- OLED Displays: Organic Light Emitting Diodes (OLED) are a newer technology where each pixel emits its own light, allowing for deeper blacks and better contrast. This self-emissive nature of OLED technology leads to stunning picture quality, making it favored for high-end televisions and smartphones.
- MicroLED Displays: These are made up of microscopic LEDs that provide exceptional brightness and color accuracy, often used in high-end applications. MicroLED technology promises to combine the best features of both OLED and traditional LED displays, offering high brightness levels without the risk of burn-in that can affect OLED screens.
In addition to these types, there are also specialized LED displays designed for unique environments, such as outdoor billboards and digital signage. These displays are engineered to withstand various weather conditions and often feature enhanced brightness to ensure visibility in direct sunlight. Moreover, advancements in flexible LED technology are paving the way for innovative applications, allowing displays to be curved or shaped to fit unconventional spaces, further expanding the possibilities of LED technology in design and architecture.
