Therefore, the choice of ideal brightness clearly depends directly on the brightness in the environment. A representative image for the case is shown in Fig.1. Similarly, while using our device in daylight, on a sunny day, we might need high brightness for us to view comfortably without any strain or harm. High brightness can be very harmful and straining for our eyes and low brightness is preferred in such situations. Consider the situation while checking our emails or working for office in a dark environment or at night like in Fig. In this proposed paper our main focus is on the aspect of managing the brightness in order to enhance the viewing experience of the user.īrightness is supposed to be modified dynamically in order to suit the environment of the user unlike other characteristics of the display. The size of the display, resolution and brightness are the main parameters to determine the quality of the screen. In many devices across the computing device spectrum, the display or the screen is used as the main user interface, including most traditional devices such as desktops and laptops. Keywords Automated brightness control, PC/Laptops, Brightness. The proposed technique was tested using hardware set up and the results prove that the lighting control reduces the strain on human eyes and increases comfort. The main advantage of the proposed model is that it not just brings the optimum viewing comfort to the user, in changing environmental lighting, but also helps to reduce power consumption and extend the battery life of the electronic device. To manage this health issue, this paper proposes a system which detects the intensity of light in the environment, just like the human eye does, and automatically changes the brightness in the electronic gadgets appropriately to bring down the strain on the eye. School of Computing Science and EngineeringĪbstract Bad environmental lighting or changing lights while watching television, or continuously working on a laptop or PCs, or while using headsets can bring a significant strain on the eyes. Vellore Institute of Technology Chennai, India Jishnu Saurav Mittapalli School of Computing Science and Engineering Step 1: Open Power OptionsĬlick on the Start button, then search for "Power Options" and launch the corresponding Control panel – Environment based Brightness Control However, what if you're not concerned about battery life and want the brightness as high as possible? Furthermore, the ambient light sensor is not perfect, and at times your display brightness can be in flux as described above. Thus, adaptive brightness is useful in conserving battery life since the display is a pretty power-hungry component. The adaptive brightness feature taps into the ambient light sensors to automatically adjust your display to match surrounding lighting conditions. Most displays, especially on laptops, utilize ambient light sensors to detect surrounding levels of light. In modern versions of Windows, Microsoft introduced a feature called adaptive brightness.

First of all, no, your laptop is not haunted, but more importantly, we're going to go into why this is happening and how to fix it. If this scenario sounds familiar, then I have some good news for you. Now you're confused and worried that your laptop is potentially haunted. Angered by this, you get up and move your laptop, only to suddenly notice that the display does in fact get a lot brighter.
You're smashing your keyboard to increase your screen brightness, yet it won't go any higher, but you know you've been able to set it higher before.
