Abstract: The present disclosure relates to an improvement in the quality of a transmitted signal, and more particularly, to an electronic apparatus and a method which are provided with a passive equalizer improving the quality of a transmitted signal when a signal is transmitted/received to/from an external apparatus, and a system for the same. The present disclosure provides a signal transmission system for improving the quality of a transmitted signal. The signal transmission system may include a transmitter that transmits a signal; a receiver that receives the signal from the transmitter; a channel that is formed between the transmitter and the receiver and transmits the signal delivered by the transmitter; and a passive equalizer that is formed between the transmitter and the receiver and controls the signal so as to have a higher impedence than a predetermined impedance at a lower frequency than a predetermined frequency of the signal.

Abstract: A driving device includes an output timing controller which controls an output timing of a first driving voltage and a second driving voltage respectively generated from a first voltage generator and a second voltage generator. A third driving voltage output from the output timing controller is provided to a first data driver and a second data driver, and also provided to a gamma voltage generator to generate a plurality of gamma voltages. Accordingly, a reverse electric potential between the third driving voltage and the gamma voltages is prevented from being generated in the first and second data drivers, therefore, preventing the first and second data drivers from being damaged.
