一种液晶显示器用防眩膜Anti-glare film for liquid crystal display

技术领域 technical field

本实用新型涉及抗反射涂层领域，尤其涉及一种液晶显示器用防眩膜。  The utility model relates to the field of antireflection coatings, in particular to an antiglare film for liquid crystal displays. the

背景技术 Background technique

随着智能科技的发展，液晶显示器的应用领域正在逐渐增大。液晶显示器以其体积小，厚度薄，重量轻、耗能少、工作电压低且没有电磁辐射的特点，已经全面取代笨重的CRT（Cathode Ray Tube）显示器成为现在主流的显示设备。随着使用时间的不断增加，显示屏的表面很容易被指甲及一些硬件划伤，同时由于液晶显示器是一种不能够自动发光的显示器，这种显示器在外光映入其显示面的情况下，视觉辨认性会被显著损伤，产生眩光现象。因此为了增加显示屏的使用寿命，减少显示屏表面的眩光性，常常会选择在其表面覆上一层抗眩光防刮伤的保护膜。  With the development of smart technology, the application fields of liquid crystal displays are gradually increasing. With its small size, thin thickness, light weight, low energy consumption, low working voltage and no electromagnetic radiation, liquid crystal display has completely replaced the bulky CRT (Cathode Ray Tube) display and has become the mainstream display device. As the use time continues to increase, the surface of the display screen is easily scratched by nails and some hardware. At the same time, because the liquid crystal display is a display that cannot automatically emit light, this kind of display will not Visibility will be significantly impaired, resulting in glare. Therefore, in order to increase the service life of the display screen and reduce the glare on the surface of the display screen, it is often selected to cover the surface with a protective film that resists glare and scratches. the

然而，传统的保护膜一般只具有防刮伤性，其防眩光效果并不明显。而一般的有防眩光效果的保护膜，其抗刮性能也不明显，同时其表面雾度过大，表面分布不均匀，严重影响了保护膜的性能和使用。  However, traditional protective films generally only have scratch resistance, and their anti-glare effect is not obvious. However, the general protective film with anti-glare effect has no obvious scratch resistance, and at the same time, its surface haze is too large and the surface distribution is uneven, which seriously affects the performance and use of the protective film. the
