Seoul firms unveil rare-earth-free white LED chip, shares hit daily limit

سیول کی کمپنیوں نے نایاب معدنیات کے بغیر سفید ایل ای ڈی چپ متعارف کرا دی، حصص روزانہ کی حد تک پہنچ گئے

सियोल की कंपनियों ने दुर्लभ खनिजों के बिना सफ़ेद एलईडी चिप पेश की, शेयर दैनिक सीमा तक पहुँचे

Seoul firms unveil rare-earth-free white LED chip, shares hit daily limit

Key points

اہم نکات

मुख्य बातें

  • Seoul Viosys and its parent Seoul Semiconductor have developed an ultra-small LED chip called WICOP3 that produces white light without rare earths, and shares in both companies hit their daily upper price limit on October 29.
  • Conventional white LEDs use a phosphor containing rare earths on a blue chip, but the new chip emits white light on its own, with no separate phosphor or packaging step.
  • The companies say mass production will begin in the fourth quarter of this year, and because the chip needs no rare earths or packaging, manufacturing costs could fall to about half those of existing products.
  • سیول وائیوسس اور اس کی بنیادی کمپنی سیول سیمی کنڈکٹر نے ڈبلیو آئی سی او پی 3 نامی انتہائی چھوٹی ایل ای ڈی چپ تیار کی ہے جو نایاب معدنیات کے بغیر سفید روشنی دیتی ہے، اور 29 اکتوبر کو دونوں کمپنیوں کے حصص روزانہ کی اوپری قیمت کی حد تک پہنچ گئے۔ عام سفید ایل ای ڈیز میں نیلے چپ پر نایاب معدنیات والا فاسفور استعمال ہوتا ہے، لیکن نئی چپ خود سفید روشنی دیتی ہے، اس کے لیے الگ فاسفور یا پیکنگ کے مرحلے کی ضرورت نہیں۔ کمپنیوں کا کہنا ہے کہ اس سال کی چوتھی سہ ماہی میں بڑے پیمانے پر پیداوار شروع ہو گی، اور چونکہ چپ کو نایاب معدنیات یا پیکنگ کی ضرورت نہیں، اس لیے تیاری کی لاگت موجودہ مصنوعات سے تقریباً آدھی ہو سکتی ہے۔ یہ پیش رفت اہم ہے کیونکہ نایاب معدنیات کی فراہمی دنیا بھر میں الیکٹرانکس بنانے والوں کے لیے ایک اسٹریٹجک تشویش بن گئی ہے۔
  • सियोल वायोसिस और उसकी मूल कंपनी सियोल सेमीकंडक्टर ने डब्ल्यूआईसीओपी3 नाम की अति-छोटी एलईडी चिप विकसित की है जो दुर्लभ खनिजों के बिना सफ़ेद प्रकाश देती है, और 29 अक्टूबर को दोनों कंपनियों के शेयर दैनिक ऊपरी मूल्य सीमा तक पहुँच गए। पारंपरिक सफ़ेद एलईडी में नीली चिप पर दुर्लभ खनिजों वाला फ़ॉस्फ़र इस्तेमाल होता है, लेकिन नई चिप स्वयं सफ़ेद प्रकाश देती है, इसके लिए अलग फ़ॉस्फ़र या पैकेजिंग चरण की ज़रूरत नहीं। कंपनियों का कहना है कि इस साल की चौथी तिमाही में बड़े पैमाने पर उत्पादन शुरू होगा, और चूँकि चिप को दुर्लभ खनिजों या पैकेजिंग की ज़रूरत नहीं, इसलिए निर्माण लागत मौजूदा उत्पादों से लगभग आधी हो सकती है। यह सफलता इसलिए महत्वपूर्ण है क्योंकि दुर्लभ खनिजों की आपूर्ति दुनिया भर में इलेक्ट्रॉनिक्स निर्माताओं के लिए एक रणनीतिक चिंता बन गई है।

Seoul Viosys and its parent Seoul Semiconductor have developed an ultra-small LED chip called WICOP3 that produces white light without rare earths, and shares in both companies hit their daily upper price limit on October 29. Conventional white LEDs use a phosphor containing rare earths on a blue chip, but the new chip emits white light on its own, with no separate phosphor or packaging step. The companies say mass production will begin in the fourth quarter of this year, and because the chip needs no rare earths or packaging, manufacturing costs could fall to about half those of existing products. The breakthrough matters because rare-earth supplies have become a strategic concern for electronics makers worldwide.
