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 integrated 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 environment 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.
