Description
Technical Field
The present invention relates to liquid crystal display technology, and more particularly, to a liquid crystal display device and a method of fabricating the same.
Background
Thin Film Transistor Liquid Crystal Display (TFT-LCD) technology has become the mainstream technology of Liquid Crystal Display at present. At present, several modes such as TN (Twisted Nematic), PVA (polyvinyl alcohol), IPS (In-Plane Switching), AD-SDS (Advanced-super dimensional Switching), etc. have been developed for the TFT-LCD display mode, and the pixel structure, the driving principle, and the display effect thereof are long. The AD-SDS is a short name of Advanced-Super-Dimensional Switching technology (Advanced-Super-Dimensional Switching), and forms a multidimensional electric field through a parallel electric field generated by the edge of a pixel electrode in the same plane and a longitudinal electric field generated between the pixel electrode layer and a common electrode layer, so that all oriented liquid crystal molecules between the pixel electrodes and right above the electrodes in a liquid crystal box can generate rotation conversion, thereby improving the working efficiency of the liquid crystal in a planar orientation system and increasing the light transmission efficiency. The advanced super-dimensional field switching technology can improve the TFT-LCD picture quality and has the advantages of high transmittance, wide viewing angle, high aperture opening ratio, low chromatic aberration, low response time, no extrusion ripple (Push Mura) and the like. The AD-SDS display technology can have a wide viewing angle of 170 degrees or more by its specific structure and driving principle, and exhibits an excellent display effect.
The cross-sectional structure and the on-off display principle of a single sub-pixel display area of an AD-SDS mode liquid crystal display device of the related art are shown in fig. 1a and 1b, and an array substrate 100 in the single sub-pixel display area is composed of a lower substrate 101, a first electrode 102, a passivation layer 103, a second electrode 104, and an alignment layer 105; the color film substrate 200 in the single sub-pixel display area is composed of an upper substrate 201, a color resin adhesive 202 and an orientation layer 203; the liquid crystal 301 is filled between the array substrate 100 and the color film substrate 200, and the liquid crystal molecules 301 are arranged in parallel up and down; the lower polarizer 302 and the upper polarizer 303 are respectively attached to the back surfaces of the array substrate 100 and the color filter substrate 200.
The inventor of the present invention found that, in the AD-SDS liquid crystal display device, under the action of no electric field, after light passes through the lower polarizer 302, the polarization direction of the light is consistent with that of the lower polarizer 302, and then the light passes through the array substrate 100, because the liquid crystal 301 is arranged in parallel, the polarization state of the light after passing through the liquid crystal 301 is not changed, and the lower polarizer 302 and the upper polarizer 303 are vertically arranged, so the light cannot pass through the upper polarizer 303, and at this time, the liquid crystal panel is in a dark state, as shown in fig. 1 a. When an electric field is applied, due to the action of the electric field between the first electrode 102 and the second electrode 104, the liquid crystal 301 is twisted, the polarization state of the light passing through the liquid crystal molecules is changed, and the light can just pass through the upper polarizer 303 vertically arranged with respect to the lower polarizer 302 after passing through the lower polarizer 302, so that the light can pass through the entire liquid crystal cell, and is in a bright state at this time, as shown in fig. 1 b. The AD-SDS mode liquid crystal display requires a high driving voltage to achieve a bright state, and in the bright state, a severe color shift phenomenon occurs at different viewing angles due to a phase retardation effect of a liquid crystal cell.
At present, if color cast is to be reduced, the phase retardation compensation film in the polarizer needs to perform phase compensation on the liquid crystal cell, so as to achieve the purpose of reducing color cast, but this method greatly increases the cost, and when the thickness of the phase retardation compensation film in the polarizer is not matched with that of the liquid crystal cell, the improvement effect is not ideal.

Detailed Description
The embodiment of the invention provides an AD-SDS (analog-digital data System) liquid crystal display device, a manufacturing method and a display device, wherein an orientation layer is only arranged in one of an array substrate and a color film substrate, so that the control on the direction of liquid crystals is reduced, the liquid crystals are easier to distort under the action of an electric field, the driving voltage is further reduced, and simultaneously, due to the phase self-compensation effect of the liquid crystals in a box in a bright state, the colors seen at each visual angle are basically consistent, so that the color cast phenomenon is reduced, and a better display effect is obtained.
The following technical solution is explained with reference to specific examples:
the first embodiment,
As shown in fig. 2a, the AD-SDS liquid crystal display device provided in the embodiment of the present invention includes:
the liquid crystal display panel comprises an array substrate 100, a color film substrate 200, a liquid crystal 301 filled between the array substrate 100 and the color film substrate 200, a lower polarizer 302 arranged outside the array substrate 100, and an upper polarizer 303 arranged outside the color film substrate 200 and perpendicular to the polarization direction of the lower polarizer 302, wherein a multi-dimensional electric field can be formed between the array substrate 100 and the color film substrate 200, and the multi-dimensional electric field can be a transverse electric field, a longitudinal electric field, or electric fields in other directions according to actual needs, wherein:
the array substrate 100 includes: a lower substrate 101, a first electrode 102, a passivation layer 103, a second electrode 104, and an alignment layer 105, wherein:
a first electrode 102 is disposed on the upper surface of the lower substrate 101;
a passivation layer 103 is disposed on an upper surface of the first electrode 102;
the second electrode 104 is disposed on the passivation layer 103;
the orientation layer 105 covers the second electrode 104 and the exposed passivation layer 103, and the upper surface of the orientation layer 105 is rubbed at a preset angle;
the color filter substrate 200 includes: an upper substrate 201 and a color resin 202, wherein the color resin 202 is disposed on the lower surface of the upper substrate 201.
Since the alignment layer 105 is only provided on the array substrate 100 and the alignment layer is not provided on the color filter substrate 200, the alignment layer 105 on the array substrate 100 alone has a binding effect on the liquid crystal between the array substrate 100 and the color filter substrate 200.
Wherein the liquid crystal molecules are arranged according to a rubbing angle, which is preferably 1 to 180 degrees.
When no electric field is applied, as shown in fig. 2a, after the light passes through the lower polarizer 302, the polarization direction is consistent with that of the lower polarizer 302, and then the light passes through the array substrate 100, since the liquid crystal 301 is arranged in parallel up and down according to the rubbing direction of the alignment layer 105, the polarization state of the light after passing through the liquid crystal 301 is not changed, and the lower polarizer 302 and the upper polarizer 303 are vertically arranged, the light cannot pass through the upper polarizer 303, and at this time, the liquid crystal panel is in a dark state.
When an electric field is applied, as shown in fig. 2b, due to the electric field between the first electrode 102 and the second electrode 104, the liquid crystal 301 is twisted, the polarization state of the light passing through the liquid crystal molecules is changed, and the light can just pass through the upper polarizer 303 vertically arranged with respect to the lower polarizer 302 after passing through the lower polarizer 302, so that the light can pass through the entire liquid crystal cell, and is in a bright state at this time.
Because the orientation layer is not arranged on the color film substrate 200, the constraint on the liquid crystal 301 is reduced, so when the liquid crystal screen is required to be in a bright state, the required driving voltage is reduced, meanwhile, because the constraint of the liquid crystal 301 is reduced, the phase self-compensation effect of the liquid crystal in the box in the bright state is enhanced, the colors seen at each visual angle are basically consistent, the color cast phenomenon is reduced, and a better display effect is obtained.
In this embodiment, the upper substrate 101 and the lower substrate 201 may specifically use glass substrates, the first electrode 102 and the second electrode 104 may both use transparent electrodes, specifically Indium Tin Oxide (ITO) electrodes, and the color resin glue 202 may specifically use color red, green, and blue resins.
Example II,
In this embodiment, the array substrate includes an alignment layer, the color filter substrate does not include an alignment layer, and in order to further reduce the driving voltage and obtain a better display effect, the filled liquid crystal is a twisted nematic liquid crystal, the twist angle is 90 degrees, and the pitch is matched with the box thickness of the liquid crystal display device.
As shown in fig. 3a, an AD-SDS liquid crystal display device provided in an embodiment of the present invention includes:
the liquid crystal display panel comprises an array substrate 100, a color film substrate 200, a liquid crystal 301 filled between the array substrate 100 and the color film substrate 200, a lower polarizer 302 arranged outside the array substrate 100, and an upper polarizer 303 arranged outside the color film substrate 200 and perpendicular to the polarization direction of the lower polarizer 302, wherein a multi-dimensional electric field can be formed between the array substrate 100 and the color film substrate 200, and the multi-dimensional electric field can be a transverse electric field, a longitudinal electric field, or electric fields in other directions according to actual needs, wherein:
the array substrate 100 includes: a lower substrate 101, a first electrode 102, a passivation layer 103, a second electrode 104, and an alignment layer 105, wherein:
a first electrode 102 is disposed on the upper surface of the lower substrate 101;
a passivation layer 103 is disposed on an upper surface of the first electrode 102;
the second electrode 104 is disposed on the passivation layer 103;
the orientation layer 105 covers the second electrode 104 and the exposed passivation layer 103, and the upper surface of the orientation layer 105 is rubbed at a preset angle;
the color filter substrate 200 includes: an upper substrate 201 and a color resin 202, wherein the color resin 202 is disposed on the lower surface of the upper substrate 201.
The liquid crystal filled between the array substrate 100 and the color film substrate 200 is a twisted nematic liquid crystal, and the twist angle is 90 degrees.
Since the alignment layer 105 is only provided on the array substrate 100 and the alignment layer is not provided on the color filter substrate 200, the alignment layer 105 on the array substrate 100 alone has a binding effect on the liquid crystal between the array substrate 100 and the color filter substrate 200.
Wherein the liquid crystal molecules are arranged according to a rubbing angle, which is preferably 1 to 180 degrees.
When no electric field is applied, as shown in fig. 3a, after light passes through the lower polarizer 302, the polarization direction is consistent with that of the lower polarizer 302, and then the light passes through the array substrate 100, the liquid crystals 301 are arranged in parallel according to the friction direction of the alignment layer 105, and since the liquid crystals 301 twist nematic liquid crystals, the liquid crystals are twisted from the array substrate to the color film substrate, the twist angle is 90 degrees, the polarization state of the light after passing through the liquid crystals 301 changes, and since the lower polarizer 302 and the upper polarizer 303 are vertically arranged, the light can just pass through the upper polarizer 303 after passing through the lower polarizer 302 and through the change of the polarization state, so that the light can pass through the whole liquid crystal cell, and at this time, the liquid crystal screen is in a bright state. Because of the self-compensation function of the phase of the twisted liquid crystal in the box, the colors seen under each visual angle are consistent, the color cast phenomenon is eliminated, and a better display effect is obtained.
When an electric field is applied, as shown in fig. 3b, the liquid crystal 301 is distorted due to the electric field between the first electrode 102 and the second electrode 104, the polarization state of the light passing through the liquid crystal molecules is not changed, the light cannot pass through the upper polarizer 303 vertically disposed to the lower polarizer 302, and the liquid crystal panel is in a dark state. Since the color filter substrate 200 is not provided with the alignment layer, the constraint on the liquid crystal 301 is reduced, and thus, when the liquid crystal screen is required to be changed into a dark state, the required driving voltage is reduced.
In addition, since the liquid crystal used in this embodiment is a twisted nematic liquid crystal and the driving voltage required to eliminate the twist of the twisted nematic liquid crystal is smaller than that of a twisted parallel arrangement liquid crystal, the driving voltage is further reduced, and the electric energy is saved.
In this embodiment, the upper substrate 101 and the lower substrate 201 may also use glass substrates, the first electrode 102 and the second electrode 104 may both use transparent electrodes, specifically, indium tin oxide ITO electrodes, and the color resin glue 202 may specifically use color red, green, and blue resins.
Example III,
As shown in fig. 4a, the AD-SDS liquid crystal display device provided in the embodiment of the present invention includes:
the liquid crystal display panel comprises an array substrate 100, a color film substrate 200, a liquid crystal 301 filled between the array substrate 100 and the color film substrate 200, a lower polarizer 302 arranged outside the array substrate 100, and an upper polarizer 303 arranged outside the color film substrate 200 and perpendicular to the polarization direction of the lower polarizer 302, wherein a multi-dimensional electric field can be formed between the array substrate 100 and the color film substrate 200, and the multi-dimensional electric field can be a transverse electric field, a longitudinal electric field, or electric fields in other directions according to actual needs, wherein:
the array substrate 100 includes: a lower substrate 101, a first electrode 102, a passivation layer 103, and a second electrode 104, wherein:
a first electrode 102 is disposed on the upper surface of the lower substrate 101;
a passivation layer 103 is disposed on an upper surface of the first electrode 102;
the second electrode 104 is disposed on the passivation layer 103;
the color filter substrate 200 includes: an upper substrate 201, a color resin adhesive 202 and an orientation layer 203, wherein the color resin adhesive 202 is arranged on the lower surface of the upper substrate 201;
the lower surface of the alignment layer 105 is rubbed at a predetermined angle by covering the lower surface of the color resin paste 202 with the alignment layer 105.
Since the alignment layer 203 is only provided on the color filter substrate 200 and the alignment layer is not provided on the array substrate 100, the alignment layer 203 on the color filter substrate 200 only has a binding effect on the liquid crystal between the array substrate 100 and the color filter substrate 200.
Wherein the liquid crystal molecules are arranged according to a rubbing angle, which is preferably 1 to 180 degrees.
When no electric field is applied, as shown in fig. 4a, after the light passes through the lower polarizer 302, the polarization direction is consistent with that of the lower polarizer 302, and then the light passes through the array substrate 100, since the liquid crystal 301 is arranged in parallel up and down according to the rubbing direction of the alignment layer 203, the polarization state of the light after passing through the liquid crystal 301 is not changed, and the lower polarizer 302 and the upper polarizer 303 are vertically placed, the light cannot pass through the upper polarizer 303, and at this time, the liquid crystal panel is in a dark state.
When an electric field is applied, as shown in fig. 4b, due to the electric field between the first electrode 102 and the second electrode 104, the liquid crystal 301 is twisted, the polarization state of the light passing through the liquid crystal molecules is changed, and the light can just pass through the upper polarizer 303 vertically arranged with respect to the lower polarizer 302 after passing through the lower polarizer 302, so that the light can pass through the entire liquid crystal cell, and is in a bright state at this time.
Because the array substrate 100 is not provided with the orientation layer, the constraint on the liquid crystal 301 is reduced, so when the liquid crystal screen is required to be in a bright state, the required driving voltage is reduced, meanwhile, because the constraint on the liquid crystal 301 is reduced, the phase self-compensation effect of the liquid crystal in the box in the bright state is enhanced, the colors seen at each visual angle are basically consistent, the color cast phenomenon is reduced, and a better display effect is obtained.
In this embodiment, the upper substrate 101 and the lower substrate 201 may specifically use glass substrates, the first electrode 102 and the second electrode 104 may both use transparent electrodes, specifically Indium Tin Oxide (ITO) electrodes, and the color resin glue 202 may specifically use color red, green, and blue resins.
Example four,
In this embodiment, the array substrate does not include an alignment layer, the color film substrate includes an alignment layer, and in order to further reduce the driving voltage and obtain a better display effect, the filled liquid crystal is a twisted nematic liquid crystal, the twist angle is 90 degrees, and the pitch is matched with the thickness of the liquid crystal display device box in an opposite direction.
As shown in fig. 5a, an AD-SDS liquid crystal display device provided in an embodiment of the present invention includes:
the liquid crystal display panel comprises an array substrate 100, a color film substrate 200, a liquid crystal 301 filled between the array substrate 100 and the color film substrate 200, a lower polarizer 302 arranged outside the array substrate 100, and an upper polarizer 303 arranged outside the color film substrate 200 and perpendicular to the polarization direction of the lower polarizer 302, wherein a multi-dimensional electric field can be formed between the array substrate 100 and the color film substrate 200, and the multi-dimensional electric field can be a transverse electric field, a longitudinal electric field, or electric fields in other directions according to actual needs, wherein:
the array substrate 100 includes: a lower substrate 101, a first electrode 102, a passivation layer 103, and a second electrode 104, wherein:
a first electrode 102 is disposed on the upper surface of the lower substrate 101;
a passivation layer 103 is disposed on an upper surface of the first electrode 102;
the second electrode 104 is disposed on the passivation layer 103;
the color filter substrate 200 includes: an upper substrate 201, a color resin adhesive 202 and an orientation layer 203, wherein the color resin adhesive 202 is arranged on the lower surface of the upper substrate 201;
the alignment layer 105 covers the lower surface of the color resin paste 202, and the lower surface of the alignment layer 105 is rubbed at a predetermined angle.
The liquid crystal filled between the array substrate 100 and the color film substrate 200 is a twisted nematic liquid crystal, and the twist angle is 90 degrees.
Since the alignment layer 203 is only provided on the color filter substrate 200 and the alignment layer is not provided on the array substrate 100, the alignment layer 203 on the color filter substrate 200 only has a binding effect on the liquid crystal between the array substrate 100 and the color filter substrate 200.
Wherein the liquid crystal molecules are arranged according to a rubbing angle, which is preferably 1 to 180 degrees.
When no electric field is applied, as shown in fig. 5a, after light passes through the lower polarizer 302, the polarization direction is consistent with that of the lower polarizer 302, and then the light passes through the array substrate 100, the liquid crystals 301 are arranged in parallel according to the friction direction of the alignment layer 105, and since the liquid crystals 301 twist nematic liquid crystals, the liquid crystals are twisted from the color film substrate to the array substrate, the twist angle is 90 degrees, the polarization state of the light after passing through the liquid crystals 301 changes, and the lower polarizer 302 and the upper polarizer 303 are vertically arranged, the light can just pass through the upper polarizer 303 after passing through the lower polarizer 302 and through the change of the polarization state, so the light can pass through the whole liquid crystal box, and the liquid crystal screen is in a bright state. Because of the self-compensation function of the phase of the twisted liquid crystal in the box, the colors seen under each visual angle are consistent, the color cast phenomenon is eliminated, and a better display effect is obtained.
When an electric field is applied, as shown in fig. 5b, due to the electric field between the first electrode 102 and the second electrode 104, the liquid crystal 301 is twisted, the polarization state of the light passing through the liquid crystal molecules is not changed, the light cannot pass through the upper polarizer 303 vertically disposed to the lower polarizer 302, and the liquid crystal panel is in a dark state. Since the array substrate 100 is not provided with the alignment layer, the confinement of the liquid crystal 301 is reduced, and thus, when the liquid crystal panel is required to be changed to a dark state, the required driving voltage is reduced.
In addition, since the liquid crystal used in this embodiment is a twisted nematic liquid crystal and the driving voltage required to eliminate the twist of the twisted nematic liquid crystal is smaller than that of a twisted parallel arrangement liquid crystal, the driving voltage is further reduced, and the electric energy is saved.
In this embodiment, the upper substrate 101 and the lower substrate 201 may specifically use glass substrates, the first electrode 102 and the second electrode 104 may both use transparent electrodes, specifically Indium Tin Oxide (ITO) electrodes, and the color resin glue 202 may specifically use color red, green, and blue resins.

And step S604, manufacturing the AD-SDS liquid crystal display device by using the array substrate and the color film substrate.
Because only the alignment layer is coated on the array substrate, the driving voltage is reduced, the color cast phenomenon is reduced, the process steps are reduced, the controllability and the reliability of the manufacturing process are improved, and the yield and the performance of the product are improved.
As shown in fig. 7, step S604 specifically includes:
