1引言有要發光二極管(OLED)具有低驅動電壓、寬溫工作、主動發光、響應速度快和視角寬等優點],其作為全彩顯示器件,與LCD相比,具有更簡單的工藝和更低的成本。近年,單色和局域色的OLED顯示屏已有較多報道~1,并推出了全彩OLED顯示屏~9]。本文研制了尺寸為1.9、分辨率為128(×3)×160的全彩OLED屏。在目前報道的同等或以下尺寸的采用無源矩陣(PM)驅動的全彩OLED屏中,該屏的分辨率處于較高水平。2全彩OLED屏2.1全彩技術的實現圖1是5種實現全彩OLED顯示屏技術的示意圖。本文采用(a)所示的平面結構式,每個全彩像素包括紅、綠和藍3個子像素,利用空間混色實現彩色。這種技術的難點是在制作全彩OLED時,需要將紅、綠和藍OLED的發光層(EML)材料分隔開01。屏的最高分辨率不僅受限于機械掩模制作的公差,還受限于在器件制作工藝過程中機械掩模與ITO基板玻璃的對準誤差。2.2P-OLED屏的驅動技術OLFD屬于電流型器件,其發光亮度與驅動電流成正比,故OLED均采用恒流源驅動。由于OLED自身較高的寄生電容(20~30pF/Pixel)和ITO電極引線的電阻(幾~幾109/口形成的電壓降,對恒流源的性能提出了較高的要求,例如可提供高達~30V的電壓。為了實現多灰度顯示,電流必須可程控。lare公司為了精確控制每個OLED子像素的發光亮度,提出了預充電方案]。根據有無開關和驅動薄膜晶體管的存在,可將矩陣式OLED的驅動可分為P10l和有源矩陣AM112種。PM驅動的顯示器件由于制作工藝比AM要簡單得多,且成本低廉,故在小尺寸的顯示器件上得到了廣泛應用。PM驅動電路如圖2所示。

文將簡要地介紹基于Lattice FPGA(XO2/XO3/ECP3/ECP5/CrossLink)器件的,MIPI CSI/DSI調試心得。如有不足,請指正。第一步、確認硬件設計、接口連接1.1、可以使用示波器測量相關器件的MIPI輸出信號(可分別在靠近輸出端和靠近接收器件接收端測量,進而分析信號傳輸問題),來確認信號連接是否正常;1.2、如信號質量較差(衰減嚴重、反射現象等等),請先檢查器件焊接是否牢靠,傳輸線上阻抗是否匹配等;1.3、如果信號一切正常,但是仍然無法找到SoT(B8),請確認差分線PN是否接反了;注:Lattice FPGA暫時未支持NP翻轉功能,不能通過軟件設置,實現類似SerDes支持的PN翻轉功能。1.4、針對非CrossLink器件,請檢查電路連接是否正確。具體請參考本文附件,以及Lattice各個器件的相關手冊;1.5、如果是MIPI N進1出的設計(N合一),建議各個輸入器件采用用一個時鐘發生器(晶振),即同源。同時FPGA MIPI Tx所需要的時鐘源,最好也與其同源。如果不同源,建議Tx的時鐘要略高于Rx的時鐘(如Pixel Clock);1.6、如果條件允許,可以通過示波器分析眼圖,以獲得更多的信號完整性信息。
