Abstract
A display device includes a first pixel and a second pixel. The second pixel is controlled to emit light in a predetermined range in a first time period and to not emit light in the predetermined range in a second time period during which the first pixel emits light. The first pixel includes a first organic emission layer having a first thickness and the second pixel includes a second organic emission layer having a second thickness different from the first thickness. A resonance pattern is formed in the second pixel to emit light in a melatonin production inhibition wavelength range that corresponds to the predetermined range. The first pixel may emit blue light, green light, red light, or another color of light including white light.
Claims19
An organic light emitting diode (OLED) display device, comprising:
- a substrate;
- and
- three color pixels and a melatonin control pixel on the substrate,
- wherein the melatonin control pixel is to emit or block light in a melatonin production inhibition wavelength range, and wherein a thickness of an organic emission layer of the melatonin control pixel is different from a thickness of an organic emission layer of one or more of the three color pixels.
A display device, comprising:
- a signal line;
- and
- a first pixel connected to the signal line and having an organic emission layer with a thickness different from a thickness of an organic emission layer of another pixel, wherein the first pixel is to emit light in a predetermined range during a first time period and is not to emit light in the predetermined range during a second time period during which an image is displayed, wherein the second time period does not overlap the first time period, and wherein the predetermined range is a melatonin production inhibition wavelength range.
A display device, comprising:
- a first pixel to emit light;
- and
- a second pixel to emit light in a predetermined range in a first time period and to not emit light in the predetermined range in a second time period during which the first pixel emits light, wherein the first pixel includes a first organic emission layer having a first thickness and the second pixel includes a second organic emission layer having a second thickness different from the first thickness, and wherein a resonance pattern is formed in the second pixel to emit light in a melatonin production inhibition wavelength range that corresponds to the predetermined range.
