Embodiment Construction

[0034]Hereinafter, exemplary embodiments of the present invention will be explained in detail with reference to the accompanying drawings.

[0035]FIG. 1 is a block diagram showing an exemplary embodiment of a driving circuit for a display apparatus according to the present invention, and FIG. 2 is a representation useful in explaining a driving method of the driving circuit shown in FIG. 1.

[0036]Referring to FIG. 1, a driving circuit 100 for a display apparatus includes an image signal discriminator 110, an original image signal extractor 120, a memory 130, an image signal converter 140, a data outputter 150, and a frequency modulator 160.

[0037]The image signal discriminator 110 receives an image signal from an external system (not shown) and discriminates whether the image signal is a normal image signal used to display a normal video image or a film image signal used to display a film image. On the assumption that the display apparatus is applied to a television set, the normal imag...

Abstract

In a driving method of a display apparatus using a driving circuit, when an image signal is a film image signal, first, second, and third original image signals are extracted based on the film image signal. Then, a first compensation image signal is generated based on first and second original image signals, and a second compensation image signal is generated based on second and third original image signals. The first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are sequentially output to have a driving frequency higher than an input frequency. In addition, the first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are output i, k, j, and k times, respectively. Thus, a trembling phenomenon perceived by a viewer of a film image may be prevented.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a Divisional Application of U.S. patent application Ser. No. 12 / 356,584, filed on Jan. 21, 2009, and claims priority to and the benefit of Korean Patent Application No. 2008-80064 filed on Aug. 14, 2008, the entire contents of both of which are incorporated by reference herein.BACKGROUND[0002]1. Technical Field The present disclosure relates to a method of driving a display apparatus and a driving circuit for a display apparatus using the driving method, which are capable of preventing a trembling phenomenon of a film image.[0003]2. Discussion of Related Art[0004]In general, a display apparatus receives image signals from an external system and displays images corresponding to the image signals on a screen.[0005]The display apparatus, recently, has been applied to various fields, and thus the display apparatus displays not only a normal video image but also a film image that was recorded in photographic film.[0006]Becau...
