First embodiment
Before introducing the dot structure of presently filed embodiment, first to the several normal pixels knot of the prior art
Structure is introduced as follows:
It is shown in Figure 1, a kind of original dot structure is disclosed in Fig. 1, and there is the first sub- picture successively side by side
Plain 1, second sub-pixel 2 and third sub-pixel 3, three sub-pixels respectively show a kind of color.
Obviously, this arrangement mode is easy to cause the color difference in transverse direction and longitudinal direction, it is also difficult to carry out effective
Pixel-expansion most importantly since the color on each perpendicular column is all consistent, exist when shown color
When changing on the direction of perpendicular column, therefore the luminous position of the second sub-pixel 2 is also deviated, and then lead to longitudinal direction on the screen
There is sawtooth in the display in direction.
Shown in Figure 2, the dot structure based on Fig. 1 has carried out the improvement of staggered.However, inclined direction still
There is a problem of identical, similarly likely results in the sawtooth of inclined direction, reduce display effect.In addition, such dot structure
It utilizes spatial area with being unable to fully, causes resolution ratio low.
Shown in Figure 3, the prior art additionally provides a kind of novel dot structure.It is sub by the first sub-pixel 1, second
Pixel 2 and third sub-pixel 3 constitute a basic pixel group c, the discrete space in pixel group c in a manner of isosceles triangle
It is interior.For first two technical solution, pixel group c is improved to the utilization rate of spatial area, so that display is differentiated
Rate has obtained certain promotion.However, the inventors of the present application found that the first sub-pixel 1 is in transverse direction in this dot structure
Be all on longitudinal direction it is dull duplicate, can still bring aliasing problems.
Shown in Figure 4, the dot structure based on Fig. 3 has carried out the improvement of staggered, overcomes the first sub-pixel 1 and exists
Dull replication problem in transverse direction, but the dull replication problem on longitudinal direction is not overcome still, therefore aliasing problems
Slight improvement is only obtained.
In view of this, the first embodiment of the application provides a kind of completely new dot structure, referring to Fig. 5, Fig. 6 institute
Show, dot structure may include:
There are two 1, two the second sub-pixel 2 of the first sub-pixel, two thirds for tool in multiple pixel group c, each pixel group c
Sub-pixel 3；
Wherein, there is first sub-pixel 1, second sub-pixel 2 and a third sub-pixel 3 are located at pixel group c's
Side, constitutes the first three primary colors unit a, remaining sub-pixel constitutes the second three primary colors unit positioned at the other side of pixel group c
b；
First sub-pixel 1 occupies one jiao of the first place three primary colors unit a side, the first son in the first three primary colors unit a
The first sub-pixel 1 in pixel 1 and the second three primary colors unit b central symmetry point using the center of pixel group c as symmetrical centre
Cloth.
For compared with the prior art, two the first sub-pixels 1, two are contained in the pixel group c of the application
Two sub-pixels 2 and two third sub-pixels 3.In each pixel group c, by the way that the first sub-pixel 1 is carried out central symmetry point
Cloth can be effectively prevented the dull replication problem of the first sub-pixel 1, and then reduce or even eliminate sawtooth.
Accordingly, optionally, the first sub-pixel 1 is strip, and the long side length of the first sub-pixel 1 is greater than the second sub-pixel 2
And/or width of the third sub-pixel 3 in the longitudinal direction of the first sub-pixel 1；
The longitudinal direction of first sub-pixel 1 is consistent with the longitudinal direction of pixel group c.
The space that pixel group c can be more fully utilized using one big two small pixel arrangement mode, improves resolution ratio.
The first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3 of the application meaning are in the case where being not particularly limited
It can be substituted for one another.But, due in existing technical conditions, under same electric current, the luminous effect of blue pixel
Rate is significantly lower than green and red pixel, and gap is very big, and it can be considered to increase the area of blue subpixels.Namely
It says, optionally, the first sub-pixel 1 is blue subpixels, and the second sub-pixel 2 is green sub-pixels, and third sub-pixel 3 is red son
Pixel.
Certainly, the second sub-pixel 2 and third sub-pixel 3 also can be interchanged, for example, be red by the second sub-pixel 2, and the
Three sub-pixels 3 are that green is also feasible.
In order to improve space utilization rate to a greater extent, in the first three primary colors unit a, the second sub-pixel 2 and third
Pixel 3 is abreast set to the side of the long side of the first sub-pixel 1 along the longitudinal direction of the first sub-pixel 1.It is on the other side,
In the second three primary colors unit b, the second sub-pixel 2 and third sub-pixel 3 equally can be along the longitudinal directions of the first sub-pixel 1
Abreast it is set to the side of the long side of the first sub-pixel 1.
In this application, not only the first sub-pixel 1 carries out central symmetry distribution, can also enable entire first three primary colors list
Mutual centre is symmetrical between first a and the second three primary colors unit b.Furthermore, it is understood that it is shown in Figure 5, the first sub-pixel 1
Distance of the long side length less than the second sub-pixel 2 and the most distal edge of third sub-pixel 3.In this way, which the one or three constituted is former
Color element a and the second three primary colors unit b are complimentary to one another in structure, can be bigger for each scheme compared with the prior art
Spatial area is utilized to degree, improves resolution ratio.
When mutual centre is symmetrical between the first three primary colors unit a and the second three primary colors unit b, in a pixel group
In c, it is close to each other to will lead to two the second sub-pixels 2, and two third sub-pixels 3 are away from each other.From the transverse direction of Fig. 5
It sees, may result in repeating close to dullness for second or third sub-pixel 3 in a lateral direction.
And further, it is shown in Figure 5, there can also be more preferably distribution scheme.Specifically, shown in Figure 5.
The line parallel with the long side of the first sub-pixel 1 that we can define the first three primary colors unit a is line of symmetry L；And enable second
Each sub-pixel in the arrangement mode of each sub-pixel in three primary colors unit b and the first three primary colors unit a is with line of symmetry L mirror image pair
Arrangement mode after title is identical.
In this way, from top to down, in a pixel group c, available second sub-pixel 2 and third sub-pixel 3
Put in order are as follows: third sub-pixel 3, the second sub-pixel 2, third sub-pixel 3, the second sub-pixel 2.And picture adjacent thereto
Element group c equally follows this arrangement, that is to say, that by the arrangement mode and for enabling each sub-pixel in the second three primary colors unit b
Each sub-pixel in one three primary colors unit a is identical with the arrangement mode after line of symmetry L mirror symmetry, can make the first sub-pixel
It 1, all will not be significantly in all directions such as lateral, longitudinal and oblique of the second sub-pixel 2 and third sub-pixel 3 spatially
Dullness repeatedly, has substantially prevented aliasing problems.
What is particularly worth mentioning is that even if the first three primary colors unit a is not present in structure between the second three primary colors unit b
Symmetric relation in addition the second sub-pixel 2 and the third sub-pixel 3 not side by side, also still can be realized the technology of the application
Purpose.Specifically, shown in Figure 7, in the first three primary colors unit a, the second sub-pixel 2 is located at relative to third sub-pixel 3
Close to the position at the center of pixel group c.Moreover, the second sub-pixel 2 is relative to third sub-pixel 3 in the second three primary colors unit b
It is located remotely from the position at the center of pixel group c.Arrangement using the arrangement of this form of Fig. 7, or based on this type it is some
Simple deformation, can substantially meet present invention purpose.
In conclusion the application optimizes the occupy-place of pixel spatially, reasonably the arrangement of each sub-pixel is matched
Than that can meet the light-emitting area of each sub-pixel to the full extent, guarantee the luminance proportion of light-emitting surface.The pixel of the application
Structure can take into account the sawtooth defect of the oblique line and camber line that are likely to occur during display, improve display resolution.
In addition, the dot structure of the application can also carry out resolution extension, to obtain the display effect of higher resolution
Fruit, specific extended mode and its advantages, will be illustrated in second embodiment.Second embodiment
Before introducing the dot structure resolution extension method of presently filed embodiment, first to extended method itself
One is done to be described below:
In Display panel field, there is the arrangement mode of " RGB arrangement " and " Pentile arrangement " two kinds of dot structures.
Those of ordinary skill in the art understand, for a light emitting pixel point, in order to realize that screen supports the full gamut in range
Color display, need the sub-pixel of blue, green and red three kinds of colors that can realize.Therefore, one is shown
For panel, " RGB arrangement " refer to coming using trichromatic sub-pixel as a basic pixel repetitive unit using
Arrangement.
By taking Fig. 8 of the application as an example, the dot structure of the application is can using the base pixel repetitive unit of " RGB arrangement "
To be P11, P12, P21 etc..Its picture element matrix are as follows:
As can be seen that the size in each pixel repetitive unit is identical, and the distribution of color of the sub-pixel in transition zone is
Complementation, therefore the dot structure of the application ensure that entire picture color homogeneity, while on oblique direction, the mistake of pixel
Degree is uniform, therefore sawtooth and color offset phenomenon are also unobvious.
Obviously, in any dot structure, there is optimal display effect using " RGB arrangement " is all opposite, but divide
Resolution size is just only original resolution sizes.In screen resolution higher and higher today, " RGB arrangement " is used merely
It may be insufficient for the high-resolution demand of small-size equipment.
In view of this, providing the pixel arrangements of entitled " Pentile arrangement " in the prior art, mainly pass through
The method of the adjacent public sub-pixel of pixel repetitive unit reduces the demand to the number of sub-pixel, to reach low resolution
Screen still there is the display effect close to high-resolution screen.
Moreover, permeability can also be increased using " Pentile arrangement ".Smaller function is only needed under same brightness
Consumption promotes cruising ability, can significantly reduce cost.
However, being limited to dot structure, the scalability of " the Pentile arrangement " of the prior art is poor, for example, for figure
1, for the dot structure in Fig. 2, do not have scalability substantially.For the dot structure of Fig. 3, Fig. 3, due to vertical
Upward two the first sub-pixels 1 are continuous, therefore are also difficult to carry out the good extension of display effect in the longitudinal direction.
In the present embodiment, based on dot structure given by the application, a kind of resolution extension method is provided.
Wherein, dot structure includes: multiple pixel group c, and there are two the first sub-pixels 1, two for tool in each pixel group c
Two sub-pixels 2, two third sub-pixels 3；
Wherein, there is first sub-pixel 1, second sub-pixel 2 and a third sub-pixel 3 are located at pixel group c's
Side, constitutes the first three primary colors unit a, remaining sub-pixel constitutes the second three primary colors unit positioned at the other side of pixel group c
b；
The first sub-pixel 1 in the first sub-pixel 1 and the second three primary colors unit b in first three primary colors unit a is with pixel
Center central symmetry distribution as symmetrical centre of group c；
One jiao of side where first sub-pixel 1 occupies the first three primary colors unit a, that is to say, that second, third sub-pixel 3
It can take up another angle in side where the first three primary colors unit a.In order to enable pixel light emission balances, the first sub-pixel can be enabled
1 is strip, and the longitudinal direction of the first sub-pixel 1 is consistent with the longitudinal direction of pixel group c.
In the first three primary colors unit a, the second sub-pixel 2 is located at relative to third sub-pixel 3 close to the center of pixel group c
Position；And in the second three primary colors unit b, second sub-pixel 2 is located remotely from relative to the third sub-pixel 3
The position at the center of the pixel group c.
The above are the basic demands of the dot structure for the resolution extension method for meeting the application, and in order to further mention
For display effect, the dot structure for meeting above-mentioned condition can carry out resolution extension.
And in order to further improve display effect, the longitudinal direction of the first sub-pixel 1 and the pixel group c can also be made
Longitudinal direction it is consistent；
In the first three primary colors unit a, the second sub-pixel 2 and the third sub-pixel 3 are along first sub-pixel 1
Longitudinal direction is abreast set to the side of the long side of first sub-pixel 1；Define the first three primary colors unit a with first son
The parallel line of the long side of pixel 1 is line of symmetry L, then the arrangement mode and the one or three of each sub-pixel in the second three primary colors unit b
Each sub-pixel in primary colors unit a is identical with the arrangement mode after line of symmetry L mirror symmetry.
In the present embodiment, resolution extension method may include following several:
