Revolutionizing VR Display Resolution: The 2117 PPI 4K LCD Screen
Abstract
This work showcases the breakthrough achieved with the 2117 pixels per inch (PPI) Liquid Crystal Display (LCD) in developing high-resolution Virtual Reality (VR) displays. This technology significantly enhances the dynamic range and reduces the screen door effect of VR displays. The paper discusses the challenges and potential solutions in achieving LCDs with over 2000 PPI, including pixel aperture ratio design, LC efficiency improvements, and overall transmittance. Additionally, it proposes

Innovative Circuit Design: Create an Arduino Uno Without PCB Skills
Do you want to play with circuits but don't know how to design a PCB? You can! Before PCBs existed, components were connected directly (as imagined by Teacher Su). In fact, even when we have PCB design issues that require rework, we often use various jumper wires to make our circuits work.
So, even if your PCB design is flawless, occasionally DIYing a circuit without a PCB is also a meaningful endeavor.
Today, let's take a look at a project done by
Differences Between MCU and SoC
Understanding Microkernel Operating Systems and RTOS
The structure of the microkernel operating system developed in the late 1980s. Because it can effectively support multiprocessor operation, it is very suitable for distributed system environments.
Most of the currently popular operating systems that support multiprocessor operation have adopted the microkernel structure, such as the Mach OS developed by Carnegie Mellon University, which belongs to the microkernel structure operating system; and the widely
Performance Comparison of ARM Cortex-M Processors
1. Performance Metrics of Processors
There are many performance metrics used to evaluate CPUs, and the values obtained from different testing standards may vary based on the focus of the performance being tested. Below are two classic testing standards widely used in the embedded industry.
1.1 Dhrystone Standard
Dhrystone is a benchmark testing program proposed by Reinhold P. Weicker in 1984, primarily aimed at testing the performance of integer and logical operations of processors.
The Dhrystone program was initially released in Ada language, later

FisheyeMultiNet Real-time Multi-task Deep Learning Network for Surround View Autonomous Parking System
Background:
With advancements in deep learning and computer vision algorithms, autonomous driving has gained significant attention, and automatic parking is one of the application scenarios of autonomous driving. It is a low-speed, unorganized, and complex behavior that requires 360-degree near-field sensing of the vehicle's surroundings. The complexity of autonomous driving systems poses many limitations on hardware, prompting researchers to propose a
