Recently, many customers have been asking about the differences between LED and LCD displays. Why do you always recommend that we use LED screens? Today, let’s introduce the differences between LED and LCD. LCD Splicing Screen LED Display Screen Screen Composition: LCD is a display screen composed of liquid crystals; LED is a display screen … Read more
In January of this year, most regions in China experienced severe cold weather. Some jokingly said they could run benchmarks on their phones to keep warm, reflecting a deeply rooted issue in people’s minds regarding phone heat generation. As the core of the mobile phone, the CPU largely represents the phone’s performance. From the initial … Read more

Click the blue WeChat name below the title to quickly follow With the continuous development of process nodes (now commonly at 28nm, 22nm, 16nm, 14nm, and even some at 7nm), the performance demands of chips are increasing, and their scale is growing larger. Digital IC design engineers are becoming increasingly concerned about chip power consumption, … Read more
After years of low-power hardware design (the hardware and software design in the company are separate, and I have always been doing hardware. Facing low-power production issues in hardware can often be quite challenging), I found that one common issue is that the IO is not configured properly before the microcontroller enters sleep mode. The … Read more
Looking at today’s applications, whether in the Internet of Things, consumer mobile devices, or various devices that can connect to wall outlets, including servers, low power consumption has become a differentiating factor and a necessary condition for product success (as noted by techsugar). Written by: Brian Bailey Translated by: Editorial Team Advancements in mobile technology … Read more
In the early stages of IC design, the main parameters of concern were performance (timing) and area. EDA tools minimized area while meeting performance requirements. At this time, power consumption was not a major concern. Because CMOS technology exhibits relatively low power consumption at lower clock frequencies, leakage current can be negligible. However, as transistor … Read more
