Description
Technical field
The present invention relates to technical field of manufacturing semiconductors, more particularly to a kind of OLED pixel arrangement architecture and display device.
Background technology
In recent years, Organic Light Emitting Diode（Organic Light-Emitting Diode, OLED）Because it possesses certainly
It is luminous, be not required to backlight, and contrast height, thickness of thin, visual angle is wide, reaction speed is fast, available for flexibility panel, use temperature
The excellent characteristics such as degree scope is wide, construction and processing procedure are simpler, it is considered to be the follow-on emerging application technology of flat-panel screens.
Organic light emitting display technology is made up of very thin coating of organic material and glass substrate, when have electric charge by when, these are organic
Material will light.Relative to LCD display, OLED has more power saving, thinner, and the advantage that visual angle is wide, and this is that LCD can not compare
Intend.OLED is divided into active OLED according to the difference of type of drive（AMOLED）With passive type OLED（PMOLED）.Relative to
PMOLED, AMOLED are because each pixel has independent pixel-driving circuit, so large scale can be realized, high-resolution,
Compared with power saving, the features such as panel lasts a long time.
It is red in OLED true color methods（R）, it is green（G）, it is blue（B）Three primary colors pixel juxtaposition (side-by-side
Pixelation it is) to develop most ripe technology.Usually, the sub-pixel of R, G, B tri- is planar alternately repeated arrangement, adjacent
Three sub-pixels form a pixel cell that can launch any color, i.e., basic elementary area, pixel cell is planar
Repeated arrangement forms display screen.The size of pixel is smaller, the resolution ratio of display, or PPI（Pixels Per Inch, often
The pixel that inch is possessed）It is higher, the more clear exquisiteness of picture of display.
The principal element for influenceing high PPI values is exactly the high-fineness of mask plate, due to mask plate（Mask）Aperture area has
Lower specification limit, and in order to avoid manufacturing process is by tolerance（tolerance）Influence, need between the opening of adjacent pixel pre-
Stay gap（gap）And cause picture element density small, cause PPI not to be increased dramatically.

Height, the efficiency and life-span highest of green material therefore, can be by changing between sub-pixel when designing elemental area and arrangement
Relative area carry out the influence that balancing material factor is brought；The area of blue light-emitting sub-pixel is maximum, and red is taken second place, and green is most
It is small.
In the present embodiment, first sub-pixel 101 is blue subpixels R, and second sub-pixel 102 is red sub- picture
Plain G, the 3rd sub-pixel 103 are green sub-pixels B.I.e. in the color alignment example, each base pixel unit includes 1
Individual blue subpixels, 1 red sub-pixel and 1/2 green sub-pixels.
In another embodiment, first sub-pixel 101 is red sub-pixel R, and second sub-pixel 102 is blueness
Sub-pixel G, the 3rd sub-pixel 103 are green sub-pixels B.I.e. in the color alignment example, each base pixel unit
Comprising 1 red sub-pixel, 1 blue subpixels and 1/2 green sub-pixels.
It should be noted that in above-described embodiment, the sub-pixel 102 of the first sub-pixel 101 and second is square,
3rd sub-pixel 103 is rectangle, and does not consider the first sub-pixel 101, the second sub-pixel 102 and the 3rd sub-pixel 103 3
The size of spacing and single sub-pixel between person.However, in the making of actual display panel, metal mask plate,
The apparatus and process such as the insulating barrier of pixel segmentation, the precision of plated film, and the factor such as material luminous efficiency, driving design, can all make
The about arrangement of pixel, the line space design between shape size, and sub-pixel.
Above-mentioned some factors are considered, the sub-pixel 102 of the first sub-pixel 101 and second is symmetrical five side
Shape, it will be understood that the shape of first sub-pixel 101, the second sub-pixel 102 and the 3rd sub-pixel 103 can also be triangle,
The polygons such as quadrangle, hexagon, heptagon, octagon.
The size of the first sub-pixel, the second sub-pixel and the 3rd sub-pixel can be with identical in the present invention, can also not
Together.In the present embodiment, the first sub-pixel 101 positioned at the virtual octagon OC centers（Blue subpixels B）Area it is maximum,
Second sub-pixel 102（Red sub-pixel R）Area take second place, the 3rd sub-pixel 103（Green sub-pixels G）Area
