Embodiment Construction

[0089] The core point of the present invention is that when a plurality of light spots or light sources form an image array of light spot gaps, optical reduction is carried out through optical elements to reduce the size of the optical surface of the image after the light spots or light sources pass through the optical elements, and at the same time the light spots or The gap between the light sources passes through the optical elements, and the image light spots or the gaps between the light sources are also proportionally reduced. When the image light spots or the gaps between the light sources are small, the light spots themselves are also focused to increase the brightness of the light spot size. Reduced light point optical image, due to the diffusion effect of such light point optical image when it is imaged on an imaging component with a diffusion effect, such as a projection screen, the gap between adjacent luminous light points in the light point optical image is diffuse...

Abstract

The invention provides a method and a system for improving display effect of optical lattice images. Images consist of light spot arrays are reduced optically by a first optical element so as to generate a first optical image on a first imaging part with scattering effect, and until the space between light spots in the first optical image is less than or equal to the size of the light spot in an optical image, gaps do not exist between the light spots in the first optical image; and the first optical image is amplified optically by using a second optical element to form a second optical image of a light spot image on a second imaging part. By adopting the technique of the invention, the images after optical processing of the lattice images do not have lattice gaps when presented to people, thus, a smooth image feeling is provided to a viewer, the aim of improving the image display effect is achieved and further the image quality is improved. Simultaneously, the technique of the invention can also be used for designing new projection devices and illuminating systems.

Description

technical field [0001] The invention relates to a method and a system for improving the display effect of light dot matrix images, in particular to a method and a system for improving the display effect of LED images. Background technique [0002] LED lights, also known as solid-state light-emitting devices, can be made smaller because of their long service life, and their brightness can be controlled by controlling the current loaded on the LED lights, and the LED lights can have multiple colors. Therefore, LED lights are used as image display devices, which are widely used in large-screen advertising systems and large-screen TV receiving systems. [0003] However, because the LED lights need to be fixed on the circuit board to form an LED light array, there are gaps between the LED lights. When people watch the image displayed by the LED array at a relatively close distance, they will see obvious pixel interval areas, resulting in blurred images. Problem with low image qu...
