Seamless displaying method of LED color screen and black-and-white transmitting liquid crystal display

Abstract

The invention belongs to the field of television displaying, and particularly relates to a seamless displaying method of an LED color screen and a black-and-white transmitting liquid crystal display.The seamless displaying method of the LED color screen and the black-and-white transmitting liquid crystal display is characterized in that the LED color screen is arranged inside, the black-and-whitetransmitting liquid crystal display is arranged outside, and the LED color screen outputs image light information after passing through a screen hood of the black-and-white transmitting liquid crystal display. The seamless displaying method has the advantages that as for pixel images which are subjected to filtering treatment by the black-and-white transmitting liquid crystal display, although partial luminance of a color screen pixel unit circular cone range is filtered out, a network black area among color screen pixels is illuminated, and full play is given to the advantages of the surface-mounted LED display screen of being wide in viewing angle, good in light mixing and light distributing, vivid in color and high in contrast ratio, and seamless and flawless displaying of images output by the LED color screen is achieved. As is founded by experiments, after filtering, the light transmitting rate is lowered compared with that of original plastics film, however, the images are new and have third dimension, and are beautiful, distinct and vivid, and thus the LED color screen is likely to be a high-definition television.

Description

technical field [0001] The invention belongs to the field of television display, and in particular relates to a seamless display method of an LED color screen plus a black and white transmissive liquid crystal screen. Background technique [0002] This invention is developed on the basis of my invention patent - a plastic film laminated dot matrix LED color screen cover with partially transparent apertures (patent number 2016108795913). The unit pixels of the LED color screen are distributed at equal distances in the vertical and horizontal directions. This vertical and horizontal equidistant distribution is called dot matrix distribution; the equidistant name is called pixel period P. The unit of the pixel period P is mm, such as P2, P2.5, P3, P4, and the distribution represents the pixel period A=2, 2.5, 3, 4 mm. In a pixel cycle, there is only one full-color pixel chip in the center. The full-color pixel chips need to be insulated from each other, and the pixel chips ar...
