页面更新时间:2015-05-20 11:24 来源:未知 作者:admin 点击:

济南冲孔字目前使用的为民品级别的器件,使用寿命不超过8年。作为它的功能是观看,当它亮着只有晚上才能看清楚时是无法说明它是合格的、具备使用价值的。

Ji'nan punching word currently used for civilian device level, the service life is not more than 8 years. As it is a watch and when they are lit only at night to see is unable to show that it is qualified, have use value.

济南冲孔字出具的技术资料表明发光体的寿命为理想状态下10万小时。理想状态指在实验室中恒压恒流状态下LED发光体从发光到完全不发光的时间,10万小时折合11年。

The technical data issued by the Ji'nan word that punching a luminous body for 100000 hours under the ideal state of life. Refers to in the laboratory in constant voltage and constant current LED luminous body from light to a completely non luminous time ideal state, 10 million hours equivalent to 11 years.

一、 遵守国标

One, comply with GB

济南冲孔字通用规范为1995年的部颁标准。至今还有许多公司号称符合国家标准,在科技发展的8年以后再看当时的标准,已经不是标准了。比方说失控点,国标为万分之三,以φ3.75室内双基色显示屏为例。一般做640x480标准分辨率的显示屏为7平米,每平米为43264点,按国标可以有90个失控点。这样的显示屏在今天谁还买单。

General specification for punching Ji'nan 1995 ministerial standard word. Since there are many companies claim to conform to the national standard, after 8 years of development of science and technology look when the standard, is not standard. For example a point out of control, the national standard for the 3/10000, with Phi 3.75 indoor dual color display case. General 640x480 standard resolution display is 7 square meters, per square meter of 43264 points, according to the national standard can have 90 control points. Such a display today who also pay.

二、 软件全免费

Two, the software free

济南冲孔字行业普遍存在着中国企业的通病——只生产不研发。目前只有少数企业拥有正版的软件。现在使用盗版是违法的。

Ji'nan punching word industry generally has Chinese enterprises failing, not only the production of R & D. Only a few of the enterprises have genuine software. It is illegal to use piracy now..

三、 价格低廉

Three, low prices

要看性能价格比而不是单纯看价格。

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

四、 灰度等级

Four gray level

作为双基色和全彩色显示屏的灰度是一个重要指标。目前市场上充斥着许多1 6级和64级灰度的显示屏冒充256级灰度。其控制成本只有256级灰度的控制的1/5。最简单的方法是播放一个比较激烈的运动场面的VCD查看led显示屏上是否能够看清楚。

As the gray double color and full color display is one of the important indexes. At present, the market is flooded with many 16 and 64 gray screen posing 256 gray. 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 view LED display is able to see clearly.

五、 要买就要最好的

Five, to buy the best

一切购买力来源于需要,满足需要并有一定的超前。盲目的追求将浪费很多资金购买了自己不需要的功能。

All purchasing power sources to meet the needs, and have certain in advance. Blind pursuit will waste a lot of money to buy their unwanted features.
