Explore the physics of LCDs and how they appear in car dashboard navigation screens
A liquid crystal display (LCD) is a visible light selective beam splitter, a thin-film liquid crystal material that isolates and controls incoming visible light, converting it into an image with defined color and brightness. The image of an LCD is made up of pixels, each controlled by liquid crystal molecules that can invert, twisting or blocking incoming light as the electric field changes.
The main physical characteristics of LCD include reflectivity, transmittance and absorptivity. Its transmittance varies with the electric field and can be adjusted by liquid crystal material selection. The change of reflectivity and transmittance depends on the incident angle of light, and the reflectivity decreases gradually with the increase of angle. In addition, the arrangement of liquid crystal molecules is also very important to the performance and appearance of LCD. Typically, they are arranged in parallel and adjacent states, known as family states, or in worm-like states, known as gear surface states.
Liquid crystal displays are an ideal display technology for car dashboard navigation screens because they provide high-quality images with extremely low power consumption. The low power consumption of liquid crystal displays makes them suitable for automotive electronic systems because it can extend battery life and reduce heat generation. In addition, LCDs are also very robust to withstand automotive vibrations and temperature changes, and their pixels can be integrated into very small spaces, making them suitable for small and large-screen automotive displays.
In automotive electronic systems, liquid crystal displays can be used in instrument panels, center consoles, navigation screens and rear entertainment systems. The LCD display on the instrument panel can display information such as vehicle speed, fuel level and water temperature. A display on the center console can be used to control audio, video, and vehicle settings, among other things. The navigation screen can provide information such as road maps and route planning. The rear entertainment system can provide content such as movies and games. Each application requires a specific pixel density and display area to maximize information readability.
Therefore, using LCD as a display technology for car dashboard navigation screens has many advantages. LCD displays not only have high-quality images and extremely low power consumption, but are also very robust to withstand car vibrations and temperature changes. The arrangement of liquid crystal molecules is also very important to its performance and appearance, providing different pixel densities and display areas for different applications, and can be integrated into very small spaces at once, making it suitable for small and large screens car monitor.
