In the rapidly advancing technology landscape, technologies such as 5G, IoT, and renewable energy have emerged like mushrooms after rain in recent years. Among them, display screens, as one of the most widely used applications, have also given rise to new display technologies, evolving from traditional LCD technology to the OLED technology of the past decade, and now to the trending MiniLED and MicroLED display technologies.What are the differences between these display technologies? Below, we will briefly explain.1. LCD TechnologyFirst, the traditional LCD technology relies on a backlight layer that only displays white light. However, there is a colored film on top of the backlight layer, which reflects a colored image to the eye.2. OLED TechnologyThe OLED technology has been around for nearly a decade and does not require backlighting, using millions of tiny, colored, self-emitting pixels that can be turned on or off individually. Compared to traditional LCDs, OLED screens provide more vivid colors, lower power consumption, and thinner screen thickness, offering a superior visual experience.3. MiniLED TechnologyMiniLED is currently a popular product. Mini LED refers to LED devices with chip sizes between 50-200μm. Previously, small-pitch LED chip sizes were generally greater than 200μm. Mini LED achieves a smaller size and uses direct backlight imaging, allowing for more micron-sized LED beads to fit into the backlight layer per unit area. The benefits include higher brightness, contrast, and precise light control.Moreover, as a major LED manufacturer, Everlight showcased MiniLED fish scale tail lights at the Shanghai Auto Show two years ago. The Mini tail lights were made using Everlight’s small-pitch display components, achieving a visual recognition density of 27.63 PPI, creating an excellent intelligent tail light system that can flexibly adjust displayed graphics and text according to needs, with overall image quality being exquisite and clear, meeting various functional requirements for tail lights. At that time, the Mini LED tail light concept product attracted many exterior lighting customers to continue discussions with Everlight.4. MicroLED TechnologyMicroLED is seen as the next generation of micro-display technology. Compared to current mainstream display technologies, it has many advantages, including high brightness, wide viewing angles, long lifespan, short response time, and low power consumption, as well as the characteristic of self-emission without the need for a backlight source, making it smaller and thinner, and highly futuristic. However, the technology is still not mature, making practical application challenging.In the era of large screens, TCL’s rise has showcased the innovative strength of Chinese enterprises to the world, making more domestic brands realize the necessity of having their core technologies in global market competition.PS: For sample testing, specification documents, application technology consulting, etc., regarding Everlight’s Mini series LED beads, please contact Chao Yi Electronics.
