Abstract: A display has active elements and pixels arrayed in a matrix and drives the active elements to apply a voltage to the pixels for displaying an image. The display includes a gate driver IC for generating a signal for controlling the active elements, a plurality of gate interconnect lines for supplying the signal to the active elements, a source driver IC for generating a voltage to be applied to the pixels, a plurality of source interconnect lines for supplying the voltage to the pixels, and a switching circuit provided between the source driver IC and the plurality of source interconnect lines and having individually-switchable groups for supplying the voltage generated by the source driver IC to all of the source interconnect lines.

Abstract: With the prior art image-adjusting system for a liquid crystal display, flicker is adjusted by operator's visual examination and so human factors vary the potential-adjusting value applied to the common electrode. The invention provides an image-adjusting system and method free of this problem. The image-adjusting method starts with placing optical sensors opposite to a given location on a liquid crystal display. The output waveform from the optical sensors is observed on an oscilloscope in synchronism with the vertical synchronizing signal that is synchronized to odd frames or even frames. The potential applied to the common electrode of the liquid crystal display is shifted upward from the optimum potential to observe a first waveform. The potential on the common electrode is shifted downward from the optimum potential to observe a second waveform.
