TFT panel is the core component of the display, mainly composed of thin-film transistor TFT (Thin-Film Transistor) panel and polarizer backlight, etc. Its durability depends on the TFT panel and TFT backlight:
1. TFT LCD panel
1.Material properties: the life of the TFT panel is mainly determined by the stability of the material, usually the life of the panel itself can be more than 10 years, and will not be easily damaged because of the use of too long.
2.No physical wear and tear: because the liquid crystal itself is a static material, under normal circumstances it will not be like mechanical parts as a result of physical wear and tear and failure.
3.Polarizer Aging: Over time, polarizers may gradually age, resulting in decreased screen contrast and color deviations.
4.Temperature range: Normal TFT panels usually operate at temperatures between -20°C and 70°C. High and low temperature conditions accelerate aging, and humidity is higher than 85% RH, but they have a longer lifespan in normal environments.
2. TFT LCD backlight
The backlight is the part of the TFT display responsible for providing the light source. Backlight brightness life and durability depend on the performance of the LEDs.
1.LED Lifespan: Normal LED backlighting is rated for 30,000 to 50,000 hours (i.e., 8 hours of use per day for 10-15 years). Industrial grade LED backlights can reach 70,000 hours or more.
2. Brightness Decay: LEDs will gradually experience light decay during use, i.e., the brightness slowly decreases. When the light fades to 50% of the original brightness, it is usually considered as the end of the life of the backlight.
3.Excessive current: If the backlight driver circuit provides excessive current for a long period of time, it will lead to accelerated aging of the LED.
4.Voltage fluctuation: Unstable power supply environment may cause the backlight life to be shortened or even burn out the LED light source.
5.If the backlight decreases in brightness due to aging or damage, the backlight module can be replaced individually without replacing the entire screen, reducing maintenance costs.
Summary: Overall durability of TFT
1. TFT panel:
Normal service life is more than 10 years, high durability and better environmental adaptability.
2. TFT backlight:
Normal service life is more than 10 years, mainly affected by brightness reduction.
