OLED SCAN DRIVER DEVICE WITH CROSS-TALK ATTENUATION CIRCUIT

摘要

An OLED(Organic Light Emitting Diode) driving apparatus is provided to reduce crosstalk in a screen and to improve display quality by changing line impedance component in accordance with output status of a data driver and thus controlling the amount of the overall sink current. In an OLED driving apparatus, there are provided a plurality of scan drivers(130) and a plurality of data drivers(120). A crosstalk control unit(110) outputs a crosstalk timing control signal for controlling the crosstalk timing in accordance with the value of input data. A plurality of active impedance units(140) is connected to the scan drivers by matching in order to adjust the amplitude of an impedance applied to the scan drivers by the crosstalk timing control signal.
