"Screen" refers to a flat, rectangular display surface used to present visual information in electronic devices such as televisions, computers, smartphones, and tablets. It can be made of technologies like LCD, LED, OLED, or CRT, each offering varying levels of brightness, contrast, and energy efficiency. Screens are essential for viewing text, images, and videos, enabling user interaction through touch or graphical interfaces. They come in different sizes, resolutions (e.g., HD, 4K), and aspect ratios to suit various applications, from entertainment to professional work. Modern screens often feature slim designs, high refresh rates, and adaptive features like blue light reduction or HDR for enhanced visual comfort and quality.
