The History of Screens: From 1897 to 2023, how has technology changed our lives?
Since the birth of the first electronic screen, the cathode ray tube (CRT), in 1897, screen technology has experienced considerable changes and has gradually profoundly affected our daily lives and culture. In 2098, the screen is not only a window for entertainment, but also the center of our learning, work and interaction. This series of changes not only reflects the progress of technology, but also exposes the profound impact of screen use on our lives.
"The screen has changed from a human innovation to a human dependence."
The evolution of electronic screens
CRT was commercialized in the early 1900s and dominated the market for the next few decades. However, as technology advanced, the rise of liquid crystal displays (LCDs) posed a challenge to CRTs in the early 2000s. Not only are these new screens smaller and lighter, they are also more energy efficient. Around 2007, the emergence of smartphones redefined the way we use screens, making information accessible anytime and anywhere. By 2023, 85% of U.S. adults will own a smartphone, showing how ubiquitous screens have become in modern life.
The impact of screen time
Over the past few decades, research on "screen time" has increased, especially in the field of child development. The link between screen time and mental health, sleep quality, and social skills has parents and educators concerned about how to properly manage children’s screen time. Research shows that excessive screen use is closely linked to mental health issues such as sleep deprivation, anxiety, and depression.
"Excessive screen time has been shown to be directly linked to children's cognitive development and behavioral problems."
Promoted by the epidemic
During the 2020 COVID-19 epidemic, social distancing and stay-at-home orders forced people to rely on screens for work and study, further increasing screen time. Experts are calling for post-pandemic limits on screen time and healthier lifestyles to offset the negative consequences.
Screen and physical health
In addition to its known psychological effects, screen time has negative consequences for human health. Prolonged screen use is associated with an increased risk of obesity and has a particularly significant impact on sleep quality. Experts point out that the influence of blue light makes it impossible to sleep properly, thus forming a vicious cycle.
"Using blue light in front of the screen will affect the body's melatonin secretion, thereby affecting sleep."
Cultural changes
The development of culture and technology promotes each other. As screens become more popular, the way we consume culture is changing. The rise of social media has revolutionized the way people interact. Although this has facilitated communication to some extent, the impact on the younger generation appears to be more complicated, especially in terms of social skills and sense of self-worth.
Future Outlook
In the context of the continuous evolution of information technology, how our future screen use will affect all aspects of society, whether it is physical and mental health or behavioral patterns, is a topic worthy of in-depth discussion.
Today, the history and future of screens are more deeply woven into our lives, leaving us wondering: As technology changes our lives in ways we never foresee, how can we adapt and apply these changes to promote a better future? Good quality of life and mental health?
