如今买部手机，很多人都要贴膜，原因是担心屏幕被划伤。可业内人士透露，如今的手机屏幕材质已较早期大为提升，许多手机屏本身比钥匙和指甲都还硬。如此一来，贴膜就成了一种画蛇添足的行为。

Now buy mobile phone，A lot of people want to patch，The reason is worried about the screen be scratched。But industry insiders said，Today's mobile phone screen material is upgraded substantially early，Many cell phone screen itself than keys and nails were also hard。so，Patch to become a kind of the behavior of the gild the lily。

　　“如今的手机屏越来越硬，别说指甲和钥匙，有的屏就是用刀都不一定能留下划痕。”360安全卫士公司相关负责人昨天告诉重庆晚报记者，他们公司跟海尔之前推出的一款手机在发布会现场，就有人当众用尖刀使劲划割屏幕，结果手机无丝毫划痕。

“Today's mobile phone screen more and hard，Don't say nails and keys，Some screen is the sword is not necessarily can leave scratches。”360 security guards company responsible told reporters yesterday evening of chongqing，Their company before with haier launched a mobile phone in the conference site，They tried to cut the knife with strokes in the screen，Results no mobile phone no scratches。

　　另据了解，包括苹果iPhone以及iPad等在内的很多电子产品，厂家在设计之初就考虑到了屏幕防划伤及磨损的问题。

To understand the other，Including apple iPhone and iPad, a lot of electronic products，Manufacturers in the beginning of the design considered the screen the scratches and wear。

　　“现在的手机屏幕质量确实是越来越好，今年我们这里接到的关于手机屏幕损坏(包括划痕等)的投诉并不多。”手机质量争议技术鉴定机构———中国泰尔实验室技术鉴定中心重庆代理处的工程师王女士说。

“Now the mobile phone screen quality is really getting better and better，This year we got here about mobile phone screen damage(Including scratch etc)Complaint is not much。”Mobile phone technology appraisal organization quality dispute- China laboratory technology appraisal center chongqing tell the engineer ms. Wang said。

　　据了解，现在的手机屏材质大致有玻璃、钢化玻璃、凯夫拉涂层等几种。“凯夫拉涂层是军方用于防弹衣上的一种技术，我们的产品上已经采用了这种材质。”摩托罗拉重庆分公司林先生透露说。

According to understand，Now the mobile phone screen material to roughly glass、Toughened glass、Several coating and kevlar (r)。“Coating is used to ascertain the kevlar (r) of a kind of technology，Our products have been made with this kind of material。”MOTOROLA chongqing branch Mr. Lin revealed。

　　有业内专家指出，钢化玻璃的硬度一般是6.5，而多数金属的硬度是5.5。如果金属钥匙跟钢化玻璃摩擦的话，受伤的只能是硬度更低的金属钥匙。而人的指甲硬度，更是连3都不到。

The expert inside course of study points out，The hardness of toughened glass general is 6.5，And most metal hardness is 5.5。If metal key words with toughened glass friction，The injured can only be more low hardness metal keys。But the person's nails hardness，But even less than 3。

　　“手机膜如果没选好，反而可能会影响到手机的显示效果，”重庆摩托罗位公司林先生表示。

“Mobile phone if it didn't choose good film，It may affect the mobile phone display effect，”The chongqing TuoLuo a company Mr. Lin said。

　　之所以说手机贴了劣质膜后可能在一定程度上影响屏幕的显示效果。有说法是尽管有些贴膜产品宣称其透光率可达到99%，但目前透光率最高的是光学玻璃，其透光率也仅为97%左右，而采用塑料材质制成的手机贴膜，其透光率根本不可能达到99%的数值。

The mobile phone posted inferior film may in some extent to display screen。It is though some paster product claims its transmission rate can reach 99%，But the light transmittance are highest in optical glass，The transmission rate is only 97% or so，And the plastic material made of skin cell phone，The light transmittance impossible to attain 99% of the value。

　　资深果粉刘先生说，老式触控手机使用的是电阻屏，使用时要靠手指或触笔的压力，才能有效操作，容易产生划痕和磨损，贴膜是有必要的。现在的智能电子触控产品早已进入了电容屏时代。贴膜之后相当于多了一层电阻，必然会影响感应效果，原本手指轻轻点一下，就能打开的网页，贴膜后可能要用手指重复操作多次才能达到效果。“专业的果粉，都是裸的，不用贴膜。”

Senior fruit powder Mr Liu said，Old cell phone use touch screen is resistance，When used by a finger or touch pen pressure，To be effective operation，Easy to produce the scratches and wear，Paster is necessary。Now the intelligent electronic touch products already entered the capacitance screen time。After more than a patch equivalent of resistance，Will inevitably influence on induction effect，Originally fingers check it，To open web pages，After the patch may want to use your fingers can reach many times repeated operation effect。“Professional fruit powder，Are the bare，Don't let the。”

　　而网上甚至还有未经证实的消息称，虽然目前手机屏幕本身的亮度已足够，但屏幕贴了膜后显示效果还是会受到影响，长期使用后的磨损还会进一步影响其显示效果，这无形中就会增加视觉疲劳，甚至会对视力造成损害。(记者 万里)

And online even unconfirmed sources said，Although at present the brightness of the mobile phone screen itself is enough，But the screen display posted after the film or can be affected，After long-term use of wear further affect the display effect，This virtually will increase visual fatigue，Even vision damage。(The reporter)
