Title:
DISPLAY DEVICE AND METHOD FOR CONTROLLING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/187565
Kind Code:
A1
Abstract:
This display device comprises a display panel whereon a plurality of pixels is disposed in a matrix, and a drive unit for driving the display panel on the basis of an input signal. The display device is characterized by including: a conversion unit that converts an original signal representing the luminance of the pixel into a brightened signal representing a luminance brighter than the luminance represented by the original signal and/or a darkened signal representing a luminance darker than the luminance represented by the original signal; a calculation unit that calculates the difference in luminance of the original signal between one pixel unit including at least one pixel and another pixel unit located next to the one pixel unit; a determination unit that determines whether or not the difference in luminance calculated by the calculation unit exceeds a threshold; a selection unit that selects the original signal for the one pixel unit if determined, by the determination unit, that the difference in luminance exceeds the threshold, and selects the brightened signal or the darkened signal for the one pixel unit if determined that the difference in luminance does not exceed the threshold; and an input unit that inputs an input signal based on the signal selected by the selection unit into the drive unit.
