Abstract

An electronic device is provided. The electronic device includes a display including a plurality of pixels, and a processor, each of a plurality of pixels may include a plurality of sub pixels, the plurality of sub pixels may include first type pixels including first type sub pixels observed at a first viewing angle, and second type pixels being adjacent to the first type pixels and including second type sub pixels observed at a second viewing angle that is smaller than the first viewing angle, and the processor configured to, for a plurality of groups including first type pixels and second type pixels, perform a control such that turn-on ratios of the first type pixels and the second type pixels in, a plurality of groups, a first group are different from turn-on ratios of those of, among the plurality of groups, a second group that is different from the first group.

First claim

What is claimed is:

1 . An electronic device comprising:
a display including a plurality of pixels; memory, comprising one or more non-transitory storage media, storing instructions; and one or more processors communicatively coupled to the memory and the display, wherein the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to drive the display, wherein the plurality of pixels includes: first type pixels including first type sub pixels that are observed at a first viewing angle in a first direction, and second type pixels including second type sub pixels that are observed at a second viewing angle that is narrower than the first viewing angle in the first direction, and wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to: control turn-on ratios of the first type pixels and the second type pixels in a first group including a portion of the plurality of pixels differently from turn-on ratios of the first type pixels and the second type pixels in a second group including another portion of the plurality of pixels different from the first group in response to gradation values of partial areas of contents, while at least part of sub pixels including the first group is turned-on and at least part of sub pixels including the second group is turned-on in the partial areas of contents, drive the first type pixels that are adjacent to the second type pixels with second gradation values that are lower than first gradation values while the second type pixels are driven with the first gradation values corresponding to data in a private mode.

2 . The electronic device of claim 1 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
supply the second gradation values based on brightness correction information such that an average brightness of the first type pixels and the second type pixels that are adjacent to the first type pixels becomes a predefined target brightness value.

3 . The electronic device of claim 1 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
output a screen by turning on the first type pixels and the second type pixels when a setting of security is of a predefined first level, and drive the first type pixels with the second gradation values and drive the second type pixels with the first gradation values when the setting of the security is of a second level that is lower than the predefined first level.

4 . The electronic device of claim 3 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
output the screen by turning on the first type pixels and the second type pixels when the setting of the security is of the predefined first level, identify an external intensity of illumination when the setting of the security is of a second level that is higher than the predefined first level, supply a gradation value of 0 to the first type pixels and driving the second type pixels with the first gradation values when the external intensity of illumination is less than a first illumination intensity, and drive the second type pixels with the first gradation values while supplying the second gradation values to the first type pixels.

5 . An electronic device comprising:
a display including a plurality of pixels; memory, comprising one or more non-transitory storage media, storing instructions; and one or more processors communicatively coupled to the display and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to drive the display, wherein each of the plurality of pixels includes: a plurality of sub pixels, wherein the plurality of sub pixels include: first type pixels including first type sub pixels observed at a first viewing angle, and second type pixels being adjacent to the first type pixels and including second type sub pixels observed at a second viewing angle that is smaller than the first viewing angle, wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to: display a content by a plurality of groups including at least one pixel of the first type pixels and at least one pixel of the second type pixels, wherein the plurality of groups includes at least a first group and a second group, and wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to control turn-on ratios of the first type pixels and the second type pixels in the first group differently from turn-on ratios of the first type pixels and the second type pixels in the second group different from the first group in response to gradation values of partial areas of contents, in related to display of the content, while at least part of sub pixels including the first group is turned-on and at least part of sub pixels including the second group is tuned-on in the partial areas of contents.

6 . The electronic device of claim 5 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
turn on only the second type pixels when gradation values of partial areas of contents displayed by at least one of the plurality of groups are a maximum value.

7 . The electronic device of claim 5 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
set the turn-on ratios of the second type pixels to be higher when the gradation values of the partial areas of the contents displayed by at least one of the plurality of groups are relatively high.

8 . The electronic device of claim 5 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
set the turn-on ratios of the second type pixels to be lower when the gradation values of the partial areas of the contents displayed by at least one of the plurality of groups are relatively low.

9 . The electronic device of claim 5 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
classify region of an interest (ROI) area and a background area of the contents, when a luminance of the ROI area is lower than a luminance of the background area, set the turn-on ratios of the first type pixels in pixel groups disposed in the ROI area to be higher, and set the turn-on ratios of the first type pixels in pixel groups disposed in the background area to be lower.

10 . The electronic device of claim 9 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
when a text is displayed in the ROI area, set the turn-on ratios of the first type pixels in pixel groups disposed in an area, in which the text is displayed, to be lower, and set the turn-on ratios of the first type pixels in pixel groups disposed in an ROI background area around the text to be higher.

11 . The electronic device of claim 5 , wherein the instructions, when executed by the one or more processors individually or collectively, further cause the electronic device to:
make grouping sizes of the first ty
