Seoul's Kookmin University researchers concluded a clinical study to verify the impact of TV panels of sleep, measuring the levels of the sleep-inducing hormone melatonin in 40 adult men and women divided into groups watching the same content on either LCD or LG's WOLED TVs. The researcher found that melatonin secretion fell 2.7% over two hours for the LCD group and it increased 8.1% in the OLED TV group. Melatonin rises in the evening to prepare the body for sleep, but the blue light emitted from displays disturbs the melatonin secretion as it confuses the body. As LCDs emit about twice as much blue light as OLEDs, it is not a surprise they have this effect on melatonin levels.

The contrast ratio of an LED display can often be adjusted or customized to suit the specific needs and preferences of the user. This flexibility allows for fine-tuning the display settings to achieve the desired level of contrast for different types of content or viewing environments. By adjusting the contrast ratio, users can optimize the display performance for various applications, such as gaming, video editing, or graphic design.
Several factors can impact the contrast ratio of an LED display, including the quality of the display panel, the brightness levels, the viewing angle, and the ambient lighting conditions. Higher-quality panels with advanced technologies, such as local dimming or HDR support, can deliver superior contrast ratios. Additionally, controlling the brightness and adjusting the settings based on the viewing environment can also affect the perceived contrast ratio.
When compared to other types of displays, such as LCD or OLED, LED displays typically offer a higher contrast ratio. LED technology allows for better control over the backlighting, resulting in deeper blacks and brighter whites. While OLED displays can achieve infinite contrast ratios due to their ability to turn off individual pixels, LED displays still provide excellent contrast performance and are more widely used in various applications.
There are industry standards and guidelines for contrast ratio in LED displays to ensure consistency and quality across different products. Organizations like the International Electrotechnical Commission (IEC) and the Society for Information Display (SID) have established criteria for measuring and reporting contrast ratios in displays. These standards help manufacturers and consumers assess the performance and capabilities of LED displays accurately.
The contrast ratio of an LED display can impact power consumption and energy efficiency.
