PROMAX120W24V5A electrical components Germany PROMAX120W24V5A model PROMAX120W24V5A price

PROMAX120W24V5A electrical component is an electronic device with three terminals, made of three parts of semiconductors with different doping levels. The charge flow in the transistor is mainly due to the diffusion and drift motion of carriers at the PN junction. This type of transistor operation involves the flow of both electrons and holes, so it is called bipolar, also known as a bipolar junction transistor. This mode of operation differs from unipolar transistors such as field-effect transistors, whose operation involves only the drift of one type of carrier. The boundary between two regions with different dopants is formed by the PN junction. Bipolar transistors can amplify signals and have good power control, high-speed operation, and durability, so they are often used to form amplifier circuits or drive devices such as speakers and motors, and are widely used in aerospace engineering, medical devices, and robotics applications.

1. LCD panel: The LCD panel includes polarizing film, glass substrate, black matrix, color filter, protective film, common electrode, alignment layer, liquid crystal layer (liquid crystal, spacers, sealant), capacitor, display electrode, prism layer, and diffuser layer. The polarizing film, also known as a polarizer, is divided into an upper polarizer and a lower polarizer. The polarization functions of the upper and lower polarizers are perpendicular to each other. They act like a fence, blocking light wave components perpendicular to the polarizer's axis while allowing only those parallel to pass through. 2. Glass substrate: In liquid crystal displays, glass substrates are divided into upper and lower substrates. Their main function is to hold the liquid crystal material in the space between the two substrates. The glass substrate material is generally alkali-free borosilicate glass with excellent mechanical properties, heat resistance, and chemical corrosion resistance. For TFT-LCD, one glass substrate is distributed with TFT, while the other glass substrate is deposited with a color filter. 3. Black matrix: The black matrix uses highly light-shielding materials to separate the red, green, and blue primary colors in the color filter (to prevent color mixing) and prevent light leakage, thereby improving the contrast of each color block. In addition, in TFT-LCD, the black matrix can conceal internal electrode wiring or thin-film transistors. The color filter, also known as a color film, generates 3 primary colors of light (red, green, and blue) to achieve full-color display on the LCD. 4. Alignment layer: The alignment layer, also known as the orientation layer or directing layer, ensures that liquid crystal molecules are uniformly arranged and oriented at the microscopic level. 5. Transparent electrode: Transparent electrodes are divided into common electrodes and pixel electrodes. The input signal voltage is applied between the pixel electrode and the common electrode. Transparent electrodes are typically formed by depositing indium tin oxide (ITO) material on the glass substrate to create a transparent conductive layer. 6. Liquid crystal material: In LCD, the liquid crystal material acts like a light valve, controlling the brightness of transmitted light to achieve information display. 7. Driver IC: The driver IC is a set of integrated circuit chips used to adjust and control the phase, peak value, frequency, and other parameters of the potential signals on the transparent electrodes, establishing a driving electric field to ultimately realize information display on the LCD. In LCD panels, active matrix LCDs are constructed by sealing twisted nematic (TN) liquid crystal material between two glass substrates. The upper glass substrate (closer to the display screen) is deposited with red, green, and blue (RGB) color filters (or color films), a black matrix, and a common transparent electrode. The lower glass substrate (farther from the display screen) is equipped with thin-film transistor (TFT) devices, transparent pixel electrodes, storage capacitors, gate lines, signal lines, etc. Alignment layers (or orientation layers) are prepared on the inner sides of the two glass substrates to orient the liquid crystal molecules. Liquid crystal material is injected between the two glass substrates, and spacers are distributed to ensure uniform gap thickness. The periphery is bonded with frame glue for sealing, and the common electrodes of the upper and lower glass substrates are connected using silver dot adhesive technology. Polarizers (or polarizing films) are attached to the outer sides of the upper and lower glass substrates, respectively. When a voltage is applied between the pixel transparent electrode and the common transparent electrode, the arrangement state of the liquid crystal molecules changes. Consequently, the intensity of incident light passing through the liquid crystal also changes. LCDs utilize the optical rotation property of liquid crystal materials combined with electric field control to achieve information display. 8. Backlight module: LCD products are non-emissive electronic devices that do not emit light themselves. They rely on the light emission from the source in the backlight module to achieve display performance. Therefore, the brightness of LCD is determined by its backlight module. Thus, the performance of the backlight module directly affects the display quality of the LCD panel. The backlight module includes illumination sources, reflectors, light guide plates, diffuser sheets, brightness enhancement films (prism sheets), and frames. Backlight modules for LCD are mainly classified into edge-lit and direct-lit types. Mobile phones, laptops, and monitors (15 inches) mainly use edge-lit backlight modules, while LCD TVs mostly use direct-lit backlight module sources. Cold cathode fluorescent lamps and light-emitting diodes are the main backlight sources for LCD. 9. Reflector: The reflector, also known as the reflector cup, mainly functions to direct all light emitted by the source into the light guide plate, minimizing unnecessary loss. 1. Light guide plate: The main function of the light guide plate is to guide light from the side source to the front of the panel. 11. Prism sheet: The prism sheet, also known as a brightness enhancement film, mainly functions to concentrate scattered light through refraction and total reflection within the film layer, emitting it from the backlight source at a specific angle to enhance screen brightness.12. Diffuser sheet: The main function of the diffuser sheet is to correct the edge-lit light from the backlight module into a uniform surface light source to achieve optical diffusion. Diffuser sheets are categorized into upper and lower diffuser sheets. The upper diffuser sheet is located between the prism sheet and the LCD assembly, closer to the display panel. The lower diffuser sheet is located between the light guide plate and the prism sheet, closer to the backlight source.

PROMAX120W24V5A electrical component function

The main functions of potentiometers in circuits include: 1. Used as a voltage divider. A potentiometer is a continuously adjustable resistor. When adjusting the knob or slider of the potentiometer, the movable contact slides on the resistive body. At this time, the output terminal of the potentiometer provides an output voltage related to the external voltage applied to the potentiometer and the angle or travel of the movable arm. 2. Used as a variable resistor. When a potentiometer is used as a variable resistor, it should be connected as a two-terminal device. This allows for a smoothly and continuously changing resistance value within the travel range of the potentiometer. 13. Used as a current controller. When a potentiometer is used as a current controller, one of the selected current output terminals must be the terminal connected to the sliding contact.

Some gas discharge tubes use glass as the tube enclosure, while others use ceramic. The discharge tube is filled with inert gases with stable electrical properties (such as argon and neon). Common discharge tubes have two or three electrodes, separated by inert gas. Based on the number of electrodes, discharge tubes are classified into two-electrode and three-electrode types. Ceramic two-electrode discharge tubes consist mainly of pure iron electrodes, nickel-chromium-cobalt alloy caps, silver-copper welding caps, and ceramic tube bodies. The discharge electrodes inside the tube are coated with radioactive oxides, and the inner wall of the tube is also coated with radioactive elements to improve discharge characteristics. Discharge electrodes mainly come in rod and cup structures. In discharge tubes with rod-shaped electrodes, a cylindrical heat shield is installed between the electrode and the tube wall. This heat shield ensures uniform heating of the ceramic tube body, preventing local overheating and tube fracture. The heat shield is also coated with radioactive oxides to further reduce discharge dispersion. In discharge tubes with cup-shaped electrodes, a molybdenum mesh is installed at the cup opening, and cesium element is placed inside the cup, also serving to reduce discharge dispersion. Three-electrode discharge tubes are also composed of pure iron electrodes, nickel-chromium-cobalt alloy caps, silver-copper welding caps, and ceramic tube bodies. Unlike two-electrode discharge tubes, three-electrode discharge tubes add a nickel-chromium-cobalt alloy cylinder as the third electrode, i.e., the ground electrode.
