Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an LED display screen with a viewing angle, which solves the problem that the traditional LED display screen cannot directly package the light-emitting diode on the surface of the PCB and the LED device, and cannot realize the colloidal surface of the LED device. Consistency, can not produce 180-degree visible effect, so that the problem of diffuse reflection on the surface of LED devices cannot be realized

Abstract

The invention discloses an LED display screen with a visual angle. The LED display screen comprises a first PCB panel and a second PCB panel, hneycomb hole ceramic chips are uniformly and fixedly connected to the top surface of the second PCB panel at equal intervals; light emitting diodes are fixedly connected to the top of the second PCB panel and located in gaps between the honeycomb hole ceramic pieces, diffusion agent colloid is used for filling in a gap position between the honeycomb hole ceramic chips and above the light emitting diode; and the top of the honeycomb hole ceramic piece isfixedly connected with a honeycomb hole aluminum sheet, pins are evenly arranged on the two sides of the top of the second PCB panel, and the bottoms of the pins penetrate through and extend to the position below the first PCB panel. According to the LED display screen with the visual angle, the consistency of the colloid surface of an LED device is achieved, the 120-degree visual effect is achieved, the process is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED display screen with a viewing angle. Background technique [0002] Traditional LED devices have flat colloidal surfaces and small roughness. When they are made into LED displays, it is easy to cause reflections on the entire display surface and affect the light output effect of the entire LED display. On the other hand, the colloidal surfaces of LED devices are flat. , easy to form glare phenomenon. Therefore, in order to solve the problem of light reflection on the surface of LED devices, realize diffuse reflection, and improve the light output effect of the entire LED display screen, it is necessary to increase the consistency of the colloidal surface of LED devices. [0003] Provide an LED display screen in which light-emitting diodes are directly packaged on the surface of the LED device on the PCB, which can realize diffuse reflection on the surface of th...
