II. Consequences of Dim Laptop Screens, Insufficient Brightness
Light is one of the crucial factors directly impacting human health. So, how does prolonged use of a dim laptop screen affect health?
1. Encountering Visual Problems

Especially when the light is too dim, your eyes will consistently feel tired, watery, itchy, and may even lead to redness in some cases.
2. Encountering Sleep Issues
When you encounter a dim working environment, the light emitted from your laptop screen can potentially cause sleep problems such as: Startling awake, insomnia... The direct cause of this issue is the blue light spectrum, which inhibits melatonin production and disrupts the body's biological clock.
3. Encountering Cognitive Issues
If you have to work in a dimly lit environment for a long time, your eyes become strained, leading to stress on the brain. This harmful domino effect will quickly deteriorate your health, directly affecting the brain and other related parts.

Modern laptop models come with quick brightness adjustment keys on the toolbar as well as direct brightness control on the operating system.

A malfunctioning laptop screen causing reduced brightness is not a new issue for technicians. Encountering this problem indicates a deeper internal issue. Many laptop models suffer from backlight failures, where the screen gradually dims and eventually turns off after a certain period of use.
Meanwhile, many laptops experience board or circuit issues, causing the screen to not receive signals from the control software, resulting in random brightness levels…. For these cases, you need to seek out a service center to remove the screen and check whether the backlight panel is functioning properly.
