Display panel, and calculation amount is small, can complete before shipment, and the driving chip resource for being not take up display panel can drop
The power consumption of low display.It is specific:
Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7 are please referred to, Fig. 3 is the signal of the special-shaped display panel of the application one embodiment
Figure；Fig. 4 is the processing method flow diagram of the special-shaped display panel of the application one embodiment；Fig. 5 is not using the application
Border processing method special-shaped display panel edge schematic diagram；Fig. 6 is aobvious using the abnormity of the border processing method of the application
Show face plate edge schematic diagram；Fig. 7 is the partial enlargement diagram of the special-shaped display panel of Fig. 3 embodiment.
In one embodiment of the application, the border processing method of special-shaped display panel, comprising:
S1: according to the shape of the target viewing area 100 of the display panel by the edge 110 of the display panel viewing area
It is fitted to function f (x)；
S2: d pixel is set in each pixel；Wherein, d >=4；
S3: judge the number c of the pixel in each pixel in fitting function f (x)；
S4: penalty coefficient k is generated, wherein k=c/d；
S5: edge-smoothing coefficient is generated according to penalty coefficient.
It is illustrated by taking " heart " display panel shown in Fig. 3 as an example below,
S1: the shape of the target viewing area of special-shaped display panel according to Fig.3, by the viewing area 100 of display panel
Edge 110 be fitted to function f (x), need name is that target viewing area refers to the viewing area obtained desired by us, or
Say be customer requirement viewing area 100.Regard the marginal portion of viewing area 100 as curve, a coordinate system is established, in coordinate
By curve matching at function in system.Certainly " heart " display panel shown in Fig. 3 is fitted to a function can be relatively difficult, institute
It can be piecewise function with the fitting function f (x) in the present embodiment.
S2: referring to FIG. 4, Fig. 4 is the partial enlarged view at the edge Fig. 3 111.D pixel is set in each pixel 12
120；Wherein, d >=4；The present embodiment is arranged that be more than or equal to 4 pixels be edge in order to realize homogenization in each pixel
Transition.Certainly, the more transition of the number of pixel 120 are about smooth.Inventor has found that pixel 120 is greater than after many experiments
It is then sufficient in the case where distance (distance of eye distance display panel is more than 15cm) normally observed when equal to 4
Enough is uniform.That is when viewing distance is 15cm, ordinary consumer is able to observe that 3 pixels and 4 pixels
The difference of obtained edge-smoothing effect, but can not almost discover 4 pixels and 5 obtained edges of pixel are flat
The difference of sliding effect, therefore the number of pixel 120 is scheduled on more than or equal to 4 by inventor.It should be noted that picture here
Element can refer to the sub-pixel group by different colours at " white pixel ", such as tri- sub-pixels of RGB in the arrangement of non-rendered pixel
Form one " white pixel "；Either RG or RB or GB forms one " white pixel " in rendered pixel arrangement, here
" white pixel " needs to borrow the color lacked to the sub-pixel on side, in conclusion pixel here also refers to display figure
The unit pixel of a pixel in piece.When pixel 12 of the unit pixel as the application, calculation amount is relatively low, and efficiency compares
It is high.Certainly, pixel described in the application also also refers to sub-pixel, when the application sub-pixel is as pixel described in the application
When 12, the precision that edge is adjusted is higher, and the effect of edge-smoothing is more preferable.
S3: how much is the judgement brightness reduction of the present embodiment most critical.By judging position in each pixel 12 in the present embodiment
In the number c of the pixel 120 in fitting function f (x).Because fitting function f (x) is the edge according to target viewing area
110 determinations.It is desirable that be viewing area edge in shine and do not shine outside edge.In other words, if pixel 120
It then needs to shine positioned at being located in fitting function f (x), is located at fitting function f (x) and does not need then to shine outside.But actually like
Element is an entirety, can not accomplish that the luminous half of half does not shine, therefore, the application pixel 120 is located in pixel
Number come represent pixel should how many region should shine.Further it is compensated.It should be noted that this implementation
It is located in fitting function f (x) described in example and refers in viewing area.
S4: penalty coefficient k is generated, wherein k=c/d；According to the theory of front it is found that is obtained is located at fitting function f (x)
What the number of interior pixel 120 represented is the region that shine, the region by that should shine and total light emitting region
Ratio determines penalty coefficient.Here the number for the pixel that the number of the pixel 120 in fitting function f (x) can be total
Ratio can represent this penalty coefficient.Accordingly, it is determined that penalty coefficient k=c/d
S5: edge-smoothing coefficient is generated according to penalty coefficient k.The area that should be shone due to the principle of penalty coefficient k=c/d
The ratio in domain and total light emitting region, this ratio and brightness are substantially that linear relationship is presented.And last edge-smoothing coefficient
It is applied on gray scale voltage, gray scale voltage and brightness are not linear relationships.Therefore, most accurate edge is flat in order to obtain
Sliding coefficient cannot say that penalty coefficient k is directly equal to edge-smoothing coefficient, but need penalty coefficient k being mapped to edge-smoothing system
Number K '.
The edge 110 of target viewing area 100 is fitted to function f (x) in the present embodiment, to be not limited to radii fixus
Or the special-shaped edge of curvature, substantially increasing processing method is applicability.Also, by the way that pixel 120 is set greater than
Equal to 4, guarantee the smooth transition at edge.In addition, the border processing method of the present embodiment can be completed on computers completely, it is whole
A edge processing process is completed before factory, small for the occupancy and calculation amount of the resource of driving chip (IC), can be reduced
The power consumption of driving chip.Fig. 5 and Fig. 6 are please referred to, Fig. 6 is the display effect mould after the border processing method for applying the present embodiment
Quasi- figure.Fig. 5 is the display effect simulation drawing of the border processing method of unreferenced the present embodiment.It can be seen that the edge of Fig. 5 looks at
Sawtooth is serious, seems stair-stepping edge.And compared with Fig. 5, it can be seen that its edge realizes multistage smooth place in Fig. 6
Reason, edge seem that nature is smooth, are more like a circular arc.
Further, in one embodiment of the application, the border processing method of special-shaped display panel is specifically included:
S1: according to the shape of the target viewing area 100 of the display panel by the edge 110 of the display panel viewing area
Function f (x) is fitted to specifically include:
Determine in plane to be some coordinate origin O；,
The irregular shaped region of the edge of display area 110 of the display panel is segmented；
It is piecewise function f (x) by edge fitting；
It should be noted that the difficulty of the possible influence function fitting of the selection of coordinate origin O, by taking Fig. 3 as an example, the display surface
The edge 110 of plate can be divided into two sections of elliptic curves, the function f if coordinate origin selection wherein an elliptical center
(x) relational expression will become simple.The selection of coordinate origin o can according to need determination.By the display in Fig. 3 embodiment
The edge 110 of panel is divided to for two parts, fits function f1 (x) and f2 (x) respectively, is greatly lowered the difficulty of fitting in this way
Degree.It, can be with it should be noted that the coordinate system that the application can establish is not limited to the present embodiment disclosed cartesian coordinate system
It is polar coordinates etc..Some curve polar coordinates can substantially reduce the complexity of its functional relation, advantageously reduce computer
Workload, and can make fitting curve it is more accurate.
S2: d pixel is set in each pixel；Wherein, d >=4；Please continue to refer to Fig. 8, Fig. 9 and Figure 10, Fig. 8 is
A kind of partial approach schematic diagram of the special-shaped display panel of Fig. 7 embodiment；Fig. 9 is the another of the special-shaped display panel of Fig. 7 embodiment
A kind of partial approach schematic diagram；Figure 10 is another partial approach schematic diagram of the special-shaped display panel of Fig. 7 embodiment；
The coordinate of each pixel 120 is Ai(xi, yi), the positive integer that i is 1 to d, the d pixel be uniform
Distribution；The geometric center for being uniformly distributed the geometric center and the pixel that surround figure for the d pixel substantially weighs
It closes.As shown in figure 8, including 4 pixels 120 in each pixel 12, the coordinate of a pixel 120 is respectively A1(x1, y1), A2
(x2, y2), A3(x3, y3), A4(x4, y4), roll over 4 besieged city of pixels 120 rectangles, the geometric center S ' and pixel 12 of this rectangle
Cluster center S substantially overlap.It may insure that pixel is uniformly distributed in pixel in this way, obtained penalty coefficient k can
The more smooth transition in the edge for being.
Further, referring to FIG. 10, in order to enable the transition at edge can more smoothly surround the d pixel
The geometric center of the pixel rotates angle, θ；Referring to FIG. 8, the A in reference axis before rotation3A4It is parallel to x-axis, is being rotated
Its angle presented with x-axis is θ later.Abscissa of the pixel 12 that square represents in x-axis is located in range [m, n].It is public
Formula 0.5*f ' (z)≤tan θ≤2f ' (z), wherein the meaning of z ∈ [m, n] is that the fitting function f (x) being located in pixel 12 exists
The tangent slope at the interior any point coordinate [m, n] is f ' (z), the tangent value and any point tangent line and x-axis angle of rotation angle θ
Tangent value meet above-mentioned relation.That is, the tangent value of rotation angle θ is more than or equal to fitting function f (x) for being located in x ∈ [m, n]
Any point tangent line and x-axis angle tangent value minimum value half；The tangent value of rotation angle θ is less than or equal to fitting
Function f (x) is for the tangent line of any point in x ∈ [m, n] and twice of the maximum value of the tangent value of x-axis angle.It is above-mentioned
Relationship is substantially to define in rotation angle θ and pixel 12 between the tangent line of f (x) and the angle maximum value and minimum value of x-axis
Relationship.Please further refer to Figure 10, the area for being located at fitting function f (x) lower zone is about the 1/4 of entire 12 area of pixel
Left and right, if pixel 120 is not rotated, the number for obtaining the pixel in fitting function f (x) should be 2, generate
Penalty coefficient k should be k=2/4, this be located at 1/4 differing greatly for f (x) area under substantially 12 area of pixel, meeting
Cause edge transition more stiff, unnatural situation occurs.And according to the method for the present embodiment, referring to FIG. 10, in pixel
It is 1 that pixel 120 in 12, which is located at the number in fitting function f (x), and the penalty coefficient k of generation should be k=1/4, this
It is 1/4 consistent be located at f (x) area under substantially 12 area of pixel, so that the edge transition of the application is more natural.
In another embodiment of the application, the d pixel is surrounded to the geometric center rotation angle of the pixel
θ is spent, determines rotation angle, θ by emulating in advance.It, can be by pre- imitative in order to obtain the significantly more efficient method for obtaining rotation angle θ
Really choose optimal rotation angle, θ.Multiple rotation angle θs specifically can be set, then emulation obtains the effect picture of edge processing,
Then the edge processing that rotation angle θ does final display panel is chosen according to effect picture.
Further, this border processing method can be greatly increased if each pixel sets corresponding rotation angle
Calculation amount wastes time to reduce efficiency.Under the precondition for ensuring edge-smoothing transition, inventors have found that by the edge
Fitting function f (x) carries out being divided into rotation group according to tangent slope, and each rotation group can also reach side using identical rotation angle
The smooth transition of edge.Further, in order to reduce calculation amount, the sum of rotation group is no more than 8 groups.
S3: judge the number c of the pixel in each pixel in fitting function f (x)；
It is another place's partial enlargement of the special-shaped display panel of Fig. 3 embodiment please further refer to Figure 11 and Figure 12, Figure 11
