Description

A commercial display-oriented device based on display products

technical field

The present invention relates to the field of display technology, in particular to a commercial display-oriented device based on a display product.

Background technique

At present, small-pitch display screens mainly use separate device display or positive chip bonding wire display, and the display effect has obvious point light source state. At present, the display screen cannot meet the needs of end-use customers in the current commercial display promotion, which restricts With the promotion of the small-pitch display market, the present invention can effectively solve the current small-pitch display with point-light-like light-emitting and commercial display customer groups that require a thin, flat screen and the like.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a commercial display-oriented device based on display products in view of the defects and deficiencies of the prior art. Uncontrollable abnormal factors appear in the link, and greatly shorten the manufacturing process and cycle, and at the same time use a completely horizontal protective medium and film-coated medium, which can meet the flatness requirements and change the shortcomings of the current point light source display, and can realize the LED display. It is better for the application and promotion of commercial display.

In order to achieve the above object, the present invention adopts the following technical solutions: it includes a PCB substrate 1, a light-emitting device 2, a protective medium 3, and a film-coated medium 4, the light-emitting device 2 is fixed on the upper surface of the PCB substrate 1 by soldering, and the light-emitting device 2 is externally arranged. The protective medium 3 is provided with a film-coated medium 4 on the outer surface of the protective medium 3, and a plurality of scattering particles are dispersed in the film-coated medium 4.

The protective medium 3 includes diffusion powder and toner, and the thickness of the protective medium 3 is 2-5 mm.

The particle size of the scattering particles dispersed in the film-covered medium 4 is 1-10 μm, the thickness of the film-covered medium 4 is 50-200 μm, and the outer surface of the film-covered medium 4 away from the PCB substrate 1 is a direction away from the PCB substrate 1 . Raised arc shape.

The working principle of the present invention: the flip-chip welding chip is directly welded on the substrate, including a protective medium, a thin film medium and a coating process for uniformly scattering the light emitted by the LED light-emitting chip, so as to convert the point light source formed by the current display device illuminant. Converted into a surface light source and make the display body suitable for commercial display.

After adopting the above technical solution, the present invention has the following beneficial effects: its structural design is reasonable, the traditional device-type light-emitting display is completely changed, the encapsulation link is reduced, the uncontrollable abnormal factors in the current encapsulation link can be solved, and the manufacturing process is greatly shortened. At the same time, it adopts a completely horizontal protective medium and film-coated medium, which can meet the flatness requirements and change the shortcomings of the current point light source display, and can realize the application and promotion of the LED display body for better commercial display.

Detailed ways

Referring to FIG. 1, the technical solution adopted in this specific embodiment is: it consists of a PCB substrate 1, a light-emitting device 2, a protective medium 3, and a film-coated medium 4, and the upper surface of the PCB substrate 1 is fixed by soldering. In the device 2, a protective medium 3 is provided outside the light-emitting device 2, a film-coated medium 4 is provided on the outer surface of the protective medium 3, and a number of scattering particles are dispersed inside the film-coated medium 4.

The protective medium 3 contains diffusing powder and toner for diffusion, and the thickness of the protective medium 3 is between 2-5 μm.

The particle size of the scattering particles dispersed in the film-coated medium 4 is between 1-10 μm, the thickness of the film-covered medium 4 is between 50-200 μm, and the film-covered medium 4 is far away from the outer surface of the PCB substrate 1 . A circular arc that protrudes in the direction of PCB substrate 1.

The working principle of the present invention: the flip-chip welding chip is directly welded on the substrate, including a protective medium, a thin-film medium and a coating process for uniformly scattering the light emitted by the LED light-emitting chip, so that the point light source formed by the illuminant of the current display device is formed. Converted into a surface light source and make the display body suitable for commercial display.

After adopting the above technical solution, the present invention has the following beneficial effects: its structural design is reasonable, the traditional device-type light-emitting display is completely changed, the encapsulation link is reduced, the uncontrollable abnormal factors in the current encapsulation link can be solved, and the manufacturing process is greatly shortened. At the same time, it adopts a completely horizontal protective medium and film-coated medium, which can meet the flatness requirements and change the shortcomings of the current point light source display, and can realize the application and promotion of the LED display body for better commercial display.

The above is only used to illustrate the technical solution of the present invention and not to limit it.
