Abstract:	Micro-LED技術是一種新興的顯示技術，具有許多引人注目的優勢。首先，Micro-LED顯示器擁有極高的亮度，這使得它在室內和室外環境中都能提供出色的視覺效果非常適合用於商業廣告牌和戶外大屏幕。其次，Micro-LED顯示器具有極低的功耗。相比傳統的液晶顯示器和有機發光二極管（OLED）顯示器，Micro-LED顯示器在相同亮度水平下消耗的能量更少。這種低功耗有助於延長顯示器的使用壽命，同時降低能源消耗，符合環保和節能的要求。此外，Micro-LED顯示器在色彩性能方面表現出眾。它能夠呈現廣色域，具有更高的色彩飽和度和更準確的色彩再現能力。這意味著Micro-LED顯示器可以更好地呈現真實世界中的色彩，使影像更加生動逼真。對於需要高色彩準確性的應用，如專業圖形設計、影像編輯和醫學影像顯示，Micro-LED顯示器提供了一個理想的解決方案。然而，要驅動Micro-LED顯示器並實現這些優勢，需要複雜的控制算法和高速數據處理。這就帶來了一些挑戰，如如何實現實時控制、確保色彩準確性和保持系統的穩定性。為了應對這些挑戰，本研究開發了一個基於FPGA的實時控制系統，專為68英寸4K/60Hz的Micro-LED顯示器而設計。該控制系統具有高性能和精確的控制能力，能夠實現精確的色彩準確度，並支持10位色深以提升色彩再現效果，並且為了戶外大型顯示屏的考量，實現收發端長距離的傳輸。為了確保整個顯示器上的色彩一致性，系統實現了色彩校準技術，使得每個Micro-LED元素都能呈現一致的色彩。 ;Micro-LED technology is an emerging display technology that offers numerous remarkable advantages. Firstly, Micro-LED displays possess incredibly high brightness, making them suitable for both indoor and outdoor environments and ideal for commercial billboards and outdoor large screens. Secondly, Micro-LED displays have extremely low power consumption compared to traditional LCD displays and organic light-emitting diode (OLED) displays, resulting in extended display lifespan and reduced energy consumption, aligning with environmental sustainability and energy-saving requirements. Additionally, Micro-LED displays excel in color performance. They can achieve a wide color gamut, higher color saturation, and more accurate color reproduction, allowing for vivid and lifelike image rendering. For applications demanding high color accuracy, such as professional graphic design, image editing, and medical image displays, Micro-LED displays offer an ideal solution. However, driving Micro-LED displays and harnessing these advantages require complex control algorithms and high-speed data processing. This poses challenges in achieving real-time control, ensuring color accuracy, and maintaining system stability. To address these challenges, this study presents the development of a real-time FPGA-based control system specifically designed for a 68-inch 4K/60Hz Micro-LED display. The proposed control system exhibits high performance and precise control capabilities, enabling accurate color accuracy and supporting 10-bit color depth for enhanced color reproduction. Additionally, the system incorporates long-distance transmission capabilities for outdoor large screens. To ensure color consistency across the entire display, the system implements color calibration techniques, ensuring uniform color presentation for each Micro-LED element.
