Detailed Description

Embodiments of the present application will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the application are shown, and in which it is to be understood that the embodiments described are merely illustrative of some, but not all, of the embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An OLED display panel is currently a mainstream display panel, and an OLED is a display screen made of organic electroluminescent light emitting diodes. The organic electroluminescent diode has the advantages of no need of backlight source, high contrast, thin thickness, wide viewing angle, fast reaction speed, wide application temperature range, simple structure and manufacture process, etc. and is considered as a new application technology of the next generation of flat panel display.

Because the OLED display panel is provided with the semitransparent cathode shared by the whole surface, the OLED display panel has strong reflection to the environment, and because of the periodic arrangement of the sub-pixels, when a monochromatic picture is displayed, the interference problem can occur between the reflected ambient light and self-display luminescence.

As shown in fig. 1 to fig. 3, fig. 1 is a schematic diagram of a display unit layout of a display panel, fig. 2 is a partial enlarged view of a display panel during monochrome display, fig. 3 is an effect diagram of a display panel through two-dimensional fourier analysis during monochrome display, and a white frame in fig. 2 is a same sub-pixel with the same light emission color. The light emitting colors of the sub-pixels 01 in the same row are the same, and in other ways, the light emitting colors of the sub-pixels 01 in the same row may be different.

Due to the periodic arrangement of the sub-pixels, when the display panel displays monochrome, the display panel reflects ambient light, sharp interference fringes are easily generated, and through two-dimensional Fourier analysis, based on FIG. 3, only the interference fringes can be concentrated in a cross-shaped area in the middle of the display screen.

Although reflection of ambient light can be reduced to some extent by providing an antireflection layer on the light exit side of the display panel, reflection with a greater intensity still exists, and the interference effect is still significant. Optionally, the display panel in the embodiment of the present application is a display panel, and the interference problem exists. However, since the LCD display panel needs to display an image based on a backlight, the interference effect is weak and is not enough to affect the display effect. Therefore, the display panel in the embodiment of the present application is preferably an OLED display panel. Although reflection interference problem is less strong among the LCD display panel, the sub-pixel in the LCD display panel also can adopt this application technical scheme overall arrangement, can further make the display interference weaker, promotes the display effect.

In order to solve the above problem, an embodiment of the present application provides a display panel, where in the display panel is provided with sub-pixels having the same emission color, at least two of the sub-pixels have different first axis extending directions, so that the periodic arrangement of the sub-pixels having the same emission color in the display panel is destroyed, interference fringes caused by reflected ambient light can be solved, and image display quality is improved.

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 4, fig. 4 is a schematic diagram of an arrangement of pixel units in a display panel according to an embodiment of the present disclosure, where the display panel includes: an array substrate 11; a plurality of pixel units 12 disposed on one side of the array substrate 11, wherein the pixel units 12 include a plurality of sub-pixels 121 of different light emission colors, and only one sub-pixel 121 of one light emission color is shown in fig. 4; the sub-pixel 121 has opposite first and second ends. In the sub-pixels 121 with the same emission color, at least two of the sub-pixels 121 have different first axial extension directions, and the first axial extension direction of the sub-pixel 121 is a connection line from a first end of the sub-pixel to a second end of the sub-pixel. Alternatively, if the sub-pixel 121 is rectangular, two short sides thereof are respectively a first end and a second end.

In the display panel, the sub-pixels 121 with the same light emission color are arranged, and at least two sub-pixels 121 have different first axial extension directions, so that the periodic arrangement of the sub-pixels 121 with the same light emission color in the display panel is destroyed, interference fringes caused by reflected ambient light can be solved, and the image display quality is improved.

The display units 12 are arranged in an array, the standard direction a is parallel to the column direction, and the pixel units 12 in the last column point to the pixel units 12 in the first column. If the first axis extending direction of the sub-pixel 121 is the same as the standard direction a, the sub-pixel 121 is a standard sub-pixel. If the first axis extending direction of the sub-pixel 121 is different from the standard direction a, the sub-pixel 121 is a rotation-state sub-pixel. The angle between the standard-state sub-pixel and the first axis of the rotation-state sub-pixel is not more than 180 degrees.

Each pixel unit 12 corresponds to one pixel region, and the pixel unit 12 is located in the corresponding pixel region. For the standard sub-pixel, the lower end shown in fig. 4 is the first end of the standard sub-pixel, the upper end shown in fig. 4 is the second end of the standard sub-pixel, and the included angle between the first axis extending direction of the standard sub-pixel and the standard direction a is 0. For the rotating sub-pixel, the geometric center of the pixel area where the rotating sub-pixel is located is used as a rotating shaft, and the rotating sub-pixel is rotated by a preset angle to a set position along a preset rotating direction, so that the first axial extending direction of the rotating sub-pixel is different from the standard direction A. Wherein the rotation angle is less than 360 deg.. All the rotation states are based on the same rotation direction, namely clockwise direction or anticlockwise direction.

Setting the display panel to have a plurality of sub-pixel sets, where the sub-pixel sets include a plurality of sub-pixels 121, the light emitting colors of the sub-pixels 121 in the same sub-pixel set are the same, and the light emitting colors of the sub-pixels 121 in different sub-pixel sets are different. In the embodiment of the present application, at least one sub-pixel set is configured to have sub-pixels in a rotated state. If a set of sub-pixels has a rotating sub-pixel, the set of sub-pixels can be set to have one or more of the rotating sub-pixels based on the requirement.

In a traditional display panel, the first axis extending directions of all sub-pixels are standard directions a, and the sub-pixels in any sub-pixel set are strictly and periodically arranged, so that for any sub-pixel set, when monochrome display is performed, emergent light and light with the same color in reflected ambient light form interference, and interference fringes are generated to influence the display quality.

In this application, for prior art, through the first axis of rotation part sub-pixel for its first axis extending direction is different with standard direction A, thereby can destroy the periodic arrangement that corresponds color sub-pixel. In the same display unit 12, the light emission colors of the sub-pixels 121 are different from each other. For a pixel unit 12, if there is a rotating sub-pixel, there may be one rotating sub-pixel or a plurality of rotating sub-pixels.

As can be seen from the above description, if the sub-pixel set has the rotated-state pixel, the periodic arrangement of the sub-pixels 121 in the sub-pixel set is destroyed, and interference fringes caused by reflection of ambient light of the same color when the sub-pixels 121 in the sub-pixel set perform monochrome color development can be solved. Therefore, the set of multiple sub-pixels is provided with the sub-pixels in the rotating state, and when the sub-pixels in all colors are displayed in a single color, the problem of reflection interference can be solved.

As shown in fig. 5, fig. 5 is a schematic layout diagram of two adjacent sub-pixels used in the embodiment of the present application, and in two adjacent pixel units 12, if the first axis extending directions of the sub-pixels 121 with the same emission color are different, an included angle a between the first axis extending directions is not more than 30 °, so that when the periodic layout of the sub-pixels 121 is destroyed, the included angle between the first axis extending directions of two adjacent sub-pixels 121 with the same emission color is prevented from being too large, which may cause a visual difference that human eyes can distinguish, thereby affecting a local display effect.

Fig. 5 illustrates, by taking the sub-pixels 121 with the same color in two adjacent pixel units 12 in the same row as an example, the first axial extending direction of two adjacent sub-pixels 121 has an included angle a smaller than 30 °. In other manners, in two adjacent pixel units 12 in the same column, the sub-pixels 121 with the same color have an included angle a not exceeding 30 °.

In the embodiment shown in fig. 4, there is at least one first pixel group 13, and the first direction X is parallel to the row direction and is directed from the first row of pixel units to the last row of pixel units, and the first direction X may also be the reverse of the illustrated direction. Fig. 4 shows that a row of pixel units includes one first pixel group 13, and obviously, the first direction X may be set according to requirements, and the same row of pixel units has a plurality of first pixel groups 13 arranged in sequence in the first direction X.

The first pixel group 13 includes P pixel units 12 sequentially arranged in the first direction X, where P is a positive integer greater than 1; the pixel unit 12 has a first sub-pixel for emitting a first color light; the first pixel group has P first sub-pixels. The setting pixel unit 12 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, where the first sub-pixel may be any one of the three sub-pixels, for example, the first sub-pixel may be set as the green sub-pixel R, and in other ways, the first sub-pixel may also be set as one of the other two color sub-pixels, which is not limited in this embodiment.

In the same first pixel group 13, in the first direction X, the first axial extension directions of the ith and jth first sub-pixels are the same, i and j are positive integers not greater than P, and i + j is P + 1.

As shown in fig. 4, in the first direction X, the first pixel group 13 includes 10 pixel units 12, and therefore has 10 first sub-pixels, in the first direction X, the first axial extending direction of the 1 st first sub-pixel is the same as that of the 10 th first sub-pixel, the first axial extending direction of the 2 nd first sub-pixel is the same as that of the 9 th first sub-pixel, and …, and the first axial extending direction of the 5 th first sub-pixel is the same as that of the 6 th first sub-pixel. If P is an odd number, in the same first pixel group 13, the (P +1)/2 th first sub-pixel has a single first axis extending direction in the first pixel group 13, and the first axis extending directions of the other first sub-pixels are the same two by two.

The number P of the first sub-pixels in the first pixel group 13 in the present application is not limited to 10 shown in fig. 4, and may be set to any number based on the requirement. In the first pixel group 13, P is generally set to be not less than 12, and an included angle between the first axis extending directions of two adjacent first sub-pixels is not more than 30 °, so that when the problem of reflection interference is reduced or even eliminated, a display difference recognizable by human eyes due to an excessively large included angle between the first axis extending directions of two adjacent first sub-pixels is avoided.

As shown in fig. 4, at least one second pixel group 14 is provided, the second direction Y is parallel to the column direction and is directed from the first column of pixel units to the last column of pixel units, and the second direction Y may be the reverse of the illustrated direction. Fig. 4 shows that a column of pixel units includes one second pixel group 14, and obviously, the second direction Y can be set according to requirements, and the same column of pixel units has a plurality of second pixel groups 14 arranged in sequence in the second direction Y.

The second pixel group 14 includes Q pixel units 12 arranged in sequence in the second direction Y, where Q is a positive integer greater than 1; q first sub-pixels are arranged in the second pixel group; the second direction Y intersects the first direction X; in the embodiment shown in fig. 4, the first direction X is perpendicular to the second direction Y.

In the same second pixel group 14, in the second direction Y, the first axial extension directions of the mth first sub-pixel and the nth first sub-pixel are the same, m and n are positive integers not greater than Q, and m + n is Q + 1.

In fig. 4, in the second direction Y, the second pixel group 14 includes 10 pixel units 12, and therefore has 10 first sub-pixels, in the second direction Y, the first axial extending direction of the 1 st first sub-pixel is the same as that of the 10 th first sub-pixel, the first axial extending direction of the 2 nd first sub-pixel is the same as that of the 9 th first sub-pixel, …, and the first axial extending direction of the 5 th first sub-pixel is the same as that of the 6 th first sub-pixel. If Q is odd, in the same second pixel group 14, (Q +1)/2 first sub-pixels have a single first axial extension direction in the second pixel group 14, and the first axial extension directions of other first sub-pixels are the same two by two. The number Q of the first sub-pixels in the second pixel group 14 in the present application is not limited to 10 shown in fig. 4, and any number of Q may be set based on the requirement. In the second pixel group 14, Q is generally set to be not less than 12, and an included angle between the first axis extending directions of two adjacent first sub-pixels is not more than 30 °, so that when the problem of reflection interference is reduced or even eliminated, a display difference recognizable by human eyes due to an excessively large included angle between the first axis extending directions of two adjacent first sub-pixels is avoided.

In the manner shown in fig. 4, in the same first pixel group 13, in the first direction X, the included angle between the first axis extending direction of the first sub-pixel and the standard direction a increases first and then decreases, as shown in fig. 4, in a first pixel group 13, the included angle between the first axis extending direction of the 1 st first sub-pixel to the 5 th first sub-pixel and the standard direction a gradually increases, and the included angle between the first axis extending direction of the 6 th first sub-pixel to the 10 th first sub-pixel and the standard direction a gradually decreases. In the same first pixel group 13, the included angle between the first axis extending directions of two adjacent first sub-pixels is not more than 30 °, so that the problem of reflection interference is reduced or even eliminated, and at the same time, the display difference recognizable by human eyes is avoided due to the overlarge included angle between the first axis extending directions of two adjacent first sub-pixels.

In the same first pixel group 13, the included angles in the first axis extending directions of any two adjacent first sub-pixels are the same. For any adjacent three first sub-pixels in the first pixel group 13, the first axis extending direction of the (p-1) th first sub-pixel and the first axis extending direction of the (p) th first sub-pixel have a first included angle, the first axis extending direction of the (p) th first sub-pixel and the first axis extending direction of the (p +1) th first sub-pixel have a second included angle, and the first included angle is equal to the second included angle. In this way, the layout of the first sub-pixels in the first direction X is facilitated. P is a positive integer greater than 1, and P +1 is not greater than P.

In the manner shown in fig. 4, in the same second pixel group 14, in the second direction Y, the included angle between the first axis extending direction of the first sub-pixel and the standard direction a increases first and then decreases, as shown in fig. 4, in a second pixel group 14, the included angle between the first axis extending direction of the 1 st first sub-pixel to the 5 th first sub-pixel and the standard direction a gradually increases, and the included angle between the first axis extending direction of the 6 th first sub-pixel to the 10 th first sub-pixel and the standard direction a gradually decreases. In the same first pixel group 13, the included angle between the first axis extending directions of two adjacent first sub-pixels is not more than 30 °, so that the problem of reflection interference is reduced or even eliminated, and at the same time, the display difference recognizable by human eyes is avoided due to the overlarge included angle between the first axis extending directions of two adjacent first sub-pixels.

In the same second pixel group 14, the included angles in the first axis extending directions of any two adjacent first sub-pixels are the same. For any adjacent three first sub-pixels in the second pixel group 14, the first axis extending direction of the q-1 th first sub-pixel and the first axis extending direction of the q-th first sub-pixel have a third angle, the first axis extending direction of the q-th first sub-pixel and the first axis extending direction of the q +1 th first sub-pixel have a fourth angle, and the third angle is equal to the fourth angle. In this way, the layout of the first sub-pixels in the second direction Y is facilitated. Q is a positive integer greater than 1, and Q +1 is not greater than Q.

In the sub-pixels 121 with the same light emission color, the first axis extending directions of any two adjacent sub-pixels 121 may be set to be different. In another embodiment, in the sub-pixels 121 having the same light emission color, the first axis extension directions of at least two adjacent sub-pixels 121 are different, and the first axis extensions of two adjacent sub-pixels 121 are the same. In the embodiment of the present application, two adjacent sub-pixels 121 are two adjacent sub-pixels 121 in a row direction or a column direction, or two adjacent sub-pixels 121 in other directions, where the other directions may be diagonal directions of the display area.

In the display panel shown in fig. 4, due to the existence of the sub-pixels in the rotating state, the periodic arrangement of the sub-pixels in the same color in the conventional display panel shown in fig. 1 and 2 is destroyed, so that the interference problem of reflected light is reduced, the halo is blurred, and the display quality is improved.

As shown in fig. 6, fig. 6 is a schematic view of an arrangement of pixel units in another display panel provided in this embodiment of the present application, based on the foregoing embodiment, in the display panel shown in fig. 6, at least two of the pixel units 12 have different second axis extending directions, the pixel unit 12 has a third end and a fourth end that are opposite to each other, and the second axis extending direction of the pixel unit 12 is a connection line direction from the third end to the fourth end of the pixel unit 12. In the pixel unit 12, the first end of each sub-pixel 121 is close to the third end of the pixel unit 12, and the second end of each sub-pixel 121 is close to the fourth end of the pixel unit 12.

In the same display unit 12, the light emission colors of the sub-pixels 121 are different from each other. For a pixel unit 12, if there is a rotating sub-pixel, there may be one rotating sub-pixel or a plurality of rotating sub-pixels.

If all the sub-pixels 121 in the pixel unit 12 are standard sub-pixels, the extending direction of the second axis of the pixel unit 12 is the same as the standard direction a, and the pixel unit 12 is a standard pixel unit. For the standard pixel unit, the lower end shown in fig. 6 is the third end of the standard pixel unit, the upper end shown in fig. 6 is the fourth end of the standard pixel unit, and the included angle between the second axis extending direction of the standard pixel unit and the standard direction a is 0. If a pixel cell 12 has a rotated sub-pixel, then the pixel cell is a non-standard pixel cell.

As shown in fig. 6, in the same pixel unit, the first axis extending directions of all the sub-pixels 121 are the same, that is, all the sub-pixels 121 are rotation sub-pixels and have the same first axis extending directions, so that the pixel unit 12 is manufactured by using the same mask. For the non-standard pixel unit, if the first axis extending directions of the sub-pixels are the same, the pixel unit is a rotation-state pixel unit. For the rotating pixel unit, it is equivalent to a standard pixel unit in the pixel area to which the rotating pixel unit belongs, and the geometric center of the pixel area is used as a rotating shaft, and the rotating pixel unit is rotated by a preset angle to a set position along a preset rotation direction, so that the extension direction of the second axis is different from the standard direction a, wherein the rotation angle is less than 360 degrees, and in the rotation process, all the sub-pixels 121 in the pixel unit rotate synchronously.

Moreover, if the pixel unit 12 has the sub-pixels in the rotation state, since the first axial extension directions of the sub-pixels 121 in the same pixel unit 12 are all the same, all the sub-pixels 121 in the pixel unit 12 are the sub-pixels in the rotation state, and the sub-pixels in each color in the same pixel unit 12 can be rotated in a manner similar to the conventional layout manner, so that the interference problem caused by reflection when the sub-pixels in each color are displayed in a single color can be reduced or even eliminated.

In other ways, if a pixel unit 12 has a plurality of rotation-state sub-pixels, the first axis extending direction of each rotation-state sub-pixel may be set to be different, or if a pixel unit 12 has a rotation-state sub-pixel, one rotation-state sub-pixel may be set, and the other sub-pixels 121 are standard-state sub-pixels.

As shown in fig. 6, the first direction X may be set, and the second axial extension directions of any two adjacent pixel units 12 are different; in the second direction Y, the second axial extension directions of any two adjacent pixel units 12 are different; as mentioned above, the first direction X intersects the second direction Y to better reduce or even eliminate the problem of reflection interference, thereby improving the display quality.

In the embodiment shown in fig. 6, there is at least one first pixel group 13, and the first direction X is parallel to the row direction and is directed from the first row of pixel units to the last row of pixel units, and the first direction X may also be the reverse of the illustrated direction. Fig. 6 shows that a row of pixel units includes one first pixel group 13, and obviously, the pixel units in the same row in the first direction X may be arranged according to requirements, and have a plurality of first pixel groups 13 arranged in sequence in the first direction X.

The first pixel group 13 includes P pixel units 12 sequentially arranged in the first direction X, where P is a positive integer greater than 1; the pixel unit 12 has a first sub-pixel for emitting a first color light; the first pixel group has P first sub-pixels. The setting pixel unit 12 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, where the first sub-pixel may be any one of the three sub-pixels, for example, the first sub-pixel may be set as the red sub-pixel R, and in other ways, the first sub-pixel may also be set as one of the other two color sub-pixels, which is not limited in this embodiment.

As shown in fig. 6, in the first direction X, the first pixel group 13 includes 10 pixel units 12, and therefore has 10 first sub-pixels, in the first direction X, the first axial extending direction of the 1 st first sub-pixel is the same as that of the 10 th first sub-pixel, the first axial extending direction of the 2 nd first sub-pixel is the same as that of the 9 th first sub-pixel, and …, and the first axial extending direction of the 5 th first sub-pixel is the same as that of the 6 th first sub-pixel. If P is an odd number, in the same first pixel group 13, the (P +1)/2 th first sub-pixel has a single first axis extending direction in the first pixel group 13, and the first axis extending directions of the other first sub-pixels are the same two by two.

The number P of the first sub-pixels in the first pixel group 13 in the present application is not limited to 10 shown in fig. 6, and may be set to any number based on the requirement. In the first pixel group 13, P is generally set to be not less than 12, and an included angle between the first axis extending directions of two adjacent first sub-pixels is not more than 30 °, so that when the problem of reflection interference is reduced or even eliminated, a display difference recognizable by human eyes due to an excessively large included angle between the first axis extending directions of two adjacent first sub-pixels is avoided.

If a row of pixel units has a plurality of first pixel groups 13, for the same row of pixel units, the first axis extending direction of the xth first sub-pixel in each first pixel group 13 is set to be the same, so as to use the same mask to manufacture the pixel units in the first pixel group 13, where x is a positive integer not greater than P. In the first direction X, it is obvious that the first axis extending direction of the xth first sub-pixel in each first pixel group 13 may be different.

As shown in fig. 6, at least one second pixel group 14 is provided, the second direction Y is parallel to the column direction and is directed from the first column of pixel units to the last column of pixel units, and the second direction Y may be the reverse of the illustrated direction. Fig. 6 shows that a column of pixel units includes one second pixel group 14, and obviously, the second direction Y can be set according to requirements, and the same column of pixel units has a plurality of second pixel groups 14 arranged in sequence in the second direction Y.

The second pixel group 14 includes Q pixel units 12 arranged in sequence in the second direction Y, where Q is a positive integer greater than 1; q first sub-pixels are arranged in the second pixel group; the second direction Y intersects the first direction X; in the embodiment shown in fig. 6, the first direction X is perpendicular to the second direction Y.

In fig. 6, in the second direction Y, the second pixel group 14 includes 10 pixel units 12, and therefore has 10 first sub-pixels, in the second direction Y, the first axial extending direction of the 1 st first sub-pixel is the same as that of the 10 th first sub-pixel, the first axial extending direction of the 2 nd first sub-pixel is the same as that of the 9 th first sub-pixel, …, and the first axial extending direction of the 5 th first sub-pixel is the same as that of the 6 th first sub-pixel.
