With the increasing progress of science and technology, the demand of users for the flat display panel, which is not satisfied with the conventional flat display panel, and the demand for the curved display panel, that is, the curved screen, is gradually increased and becomes strict. The existing curved screen is easy to generate display quality problems such as black clusters, smear, broken bright spots and the like in the processing process, so that the yield is low, and the cost of the product is increased.
In view of the above, the present invention provides a display panel, please refer to fig. 1 to 3, which illustrate an embodiment of the display panel according to the present invention.
Referring to fig. 1 to 2, a display panel 1 according to the present invention includes a display section 1a, where the display section 1a includes a first substrate (refer to an array substrate 100), a liquid crystal layer 200, and a second substrate (refer to a color film substrate 300) stacked in sequence along a first direction; the liquid crystal layer 200 includes a plurality of first liquid crystal molecules 210 disposed close to the first substrate and a plurality of second liquid crystal molecules 220 disposed close to the second substrate, and the plurality of first liquid crystal molecules 210 and the plurality of second liquid crystal molecules 220 are disposed in a one-to-one correspondence along the first direction; the pretilt angle of the first liquid crystal molecules 210 is smaller than the pretilt angle of the second liquid crystal molecules 220, so that after the display segment 1a is bent to be curved in the first direction, the first liquid crystal molecules 210 and the corresponding second liquid crystal molecules 220 are tilted in the same direction.
In the technical solution provided by the present invention, when the display section 1a is bent toward the first direction, the degree of bending of the second substrate is greater than the degree of bending of the first substrate, and therefore, by setting the pretilt angle of the first liquid crystal molecules 210 to be smaller than the pretilt angle of the second liquid crystal molecules 220, the tilt misalignment formed between the first liquid crystal molecules 210 and the second liquid crystal molecules 220 after bending can be compensated, so that the generation of dark clusters in the display section 1a can be avoided, and the uniformity of the brightness of the display panel 1 is facilitated.
The first direction is not limited to the use orientation of the display panel 1, and is only used to describe the relative positional relationship of the components of the display panel 1. Therefore, in practical applications, the first direction may be embodied as any desired direction without limitation.
It is understood that the display section 1a has at least two states, one is a first state before bending and the other is a second state after bending, but for the convenience of understanding, in the following embodiments, the display section 1a is in the first state unless otherwise specified, and of course, this does not mean that the following features are not provided when the display section 1a is in the second state.
The display section 1a may be disposed to belong to a part of the whole panel surface of the display panel 1, that is, in the display panel 1, only the display section 1a is bent during the processing, and the rest of the display section may be kept straight or subjected to other required deformation processing; in this way, the display section 1a may be provided in one of the display panels 1, or may be provided in plural of the display panels 1, and when the display panel 1 is provided in plural, the plural display sections 1a may be distributed on the display panel 1 according to a preset setting. Of course, the display section 1a may also be disposed as the whole panel surface of the display panel 1, and the whole display panel 1 is bent and formed in the processing process. In the following embodiments, the display section 1a is provided as the entire surface of the display panel 1.
The first substrate, the liquid crystal layer 200, and the second substrate are sequentially stacked along the first direction, wherein the first substrate and the second substrate are substantially parallel and disposed opposite to each other. Specifically, if the first liquid crystal molecules 210 are taken as an example, the first liquid crystal molecules 210 are distributed along a plane where the first substrate is located, and may be uniformly distributed and arranged in any arrangement manner, for example, the first liquid crystal molecules 210 are respectively arranged in an array along the length direction and the width direction of the first substrate.
The plurality of first liquid crystal molecules 210 may be disposed to have the same pretilt angle. Of course, in other embodiments, the first liquid crystal molecules 210 may be disposed in the plurality of first liquid crystal molecules 210 according to the bending condition of the first substrate, where the pretilt angles of at least some of the first liquid crystal molecules 210 are different, and the difference is adapted to the bending condition of the first substrate at the position, for example, when the bending radian of the first substrate is gradually changed, the pretilt angles of the corresponding first liquid crystal molecules 210 are also correspondingly gradually changed.
Note that, the fact that the display section 1a is curved toward the first direction means that the display section 1a gradually protrudes toward the first direction from the edge of the display section 1a to the center of the display section 1 a. Based on this, taking the first liquid crystal molecules 210 as an example, every two first liquid crystal molecules 210 distributed on two opposite sides of the center of the display section 1a and at an equal distance among the plurality of first liquid crystal molecules 210 are disposed approximately symmetrically with respect to the center of the display section 1 a.
When the display segment 1a is bent in the first direction, the bending degree of the second substrate is greater than the bending degree of the first substrate, and therefore, in order to compensate for the difference in the bending degrees, the pretilt angle of the first liquid crystal molecules 210 is set smaller than the pretilt angle of the second liquid crystal molecules 220, and the difference in the pretilt angles is related to the difference in the bending degrees, so that the first liquid crystal molecules 210 and the corresponding second liquid crystal molecules 220 can be ensured to be tilted in the same direction after being bent, and therefore, the display effect at the misaligned position can be prevented from being uneven, and the display quality of the display panel 1 can be reduced. The first liquid crystal molecules 210 and the corresponding second liquid crystal molecules 220 are tilted in the same direction, which is embodied to make orthographic projections of the first liquid crystal molecules 210 and the second liquid crystal molecules 220 on the first substrate or the second substrate at the positions substantially coincide.
It can be understood that, in practical applications, if the difference between the pretilt angle of the first liquid crystal molecules 210 and the pretilt angle of the second liquid crystal molecules 220 is set to be larger or smaller, it is easy to cause that after the bending molding, the orthographic projections of the first liquid crystal molecules 210 and the second liquid crystal molecules 220 on the first substrate at the positions are only partially overlapped, and there is still an interleaving. Therefore, the difference between the pretilt angle of the first liquid crystal molecules 210 and the pretilt angle of the second liquid crystal molecules 220 needs to be set within a suitable range, and in this embodiment, the difference is not less than 1.2 ° and not more than 2.2 °. Further, the angle difference may be set to 1.5 °, which has a better compensation effect.
Based on the above embodiment, the pretilt angle of the first liquid crystal molecules 210 may be further set to 87 ° to 88 °; alternatively, the pretilt angle of the second liquid crystal molecules 220 is 89 ° to 90 °, so that the pretilt angle of the first liquid crystal molecules 210 and the pretilt angle of the second liquid crystal molecules 220 are closer to 90 °, and the display effect of the display panel 1 is ensured.
Of course, there are various ways to realize the difference between the pretilt angles of the first liquid crystal molecules 210 and the second liquid crystal molecules 220, for example, by adjusting or changing the alignment processes of the first liquid crystal molecules 210 and the second liquid crystal molecules 220, and in this embodiment, the display segment 1a further includes a first alignment film 410 disposed between the first substrate and the liquid crystal layer 200, and a second alignment film 420 disposed between the second substrate and the liquid crystal layer 200; the material of the first alignment film 410 is different from the material of the second alignment film 420. By differentiating the materials of the first alignment film 410 and the second alignment film 420, the first liquid crystal molecules 210 and the second liquid crystal molecules 220 are substantially the same in the manufacturing process of the liquid crystal layer 200, thereby avoiding the increase of the manufacturing complexity of the display segment 1 a.
In a specific application, one of the first substrate and the second substrate is an array substrate 100, and the other is a color filter substrate 300. It can be understood that, in the display panel 1, a direction from the array substrate 100 to the color filter substrate 300 is generally a light emitting direction, and based on this, when the first substrate is configured as the array substrate 100 and the second substrate is configured as the color filter substrate 300, the first direction is the light emitting direction; on the contrary, when the first substrate is the color filter substrate 300 and the second substrate is the array substrate 100, the first direction is the reverse direction of the light emitting direction. For convenience of understanding, in the following embodiments, the first substrate is set as the array substrate 100, and the second substrate is set as the color filter substrate 300.
Based on the above, referring to fig. 3, in an embodiment, the array substrate 100 includes a first substrate base 110, a first metal layer 120, a semiconductor layer 130, a second metal layer 140, a first passivation layer 150, a color resistance layer 160, a second passivation layer 170, and a first conductive layer 180, which are sequentially disposed.
Specifically, the first substrate 110 is a glass substrate; the first metal layer 120 is disposed on the first substrate 110, and may be configured to include a gate region of a thin film transistor; the second metal layer 140 includes drain and source regions of a thin film transistor. The semiconductor layer 130 includes other members, such as a gate insulating layer, an active layer, etc., disposed between the first metal layer 120 and the second metal layer 140. The first passivation layer 150 is used to separate the second metal layer 140 from the color-resist layer 160, and the second passivation layer 170 is used to separate the color-resist layer 160 from the first conductive layer 180; the color resistance layer 160 is used for forming color resistance; the first conductive layer 180 is, for example, transparent conductive glass and includes a pixel electrode. The color resistance layer 160 is disposed on the array substrate 100, so that the problem of small vertical distance between the data transmission line and the pixel electrode is solved, the parasitic capacitance is reduced, and the driving cost is reduced.
Further, in an embodiment, the array substrate 100 is provided with a via hole, and the via hole penetrates from the side where the first conductive layer 180 is located to the second metal layer 140. The via hole is used to electrically connect the first conductive layer 180 and the second metal layer 140; the through holes can be arranged in any number, shape, size and position according to actual needs, and are not described in detail herein. By such arrangement, the aperture opening ratio of the display panel 1 is improved, so that the penetration rate is improved, the backlight brightness and the energy consumption are reduced, and the purpose of reducing the cost can be achieved.
Next, in an embodiment, the display section 1a further includes a main spacer 191 and an auxiliary spacer 192, and the main spacer 191 and the auxiliary spacer 192 are disposed on the array substrate 100 at intervals; specifically, the array substrate 100 may be configured to include a display section and a non-display section disposed around the display section, the main spacer 191 is disposed corresponding to the color resist layer 160 in the display section, and the auxiliary spacer 192 is disposed corresponding to the color resist layer 160 in the non-display section. The main spacers 191 and the auxiliary spacers 192 are disposed on the array substrate 100, so that the main spacers 191 and the auxiliary spacers 192 can be effectively prevented from being deviated due to bending, and poor display can be prevented.
Wherein the height difference between the main spacer 191 and the auxiliary spacer 192 is not less than 0.35 μm and not more than 0.5 μm with respect to the first substrate 110. The absolute heights of both the main spacer 191 and the auxiliary spacer 192 are set to be substantially the same; in order to adapt to different heights of corresponding areas of the main spacers 191 and the auxiliary spacers 192 on the array substrate 100, the main spacers 191 and the auxiliary spacers 192 are arranged to have different heights relative to the first substrate 110, and have a height difference, and the height difference is set within 0.35-0.5 μm, so that the display panel 1 is better supported, and the whole display section 1a has better elastic buffering when external force acts on the array substrate 100.
In addition, in an embodiment, one of the materials of the first metal layer 120 and the second metal layer 140 is aluminum, and the other is copper. Further optionally, the first metal layer 120 is made of a copper material, and the second metal layer 140 is made of an aluminum material, which is beneficial to reducing the cost.
