Low coupling capacitor condenser type touch control board

Abstract

The utility model provides a capacitive type touch panel with low coupling capacitance and a display unit with the capacitive type touch panel, comprising a plurality of first directional electrode strings and a plurality of second directional electrode strings. A plurality of A electrodes are arranged on the first directional electrode strings along the first direction; a plurality of B electrodes are arranged on the second directional electrode strings along the second direction. In order to reduce the lateral capacitor between the A electrode and the B electrode or the adjacent two A electrodes, the width of A electrode is reduced along the second direction from the middle part to the both sides. Furthermore, each A electrode has a circumference of A electrode form. Meanwhile, the quarter part of the circumference adjacent to the B electrode has the dissimilar first slope change rate and the second slope change rate.

Description

technical field [0001] The present invention relates to a capacitive touch panel and a display device using the capacitive touch panel; specifically, the present invention relates to a capacitive touch panel with low coupling capacitance and a display device using the capacitive touch panel display device. Background technique [0002] Display panels and flat display devices using display panels have gradually become the mainstream of various display devices. For example, thin TVs for home use, LCD monitors for personal computers and notebook computers, display screens for mobile phones and digital cameras, etc., are all products that use a large number of display panels. As product design gradually tends to be user-oriented, display panels with touch input functions have gradually become the focus of industrial development in order to consider the user's operation convenience. [0003] Taking a liquid crystal display panel as an example, as shown in FIG. 1 a , a conventio...
