Apple AR / VR headset equipped with Micro-OLED screen, Samsung will push “holographic” AR devices to compete, sources say

According to ET News Korea, Apple’s AR / VR headset is once again rumored to feature an advanced Micro-OLED display. Micro-OLED displays are built directly on chip wafers rather than glass substrates, allowing for thinner, smaller, and more energy-efficient pixel sizes in the 4 to 20 micron range, compared to 40 to 300 microns for […]

What are the types of resistors? These three types must be understood

Classification by voltammetric characteristics For most conductors, at a certain temperature, their resistance remains almost constant and is a certain value, this type of resistance is called linear resistance. For some materials, the resistance varies significantly with current (or voltage), and the volt-ampere characteristic is a curve, which is called nonlinear resistance. The ratio of […]
