[0072] In a specific embodiment, the coil 5 may be disposed outside the first substrate 1 and the second substrate 2. Specifically, the coil 5 is a multi-turn coil 5, and each turn of the coil 5 includes a first wire segment 51, a second wire segment 54 and two welding wires 58.
[0073] Among them, Figure 3 As shown, the first wire segment 51 can be arranged on a side surface of the first substrate 1 away from the liquid crystal layer 4; the second wire segment 54 can be arranged on a side surface of the second substrate 2 away from the liquid crystal layer 4, that is, the first wire segment 51 and the second wire segment are arranged on the opposite side surfaces of the liquid crystal display panel 10 along the thickness direction Z. And the first wire segment 51 and the second wire segment 54 are arranged in a staggered manner, that is, along the thickness direction Z of the liquid crystal display panel 10, the first wire segment 51 and the second wire segment 54 are located on different planes. It can be understood that the first wire segment 51 arranged on the surface of the first substrate 1 and the second wire segment 54 arranged on the surface of the second substrate 2 constitute the main part of the coil 5.
[0074] The first wire segment 51 and the second wire segment 54 may also be arranged in parallel with the functional line 6 to prevent the coil 5 from affecting the electric field between the pixel electrode and the common electrode when it is energized, thereby affecting the deflection of the liquid crystal molecules 41 .
[0075] like Figure 2As shown, two welding wires 58 are respectively arranged on the surface of one side of the frame glue 3 located at both ends of the first wire segment 51 and the second wire segment 54 away from the liquid crystal layer 4. One of the two welding wires 58 is electrically connected to the first wire segment 51 and the second wire segment 54, respectively, so that the first wire segment 51 can be electrically connected to the second wire segment 54 through the welding wire 58. One end of the other welding wire 58 is electrically connected to the second wire segment 54, and the other end is electrically connected to the first wire segment 51 in the next turn of the coil 5, so that the second wire segment 54 can be electrically connected to the next turn of the coil 5 through the second gold ball 55 and the second connecting segment 56. In other words, one of the two welding wires 58 is used to connect the main part of the same turn of the coil 5, and the other is used to connect the main parts of two adjacent turns of the coil 5.
[0076] Thus, by arranging the coil 5 outside the first substrate 1 and the second substrate 2 of the liquid crystal display panel 10, the preparation process is simplified and the manufacturing cost is reduced. Specifically, the two welding wires 58 can be electrically connected to the first wire segment 51 and the second wire segment 54 by welding.
[0077] Combination Figure 2 and Figure 3 In a specific embodiment, the liquid crystal display panel 10 may further include a sealing layer 9; the sealing layer 9 covers the surface of the coil 5 and the outer surfaces of the first substrate 1, the second substrate 2 and the frame glue 3 that are not covered by the coil 5, so as to insulate the coil 5 and protect the coil 5 from being corroded by external water vapor. Specifically, the sealing layer 9 may be a transparent insulating material.
[0078] See also Figure 4-Figure 7 , Figure 4 A schematic diagram of the structure of a liquid crystal display panel provided in another embodiment of the present application; Figure 5a for Figure 4 A cross-sectional view of the liquid crystal display panel along line C1-C1; Figure 5b for Figure 4 A cross-sectional view of the liquid crystal display panel along line C2-C2; Figure 6 for Figure 4 A cross-sectional view of the liquid crystal display panel along line DD; Figure 7 for Figure 4 The wiring diagram of the coil of the liquid crystal display panel is shown.
[0079] In a specific embodiment, the coil 5 can also be arranged in the first substrate 1 and the second substrate 2; the coil 5 can be a multi-turn coil 5, and each turn of the coil 5 can include a first wire segment 51, a first gold ball 52, a first connecting segment 53, a second wire segment 54, a second gold ball 55 and a second connecting segment 56.
[0080] Combination Figure 5a and Figure 5b, wherein the first wire segment 51 is arranged on the side of the first substrate 1 facing the liquid crystal layer 4, and the second wire segment 54 is arranged on the side of the second substrate 2 facing the liquid crystal layer 4; and the first wire segment 51 and the second wire segment 54 are arranged in a staggered manner. It should be noted that the staggered arrangement means that the first wire segment 51 and the second wire segment 54 are not on the same plane in the direction perpendicular to the liquid crystal display panel 10. It can be understood that the first wire segment 51 arranged on the first substrate 1 and the second wire segment 54 arranged on the second substrate 2 constitute the main part of the coil 5.
[0081] Optionally, the first wire segment 51 and the second wire segment 54 may also be arranged in parallel and staggered.
[0082] Combination Figure 5a , Figure 5b and Figure 7 , the first gold ball 52 is arranged between the first substrate 1 and the second substrate 2 and penetrates the frame glue 3, and the first connecting segment 53 is electrically connected to the first gold ball 52; so that the first wire segment 51 and the second wire segment 54 can be electrically connected through the first gold ball 52 and the first connecting segment 53. Specifically, one of the first gold ball 52 and the first connecting segment 53 is electrically connected to the first wire segment 51, and the other is electrically connected to the second wire segment 54. Among them, the first gold ball 52 can be connected to the first wire segment 51, and the first connecting segment 53 can be connected to the second wire segment 54; or the first connecting segment 53 is connected to the first wire segment 51, and the first gold ball 52 is connected to the second wire segment 54. It can be understood that the first gold ball 52 and the first connecting segment 53 are used to connect the main part in the same turn coil 5.
[0083] The second gold ball 55 is disposed between the first substrate 1 and the second substrate 2 and penetrates the frame glue 3, and the second connecting segment 56 is electrically connected to the second gold ball 55; so that the second wire segment 54 can be electrically connected to the next turn coil 5 through the second gold ball 55 and the second connecting segment 56. Specifically, one of the second gold ball 55 and the second connecting segment 56 is electrically connected to the second wire segment 54, and the other is electrically connected to the first wire segment 51 in the next turn coil 5. Among them, the second gold ball 55 can be connected to the second wire segment 54, and the second connecting segment 56 can be electrically connected to the first wire segment 51 in the next turn coil 5; or the second connecting segment 56 is electrically connected to the second wire segment 54, and the second gold ball 55 is electrically connected to the first wire segment 51 in the next turn coil 5. It can be understood that the second gold ball 55 and the second connecting segment 56 are used to connect the main parts of two adjacent turns of coil 5.
[0084] In this way, by disposing the coil 5 in the first substrate 1 and the second substrate 2 of the liquid crystal display panel 10, the coil 5 is integrated into the internal film layer of the liquid crystal display panel 10, which effectively saves space and is conducive to the miniaturization design of the liquid crystal display panel 10.
[0085] like Figure 7 As shown, in a specific embodiment, the first connecting segment 53 and the second connecting segment 56 can be both arranged on the side of the first substrate 1 facing the liquid crystal layer 4. Specifically, one end of the first connecting segment 53 is electrically connected to the first wire segment 51, and the other end is electrically connected to the first gold ball 52; one end of the second connecting segment 56 is electrically connected to the second gold ball 55, and the other end is electrically connected to the first wire segment 51 in the next turn of the coil 5. Among them, the frame glue 3 of the first connecting segment 53 located at one end of the second wire segment 54 is within the projection range of the first substrate 1 along the thickness direction Z of the liquid crystal display panel 10, and the frame glue 3 of the second connecting segment 56 located at the other end of the second wire segment 54 is within the projection range of the first substrate 1 along the thickness direction Z of the liquid crystal display panel 10. In this way, the integrated design of the coil 5 is realized.
[0086] Of course, in other embodiments, the first connection segment 53 may also be disposed on the side of the first substrate 1 facing the liquid crystal layer 4; the second connection segment 56 may be disposed on the side of the second substrate 2 facing the liquid crystal layer 4. One end of the first connection segment 53 is electrically connected to the first wire segment 51, and the other end is electrically connected to the first gold ball 52; one end of the second connection segment 56 is electrically connected to the second wire segment 54, and the other end is electrically connected to the second gold ball 55.
[0087] Alternatively, the first connection segment 53 may be disposed on the side of the second substrate 2 facing the liquid crystal layer 4; the second connection segment 56 may be disposed on the side of the first substrate 1 facing the liquid crystal layer 4. One end of the first connection segment 53 is electrically connected to the first gold ball 52, and the other end is electrically connected to the second wire segment 54; one end of the second connection segment 56 is electrically connected to the second gold ball 55, and the other end is electrically connected to the first wire segment 51 in the next turn of the coil 5.
[0088] Alternatively, the first connecting segment 53 and the second connecting segment 56 may be both disposed on the side of the second substrate 2 facing the liquid crystal layer 4. One end of the first connecting segment 53 is electrically connected to the first gold ball 52, and the other end is electrically connected to the second wire segment 54; one end of the second connecting segment 56 is electrically connected to the second wire segment 54, and the other end is electrically connected to the second gold ball 55.
[0089] like Figure 6 As shown, in a specific embodiment, the liquid crystal display panel 10 may further include a first common electrode layer 7 disposed on the side of the first substrate 1 facing the liquid crystal layer 4, for providing a common voltage and forming an electric field with the pixel electrode to control the deflection of the liquid crystal molecules 41. The first common electrode layer 7 may be disposed in the same layer and spaced apart from the first wire segment 51, so that the first wire segment 51 and the first common electrode layer 7 may be manufactured by the same process, thereby simplifying the panel structure and reducing the manufacturing cost.
[0090] The liquid crystal display panel 10 may further include a second common electrode layer 8 disposed on the side of the second substrate 2 facing the liquid crystal layer 4, for providing a common voltage and forming an electric field with the pixel electrode to control the deflection of the liquid crystal molecules 41. The second common electrode layer 8 may be disposed in the same layer and spaced apart from the second wire segment 54, so that the second wire segment 54 and the second common electrode layer 8 may be manufactured by the same process, thereby simplifying the panel structure and reducing the manufacturing cost.
[0091] like Figure 6 As shown, in a specific embodiment, the liquid crystal display panel 10 may further include a plurality of parallel functional lines 6, so as to control the electric field between the pixel electrode and the common electrode through the plurality of functional lines 6, thereby controlling the display screen of the liquid crystal display panel 10. The first wire segment 51 and the second wire segment 54 may be arranged in parallel with the functional line 6, so as to avoid affecting the electric field between the pixel electrode and the common electrode when the coil 5 is energized, thereby affecting the deflection of the liquid crystal molecules 41; and the preparation of the first wire segment 51 and the second wire segment 54 is also convenient.
[0092] Specifically, the functional line 6 can be a data line or a scan line; that is, the first wire segment 51 and the second wire segment 54 can be spaced apart on the first substrate 1 and the second substrate 2 along the length direction X of the liquid crystal display panel 10, or can be spaced apart on the first substrate 1 and the second substrate 2 along the width direction Y of the liquid crystal display panel 10.
[0093] Among them, the functional line 6 corresponding to the first wire segment 51 and the second wire segment 54 in the same turn of the coil 5 can be two adjacent functional lines 6; or, the functional line 6 corresponding to the first wire segment 51 and the second wire segment 54 in the same turn of the coil 5 can also be two spaced functional lines 6, that is, there are multiple functional lines 6 between the functional lines 6 corresponding to the first wire segment 51 and the second wire segment 54.
[0094] See also Figure 8 , Figure 8 A wiring diagram of a coil of a liquid crystal display panel provided in another embodiment of the present application; in a specific embodiment, when the first connecting segment 53 and the second connecting segment 56 are both arranged on the side of the first substrate 1 facing the liquid crystal layer 4, part of the functional line 6 can be used as the first wire segment 51 to further simplify the panel structure and reduce the manufacturing cost. Among them, the first connecting segment 53 and the second connecting segment 56 can be arranged on the same layer as the first wire segment 51, and switches 57 are arranged on the first connecting segment 53 and the second connecting segment 56 to control whether the first connecting segment 53 and the second connecting segment 56 are turned on. The second wire segment 54 is arranged in alignment with another part of the adjacent functional line 6.
[0095] Specifically, the switch 57 can be a thin film transistor, so that when preparing the TFT array on the first substrate 1, the thin film transistor can be prepared on the first connecting segment 53 and the second connecting segment 56 at the same time, thereby avoiding increasing the preparation process and manufacturing cost. When the switch 57 is in the on state, part of the functional line 6 is electrically connected to the second wire segment 54 as the first wire segment 51, and the coil 5 can be energized and generate an alternating magnetic field. When the switch 57 is in the off state, the first wire segment 51 and the second wire segment 54 in each turn of the coil 5 are disconnected electrically, and part of the functional line 6 is used as a gate signal line or a data signal line to transmit an electrical signal to control the deflection of the liquid crystal molecules 41, thereby displaying a picture.
[0096] The embodiment of the present application provides a liquid crystal display panel 10, which includes a first substrate 1, a second substrate 2, a liquid crystal layer 4 and a coil 5. The second substrate 2 is arranged opposite to the first substrate 1; the first substrate 1 and the second substrate 2 are fixedly connected by a sealant 3, and the first substrate 1, the second substrate 2 and the sealant 3 are surrounded to form a receiving cavity. The liquid crystal layer 4 is arranged in the receiving cavity; the liquid crystal layer 4 includes a plurality of liquid crystal molecules 41; the coil 5 is arranged around the liquid crystal layer 4; the coil 5 can generate a magnetic field to heat the liquid crystal molecules 41 when powered on. The coil 5 is arranged around the axial direction of the liquid crystal display panel 10; the axial direction is parallel to the liquid crystal display panel 10. By arranging the coil 5 on the liquid crystal display panel 10, when the liquid crystal display panel 10 is used in a low temperature environment, the coil 5 can be powered to generate an alternating magnetic field, thereby heating the liquid crystal molecules 41 using the principle of electromagnetic induction heating, reducing the viscosity of the liquid crystal molecules 41, allowing the liquid crystal molecules 41 to rotate normally, improving the response speed of the liquid crystal display panel 10, avoiding the phenomenon of smearing and color dragging on the liquid crystal display panel 10, and effectively improving the display effect of the liquid crystal display panel 10. In addition, the coil 5 is arranged around the liquid crystal layer 4 so that the liquid crystal layer 4 is at the center of the coil 5 with a larger magnetic field strength, which can effectively increase the heating rate of the liquid crystal molecules 41 and further improve the phenomenon of smearing and color dragging.
[0097] See also Fig. 9 , Fig. 9 A schematic diagram of a module of a display device provided in an embodiment of the present application; the present application also provides a display device, which is used to display images. The display device can avoid the phenomenon of smearing and color dragging on the liquid crystal display panel 10, and effectively improve the display effect of the liquid crystal display panel 10. It can also effectively increase the heating rate of the liquid crystal molecules 41, and further improve the phenomenon of smearing and color dragging. The display device may include a liquid crystal display panel 10, a control unit 20, and a driving chip 40.
[0098] The liquid crystal display panel 10 is the liquid crystal display panel 10 involved in any of the above embodiments.
[0099] The control unit 20 is electrically connected to the coil 5 of the liquid crystal display panel 10 and is used to control whether to supply power to the coil 5 so as to control whether the coil 5 generates a magnetic field.
[0100] In a specific embodiment, the display device may further include a temperature sensor 30 for detecting the temperature of the liquid crystal display panel 10, or directly for detecting the ambient temperature. Specifically, the temperature sensor 30 is electrically connected to one end of the control unit 20, and the control unit 20 controls whether to energize the coil 5 according to the acquired temperature parameters. It can be understood that when the temperature is less than or equal to the preset temperature, the control unit 20 can energize the coil 5 to heat the liquid crystal molecules 41; when the temperature is greater than the preset temperature, the control unit 20 will not energize the coil 5. Specifically, the preset temperature can be the temperature of the liquid crystal freezing point, such as -20°C.
[0101] One end of the driver chip 40 is electrically connected to the driver circuit layer of the liquid crystal display panel 10, and is used to transmit a driving signal to the driver circuit layer and control the liquid crystal display panel 10 to switch between the display frame and the black frame. It can be understood by those skilled in the art that when the liquid crystal display panel 10 displays a dynamic image, due to the long response time of the liquid crystal molecules 41, the image of the previous frame still remains in the next frame, resulting in blurring in the fast-moving image, resulting in image overlap and blur. By adopting the black insertion technology, a black frame is inserted between two display frames to make the image of the previous frame disappear, thereby reducing residual images and motion blur.
[0102] The other end of the driving chip 40 is electrically connected to the control unit 20, and is used to transmit a heating signal to the control unit 20 and enable the control unit 20 to energize the coil 5. By electrically connecting the driving chip 40 to the driving circuit layer and the control unit 20, respectively, the driving chip 40 can control the working state of the coil 5 according to the display state of the liquid crystal display panel 10.
[0103] Among them, in response to the driving chip 40 controlling the liquid crystal display panel 10 to be in a black frame, the control unit 20 energizes the coil 5, so that when the liquid crystal display panel 10 is in the black frame, the coil 5 can generate a magnetic field to heat the liquid crystal molecules 41; in response to the driving chip 40 controlling the liquid crystal display panel 10 to be in a display frame, the control unit 20 stops energizing the coil 5 to avoid the coil 5 interfering with the normal display image of the liquid crystal display panel 10 after being energized.
[0104] See also Fig.10 , Fig.10A module schematic diagram of a display device provided for another embodiment of the present application; in a specific embodiment, if in the liquid crystal display panel 10, part of the functional line 6 serves as the first conductor segment 51 of the coil 5, that is, a switch 57 is provided on the first connecting segment 53 and the second connecting segment 56 of the coil 5, then the control unit 20 can also be electrically connected to the switch 57 of the coil 5, for controlling the switch 57 to be in a conductive state or an open state, so as to control whether the first connecting segment 53 and the second connecting segment 56 are conductive, thereby controlling whether the coil 5 can be energized and generate a magnetic field.
[0105] Specifically, in response to the driving chip 40 controlling the liquid crystal display panel 10 to be in a black frame, the control unit 20 controls the switch 57 to be in a conduction state, so that the first connection segment 53 and the second connection segment 56 of the coil 5 are in a conducting state. At this time, part of the functional line 6 connected to the first connection segment 53 and the second connection segment 56 is connected as the first wire segment 51 and the second wire segment 54 to form the coil 5, and is energized to generate a magnetic field to heat the liquid crystal molecules 41.
[0106] In response to the driving chip 40 controlling the liquid crystal display panel 10 to be in a display frame, the control unit 20 controls the switch 57 to be in an open circuit, so that the first connection segment 53 and the second connection segment 56 are in a disconnected state. At this time, part of the functional lines 6 connected to the first connection segment 53 and the second connection segment 56 are still used as data lines or gate scanning lines, and cooperate with the remaining part of the functional lines 6 to control the deflection of the liquid crystal molecules 41 to display the picture.
