Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.Many details are explained in the following description in order to fully understand this hair
It is bright.But the invention can be embodied in many other ways as described herein, those skilled in the art can be not
Similar improvement is done in the case where violating intension of the present invention, therefore the present invention is not limited by the specific embodiments disclosed below.
Fig. 1 shows one embodiment of the present of invention: display screen includes substrate 100 and the pixel limit on substrate 100
Given layer 200, the support column 300 in pixel confining layer 200.Wherein, substrate 100 includes the flexible substrate of lamination formation
101, buffer layer 102, TFT (thin film transistor (TFT)) layer, interlayer insulating film 103 and planarization layer 104.Pixel confining layer 200 limits
It is multiple for accommodating the pits 202 of light emitting pixel.Light emitting pixel can be formed in the pit 202 by the methods of vapor deposition.
There is support column 300 in pixel confining layer 200.Support column 300 far from pixel confining layer 200 surface on,
Support column 300 also has stress dispersion slot 302.I.e. stress dispersion slot 302 is opened on support column 300 far from pixel confining layer 200
Surface, and to 200 direction of pixel confining layer extend.The formation of stress dispersion slot 302, which can make support column 300 form one, to be had
Conducive to the shape of stress dispersion, so that stress dispersion slot 302 can correspond to when the support column 300 of display screen is by stress
Power is dispersed, to avoid display screen since stress concentration is damaged, promotes the display quality and display effect of display screen.
In one embodiment, the concrete shape of support column 300 can be as shown in Figure 2.In the embodiment, support column 300
With identical first protrusion 310 of height and the second protrusion 320.When carrying out the vapor deposition of light emitting pixel to display screen, identical height
The first protrusion 310 and the second protrusion 320 of degree can support Vapor deposition mask plate simultaneously, thus guarantee to support the steady of mask plate,
Guarantee evaporation effect.The height of stress dispersion slot 302 is lower than the first protrusion 310 and the second protrusion 320 and is located at the first protrusion 310
And second between protrusion 320.I.e. due to the formation of stress dispersion slot 302, forming support column 300 has mutually level first
Protrusion 310 and the second protrusion 320.
First protrusion 310 and the second protrusion 320 should be obliquely installed relative to the direction of vertical pixel confining layers.It can be as
Shown in Fig. 2, on longitudinal profile, the two sidewalls of the first protrusion 310 are tilted to the direction far from the second protrusion 320；Second protrusion
320 two sidewalls are tilted to the direction far from the first protrusion 310.At this point, stress dispersion slot 302 is opened in 310 He of the first protrusion
Between second protrusion 320, the dispersion to stress is realized with inclined first protrusion 310 and the second protrusion 320, to increase support
Column 300 promotes the display quality and display effect of display screen to the peptizaiton of stress.
In this embodiment, when support column 300 is by external force straight down, stress is divided through support column 300
After dissipating, the direction of power is as shown in Figure 3.It can be seen from the figure that after external force F1 straight down acts on support column 300 originally,
It is separated into the power F1 and F2 of two difference to the left and right sides, has achieved the effect that stress disperses.
In one embodiment, after support column 300 forms stress dispersion slot 302, can make to support as shown in figures 2 or 4
First protrusion 310 of column 300 and the inclination of the second protrusion 320, and the first protrusion 310 is tilted to the direction far from the second protrusion 320,
Second protrusion 320 is tilted to the direction far from the first protrusion 310.At this point, the bottom end of the first protrusion 310 of support column 300 and
The bottom end of two protrusions 320 can be connected or be not attached to.As shown in Fig. 2, the bottom end of the first protrusion 310 and the second protrusion 320
It is not attached to, at this point, on longitudinal profile, support column 300 is in U-shape structure.It can also be as shown in figure 4, the first protrusion 310 and second be convex
The bottom end in portion 320 is connected, at this point, on longitudinal profile, the V-shaped structure of support column 300.
It in another embodiment, can be as shown in figure 5, the first protrusion 310 and the second protrusion 320 of support column 300 be inclined
Tiltedly, and the first protrusion 310 is tilted to the direction close to the second protrusion 320, hair of second protrusion 320 to close first protrusion 310
Now tilt.At this point, the stress dispersion slot 302 formed between the first protrusion 310 and the second protrusion 320 of support column 300 is one
Be open relatively narrow U-lag.Support column 300 is again formed as the relatively narrow U-shaped structure of opening.
, can also as is seen in fig. 6 or fig. 7 in having one embodiment, the first protrusion 310 and second of support column 300 is convex
Portion 320 tilts, and the first protrusion 310 and the equidirectional inclination in the second protrusion 320.At this point, 310 He of the first protrusion of support column 300
The stress dispersion slot 302 formed between second protrusion 320 is an inclined U-lag.Support column 300 is again formed as an inclination
U-shaped structure.In Fig. 6, the longitudinal profile of support column 300, the first protrusion 310 and the second protrusion 320 are tilted to the left.In Fig. 7,
The longitudinal profile of support column 300, the first protrusion 310 and the second protrusion 320 are tilted to the right.
The various embodiments described above list the structure of a variety of support columns 300, wherein the support column 300 of each structure can lead to
It crosses the first protrusion 310 being formed slopely and the second protrusion 320 and has the function that stress disperses, to alleviate display screen by outer masterpiece
A possibility that with being damaged.It is to be appreciated that above-described embodiment is only to the several of the shape of the support column 300 of the application
It enumerates, should not be construed as the restriction to the protection scope of the application.
In one embodiment, as shown in Fig. 2 to any one of Fig. 7, the support column 300 of above-mentioned display screen, longitudinal direction
On section, the first protrusion 310 is in up-narrow and down-wide shape, and the second protrusion 320 is also in up-narrow and down-wide shape.When support column 300
When being generated deformation by stress, wider bottom can promote the first protrusion 310 and the second protrusion 320 to resile, thus
Enhance the stability of the first protrusion 310 and the second protrusion 320, increases the stress dispersibility of support column 300, promote display screen
Display effect.
In one embodiment, as can be seen from figures 8 and 9, the support column 300 of display screen, the depth of stress dispersion slot 302
The range of H1 is seven ten ten to percent 3 the percent of the height H2 of support column 300.The depth H 1 of stress dispersion slot 302 both may be used
To be 30 the percent of 300 height H2 of support column, it is also possible to 70 the percent of 300 height H2 of support column, can also be
50 the percent of 300 height H2 of support column.
On surface of the support column 300 far from pixel confining layer 200, the width L1 range of stress dispersion slot 302 is support
Seven ten five 20 five to percent the percent of 300 width L2 of column.Stress dispersion slot 302 is in the width far from pixel confining layer 200
Spend L1 either 300 width L2 of support column 25 percent, be also possible to 70 the percent of 300 width L2 of support column
Five, it can also be 50 the percent of 300 width L2 of support column.Display screen in the embodiment, to the depth of stress dispersion slot 302
Degree and width are defined, so that stress dispersion slot 302 is while playing stress peptizaiton, it can also be ensured that support column
300 the first protrusion 310 and the support strength and stability of the second protrusion 320, to increase the stress resistivity of support column
And dispersibility, promote the display effect of display screen.
