| dc.description.abstract | 本論文旨在探討一套完整的微發光二極體(Micro-LED)驅動電路與系統設計開發流程，涵蓋實驗初期採用TFT玻璃基板之設計，後續開發以矽基(silicon-based) CMOS類比驅動晶片搭配FPGA數位電路為主軸，透過PCB設計與wire bonding技術整合Micro-LED晶片，完成被動式驅動系統開發。最終成功驅動單顆尺寸為 50 µm 的Micro-LED陣列。
初期實驗以TFT玻璃基板進行設計，完成包含GOA(Gate on Array)電路與主動式2T1C像素架構之面板，並搭配DRC command file開發，完成電路設計與驗證。隨後類比電路轉向以UMC 0.18 µm製程矽基CMOS晶片作為Data Driver，設計輸出可對應亮度之電壓信號來驅動Micro-LED，其中電路包含數位類比轉換器、運算放大器、類比電壓緩衝器等；數位電路則整合TCON與Scan Driver模組，產生驅動系統所需控制時序訊號，包含邊緣偵測器、去雜訊電路與有限狀態機(FSM)等控制單元。在本論文整合兩種主流的Micro-LED調光方案，使用PWM與PAM混合調光被動式電壓驅動技術，實現更新率為60 Hz之5x5 Micro-LED陣列驅動系統，並且透過外部補償解決Micro-LED顯示畫面均勻度之問題。 本論文也針對Full custom設計流程、FPGA設計流程與PCB設計流程進行介紹，包含類比晶片Layout優化過程、數位電路設計時的考量和PCB規劃與系統整合細節。 | zh_TW |
| dc.description.abstract | This thesis presents the complete development of a Micro-LED driver circuit and system. The work begins with an early prototype based on a TFT glass substrate, then transitions to a silicon-based CMOS analog driver IC integrated with FPGA digital control. Using PCB design and wire bonding, a passive driving system was successfully implemented, enabling operation of a Micro-LED array consisting of 50 µm Micro-LED chips.
The initial design includes a GOA (Gate on Array) and 2T1C pixel structure, with circuit verification completed using a self-developed DRC command flow. The analog driver, fabricated using UMC 0.18 µm CMOS technology, outputs brightness-controllable voltage signals through DACs, OPAs, and analog buffers. The FPGA-based digital subsystem integrates TCON and Scan Driver modules, including edge detection, debounce circuits, and FSMs to generate necessary timing signals. This thesis combines two widely used Micro-LED dimming techniques, adopting a hybrid PWM and PAM passive voltage-driving approach. A 5×5 Micro-LED array operating at 60 Hz was successfully implemented, with external compensation applied to improve display uniformity. The thesis also details the full-custom analog IC design process, FPGA control logic, and PCB integration, including layout optimization and system-level design considerations. | en |
