Modular Designs for Micro-LED Display Production

LED display control method, LED display screen and its control system that simplifies wiring and improves stability of LED displays. The method involves converting parallel image signals from the module control device into serial signals. The display modules are connected in series and analyze the serial signals to extract their individual display data. This allows multiple modules to be connected with fewer interfaces and cables compared to parallel connections.

Display device with customizable modular LED displays that can be assembled into any shape. The modular LED displays each have their own controllers and power connections. The modular displays are manufactured by processing them based on their specific shapes. The processed modules are then assembled into the final display. This allows creating displays of arbitrary shapes by optimizing the modules for each shape instead of designing custom displays for each shape. The central processor converts and sends content to the module controllers based on their shapes.

LED display module and LED display device with simplified architecture to reduce development time and cost compared to traditional LED display modules. The LED display module has a main control chip with an instruction decoder, storage unit, and DMA channel. The decoder converts instructions into control signals for operations. The chip connects to the LED driver chip via a bus. This eliminates separate capture, sending, and scanning cards. The display device has a control system with a transmission interface, data processing chip, and component with multiple interfaces. The LED modules connect to the component interfaces. The control system also has an instruction memory for power-on initialization.

LED display screen with integrated control module inside the display module enclosure to eliminate the need for a separate control box. The display has multiple modules with lamp panels inside boxes. One module per box has the control module. This allows splicing different numbers of modules for variable display sizes. The control module is connected to the lamp panels inside the box using wiring. This integrates the control electronics into the display enclosure, simplifying manufacturing, installation, and maintenance versus external control boxes. The integrated design enables thin, full-screen LED displays.

Micro LED display device that can be connected to neighboring micro LED displays to form a tiled display system without requiring individual setup. The displays have terminals on their side surfaces to connect to adjacent displays. Each display contains a controller that can communicate with connected displays using packets containing arrangement and identification data. This allows the displays to exchange data and synchronize without a central controller.

Modular LED display panels with different pixel pitches that can be combined to create custom resolution displays without needing multiple sizes. The panels have the same size and shape but different pixel pitches. This allows interconnecting and tiling the panels with different resolutions to form larger displays without needing custom-sized panels for each resolution.

LED display screen that improves resolution and reduces cost compared to fixed displays. The display has LED modules that can swing back and forth in parallel with the screen surface. This allows the modules to move while displaying images to fill in gaps and improve coverage. The swinging motion is synchronized with the video to maintain display while moving. This prevents pixelated or pointy images. It also reduces the number of modules needed for equivalent resolution versus fixed screens.

Compact multi-color LED display module for emissive displays like televisions, computers, and smartphones that enables high resolution and multi-viewpoint displays. The module has a fixed number of LEDs per group, like 2, and a separate bias circuit for each group to individually control the LEDs. This allows simultaneous emission with common timing. The bias circuits can adjust LED power through current or time modulation. Multiple modules can display a pixel with subpixels from different colors. This allows compactness, parallel processing, and flexibility for multi-viewpoint displays.

Optimizing pixel uniformity in microLED displays by selectively placing tiles based on a predetermined parameter. The parameter could be microLED brightness or color accuracy. The method involves sorting tiles based on their parameter values, then assembling the display using sorted tiles. Adjacent tiles are paired with one having a higher parameter value than the other. This helps mitigate pixel non-uniformities.

Thin LED display device that reduces size and eliminates the need for separate power and video modules. The display has individual LED units connected in a cascade. Each unit has a power converter, row driver, and column driver. The units can be connected via a composite interface that combines power and video signals. This allows transmitting power and video through a single connection instead of separate modules. This simplifies the display design, reduces size, and eliminates the need for an external power and video box.

Reducing pixel pitch of microLED displays by separating the driver circuitry from the microLED array. The microLED matrix is on one side of a substrate and driver circuits are on the other side. Conductive paths in the substrate connect the microLEDs to the drivers. This allows reducing pixel size beyond the microLED size limitation. A separate driver circuit provides scan and PWM signals to the matrix drivers. The matrix drivers then control the microLEDs based on the scan and PWM signals.

Energy-saving Micro LED display screen that reduces power consumption by allowing individual LED modules to be turned off when not in use instead of the entire display. The display has a main control module, power supply module, and multiple LED modules. Each LED module has an interface to connect to the control and power modules. The control module converts video data and sends it to the LED modules. The power module supplies power to the display. When a module is not needed, the control module can disable power to that module instead of the whole display.

Micro LED display with high resolution and compact layout to improve display quality and density. The micro LED display has a circuit board with micro LEDs having pixel arrays. A controller on the board drives the micro LEDs. The controller has an interface, data driving circuit, and core circuit. The interface receives command/data signals. The core circuit generates compensated display info based on micro LED arrangement in each pixel. The data driving circuit generates control signals for the micro LEDs using the compensated info. This allows packed micro LED displays with high resolution and compact layout as the controller optimizes the display signal for each micro LED.

Spliced micro LED display panel with improved yield and reduced size compared to individual micro LED transfer. The panel is made by connecting multiple micro LED modules to circuit boards. The modules are stacked and bonded together with smaller gaps between adjacent modules on adjacent boards. This reduces transfer time and improves yield versus transferring individual micro LEDs. The modules have features like internal circuits, conductive vias, and light-blocking layers to enable stacking and bonding.

Micro LED display with high resolution and improved display quality using a single controller. The display has closely packed micro LED devices on a circuit board. A single controller drives the micro LEDs by transmitting signals to control their display statuses. The controller calculates compensated display data based on the micro LED arrangement to improve image quality. By reducing the pitch between micro LEDs and using a single controller, the display resolution is increased compared to one-to-one control.

Fluidic assembly of high-resolution microLED displays using a specific LED shape and trap structure to enable self-alignment during assembly. The microLEDs have vertical electrodes and a unique shape. The display substrate has wells with matching shapes and platforms for the microLED electrodes. When suspended microLEDs flow over the substrate, they self-align in the wells due to the shape match. This allows precise positioning of millions of microLEDs using fluidic assembly for high-resolution displays.

Micro LED display device with redundant elements and dynamic compensation to mitigate defects and improve yield. The display has more LED rows and columns than needed to compensate for dead pixels. A mechanism moves the excess LEDs to cover defective areas. The controller manages the LED array and movement to display an image without defects.

LED display system that simplifies implementation of LED display systems by modularizing the LED panels, allowing easier configuration and setup compared to traditional wired connections. The system uses a centralized control unit that determines the data path layout and power path layout of the LED display system. Each LED panel has a connection interface to receive display data and send it to adjacent panels for daisy-chaining. The control unit sends the data to the first panel, which then spreads it through the panel chain. The control unit also sets display parameters like scan frequency and brightness centrally for the entire system. This modular, daisy-chained configuration allows easy connection and setup of the LED panels without needing to know the details of each panel.

MicroLED display with reduced visible seams between modules. The display uses tile-shaped microLED modules that can be more easily handled and assembled than individual microLEDs. The modules are arranged on a display substrate with some modules bridging the gaps between others. The bridging modules have wider top plates that extend beyond the center bodies, allowing their LEDs to cover the gaps between adjacent modules. This reduces the visible seams between modules compared to the normal modules.

Micro LED display with reduced seams between modules to improve image quality. The micro LED modules have inclined side surfaces that match each other when adjacent. This allows modules to be tiled together with minimal seams visible between them. The inclined sides reduce the linear defects that would be seen if the sides were perpendicular. This is because the inclined sides create a zigzag pattern that breaks up the defect lines. The angled sides can be achieved by etching or molding the module substrate at an angle relative to the LED surface.
