Abstract
The integrated imaging stereoscopic display technology is an image technology that uses a microlens array to record and display 3D spatial scene information. The research of integrated imaging LED display technology provides a new development path for the LED industry. In this paper, we use micro lens array to perform stereoscopic display experiments on LED display screens with a dot pitch of 1.25mm. It is found that there is a phenomenon of dispersion of light (rainbow phenomenon) due to crosstalk. Especially when a white light source is displayed, crosstalk is the most serious. In order to solve this problem, according to the relationship between the light emission characteristics of the LED point light source and the crosstalk degree of the LED display pixel point after the lens, a barrier lens is designed to effectively solve the light dispersion phenomenon.
