Abstract

Device and method for processing a signal to a display, the device including a horizontal synchronizing signal detecting part for detecting a horizontal synchronizing signal from a picture signal, and a mode determining part for determining a mode of the picture signal by using a cyclic period of the horizontal synchronizing signal.

Description

[0001] This application claims priority to Korean Application No. P2001-0040066 filed on July 5, 2001. technical field [0002] The present invention relates to displays, and more particularly to devices and methods for processing display signals. Background technique [0003] With reference to Fig. 1, the device of the prior art that is used to process display signal has: image signal receiving part 1, is used to receive the image signal of different signal modes; The horizontal synchronization signal is separated from the image signal; the microcomputer 3 is used to receive the horizontal synchronization signal separated by the horizontal synchronization signal separation part 2, and determine the mode of the image signal; the switching part 4 switches the image signal in response to the control signal of the microcomputer The first and the second signal processing parts 5 and 6 adopt different signal processing methods to process image signals according to the switching o...
