The color change is so fast that the human eye perceives the separate colors as a single color frame. This technique is commonly used in projectors and some specialized displays to improve color accuracy and brightness.
Field Sequential Color (FSC) is a display technology used in various modern devices such as projectors, XR devices and special displays.
How Field Sequential Color works
- Basic principles: Field Sequential Color is based on the rapid sequencing of primary colors. Instead of mixing the colors simultaneously as in conventional displays, FSC displays them one after the other. Each color frame changes so quickly that the human eye perceives the colors as a single image.
- Technological implementation: In practice, this is achieved by fast refresh rates and precise color switching mechanisms. Projectors using this technology often have special light sources and color filters that allow colors to be projected in rapid succession. This method can significantly improve the color accuracy and brightness of the displayed image.
Advantages of Field Sequential Color
- Improved color accuracy: One of the main benefits of FSC is improved color accuracy. Because colors are not mixed through physical pixel patterns as in conventional displays, FSC displays can provide clearer and more accurate color reproduction. This is particularly important for applications that require high color fidelity, such as medical imaging or professional photography.
- Higher brightness: Another benefit is higher brightness. Because each color is projected separately and fully, the resulting image can be brighter than with conventional mixing techniques. This makes FSC ideal for environments where strong lighting is required, such as presentation rooms or cinemas.
Applications for Field Sequential Color
- Projectors: One of the most common applications of FSC is in projectors. These devices use the technology to project sharp and bright images that are easy to see in both small and large spaces.
- Specialized displays: In addition to projectors, FSC is also used in specialized displays used in areas such as medical imaging, professional photography and research.
Augmented Reality
Field Sequential Color (FSC) is used in Augmented Reality (AR) to make the display of virtual content more accurate and color true.
Advantages of FSC in Augmented Reality:
- Improved color accuracy: FSC enables more accurate color reproduction,
which is important for integrating virtual objects more realistically into the real world. - Increased brightness: The technology can increase the brightness of virtual content, which is particularly beneficial in bright environments.
- Lower pixel density requirements: Because colors are projected sequentially, the need for high pixel densities can be reduced, enabling the development of lighter and more efficient AR devices.
Overall, FSC helps improve the quality of the AR experience by making virtual content more vivid and realistic.
