Abstract
The disclosure relates to display panel and electroluminescence display using the same. The display panel includes: a sub-pixel, which comprises a light-emitting element and a driving element for driving the light-emitting element, the light-emitting element emitting light by a current in the driving element during a driving phase; and a power switching circuit configured to supply a first driving voltage to the sub-pixel during the driving phase in an active period and a blanking interval, and supply a second driving voltage to the sub-pixel during a data writing phase of the active period and during resetting, sensing, and data writing phases of the blanking interval.
Claims12
A display panel, which displays frame data during a frame period including an active period and a blanking interval, and modulates data of an input image based on a result of sensing electrical characteristics of pixels in the blanking interval, the display panel comprising:
- a sub-pixel, the sub-pixel including a light-emitting element and a driving element configured to drive the light-emitting element to emit light based on a current in the driving element during a driving phase;
- and
- a power switching circuit configured to supply a first driving voltage to the sub-pixel during the driving phase in the active period and the blanking interval, and supply a second driving voltage to the sub-pixel during a data writing phase of the active period and during resetting, sensing, and data writing phases of the blanking interval.
An electroluminescence display, comprising:
- a display panel, which displays frame data during a frame period including an active period and a blanking interval, and modulates data of an input image based on a result of sensing electrical characteristics of pixels in the blanking interval, the display panel including:
- a sub-pixel, the sub-pixel including a light-emitting element and a driving element configured to drive the light-emitting element to emit light based on a current in the driving element during a driving phase;
- and
- a power switching circuit configured to supply a first driving voltage to the sub-pixel during the driving phase in the active period and the blanking interval, and supply a second driving voltage to the sub-pixel during a data writing phase of the active period and during reset, sensing, and data writing phases of the blanking interval.
