Oncell触摸技术将触摸感应膜层集合于液晶显示面板上,相较于常规的双层技术方案,具有更轻薄化,透过率更高,制程更优的特点.本文将单层多点电容方案、复合盖板、防反射、防指纹涂层、全贴合等新技术用在了 Oncell 上.研究了在车载复杂状况下的使用,可匹配不同的液晶显示驱动技术.经过试验测试,最新开发的 Oncell触控技术,可以支持3点以上触控,支持戴手套操作,通过头部撞击试验,其表面反射率低于3％,线性度为±1．5 mm,最新开发的 Oncell触控技术关键技术问题得到了解决,经过测试,可以满足车载产品苛刻的要求.今后Oncell触摸技术也必将会成为车载触控领域重要的技术方案.
Oncell touch panel technology is a new technology of touch panel which touch sensor is inte-grated on the surface of LCD.Compared with outcell touch panel,oncell touch panel is thinner,lighter and easier to produce.New technology, such as single layer multi-touch capacitor touch panel, PMMA+PC cover,AR,AF film and optical bonding etc.are used in Oncell touch panel.Oncell touch panel can match different LCD driving method.Oncell touch panel can run regularly in rugged environ-ment such as complex electromagnetic environment,strong sunlight,high and low temperature. Finally,the new technology of Oncell touch panel can support up than 3 point touch,glove touch and head impacted test.The surface reflectance is lower than 3%,and linearity is ± 1 .5 mm.The Oncell touch panel solved the key technical problems and can pass the automotive test.Thus Oncell touch technology will be the most important technology of automotive.
