luminance brightness 中文意思是什麼
-
The brightness or luminance of an object is defined as the luminous flux emitted per unit area of the object into unit solid angle.
物體的亮度或發光率定義為物體面積發射到單位立體角內的光通量。 -
In this thesis, the image enhancement was also studied, such as dlti 、 dcti ( digital luminance 、 color transient improvement ), peaking ( luminance peaking ), ble ( black - level enhancement ), brightness 、 hue 、 contrast and saturation adjustment, and then the hardware circuit was designed
研究了dlti （數字亮度瞬態增強） ， dcti （數字色度瞬態增強） ， peaking （亮度峰化） ， ble （黑電平延伸） ，亮度、色調、對比度和飽和度調整等圖像增強技術，並完成了圖像增強電路的設計。 -
Compared with green light - emitting device, blue oled has many problems such as brightness, efficiency, stability, and color saturation, in this study we investgaited the blue oleds systemically : 1 ) double heterosturcture oled was charaterized. due to the introducing of electron transport layer alq3 and hole - blocking layer balq3, the energy matching was more reasonable and the carrier injecting was more effective in the double - layer device. the maximum efficiency and luminance of this device attained to 1. 90 lm / w and 10, 000 cd / m2, respectively
其次，由於一直以來藍光oled器件的研究處于相對落後的狀態，其發光亮度、效率、穩定性和色純度都無法綠光器件相比，所以本論文在以下幾個方面對藍光器件的性能進行了系統的研究: 1 ）研究了雙異質型藍光oled器件，由於本研究引入了空穴阻擋層，使得載流子的復合和激子的擴散被限定在發光層內，器件的發光效率達到了1 . 90lm / w ，最大亮度達到了10000cd / m2 ，比傳統結構器件的效率和亮度提高了約一個數量級; 2 ）制備了結構為ito / npb / balq3 / alq3 / mg : ag的oled器件，研究發現，當改變各有機層厚度時，器件的電致發光光譜發生了從綠光到藍光的移動。
