The volume of 4 μm of half in 10.
Based on this, Fig. 7 shows printing quantum dot ink in the region defined by pixel defining layer 10 and scattering unit 20
Water 300 is the status diagram of quanta point material solution.According to technological requirement, quantum dot ink 300 and pixel defining layer 10
Contact angle needs to be more than 120 °, could accommodate more inks in this way.With 80ppi (pixels per inch, per inch pixel
Quantity) for sample, Fig. 7 is the schematic cross-section of sample short side, and the height by entire ink droplet known to approximate calculation is about 8 μ
M, body usually not more than 5%, the thickness of dry film is about 3~4 μm in the case.In view of in dispersing lens 200
Sunk part, therefore it is, for example, 2 μm that thickness of dry film also outline, which is less than 3~4 μm,.On this basis, as shown in figure 8, due to dissipating
The bosom of sunk area in lens 200 is penetrated up to 4 μm, therefore actual 30 thickness of dry film of quanta point material layer can in thickness
Up to 6 μm, and it is about 2 μm in thin location.
