Abstract

A touch panel comprises a first transparent conductive substrate, a second transparent conductive substrate and a spacer layer. The first transparent conductive substrate with a bottom thereof has a plurality of first transparent conductive electrodes, and a first voltage difference in a first direction. The second transparent conductive substrate with a top thereof has a plurality of second transparent conductive electrodes, and a second voltage difference in a second direction. The first direction is perpendicular to the second direction. The spacer layer is formed between the first and second transparent conductive substrates, which is used for isolating the first transparent conductive electrode and the second transparent conductive electrode. The first transparent conductive electrodes are configured to comply with certain specifications included a differential value of Euclidean distance, a yellow / blue differential value in a color space, or dimensions between each adjacent electrodes.

Description

technical field [0001] The present invention relates to a touch device, in particular to a resistive touch device without visual color difference. Background technique [0002] With the advancement of technology, electronic devices with touch panels such as personal digital assistants (PDAs), mobile phones, and tablet notebook computers are becoming more and more popular. Touch panels on the market can be divided into several categories according to their design principles. , and the most representative touch panel is a resistive touch panel. [0003] The principle of the resistive touch panel is to use a finger or any object to press the surface of the touch panel, so that the upper and lower conductive layers inside the touch panel are in contact, generating a voltage change, and then detecting the touched position on the surface of the touch panel. Such as figure 1 As shown, the touch panel includes a first substrate 10, a spacer layer 12 and a second substrate 14. The ...
