In modern industry, automobile, consumer electronics and other fields, liquid crystal display (LCD) has long been an indispensable core component. From the monitoring panel of power equipment to the instrument display screen of automobile, from the dashboard of motorcycle to the operation interface of photovoltaic equipment, LCD is widely used in various industries with its advantages of stability, energy saving and clarity. However, for many buyers and practitioners, there are still many questions about the core principle, classification and applicable scenarios of LCD. Today, as a professional manufacturer who has been deeply involved in the field of LCD for 21 years, Future provides you with a comprehensive knowledge of popular science LCD, helps you quickly understand the core logic and classification characteristics of LCD, and provides reference for selection and procurement.
First of all, let’s clarify the core definition: LCD, which is called Liquid Crystal Display, it is a flat display device that uses the optical characteristics of liquid crystal to display images and characters by controlling the arrangement of liquid crystal molecules. Compared with the traditional CRT display, LCD has the advantages of small size, light weight, low power consumption, no radiation and clear display, and it is one of the most widely used display technologies in the world. Its core working principle is not complicated: the liquid crystal itself does not emit light, and it needs to rely on the backlight layer to provide the light source, and the rotation direction of liquid crystal molecules is controlled by electrodes to change the angle of light penetration and refraction, thus presenting different images and characters on the screen. Simply put, LCD is like a “light switch”. By controlling the arrangement of liquid crystal molecules, the light can be accurately controlled, and then the display function can be completed.
According to the arrangement and optical characteristics of liquid crystal molecules, LCDs are mainly divided into these categories: TN LCD, VA LCD, STN LCD and FSTN LCD, among which TN and VA are the most commonly used types in industry, vehicle and other fields, and are also the core advantage products of Feiyoute.
1、TN LCD(Twisted Nematic LCD). This is the most basic and commonly used LCD type, and it is also the most widely used product in the industrial field at present. Its core advantages are fast response (usually 1-5ms), low power consumption, controllable cost, and good stability, which can adapt to the harsh requirements of industrial scenes. The disadvantage of TN LCD is that the viewing angle is relatively narrow, and color distortion will appear when viewed at a large angle, but it can fully meet the needs for most application scenarios with a single viewing angle such as industrial monitoring and power meters. Feiyoute has been deeply involved in the field of TN LCD for 21 years, mastered the core technology, and achieved 99.5% industry-leading yield on the new intelligent production line, providing stable and cost-effective TN LCD products for electric power, industrial control and other fields.
2、 VA LCD(Vertical Alignment LCD). The core advantages of VA LCD are ultra-high contrast ratio (usually more than 3000:1), high color reproduction and wide viewing angle, which can keep clear display effect at different angles, and it is suitable for scenes that require high display quality, such as automobile instruments, photovoltaic monitoring and high-end industrial control equipment. Compared with TN LCD, the response speed of VA LCD is a little slower, but with the continuous optimization of technology, it has been able to meet the needs of most vehicle and industrial scenes. The yield of VA LCD products of Feiyoute reaches 98%. Through process optimization, the stability and response speed of products are further improved while maintaining high contrast, which meets the requirements of high-end vertical fields.
3、STN LCD(Super Twisted Nematic LCD), a super twisted nematic liquid crystal display, is an upgraded version of TN LCD. By optimizing the twist angle of liquid crystal molecules, the contrast and viewing angle are improved, which has the characteristics of low power consumption and high stability. It has a wide range of uses, and its core is suitable for industrial instruments, power control panels, portable devices, low-end vehicle-mounted auxiliary displays and other scenes. Feiyoute can provide customized STN LCD products to adapt to harsh working conditions in many industries.
4、 FSTN LCD (Film Super Twisted Nematic LCD), is an enhanced version of twisted nematic (TN)LCD, which solves the problem of narrow viewing angle and low contrast of TN screen by optimizing viewing angle and contrast through compensation film, and has the advantages of low power consumption and high stability of TN screen. It has a wide range of uses, and its core is suitable for industrial instruments, power equipment, vehicle-mounted auxiliary display and other scenes. Feiyoute can provide customized FSTN LCD products to meet the requirements of severe working conditions.
As a national high-tech enterprise with 21 years of LCD manufacturing experience, Feiyoute focuses on the research, development, production and customization of TN and VA LCD, and provides customized LCD solutions for various industries with perfect research and development system, strict quality control and advanced intelligent production lines. Whether it is a basic TN LCD product or a high-end VA LCD product, Feiyoute can meet the diversified needs of customers with high yield and high stability, and help customers improve their product competitiveness.
