SGDR-EA1400N 三星電子的Mini LED驅動芯片與LED電流驅動芯片，S6LP441。S6LDMB1為控制芯片,S6LP441的運行受其控制。
電視屏幕中封裝的LED數量的增加，需要使用更多的半導體集成電路，不僅使內部系統變得更加復雜，也極大增加了建立精細化控制的難度。對此，工程師Seongjong Yoo解釋說：“為了解決這個問題，我們借鑒了LCD電視顯示屏常用的矩陣驅動方案。通過采用矩陣驅動，我們成功研發出了更準確、更高效的芯片解決方案，這使我們能夠在設定區域內，對更密集的LED實現更精細的控制。”
三星Mini LED驅動芯片的工作原理
這項全新芯片系統解決方案的創新之處，在于實現了LED電流驅動芯片（S6LP441）與控制器芯片（S6LDMB1）的分離。S6LP441是一款微型LED電流驅動器，附著在Mini LED的附近，以便實現對它們的精準控制。與當前業內采用的多路復用方法相比，三星電子開發的這一新系統，能夠更有效地利用LED的發光周期。不僅如此，通過限度地減少布線量，這項新系統還能有效擴大調光區，并提高集成電路自身的能源效率。
工程師Seongjong Yoo在回顧該技術的研發歷程時說：“現有的多路復用方法只能按規定間隔順序使LED發亮，很難實現對時序的精準控制。我們團隊分析了每個LED操作方法的優勢，致力于實現更高效的發光效果，同時減少所需的布線量。”

三星Mini LED驅動芯片帶來的行業啟示
“對電視來說，調光技術非常重要。例如，在電視屏幕上呈現夜空等場景時，調光技術通過強化天空的暗度、增加月亮和星星的亮度，從而實現更清晰的場景呈現。”工程師Sang-gu Kang說，“憑借其本地調節光量的特性，該技術能夠通過實現高對比度來提高電視HDR（高動態范圍）的性能，從而在發光調節和強度控制等方面達到行業更高水平。”
隨著技術的發展，用戶對高清電視的期望和需求正在不斷提高。Kyungtaek Kim在談到該行業的未來前景時指出：“在未來，電視搭載的LED數量將會更多，LED驅動芯片將變得更微小、更高效。隨著應用范圍的持續擴大，下一代LED驅動芯片解決方案將有望廣泛應用于其他產品領域。”
隨著Mini LED驅動芯片在三星電視產品中的使用和推廣，消費者將很快有機會親自體驗這項新技術。
