Description

TECHNICAL FIELD

[0002] In the prior art, the LED display screen box as an important component of the display screen is widely used in advertisement display, large stage performance, conference system and other scenes. The traditional LED display screen has some problems in installation, maintenance and display effect.

[0003] 1. The installation of the traditional LED display screen usually needs to use threaded fixing, welding connection and other ways. Although this way can provide certain stability, the installation process is tedious, time-consuming and needs professional tools and personnel operation; in the scene of frequent replacement or rapid deployment (such as stage performance or temporary display activities), the complex installation mode will significantly reduce the work efficiency, increase the construction time and labor cost.

[0004] 2. The traditional LED module is connected with the box frame by the way of buckle or fixed screw, but the buckle is easy to loosen or the screw connection is not firm during transportation, installation or use, which leads to the risk of falling off of the LED module. The module falling off not only may cause damage to the equipment itself, but also has safety hazards, especially in the scenes of stage, outdoor advertisement and other dense human flow.

[0005] 3. The lamp beads of the traditional LED module generally adopt TOP structure, which is easy to see the white background color due to the exposure of the lamp bead pin, leading to low contrast and poor display effect. In addition, the module packaging adopts transparent resin material, which will produce "mirror reflection" after reflecting light, affecting the visual angle and picture clarity. In the high brightness scene (such as film and television shooting scene) or the occasion with high requirement on display effect (such as performance background screen), the picture quality is insufficient, which cannot meet the user demand.

[0030] The LED module uses all-black flip-chip LEDs. Employing a chip design, it avoids the common cathode structure where the LED pins are easily exposed, making the white areas visible. The high-brightness flip-chip paired with an all-black frame delivers exceptionally high contrast. Combined with an ultra-thin matte black encapsulation process, it ensures no specular reflection, achieving a wide viewing angle. It also features high reliability, long lifespan, and stable color consistency. This LED module uses an ultra-black GOB encapsulation method. Existing conventional GOB encapsulation uses transparent polymer resin, resulting in a grayish-white background on the display screen or application screen, leading to low brightness and contrast and unclear display. This LED module addresses the color difference problem caused by adding a black agent or other colorant to a black high-transparency resin composition, thereby increasing contrast and resolving inconsistencies in the PCB background color.
