Abstract
An apparatus for display an active region having a plurality of light-emitting elements, a gate scanning driver operatively coupled to the active region and configured to stop a gate scanning signal to the plurality of light-emitting elements in a period, and a light emitting driver operatively coupled to the active region and configured to cause the plurality of light-emitting elements to emit light in the period.
Claims18
An apparatus for display, comprising:
- an active region comprising a plurality of light-emitting elements;
- a gate scanning driver operatively coupled to the active region and configured to stop a gate scanning signal to the plurality of light-emitting elements for a period, the period comprising at least one frame;
- and
- a light emitting driver operatively coupled to the active region and configured to cause the plurality of light-emitting elements to emit light in the period, wherein
- the light emitting driver is configured provide a light emitting enable signal and a light emitting clock signal in the period and in another frame immediately prior to the period;
- the light emitting enable signal has a pulse signal in the at least one frame in the period, a width of the pulse signal is different from a width of another pulse signal in the other frame immediately prior to the period;
- and
- a scanning rate of the light emitting enable signal in the period is less than or equal to a scanning rate in the other frame.
An apparatus for display, comprising:
- an active region comprising a plurality of light-emitting elements;
- and
- a light emitting driver operatively coupled to the active region and configured to provide a light emitting signal that causes the plurality of light-emitting elements to emit light in a first period and a second period, wherein
- the light emitting signal comprises a light emitting enable signal that scans the plurality of light-emitting elements at a first scanning rate in the first period and a second scanning rate in the second period, the first scanning rate being higher than or equal to the second scanning rate;
- and
- of the light emitting enable signal, a width of a pulse signal in a frame in the first period is different from a width of another pulse signal in a frame in the second period.
A method for driving a plurality of light-emitting elements on a display panel, comprising:
- scanning the plurality of light-emitting elements in a first period;
- causing the plurality of light-emitting elements to emit light based on a data signal in the first period;
- retaining the data signal;
- scanning the plurality of light-emitting elements in a second period;
- applying, in the second period, a light emitting enable signal to the plurality of light-emitting elements, wherein determining the light emitting enable signal comprises
- determining a width of a first pulse signal in a first frame in the second period to be different from a width of another pulse signal in a frame in the first period such that a luminance corresponding to the first frame in the second period and a luminance corresponding to the frame in the first period are nominally the same;
- and
- causing the plurality of light-emitting elements to emit light based on the data signal and the light emitting enable signal;
- in the second period.
