How much do you know about the core technology of flexible screens?

In today’s rapidly developing modern technology, flexible screens, as an emerging technology, are changing our way of life. It can not only achieve the functions of traditional rigid screens, but also bring users a brand new experience with its unique flexibility and flexibility. This article will take you to explore the core technology of flexible screens and uncover their mysterious veil. Firstly, we need to understand what a flexible screen is. Simply put, a flexible screen refers to a display screen manufactured using special materials and technologies that have a certain degree of bending and folding ability. Compared with traditional rigid screens, flexible screens can better adapt to product designs of different shapes and reduce the weight and thickness of the equipment while ensuring functionality. So, what are the core technologies of flexible screens? Here are some key points: substrate material: Although traditional glass substrates are hard and durable, they limit the plasticity of the screen. To achieve flexibility, manufacturers usually choose to use plastic or polymers as substrate materials. These materials not only make the screen lightweight and easy to bend, but also have better impact resistance. OLED (Organic Light Emitting Diode) technology: OLED is currently one of the mainstream display technologies and is also the technology used by most flexible screens. OLED can emit light on its own without the need for a backlight board, making the screen thinner and lower in power consumption. In addition, as each pixel can be independently controlled on/off, OLED screens also have features such as wide viewing angle and high contrast. TFT (Thin Film Transistor) Backboard: TFT is an electronic component array used to drive liquid crystal displays (LCDs) and AMOLED (Active Matrix OLEDs). In flexible screens, TFT needs to meet higher requirements to support bending characteristics. At present, researchers are committed to developing new flexible TFT materials, such as metal oxide semiconductors. Packaging technology: In order to protect sensitive internal components from external environmental influences, flexible screens require reliable packaging solutions. Common packaging methods include using transparent adhesive, special coatings, or multi-layer film structures. These technologies not only improve the waterproof and dustproof performance of the screen, but also enhance its durability. Touch technology: Touch screens are an indispensable part of many mobile devices, and flexible screens also require matching touch solutions. Capacitive touch screen is currently the most common type, which achieves touch operation by detecting changes in charge caused by fingers. With the advancement of technology, there may be more new touch technologies based on nanomaterials or other innovative principles in the future. Surface fitting technology: In addition to achieving flexibility, it is also a challenge to perfectly fit the screen onto various irregular surfaces. This involves innovation in surface fitting technology and process flow. For example, Samsung’s Galaxy Z Fold series phones adopt advanced curved fitting technology, achieving almost seamless folding effects. Production process: Finally, the production process of flexible screens is also crucial. From material procurement and processing to the assembly of the final product, every step requires precise control and strict quality management. For example, roll to roll printing technology can greatly reduce costs and improve efficiency, thereby accelerating the large-scale application of flexible screens. The core technology of flexible screens covers multiple fields such as materials science, physics, chemistry, etc. Their continuous development and improvement have promoted the popularization of this revolutionary technology. In the future, we can foresee the emergence of flexible screens in more products, bringing us a more diverse and personalized selection of consumer electronics products.
