元器件交易网讯 3月13日消息，据外媒报道，韩国专利代理于3月13日称，三星电子提交了一份解锁智能手机新方法的专利。
三星称方法是捕捉绘制在屏幕上线的交点，相比三星目前连接指定的圆圈的系统，这个方法允许用户设定一个更大范围的代码选择。
三星在专利申请中表示，“该功能允许用户以一种更方便的方式解锁(智能手机)。图案并不局限于某个区域、点或形状，解锁屏幕比以前更自由了。”
上月LG电子展示了其Knock Code，是在LG G2上的Knock On基础上进行改进升级，该技术允许用户轻敲屏幕进行解锁。
索尼和诺基亚早前也推出过敲屏的功能的设备。

South Korea"s tech giant Samsung Electronics Co. filed a patent for a new way of unlocking smartphones by freely drawing lines on screens, the country"s patent agency said Thursday.
The world"s top smartphone maker said the new method is based on catching intersecting points of lines drawn on the screens, allowing users to set a wider choice of codes compared to Samsung"s current system of connecting designated circles.
"The feature allows users to unlock (smartphones) in a more convenient way," Samsung said in its patent filing. "As patterns are not restricted to an area, spot or shape, users can unlock screens more freely than before."
The patent was filed by Samsung in September 2012 and was disclosed by the state-run Korean Intellectual Property Office on Thursday.
Global tech firms have been sharpening unlocking technology as their newest features on smartphones as security has become a major concern for users.
Last month, LG Electronics Inc., Samsung"s smaller local rival, showcased its "Knock Code," an updated smartphone feature of its previous "KnockOn," which allows users to unlock devices by tapping the screen several times. The previous version only allowed turning on and off of the devices.
Sony Corp. and Nokia Corp. earlier also rolled out devices with tapping-style features.
Samsung"s latest Galaxy S5 smartphone, slated to be released in April, adopted fingerprint screening to boost its security, which is also anticipated to be applied to mobile transactions.
