What are the characteristics of TFT LCD module

<p>The <a href="https://www.genyulcm.com/tft-lcd-module" rel="noopener noreferrer" target="_blank">TFT lcd module</a> means that each liquid crystal pixel on the liquid crystal display screen is driven by a thin film transistor integrated behind it. Thus, high-speed, high-brightness and high-contrast display information can be achieved. Each pixel of the medical TFT LCD device is controlled by the TFT integrated on itself, and it is an active pixel. Therefore, not only the speed can be greatly improved, but also the contrast and brightness are greatly improved, and the resolution has reached a very high level.</p><p><br></p><p>Technical characteristics of TFT lcd module:</p><p>TFT technology was developed in the 1990s. It adopts new materials and new processes for large-scale semiconductor full integrated circuit manufacturing technology. It is a liquid crystal (LC), inorganic and organic thin film electroluminescence (EL and OEL) flat panel display. Foundation. Its main features are:</p><p><br></p><p>1. Large area: The first generation of large-area glass substrate (300mm×400mm) TFT-LCD production line was put into operation in the early 1990s. By the first half of 2000, the area of the glass substrate had been expanded to 680mm×880mm), and recently 950mm×1200mm glass The substrate will also be put into operation.</p><p><br></p><p>2. Powerful function: TFT is the earliest matrix addressing circuit to improve the liquid crystal light valve characteristics. For high-resolution display screens, through the voltage adjustment in the range of 0-6V (its typical value is 0.2 to 4V), the precise control of the object element is realized, thereby enabling the LCD to achieve high-quality high-resolution display.</p><p><br></p><p>3. Low cost: The glass substrate and the plastic substrate fundamentally solve the cost problem of large-scale semiconductor integrated circuits, and open up a broad application space for the application of large-scale semiconductor integrated circuits.</p><p><br></p><p>4. Flexible process: In addition to using traditional processes such as sputtering, CVD (Chemical Vapor Deposition) and MCVD (Molecular Chemical Vapor Deposition), laser annealing technology has also begun to be applied. It can be used to make amorphous or polycrystalline films. Manufacturing single crystal film. Not only can the silicon film be made, but also other II-VI and III-V semiconductor thin films can be made.</p><p><br></p><p>5. A wide range of applications, LCD flat panel display based on medical TFT LCD device technology is the pillar industry of the information society, and its technology can be applied to the rapidly growing thin film transistor organic electroluminescence (TFT-OLED) flat panel display The screen is also growing rapidly.</p><p><br></p><p><br></p><p>Functional characteristics of TFT:</p><p>With the maturity of TFT technology in the early 1990s, the color LCD flat panel display has developed rapidly. In less than 10 years, TFT-LCD has rapidly grown into a mainstream display, which is inseparable from its advantages. The main features are:</p><p><br></p><p>1. Good use characteristics: low voltage application, low driving voltage, solidified use safety and reliability improvement; flat, light and thin, saving a lot of raw materials and use space; low power consumption, its power consumption is about CRT display One-tenth, reflective TFT-LCD is only about one percent of CRT, saving a lot of energy; TFT-LCD products also have specifications, models and sizes in series, variety, convenient and flexible use, maintenance and update , Easy upgrade, long service life and many other features.</p><p><br></p><p>2. Good environmental protection characteristics: no radiation, no flicker, no harm to the user's health. In particular, the emergence of TFT-LCD electronic books and periodicals will bring human beings into the era of paperless office and paperless printing.</p><p><br></p>
