Embodiment 1
A kind of pixel arrangement structure is provided in the present embodiment, be three-color pixel arrangement, the first pixel, the second pixel,
Third pixel is mutually different pixel, as shown in Figure 1, wherein the first pixel is red pixel, the second pixel is green pixel,
Third pixel is blue pixel.The pixel arrangement structure includes the pixel unit 1 of multiple repeated arrangements, each pixel unit 1
The first pixel 11, two including setting gradually the second pixel 12 close to each other, 21, third pixel 22, two described second
Pixel 12, the distance between 21 is less than the distance between second pixel 12,21 and rest of pixels.In other alternatives
In, different according to pixel arrangement mode, second pixel is also an option that as red pixel or blue pixel, the first pixel,
Third pixel is remaining two pixel, as long as the first pixel, the second pixel and third pixel all cover red, green, blue picture
Element.
As shown in Figure 1, in each pixel unit, between second pixel 12 close to each other, the second pixel 21
Distance is less than the distance between first pixel, 11 and second pixel 12, again smaller than between third pixel 22 and the second pixel 21
Distance.The sum of the width of two the second pixels 12, the second pixel 21 close to each other is approaching or otherwise approximately equal to the first pixel 11
Or the width of third pixel 22, ensure that the width of each pixel is almost the same in this way, to ensure that display effect.Due to two
Adjacent the second pixel 12, the second pixel 21 are the same pixel, therefore it can be closer to meeting wanting for technique when processing
It asks.So that the pixel arrangement structure can be even closer, the resolution ratio of pixel can reach higher.Pixel unit in often going
It is repeated in arrangement, forms the first pixel, two the second pixels, the loop distribution successively of third pixel.
As a preferred embodiment, in order to increase aperture opening ratio, display effect is improved, each pixel unit is non-in an adjacent row
Alignment, a kind of preferred mode are：With between the second pixel 12 adjacent thereto of first pixel 11 in a line
Gap corresponds to the third pixel 22 of the pixel unit in adjacent rows, which is generally higher than the width equal to third pixel.Equally,
First of the pixel unit in adjacent rows is corresponded to the gap between the second pixel 21 adjacent thereto of third pixel 22 in a line
Pixel 11, the gap also greater than or equal to the first pixel 11 width；With the first pixel 11 in a line it is adjacent with its described
Gap between three pixels 22 corresponds to two second pixels 12,21 of adjacent rows pixel unit, which is greater than or equal to
The sum of gap between second pixel 12, the width of the second pixel 21 and the second pixel 12 and two pixels 21.By above-mentioned straggly
The gap between pixel has been effectively ensured in the mode of distribution, ensures that the design margin of OLED in this way, increases R/G/B pictures
The aperture opening ratio of element overcomes the problem of ensureing pixel aperture ratio while can not improving resolution ratio in the prior art, to ensure
The aperture opening ratio of sub-pixel, improves light transmittance.
Two sub-pixels (such as G pixels) adjacent in a line are abutted in this programme, one pixel arrangement of adjacent line misregistration,
It can not only realize that sub-pixel and pixel circuit unit number reduced 1/3 in this way, but also can ensure OLED design margins, and increase R/G/
The aperture opening ratio of B sub-pixels.
In some specific embodiments, the first pixel 11 in pixel unit, the second pixel 12,21, third pixel
22 width is reasonably arranged according to the needs of resolution ratio, and concrete numerical value is needed according to technological ability and pre- development
Depending on PPI.For example, in a pixel unit, the distance between close to each other two described second pixels can be selected as 5 μm
~10 μm, first pixel is selected as 10 μm~30 μm with adjacent the distance between second pixel, the third picture
The distance between element second pixel adjacent thereto is 10 μm~30 μm.In above-mentioned preferred numberical range, it is seen that two phases
Mutually the distance between second close pixel is compared with distance between remaining pixel, and what can be arranged is more nearly, to make
The arrangement for obtaining pixel is compacter, and resolution ratio can be with higher.
As shown in Fig. 2, when PPI is about 518, distance a is 55.125 μm, and distance b is 49 μm, the width c of red pixel
It it is 10.5 μm, the height d of red pixel is 21 μm, and the width e of green pixel is 5 μm, and the distance between two green pixels f is
5 μm, distance g is 40 μm, and green pixel is 24 μm with adjacent blue pixel distance h, and distance i is 34.5 μm.The program exists
While realizing pixel compact arrangement, the whole spacing between pixel is also ensured, improve pixel aperture ratio.When resolution ratio is further
When increase, if PPI is about 518, when carrying out pixel arrangement using general fashion in the prior art, R/G/B pixel aperture ratios
About 1%/1%/2%, and after using the pixel arrangement structure Adjusted Option in the present embodiment, R/G/B aperture opening ratios are about
4.1%/3.9%/4.1%.As it can be seen that the pixel aperture ratio in this programme greatly improves.Therefore the pixel arrangement in the present embodiment
Structure can preferably take into account current Array and evaporation process is horizontal, realize that high-resolution is shown.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
