US 12,183,259 B2 · Signal processing device and image display apparatus including same

Abstract

The present disclosure relates to a signal processing device and an image display apparatus including the same. A signal processing device according to an embodiment of the present disclosure includes: an input interface to receive an image signal; a first image processor to generate first image frame data based on the image signal; a second image processor to generate second image frame data scaled down from the first image frame data based on the image signal; and an output interface to receive the first image frame data from the first image processor and the second image frame data from the second image processor and to output the first image frame data and the second image frame data, wherein the first image frame data output from the output interface is more delayed than the second image frame data output from the output interface. Accordingly, a timing controller may accurately and rapidly perform signal processing for a panel.

Dependent claims

An image display apparatus comprising:

a display;
a signal processing device configured to, in case in which an image output mode is a first mode, transmit data of a first image frame and data of a second image frame to the display,
wherein a size of the second image frame is smaller than a size of the first image frame,
wherein the signal processing device is further configured to, in case in which the image output mode is a second mode in which delay of image transmission to the display is less than that of the first mode, transmit the first image frame data without the second image frame data to the display,
wherein the display comprises:
a timing controller configured to, in case in which the image output mode is the first mode, extract information regarding the first image frame data from the received second image frame data, perform signal processing on the first image frame data based on the extracted information, and output the processed the first image frame;
a panel configured to display an image based on the processed the first image frame from the timing controller.
