AI Technical Summary

Benefits of technology

This technology allows people who want to create better ways to show things they see without having them shut off from their surroundings by controlling how much light falls down onto these surfaces instead of just allowing it upwardly like rainwater. Additionally, this technology could help families work together smoothly during housekeeping activities while still maintaining good appearance.

Problems solved by technology

The technical problem addressed in this patented text relates how current displays on TV monitors have limitations that make it difficult for users who watch them overtime lose their focus due to eye strain caused by having too much light behind us. This phenomenon occurs because traditional methods like displaying images with colored lights require certain angles between each pixel before they start moving downward towards the viewer.

Abstract

The invention discloses a control device for displaying a water curtain image based on a black and white picture. The control device comprises a water drop generator retainer, water drop generators, a water injection pipeline and a computer controller. The water drop generators are arranged on the water drop generator retainer side by side. A water outlet of the water injection pipeline is communicated with water inlets of the water drop generators. Controlled switches of the water drop generators are connected with the computer controller. The number of the water drop generators is the same as that of the subregions which are obtained by segmenting an image to be displayed according to transverse strips and segmenting each strip in the longitudinal direction. The computer controller comprises an image segmentation module and a water curtain imaging control module. The image segmentation module is used for segmenting the black and white picture to be displayed according to transverse strips from the bottom of the picture, and segmenting each strip in the longitudinal direction into subregions. The water curtain imaging control module is used for controlling the state of the controlled switches of the water drop generators by judging the pixel values of the centers of the subregions obtained after each transverse strip is segmented. The control device is low in cost, easy to operate and control, novel in form and good in man-machine interaction.
