Title: Light-emitting device and its driving method
Inventor: YAMAZAKI SHUNPEI
IPC: H01L51/50
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To propose a light-emitting device which facilitates the recognition of a physical object even when an image itself which a video signal inputted into the light-emitting device has as information is dark or indistinct as a whole. SOLUTION: In at least one display period within a single-frame period, the absolute value of the EL driving voltage applied between the pixel electrode and the counter electrode is made temporarily larger to increase the brightness of an EL device. That is, the difference between the power source electrical potential and the opposite electrical potential in all display periods is not always kept constant, but the absolute value of the difference between the power source electrical potential and the opposite electrical potential in a certain fixed period within at least one display period (strong emission period) is made larger than the difference of the potential of other periods to make the brightness of the EL element higher.  In this configuration, the actually displayed image becomes brighter even if the image itself which the video signal inputted into the light- emitting device has as information is dark on the whole, and hence recognition of the physical object is facilitated.
