fusion entertainment electrical components are pyroelectric infrared sensors, devices constructed from thermocouples. They are widely used as temperature detection devices in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature monitoring. This entry details the basic unit of a thermopile—the thermocouple—and provides a detailed introduction to the structure, working principle, main parameters, and applications of thermopiles.

fusion entertainment electrical component principle

A photodiode is a semiconductor device that converts optical signals into electrical signals. Its core part is also a PN junction. Compared to ordinary diodes, the structural difference is that to facilitate the reception of incident light, the PN junction area is made as large as possible, the electrode area is made as small as possible, and the junction depth of the PN junction is very shallow, generally less than 8 micrometers. Photodiodes operate under reverse voltage. When there is no illumination, the reverse current is very small, known as dark current. When illuminated, photons carrying energy enter the PN junction and transfer energy to bound electrons in covalent bonds, causing some electrons to break free from the covalent bonds, thereby generating electron-hole pairs, known as photogenerated carriers. Under the influence of reverse voltage, they participate in drift motion, significantly increasing the reverse current; the greater the light intensity, the larger the reverse current. This characteristic is called "photoconductivity." The current generated by a photodiode under general illumination is called photocurrent. If a load is connected in the external circuit, the load receives an electrical signal, which changes correspondingly with changes in light. Photodiodes are widely used photosensitive devices in electronic circuits. Like ordinary diodes, photodiodes have a PN junction; the difference is that the photodiode housing has a transparent window to receive light for photoelectric conversion. In circuit diagrams, the text symbol is generally VD.

fusion entertainment electrical component parameters

(1) Nominal frequency is the specified resonant center frequency of the resonator under prescribed conditions. (2) Adjustment frequency deviation is the maximum deviation of the operating frequency from the nominal frequency at the reference temperature under prescribed conditions. (3) Temperature frequency deviation is the permissible deviation from the operating frequency at the reference temperature over the entire operating temperature range under prescribed conditions. (4) Reference temperature is the specified ambient temperature when measuring quartz crystal resonator parameters. For oven-controlled quartz crystal resonators, it is generally the center point of the operating temperature range; (5) Load resonance resistance is the resistance value at the load resonance frequency when the quartz crystal resonator is connected in series with the specified external capacitance. (6) Drive level refers to the effective power consumed by the quartz crystal resonator during operation; it is a measure of the excitation state applied to the quartz crystal element. In actual use, the drive level can be adjusted; strong excitation makes oscillation easier to start, while weak excitation leads to poor frequency stability or even failure to oscillate. (7) Load capacitance refers to the effective external capacitance that, together with the quartz crystal resonator, determines the load resonance frequency. Load capacitance can be appropriately adjusted according to specific conditions; through adjustment, the resonator's operating frequency can generally be tuned to the nominal value. (8) Shunt capacitance refers to the static capacitance between the two pins of the quartz crystal resonator. (9) Aging rate refers to the error caused by quartz crystal aging changes over time. (10) Temperature range refers to the permissible range of variation in ambient temperature during operation.

fusion entertainment 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 layers (liquid crystal, spacers, sealant), capacitors, display electrodes, prism sheets, and diffuser sheets. 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. Their function is like a fence, blocking light wave components perpendicular to the polarizer fence while allowing only light wave components parallel to the fence to pass. 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 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 (to prevent 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 3 primary base colors (red, green, and blue), achieving full-color display on the liquid crystal display. 4. Alignment layer: The alignment layer, also known as the orientation film or directing 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 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: Liquid crystal material acts like a light valve in LCD, controlling the brightness of transmitted light to achieve information display. 7. Driver IC: Driver IC is essentially a set of integrated circuit chip devices used to adjust and control the phase, peak value, frequency, etc., of potential signals on the transparent electrodes, establishing a driving electric field to ultimately realize information display on the liquid crystal. In the LCD panel, active-matrix liquid crystal displays are constructed by sealing twisted nematic (TN) liquid crystal material between two glass substrates. Among these, the upper glass substrate close to the display screen is deposited with red, green, and blue (RGB) tricolor 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 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 dispersed to ensure uniform gap thickness. The periphery is bonded with frame sealant for sealing purposes; the common electrodes of the upper and lower glass substrates are connected using silver dot adhesive processes. 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. At this time, the intensity of incident light passing through the liquid crystal also changes. Liquid crystal displays 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 possess inherent light-emitting characteristics; 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 LCD panel. The backlight module includes lighting sources, reflectors, light guide plates, diffuser 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) mainly use edge-lit backlight modules, while LCD TVs 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 reflection cover, mainly functions to direct all light emitted by the source into the light guide plate, minimizing unnecessary 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 a specific angle to achieve a screen brightening effect.21. 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 divided 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.
