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.

A touch panel including first electrode bands, second electrode bands, and a transparent dielectric material is provided. The first electrode bands are disposed on a first substrate and extended in a first direction, wherein each of the first electrodes has a plurality of first slits in the form of enclosed configuration. The second electrode bands are disposed on a second substrate, facing to the first electrode bands, and extended in a second direction interlacing the first direction. Each second electrode band is partially exposed by the first slits. The transparent dielectric material is disposed between the first electrode bands and the second electrode bands to provide a changeable gap.

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.

A pixel circuit relating to an organic light emitting diode (OLED) is provided by the invention, and if the circuit configuration (5T1C or 6T1C) thereof collaborates with suitable operation waveforms, the current flowing through an OLED in the OLED pixel circuit is not be changed along with variation of a power supply voltage (Vdd) influenced by the IR drop, and is not be varied along with the threshold voltage (Vth) shift of a TFT used for driving the OLED. Accordingly, the brightness uniformity of the applied OLED display can be substantially improved.

A pixel circuit comprises a driving transistor, an electroluminescent unit, a pre-write unit, and a write unit. The electroluminescent unit is controlled by the driving transistor to illuminate in a drive period. The write unit is enabled in a write period recording a data voltage relating to an initial threshold voltage of the electroluminescent unit in first storage element. The pre-write unit is enabled in a pre-write period recording a threshold voltage of the driving transistor and the electroluminescent unit in second storage element. The threshold voltage and the data voltage, stored in the first and the second storage units, are supplied as a gate-source voltage of the driving transistor, so as to provide a compensated drive voltage, capable of compensating the variation of the threshold voltages of the driving transistor and the electroluminescent unit, driving the electroluminescent unit.
