Abstract
An electronic apparatus is disclosed. The electronic apparatus includes a display including a plurality of scan lines arranged in one direction, a plurality of data lines arranged in a direction perpendicular to the plurality of scan lines, a pixel generated in an intersection area of the scan lines and the data lines, and one or more processors configured to provide the scan signal to the plurality of scan lines in an interlaced scanning method based on the image frame being an image in which a first pixel line having high-luminance greater than or equal to a threshold luminance and a second pixel line having low-luminance less than the threshold luminance are alternately arranged.
Claims15
An electronic apparatus comprising:
- a display including a plurality of scan lines arranged in a first direction, a plurality of data lines arranged in a second direction perpendicular to the first direction, and a plurality of pixels, each of the plurality of pixels being located an intersection of one of the plurality of scan lines and one of the plurality of data lines;
- and
- one or more processors configured to:
- provide a scan signal to the plurality of scan lines based on a progressive scanning method during a time period corresponding to an image frame, and provide an image signal corresponding to the image frame to a data line corresponding to a scan line, among the plurality of scan lines, to which the scan signal is provided, and
- change from the progressive scanning method to an interlaced scanning method based on identifying that the image frame includes a first pixel line having a first luminance greater than or equal to a reference luminance and a second pixel line having a second luminance less than the reference luminance are alternately arranged, and
- after changing from the progressive scanning method to the interlaced scanning method, to provide the scan signal to the plurality of scan lines in the interlaced scanning method to provide a current to the display in a waveform having a frequency in the audible frequency range and having an amplitude less than a threshold amplitude,
- wherein the first pixel line and the second pixel line are in a same direction as the scan line, and
- wherein the one or more processors is further configured to vary the threshold amplitude based on at least one of an installation environment of the electronic apparatus, a type of content provided by the electronic apparatus or user setting.
A method of controlling an electronic apparatus comprising a plurality of scan lines arranged in a first direction, a plurality of data lines arranged in a second direction perpendicular to the first direction, and a plurality of pixels, each of the plurality of pixels being located an intersection of one of the plurality of scan lines and one of the plurality of data lines, the method comprising:
- providing a scan signal to the plurality of scan lines based on a progressive scanning method during a time period corresponding to an image frame;
- and
- providing an image signal corresponding to the image frame to a data line corresponding to a scan line, among the plurality of scan lines, to which the scan signal is provided;
- changing from the progressive scanning method to an interlaced scanning method based on identifying that the image frame includes a first pixel line having a first luminance greater than or equal to a reference luminance and a second pixel line having a second luminance less than the reference luminance are alternately arranged;
- after changing from the progressive scanning method to the interlaced scanning method, providing the scan signal to the plurality of scan lines in the interlaced scanning method to provide a current to the display in a waveform having a frequency in the audible frequency range and having an amplitude less than a threshold amplitude,
- wherein the first pixel line and the second pixel line are in a same direction as the scan line, and
- wherein the threshold amplitude is varied based on at least one of an installation environment of the electronic apparatus, a type of content provided by the electronic apparatus or user setting.
