Title:
DISPLAY DEVICE CAPABLE OF SCREEN DISTORTION CORRECTION AND SCREEN DISTORTION CORRECTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/029836
Kind Code:
A1
Abstract:
A display device according to the present invention includes: an input part for receiving image data; a record part for processing and recording the image data; a storage part for storing the recorded image data in a frame/line buffer; a reading part for reading out the stored image data; and an output part for outputting the read image data, wherein the reading part includes a backward mapper for generating distortion-reflected image data by using two different LUTs. According to the present invention, it is possible to realize a display device that is very advantageous in terms of processing speed and power consumption by remarkably reducing an amount of calculations required to correct screen distortion. Furthermore, the screen distortion correction is possible only with a very simple configuration and thus it is possible to achieve reduction of size and weight of a wearable device.
