Problems solved by technology

However, if the touch electrodes used for sensing touch signals in the capacitive touch panel are made of metal or a non-light-transmitting conductive material with better conductivity, the touch electrodes must be arranged along the periphery of the pixel to avoid Reduce the reduction of the aperture ratio. Therefore, the area of ​​the touch electrode is limited, and the shape is also limited to a grid shape, resulting in a reduction in the sensing area of ​​the touch electrode, thereby reducing the impact of the touch electrode on the touch of a finger or a stylus. Sensitivity of time, seriously affect the touch effect

Abstract

The invention provides a touch panel comprising a substrate, a pattern touch control layer, a pattern insulation layer, and a pattern conductive layer. The pattern touch control layer is disposed on the substrate, and the pattern touch control layer comprises a plurality of touch control electrodes, which are provided with various openings. The pattern insulation layer is disposed on the touch control electrodes. The pattern conductive layer is disposed on the substrate, and comprises at least a conductive electrode, which is electrically connected with the touch control electrode. The part of the conductive electrode is used to substantially cover the opening of the electrically connected touch control electrode.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a touch panel capable of increasing the sensing area of ​​the touch electrodes. Background technique [0002] In today's market of various consumer electronic products, portable electronic products such as smart phones (smart phones), digital cameras (digital cameras), satellite navigation systems (GPS) and tablet PCs (tablet PCs) have been widely used A touch panel replaces traditional input devices such as a keyboard and a mouse as a human-machine data communication interface to reduce the size of electronic products. [0003] According to different touch mechanisms, touch panels mainly include capacitive touch panels, resistive touch panels, and optical touch panels, among which capacitive touch panels are the mainstream products of current touch panels. However, if the touch electrodes used for sensing touch signals in the capacitive touch panel are made of metal or a non-light-trans...
