Low-voltage differential signaling, or LVDS, also known as TIA/EIA-644, is a technical standard that specifies electrical characteristics of a differential, serial signaling standard, but it is not a protocol. LVDS operates at low power and can run at very high speeds using inexpensive twisted-pair copper cables. LVDS is a physical layer specification only; many data communication standards and applications use it and add a data link layer as defined in the OSI model on top of it.
The liquid crystal display is a passive display. It cannot emit light and can only use the light of the surrounding environment. It only needs a small amount of energy to display patterns or characters. It is precisely because of low power consumption and miniaturization that LCD becomes a better display method. The liquid […]
The resistance of the conductor to the current is called the resistance of the conductor. Resistance (Resistor, usually represented by “R”) is a physical quantity that in physics represents the size of the conductor’s hindrance to current. The greater the resistance of the conductor, the greater the resistance of the conductor to the current. Different […]
1 Introduction In recent years, with the development of technology, the technology of thin film transistor (TFT) has been continuously developed and optimized, and the thin film transistor liquid crystal display (TFT-LCD) has quickly become the mainstream display screen in the market. However, TFT-LCD displays still have many problems, such as screen flicker which can […]
To learn embedded, you need to understand hardware knowledge, including single-chip microcomputer, ARM, FPGA, etc. Different hardware has different characteristics, and you need to understand their corresponding characteristics to be beneficial to operating applications. So what are the differences and characteristics of MCU, ARM, FPGA, and embedded? Features of MCU: 1. Due to […]
Analog chip Analog chips mainly include power management chips and signal chain chips. Among them, the power management chip is a chip that is responsible for the conversion, distribution, detection and other power management responsibilities of electric energy in the electronic equipment system. It is mainly divided into AC-DC AC-DC conversion, DC-DC DC and DC […]
IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor), and has MOSFET The advantages of both the high input impedance and the low turn-on voltage drop of the GTR. The GTR saturation voltage is […]
Insulated Gate Bipolar Transistor (IGBT), also known as insulated gate transistor. Because it has a parasitic thyristor inside the IGBT, it can also be called an insulated gate thyristor. It is a new type of composite device developed in the mid-1980s. Because it combines the advantages of MOSFET and GTR, it has the advantages of […]
IGBT/power device The IGBT module is a modular semiconductor product that is packaged by IGBT (Insulated Gate Bipolar Transistor Chip) and FWD (Freewheeling Diode Chip) through a specific circuit bridge; the packaged IGBT module is directly applied to the inverter and the UPS is uninterrupted. Power supply and other equipment; IGBT module has the […]
Amplifier task is to amplify the weak electrical signal from the signal source (from the mixer in the professional audio system) to drive the speaker to produce sound. It can also refer to other devices that perform power amplification. The function of the power amplifier is to amplify the weak signal from the sound source […]
