Can a TV Screen Be Used As a Camera?

In the modern age of technology, the convergence of devices and functionalities continues to redefine the boundaries of innovation. Among these advancements is the concept of utilizing TV screens not only for displaying images but also as cameras. In this introduction, we will explore the definition of TV screens and introduce the intriguing concept of repurposing them as cameras.

A TV screen, short for television screen, is the display component of a television set. It consists of a flat or curved panel that emits light to produce visual images, allowing viewers to watch television programs, movies, and other multimedia content. TV screens come in various sizes, resolutions, and technologies, including LCD (liquid crystal display), LED (light-emitting diode), OLED (organic light-emitting diode), and QLED (quantum dot LED).

Traditionally, TV screens have been passive receivers of visual information, relying on external sources such as broadcast signals, streaming devices, or connected peripherals to display content. However, recent technological advancements have enabled TV screens to take on a more active role by integrating camera functionality directly into their design. This innovative approach transforms TV screens into multifunctional devices capable of capturing, processing, and displaying visual imagery without the need for separate camera equipment.
