7. Introduction
The transparent conducting oxide (TCO) is widely used as
oxide material
Both properties optically transparent & electrically conductive
in a same material is contradictory
TCO in transparent electronics are In2o3 , zno and Cdo
16. Transparent thin film transistor
Special kind of field-effect transistor
TTFTs fabricated to gate using conventional TOSs are SnO2
and Zno
A single crystalline film of the TOS InGaO3 is used for active
channel layer
For fabricating TTFT the RSPE method
17. Transparent UV detector
UV radiation wavelength 280-400 nm
UV detectors have developed using pn or schottky-junction of
wide band gap semiconductor such as GaN, ZnSe,ZnS and
diamond
It was fabricated using a pn-heterojunction diode composed
of p-type NiO
18. Applications
OLED display
WORKING OF OLED
TYPES OF OLED
1. Passive-matrix OLED
2. Active-matrix OLED
3. Transparent OLED
4. Top-emitting OLED
5. Foldable OLED
6. White OLED
Transparent solar panel
25. White OLED
Have true-color qualities of incandescent lighting
Their use could potentially reduce energy costs for lighting
26. Advantages of OLED
Organic layers of an OLED are thinner , lighter and more
flexible
Substrates of an OLED can br flexible instead of rigid
OLEDs are brighter
OLEDs are easier to produce and can be made to large and
thin sheets
These have large fields of view, about 170 degrees
27. Disadvantages of OLED
Lifetime-
1. red and green OLED –46,000 to 230,000 hours
2. Blue organics –up to around 14,000 hours
Manufacturing processes are expensive
Water can easily damage

36. conclusion
Transparent electronics having the combination of two
properties that are optically transparent and electrically
conductive gives lots of advantages such as high mobility, low
processing temperature , high performance and flexibility which
indicates our improved technology
