  1. The control system included the following units : video decode unit, data format conversion unit, fpga controller, cache unit and d / a monitor. the above self - design control unit plus row and column power supply units make the whole fed driving system, thus drove the 25 inch sample and realized color video display. the 25 inch vga sample thus fabricated could display video images, and obtained its brightness 400cd / m2, contrast ratio 1000 : 1, 256 circuit gray scale

    本文介紹了fed驅動系統的工作原理，重點論述了基於fpga的vga級彩色fed新型驅動控制系統的研製，這種新型fed驅動控制系統主要包括視頻解碼電路、數據格式轉換電路、 fpga控制電路、數據緩存電路和d / a監控電路，配合后級列灰度調制單元和行掃描單元，組成完整的fed驅動系統，可以驅動25英寸vga級fed顯示屏，實現彩色視頻顯示，樣機亮度達400cd / m2 、對比度為1000 : 1 ，灰度等級為256級。
  2. The 1mhz fixed frequency switching allows for tiny external components and the regulation scheme is optimized to ensure low emi and low input ripple. an external resistor sets the full - scale led current, while two digital inputs control on / off and select amongst three levels of brightness. the circuit operates in 1x mode until just above dropout

    工作在1mhz固定頻率，採用線性調制模式使輸入紋波大大減小;利用一個外部電阻可以設置滿量程led電流;外接兩個數字信號控制晶元開關並選擇led三級亮度中的一級;具有過溫、過壓/欠壓等保護功能，工作溫度范圍為- 40 + 85 。
  3. Deferring to historical custom, astronomers, measure the apparent brightness of stars through the magnitude scale, a very confusing way.

    按照歷史習慣，天文學家用星等標這種容易使人混淆的方法來度量恆星的視亮度。
  4. In order to satisfy the railroad, electrical industry, public security, army, such industry, public security, army, such industry and mining business unit ' s big area high brightness illumination need on large - scale construction work, accient repairs, rush to deal with an emergency and rescue isaster and so on, our company developes the cqy6800 the omniberaing large - mobile lighting vehicle, it can may work normally under kinds of adverse circumstance and climatic conditions

    本公司為了滿足部隊、鐵路、電力、公安等企事業單位的大型施工作業、搶險救災等大范圍高亮度照明需要，特研製開發生產了cqy6800全方位大型移動照明車，可在各種惡劣務件下工正常工作。
  5. Finally, the anti - jamming system is discussed. through simulation analysis and experiment on signal integrity, the method of improving stability of the circuit is presented. circuit testing proves that the “ sub - row ” gray - scale modulating method is suitable for our printable fed with low work. the designed circuit has been applied to our fed sample which can display vga format video with 256 gray - scale and brightness of 400 cd / m2

    實際電路測試證明，子行灰度調制的方法適用於印刷型低逸出功fed顯示屏，所設計的灰度調制驅動電路已成功應用於25英寸彩色fed樣機中，可顯示vga格式視頻圖像，灰度等級為256級，顯示亮度達400cd / m2 。
  6. To tell others how bright a star is. it is a log scale in intensity. thus, magnitude and intensity both are scales for brightness of a star

    來標示恆星的亮度，這是恆星光度的對數log ，所以，等數及光度皆可用來標示恆星的亮度。
  7. The algorithm combines the concept of binary feature coding and mapping with the concept of brightness comparisoa because the feature is encoded under a relatively small scale, the algorithm needs oriented template and local feature distinguishment

    由於特徵編碼映射是在一個較小的尺度下進行的，因此演算法還需利用方向模板以及角特徵確認過程對初始定位結果進地進一步擴展尺度的特徵區分。
  8. The numbers are part of a grayscale system in which brightness is measured in a range of values. one scale ranges from 0 to 15 ， and another from 0 to 255

    翻譯：數字是灰度系統的一部分，在灰度系統中，一個范圍內的亮度用一些數字被測量表示。一個刻度范圍是0到15 ，另一個是0到225
  9. The researchers then searched for pairs of photographs that were similar in all respects ? in brightness and contrast, for example ? but at opposite ends of the attractiveness scale

    研究者隨后找出幾對個方面很像的照片? ?比如亮度和對比度? ?但是它們有不同的吸引力數值。
