LED film display is a kind of display technology that uses thin film transistor (TFT) technology to manufacture LED arrays on a flexible substrate, so that the display can be bent and curved. It is widely used in various curved display screens, including curved TVs, curved monitors, curved advertising screens, etc.

Compared with traditional display technologies, LED film display has the following advantages: First, it has a high brightness, which can reach hundreds of thousands of nits, and can achieve very good daylight readability. Second, it has a high contrast, which can reach 5000:1 or even higher, and can greatly improve the color gamut and color temperature control ability of the display. Third, it has a wide viewing angle, which can achieve ±88 degrees viewing angle, and can meet the needs of different viewers. Fourth, it has a very small thickness, which can be less than 1mm, and can greatly reduce the volume and weight of the display. Fifth, it has a high flexibility, which can be bent and curved according to the needs of the application environment, and can greatly improve the design space and flexibility of the display.

However, LED film display also has some challenges and problems. First, because the LED film display uses flexible substrate, its production cost is relatively high, and it needs to be continuously improved to reduce the cost. Second, because the LED film display needs to be bent and curved according to the needs of the application environment, its production process is more complex than that of traditional flat panel display, and needs to be continuously improved. Third, because the LED film display needs to be bent and curved according to the needs of the application environment, its mechanical strength is relatively low, and needs to be improved.

In summary, LED film display is a kind of advanced display technology that uses thin film transistor technology to manufacture LED arrays on a flexible substrate. It has many advantages in brightness, contrast, viewing angle, thickness and flexibility. It will replace traditional flat panel display technology and become a new generation of leading display technology.
