摘要： An object of the present invention is to provide a level shift IC with a reduced number of input signals over the conventional case. A level shift IC includes an amplitude converting unit including four level shifters; and a different-phase signal generating unit at a stage previous to the amplitude converting unit, including delay circuits. The different-phase signal generating unit generates, by the delay circuits, first and second delayed input signals from first and second input signals of different phases. Therefore, four input signals of different phases are obtained, and the amplitude converting unit increases the amplitudes of the input signals by the amplitude converting unit and thereby generates first to fourth output signals with different phases and increased amplitudes.

摘要： Each stage of first and second shift registers outputs a scan pulse by transferring a clock pulse of a clock signal supplied through a first clock input terminal. A first transistor is provided in at least one embodiment so as to connect and disconnect a scan signal line corresponding to the individual stage to and from a low-level power source of the scan pulse, and the first transistor has a gate that receives a clock signal supplied through a second clock input terminal. Two clock signals supplied to the first shift register and two clock signals supplied to the second shift register are different from each other in timings of their clock pulses. This realizes a display device capable of curbing the phenomenon in which a threshold voltage of a sink-down transistor is shifted, while sinking the gate line voltage down.

摘要： In one embodiment of the present invention, a liquid crystal panel driving device for AC-driving a liquid crystal panel with first and second polarities includes an output tone generating section for generating an output tone corresponding to an input tone. With respect to the same input tone, the output tone generating section generates a first output tone when driving the liquid crystal panel with a first polarity, and generates a second output tone when driving the liquid crystal panel with a second polarity. The first and second output tones are determined based on a characteristic of the input tone and the center of amplitude of a voltage to be outputted in response to the input tone in AC driving. This allows providing a liquid crystal panel driving device capable of easily performing Ω correction with respect to each liquid crystal panel.
