The present invention relates to a cosmetic composition for skin whitening.

Composition comprising allulose as active ingredient for skin whitening

An embodiment provides a pixel including: a first bank pattern on a substrate; a first electrode and a second electrode on the first bank pattern and extending in a first direction; an insulating layer on the first electrode and the second electrode; a plurality of light emitting elements on the insulating layer between the first electrode and the second electrode; a first contact electrode electrically connecting the first electrode and the light emitting elements; and a second contact electrode electrically connecting the second electrode and the light emitting elements. The first electrode and the second electrode may be spaced from each other in a second direction different from the first direction on the first bank pattern.

Pixel and display device including the same

A display device includes a display part, a degradation compensator that generates a first compensated grayscale value by compensating for a first grayscale value corresponding to a first pixel, and generates a second compensated grayscale value by compensating for a second grayscale value corresponding to a second pixel, and a data driver that generates a first data signal based on the first compensated grayscale value to supply the first data signal to the first pixel, and generates a second data signal based on the second compensated grayscale value to supply the second data signal to the second pixel. A second degradation curve is defined by a first degradation coefficient corresponding to a first degradation curve, and a second degradation coefficient corresponding to a first estimated degradation curve for the light conversion particles of a second color calculated by applying the first degradation curve.

Display device and degradation compensating method thereof

An optical compensation device includes a luminance measurer that measures display luminance of a display device including a plurality of areas. A gamma corrector corrects a gamma voltage so that a first area of the plurality of areas has a gamma characteristic corresponding to a target gamma value based on the display luminance, and calculates a gamma value for each of the plurality of areas based on the display luminance. An optical compensator calculates a compensation parameter for each grayscale based on the display luminance and the gamma value. A luminance deviation for each of plurality of areas of the display device is compensated based on the compensation parameter.

Optical compensation device, display device, and optical compensation method of display device

A display device according to an exemplary embodiment includes: a plurality of transistors disposed on a substrate; a plurality of pixel electrodes electrically connected to the plurality of transistors; a plurality of first color filters, a plurality of second color filters, and a plurality of third color filters disposed between the plurality of transistors and the plurality of pixel electrodes; and a plurality of main spacers and a plurality of sub-spacers disposed on the pixel electrode, wherein the plurality of main spacers and the plurality of sub-spacers are disposed to overlap selected portions of the plurality of first color filters in a plan view, respectively, and not to overlap the plurality of second color filters and the plurality of third color filters in a plan view.

Display device

Provided is a method of providing a melody recording based on a user humming melody in a user device. The method includes displaying a record button to be used to start recording of a humming melody of a user in response to an input of the user, and measuring a pitch of a sound that changes over time based on the humming melody of the user, and displaying a change in the pitch in real time. A region in which the change in the pitch is displayed includes at least a portion of a left region of a screen of the user device.

Method for providing a melody recording based on user humming melody and apparatus for the same

A display device is disclosed. In one embodiment, the display device includes a first conversion unit receiving gray data and outputting a gray data value of a second gamma curve, which has a luminance equal to a luminance of the gray data on a first gamma curve. The device may also include a memory storing a look-up table (LUT) which includes first and second data groups and compensated gray data for the second gamma curve. The device may further include a reference unit generating the compensated gray data based on the two converted gray data. Coordinates formed of i) each value in the first data group and ii) each value in the second data group may correspond to any one of the compensated gray data.

Display device including a gray compensator and method of driving the same

A liquid crystal display device includes a liquid crystal panel including a plurality of signal lines, a liquid crystal panel driving unit configured to provide a driving voltage to the plurality of signal lines, an image data judging unit configured to judge whether input image data is still image data or moving picture data, an image data correcting unit configured to correct moving picture data to output corrected moving picture to the liquid crystal panel driving unit, a plurality of light sources configured to provide a light to the liquid crystal panel, and a light source driving unit configured to detect a display region having a motion value larger than a reference value from among an image of which frame data is displayed, based on a comparison of current frame data of the moving picture data with previous frame data of the moving picture data.
