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.
