Review Questions

• How do Quantum Dots enhance the quality of display technology?
  • Quantum Dots enhance display technology by providing improved color accuracy and wider color gamuts. They emit specific wavelengths of light depending on their size, allowing for vibrant and precise color representation. This feature is particularly beneficial in applications like QD-LEDs, where Quantum Dots help achieve better brightness and contrast, leading to a superior viewing experience.
• Compare and contrast LCD and OLED technologies in terms of their advantages for display technology.
  • LCD technology offers advantages such as lower production costs and longevity, but it typically struggles with black levels due to reliance on backlighting. In contrast, OLED technology provides superior contrast ratios and deeper blacks because each pixel emits its own light. This allows OLED displays to deliver more vibrant colors and an overall richer visual experience, although they may come at a higher cost and have potential burn-in issues.
• Evaluate the future implications of advancements in display technology for industries beyond consumer electronics.
  • Advancements in display technology are set to significantly impact various industries beyond consumer electronics, including medical imaging, automotive displays, and advertising. For instance, high-resolution displays with enhanced color accuracy can improve diagnostic tools in healthcare, while automotive heads-up displays can offer drivers real-time data with better visibility. Additionally, innovative display technologies like flexible screens could transform advertising by enabling new formats for digital signage that are more engaging and interactive.
