What material is the display made of?
The main electronic components inside a display screen are crucial for its normal operation and display effect. Here is a detailed explanation of these components:
Main component
The display unit is the core part of the display screen. For LED displays, it consists of numerous LED lamps, each of which can display a color (usually red, green, and blue). For LCD screens, the display unit is composed of a liquid crystal layer and a backlight module, with the liquid crystal layer controlling the passage of light and the backlight module providing the light source.
The scan control board is responsible for processing display data and generating scan signals for controlling LED lamps or liquid crystal pixels. It also controls the grayscale, which is the brightness level of the pixels, to achieve smoother color transitions.
The switching power supply is a power adapter that converts alternating current (AC) to direct current (DC), providing stable voltage and current for the display screen to ensure its stable operation.
Transmission cables are responsible for transferring display data and control signals generated by the main control unit to the display screen. These cables must be able to withstand high-bandwidth data transmission to ensure image clarity and synchronization.
The main control unit is the brain of the display screen. It processes the input video signal, performs buffering, grayscale transformation, and signal reorganization, and then generates control signals to drive the display screen.
These cards are responsible for converting signals from computers or other video sources into formats suitable for the display screen, including RGB signals and synchronization signals.
The driver IC is an integrated circuit that controls the potential of each pixel in the display screen, thereby controlling the activation and deactivation of pixels to achieve image display.
Polarizers are used to control the polarization direction of light, ensuring that only light in a specific direction can pass through, which is crucial for the display effect of LCD screens.
Glass substrates are the supporting structure of liquid crystal displays, with liquid crystal materials sandwiched between two glass substrates.
The black matrix is a light-absorbing material used to separate pixels of different colors, preventing color mixing and enhancing the contrast of the display screen.
The color filter includes red, green, and blue filters, which work with the liquid crystal layer to produce full-color display.
The orientation film is an important part of the LCD layer of the display, and its role is to provide an orderly arrangement of the liquid crystal molecules to achieve the orientation of the liquid crystal, so as to control the light transmission or blocking, forming a visible image.
Transparent electrodes are layers of transparent conductive materials used to apply an electric field that controls the arrangement of liquid crystal molecules.
Liquid crystal materials are a type of fluid crystal that is sensitive to electric fields. By changing the electric field, they can control the passage of light, achieving the effect of image display.
These electronic components and materials work together to enable the display screen to accurately display images and videos. Each component has its specific function and is crucial for the performance and reliability of the display screen.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
