In different use occasions, the requirements of the visual resolution of the LED display screen of the all-in-one machine are met, the display effect and the visual quality are ensured, the matching and the selection of the lens module array are required to be fully considered, and the influence of the target viewing distance and the visual angle on the visual resolution is required to be met.
The lens element generally refers to a single lens in a lens system, the lens module is an optical element capable of focusing or scattering light to change the propagation direction and characteristics of the light, a plurality of lens elements with the same optical characteristics and physical dimensions form the lens module, and a plurality of lens modules are arranged in an array to form a display screen.
The lens module of the LED display screen of the all-in-one machine is used for determining the shape of the lens element and the lens material according to the pixel density, the visual distance and the visual angle of a specific display screen, so that the light is ensured to be projected to the correct position. For the LED display screen of the all-in-one machine, a narrower light beam is usually required to avoid overlapping and diffusion of light rays, and meanwhile, uniform distribution of the light rays is ensured to avoid uneven brightness or shadows on the LED display screen of the all-in-one machine. The diameter of the lens element is related to the resolution, the visual angle and the coverage pixel number of the LED display screen of the all-in-one machine, when the aperture of the lens element is increased, the resolution of an image is reduced, the visual angle is increased, and the number of pixels contained in the lens element is increased; on the contrary, when the aperture of the lens element is increased, the resolution of the image is increased, the viewing angle is reduced, the viewing effect is improved, and the number of pixels contained in the lens element is increased. On the other hand, the focal length of the lens element determines the image depth of the LED display screen of the all-in-one machine, when the focal length of the lens element is increased, the viewing distance can be increased, but the distance between the LED display screen of the all-in-one machine and the lens module is also increased, and thus, the pixels at the inner edge of the lens element can cause crosstalk to influence the viewing effect. Conversely, reducing the focal length of the lens element can greatly reduce crosstalk, but the viewing distance becomes smaller and dispersion occurs.
Therefore, parameters of the lens module of the LED display screen of the all-in-one machine are not independent, and have a mutual influence relationship, the LED display screen of the existing all-in-one machine adopts a fixed packaging mode of the LED module and the lens module, the optimal visual distance and visual angle after packaging are fixed, and a viewer is required to adapt to the display screen in order to obtain good appearance. The optical performance and the stability of the system are ensured through the separable LED display screen lens module, the visual requirements on the LED integrated machine display screen under the requirements of different visual distances and visual angles are met, and meanwhile, the system has the flexibility and maintainability.
