Daytime Running Lights and Interior Lighting

• LEDs are increasingly used in daytime running lights, providing enhanced visibility and a distinctive, modern look to the vehicle.
• LED interior lighting, such as ambient lighting, reading lights, and instrument panel illumination, offers a more sophisticated and customizable lighting experience for drivers and passengers.
• The energy efficiency and compact size of LEDs allow for the integration of these lighting features without significantly impacting the vehicle’s overall power consumption or design.

Display Technology: Illuminating the Digital World

LEDs have revolutionized the display industry, becoming the backbone of various display technologies that are ubiquitous in our everyday lives.

LCD Televisions

• LEDs are used as the backlight source in LCD (Liquid Crystal Display) televisions, providing a more energy-efficient and thinner display solution compared to traditional CCFL (Cold Cathode Fluorescent Lamp) backlighting.
• According to a report by Grand View Research, the global LED-backlit LCD TV market is expected to reach $131.8 billion by 2025, growing at a CAGR of 13.1% from 2018 to 2025.
• The use of LEDs in LCD TVs has enabled the development of larger screen sizes, higher contrast ratios, and improved color accuracy, enhancing the overall viewing experience.

Smartphones and Tablets

• LEDs are used in various components of smartphones and tablets, including backlighting for LCD screens, camera flash, and indicator lights.
• The global LED backlighting market for mobile devices is expected to grow from $2.6 billion in 2016 to $4.4 billion by 2023, at a CAGR of 7.6%, according to a report by MarketsandMarkets.
• The energy efficiency and compact size of LEDs have allowed for the integration of these features without significantly impacting the overall design and battery life of mobile devices.

Signage and Billboards

• LEDs are widely used in various signage and billboard applications, such as outdoor advertising, traffic signs, and scoreboards, providing high-brightness, energy-efficient, and long-lasting illumination.
• According to a report by Allied Market Research, the global LED signage market is expected to reach $14.2 billion by 2023, growing at a CAGR of 12.1% from 2017 to 2023.
• The versatility and programmability of LED-based signage and billboards allow for dynamic content display, enhanced visibility, and improved energy efficiency compared to traditional lighting solutions.
