A resistive touch device with no visual color difference 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.

Resistive touch device without perception of color difference

A portable electronic device includes a touch control module and a processing module. The touch control module has a substrate, a transparent conductive layer, a conductive decoration pad, a decoration layer and a non-transparent conductive layer. The transparent conductive layer is disposed on the substrate. The conductive decoration pad is disposed on the transparent conductive layer. The decoration layer is disposed on the conductive decoration pad and the transparent conductive layer, and has an opening. The non-transparent conductive layer is disposed on the decoration layer and electrically connected with the transparent conductive layer via the opening. The processing module is electrically connected with the touch control module.

Portable electronic device and touch control module thereof

An electrode and an isolation layer of a touch device are the same color, so that a user of the touch device perceives a good visual effect without having to employ expensive optical adhesive and decorative films in the touch device. The front bezel design used in conventional touch devices can thus be abandoned. Further, simpler fabrication, higher yield rate, and lower cost are also achieved.
