Title:
IMAGE DISPLAY DEVICE AND ITS DRIVE METHOD
Document Type and Number:
WIPO Patent Application WO/2007/040088
Kind Code:
A1
Abstract:
An image display device includes: light emission means (OLED) emitting light
by electric connection; driver means (Td) having at least a first terminal and
a second terminal and controlling the light emission of the light emission means
according to a potential difference applied to the first terminal and the second
terminal; and control means for applying voltage to the first terminal or the
second terminal of the driver means (Td) during the light emission period of the
light emission means (OLED). The control means controls the voltage applied
to the first terminal or the second terminal of the driver means (Td) so as to be
different between a case when the light emission luminance of the light emission
means (OLED) is at a high gradation level and a case when the light emission luminance
of the light emission means (OLED) is at a low gradation level.
