What is AMOLED?25 April 2021
AMOLED is an active-matrix organic light-emitting diode. AMOLED is a display technology for mobile devices, digital cameras, media players, and television. It uses active matrices to address pixels and uses a special type of film technology, wherein the organic compound forms an electroluminescent material.
How Big is the DV/DT and DI/DT of the Power Device?24 April 2022
Hello everyone, I am Rose. Welcome to the new post today. This article describes how big the dv/dt and di/dt of high-speed power devices are?
Photocoupler Basis: Description, Applications and Working Principle29 September 2021
Hello, everyone. I am Rose. Welcome back to the new post today. Photocoupler is also known as optocoupler. To communicate electrical impulses, optocouplers employ light as a channel. It is frequently utilized in many circuits because it provides an excellent isolation effect on input and output electrical signals. After reading this article, you will have a clear understanding of Photocoupler.
Core Components behind Smart Glasses28 June 2023
Hello everyone, welcome to the new post today. We will explore what exactly smart glasses are and also go through the critical electronic components that drive the functionality of smart glasses.
An Overview of JFET19 August 2020
JFET is a Junction field-effect transistor. Regular transistor is a current-controlled device that requires biasing power, while JFET is a voltage-controlled device. The JFET is an active electronic component that is one of the electronics industry's workhorses that offers a reasonable compromise between cost and efficiency.
Stepper Motor: Types, Working and Applications26 December 2025
A brushless, synchronous electric motor that converts digital pulses to mechanical shaft rotation is known as a stepper motor. When operated by a sequentially switched DC power supply, the normal shaft motion is made up of discrete angular motions of approximately uniform magnitude.
Wireless Charging Explained: Working and Standards26 May 2021
Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method for charging mobile phones. High-power wireless charging often uses resonance (most electric vehicle charging uses this method) from the power supply equipment (charger) to transfer energy to the device that uses electricity.
How do We Select Automotive Relays?30 September 2020
A relay is an automatic control device whose output will have saltatory change when the input (electricity, magnetism, sound, light, heat) reaches a certain value. Automotive relays are relays used in automobiles. Such relays have high switching load power, high shock resistance and vibration resistance. Most power supplies in automobiles use 12V, and most of the coil voltages are designed to be 12V...
What are Types and Application of Gas Sensors?18 November 2025
The gas sensor is the core of the gas detection system and is usually installed in the detection head. Essentially, a gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. The probe uses the gas sensor to adjust the gas sample, which usually includes filtering out impurities and interfering gases, drying or refrigeration treatment, sample pump, and even chemical treatment of the sample, so that the chemical sensor can make faster measurements. In the following, we’ll mainly discuss the properties, typical types and application fields of gas sensors.
SAW Filter: Introduction, Features and Applications30 December 2020
The Surface Acoustic Wave (SAW) filter is a passive band-pass filter made by using the piezoelectric effect and the physical characteristics of surface acoustic wave propagation. Its role is to filter and delay electrical signals. It has the advantages of small size, stable performance, strong overload capacity, low phase distortion, and no need to adjust, so it is used in televisions, video recorders, wireless data transmission systems and other fields.
Network Interface Card: Types, Functions and Buying Guide17 August 2021
Network Interface Card (NIC, also known as a network interface controller) is one of the most basic components in the local area network. It is the hardware device connecting the computer and the network. Whether it is a twisted pair connection, a coaxial cable connection, or an optical fiber connection, data communication must be realized with the help of a network interface card.
What is a Fiber Optic Sensor?31 October 2025
Fiber optic sensor is a sensor that converts the state of the measured object into a measurable optical signal. The fiber optic sensor is to send the light beam incident from the light source to the modulator through the optical fiber, and interact with the external measured parameters in the modulator so that the optical properties of the light such as light intensity, wavelength, frequency, phase, polarization state, etc. will be changed.
