Description

Array substrate and display device

Technical Field

Background

A typical TFT-LCD (Thin Film Transistor-Liquid Crystal Display) includes: the liquid crystal display panel comprises a color film substrate provided with a common electrode and a color filter, an array substrate provided with a thin film transistor and a pixel electrode, and a liquid crystal layer clamped between the color film substrate and the array substrate. TN (twisted Nematic) liquid crystal display devices are the most basic and common display devices in TFT-LCDs, have the advantages of small size, light weight, simple manufacture, high transmittance, low cost, and the like, and are widely used in products such as televisions, notebook computers, and the like.

For the TN type liquid crystal display device, a layer of orientation film is respectively arranged on the contact surface of the array substrate and the liquid crystal, and the contact surface of the color film substrate and the liquid crystal, the angle difference of the two layers of orientation films is 90 degrees, and under the combined action of the surface anchoring forces of the two layers of orientation films, liquid crystal molecules form a 90-degree twisted alignment structure between the array substrate and the color film substrate. If a certain voltage is applied between the common electrode and the pixel electrode, the liquid crystal molecules are affected by the electric field generated by the voltage, and the arrangement direction of the liquid crystal molecules tends to be parallel to the electric field, i.e. the liquid crystal molecules are arranged perpendicular to the array substrate and the color film substrate, and the twisted alignment structure of the liquid crystal molecules disappears. After the voltage is removed, the liquid crystal molecules will return to the original twisted alignment structure. Therefore, by controlling the magnitude of the applied voltage, the degree of twist of the liquid crystal molecules can be controlled, and thus the brightness of the light transmitted through the liquid crystal can be controlled.

As is well known, the TN display device has a problem of narrow viewing angle (simply referred to as viewing angle), and if the viewing angle exceeds the viewing angle range, the contrast is low and the color is distorted. Similarly, in a VA (Vertical Alignment) type display device, the same problem exists.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

An embodiment of the utility model provides an array substrate, it is shown with reference to fig. 1, this array substrate includes: the data line 21 and the gate line 23 are arranged in a crossing manner, and the sub-pixel defined by the adjacent data line 21 and the adjacent gate line 23 comprises a first sub-pixel 12 and a second sub-pixel 11, and the distance between the pixel electrode 24 of the first sub-pixel 12 and the data line of the first sub-pixel is d 1; the distance between the pixel electrode 25 of the second sub-pixel 11 and the data line of the second sub-pixel is d2, wherein d1 is greater than the first threshold, d2 is less than the second threshold, and the first threshold is greater than or equal to the second threshold.

The distance between the pixel electrode and the data line in this embodiment refers to the distance between a certain pixel electrode and the data line driving the pixel electrode, and specifically, as shown in fig. 2, in the first sub-pixel 12, the distance between the pixel electrode 24 and the data line 21 is d1, the start end of the first sub-pixel is the left edge of the pixel electrode 24, and the tail end of the first sub-pixel is the data line 21 located on the left side of the pixel electrode 24. Similarly, in the second sub-pixel 11, the distance between the pixel electrode 25 and the data line 21 is d2, and d2 is the distance between the left edge of the pixel electrode 25 and the data line 21.

The embodiment of the present invention defines the first threshold as the influence of the potential of the data line is negligibly small as long as the distance from the data line to the pixel electrode is greater than the first threshold; the second threshold is defined as a lateral electric field generated in an edge area of the pixel electrode due to the potential of the data line as long as the distance from the data line to the pixel electrode is less than the second threshold.

Optionally, the area of the pixel electrode 24 of the first sub-pixel 12 is not equal to the area of the pixel electrode 25 of the second sub-pixel 11. Further alternatively, the area of the pixel electrode 24 of the first sub-pixel 12 is smaller than the area of the pixel electrode 25 of the second sub-pixel 11, so that the distance d1 from the pixel electrode 24 to the data line 21 is greater than the distance d2 from the pixel electrode 25 to the data line 21.

The array substrate provided by the embodiment is provided with two sub-pixels, wherein the distances between the pixel electrode 24 of the first sub-pixel 12 and the data line 21 of the corresponding sub-pixel are both d1, d1 is greater than a first threshold, and as can be known from the definition of the first threshold, the electric field generated by the potential of the data line has no influence or negligible influence on the driving electric field between the pixel electrode and the common electrode, so that the color representation is more real; the distances between the pixel electrode 25 of the second sub-pixel 11 and the data line 21 of the corresponding sub-pixel are d2, d2 is smaller than the second threshold, and it can be known from the definition of the second threshold that, at this time, under the influence of the potential of the data line, a lateral electric field is generated between the pixel electrode 25 and the data line, and the lateral electric field can affect the liquid crystal molecules, so that the image under a large horizontal viewing angle can obtain a better contrast, thereby increasing the viewing angle of the TN (Twisted Nematic) mode in the horizontal direction. In fact, there is a driving electric field between the pixel electrode 25 and the common electrode 31, the driving electric field and the transverse electric field are distributed as shown in fig. 3, and the transverse electric field is coupled with the driving electric field to form an electric field distribution as shown in fig. 4, but the effect is the same as that described above.

In the embodiment, the first sub-pixel and the second sub-pixel are adopted to realize a wide viewing angle, and meanwhile, the reality degree of color restoration can be ensured. In particular, the first and second sub-pixels are usually formed into pixels, and then the pixels are arranged in a mixed manner. In one mode, the first sub-pixels form a first type of pixel, the second sub-pixels form a second type of pixel, and the first type of pixel and the second type of pixel are arranged on the substrate in a mixed manner.

Fig. 1 is a schematic diagram showing a specific structure of an array substrate according to this embodiment, two types of pixels are disposed on the array substrate, a first type of pixel 26 includes at least three first sub-pixels 12, a second type of pixel 27 includes at least three second sub-pixels 11, and the first type of pixel 26 and the second type of pixel 27 are arranged on the substrate at intervals.

Specifically, the first pixel 26 is provided with three first sub-pixels 12, wherein the area of the pixel electrode 24 of each first sub-pixel 12 is the same, and the distances between the pixel electrodes 24 and the data lines 21 of the corresponding sub-pixels are d1, specifically, in a first sub-pixel 12, d1 refers to the distance between the left edge of the pixel electrode 24 and the sub-pixel data line 21, d1 is greater than a first threshold, and it can be known from the definition of the first threshold that the electric field generated by the potential of the data line has no influence on the driving electric field between the pixel electrode and the common electrode, so that the color representation is more realistic.

The second pixel 27 is also provided with three identical second sub-pixels 11, wherein the area of the pixel electrode 25 of each second sub-pixel 11 is the same, and the distances between the pixel electrode 25 and the data line 21 of the corresponding sub-pixel are all d2, similarly, specifically, for one second sub-pixel 11, d2 is the distance between the left edge of the pixel electrode 25 and the data line 21 of the sub-pixel 11, and d2 is smaller than a second threshold, as can be known from the definition of the second threshold, at this time, a lateral electric field is generated between the pixel electrode 25 and the data line under the influence of the potential of the data line, and the lateral electric field can affect the liquid crystal molecules, so that a better contrast ratio of an image under a horizontal large viewing angle can be obtained, and the viewing angle of a TN (Twisted Nematic) mode in the horizontal direction can be increased.

The second sub-pixel 11 in this embodiment can also be as shown in fig. 5, when the boundary of the pixel electrode 25 of the second sub-pixel extends outward beyond the limited area of the two adjacent data lines, the boundary overlaps with the data line 21 of the second sub-pixel, and at this time, the distance d2 between the left edge of the pixel electrode 25 and the data line 21 can be understood as a negative value, and at this time, the condition smaller than the second threshold is also satisfied, and still due to the influence of the data line potential, a lateral electric field is generated at the edge of the pixel electrode 25, and further the deflection of the liquid crystal molecules in the corresponding area is influenced, so that the problem of narrow viewing angle of the conventional liquid crystal display can be solved.

It should be noted that the distance d1 between the pixel electrode of the first sub-pixel and the data line of the first sub-pixel, and the distances d2, d1 between the pixel electrode of the second sub-pixel and the data line of the second sub-pixel are larger than d2, which should be measured under the same condition, so that it is comparable, especially when the pixel electrode is irregular. For example, points on the pixel electrodes 24 and 25 where the lengths of adjacent gate lines are the same may be selected as respective measurement points, and then the distances to the data lines may be measured.

In the embodiment, the first and second pixels are adopted to realize a wide viewing angle and ensure the fidelity of color restoration. Preferably, the first pixels and the second pixels are arranged at intervals, and can be alternately arranged in the horizontal direction (parallel to the gate lines) shown in the figure or in the vertical direction (parallel to the data lines) shown in the figure, but preferably, the first pixels and the second pixels are alternately arranged in the horizontal direction and the vertical direction, so that the brightness is more uniform than that of a mixed arrangement, and the display effect is better.

It should be noted that, in the above description of the present embodiment, the pixel includes three sub-pixels as an example, but this is because the liquid crystal display device generally adopts a color mixing scheme of three primary colors of red, green and blue, and therefore, each pixel includes three sub-pixels of red, green and blue, but actually, the color mixing scheme includes not only red, yellow and blue (R/G/B), but also other color mixing schemes of red, green, blue and white (R/G/B/W), and therefore, in a specific implementation, the number of sub-pixels in each pixel is not limited.

In addition, in the embodiment, the sub-pixels are divided into two types, and in specific implementation, a person skilled in the art can also divide the sub-pixels into three, four or even more types according to needs, and the distances between the pixel electrode and the data line in each type of pixel are different.

The above-described scheme is applicable to a TN (Twisted Nematic) type liquid crystal display and also to a VA (Vertical Alignment) type liquid crystal display.

Example 2

An embodiment of the present invention provides an array substrate, as shown in fig. 6, fig. 7 and fig. 8, the difference from the first embodiment is that the first sub-pixel 12 and the second sub-pixel 11 form the first pixel sub-unit and the second pixel sub-unit in the following manner in this embodiment: in the first pixel sub-unit 46, the first sub-pixel 12 is located below the second sub-pixel 11 in the direction parallel to the data line, and in the second pixel sub-unit 49, the first sub-pixel 12 is located above the second sub-pixel 11 in the direction parallel to the data line 21; and, the first subpixel 12 and the second subpixel 11 in the same pixel sub-unit are driven by the same data line 21 and the same gate line 23. Then, a pixel is formed using the first pixel sub-unit 46 and the second pixel sub-unit 49.

The second pixel sub-unit 49 can be seen as the first pixel sub-unit 46 is turned upside down, and the first and second words are used only for convenience of distinction when describing the arrangement of the pixel sub-units (the first pixel sub-unit and the second pixel sub-unit in a general term) later.

In this embodiment, each pixel subunit includes: the first sub-pixel 12 and the second sub-pixel 11, and in the first sub-pixel 12, the distance between the first pixel electrode 24 and the data line 21 of the sub-pixel is d1, and d1 is greater than a first threshold, and as defined by the threshold, the influence of the potential of the data line can be ignored, and the reality of color expression is ensured; in the second sub-pixel 11, the distance between the second pixel electrode 25 and the data line 21 is d2, d2 is smaller than the second threshold, and it can be known from the definition of the second threshold that the lateral electric field is generated at the edge of the second pixel electrode 25 under the influence of the data line potential, which affects the driving electric field between the pixel electrode 25 and the common electrode 31, and further the deflection of the liquid crystal molecules at the edge of the pixel region is affected, so that the problem of narrow viewing angle of the conventional liquid crystal display can be solved. Because each pixel sub-unit comprises the first sub-pixel 12 and the second sub-pixel 11, each pixel sub-unit can give consideration to the wide viewing angle and the reality degree of color expression, and the whole display effect of the display is better.

Fig. 7 shows a schematic structural diagram of a first pixel subunit 46, where d1 refers to the distance from the left edge of the first pixel electrode 24 to the data line 21 opposite to the edge (i.e. the data line 21 of the sub-pixel); d2 refers to the distance between the left edge of the second pixel electrode 25 and the data line 21 opposite to the edge.

In the present embodiment, the first sub-pixel 12 and the second sub-pixel 11 are first utilized to form the first sub-pixel unit and the second sub-pixel unit, and then the first sub-pixel unit and the second sub-pixel unit are arranged to form the pixel.

The first specific implementation manner of this embodiment is as follows: the first pixel sub-unit 46 and the second pixel sub-unit 49 described above form two kinds of pixels in the following manner: the first type of pixel 47 comprises at least three first pixel sub-units 46, and the second type of pixel 48 comprises at least three second pixel sub-units 49.

As shown in fig. 6, the structure of an array substrate according to the present embodiment includes two kinds of pixels disposed on the array substrate, and the two kinds of pixels are arranged in a mixed manner; the first pixel 47 comprises three first pixel sub-units 46, and the second pixel 48 comprises at least three second pixel sub-units 49. In the first pixel 47, the first pixel electrodes 24 of the first pixel sub-units 46 are all located below the second pixel electrodes 25 in the direction parallel to the data lines 21; in the second pixel 48, the first pixel electrodes 24 of the second pixel sub-units 49 are all located above the second pixel electrodes 25 along the direction parallel to the data lines 21, i.e. the second pixel 48 is in the form of a first pixel 47 which is upside down.

The above and below do not refer to a positional relationship on the layer structure, but are merely a concept of relative orientation, which is used for indicating the relative positions of the first pixel electrode 24 and the second pixel electrode 25 in the sub-pixel in the plan view, and is not used for limitation, and the embodiment is understood with reference to the orientation shown in fig. 6.

Specifically, as shown in fig. 6, the first pixel 47 includes a plurality of first pixel sub-units 46 having the same structure, and the first pixel sub-units 46 are combined in such a manner that the first pixel electrodes 24 are located below the second pixel electrodes 25; the second pixel 48 includes a plurality of second pixel sub-units 49 with the same structure, and the second pixel sub-units 49 are combined in a manner that the first pixel electrodes 24 are located above the second pixel electrodes 25. Then, the first and second pixels 47 and 48 are mixedly arranged on the array substrate.

Because the distance between the first pixel electrode 24 and the data line 21 is d1, the color reproduction is not affected by the potential of the data line 21, and the color reproduction can be guaranteed; the distance between the second pixel electrode 25 and the data line is d2, the viewing angle is wide under the influence of the potential of the data line 21, and each pixel sub-unit comprises the first pixel electrode 24 and the second pixel electrode 25, so that the wide viewing angle and the color representation can be both realized by each pixel sub-unit.

In the present embodiment, two kinds of pixels composed of pixel sub-units are disposed on the array substrate, each pixel sub-unit can consider the fidelity of the wide viewing angle and the color expression, the second type of pixel 48 is the form of the first type of pixel 47 being upside down, and then the first type of pixel 47 and the second type of pixel 48 are arranged on the array substrate in a mixed manner to compensate for the difference in the brightness distribution between the first type of pixel 47 and the second type of pixel 48, so that the brightness is more uniform and the display effect is better. Wherein "above" and "below" are the same as "above" and "below", respectively, in the above explanation.

As shown in fig. 8, a second specific embodiment of this embodiment is shown, in which the first pixel sub-unit and the second pixel sub-unit form a pixel in the following manner: the first pixel sub-unit 46 and the second pixel sub-unit 49 are alternately arranged along the gate line direction to form a pixel 50.

In a direction parallel to the data line 21, the first pixel electrode 24 in the first pixel sub-unit 46 is located below the second pixel electrode 25, and the first pixel electrode 24 in the second pixel sub-unit 49 is located above the second pixel electrode 25. Compared with the first embodiment of the present embodiment, the second pixel electrodes 25 with a large area and the first pixel electrodes 24 with a small area are alternately arranged along the gate line or the data line, so that the combination of the wide viewing angle and the reality of color representation is more perfect, the overall brightness of the liquid crystal display panel is more uniform, and the display effect is better.

The present embodiment further provides a third embodiment, which is different from the first and second embodiments in that in this embodiment, the first pixel sub-unit 46 and the second pixel sub-unit 49 are both provided with: a first thin film transistor for driving the first subpixel 12 and a second thin film transistor for driving the second subpixel 11, which share the same data line 21 and the same gate line 23.

Alternatively, a double-channel thin film transistor 52 may be disposed in each of the first pixel sub-unit 46 and the second pixel sub-unit 49, and specifically, as shown in fig. 6 and 8, two sources of the double-channel thin film transistor 52 are connected to the same data line, a common gate is connected to the same gate line, and two drains are connected to the first sub-pixel 12 and the second sub-pixel 11, respectively.

The first subpixel 12 and the second subpixel 11 may be respectively located at two sides of the common gate line 23, and correspondingly, the first pixel electrode 24 and the second pixel electrode 25 are also respectively located at two sides of the common gate line 23, and of course, the first subpixel 12 and the second subpixel 11 may be disposed at the same side of the common gate line 23 according to practical situations.

In this embodiment, the first pixel sub-units and the second pixel sub-units in each pixel are alternately arranged, each pixel sub-unit can give consideration to both the wide viewing angle and the color representation, and the first thin film transistor and the second thin film transistor (or the double-channel thin film transistor 52) are adopted to respectively drive the first pixel electrode and the second pixel electrode, so that the driving capability is improved, the brightness of the liquid crystal display is more uniform, and the display effect is better.

The foregoing embodiments also include the case similar to fig. 5, where the pixel electrode 25 of the second sub-pixel extends outward beyond the limited area of the two adjacent data lines, and in this case, the lateral electric field is generated between the second pixel electrode 25 and the data line 21 under the influence of the potential of the data line, so as to influence the deflection of the liquid crystal molecules, and thus, the wide viewing angle can be achieved.

In this embodiment, each pixel subunit includes a first pixel electrode 24 and a second pixel electrode 25, the distance between the first pixel electrode 24 and the data line 21 is d1, which is not affected by the potential of the data line, so as to ensure the reality of color representation, the distance between the second pixel electrode 25 and the data line 21 is d2, which is affected by the potential of the data line, so as to achieve a wide viewing angle, and therefore, the reality and the wide viewing angle of color representation can be considered in each pixel subunit.
