Technical Field

[0001] The embodiments of the present application relate to the field of display technology, and in particular to a liquid crystal display device. Background Art

[0002] A display device is a common electronic output device that can convert electronic files into graphics and display the images through a screen. A liquid crystal display device is a common display device, including a backlight module and a liquid crystal layer. The backlight module emits light toward the liquid crystal layer, thereby being able to display images by adjusting the deflection of liquid crystals in the liquid crystal layer. However, the light emission angle of the liquid crystal display device is small, and the display effect of the liquid crystal display device is poor. Summary of the invention

[0003] The embodiments of the present application provide a liquid crystal display device, which can solve the technical problem that the light emitting angle of the liquid crystal module is small and the display effect of the liquid crystal display device is poor.

[0004] In a first aspect, an embodiment of the present application provides a liquid crystal display device, comprising:

[0005] Backlight module and display panel;

[0006] The display panel comprises:

[0007] A pixel electrode layer is arranged on the light-emitting side of the backlight module; the pixel electrode layer comprises a plurality of first electrodes and a plurality of second electrodes;

[0008] A liquid crystal layer is arranged on a side of the pixel electrode layer away from the backlight module; the liquid crystal layer comprises a plurality of first liquid crystal units and a plurality of second liquid crystal units, the first liquid crystal units are arranged on the first electrode, and the second liquid crystal units are arranged on the second electrode;

[0009] A common electrode layer, disposed on a side of the liquid crystal layer away from the pixel electrode layer, the common electrode layer covering the plurality of first liquid crystal units and the plurality of second liquid crystal units;

[0010] A polarizer, disposed on a side of the common electrode layer away from the liquid crystal layer;

[0011] The adjustment film layer comprises a main body and a plurality of adjustment structures, wherein the plurality of adjustment structures are arranged on a surface of the polarizer away from the common electrode layer, and along the light emitting direction of the backlight module, each of the adjustment structures corresponds to at least one of the second liquid crystal units, and the plurality of adjustment structures are arranged in a staggered manner with the plurality of first liquid crystal units; the main body covers the surfaces of the plurality of adjustment structures away from the common electrode layer, and the refractive index of the main body is different from the refractive index of the adjustment structures;

[0012] A driving chip is electrically connected to the plurality of first electrodes and the plurality of second electrodes, wherein the driving chip provides a first voltage to the plurality of first electrodes and provides a second voltage to the plurality of second electrodes.

[0013] In the liquid crystal display device of the embodiment of the present application, when the liquid crystal display device is in a wide viewing angle mode, the driving chip provides a first voltage to the first electrode, and the driving chip provides a second voltage to the second electrode, and the first voltage may be equal to the second voltage; the backlight module emits part of the light through the plurality of first liquid crystal units, and the backlight module emits the rest of the light through the plurality of second liquid crystal units, the light emitted through the plurality of second liquid crystal units passes through the polarizer, and is emitted through the adjustment structure and the main body, and because the refractive index of the adjustment structure is different from the refractive index of the main body, the light is refracted when passing through the main body from the adjustment structure, thereby increasing the light emission angle of the liquid crystal display device to improve the display effect of the liquid crystal display device;

[0014] When the liquid crystal display device is in a high contrast mode, the driving chip provides a first voltage to the first electrode, and the driving chip provides a second voltage to the second electrode, and the second voltage is less than the first voltage, so that the backlight module emits part of the light through the multiple first liquid crystal units, and the backlight module emits the rest of the light through the multiple second liquid crystal units. The light emitted through the multiple second liquid crystal units passes through the polarizer and is emitted through the adjustment structure and the main body. Since the second voltage is less than the first voltage, the angle of the light emitted through the multiple second liquid crystal units is different from that of the light emitted through the multiple first liquid crystal units, so that the self-adjusting structure refracts less light when passing through the main body, and the angle of refraction of the light through the self-adjusting structure when passing through the main body is smaller, thereby improving the contrast of the liquid crystal display device and further improving the display effect of the liquid crystal display device.

[0015] In some embodiments of the present application, the plurality of first liquid crystal units form a plurality of first liquid crystal unit rows arranged along a first direction, and each of the first liquid crystal unit rows extends along a second direction;

[0016] The plurality of second liquid crystal units form a plurality of second liquid crystal unit rows arranged along the first direction, and each of the second liquid crystal unit rows extends along the second direction;

[0017] Among the plurality of first liquid crystal unit rows and the plurality of second liquid crystal unit rows, along the first direction, the second liquid crystal unit row is accommodated between at least two adjacent first liquid crystal unit rows; and / or, the first liquid crystal unit row is accommodated between at least two adjacent second liquid crystal unit rows.

[0018] In this way, the plurality of first liquid crystal units are formed into a plurality of first liquid crystal unit rows, and the plurality of second liquid crystal units are formed into a plurality of second liquid crystal unit rows, and a second liquid crystal unit row is accommodated between at least two adjacent first liquid crystal unit rows; and / or a first liquid crystal unit row is accommodated between at least two adjacent second liquid crystal unit rows;

[0019] When the liquid crystal display device is viewed along the thickness direction of the backlight module, several second liquid crystal unit rows and the corresponding adjustment film layers simultaneously refract light, thereby reducing the possibility of bright spots or dark spots appearing in the liquid crystal display device and improving the display effect of the liquid crystal display device.

[0020] In some embodiments of the present application, the plurality of adjustment structures form a plurality of adjustment structure rows arranged along the first direction, and each of the adjustment structure rows extends along the second direction;

[0021] Along the light emitting direction of the backlight module, each of the adjustment structure rows corresponds to a second liquid crystal unit row disposed between two adjacent first liquid crystal unit rows.

[0022] In this way, by forming a plurality of adjustment structures into a plurality of adjustment structure rows, the molding process of the plurality of adjustment structures can be made more convenient; and, by correspondingly arranging the adjustment structure rows to the second liquid crystal unit rows, the accuracy of the mutual correspondence between the plurality of adjustment structures and the plurality of second liquid crystal units can be improved, thereby increasing the possibility that the light passing through the second liquid crystal unit can pass through the corresponding adjustment structure.

[0023] In some embodiments of the present application, the refractive index of the main body is greater than the refractive index of the adjustment structure;

[0024] In the adjustment structure row, the adjustment structures are arranged in sequence and spaced apart along the second direction, and each of the adjustment structures has a hemispherical surface, and the hemispherical surface is arranged to protrude away from the polarizer;

[0025] Alternatively, in the adjustment structure row, the adjustment structures are connected in sequence, and the adjustment structure row has an arc-shaped surface, and the arc-shaped surface is protruded away from the polarizer.

[0026] In this way, the adjustment structures can be arranged in sequence at intervals, and each adjustment structure has a hemispherical surface, which is convexly arranged away from the polarizer, so that a convex lens structure is formed by the adjustment structure, thereby further improving the divergence effect of the adjustment structure on light and increasing the display effect of the liquid crystal display device;

[0027] Alternatively, the adjustment structures are connected in sequence, and the adjustment structure row has a curved surface, which is protruded away from the polarizer, so that the molding process of the adjustment structure is more convenient, and the adjustment structure row can form a convex lens structure, thereby further improving the divergence effect of the adjustment structure row on light and increasing the display effect of the liquid crystal display device.

[0028] In some embodiments of the present application, the refractive index of the main body is less than the refractive index of the adjustment structure;

[0029] In the adjustment structure row, the adjustment structures are arranged in sequence and spaced apart along the second direction, and each of the adjustment structures has a hemispherical surface, and the hemispherical surface is convexly arranged toward the polarizer;

[0030] Alternatively, in the adjustment structure row, the adjustment structures are connected in sequence, and the adjustment structure row has an arc-shaped surface, and the arc-shaped surface is convexly arranged toward the polarizer.

[0031] In this way, the adjustment structures can be arranged in sequence at intervals, and each adjustment structure has a hemispherical surface, which is convexly arranged toward the polarizer, so that a concave lens structure is formed by the adjustment structure, thereby further improving the divergence effect of the adjustment structure on light and increasing the display effect of the liquid crystal display device;

[0032] Alternatively, the adjustment structures are connected in sequence, and the adjustment structure row has a curved surface, which is protruded away from the polarizer, so that the molding process of the adjustment structure is more convenient, and the adjustment structure row can form a concave lens structure, thereby further improving the divergence effect of the adjustment structure row on light and increasing the display effect of the liquid crystal display device.

[0033] In some embodiments of the present application, the plurality of first liquid crystal unit rows and the plurality of second liquid crystal unit rows are alternately arranged in sequence along the first direction, and the plurality of adjustment structure rows are arranged in one-to-one correspondence with the plurality of second liquid crystal rows;

[0034] Along the light emitting direction of the backlight module, the orthographic projection of each adjustment structure row on the liquid crystal layer is located between two adjacent first liquid crystal unit rows, and the orthographic projection of each adjustment structure row on the liquid crystal layer covers the corresponding second liquid crystal unit.

[0035] In this way, several adjustment structure rows and several second liquid crystal rows are arranged in a one-to-one correspondence, and the orthographic projection of each adjustment structure row on the liquid crystal layer is located between two adjacent first liquid crystal unit rows, and the orthographic projection of each adjustment structure row on the liquid crystal layer covers the corresponding second liquid crystal unit, thereby reducing the possibility that the adjustment structure row is arranged in correspondence with the first liquid crystal unit row, and can increase the accuracy of the mutual correspondence between the adjustment structure row and the second liquid crystal unit, and increase the possibility that the light passing through the second liquid crystal unit row can pass through the corresponding adjustment structure row.

[0036] In some embodiments of the present application, a plurality of support members are further included. Along the light emitting direction of the backlight module, a first end of the support member is connected to the backlight module, and a second end of the support member is connected to the common electrode layer.

[0037] In this arrangement, the first end of the support member is connected to the backlight module, and the second end of the support member is connected to the common electrode layer, so that the support member can provide certain support to the multiple first liquid crystal units and the multiple second liquid crystal units, thereby reducing the possibility of damage to the liquid crystal layer and ensuring the display effect of the liquid crystal display device.

[0038] In some embodiments of the present application, a filter layer is further included, and along the light emitting direction of the backlight module, the filter layer is arranged between the common electrode layer and the polarizer;

[0039] The filter layer includes a baffle and a plurality of filter elements, and along the light emitting direction of the backlight module, each filter element is correspondingly arranged on one of the first liquid crystal units or one of the second liquid crystal units;

[0040] The retaining wall is filled between adjacent filters, and in a plane perpendicular to the light emitting direction of the backlight module, the retaining wall is used to separate adjacent first liquid crystal units or adjacent second liquid crystal units; or, the retaining wall is used to separate adjacent first liquid crystal units and second liquid crystal units.

[0041] With such arrangement, the filter element can play a certain filtering role on light passing through the corresponding first liquid crystal unit or the corresponding second liquid crystal unit, so as to improve the display effect of the liquid crystal display device;

[0042] The retaining wall is used to separate adjacent first liquid crystal units or adjacent second liquid crystal units; or, the retaining wall is used to separate adjacent first liquid crystal units and second liquid crystal units, so that the possibility of mutual interference between the first liquid crystal units and the second liquid crystal units can be reduced by the retaining wall, so that the light emitted by the backlight module passes through the corresponding first liquid crystal units and the second liquid crystal units more accurately, thereby improving the display effect of the liquid crystal display device;

[0043] Furthermore, the light passing through the first liquid crystal unit and the second liquid crystal unit usually has a component parallel to the direction of the backlight module, so that the brightness of the light component along the thickness direction of the backlight module is relatively low, and the light component parallel to the direction of the backlight module is easy to interfere with the light on the side, thereby causing side light leakage and affecting the contrast of the liquid crystal display device; by setting a baffle wall to block the light component parallel to the direction of the backlight module, the possibility of side light leakage in the liquid crystal display device is reduced, the brightness of the liquid crystal display device is increased, and the contrast of the liquid crystal display device is improved.

[0044] In a second aspect, an embodiment of the present application provides a liquid crystal display device,

[0045] It includes a driving chip, and a backlight module, a pixel electrode layer, a liquid crystal layer, a common electrode layer, a polarizer and an adjustment film layer which are stacked in sequence;

[0046] The pixel electrode layer includes a plurality of first electrodes and a plurality of second electrodes, wherein the first electrodes receive a first voltage from the driving chip, and the second electrodes receive a second voltage from the driving chip; the liquid crystal layer includes a plurality of first liquid crystal cells and a plurality of second liquid crystal cells, wherein the first liquid crystal cells are arranged at the first electrodes, and the second liquid crystal cells are arranged at the second electrodes;

[0047] The common electrode layer is used in conjunction with the first electrode to adjust the deflection of the liquid crystal molecules in the first liquid crystal unit; the common electrode layer is used in conjunction with the second electrode to adjust the deflection of the liquid crystal molecules in the second liquid crystal unit; the adjustment film layer is used to diffuse the light passing through the second liquid crystal unit;

[0048] When the liquid crystal display device is in a first state, the second voltage is equal to the first voltage, the deflection angle of the liquid crystal in the second liquid crystal unit is equal to the deflection angle of the liquid crystal molecules in the first liquid crystal unit, and the adjustment film layer diverges the light passing through the second liquid crystal unit;

[0049] When the liquid crystal display device is in a second state, the second voltage is lower than the first voltage, and a deflection angle of liquid crystal in the second liquid crystal unit is lower than a deflection angle of liquid crystal molecules in the first liquid crystal unit.

[0050] In the liquid crystal display device of the embodiment of the present application, when the liquid crystal display device is in a wide viewing angle mode, the liquid crystal display device is in a first state, the driving chip provides a first voltage to the first electrode, the driving chip provides a second voltage to the second electrode, and the first voltage is equal to the second voltage; the backlight module emits part of the light through the plurality of first liquid crystal units, and the backlight module emits the rest of the light through the plurality of second liquid crystal units, the light emitted through the plurality of second liquid crystal units passes through the adjustment film layer, and is emitted after being diverged by the adjustment film layer, so that the light emitting angle of the liquid crystal display device can be increased by the adjustment film layer to improve the display effect of the liquid crystal display device;

[0051] When the liquid crystal display device is in a high contrast mode, the liquid crystal display device is in a second state, the driving chip provides a first voltage to the first electrode, and the driving chip provides a second voltage to the second electrode, and the second voltage is less than the first voltage, so that the backlight module emits part of the light through the multiple first liquid crystal units, and the backlight module emits the rest of the light through the multiple second liquid crystal units, and the light emitted through the multiple second liquid crystal units passes through the adjustment film layer and is emitted through the adjustment film layer. Since the second voltage is less than the first voltage, the angle of the light emitted through the multiple second liquid crystal units is different from that of the light emitted through the multiple first liquid crystal units, so that the self-adjusting structure refracts less light when passing through the main body, and the angle of refraction when the light passes through the adjustment film layer is smaller, thereby improving the contrast of the liquid crystal display device, and then improving the display effect of the liquid crystal display device.

[0052] In some embodiments of the present application, when the liquid crystal display device is in the second state, the ratio of the second voltage to the first voltage is greater than or equal to 0.25 and less than or equal to 0.5.

[0053] In this way, the ratio of the second voltage to the first voltage is greater than or equal to 0.25 and less than or equal to 0.5, so that the control process of the driving chip providing the first voltage to the first electrode and the driving chip providing the second voltage to the second electrode is more convenient, and the deflection angle of the second liquid crystal unit is more accurate, thereby reducing the angle of refraction that occurs when the light passing through the second liquid crystal unit passes through the adjustment film layer.

[0080] As described in the background technology, in the related art, the liquid crystal display device includes a backlight module and a liquid crystal layer. The backlight module emits light toward the liquid crystal layer, so that the image can be displayed by adjusting the deflection angle of the liquid crystal in the liquid crystal layer. Since the light emission direction of the backlight module is usually parallel to the thickness direction of the backlight module, and the direction of the light emitted by the backlight module after passing through the liquid crystal layer is still parallel to the thickness direction of the backlight module, although the contrast of the liquid crystal display device is high, the effect of viewing the liquid crystal display device from the front is better, but the light emission angle of the liquid crystal display device is small, the light emission effect of the liquid crystal display device toward the side is poor, and when the liquid crystal display device is observed from the side, the display effect of the liquid crystal display device is poor.

[0081] In view of this, in the liquid crystal display device of the embodiment of the present application, when the liquid crystal display device is in a wide viewing angle mode, the driving chip provides a first voltage to the first electrode, and the driving chip provides a second voltage to the second electrode, and the first voltage is equal to the second voltage; the backlight module emits part of the light through the plurality of first liquid crystal units, and the backlight module emits the rest of the light through the plurality of second liquid crystal units, the light emitted through the plurality of second liquid crystal units passes through the polarizer, and is emitted through the adjustment structure and the main body, and because the refractive index of the adjustment structure is different from the refractive index of the main body, the light is refracted when passing through the main body from the adjustment structure, thereby increasing the light emission angle of the liquid crystal display device to improve the display effect of the liquid crystal display device;

[0082] When the liquid crystal display device is in a high contrast mode, the driving chip provides a first voltage to the first electrode, and the driving chip provides a second voltage to the second electrode, and the second voltage is less than the first voltage, so that the backlight module emits part of the light through the multiple first liquid crystal units, and the backlight module emits the rest of the light through the multiple second liquid crystal units. The light emitted through the multiple second liquid crystal units passes through the polarizer and is emitted through the adjustment structure and the main body. Since the second voltage is less than the first voltage, the angle of the light emitted through the multiple second liquid crystal units is different from that of the light emitted through the multiple first liquid crystal units, so that the angle of refraction of the light when the self-adjusting structure passes through the main body is smaller, thereby improving the contrast of the liquid crystal display device and further improving the display effect of the liquid crystal display device.

[0089] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0090] Reference Figure 1 An embodiment of the present application provides a liquid crystal display device, including a backlight module 100 and a display panel. The backlight module 100 can emit light toward the display panel. Exemplarily, the display panel includes a pixel electrode layer 200, a liquid crystal layer 300, a common electrode layer 400, a polarizer 500 and an adjustment film layer 600 arranged in sequence along a direction away from the backlight module 100; wherein the pixel electrode layer 200 is arranged on the light-emitting side of the backlight module 100 so that the backlight module 100 can emit light toward the pixel electrode layer 200, and the pixel electrode layer 200 includes a plurality of first electrodes 210 and a plurality of second electrodes 220.

[0091] Reference Figure 1 and Figure 2 The liquid crystal layer 300 can be arranged on the side of the pixel electrode layer 200 away from the backlight module 100. The liquid crystal layer 300 includes a plurality of first liquid crystal units 310 and a plurality of second liquid crystal units 320. The first liquid crystal units 310 and the second liquid crystal units 320 each have a plurality of liquid crystal molecules, so that the plurality of first liquid crystal units 310 and the plurality of second liquid crystal units 320 adjust the light passing through the backlight module 100 by deflecting the liquid crystal molecules. The first liquid crystal unit 310 can be correspondingly arranged at the first electrode 210, and each second liquid crystal unit 320 can be correspondingly arranged at the second electrode 220.

[0092] The common electrode layer 400 can be arranged on the side of the liquid crystal layer 300 away from the pixel electrode layer 200, and the common electrode layer 400 can cover a plurality of first liquid crystal units 310 and a plurality of second liquid crystal units 320, so that the common electrode layer 400 cooperates with the first electrode 210 to control the deflection of the liquid crystal molecules in the first liquid crystal unit 310, and the common electrode layer 400 cooperates with the second electrode 220 to control the deflection of the liquid crystal molecules in the second liquid crystal unit 320, thereby adjusting the direction of the light. The polarizer 500 is arranged on the surface of the common electrode layer 400 away from the liquid crystal layer 300 to adjust the light passing through the first liquid crystal unit 310 and the second liquid crystal unit 320.

[0093] Reference Figure 1In some possible embodiments, the adjustment film layer 600 may include a main body 610 and a plurality of adjustment structures 620, wherein the plurality of adjustment structures 620 are disposed on a surface of the polarizer 500 away from the common electrode layer 400, and along the light emitting direction of the backlight module 100, the plurality of adjustment structures 620 are staggered with the plurality of first liquid crystal units 310, and each adjustment structure 620 is correspondingly disposed in at least one second liquid crystal unit 320; the main body 610 covers the surfaces of the plurality of adjustment structures 620 away from the common electrode layer 400, and the refractive index of the main body 610 is different from the refractive index of the adjustment structure 620, so as to adjust the light passing through the second liquid crystal unit 320 through the adjustment film layer 600.

[0094] Exemplarily, part of the light from the backlight module 100 passes through multiple first liquid crystal units 310, and part of the light from the backlight module 100 passes through multiple second liquid crystal units 320; when the light self-adjusting structure 620 of the second liquid crystal unit 320 passes through the main body 610, refraction will occur, causing the light to diverge, so that the propagation direction of the light forms an angle with the thickness direction of the backlight module 100, thereby increasing the light emitting angle of the liquid crystal display device.

[0095] The liquid crystal display device may further include a driving chip 700, which is electrically connected to the plurality of first electrodes 210 and the plurality of second electrodes 220, and provides a first voltage to the plurality of first electrodes 210, and provides a second voltage to the plurality of second electrodes 220, so as to control the deflection angles of the plurality of first liquid crystal units 310 and the deflection angles of the plurality of second liquid crystal units 320 through the driving chip 700.

[0096] It should be noted that the first voltage can be set to a range, or the first voltage can be adjusted according to actual needs. For example, the first voltage can be set according to the image that the liquid crystal display device needs to display. The first voltages received by different first electrodes 210 from the driving chip 700 can be the same, or the first voltages received by different first electrodes 210 from the driving chip 700 can be different, so that the deflection angles of the liquid crystal molecules in different first liquid crystal units 310 can be different.

[0097] The second voltage can be set to a range, and the magnitude of the second voltage can be adjusted according to the magnitude of the first voltage, so that the deflection angle of the liquid crystal molecules of the multiple second liquid crystal units 320 can be different from the deflection angle of the liquid crystal molecules of the multiple first liquid crystal units 310, thereby being used in conjunction with the adjustment film layer 600 to achieve the divergence of light passing through the second liquid crystal unit 320.

[0098] When the number of first electrodes 210 and the number of second electrodes 220 are the same, multiple second electrodes 220 can be set one-to-one with multiple first electrodes 210, or, when the number of second electrodes 220 is less than the number of first electrodes 210, each second electrode 220 can be set corresponding to several first electrodes 210; the second voltage received by the second electrode 220 can be adjusted according to the first voltage received by the corresponding first electrode 210, so that the light passing through the second liquid crystal unit 320 can correspond to the light passing through the first liquid crystal unit 310.

[0099] Reference Figure 1 In some possible implementations, multiple first electrodes 210 and multiple second electrodes 220 can be set in the same layer and the same material. For example, a metal layer can be formed in the backlight module 100, and then part of the metal layer can be removed by etching or the like, so that the first part of the remaining metal layer forms multiple first electrodes 210, and the second part of the remaining metal layer forms multiple second electrodes 220, so that the forming process of the multiple first electrodes 210 and the multiple second electrodes 220 is more convenient.

[0100] Reference Figure 1 and Figure 2 , illustratively, multiple first liquid crystal units 310 and multiple second liquid crystal units 320 can be arranged in the same layer and the same material, and multiple first liquid crystal units 310 and multiple second liquid crystal units 320 can be arranged in multiple rows and columns, and multiple second liquid crystal units 320 can be set in a one-to-one correspondence with multiple first liquid crystal units 310 to make the correspondence between the second liquid crystal units 320 and the first liquid crystal units 310 more accurate.

[0101] Alternatively, the plurality of first liquid crystal units 310 may be formed along the first direction (ie Figure 2 The plurality of first liquid crystal unit rows 330 are arranged along the second direction (ie, the y direction in FIG. 1 ), and each of the first liquid crystal unit rows 330 is arranged along the second direction (ie, the y direction in FIG. 1 ). Figure 2 The plurality of second liquid crystal units 320 may form a plurality of second liquid crystal unit rows 340 arranged along the first direction, each second liquid crystal unit row 340 may extend along the second direction, the first direction may be perpendicular to the second direction, the first direction may be set to a vertical direction, and the second direction may be set to a horizontal direction, so as to increase the display angle of the liquid crystal display device in the horizontal direction;

[0102] Among the plurality of first liquid crystal cell rows 330 and the plurality of second liquid crystal cell rows 340, along the first direction, a second liquid crystal cell row 340 is accommodated between at least two adjacent first liquid crystal cell rows 330; and / or, a first liquid crystal cell row 330 is accommodated between at least two adjacent second liquid crystal cell rows 340, and the second liquid crystal cell row 340 can be used to correspond to one or more adjacent rows of first liquid crystal cell rows 330.

[0103] For example, in the first direction, several first liquid crystal unit rows 330 and several second liquid crystal unit rows 340 can be arranged alternately in sequence, and each second liquid crystal unit row 340 can be arranged one-to-one with an adjacent first liquid crystal unit row 330, that is, the light passing through the first liquid crystal unit row 330 propagates along the thickness direction of the backlight module 100, and the light passing through the corresponding second liquid crystal unit row 340 can diverge toward the first direction after passing through the adjustment film layer 600.

[0104] When the liquid crystal display device is viewed along the thickness direction of the backlight module 100, relative to the one-to-one arrangement of the second liquid crystal units 320 and the first liquid crystal units 310, several second liquid crystal unit rows 340 and the corresponding adjustment film layer 600 simultaneously realize the refraction of light, so that the deflection angles of two adjacent second liquid crystal units 320 along the first direction are closer, thereby reducing the possibility of bright spots or dark spots appearing in the liquid crystal display device and improving the display effect of the liquid crystal display device.

[0105] In some possible embodiments, the common electrode layer 400 can be arranged on the surface of the liquid crystal layer 300 away from the pixel electrode layer 200, and part of the common electrode layer 400 covers the multiple first liquid crystal units 310, and the part of the common electrode layer 400 covering the multiple first liquid crystal units 310 is arranged opposite to the multiple first electrodes 210 to control the deflection angle of the liquid crystal in the first liquid crystal unit 310; the remaining part of the common electrode layer 400 covers the multiple second liquid crystal units 320, and the part of the common electrode layer 400 covering the multiple second liquid crystal units 320 is arranged opposite to the multiple second electrodes 220 to control the deflection angle of the liquid crystal in the second liquid crystal unit 320.

[0106] Exemplarily, the liquid crystal display device also includes multiple support members 350. Along the thickness direction of the backlight module 100, the first end of the support member 350 is connected to the backlight module 100, and the second end of the support member 350 is connected to the common electrode layer 400, so that the support member 350 can provide certain support for the multiple first liquid crystal units 310 and the multiple second liquid crystal units 310, so as to reduce the possibility of damage to the liquid crystal layer 300 and ensure the display effect of the liquid crystal display device.

[0107] In some possible embodiments, the liquid crystal display device may further include a filter layer 800, which is disposed on a surface of the common electrode layer 400 facing away from the liquid crystal layer 300. The filter layer 800 includes a retaining wall 810 and a plurality of filter elements 820. Along the light emitting direction of the backlight module 100, each filter element 820 is correspondingly disposed on a first liquid crystal unit 310 or a second liquid crystal unit 320. The filter element 820 can play a certain filtering role on light passing through the corresponding first liquid crystal unit 310 or the corresponding second liquid crystal unit 320, so as to improve the display effect of the liquid crystal display device.

[0108] Exemplarily, the baffle wall 810 can be filled between adjacent filters 820, and in a plane perpendicular to the light emitting direction of the backlight module 810, the baffle wall 810 can be used to block the light passing through the adjacent first liquid crystal unit 310 or the light passing through the adjacent second liquid crystal unit 320; alternatively, the baffle wall 810 can also be used to block the light passing through the adjacent first liquid crystal unit 310 and the second liquid crystal unit 320.

[0109] It is easy to understand that the light passing through the first liquid crystal unit 310 and the second liquid crystal unit 320 usually has a component parallel to the direction of the backlight module 100, so that the brightness of the component of the light along the thickness direction of the backlight module 100 is relatively low, and the component of the light parallel to the direction of the backlight module 100 is easy to interfere with the light on the side, resulting in side light leakage, affecting the contrast of the liquid crystal display device.

[0110] The retaining wall 810 is used to block the light passing through the adjacent first liquid crystal unit 310 or the light passing through the adjacent second liquid crystal unit 320; or, the retaining wall 810 is used to block the light passing through the adjacent first liquid crystal unit 310 and the second liquid crystal unit 320, so as to block the component of the light parallel to the direction of the backlight module 100 through the retaining wall 810, reduce the possibility of side light leakage of the liquid crystal display device, increase the brightness of the liquid crystal display device, and improve the contrast of the liquid crystal display device;

[0111] Furthermore, the blocking wall 810 reduces the possibility of mutual interference between the first liquid crystal unit 310 and the second liquid crystal unit 320 , so that the light from the backlight module 100 passes through the corresponding first liquid crystal unit 310 and second liquid crystal unit 320 more accurately.

[0112] Exemplarily, the polarizer 500 can be arranged on the side of the filter layer 800 away from the liquid crystal layer 300, the polarizer 500 can be arranged as a multi-layer structure, and the polarizer 500 can play a certain regulating and filtering role on the light passing through the first liquid crystal unit 310 and the second liquid crystal unit 320, thereby changing the light emission angle of the light passing through the first liquid crystal unit 310 and the second liquid crystal unit 320, and increasing the light emission angle of the liquid crystal display device.

[0113] Reference Figure 4In some possible implementations, in the adjustment film layer 600, the surface of the main body 610 away from the common electrode layer 400 may be arranged parallel to the common electrode layer 400, and the adjustment film layer 600 may be formed on the surface of the polarizer 500 away from the common electrode layer 400. For example, a plurality of adjustment structures 620 may be first formed on the surface of the common electrode layer 400, and then the surface of the plurality of adjustment structures 620 away from the common electrode layer 400 may cover the main body 610, so that the main body 610 and the plurality of adjustment structures 620 form the adjustment film layer 600;

[0114] Alternatively, part of the structure in the polarizer 500 can be reused to form the adjustment film layer 600. For example, the polarizer 500 includes a first part and a second part connected to the first part. The refractive index of the first part or the second part of the polarizer 500 can be changed so that the refractive index of the first part of the polarizer 500 is less than the refractive index of the second part of the polarizer 500, so that the first part of the polarizer 500 forms the adjustment structure 620 and the second part of the polarizer 500 forms the main body 610 to form the adjustment film layer 600.

[0115] Or, refer to Figure 5 , a groove can be formed on the main body 610 by etching or the like, and then a plurality of adjustment structures 620 are formed in the groove, so that the adjustment structure 620 is flush with the surface of the main body 610, so that the main body 610 and the plurality of adjustment structures 620 form an adjustment film layer 600, and then the adjustment film layer 600 is covered on the surface of the common electrode layer 400 away from the liquid crystal layer 300, so that the adjustment structure 620 can be attached to the common electrode layer 400, thereby realizing the preparation of the adjustment film layer 600.

[0116] For example, refer to Figure 6 and Figure 7 , multiple adjustment structures 620 can be arranged in multiple rows and columns. For example, multiple adjustment structures 620 can form several adjustment structure rows 630 arranged along the first direction, and each adjustment structure row 630 extends along the second direction; along the light-emitting direction of the backlight module 100, each adjustment structure row 630 corresponds to a second liquid crystal unit row 340 arranged between two adjacent first liquid crystal unit rows 330, wherein the light-emitting direction of the backlight module 100 can be parallel to the thickness direction of the backlight module 100.

[0117] It is easy to understand that when a second liquid crystal cell row 340 is arranged between two adjacent first liquid crystal cell rows 330, for example, when several first liquid crystal cell rows 330 and several second liquid crystal cell rows 340 are alternately arranged in sequence along the first direction, each adjustment structure row 630 can be used to correspond to one second liquid crystal cell row 340, or, when multiple second liquid crystal cell rows 340 are arranged between two adjacent first liquid crystal cell rows 330, each adjustment structure row 630 can also be used to correspond to multiple second liquid crystal cell rows 340.

[0118] Exemplarily, along the light-emitting direction of the backlight module 100, the orthographic projection of each adjustment structure row 630 on the liquid crystal layer 300 is located between two adjacent first liquid crystal unit rows 330, and the orthographic projection of each adjustment structure row 630 on the liquid crystal layer 300 covers the corresponding second liquid crystal unit 320 to reduce the possibility of light passing through the first liquid crystal unit row 330 passing through the adjustment structure row 630.

[0119] Reference Figure 5 and Figure 6 The refractive index of the main body 610 may be greater than the refractive index of the adjustment structure 620. The adjustment structures 620 may be arranged in sequence along the second direction. Along the light emitting direction of the backlight module 100, each adjustment structure 620 is correspondingly arranged at a second liquid crystal unit 320. Each adjustment structure 620 has a hemispherical surface. The hemispherical surface may be convexly arranged away from the polarizer 500, so as to form a convex lens structure through the adjustment structure 620, thereby further improving the divergence effect of the adjustment structure 620 on light and increasing the display effect of the liquid crystal display device.

[0120] Or, refer to Figure 7 In the adjustment structure row 630, the adjustment structures 620 are connected in sequence, and the adjustment structure row 630 has a curved surface, which is protruded away from the polarizer 500, so that the molding process of the adjustment structure 620 is more convenient, and the adjustment structure row 630 can form a convex lens structure, thereby further improving the divergence effect of the adjustment structure row 630 on light and increasing the display effect of the liquid crystal display device.

[0121] Reference Figure 8 The refractive index of the main body 610 may also be smaller than the refractive index of the adjustment structure 620. The adjustment structures 620 may be arranged in sequence along the second direction. Along the light emitting direction of the backlight module 100, each adjustment structure 620 is correspondingly arranged in a second liquid crystal unit 320. Each adjustment structure 620 has a hemispherical surface, and the hemispherical surface may be convexly arranged toward the polarizer 500, so as to form a concave lens structure through the adjustment structure 620, thereby further improving the divergence effect of the adjustment structure 620 on light and increasing the display effect of the liquid crystal display device.

[0122] Alternatively, in the adjustment structure row 630, the adjustment structures 620 are connected in sequence, and the adjustment structure row 630 has a curved surface, which is protruding toward the polarizer 500, so that the molding process of the adjustment structure 620 is more convenient, and the adjustment structure row 630 can form a concave lens structure, thereby further improving the divergence effect of the adjustment structure row 630 on light and increasing the display effect of the liquid crystal display device.

[0123] It is easy to understand that when the adjustment film layer 600 is formed on the surface of the polarizer 500 away from the common electrode layer 400, at least part of the retaining wall 810 and the adjustment structure 620 are arranged in a staggered manner to reduce the blocking of the light passing through the second liquid crystal unit 320 by the retaining wall 810. In summary, by adopting the above technical solution, the liquid crystal display device can be set to at least a large viewing angle mode and a high contrast mode, wherein, when the liquid crystal display device needs to be viewed from the side, the liquid crystal display device can be set to a large viewing angle mode, and part of the light emitted by the liquid crystal display device diverges toward both sides, so as to form an angle with the thickness direction of the backlight module 100, thereby increasing the light emission angle of the liquid crystal display device;

[0124] Alternatively, when the liquid crystal display device is viewed from the front, the liquid crystal display device can be set to a high contrast mode to reduce the angle at which light emitted by the liquid crystal display device diverges toward both sides, so that the light emitted by the liquid crystal display device is close to the thickness direction of the backlight module 100, thereby improving the front display effect of the liquid crystal display device and increasing the contrast of the liquid crystal display device.

[0125] For example, the driver chip 700 of the liquid crystal display device can determine how large an area of ​​the display scene is displayed in low grayscale through the front-end signal source, and pop up an option to the user so that the user can determine whether the mode is a large viewing angle mode or a high contrast mode. When the user determines that the mode is a large viewing angle mode, the driver chip 700 differentially drives the first electrode 210 and the second electrode 220 by adjusting the magnitude of the first voltage and the second voltage, so that the light passing through the second liquid crystal unit 320 can be diverged through the adjustment film layer 600 to increase the display angle of the liquid crystal display device.

[0126] Reference Fig. 9 and Fig.10 , exemplarily, when the liquid crystal display device is in a wide viewing angle mode, the driving chip 700 provides a first voltage to the first electrode 210, and the driving chip 700 provides a second voltage to the second electrode 220, and the first voltage can be equal to the second voltage, so that the deflection angle of the liquid crystal molecules of the plurality of second liquid crystal units 320 can correspond to the deflection angle of the liquid crystal molecules set in the plurality of first liquid crystal units 310; and the backlight module 100 emits part of the light through the plurality of first liquid crystal units 310, and the backlight module 100 emits the rest of the light through the plurality of second liquid crystal units 320.

[0127] The light emitted by the multiple second liquid crystal units 320 passes through the polarizer 500, and is emitted through the adjustment structure 620 and the main body 610 in turn. Since the refractive index of the adjustment structure 620 is smaller than the refractive index of the main body 610, the light will be refracted when passing through the main body 610 from the adjustment structure 620, so that the light passing through the second liquid crystal unit 320 is diverged through the adjustment film layer 600, thereby increasing the light emission angle of the liquid crystal display device to improve the display effect of the liquid crystal display device.

[0128] Reference Fig.11 and Fig.12 When the liquid crystal display device is in a high contrast mode, the driving chip 700 provides a first voltage to the first electrode 210, and the driving chip 700 provides a second voltage to the second electrode 220, and the second voltage is less than the first voltage, and the ratio of the second voltage to the first voltage can be greater than or equal to 0.25 and less than or equal to 0.5. For example, the ratio of the second voltage to the first voltage can be set to one of 0.25, 0.3, 0.35, 0.4, 0.45 and 0.5, so that the ratio of the first voltage to the second voltage can be preset in the driving chip 700, thereby making the control process of the driving chip 700 outputting the first voltage and the second voltage more convenient.

[0129] The second voltage received by the second electrode 220 is smaller than the first voltage received by the corresponding first electrode 210, the deflection angle of the liquid crystal in the second liquid crystal unit 320 is smaller than the deflection angle of the liquid crystal in the corresponding first liquid crystal unit 310, part of the light from the backlight module 100 passes through the multiple first liquid crystal units 310, and part of the light from the backlight module 100 passes through the multiple second liquid crystal units 320.

[0130] The light emitted by the multiple second liquid crystal units 320 passes through the polarizer 500, and is emitted through the adjustment structure 620 and the main body 610 in sequence. Since the second voltage is lower than the first voltage, the angle of the light passing through the multiple second liquid crystal units 320 is different from that of the light emitted through the multiple first liquid crystal units 310. The component of the light passing through the second liquid crystal units 320 in the thickness direction of the backlight module 100 is smaller than the component of the light emitted through the first liquid crystal units 310 in the thickness direction of the backlight module 100, so that less light is refracted when the self-adjusting structure 620 passes through the main body 610, and the angle of refraction of the light when the self-adjusting structure 620 passes through the main body 610 is smaller, so as to reduce the angle at which the light emitted by the liquid crystal display device diverges toward both sides, thereby improving the contrast of the liquid crystal display device.

[0131] Reference Fig. 9 and Fig.10 , Fig.11 and Fig.12The embodiment of the present application provides a liquid crystal display device, including a driving chip 700, and a backlight module 100, a pixel electrode layer 200, a liquid crystal layer 300, a common electrode layer 400, a polarizer 500 and an adjustment film layer 600 stacked in sequence; the pixel electrode layer 200 includes a plurality of first electrodes 210 and a plurality of second electrodes 220, the first electrodes 210 receive a first voltage from the driving chip 700, and the second electrodes 220 receive a second voltage from the driving chip 700; the liquid crystal layer 300 includes a plurality of first liquid crystal units 310 and a plurality of second liquid crystal units 320, each first liquid crystal unit 310 is correspondingly arranged at the first electrode 210, and each second liquid crystal unit 320 is correspondingly arranged at the second electrode 220.

[0132] The common electrode layer 400 is used in conjunction with the first electrode 210 to adjust the deflection of the liquid crystal in the first liquid crystal unit 310; the common electrode layer 400 is used in conjunction with the second electrode 220 to adjust the deflection of the liquid crystal in the second liquid crystal unit 320; the polarizer 500 can play a certain regulating and filtering role on the light passing through the first liquid crystal unit 310 and the second liquid crystal unit 320, and the regulating film layer 600 is used to diverge the light passing through the second liquid crystal unit 320.

[0133] When the liquid crystal display device is in the first state, the liquid crystal display device is in a wide viewing angle mode, the driving chip 700 provides a first voltage to the first electrode 210, and the driving chip 700 provides a second voltage to the second electrode 220, and the first voltage can be equal to the second voltage; the backlight module 100 emits part of the light through the plurality of first liquid crystal units 310, and the backlight module 100 emits the remaining part of the light through the plurality of second liquid crystal units 320, and the light emitted through the plurality of second liquid crystal units 320 passes through the adjustment film layer 600, and is emitted after being diverged by the adjustment film layer 600, so that the light emitting angle of the liquid crystal display device can be increased by adjusting the film layer 600 to improve the display effect of the liquid crystal display device;

[0134] When the liquid crystal display device is in the second state, the liquid crystal display device is in a high contrast mode, the driving chip 700 provides a first voltage to the first electrode 210, and the driving chip 700 provides a second voltage to the second electrode 220, and the second voltage is less than the first voltage. The ratio of the second voltage to the first voltage can be greater than or equal to 0.25 and less than or equal to 0.5. For example, the ratio of the second voltage to the first voltage can be set to one of 0.25, 0.3, 0.35, 0.4, 0.45 and 0.5.

[0135] The backlight module 100 emits part of the light through the multiple first liquid crystal units 310, and the backlight module 100 emits the rest of the light through the multiple second liquid crystal units 320. The light emitted through the multiple second liquid crystal units 320 passes through the adjustment film layer 600 and is emitted through the adjustment film layer 600. Since the second voltage is lower than the first voltage, the angle of the light emitted through the multiple second liquid crystal units 320 is different from that of the light emitted through the multiple first liquid crystal units 310, so that the angle of refraction of the light when passing through the adjustment film layer 600 is smaller, thereby improving the contrast of the liquid crystal display device, and further improving the display effect of the liquid crystal display device.
