LCD (Liquid Crystal Display) is a type of display that uses liquid crystals to display an image. It is a flat screen panel used in many electronic devices, including televisions, monitors, mobile phones, tablets and other devices.

The principle of LCD operation consists in controlling the passage of light through layers of liquid crystals, which are located between two polarizers. These liquid crystals change their molecular orientation under the influence of electrical voltage, thereby changing the passage of light through the individual pixels of the screen. Different combinations of on and off pixels create an image and display color information.

LCD displays are popular for their advantages such as low power consumption, thin profile, high contrast, clear image and wide viewing angles. These displays can also support different resolutions and color modes, allowing for accurate and detailed viewing.

With the development of technology, various types of LCD displays have been developed, including TFT-LCD (Thin-Film Transistor LCD), IPS-LCD (In-Plane Switching LCD), OLED (Organic Light Emitting Diode) and others. Each type has its own characteristics and advantages in terms of brightness, contrast, colors and response time.

LCD displays are currently widely used in various consumer electronic devices and provide a high-quality visual display. Their use also extends to other areas, such as digital information boards, automotive displays and other applications where accurate and attractive image display is required.
