Unilumin Technology has obtained patents for "LED modules and LED display screens"
Recently, Unilumin Technology has disclosed patents for "LED modules and LED display screens", "LED packaging devices and their manufacturing methods, LED modules and their manufacturing methods".
Among them, the patent application number of "LED module and LED display screen" is CN202311567660.3, and the application date is November 22, 2023.
The patent abstract shows that this application relates to LED modules and LED displays. The LED modules
It includes a panel, a PCB substrate and an LED light-emitting chip arranged on the PCB substrate. The panel is covered on the PCB substrate and the LED light-emitting chip; the PCB substrate is provided with a relief groove, and the relief groove surrounds all the LED light-emitting chips; the panel is provided with a protrusion on one side facing the display surface, and the protrusion is adapted to the relief groove so that the protrusion surrounds all the LED light-emitting chips. The above-mentioned LED module changes the position of the joint seam between the LED panel sealant material and the PCB substrate through the design of the avoidance groove combined with the protrusion, thereby realizing the sealing of the joint seam and protecting the PCB substrate exposed by the joint seam. This prevents water vapor from contacting the LED light-emitting chips, circuits and other components on the PCB substrate through the joint seam. It can be applied to the outdoor waterproof module design of the general outdoor COB process.
"LED packaging device and its manufacturing method, LED module and its manufacturing method" patent application number is CN202311504008.7, application date
is November 10, 2023.
The patent abstract shows that this application relates to an LED packaging device and its manufacturing method, LED module and its manufacturing method. The LED package device includes: a substrate; an LED chip, the LED chip is disposed on the substrate; an encapsulant, the encapsulant is disposed on the substrate and covers the LED chip; the encapsulant includes a first section and a second section located on top of the first section; the first section and the second section have an integrated structure; the orthographic projection of the second section on the substrate is within the orthographic projection of the first section on the substrate; and a light-blocking wall, which covers the outer side of the second section, and is arranged around the LED chip. The light-blocking wall can block the lateral light emission of the LED package device, so that the LED package device is configured as a top light-emitting device. When LED modules including multiple LED package devices are spliced into a display screen, it is helpful to avoid problems such as colored lines and dark bright lines at the splicing caused by lateral light emission. This can improve the splicing display effect.

"A hasp lock for assembling LED display screens" patent application number is CN202111129781.0, and the application date is September 26, 2021.
The patent abstract shows that the present invention proposes a hasp lock for assembling an LED display screen, including a first lock body and a second lock body. The first lock body includes a first body and an angle frame that can rotate relative to the first body. The angle frame is provided with at least two first positioning surfaces with different inclination angles. The second lock body includes a second body and a positioning part. The positioning part is fixedly connected to the second body. One end of the positioning part is provided with a second positioning surface. The second positioning part is fixedly connected to the second body. The plane coincides with the first positioning surface; there are three first positioning surfaces, and the inclination angles of the three first positioning surfaces are 5 degrees, 0 degrees, and +5 degrees respectively. The first lock body and the second lock body are respectively installed on two adjacent LED display screens. When joining together, the inclination angle of the first positioning surface is selected according to the curvature of the LED display screen. The curvature of the two adjacent LED display screens can be adjusted by making the second positioning surface match the first positioning surface.

Alto Electronics obtained patents such as "an LED display box"
On February 23, Alto Electronics' patents for "an LED display box", a curved screen frame and an LED display", and "a water intrusion warning LED display box" were authorized.
Among them, the patent application number for "an LED display box" is CN202322152837.5, and the application date is August 10, 2023.
The patent summary shows that this application relates to the field of LED display technology, in particular to an LED display box. An LED display box includes an LED display module, a frame, a power box, a signal box and a top protection pad.
