Capacitance type touch control panel and manufacturing method thereof

Abstract

A capacitor type touch control panel sequentially comprises a first transparent insulating layer which comprises an X axial core mark, a second transparent insulating layer, a second transparent conductive material layer which comprises a Y axial core mark, and a third transparent insulating layer. The X axial core mark is provided with a first core mark contact. The Y axial core mark is provided with a second core mark contact. The invention is characterized in that a first transparent oriented layer is provided between the second transparent insulating layer and the first transparent conductive material layer comprising the X axial core mark. A second transparent oriented layer is provided between the second transparent insulating layer and the second transparent conductive material layer comprising the Y axial core mark. The second transparent insulating layer is composed of liquid crystal. The invention also provides a method for preparing the capacitor type touch control panel. The invention can realize a two-dimensional locating function, and furthermore the second transparent insulating layer is equivalent to a wave plate. The linearly-polarized light which emits to the touch control panel can be leaded to become right circular polarized light or ellipse polarized light. The phenomenon of blind zone existing in some specific application occasions can be overcome.

Description

technical field

[0001] The invention relates to an input device for human-machine interaction, in particular to a capacitive touch panel capable of realizing two-dimensional positioning and a manufacturing method thereof. Background technique

[0002] At present, the touch panel is combined with a liquid crystal display as an input device, and is widely used in various electronic products, such as vehicle and ship products, public inquiry systems, household appliances, and various portable information terminal electronic products (such as high-end PDA (Personal Digital Assistant, personal digital assistant), smart phone, digital camera, game console, etc.).

[0003] The light emitted by the liquid crystal display is usually linearly polarized light. Since the existing touch panel usually does not change the polarization state of the light, the light passing through the touch panel is still linearly polarized light, which has some problems in practical applications.
