Displays used for AR (augmented reality) and VR (virtual reality) need to meet a series of specific requirements to ensure that users can get a high-quality, immersive visual experience. The following is a specific analysis of the requirements for AR/VR displays:
Importance: Resolution is a key factor in determining the clarity of the picture, which is particularly important for AR/VR devices, because low resolution may cause serious graininess in the picture, affecting the user's immersion and viewing experience.
Specific requirements: AR/VR displays usually need to achieve higher resolutions, such as 4K or higher, to provide delicate and clear pictures.
Importance: Brightness determines the visibility of the display in a strong light environment, which is particularly important for outdoor or indoor environments with strong light.
Specific requirements: AR/VR displays need to have high brightness to ensure a clear picture under various lighting conditions.
Importance: Contrast determines the difference in light and dark between the brightest and darkest parts of the display, which is crucial for picture details and color performance.
Specific requirements: AR/VR displays need to have high contrast to present rich colors and details. Micro OLED technology provides a contrast ratio of up to 100,000-1 million:1, which is better than display solutions such as Fast-LCD and Mini LED.
Importance: The refresh rate determines the number of times the display can update the screen per second, which is crucial to reducing screen delay and providing a smooth visual experience.
Specific requirements: AR/VR displays need to have a high refresh rate to reduce dizziness and delay when switching screens. Generally speaking, the refresh rate needs to be above 90 Hz to provide a smooth visual experience.
Importance: The field of view determines the range of screens that users can see, which is particularly important for the immersion of VR devices.
Specific requirements: AR/VR displays need to provide a wider field of view to ensure that users can get a full range of visual experience. Generally speaking, the field of view of VR devices needs to be greater than 90 degrees, while AR devices may vary depending on the specific application scenario.
Importance: The afterglow effect refers to the residual phenomenon of the previous frame after the screen switches, which may cause blurred images and dizziness.
Specific requirements: AR/VR displays need to have a low afterglow effect to reduce dizziness and discomfort when switching between screens. This usually requires the display to have a fast response time and low inter-frame delay.
Adaptability: AR/VR displays need to adapt to the pupil distance and vision requirements of different users to ensure that each user can get a clear picture. This is usually achieved through adjustable eye relief and pupil distance settings.
Comfort: AR/VR devices usually need to be worn for a long time, so the comfort and weight of the display are also important considerations. Lightweight design, comfortable wearing method and good heat dissipation performance are all key to improving user comfort.
Micro OLED: It is considered to be the best display solution for AR/VR at present because it has the advantages of higher pixel density (PPI), thinner and shorter, and less power consumption. However, the display material of Micro OLED is an organic material, which is sensitive to water and oxygen, resulting in a shorter device life.
Micro LED: Although it has higher brightness and life in theory, it is still in the laboratory research stage and faces difficulties such as brightness attenuation and mass transfer.
Fast-LCD and Mini LED: Both solutions are essentially LCD solutions, and both are passive luminescence and require a light source. The advantage of Mini LED over Fast-LCD is that more backlight partitions can be made to improve the contrast of the product. However, their power consumption is relatively high and the contrast is not as good as Micro OLED.
In summary, the display screen used for AR/VR needs to meet the requirements of high resolution, high brightness, high contrast, high refresh rate, wide field of view, low afterglow effect, and good adaptability and comfort. At the same time, the choice of technical solutions also needs to be weighed according to specific application scenarios and needs.
