बेन्डेबल र फोल्ड गर्न मिल्ने इलेक्ट्रोनिक उपकरणहरू

इन्जिनियरहरूले पातलो लचिलो हाइब्रिड सामग्रीबाट बनेको अर्धचालक आविष्कार गरेका छन् जुन निकट भविष्यमा इलेक्ट्रोनिक उपकरणहरूमा प्रदर्शन गर्न प्रयोग गर्न सकिन्छ।

Engineers at large corporations have been eyeing to design a foldable and flexible display screen for electronic उपकरणहरू like computers and mobile phones. The goal is a display screen which would feel like a paper i.e. be bendable but also function electronically. Samsung, one of the largest mobile phone manufacturers in the world will in all probability be launching a flexible mobile phone very soon. They have developed a flexible जैविक light emitting diode (OLED) panel which has an unbreakable surface. It is lightweight but tough and robust and can withstand high temperatures. Its most remarkable feature would be that this display will not break or be damaged if the device falls – the biggest challenge faced today by mobile phone display designers. A regular LCD screen continues to display even when bent but the liquid inside it becomes misaligned and hence a distorted image is displayed. The new flexible OLED screen could be bent or curved without distorting the display, however, it still won’t be completely foldable. The flexibility can be further increased by using more flexible nanowires in the future. A quantum dot light emitting diode display is more flexible because of the use of nano-crystals to produce high-quality sharp light. The displays still have to be encapsulated into glass or other material for protection.

लचिलो स्क्रिनहरू निर्माण गर्न नयाँ सामग्री

हालै प्रकाशित एक अध्ययनमा विकसित सामाग्री engineers from The Australian National University (ANU) have for the first time developed a semiconductor made from जैविक and inorganic material which efficiently converts electricity into light. This semiconductor is ultra-thin and very flexible making it unique. The जैविक part of the device, an important part of the semiconductor has a thickness of only one atom. The inorganic part is also small, about two atoms thick. The material was constructed by a process called ‘chemical vapor deposition’, similar to building a 3-dimensional structure from a 2D description. The semiconductor cannot be seen with naked eye, it rests between gold electrodes on a chip of size 1cm x 1cm having a functional transistor. One such chip can hold thousands of transistor circuits. The electrode serves as electricity input and output point. Once constructed opto-electronic and electrical properties of the material were characterized. This hybrid structure of जैविक and inorganic components converts electricity into light which then provides display on mobile phones, televisions and other devices. The light emission is seen to be sharper and better for higher-resolution displays.

यस्तो सामग्री निकट भविष्यमा उपकरणहरू झुकाउन योग्य बनाउन प्रयोग गर्न सकिन्छ - उदाहरणका लागि मोबाइल फोनहरू। मोबाइल फोनहरूमा स्क्रिन वा डिस्प्ले क्षति धेरै सामान्य छ र यो सामग्री उद्धार गर्न आउन सक्छ। ठूला स्क्रिन भएका स्मार्ट फोनहरूको लोकप्रियता र माग बढ्दै गएपछि डिस्प्लेमा खरोंच वा भाँच्ने वा खस्ने जस्ता समस्याहरू नहुने गरी स्थायित्व हुनु अहिलेको आवश्यकता हो। हाइब्रिड संरचना परम्परागत अर्धचालकहरूको तुलनामा दक्षताका दृष्टिले फाइदाजनक छ। पूर्ण रूपमा सिलिकन बनेको। यो सामग्री मोबाइल फोन, टेलिभिजन, डिजिटल कन्सोल आदिका लागि स्क्रिनहरू निर्माण गर्न प्रयोग गर्न सकिन्छ र एक दिन कम्प्युटरहरू बनाउन वा मोबाइल फोनलाई सुपर कम्प्युटर जस्तै बलियो बनाउन प्रयोग गर्न सकिन्छ। अन्वेषकहरूले पहिले नै यो सेमीकन्डक्टरलाई ठूलो मात्रामा उत्पादन गर्न काम गरिरहेका छन् ताकि यसलाई व्यवसायीकरण गर्न सकिन्छ।

इलेक्ट्रोनिक फोहोर व्यवस्थापन

It is estimated that 2018 will be produce a total of almost 50 million tons of electronic waste (e-waste) and very limited quantity would be recycled. E-waste constitutes electronic devices and equipment which have reached the end of their life and need to be discarded including old computers, office or entertainment electronic equipment, mobile phones, television etc. Massive amount of e-waste is a huge threat to the environment and is bound to cause irreversible damage to our natural resources and surroundings. This discovery is a starting point for designing electronic devices exhibiting high performance but which are made from जैविक ‘bio’ materials. If mobile phones were made of a flexible material they would be easier to recycle. This will cut down on e-waste generated annually across the globe.

फोल्डेबल र लचिलो इलेक्ट्रोनिक उपकरणहरूको भविष्य धेरै रोमाञ्चक हुन गइरहेको छ। इन्जिनियरहरू पहिले नै रोल गर्न मिल्ने डिस्प्लेको बारेमा सोचिरहेका छन् जहाँ उपकरणहरू स्क्रोल जस्तै रोल अप गर्न सकिन्छ। सबैभन्दा उन्नत प्रकारको डिस्प्ले स्क्रिन हो जुन फोल्ड, कर्भ वा कागज जस्तै क्रस गर्न सक्छ तर सफा छविहरू प्रदर्शन गर्न जारी राख्न सक्छ। अर्को क्षेत्र 'अक्सेटिक' सामग्रीको प्रयोग हो जुन तान्दा बाक्लो हुन्छ र जसले उच्च ऊर्जा प्रभावहरू अवशोषित गर्न सक्छ र कुनै पनि विकृतिलाई सच्याउन आत्म-पुनर्प्राप्त गर्न सक्छ। त्यस्ता उपकरणहरू हल्का तौल तर लचिलो हुनेछन्।
