[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. 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 invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As shown in fig. 4 and fig. 5, fig. 4 is a top view of a display panel according to an embodiment of the present invention, and fig. 5 is a schematic partial enlarged view of a region a in fig. 4, in which an embodiment of the present invention provides a display panel, including: the display area 1, the display area 1 includes the adjacent ordinary display area 11 and abnormal shape display area 12 arranged, the abnormal shape display area 12 includes the first edge 4; the display area 1 includes a plurality of scan lines (not shown in the figure) arranged along the first direction Y and extending along the second direction X, and an included angle a between at least one tangent line of the first edge 4 and the second direction X is an acute angle, that is, the first edge 4 is a shaped edge, for example, the first edge 4 is a curve or a slant line; the shaped display area 12 comprises a plurality of shaped edge sub-pixels 51 adjacent to the first edge 4, each shaped edge sub-pixel 51 being shaped as a non-rectangular parallelogram; the normal display region 11 includes a plurality of normal sub-pixels 52, and each of the normal sub-pixels 52 has a rectangular shape.
Specifically, the scan lines extend in the second direction X, that is, the pixels are arranged in a plurality of columns in the second direction X and in a plurality of rows in the first direction Y, the scan lines drive the pixels in units of rows so that each pixel has corresponding display brightness, and in the normal display region 11, the extending direction of the display edges is consistent with the first direction Y or the second direction X, so that the shape of the normal sub-pixels 52 is rectangular, i.e., the shape of the edges of the normal display region 11 can be matched. And an angle b between at least one tangent of the first edge 4 and the second direction X is an acute angle, so that, in order to match the first edge 4, the shape of the special-shaped edge sub-pixel 51 is set to be a non-right-angle parallelogram, so that the inclination degree of the corresponding special-shaped edge sub-pixel 51 can be set according to the inclination degree of each position of the first edge 4, it should be noted that the inclination degree of the first edge 4 refers to an angle between the first edge 4 and the first direction Y, and the inclination degree of the special-shaped edge sub-pixel 51 refers to an angle between a long side of the special-shaped edge sub-pixel 51 and the first direction Y.
In the display panel in the embodiment of the invention, the special-shaped edge sub-pixel corresponding to the first edge in the special-shaped display area is set to be the non-right-angle parallelogram, so that the inclination degree of the corresponding special-shaped edge sub-pixel can be set according to the inclination degree of the first edge, and the inclination degree of the edge is close to that of the special-shaped edge sub-pixel; on the other hand, the aperture ratio of the sub-pixels at the special-shaped edges does not need to be changed, so that the color cast of the display picture at the special-shaped edges is improved while the saw tooth feeling of the display picture at the special-shaped edges is reduced.
Alternatively, as shown in fig. 5, the long side of each of the shaped-edge sub-pixels 51 is disposed along the extending direction of the edge of the display area adjacent thereto.
Alternatively, the long side of each special-shaped edge sub-pixel 51 is arranged along the extending direction of the display area edge adjacent to the long side, that is, two ends of one long side of each special-shaped edge sub-pixel 51 are respectively in contact with the first edge 4, and the extending direction of the first edge 4 from the extending direction of the straight line where the two ends in contact with the special-shaped edge sub-pixel 51 are located is understood as the extending direction of the display area edge adjacent to the special-shaped edge sub-pixel 51. This structure is suitable for various shapes of the first edge 4, for example, for the curved first edge 4, it is equivalent to divide the first edge 4 for each row of pixels, each divided part of the first edge 4 corresponds to one special-shaped edge sub-pixel 51, and the extending direction of the first edge 4 of each special-shaped edge sub-pixel 51 and the corresponding part thereof is provided with the extending direction of the long side of the special-shaped edge sub-pixel 51, so that the inclination degree of each special-shaped edge sub-pixel 51 is matched with the inclination degree of the corresponding part of the first edge 4.
Optionally, as shown in fig. 5, the special-shaped display area 12 further includes a plurality of normal sub-pixels 52, each of the normal sub-pixels 52 in the special-shaped display area 12 is rectangular, and in the special-shaped display area 12 and the normal display area 11, the long sides of any normal sub-pixel 52 are arranged along the first direction Y, that is, the long sides of the normal sub-pixels 52 extend along the first direction Y; in the shaped display area 12, the shaped edge sub-pixel 51 is located on at least one side of the normal sub-pixel 52 in the second direction X.
Specifically, the special-shaped display area may only include the sub-pixels of the non-rectangular parallelogram, or as shown in fig. 1, the special-shaped display area 12 may include, in addition to the special-shaped edge sub-pixels 51 of the non-rectangular parallelogram, the normal sub-pixels 52 having the same shape as the sub-pixels in the normal display area 11, and the shape of the normal sub-pixels 52 is rectangular.
Alternatively, as shown in fig. 5, in the special-shaped display area 12, a plurality of transition sub-pixels 53 are arranged between the special-shaped edge sub-pixel 51 and the ordinary sub-pixel 52, and each transition sub-pixel 53 is in the shape of a non-right-angle parallelogram; as shown in fig. 6, fig. 6 is a schematic diagram of a row of pixels in the special-shaped display area in fig. 5, and the special-shaped edge sub-pixel 51 is transited to the normal sub-pixel 52 through the transition sub-pixel 53 along the second direction X, and an included angle c between the transition sub-pixel 53 and the first direction Y gradually decreases.
Specifically, the angle between the transition sub-pixel 53 and the first direction Y is the angle between the extending direction of the long side of the transition sub-pixel 53 and the first direction Y, that is, in the same row of pixels, the angle between the extending direction of the long side of each sub-pixel and the first direction Y gradually decreases in the direction from the special-shaped edge sub-pixel 51 to the common sub-pixel 52 until the extending direction of the long side of the sub-pixel becomes the first direction Y. Thus, on the one hand, the inclination degree of the special-shaped edge sub-pixel 51 is set according to the inclination degree of the first edge 4, so that the color cast of the display picture at the special-shaped edge is improved while the saw-tooth feeling of the display picture at the special-shaped edge is reduced; on the other hand, the normal sub-pixels 52 are arranged at positions far away from the first edge 4, so that the pixel structure in the special-shaped display area 12 is closer to the pixel structure in the ordinary display area 11, and poor display caused by inconsistency between the display picture in the special-shaped display area 12 and the display picture in the ordinary display area 11 is improved; on the other hand, in the same row of pixels, in the direction from the special-shaped edge sub-pixel 51 to the ordinary sub-pixel 52, the included angle c between the transition sub-pixel 53 and the first direction Y gradually decreases, so that a gradually changing transition structure is formed between the special-shaped edge sub-pixel 51 and the ordinary sub-pixel 52, and the display defect caused by the abrupt change between the special-shaped edge sub-pixel 51 and the ordinary sub-pixel 52 is improved.
Alternatively, as shown in FIG. 6, in the second direction X, the included angle between the extending directions of the long sides of any two adjacent transition sub-pixels 53 is a, 1 ≦ a ≦ 5.
Specifically, in order to further make the gradual change effect between the special-shaped edge sub-pixel 51 and the ordinary sub-pixel 52 more gradual and the gradual change amplitude is closer, an included angle between the extending directions of the long edges of any two adjacent transition sub-pixels 53 is set to be a, and a is greater than or equal to 1 degree and less than or equal to 5 degrees.
Alternatively, as shown in fig. 5, the first edge 4 may form an angle of more than 60 ° with the second direction X.
Specifically, an angle between the first edge 4 and the second direction X of more than 60 ° means that an angle between a tangential direction of any position of the first edge 4 and the second direction X of more than 60 °, and in this structure, it is described that the extending direction of the first edge 4 is relatively close to the first direction Y, and in this structure, the transition sub-pixel 53 is deflected to a small extent, that is, the extending direction of the long side of the sub-pixel gradually transitions from the irregular edge sub-pixel 51 to the normal sub-pixel 52. If the included angle between the tangential direction of the first edge 4 and the first direction Y is larger, the transition sub-pixel 53 needs to deflect with a larger amplitude to enable the extending direction of the long side of the sub-pixel to gradually transition from the special-shaped edge sub-pixel 51 to the normal sub-pixel 52, and the transition sub-pixel 53 undergoes a larger deflection to cause a larger difference between the adjacent sub-pixels, thereby causing a poor display due to an excessively large deflection angle between the adjacent transition sub-pixels 53. Therefore, the structure shown in fig. 5 using the transition sub-pixel 53 is suitable for the case where the angle between the first edge 4 and the second direction X is greater than 60 °, and if the angle between the first edge 4 and the second direction X is less than or equal to 60 °, the corresponding sub-pixel may be disposed in other manners.
Alternatively, as shown in fig. 7, fig. 7 is another partially enlarged schematic view of the region a in fig. 4, in the special-shaped display region 12, in each row of sub-pixels, a plurality of fixed slope sub-pixels 54 are arranged between the special-shaped edge sub-pixel 51 and the normal sub-pixel 52, each fixed slope sub-pixel 54 is in the shape of a non-right-angle parallelogram, in each row of sub-pixels, the long sides of any fixed slope sub-pixel 54 have the same extending direction, and the included angle between the extending direction of the long side of the fixed slope sub-pixel 54 and the extending direction of the long side of the special-shaped edge sub-pixel 51 is smaller than a preset angle; in the special-shaped display area 12, in each row of sub-pixels, an irregular sub-pixel 55 is arranged between the fixed-slope sub-pixel 54 and the normal sub-pixel 52, the irregular sub-pixel 55 is adjacent to the normal sub-pixel 52, and the irregular sub-pixel 55 comprises a first side and a second side, wherein the first side extends in the same direction as the long side of the fixed-slope sub-pixel 54, and the second side extends in the same direction as the long side of the normal sub-pixel 52.
Specifically, the sub-pixel 53 may be disposed between the special-shaped edge sub-pixel 51 and the normal sub-pixel 52 in addition to the transition sub-pixel 53 as shown in fig. 5, for example, as shown in fig. 7, the fixed slope sub-pixel 54 is disposed between the special-shaped edge sub-pixel 51 and the normal sub-pixel 52, and in the same row of sub-pixels, an included angle between an extending direction of a long side of the fixed slope sub-pixel 54 and an extending direction of a long side of the special-shaped edge sub-pixel 51 is smaller than a preset angle, wherein the preset angle refers to an angle at which the extending direction of the long side of the fixed slope sub-pixel 54 and the extending direction of the long side of the special-shaped edge sub-pixel 51 are close to each other, so that the fixed slope sub-pixel 54 and the special-shaped edge sub-pixel 51 have similar structures and extending directions, and the preset. Since the extending direction of the long side of the fixed slope sub-pixel 54 is different from the extending direction of the long side of the normal sub-pixel 52, in order to improve the display effect between the fixed slope sub-pixel 54 and the normal sub-pixel 52, the irregular sub-pixel 55 is disposed between the fixed slope sub-pixel 54 and the normal sub-pixel 52, the first side of the irregular sub-pixel 55 is an edge far from the normal sub-pixel 52, since the edge is close to the fixed slope sub-pixel 54, the extending direction of the first side is the same as the extending direction of the long side of the fixed slope sub-pixel 54, the second side of the irregular sub-pixel 55 is an edge in contact with the normal sub-pixel 52, and in order to match the normal sub-pixel 52, the extending direction of the second side is the same as the extending direction of the long side of the normal sub-pixel 52. By disposing the irregular sub-pixel 55 between the fixed-slope sub-pixel 54 and the normal sub-pixel 52, a display effect capable of matching the fixed-slope sub-pixel 54 and the normal sub-pixel 52 at the same time is obtained between the fixed-slope sub-pixel 54 and the normal sub-pixel 52.
Alternatively, as shown in fig. 8, fig. 8 is a top view of a partial area of another display panel in an embodiment of the present invention, the extending directions of the long sides of any of the irregular-edge sub-pixels 51 are the same, and the angle between the extending direction of the long side of any of the irregular-edge sub-pixels 51 and the first edge 4 is smaller than a preset angle.
Specifically, in the structure shown in fig. 5, the long side of each of the special-shaped edge sub-pixels 51 is disposed along the extending direction of the edge of the display area adjacent thereto, whereas in the structure shown in fig. 8, the extending direction of the long side of any of the special-shaped edge sub-pixels 51 is the same, the structure shown in fig. 8 is more suitable for the case where the first edge 4 is a straight line or the first edge 4 is a curved line, but the degree of curvature of the curved line is small, and the angle between the extending direction of the long side of the special-shaped edge sub-pixel 51 and the first edge 4 is smaller than a preset angle, where the preset angle refers to an angle at which the extending direction of the long side of the special-shaped edge sub-pixel 51 is close to the extending direction of the first edge 4, which is preferably 0, and in the structure shown in fig. 8, since the degree of inclination of the special-shaped edge sub-pixel 51 matches the degree of inclination, the sawtooth sense of the display frame at the special-shaped edge is reduced, and in addition, the aperture opening ratio of the sub-pixels at the special-shaped edge is not required to be changed, so that the sawtooth sense of the display frame at the special-shaped edge is reduced, and the color cast of the display frame at the special-shaped edge is improved.
It should be noted that the special-shaped display areas 12 in fig. 5, 6 and 7 each include two first edges 4 oppositely disposed in the second direction X, and the common sub-pixel 52 is disposed between the two first edges 4. As shown in fig. 5 and 6, a transition sub-pixel 53 is arranged between the first edge 4 on the left side and the normal sub-pixel 52, and a transition sub-pixel 53 is also arranged between the first edge 4 on the right side and the normal sub-pixel 52; as shown in fig. 7, a fixed slope sub-pixel 54 and an irregular sub-pixel 55 are disposed between the first edge 4 on the left side and the normal sub-pixel 52, and a fixed slope sub-pixel 53 and an irregular sub-pixel 55 are also disposed between the first edge 4 on the right side and the normal sub-pixel 52. However, fig. 5, 6 and 7 only illustrate the structure of one of the special-shaped display areas 12 in the embodiment of the present invention, the embodiment of the present invention is not limited to the specific structure of the special-shaped display area 12, and the special-shaped display area 12 does not necessarily have two first edges opposite to each other in the second direction X. In addition, fig. 5, fig. 6 and fig. 7 only illustrate a part of the display area in fig. 4, for example, the display area above the special-shaped display area 12 is not illustrated and not described, and the structure in this part of the display area is not limited in the embodiment of the present invention, and may be set as in the prior art or as in the embodiment of the present invention.
Optionally, as shown in fig. 8, the shaped display area 12 further comprises a second edge 6 opposite the first edge 4 in the second direction X; a plurality of fixed slope sub-pixels 54 are arranged between the special-shaped edge sub-pixel 51 and the second edge 6, each fixed slope sub-pixel 54 is in a non-rectangular parallelogram shape, and the extension direction of the long side of each fixed slope sub-pixel 54 is the same as that of the long side of any special-shaped edge sub-pixel 51.
Specifically, in the special-shaped display area 12, the sub-pixels which are not adjacent to the first edge 4 are also set as the sub-pixels with the same structure and the fixed slope of the extending direction as the special-shaped edge sub-pixels 51, so that more sub-pixels in the special-shaped display area 12 have the same display effect, and the display effect of the special-shaped display area 12 is improved.
Optionally, as shown in fig. 8, an irregular sub-pixel 55 is disposed between the fixed slope sub-pixel 54 and the second edge 6, the irregular sub-pixel 55 is adjacent to the second edge 6, the irregular sub-pixel 55 includes a third side and a fourth side, wherein the third side and the long side of the fixed slope sub-pixel 54 have the same extending direction; the fourth side extends in the same direction as the second edge 6.
Specifically, since the extending direction of the long side of the fixed slope sub-pixel 54 matches only the first edge 4 and does not match the second edge 6, in order to improve the display effect at the position between the fixed slope sub-pixel 54 and the second edge 6, the irregular sub-pixel 55 is disposed between the fixed slope sub-pixel 54 and the second edge 6, the third side of the irregular sub-pixel 55 is an edge far from the second edge 6, since the edge is close to the fixed slope sub-pixel 54, the extending direction of the third side is set to be the same as the extending direction of the long side of the fixed slope sub-pixel 54, the fourth side of the irregular sub-pixel 55 is a portion of the second edge 6, and the extending direction of the fourth side is set to be the same as the extending direction of the second edge 6 in order to match the second edge 6. By providing an irregular subpixel 55 between the fixed slope subpixel 54 and the second edge 6, the location between the fixed slope subpixel 54 and the second edge 6 can be matched to both the fixed slope subpixel 54 and the second edge 6. In addition, it should be noted that although the aperture ratio of the irregular sub-pixel 55 adjacent to the second edge 6 may change, the aperture ratio of the irregular edge sub-pixel 51 adjacent to the first edge 4 may not change, so that the structure shown in fig. 8 still has the effect of improving the color shift of the display screen at the irregular edge while reducing the jaggy feeling of the display screen at the irregular edge compared with the prior art.
Alternatively, as shown in fig. 9, fig. 9 is a top view of a partial region of another display panel in an embodiment of the present invention, and the second edge 6 is perpendicular to the second direction X, or, as shown in fig. 8, an included angle between the second edge 6 and the second direction X is an acute angle.
In particular, in the configuration shown in fig. 8, the second edge 6 is a profiled edge, whereas in the configuration shown in fig. 9, the second edge 6 is a non-profiled edge.
As shown in fig. 10, fig. 10 is a schematic structural diagram of a display device according to an embodiment of the present invention, and the embodiment of the present invention further provides a display device including the display panel 100.
The specific structure and principle of the display panel 100 are the same as those of the above embodiments, and are not described herein again. The display device may be any electronic device with a display function, such as a touch display screen, a mobile phone, a tablet computer, a notebook computer, or a television.
According to the display device in the embodiment of the invention, the special-shaped edge sub-pixel corresponding to the first edge in the special-shaped display area is set to be the non-right-angle parallelogram, so that the inclination degree of the corresponding special-shaped edge sub-pixel can be set according to the inclination degree of the first edge, and the inclination degree of the edge is close to that of the special-shaped edge sub-pixel, on one hand, when the inclination degree of the first edge is close to that of the special-shaped edge, the obvious sawtooth-shaped edge structure in the prior art is eliminated to a certain extent, and the sawtooth feeling of a display picture at the special-shaped edge is reduced; on the other hand, the aperture ratio of the sub-pixels at the special-shaped edges does not need to be changed, so that the color cast of the display picture at the special-shaped edges is improved while the saw tooth feeling of the display picture at the special-shaped edges is reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
