摘要： A touch sensor includes a first substrate, a second substrate, an inducing electrode and an inducing switch. The second substrate is disposed opposite the first substrate. The inducing electrode is disposed on the first substrate. The inducing switch disposed on the second substrate includes a first switch electrode, a second switch electrode and an active layer, which is disposed between and contacts with the first switch electrode and the second switch electrode. The active layer and the inducing electrode face each other and are separated by a distance. When the first substrate or the second substrate is pressed so that the distance between the inducing electrode and the active layer is changed, the driven inducing electrode induces a channel, corresponding to a change of the distance, on the active layer to electrically connect the first switch electrode to the second switch electrode.

摘要： A touch panel includes a first substrate, a sensing electrode structure, a second substrate, a soft spacer layer and a shielding layer. The first substrate and the second substrate are parallel to each other, and the soft spacer layer is interposed between the first substrate and the second substrate for maintaining a gap between the first substrate and the second substrate. The sensing electrode structure is disposed on the first substrate for producing a first capacitance between the sensing electrode structure and an exterior object. The shielding layer is disposed on the second substrate, electrically connected to a ground side, and used for producing a second capacitance between the shielding layer and the sensing electrode structure when the exterior object is pressed and causes the gap to vary. The quantity of variation in the first and second capacitances is used for detecting a touch-control action of the exterior object.

摘要： A pixel circuit related to an organic light-emitting diode (OLED) is provided. When signals having appropriate operation waveforms are supplied, the circuit configuration (7T1C or 5T1C) of the pixel circuit keeps the current flowing through an OLED unaffected by the impact of IR drop on a power supply voltage Vdd (or mitigates the impact of the power supply voltage Vdd on the current) and prevents the current flowing through the OLED from changing with the Vth shift of a TFT for driving the OLED. Thereby, the luminance uniformity of an OLED display adopting the pixel circuit is greatly improved.
