Abstract

A display apparatus includes a signal receiving part to receive an image signal, a signal processing part to process the image signal, an OSD (on screen display) generating part to generate an OSD signal, a control part to detect the image signal inputted through the signal receiving part to determine a source of the image signal, to set setup data to conduct signal processing of the signal processing part based on a result of the source determination, and to generate (or to produce or to trigger) an OSD display event for the OSD generating part, and a display module including a display panel, a pattern storing part to store a predetermined test pattern, and a panel driving part to drive the display panel to display the test pattern if a signal from the signal processing part is abnormal.

Description

[0001] This application claims priority to Korean Patent Application No. 2006-0010823 filed with the Korean Intellectual Property Office on February 3, 2006, the entire disclosure of which is incorporated herein by reference, based on 35 USC § 119(a). technical field [0002] The present general inventive concept relates to a display device and a control method thereof, and more particularly, to a display device provided with a display module having a BIST (Built in Self Test) mode and a control method thereof. Background technique [0003] In general, the BIST mode means a self-test (eg, stand-alone) mode that self-tests whether a module works normally. [0004] If no normal signal is input or an abnormal signal is input, the display module using the BIST mode displays a predetermined test pattern by cooperating with the BIST mode. [0005] Even if the display module does not have a normal input image signal for display, the displayed test pattern indicates whether the disp...
