Moisture Protection for Micro-LED Displays

Display device with improved encapsulation to prevent water and oxygen ingress into the display and degrade the device. The encapsulation involves covering the side surfaces of adhesive layers used to attach components like light-emitting diodes (LEDs) to the display substrate. This prevents external water and oxygen from penetrating through the adhesive sidewalls. The encapsulation is achieved by adding an extra encapsulation substrate that overlaps and contacts the adhesive layers. This ensures the side surfaces of the adhesive layers are fully covered. The additional encapsulation substrate can also have grooves in the upper portion to reduce stress when bending the encapsulation structure.

Moisture-proof LED display with nano coating to prevent water ingress in humid environments. The display has a nano coating on the LED components inside the case to prevent moisture absorption. It also has cooling fins, a heat insulation layer, sliding rods, and spring-engaged pressure plates for assembly without screws. This allows easier, faster, and more convenient assembly compared to using screws. The display also uses a thermal strip inside the case to dissipate heat from the LEDs without external holes that can let in water.

Waterproof LED display module that prevents water ingress without affecting display quality when submerged or exposed to rain. The module has a sealed packaging layer on the sides of the substrate to prevent moisture ingress there. The bottom of the module is sealed with a waterproof housing. This provides comprehensive protection of the substrate and LED chips without enclosures that can cause visual artifacts when spliced together.

Coated moisture-proof LED light source that prevents water ingress into the LED package to improve reliability in humid environments. The LED light source has a dam around the light-emitting area that encloses a filling area with a top opening. The dam surrounds the light-emitting chips and seals the edges. This prevents condensation and moisture from entering the LED package through gaps. The filling area can have a coating or sealing material to further block moisture.

An indoor waterproof and moisture-proof LED display module to prevent damage to the LED display screen from humidity and water. The module has a mounting frame with a transparent glass cover, a storage bin inside, and a sealing gasket and cover plate. Desiccant is put in the storage bin to absorb moisture. The sealing gasket and waterproof tape prevent water vapor from entering the frame. This protects the LED display inside from moisture and improves longevity.

Waterproof, moisture-proof and thermally dissipating LED display screen for indoor applications like signage and advertising. The display has a frame, a base plate, a coating plate and angled frames. The coating plate is attached to the base plate and has angled frames connected to the frame. This allows water and moisture to drain off the display while the angled frames facilitate heat dissipation to prevent overheating. The base plate provides a flat surface for the LED modules to be mounted on.

Moisture-proof display device to prevent water vapor from entering and damaging the LED chips. The display device has a waterproof seal around the entire edge of the circuit board, not just where the 1B port chip is located. This provides a tight seal between the board edge and the waterproof material to prevent water vapor intrusion and detachment issues.

Breathable and waterproof micro LED display for wearable electronics that allows airflow to prevent fogging and condensation while still being waterproof. The display has air channels in the substrate that connect to the surface. A hydrophobic layer covers the display side and a hydrophilic or hydrophobic layer covers the back. This prevents water entry through the back while allowing airflow through the channels. The channels connect to the surface to allow air exchange with the environment. The micro LEDs have small size less than 2500um^2 to enable breathability.

LED display screen with better moisture-proof capability to prevent water vapor from entering the display and damaging components. The display is enclosed in a sealed protective box with a cover plate, sealing plate, and protective glass. Inside the box, a drying box contains desiccant to absorb moisture. The cover plate can be pushed up to open the box for heat dissipation. Moving the card plate opens the sealing plate to remove the drying box with desiccant. This allows easy replacement of the desiccant without disassembling the display.

Display device with improved moisture protection and easier rework capability. The display has a moisture barrier hole in the bezel area of the substrate. This hole penetrates through layers like the coatings and bank insulation. A packaging component fills at least part of the hole. This prevents moisture ingress into the bezel region. It also allows easier separation of the display from the substrate during rework compared to bonded packages. A variable adhesive layer between the encapsulation and front adhesive layers reduces bond strength under UV light. This enables easier removal of the display from the substrate without damaging the LEDs.

Enhancing waterproofing of SMD LEDs to prevent internal moisture intrusion that can cause failures like metal migration and leakage. The LED has a unique waterproof assembly at the junction of the encapsulating resin and substrate. The assembly includes features like water stop strips, arc plates, springs, and rods that expand and contract to push water out when absorbed. This allows the LED to automatically replace water-stop strips during operation, preventing water ingress into the interior of the LED.

Micro LED display device with improved color accuracy and water/oxygen protection. The display has a positioning frame outside the display area to align the substrates precisely. An isolation frame surrounds the positioning frame and has lower moisture vapor transmission rate. This prevents water and oxygen ingress into the display area. A cover plate connects the substrate to the frames. The positioning frame provides alignment while the isolation frame blocks environmental factors.

Micro LED display device with improved packaging to prevent chromatic aberration when using quantum dot (QD) materials. The display has a positioning frame outside the display region to connect the cover plate to the substrate. An isolation frame surrounds the positioning frame to block environmental factors like water and oxygen from the QDs. The isolation frame has a lower water vapor transmission rate than the positioning frame to protect the QDs better. This prevents chromatic aberration when viewing the display from wider angles.

Moisture-proof and waterproof LED display device to prevent fogging and condensation on the display screen in humid environments. The device uses a waterproof frame around the display panel, with drying blocks on the backside to absorb moisture. The drying blocks are connected to the frame bottom and have heat dissipation mechanisms nearby. A sealing mechanism with a hinged plate and moving rods secures the front of the water tank. This provides moisture removal inside the frame while allowing heat dissipation, preventing internal fogging.

LED display screen outdoor module with improved waterproofing and prevention of lifting of the LED board. The module has a soft bottom case with a protrusion along the front edge. The LED board is placed inside the protrusion and a glue accommodating groove is provided on the case inner wall. A glue filling layer seals the LED board edges and fills the gap between board and protrusion. When glue is applied to the board front, it enters the groove. This wraps and fixes the board edges to the case, preventing lifting.
