LED display module and manufacturing method thereof

Abstract

The invention belongs to the field of LED display, and provides an LED display module and a manufacturing method of the LED display module. Light beads in the LED display module are fixed to the surface of a linearly arranged light bead plate, the light bead plate is fixed to a driving PCB, the surface of the light bead plate is perpendicular to the surface of the driving PCB, the surface of the driving PCB is perpendicular to the surface of a glass plate, and a fixing part is fixed to a framework. The highly transparent glass plate serves as the installation main body, the driving PCB is transversely arranged on the glass plate, shielding of light by the driving PCB is largely reduced, and the transparency of the LED display module is improved. Meanwhile, the multiple light beads are fixed to the surface of the linearly arranged light bead plate, and the pixel density of the LED display module is improved. The invention further provides the manufacturing method of the LED display module. The LED display module is high in density and transparency to meet the requirements for a high-pixel-density and high-transparency LED display module of the market.

Description

technical field [0001] The invention relates to the field of LED display, in particular to an LED display module and a preparation method thereof. Background technique [0002] Due to its flexible size and strong environmental adaptability, LED display screens are widely used in the media field. At present, the LED display devices commonly used in the market are generally black box-type, light bar screens, and grid screens. way structure and strip structure. [0003] In some special occasions, such as glass curtain walls, shop windows, stage backgrounds, shopping malls, hotels, airports and other environments, LED display modules need to have high permeability, good lighting and perspective effects, and at the same time maintain a certain pixel density, while black LED display devices with box-type, light bar screen, and grid screen structures cannot coordinate with the surrounding environment. For example, installing a box-type LED display device on a glass curtain wall or...

Problems solved by technology

[0003] In some special occasions, such as glass curtain walls, shop windows, stage backgrounds, shopping malls, hotels, airports and other environments, LED display modules need to have high permeability, good lighting and perspective effects, and at the same time maintain a certain pixel density, while black LED display devices with box-type, light bar screen, and grid screen structures cannot coordinate with the surrounding environment. For example, installing a box-type LED display device on a glass curtain wall or background wall will completely block the light and lose The effect of light transmission, but the light strip screen and the grid screen are difficult to meet the glass curtain wall structure of various sizes. If the cost is greatly increased, it is very inconvenient and post-maintenance. However, the strip LED display screen, this kind of LED screen is to use LED to emit light The unit is installed on a strip-shaped circuit board, and then fixed with an opaque shell. Several such light strips form a unit module, and several unit modules are cascaded to form a display screen.

Because the opaque shell takes up a lot of space, the pixel pitch of this unit module generally needs to be more than 40mm to have a certain light transmission effect, but if the pixel pitch is too large, it is not suitable for applications with a small viewing distance

At the same time, because the strip structure of this opaque display module is very obvious, no matter it is installed indoors or outdoors, it will give people a sense of restraint, and it is not suitable for high-end applications such as shop windows and glass curtain walls of shopping malls. The market calls for both High pixel density and high permeability LED display
