Abstract

The invention discloses a capacitive touch panel. The touch panel comprises a transparent substrate of which the surface is provided with a plurality of first and second inductive electrode groups, wherein a plurality of first inductive electrodes are connected in series through a plurality of first leads so as to form each first inductive electrode group; each second inductive electrode group is provided with a plurality of second inductive electrodes; an insulated netlike color compensating layer is arranged between the first and second inductive electrodes; and the plurality of second leads cover the partial surface of the color compensating layer to serially connect the second inductive electrodes. Therefore, a shadow formed by the profile of the inductive electrode can be reduced effectively and the effect description of visual quality is increased.

Description

technical field [0001] The invention is applied to the technical field of touch panels, in particular to a capacitive touch panel that can effectively reduce afterimages between electrodes. Background technique [0002] Generally known capacitive touch panels, due to the difference in refractive index of different materials, and the design of different electrode patterns, will produce shadows on the contours of each electrode, such shadows are called afterimages. The afterimage will affect the visual effect, especially when it is installed on the surface of the display, the related afterimage will cause noise on the image, resulting in poor picture quality. Contents of the invention [0003] The main purpose of the present invention is to provide a capacitive touch panel, which can effectively reduce the afterimage formed by the outline of the sensing electrodes by setting the color compensation layer to match the sensing electrodes, so as to increase the effect of visual ...
