electron composed of metal
Anode : injecting hole composed of transparent ITO
Emissive polymer : recombination between hole and electron
Conducting Polymer : transporting holes
For many reasons; Less weight, flexible, fast response, lower power consumption and wide viewing angle OLED is very useful device for improving quality of human being, but still there are problems…

: 열전자를 방출하는 텅스텐 필라멘트의 수명을 길게하고, Target 표면의 오염을 방지하기 위하여, 내부는 고진공으로 되어있다.

: 전자가 가지고 있는 Energy의 0.1% 정도는 X선으로 변환 되지만, 대부분은 열로 변환되어 없어진다. 이러한 이유로 Target 표면을 물로 냉각시킨다.
angle
Viewing angle is the range of oblique angle which we can see the normal screen. Unlike LCD, the image quality doesn't change though it is seen from just beside.
6. Fast response speed
If we play moving images, the quality of the screen is determined by the response speed. OLED shows natural screen of the moving images which have the similar level with that of the television.
7. High col
First, Substrate is consists of a plastic or glass, a portion of the OLED is supportive.Anode is a role that make electron holes when current flows by removing electron. And the upper Conducting Layer is the place that Electron Holes is being created.Emissive Layer is the place accepting an electron from Cathode and produce light.
Emissive layer and conducting layer are called organic layer beca
CRT
* Large viewing angle
* High color contrast level
* Better resolution with moving
images
BUT!
Nowadays,
Portability & mobility is
important!!
CRT is too HEAVY to carry on +
Consumes more energy
LCD
* Narrow viewing angle
* Long response time
* Limited brightness
(because it use Backlight)
PDP
* Low luminous efficiency
So, We nee
on their PC’s.
The fastest LCD’s offer a response time of about 25 milliseconds as apposed to CRT’s that have a response time of about 13 milliseconds.
Price
The Cathode Ray Tube monitors have lower price rate than the LCD display or Plasma display.
Viewing Angle
Look at a very wide angle
Bulky and heavy sets
Takes more desktop space and heavy to pick up
and carry on
which correspond to the following conditions
1. The angle of incidence = angle of scattering.
2. The pathlength difference is equal to an integer number of wavelengths.
- Aluminum oxide
Electrical insulator
relatively high thermal conductivity
Trigonal, hR30
- Applications
Refractories, ceramics, polishing
Health and medical applications
Hard protective coating.
