MINIB electrical components, German MINIB models, MINIB prices

MINIB electrical components are Zener diodes manufactured to provide voltage regulation by utilizing the reverse breakdown state of a PN junction, where the current can vary over a wide range while the voltage remains essentially constant. This diode is a semiconductor device that exhibits very high resistance up to the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance drops to a very low value; in this low-resistance region, the current increases while the voltage remains constant. Zener diodes are graded according to their breakdown voltage. Due to this characteristic, Zener diodes are primarily used as voltage regulators or voltage reference elements. Zener diodes can be connected in series for use at higher voltages, allowing for higher stabilized voltages through series connection.

MINIB electrical component operating principle

LCD is a display that uses liquid crystal as the material. Liquid crystals are a class of organic compounds intermediate between solid and liquid states. At room temperature, they exhibit both the fluidity of liquids and the optical anisotropy of crystals. They become a transparent liquid when heated and a crystalline, turbid solid when cooled. Under the influence of an electric field, the arrangement of liquid crystal molecules changes, thereby affecting the intensity of incident light passing through the liquid crystal. This change in light intensity is further manifested as a change in brightness through the action of polarizers. Accordingly, by controlling the electric field applied to the liquid crystal, variations in light brightness can be achieved, thus accomplishing information display. Therefore, the function of liquid crystal material is analogous to individual small "light valves." Since control circuits and drive circuits exist around the liquid crystal material, when electrodes in the LCD generate an electric field, the liquid crystal molecules twist, causing regular refraction of the light passing through them (due to the optical activity of the liquid crystal material), which is then filtered by a second polarizer and displayed on the screen. It is worth noting that because liquid crystal material does not emit light itself, LCD displays typically require an additional light source configured for the display panel. The main light source system is called the "backlight module," in which the backlight plate is composed of fluorescent materials that emit light, primarily providing a uniform backlight source.

MINIB electrical component classification

Classification by application: toggle switches, band switches, record/playback switches, power switches, selector switches, limit switches, control switches, changeover switches, isolating switches, travel switches, wall switches, intelligent fire protection switches, etc. Classification by structure: micro switches, rocker switches, toggle switches, slide switches, push-button switches, key switches, as well as fashionable thin-film switches and tactile switches. Classification by contact type: switches can be divided into a type contacts, b type contacts, and c type contacts based on contact type. Contact type refers to the relationship between the operational status ("contacts close when the switch is operated/pressed") and the contact state. Suitable contact types must be selected according to the application. Classification by number of switches: single-control switches, dual-control switches, multi-control switches, dimmer switches, speed control switches, splash-proof boxes, doorbell switches, sensor switches, touch switches, remote control switches, smart switches, card-insertion power switches, and dedicated switches for bathroom heaters.

MINIB electrical component structure

1. LCD panel: The LCD panel includes polarizing films, glass substrates, black matrix, color filters, protective films, common electrodes, alignment layers, liquid crystal layer (liquid crystal, spacers, sealant), capacitors, display electrodes, prism layers, and diffusing layers. Polarizing films, also known as polarizers, are divided into upper and lower polarizers. The polarization functions of the upper and lower polarizers are perpendicular to each other. They act like gratings, blocking light wave components perpendicular to the polarizer grating while allowing only those parallel to the grating to pass, as required. 2. Glass substrates: 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 material for glass substrates 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 color filters. 3. Black matrix: The black matrix uses highly light-blocking materials to separate the red, green, and blue primary colors in the color filters (preventing color mixing) and to prevent light leakage, thereby improving the contrast of each color block. Additionally, in TFT-LCD, the black matrix can conceal internal electrode wiring or thin-film transistors. Color filters, also known as color filter membranes, function to produce the 3 primary colors of red, green, and blue, enabling full-color display on the liquid crystal display. 4. Alignment film: The alignment film, also known as the orientation film or alignment layer, functions to achieve uniform arrangement and orientation of liquid crystal molecules at the microscopic level. 5. Transparent electrodes: Transparent electrodes are divided into common electrodes and pixel electrodes. The input signal voltage is applied between the pixel electrodes and the common electrodes. Transparent electrodes are typically formed by depositing indium tin oxide (ITO) material on glass substrates to create a transparent conductive layer. 6. Liquid crystal material: In LCD, liquid crystal material acts similarly to a light valve, controlling the brightness of transmitted light to achieve information display. 7. Drive IC: Drive IC is essentially a set of integrated circuit chip devices 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 liquid crystal. In liquid crystal panels, active-matrix liquid crystal displays 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) tricolor color filters (also known as color filter membranes), a black matrix, and common transparent electrodes. The lower glass substrate (the 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 films (or alignment 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 dispersed to ensure uniform gap thickness. The periphery is bonded with frame adhesive for sealing, and the common electrodes of the upper and lower glass substrates are connected using silver dot paste 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 electrodes and the common transparent electrodes, the arrangement state of the liquid crystal molecules changes. Consequently, the intensity of incident light passing through the liquid crystal also changes. Liquid crystal displays utilize the optical activity of the liquid crystal material combined with electric field control to achieve information display. 8. Backlight module: LCD products are non-emissive electronic devices that do not possess inherent light-emitting properties. They must rely on 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 liquid crystal panel. The backlight module includes illumination sources, reflectors, light guide plates, diffusion sheets, brightness enhancement films (prism sheets), and frames. Backlight modules used in LCD can be mainly divided into two categories: edge-lit backlight modules and direct-lit backlight modules. Mobile phones, laptops, and monitors (15 inches) primarily use edge-lit backlight modules, while LCD televisions mostly use direct-lit backlight module light 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 hood, mainly functions to direct all light emitted by the source into the light guide plate, minimizing useless loss as much as possible. 1. Light guide plate: The main function of the light guide plate is to guide light from the side light source to the front of the panel. 11. Prism sheet: Prism sheets, also known as brightness enhancement films, mainly function to concentrate scattered light through refraction and total reflection within the film layer, emitting it from the backlight source at specific angles to enhance screen brightness.13. Diffusion sheet: The main function of the diffusion sheet is to correct the edge-lit light from the backlight module into a uniform surface light source to achieve optical diffusion. Diffusion sheets are categorized into upper and lower diffusion sheets. The upper diffusion sheet is located between the prism sheet and the liquid crystal assembly, closer to the display panel. The lower diffusion sheet is located between the light guide plate and the prism sheet, closer to the light source.
