CRT televisions demonstrate longer lifespans than modern LCD and LED models

Research indicates that older cathode ray tube (CRT) televisions generally possess a longer lifespan than modern LCD and LED models. A study published in the journal Waste Management, based on data from discarded televisions in Sweden, found that CRT TVs had an average and median lifespan of approximately 15 years. In contrast, modern LCD and LED televisions averaged about six years of use.

The study noted that over 40% of LCD/LED televisions were discarded within their first five years, compared to roughly 20% of CRT models. While some early disposals may be due to consumer preference for larger screens or newer features rather than mechanical failure, several technical factors contribute to the longevity of older units.

CRTs are primarily analog devices with relatively simple circuitry, whereas modern Smart TVs integrate complex hardware including processors, memory, and network connectivity. This increased complexity introduces more potential points of failure. Additionally, modern flat panels often generate significant heat within confined spaces, which can accelerate component aging. Software also plays a critical role; modern TVs face obsolescence when applications lose support or software updates are no longer provided, even if the physical hardware remains functional.
