A touch panel is provided in the present disclosure, including: a substrate, a conductive trace structure, and a light-shielding structure. The substrate includes a visible area and a peripheral area, and the visible area is surrounded by the peripheral area. A conductive trace structure is disposed on the visible area. The light-shielding structure includes a first material layer and a second material layer, in which the optical density of the light-shielding structure is lower than 4, the first material layer is disposed on the peripheral area, and the second material layer is disposed on the first material layer. A method of manufacturing a touch panel is provided in some embodiments of the present disclosure for the effects of saving cost and improving wire drift.

Touch panel, electronic device and manufacture method thereof

A touch device has multiple charging traces distributed under the touch operation area. When the object hovers over or contacts the touch operation area, the control unit of the touch device obtains the corresponding position of the object through the sensing signal of the electrode units. The control unit in turn connect the charging traces adjacent to the corresponding position of the object to form at least one charging loop. In the process of the touch operation on the touch device, the object can be charged at the same time, and the convenience of use can be improved.

Touch device with charging function and charging control method thereof

A touch system has a touch device and an input device. The touch system executes a first mode and a second mode at different times. In the first mode, the touch device transmits a modulation signal to drive the touch electrodes and to be used as an uplink signal. The input device receives the modulation signal. In the second mode, the touch device receives the downlink signal from the input device. Thus, the touch device does not have to transmit the driving signal and the uplink signal at different times. Then the time is saved for the rest work periods so that every work periods get longer length of time.

Touch system, its touch device and input device, and its signal transmission method

A touch system includes a touch device and an input device. The uplink signal transmitted by the touch device includes a timestamp. The input device transmits a downlink signal through the electrode unit and transmits a side information through a wireless communication unit. The inclusion of the corresponding timestamp in the side information ensures that the side information is combined with the corresponding downlink signal to correctly present the user's operation.

Touch system, input device for the same and signal transmission method for the same

A design of cognitive radio (CR) signal structure which based on the spectral correlation can be used for active sensing. In this signal structure, the known pilots used for the primary users (PUs) are duplicated and reallocated in the CR transmission signal properly. With this CR signal structure, the received signal of spectrum sensors will become correlated on the subcarriers when PU reoccupation occurs while the CR transmission is active, and thus PU activities can easily be detected by computing the spectral correlation function. As compare with the traditional cyclostationary feature detection scheme, this method can enhance the active sensing performance while remaining the service quality of the CR system, achieving better detection performance in the same detection time, reducing sensing time (about 1/10 of the traditional sensing time), and still reaching the satisfactory outcome even in the circumstances of low SNR and SINR.
