OLEDs (organic light emitting diodes) are more efficient and versatile than traditional lighting like incandescent bulbs and fluorescent bulbs. They are also brighter, faster, use less power than LCD displays, and are easier to fabricate than LEDs since they do not require crystals. The basic OLED has an anode, cathode, conductive layer, and emissive layer where holes move efficiently and excitons begin to form to produce light. Developments are being made in passive matrix, active matrix, transparent, top-emitting, flexible, and white OLEDs which could make displays thinner, lighter, more flexible, and brighter while using less power. Remaining challenges include lifetime, manufacturing processes, and susceptibility

OLED (organic light-emitting diode) is an emerging display technology that uses thin films of organic molecules to emit light when electricity is applied. Key advantages of OLEDs include thinner/lighter/more flexible displays without needing a backlight, as well as higher contrast ratios, brighter colors, and wider viewing angles. The first OLED device was developed in 1987, and now many companies are developing various OLED displays for applications like phones, TVs, and more. The basic structure of an OLED involves organic layers sandwiched between an anode and cathode, and different layer deposition and pixel approaches can generate red, green, and blue colors or white light.
Acrylic panel presentation 22 feb 2017
This document discusses the properties and uses of acrylic. It is a clear plastic material that resembles glass but is lighter, stronger, and more impact resistant than glass. There are two main types of acrylic: extruded and cell cast. Cell cast acrylic is of higher quality. Acrylic is commonly used in aquariums, swimming pools, water features, and architecture due to its clarity, strength, insulation properties, and ability to be shaped without seams. It has over 90% transparency and remains clear even when thick unlike glass which develops a green tint. Acrylic is also easier to work with than glass and has no size limitations.

Organic LED's
Organic LEDs (OLEDs) are a type of thin, lightweight LED that uses organic compounds that emit light in response to an electric current. OLEDs can be used for displays and solid state lighting applications. They have advantages over LCDs like being thinner, lighter, achieving higher contrast, and not requiring backlighting. OLEDs operate by using organic material layers, including an emissive layer, between an anode and cathode. When an electron and hole pair recombine in the emissive layer, a photon is released, emitting light. Research is focused on improving the lifetime of blue organic films and reducing production costs.
Oledtechnology in trends
Self-emissive organic light-emitting diodes (OLEDs) are a new promising technology with
high expected profitability on the display market, which is currently dominated by liquid
crystals. They show low driving voltages in combination with unrestricted viewing angles,
high color-brilliance, light weight, small film-thicknesses and low production costs. Because
of the plasticity of the materials they can be deposited on flexible substrates. Nowadays, there
are already OLED-display devices available such as PDAs, mp3 players, mobile phones,
navigation-systems etc. One can distinguish two material-classes used in OLED: OLEDs
based on small molecules, which are deposited by thermal evaporation and the low-cost
polymeric OLEDs, which are processed from solution. Initially, it was difficult to realise
polymeric multilayer OLEDs, since newly deposited layers dissolved the underlying layers,
but are now easily accessible by the use of direct lithography in combination with oxetanefunctionalised
polymers.
Despite intense research efforts during the last decade there are still improvements to be made
in OLED-lifetime and OLED-outcoupling. The light-outcoupling is limited by the refractive
indices of the OLED building layers. Simple ray-optics allows to estimate the external
quantum efficiency of a standard OLED to 20 % of the initially generated light. 80 %,
however, are lost to total internal reflection. To overcome this problem many approaches have
been introduced. They can be divided into modifications of the external OLED-architecture
(e.g. mesa structures, micro-lenses) and modifications of the internal layer structure. It was
demonstrated that diffraction elements, such as periodic structures, are highly suitable to
improve light-outcoupling. Doubling of the efficiency and luminescence enhancements up to
factors of five were reported with respect to the flat reference devices, but only in
combination with very poor overall efficiencies.
Subject of this thesis was to structure well-performing organic OLED-polymers by direct
lithography (DL) and investigate their applications in electro-optic devices as diffraction
elements. Additionally, photoembossing (PE) should be applied to access structured wellperforming
oxetane functionalised OLED-materials without any wet-development step. The
third method is a combination of direct lithography and photoembossing and is referred to as
“combined DL-PE structuring” in this thesis

Organic Light Emitting Diode or OLED
An OLED is a solid state device or electronic device that typically consists of organic thin films sandwiched between two thin film conductive electrodes. When electrical current is applied, a bright light is emitted. OLED use a carbon-based designer molecule that emits light when an electric current passes through it. This is called electrophosphorescence. Even with the layered system, these systems are thin . usually less than 500 nm or about 200 times smaller than a human hair.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
