有機發光二極體(Organic Light Emitting Diode )因其具有自發光性(不需背光模組)、亮度高、視角很廣、電壓需求低、效率高、反應快、重量輕、厚度薄以及其構造簡單等優點，而被視為21世紀最具發展性的產品之一。未來若能突破生產成本高及壽命問題，OLED將可取代LCD，成為新一代熱門平面顯示器。
因OLED具有前瞻性，目前很多研究皆針對OLED的製程設計，材料分析，及檢測題材作探討。而在檢測方面，則有暗點、刮傷、亮度不均、色純度不一等問題，其中亮度不均問題多以材料、製程方面做改善，但其花費的時間跟人力都很多，所以本研究提出一自動化亮度檢測及補償機制，以達到面板亮度均勻性，提昇產品的品質。
本研究乃針對有機發光二極體面板作研究，透過彩度計CS200檢測面板各區的RGB平均亮度值及色度座標，首先先校正RGB三色的灰階值使面板顯現的白光不失真，再透過線性運算方式將所有區域應補償的值建立一ACLUT，嵌入驅動電路裡，使面板在輸出顯示之前先透過補償程式再將補償後資料傳送至顯示暫存器，讓面板的發光亮度均勻性得到較好的結果。
本研究以96×64之面板進行實驗，以電流驅動方式點亮OLED面板，而白光經由校正灰階值及補償亮度值後，其CIE色度座標由[0.28 , 0.34]偏綠的顏色校正為[0.31 , 0.32]較接近存白光顏色的區域，而補償後亮度均勻性也由原本72.53%提升到91.27%，其均勻性提高了18.74%，印證本方法能有效改善因面板製程而造成色彩失真及亮度不均的影響。

OLED (Organic Light Emitting Diodes) is regarded as one of the most competitive products in the 21st century, because they are self-emission (don’t need backlight ), high brightness, wide view angle , low driving-voltage , high efficiency, fast response , light weight , slim profile and simple structures etc. If the problems of high production cost and short lifetime can be overcome in the future, OLED maybe replaces LCD to become a popular Flat Panel Display in the new generation.
Because of the prospect of OLED, a lot of research discuss on the design of the manufacture process, Material analysis, and the study of inspection. The inspection of OLED shows some shortages such as dark point, surface scratch, non-uniform luminance, lack of color uniformity etc. Among them, the issue of non-uniformity is improved by changing material or manufacture process. But those spend too much time and manpower. Thus, this research proposes an automation system of luminance inspection and compensation that can raise the uniformity of display luminance and improve the quality of the products.
This study focuses on the uniformity compensation of color Organic Light Emitting Diode panels. It measured the average luminance and the C.I.E. chromaticity coordinates of RGB of each area panels by the chroma meter. Firstly, it should adjust the gray levels of RGB to obtain the correct white balance. Then, the system computes the compensation value of all area in the panel to Area Compensation Look-up table(ACLUT) and inset to driving circuit through the linear interpolation equation. Before appearing all pixel signals on the panel by ACLUT, the original pixel signal should be compensated to get the luminance uniformity.
This research carries on the experiment with the OLED panel of 96* 64 driven by the electric current. Before compensation, the C.I.E. chromaticity coordinates of white light is [0.28, 0.34] that is towards the green light, and the luminance uniformity of white lighting is 72.04 %. After the compensation, the C.I.E. chromaticity coordinates of white light is [0.31, 0.32] that is towards pure white light, and the luminance uniformity of white lighting is 93.76 %. The luminance uniformity increases 21.74 %. So it proves that this method can effectively improve the non-uniform luminance which may be caused by manufacture process.
