Organic light emitting diode display device

摘要

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.

主权项

1. 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.
