(Small Molecule Organic Light Emitting Diode, OLED) and high-molecular luminous material organic light emission
Diode (Polymer Light Emitting Diode, PLED).Two kinds of row materials all have the chemical constitution and height of conjugation
Fluorescent efficiency, but both molecular weight difference it is quite big, the molecule of small molecule material used in small molecule Organic Light Emitting Diode
Amount is about hundreds of, and high polymer material molecular weight used in macromolecular Organic Light Emitting Diode about tens thousand of to millions of.Small point
Sub- material is the hot evaporation that organic material is carried out with the collocation of vacuum system and vapor deposition mask (Shadow Mask) in technique
(Vacuum Thermal Evaporation,VTE).And high polymer material is with solution rotating coating method or ink jet printing
Among material is scattered in pixel by (Ink Jet Printing) technology, its film forming procedure does not need vacuum environment, equipment cost
It is relatively low.High polymer material is adapted to large area, mainly makees the application of large-sized monitor, but small molecule material film forming compared with
It is good, it is adapted to the product of development high-order, mainly makees the application of medium and small-sized display.
Exemplified by redgreenblue material is deposited and makes OLED three RGB sub-pixels (subpixel) independently to light.
Figure 1A~1C is refer to, it is illustrated in the schematic diagram that Organic Light Emitting Diode material is deposited in a vacuum system.Above and below diagram
Part is respectively top view and profile.Mainly via vacuum thermal evaporation (VTE) mode, then arrange in pairs or groups and put on a substrate 11
Luminous organic material 15 is deposited to specific region the technology for putting a shade 12.As shown in Figure 1B, one is placed at a substrate 11
Shade (Shadow Mask) 12, due to being usually to make shade (Shadow using the metal material of low thermal coefficient of expansion (such as)
Mask), therefore also known as metal cover (Metal Mask) or fine metal shade (Fine Metal Mask, FMM).Shade 12
E.g. on a sheet metal utilize electroforming or etching formed a specific pattern (the opening 12a of array in such as figure), and this gold
Metal thin plate is welded on a metal framework (frame) 13.When red, blue, green one of which organic material is deposited, shade 12 is utilized
The location of pixels of two other color is covered, such as opening 12a (Figure 1B) positions on shade 12 and red pixel location pair
Should, vapor deposition source 14 has red luminous organic material, after red luminous organic material is deposited to opening 12a, then completes red
The luminous organic material 15 of color pixel position makes (Fig. 1 C).Then the alignment system movement shade 12 or base of high precision are utilized
Plate 11, it is further continued for the evaporation of next group of colored pixels.
When tradition is made in a manner of being deposited, the corresponding sub-pixel position of an aperture position on shade, therefore product
Resolution can be limited to FMM technological abilities.
When making the panel of high precision, because pixel and spacing all diminish, therefore the precision of alignment system, shade
Error and shade the opening obstruction of opening size and pollution are all crucial.Which kind of whether above-mentioned sub-pixel arrangement mode, it is limited
In FMM technological abilities, when tradition is made in a manner of being deposited at present, the corresponding sub-pixel market production of an aperture position on shade
Product highest resolution about 300PPI or so.
