Abstract
The invention discloses an LED display screen which comprises a bottom shell, a panel, a PBC, a light isolation plate and an optical lens, the bottom shell comprises a bottom plate and side plates surrounding the periphery of the bottom plate, a first mounting column, a second mounting column and a grid protruding structure are arranged on the front face of the bottom plate, and the first mountingcolumn is higher than the grid protruding structure. Bottom plate bosses are arranged on the inner side walls of the side plates. The optical lens comprises a lens substrate, a lens group and a lenspositioning column, the lens group comprises a light emitting part and a light guide column, the light emitting part is arranged on the front surface of the lens substrate, and the positioning columnand the light guide column are arranged on the back surface of the lens substrate. The LED display screen is high in matching precision, good in sealing performance and good in heat dissipation effect, and has good display effect consistency and stability.
Description
technical field [0001] The invention relates to the technical field of LED display screens, in particular to LED display screens. Background technique [0002] LED display has the advantages of high brightness, splicing, convenience and flexibility, high efficiency and low consumption, etc., which makes it widely used in large-area display, especially in sports, advertising, finance, exhibition, transportation and other fields. [0003] Due to the small viewing angle of the existing LED display, it is necessary to install a lens above the light source, and how to achieve a sealed connection between the lens, the light barrier, the PCB board and the bottom case is a technical problem that needs to be solved for the existing LED display. [0004] In addition, in addition to forming a tight connection between the bottom case, PCB board, light barrier and lens to reduce the overall thickness of the LED display, it is also necessary to improve the overall heat dissipation effect ...
