The difficulty is the need for separate growth and patterning of red-, green-, and blue-emitting organic EL materials [10] [13], which is mainly limited by the error of fabrication of the shadow mask and align between shadow mask and ITO glass. 2.2 Driving scheme of passive matrix OLEDs Many companies and institutes investigate driving technology and IC of OLEDs recently.
After depositing for organic materials, 10Å LiF and 1000 Å aluiminum layers were deposited one after another using the third mask (Mask 3) that had a full-screen-shape aperture.

Raw Materials and Methods Selected performance indicators in accordance with the "civilian airport asphalt concrete pavement construction technical specifications" (MH5011-1999) modified asphalt the SBS4303 additives (6%) and Shell matrix modified asphalt combination were be used to tests (Table 1).
(2)GW-944 to light having the effect of improving low temperature performance of SBS modified asphalt after aging, this may be due to the GW-944 does not absorb the light of any wavelength of more than 260 μm, it can not quench the excited state chromophore group, but a hindered amine in aabsorbing light energy in the state of oxygen, can be converted to the corresponding nitroxides, these nitroxides can capture not only the photooxidative degradation of polymer materials generated in the alkyl active radical, and having a light stabilization processregeneration function, thereby inhibiting the chain reaction to achieve the protective purposes.

The container's ability to withstand these compressive loads for sufficiently long periods depends on the material's characteristics as well as the container design.
The research presented herein tests the hypothesis that cumulative damage in the material under random dynamic compression will result in a reduction in the overall stiffness as well as an increase in the overall damping of the element.
These are expected to be manifested, respectively, as a shift in the fundamental resonant frequency as well as an increase in the bandwidth of the frequency response function of the material at resonance when configured as a single degree of freedom system.
The paper tests the hypothesis that cumulative damage in the material under random dynamic compression will result in a reduction in the overall stiffness as well as an increase in the overall damping of the structure.

Dynamic behaviour of bulk adhesives and other polymeric materials has been successfully investigated through a wide range of strain rates [2-4].
Experimental procedures Materials The adhesive used in this study, is the Araldite®2015 manufactured by Huntsman.
It is recommended for metals, glass/epoxy laminates and combinations of these kinds of materials.
Regardless the fact that the test does not involve a pure shear stress states within the adhesive, it is a simple and widely used geometry for joining materials.

In 1978, Joseph Davidovits, a French material scientist, had developed an amorphous three dimensional alumina-silicate materials, which he called ‘Geopolymer’.
Geopolymer is a new kind of inorganic material which resulted from polymeric reaction of alkaline liquid with silicon and aluminium in source materials [4].
The source materials can be of geological origin or by-product materials such as metakaolin, slag, fly ash and rice husk ash which is rich in silicon and aluminium content.
All the other materials are kept constant.
