Abstract
A method for displaying an image on an image displaying device includes the steps of: comparing gray scale level of an image signal for the light emitting element with given threshold level; and when the gray scale level is higher than the threshold level, driving the light emitting element by a driving signal corresponding to the gray scale level, and when the gray scale level is lower than the threshold level, driving the light emitting element by a dithering driving signal including a driving signal corresponding to the threshold level.
Claims20
A method for displaying an image on an image displaying device, the method comprising:
- comparing a gray scale level of an image signal for a light-emitting element of the image displaying device with a given threshold level, wherein the given threshold level is based on a type of the image and a total luminance of the image;
- driving, when the gray scale level is higher than the given threshold level, the light-emitting element by a first driving signal corresponding to the gray scale level;
- and
- driving, when the gray scale level is lower than the given threshold level, the light-emitting element by a dithering driving signal including a second driving signal corresponding to the given threshold level.
An apparatus for displaying an image on an image displaying device, the apparatus comprising:
- a memory configured to store instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to cause the apparatus to:
- determine a given threshold level based on a type of the image and a total luminance of the image;
- compare a gray scale level of an image signal for a light emitting element of the image displaying device with the given threshold level;
- select a first driving signal corresponding to the gray scale level when the gray scale level is higher than the given threshold level;
- or
- select a dithering driving signal including a second driving signal corresponding to the given threshold level when the gray scale level is lower than the given threshold level;
- and
- drive the light emitting element by the first driving signal or the dithering driving signal.
A computer program product comprising computer-executable instructions for displaying an image on an image displaying device, the computer-executable instructions stored on a non-transitory computer-readable storage medium, wherein the computer-executable instructions when executed by one or more processors of an apparatus, cause the apparatus to:
- determine a given threshold level based on a type of the image and a total luminance of the image;
- compare a gray scale level of an image signal for a light emitting element of an image displaying device with the given threshold level;
- select a first driving signal corresponding to the gray scale level when the gray scale level is higher than the given threshold level;
- or
- select a dithering driving signal including a second driving signal corresponding to the given threshold level when the gray scale level is lower than the given threshold level;
- and
- drive the light emitting element by the first driving signal or the dithering driving signal.
