OLED Display Red Light Segmentation for Melatonin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional organic light emitting diode displays do not effectively enhance melatonin secretion, which is crucial for regulating biological rhythms, sleep, blood flow, and hormonal control.
Innovation Solution
The display incorporates a substrate with first and second red organic light emitting elements that emit light with different peak wavelengths, specifically in the range of 580 nm to 680 nm, to increase melatonin secretion by simulating the natural light spectrum that stimulates melatonin control cells in the human eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional organic light emitting diode displays use standard red light emission, then the display structure is simple, but melatonin secretion enhancement is insufficient
Solution Approach 1:
The red light emission is segmented into multiple wavelength components. The patent divides the red light emission into at least two distinct wavelength ranges (e.g., 610-680nm and 580-650nm) with different peak wavelengths, allowing each segment to contribute differently to melatonin secretion enhancement while maintaining overall red light functionality.
Solution Approach 2:
Different regions of the light emission spectrum are assigned different qualities. The patent employs multiple organic light emitting elements or emission regions with distinct peak wavelengths within the red spectrum, where each region emits light with specific wavelength characteristics optimized for different functions (display vs. melatonin enhancement).
2Reliability
If multiple red organic light emitting elements with different peak wavelengths are used, then melatonin secretion is enhanced, but device complexity increases
Solution Approach 1:
Multiple organic light emitting elements with different peak wavelengths are merged into a single display structure. The patent integrates multiple emission regions or elements into one cohesive display device, allowing simultaneous emission of different wavelength components from the same physical structure, thereby enhancing melatonin secretion without proportionally increasing device complexity.
Solution Approach 2:
The organic light emitting elements serve multiple functions. Each element not only contributes to the display function by emitting red light but also collectively performs the additional function of enhancing melatonin secretion. The light emitting elements are designed to fulfill both display requirements and health-related benefits simultaneously.

AI summary
An organic light emitting diode display includes a substrate and a first red organic light emitting element disposed on the substrate. The first red organic light emitting element may include a first light emission region and a second light emission region, wherein the first light emission region emits a first red light having a first peak wavelength, and the second light emission region emits a second red light having a second peak wavelength different from the first peak wavelength.
