    摘要: Provided is a method of driving a liquid crystal display apparatus, and more particularly, to a method of generating a frame start pulse signal for instructing driving of a specific function of a source driver in a source driver chip of a liquid crystal display apparatus. Accordingly, by generating a frame start pulse signal for instructing driving of a specific function of a source driver in a source driver chip unlike a conventional method where the frame start pulse signal is externally input, it is possible to reduce the number of input pins for inputting the frame start pulse signal and to remove an input line for inputting the frame start pulse signal in a process of mounting the source driver chip in a printed circuit board.

    摘要: Disclosed are an offset compensation gamma buffer and a gray scale voltage generation circuit using the same. The offset compensation gamma buffer includes: a buffer which outputs an input voltage input to a positive or negative input terminal as an output voltage; and a switching unit which selectively connects the input voltage and the output voltage of the buffer to the positive and negative input terminals in response to a control signal. The output voltage of the offset compensation gamma buffer is supplied to the input of a gray scale voltage generation circuit of a source driver for driving a liquid crystal panel. The offset of the offset compensation gamma buffer is compensated using an inversion timing of the control signal. The output voltage of the offset compensation gamma buffer is supplied as a reference voltage of the voltage divider unit for generating the gray scale voltages, and the offset of the gray scale voltages is also compensated.
