The present invention provides an array substrate 10, which is mainly used for a liquid crystal display panel.

In an embodiment of the present invention, referring to fig. 1 to 8, the array substrate 10 includes a data line 110, a scan line 120 and a pixel unit 130, the scan line 120 is perpendicularly intersected with the data line 110, an area enclosed by the scan line 120 and the data line 110 is the pixel unit 130, the pixel unit 130 includes a main trunk 131 and branches 132 respectively disposed at two sides of the main trunk 131, and extension lines of the branches 132 form included angles with the data line 110 and the scan line 120; the stem 131 comprises a main body 131a and a first end 131b connected with the main body 131a, wherein two opposite sides of the first end 131b are provided with a chamfer 1301 and/or a fillet 1302, or the end surface of the first end 131b is an arc surface 1303, and when the end surface of the first end 131b is the arc surface 1303, the arc surface 1303 is smoothly connected with the main body 131 a.

The stem 131 and the branch 132 of the pixel unit 130 are both transparent and conductive, for example, the stem 131 and the branch 132 are both indium tin oxide or indium zinc oxide or amorphous indium tin oxide coated on the array substrate 10. The screen of the display panel corresponding to each pixel unit 130 can display a corresponding color when the pixel electrode is powered on. The layout structure of the pixel electrode can affect the rotation angle of the liquid crystal molecules 30, thereby affecting the color state and brightness on the screen.

The stem 131 in the pixel unit 130 can generally divide the pixel unit 130 into at least two regions, and the corresponding liquid crystal molecules 30 in each of the divided regions need to have the same turn as possible, thereby reducing color difference. According to the technical scheme of the invention, the chamfer 1301 (shown in fig. 2) and/or the fillet 1302 (shown in fig. 3) are/is arranged at the first end 131b of the main body 131 (i.e. the end extending towards the scanning line 120 and/or the data line 110), or the end face of the first end 131b is arranged in the arc surface 1303 (shown in fig. 4), so that the main body 131a of the main body 131 to the first end 131b of the main body 131 can be in the direction from the outer contour of the main body 131 to the first end 131b of the main body 131, and the outer contour of the main body 131 does not have a sharp corner state, thereby reducing the influence of the fringe electric field on the liquid crystal molecules 30 and reducing the probability of disclination of the corresponding liquid crystal molecules 30.

Specifically, one or more chamfer parts 1301 are arranged on two sides of the first end 131b of the trunk 131. The structure in which the plurality of chamfers 1301 are disposed at the first end 131b of the main body 131 means that a secondary chamfering process is performed again at a new corner formed after the first chamfering process is performed on the first end 131b of the main body 131, and so on, and the first end 131b of the main body 131 can realize a multi-chamfering structure. After the first end 131b of the stem 131 is subjected to the chamfering process, the inner angles of the patterns formed by the outer contours of the first end 131b of the stem 131 are all obtuse angles, so that the extension directions of two adjacent surfaces of the first end 131b of the whole stem 131 are prevented from being changed rapidly, the curvature radius of the position is increased, more charges are prevented from being concentrated at the position, and the liquid crystal molecules 30 are prevented from being influenced by the fringe electric field and not being arranged in the preset orientation. It can be understood that, when the number of the chamfers 1301 is larger, the inner angle of the shape formed by the outer contour of the first end 131b of the stem 131 is closer to a flat angle, so that the probability of disclination of the liquid crystal molecules 30 corresponding to the first end 131b is reduced, and the occurrence of more dark fringes due to the influence of the fringe electric field is avoided. Further, in order to better avoid the first end 131b of the trunk 131 from having a sharp corner, in the technical solution of the present invention, the first end 131b of the trunk 131 may be designed with a rounded corner 1302 or the first end 131b of the trunk 131 is in an arc 1303.

Of course, in the technical solution of the present invention, the branch 132 further includes a connecting portion 132a connected to the main portion 131 and a second end 132b extending away from the main portion 131, and two opposite sides of the second end 132b (i.e. the end away from the main portion 131) of the branch 132 may also be provided with a chamfer 1301 (as shown in fig. 5) and/or a fillet 1302 (as shown in fig. 6); or the end surface of the second end 132b is provided with an arc surface 1303 (as shown in fig. 7), and the arc surface 1303 is smoothly connected with the connecting portion 132 a. It will be appreciated that a chamfer 1301 and/or a rounded corner 1302 are provided at the second end 132b of the branch 132; or the second ends 132b of the branches 132 are arranged to be the curved surfaces 1303, the probability of disclination of the liquid crystal molecules 30 corresponding to the ends of the branches 132 can be reduced.

According to the technical scheme of the invention, the first end 131b of the main body 131 and/or the second end 132b of the branch 132 are/is provided with the chamfer 1301, so that the inner angles of the shapes formed by the ends of the main body 131 and/or the branches 132 are obtuse angles, and the extending directions of the two adjacent surfaces of the ends of the main body 131 and/or the branches 132 are approximately the same, so that the curvature radius of the ends is increased, more electric charges are prevented from being concentrated at the positions, the influence of fringe electric fields on the disordered arrangement of liquid crystals can be weakened, and the probability of disclination phenomenon of the liquid crystal molecules 30 at the positions is reduced.

Further, as shown in fig. 1, 2 and 5, when the ends of the trunk 131 and/or the ends of the branches 132 have a chamfer 1301 on each of two opposite sides, the outer contour of the ends of the trunk 131 and/or the ends of the branches 132 is a half-trapezoid structure having an upper base (end face of the ends) and two waists (the half-trapezoid structure refers to only the upper base and the waist in the trapezoid pattern). It can be understood that the included angles between the waist and the upper bottom in the semi-trapezoidal structure are all obtuse angles, which can reduce the effect of the fringe electric field on the liquid crystal molecules 30, thereby reducing the probability of disclination of the liquid crystal molecules 30. Further, two waists of this half trapezium structure can be the same (the waist length of two waists and the contained angle homogeneous phase of two waists and last end are the same), so set up, can be so that the both sides of the terminal of trunk 131 and/or the terminal of branch 132 are the symmetry setting to make both sides electric field distribute evenly, reduce the colour cast problem. Specifically, the angle of the chamfer may be any angle, for example, the chamfer may be 15 °, 30 °, 45 °, 60 °, or the like. In the technical scheme of the invention, the chamfer angle is 45 degrees, so that the tail end profile is changed towards the rounding trend as much as possible, and the probability that one angle still becomes a sharp angle to influence the liquid crystal molecules 30 to generate disclination is avoided.

As shown in fig. 1, based on the scheme that the pixel unit 130 includes a trunk 131 and branches 132, the technical solution of the present invention provides a first embodiment: the stem 131 further includes a horizontal stem 1311 extending in the horizontal direction and a vertical stem 1312 extending in the vertical direction, the horizontal stem 1311 and the vertical stem 1312 perpendicularly intersect and divide the pixel unit 130 into at least four display regions, and the branches 132 of each adjacent two display regions are symmetrically disposed.

It is understood that the structure of the horizontal stem 1311 and the structure of the vertical stem 1312 may each include a body portion 131a and a first end 131b connected to the body portion 131 a. The pixel unit 130 is divided into at least four display regions by the vertical intersection arrangement of the horizontal stem 1311 and the vertical stem 1312, for example, four display regions, eight display regions, 16 display regions, or more display regions may be divided. Wherein the branches 132 of each display area may have different layouts, thereby achieving the effect of enlarging the viewing angle. Specifically, the intersection of one horizontal stem 1311 and one vertical stem 1312 is perpendicular so that pixel unit 130 has four display areas, and the intersection points may be the midpoints of both horizontal stem 1311 and vertical stem 1312, that is, horizontal stem 131 and vertical stem 131 are vertically bisected by each other, so that the four display areas have the same display area. It can be understood that the material of the main portion 131 and the branch 132 is transparent conductive material, so that when the main portion 131 and the branch 132 are both powered on to generate an electric field, the liquid crystal corresponding to the main portion 131 and the branch 132 may be influenced by the electric field to rotate, when the branches 132 of every two adjacent display regions are symmetrically arranged, the rotation direction of the liquid crystal molecules 30 corresponding to the pixel unit 130 is regular, and the arrangement is such that when a user looks obliquely, the chromaticities of the two adjacent display regions compensate each other, thereby reducing the color cast at the oblique viewing angle.

Further, referring to fig. 1, in order to have a larger opening area and increase the opening ratio, the branches 132 are disposed in a plurality, and the branches 132 are disposed in parallel.

Because the corresponding liquid crystal molecules 30 can transmit light after the branches 132 are electrified, the area proportion occupied by the branches 132 can be improved by arranging a plurality of branches 132 which are arranged in parallel in a display area with a certain area, and further the aperture opening ratio can be improved, and the screen brightness is increased. It is understood that the denser the arrangement of the plurality of branches 132, the brighter the screen can be. Furthermore, the branches 132 in each display area are arranged in parallel, so that the liquid crystal molecules 30 in the same display area are turned the same, and the disclination phenomenon of the liquid crystal molecules 30 is avoided.

Further, in the same display area, the intervals between two adjacent branches 132 are the same. So set up, can make the light that the screen that every two branches 132 correspond sent can compensate the shadow of interval department jointly to can avoid the phenomenon that the interval is too big and appears the black line between some branches 132, reduce the probability that the colour difference appears simultaneously.

In order to further improve the display quality, the angle between the branch 132 and the scan line 120 and the angle between the branch 132 and the data line 110 are both 45 °.

By setting the included angle between the branch 132 and the scan line 120 and the included angle between the branch 132 and the data line 110 to 45 °, the rotation directions of the liquid crystal molecules 30 corresponding to the branch 132 are uniformly distributed, so that the color shift problem at an oblique viewing angle can be effectively reduced.

Based on the above scheme that the pixel unit 130 includes the stem 131 and the branch 132, the present invention further provides a second embodiment: the extension line of the main portion 131, the data line 110 and the scan line 120 together enclose a right triangle, and the branch 132 is perpendicular to the main portion 131.

Through the extension line with trunk 131, data line 110 and scanning line 120 enclose jointly and close and form right triangle, then the extending direction and the data line 110 of trunk 131 are the contained angle setting, the extending direction and the scanning line 120 of trunk 131 also are the contained angle setting, so set up just to make the circular telegram back of trunk 131, the liquid crystal molecule 30 that corresponds trunk 131 department can take place to deflect, light can follow the local of screen correspondence trunk 131 and permeate through, thereby can realize the opening area of increase pixel unit 130, improve the aperture opening ratio, and then improve the effect of luminousness.

Meanwhile, in order to enable the position of the screen corresponding to the branch 132 to be transparent, the branch 132 is disposed perpendicular to the main body 131 in this embodiment, and the liquid crystal at the branch 132 can deflect inevitably, so that light can be transmitted from the position of the screen corresponding to the branch 132, thereby further increasing the opening area of the pixel unit 130, improving the aperture ratio, and further improving the light transmittance.

Based on the above-mentioned solution of the second embodiment, further, in order to enlarge the viewing angle, the pixel unit 130 has two display regions, each display region has a stem 131, and the stems 131 corresponding to the two display regions are disposed perpendicular to each other.

By dividing the pixel unit 130 into two display regions, and vertically arranging the two stems 131 in the two display regions, the extending directions of the two stems 131 are different, and further the directions of the electric fields generated by the two stems 131 are different, and the rotating angles of the corresponding liquid crystal molecules 30 in the two display regions are different, so that the viewing angle of a user is enlarged.

Of course, in other embodiments, the pixel unit 130 may not be limited to having two display regions. The pixel unit 130 may be further divided into four display regions, eight display regions, 16 display regions, or more display regions. And the stems 131 of every two adjacent display areas are arranged perpendicular to each other. It is understood that the branches 132 of each display area are disposed perpendicular to the stem 131, and thus when the stems 131 of each two adjacent display areas are disposed perpendicularly, the branches 132 of each two adjacent display areas are also perpendicular to each other.

In the present invention, as shown in fig. 1, the array substrate 10 further includes a Thin Film Transistor (TFT)140, the thin film transistor 140 includes a source 141, a gate 142, and a drain 143, the source 141 is connected to the data line 110, the gate 142 is connected to the scan line 120, and the drain 143 is connected to the pixel unit 130.

Normally, the tft 140 is usually disposed at a corner of the pixel unit 130, the gate 142 of the tft 140 is connected to the scan line 120, and the scan line 120 is also called a gate line because the scan line 120 plays a role of gating the tft 140; the source 141 of the tft 140 is connected to the data line 110; the drain 143 of the tft 140 is connected to the trunk 131 or the branch 132 of the pixel unit 130 (i.e., the drain 143 of the tft 140 is connected to the pixel electrode). The thin film transistor 140 functions as a switching device, and the thin film transistor 140 is controlled to be turned on or off by a voltage applied to the gate 142 of the thin film transistor 140. When the tft 140 is turned on, the trunk 131 and the branch 132, which are correspondingly connected to the tft 140, are turned on, so that the corresponding pixel unit 130 is in a bright state; when the tft 140 is turned off, the corresponding trunk 131 and branch 132 of the tft 140 are not energized, so that the corresponding pixel unit 130 is in a dark state.

The present invention further provides a display panel, as shown in fig. 8, the display panel includes a color film substrate 20, a liquid crystal, and an array substrate 10, and the specific structure of the array substrate 10 refers to the above embodiments, and since the display panel adopts all technical solutions of all the above embodiments, the display panel at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated here. The color film substrate 20 is parallel to the array substrate 10, the color film substrate 20 is disposed on one side of the array substrate 10 having the pixel unit 130, and the liquid crystal is sandwiched between the color film substrate 20 and the array substrate 10.

The liquid crystal molecules 30 are deflected by applying a voltage across them, and the magnitude of the liquid crystal deflection angle is controlled by the magnitude of the voltage. Therefore, a layer of transparent electrode is further disposed on one side of the color film substrate 20 facing the array substrate 10, the transparent electrode is a common electrode, and when a certain voltage difference exists between the pixel electrode and the common electrode, the liquid crystal molecules 30 between the pixel electrode and the common electrode deflect under the control of the voltage difference, so that a part of light is controlled to pass through the liquid crystal molecules 30 and be projected to the color film substrate 20; by controlling the deflection angle of the liquid crystal molecules 30, the brightness of light penetrating through the color filter substrate 20 can be controlled to generate different gray scales, so that a user can see a corresponding image on the side of the color filter substrate 20 away from the array substrate 10.

Specifically, based on the above scheme of providing the thin film transistor 140 on the array substrate 10, it can be understood that each pixel unit 130 is provided with a thin film transistor 140, so that each thin film transistor 140 can control the on and off of the pixel electrode in the corresponding pixel unit 130. If the thin film transistor 140 is turned on, the pixel electrode connected to the thin film transistor 140 is powered on, and a voltage difference exists between the pixel electrode and the common electrode (or the pixel electrode and the common electrode can be considered as a capacitor as a whole), so that the liquid crystal molecules 30 corresponding to the pixel unit 130 are deflected under the control of the voltage difference, and light can penetrate through the liquid crystal molecules 30 onto the color filter substrate 20; when the thin film transistor 140 is turned off, the pixel electrode corresponding to the thin film transistor 140 is not powered on, there is no voltage difference between the pixel electrode and the common electrode, and there is no voltage between the two ends of the liquid crystal molecules 30, so that the liquid crystal molecules 30 cannot rotate, and the light cannot penetrate through the liquid crystal molecules 30 onto the color film substrate 20, so that the position of the screen corresponding to the pixel unit 130 is displayed as black.

Further, in order to enable the display panel to display a color image, a color filter is further disposed between the color filter substrate 20 and the transparent electrode, so that light of a corresponding color is selected to pass through the color filter and be displayed on the color filter substrate 20. It can be understood that each pixel unit 130 corresponds to a color filter, so that a corresponding picture is displayed at a position of each pixel unit 130 corresponding to the color filter substrate 20.

In general, in order to stably dispose the liquid crystal molecules 30 between the array substrate 10 and the color filter substrate 20, the display panel further includes a sealant, and the sealant is disposed at a peripheral position between the array substrate 10 and the color filter substrate 20 and enables the array substrate 10 and the color filter substrate 20 to be bonded together, so as to prevent the liquid crystal molecules 30 between the array substrate 10 and the color filter substrate 20 from overflowing, and achieve an effect of blocking the liquid crystal molecules 30 from the outside.

In addition, since not all light can pass through the panel, except for the data lines, the scan lines, the tfts, and other places where the light is not completely transmitted, the light in these places is not controlled by the voltage, and the correct gray scale cannot be displayed, the areas of the color filter substrate 20 corresponding to these places need to be shielded by the black matrix, so as to avoid interfering with the normal brightness of other light-transmitting areas.

The present invention further provides a display, which includes a display panel, and the specific structure of the display panel refers to the above embodiments, and since the display employs all technical solutions of all the above embodiments, the display at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.

Since the liquid crystal molecules 30 in the display panel do not emit light, in order to control light, the display may further include a backlight module 40, as shown in fig. 9, the backlight module 40 is disposed on a side of the array substrate 10 away from the color filter substrate 20. The backlight module 40 is used to provide a light source to project light to the array substrate 10. The backlight module 40 includes a backlight source 410, a reflective plate 420, a diffuser plate 430, and other optical films, wherein the backlight source 410 is disposed on the reflective plate 420 or disposed on two opposite sides of the reflective plate 420, and the reflective plate 420 is used for projecting light toward the display panel; the diffusion plate 430 is disposed on a side of the backlight source 410 close to the display panel, so as to uniformly distribute light to each region to achieve the effect of alleviating hot spots, thereby providing a bright light source for the display panel.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
