TFT-LCD liquid crystal displays or LCD monitors have become a popular choice for a wide range of applications. However, LCD monitors can be divided into two categories: industrial and consumer. While both types of monitors offer excellent display quality, their designs differ. Industrial LCD monitors are often deployed in places such as factories, outdoor kiosks, digital signage, military and naval applications, food processing, and hospitals. On the other hand, consumer monitors are usually used in office and home environments.

with a resolution of 1200*1920, a MIPI interface vertical screen, a brightness of 1500 lumens, which is clearly visible under strong outdoor light, and a contrast ratio of 1200.

How to choose between amorphous silicon (a-Si) and low temperature polysilicon (LTPS) for project development with display

LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.

First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.
