What is a screen?

Definition of a screen A screen is a device used to display information or images, and is the primary means of interaction between a user and a machine. Types of Display Screens Screens vary in type to include LCD, LED, and OLED, and each type has its own advantages and disadvantages. People use screens for a wide range of uses, including gaming, watching movies, and working. Choosing the right screen depends on the different needs and requirements of each user. Screen size and resolution are important factors that greatly determine the user experience.

History of the development of screens

Invention of Old Screens Old screens started with cathode technology, which was large and consumed a lot of power. At that time, the quality was limited, and the images were affected by distortion. The development of technology in today's screens Today, technology has developed tremendously, which has led to the emergence of more efficient screens, such as LCD, LED, and OLED screens. These modern types provide high image quality, wide viewing angles, and lower power consumption. This improvement in technology has contributed to enhancing the user experience, making screens an integral part of daily life.

Screen components

Display Panel The display panel is the main part of the screen and contains millions of pixels that display images. The image quality of the screen depends on the type of display panel used, whether LCD or OLED, as each offers its own advantages. Light source The light source is the element that provides the necessary illumination to display the image. In LCD screens, LED backlights are used, while OLED screens use self-illuminating technology, which increases efficiency and energy. This technology enhances the brightness of colors and the depth of shadows, which contributes to a better viewing experience.

Screen resolution and how to measure it

Screen Resolution Concept Screen resolution refers to the number of pixels on a screen, and it represents the amount of detail that can be displayed. The higher the resolution, the clearer the image, which improves the viewing experience. Users consider that a high-resolution screen shows details better and clearer. The most prominent standards for measuring screen resolution The most prominent standards for measuring screen resolution are the aspect ratio, such as 1920x1080 (Full HD) or 3840x2160 (4K). 8K resolution is also the latest, as it contains a larger number of pixels. It is important to choose the appropriate screen resolution according to personal or professional use.

Screen effects on the eye
