As you may already be aware, there are various varieties of flexible digital display types on the market, all of which may be specifically created to carry out specific functions and are appropriate for a variety of industrial, commercial, and personal needs.The LCD panel of an LCD monitor determines whether it is good or bad. Since the LCD panel makes up more than half of the price of the entire device and is therefore the main factor influencing the cost of LCD monitors, selecting the LCD panel is the first step in selecting a good LCD monitor. What are the factors that affect the LCD panel? The LCD panel can greatly influence the brightness, contrast, color, viewing angle, and other highly essential LCD features. What types of LCD panels can you divide into? Discuss it together as a group!
The three following LCD panel types—TN, VA, and IPS—occupy the three primary positions in the market today. They each employ various liquid crystal materials and panel architectures, as well as their own benefits and drawbacks. Here, we go into great detail on the variations between TN TFT and IPS TFT.
using TN technology Twisted Nematic is frequently used in budget LCD monitors because of its inexpensive price, which is its best characteristic. A 19-inch widescreen LCD monitor is currently available for purchase; it exclusively uses TN panels.
One of the reasons why manufacturers prefer the TN panel is that it is not only less expensive but also has a quicker response time.
Although the panel is inexpensive, the response time is also quick, but there are also flaws such as a lack of display color, a narrow viewing angle, and others.
Although there are enhanced TN panels on the market that can display 16.7M colors or add an 8bit driver, the TN panel can only actually display 16.2M colors naturally. As a result, the effect of 16.7M color displays cannot be compared to 16.7M color displays physically.
Furthermore, the early TN panel technology's maximum viewing angle was just 90 degrees; however, this was eventually increased by adding a layer of compensating film to the panel (TN+film panels are now the most popular LCDs on the market).
Faster response time is another factor that makes TN panels popular among manufacturers. - Low cost, often utilized in low-end LCD monitors.
Only 16.2M of color was displayed, which is insufficient. With a later-improved TN panel or the addition of an 8-bit driver, 16.7M of color may be displayed.
The main distinction between IPS and TFT LCDs is bad viewing angle.
Contrary to other LCD models, which have electrodes arrayed in three dimensions on the top and bottom, in-plane switching (IPS) technology has its two poles on the same surface. The liquid crystal molecules are constantly parallel to the screen, regardless of the state they are in, which lowers the opening rate, lowers light transmission, and improves viewing angles. This is because the electrodes are all on the same plane.
IPS TFT panels have a response time of about 0.3 milliseconds, while TN TFT screens have a response time of about 10 milliseconds, making the latter inappropriate for gaming. Wide viewing angles, even full viewing angles. High contrast.
- Accurate replication of color. To get superior black, you must rely on the optical film compensation since the light leakage issue is more serious and the black purity is only slightly better than PVA.
The display screen is not the same, and one of the greatest differences between TN TFT and IPS TFT, which typically belong to a type of TFT-LCD, is the display angle. Can it be argued that IPS is superior to TN because the IPS display angle is better? Depending on our needs for him, the option of TN or IPS may not always be the answer.
Imagine you are an aviation mechanic. It might be really uncomfortable if the person sitting next to you is constantly glancing at their screen. There are pricier methods available to intentionally reduce the viewing angle.
To make our lives more convenient, display producers should also select various displays in accordance with consumer preferences.
