            濟南發光字使用的環境和方法

            頁面更新時間:2015-06-12 14:44 來源:未知 作者:admin 點擊:

            濟南發光字目前使用的為民品級別的器件,使用壽命不超過8年。作為顯示屏的功能是觀看,當顯示屏亮著只有晚上才能看清楚時是無法說明它是合格的、具備使用價值的。

            Ji'nan luminous characters currently used for civilian device level, the service life is not more than 8 years. As the function of the display is to watch, when the screen is lit only in the evening to see clearly when it is qualified, with the use of value.

            濟南發光字出具的技術資料表明LED發光體的壽命為理想狀態下10萬小時。理想狀態指在實驗室中恒壓恒流狀態下LED發光體從發光到完全不發光的時間,10萬小時折合11年。

            The technical data issued by Ji'nan light emitting word indicate that the lifetime of the LED emitter is 100000 hours in the ideal state. Ideal state means the time when the LED emitter is from the emission to the complete non luminous in the laboratory, and the time of 100000 hours is 11 years.

            一、 遵守國標

            One, comply with GB

            LED顯示屏通用規范為1995年的部頒標準。至今還有許多公司號稱符合國家標準,在科技發展的8年以后再看當時的標準,已經不是標準了。比方說失控點,國標為萬分之三,以φ3.75室內雙基色顯示屏為例。一般做640x480標準分辨率的顯示屏為7平米,每平米為43264點,按國標可以有90個失控點。這樣的顯示屏在今天誰還買單。

            General specification for LED display for the 1995 ministerial standard. So far, there are many companies known as in line with national standards, in the development of science and technology for 8 years after the standard is not the standard. For example a point out of control, the national standard for the 3/10000, with Phi 3.75 indoor dual color display case. Generally do 640x480 standard resolution display is 7 square meters, 43264 points per square meter, according to the national standard can have 90 points out of control. Such a display today who also pay.

            二、 軟件全免費

            Two, the software free

            濟南發光字 http://www.xubclan.com/ 普遍存在著中國企業的通病——只生產不研發。目前只有少數企業擁有正版的軟件?,F在使用盜版是違法的。

            Ji'nan luminous word widespread common problem of Chinese Enterprises - no research and development. Only a few of the enterprises have genuine software. It is illegal to use piracy now..

            三、 價格低廉

            Three, low prices

            要看性能價格比而不是單純看價格。

            To see the performance price rather than simply look at the price.

            四、 灰度等級

            Four gray level

            作為雙基色和全彩色顯示屏的灰度是一個重要指標。目前市場上充斥著許多1 6級和64級灰度的顯示屏冒充256級灰度。其控制成本只有256級灰度的控制的1/5。最簡單的方法是播放一個比較激烈的運動場面的VCD查看led顯示屏上是否能夠看清楚。

            As the gray double color and full color display is one of the important indexes. The current market is flooded with many 16 levels and 64 gray level of the screen posing as 256 gray level. Its control costs only 256 levels of gray level control of the 1/5. The easiest way is to play a more intense sports scene VCD to see whether the LED can see clearly.

            五、 要買就要最好的

            Five, to buy the best

            一切購買力來源于需要,滿足需要并有一定的超前。盲目的追求將浪費很多資金購買了自己不需要的功能。

            All purchasing power comes from the need, meet the need and have a certain lead. The blind pursuit will waste a lot of money to buy the functions you don't need.
