The patent abstract shows that the patent discloses a multi-mode micro-LED display for a head-mounted device that can switch between two or more complementary display modes with different colors and/or resolutions. These modes can help heads-up displays using micro-LEDs display information to users in a variety of display scenarios without simply increasing the power consumed by the micro-LEDs. These modes can be supported by display software and display hardware. Switching between alternative modes may be based on content for display, user input, environmental conditions, and/or conditions of the headset.

It is worth noting that Google is actively promoting the development of AR glasses business. In April this year, Google publicly demonstrated for the first time an AR glasses prototype equipped with a micro display and Gemini AI assistant, as well as the MR headset "Infinity" jointly developed with Samsung. Google demonstrated the device’s multi-scenario applications live, including real-time interaction with AI agents.

The patent abstract shows that the patent describes a miniature multi-color LED device that includes two or more LED structures for emitting a range of colors of light. The two or more LED structures are stacked vertically to mix the light emitted by the two or more LED structures vertically and/or horizontally and reflect upwardly via some reflective structure.

In some implementations, each LED structure is connected to a pixel driver and/or a common electrode. The LED structures are bonded together through bonding layers. In some implementations, a planarization layer surrounds each LED structure or miniature multi-color LED device. In some implementations, one or more of a reflective layer, a refractive layer, a microlens, a spacer, and a reflective cup structure are implemented in the device to improve the LED luminous efficiency. Display panels including micro three-color LED device arrays have high resolution and high lighting brightness.

The patent abstract shows that the present invention relates to a method and device for mass laser transfer of Micro-LED microdisplay devices, which includes the following steps: photographing the microdisplay device of the dissociated Micro-LED microdisplay device to obtain the position of the Micro-LED microdisplay device and the morphological image of the Micro-LED microdisplay device; picking up the dissociated Micro-LED microdisplay device to the target substrate based on the position of the Micro-LED microdisplay device and the morphological image of the Micro-LED microdisplay device to obtain the transferred Micro-LED microdisplay device array;

Fix the transferred Micro-LED microdisplay device array to obtain a Micro-LED microdisplay device array fixed on the target substrate; perform an electrical performance test on the Micro-LED microdisplay device array fixed on the target substrate to obtain the electrical performance parameters, and set the electrical performance parameters lower than the electrical performance The Micro-LED micro-display devices that can meet the parameter threshold are eliminated to obtain a qualified Micro-LED micro-display device array, which solves the technical problems of traditional transfer methods such as mechanical transfer and printing transfer, which are usually inefficient and easily damage tiny Micro-LED micro-display devices during the transfer process.

The patent abstract shows that embodiments of the present invention provide a display backplane and a Micro-LED display panel to solve the technical problem of splicing gaps in existing Micro-LED display panels spliced ​​with side metal wiring, which seriously affects the display effect. The display backplane is made of materials with a dielectric constant less than 10, which effectively reduces the capacitive coupling effect, reduces power consumption, and improves the integrity and thermal stability of signal transmission;

The display backplane realizes linear electrical connection between the front wiring layer and the back wiring layer through a through-hole vertical interconnection structure, realizing the replacement of side metal traces and completely avoiding the occupation of the side space of the display backplane caused by side metal traces. The display backplane maintains a completely flat side structure. Furthermore, through a simple, easy-to-implement, high-yield splicing process, the spliced ​​sides of multiple Micro-LED display panels can be closely aligned to form a Micro-LED display with consistent display effects.

Hongshengda applies for anti-glare Micro LED display patent

According to information from the State Intellectual Property Office, Shenzhen Hongshengda Optoelectronics Technology Co., Ltd. applied for a patent titled "An anti-glare Micro LED display and its anti-glare adjustment method and system", with the publication number CN119811279A, and the application date is March 2025.

The patent abstract shows that the present invention relates to the technical field of display screens and discloses an anti-glare Micro LED display and its anti-glare adjustment method and system. The method includes: collecting multi-dimensional spectral data of incident light to obtain a multi-dimensional spectral characteristic matrix; performing spatio-temporal light field reconstruction of tensor decomposition and spherical harmonic expansion operations on the multi-dimensional spectral characteristic matrix to obtain four-dimensional light field characteristic data; inputting the four-dimensional light field characteristic data into a deep learning prediction network for dynamic modeling to obtain light field distribution prediction data;

Optimize the anti-glare display parameters based on the light field distribution prediction data to obtain the display parameter target values; execute a hierarchical hierarchical control strategy based on the display parameter target values to generate multi-parameter collaborative control signals of light transmittance adjustment, polarization state modulation and microstructure actuation. This method achieves accurate conversion from light field characteristics to control parameters while ensuring the stability and continuity of the display effect, effectively reducing system energy consumption and improving operating efficiency.
