A micro multi-color LED device includes two or more LED structures for emitting a series of color light. The two or more LED structures are vertically stacked to mix the light emitted by the two or more LED structures vertically and / or horizontally and reflect upward via some reflective structures. In some embodiments, each LED structure is connected with a pixel driver and / or a common electrode. The LED structures are bonded together by a bonding layer. In some embodiments, a planarization layer encloses each LED structure or the micro multi-color LED device. In some embodiments, one or more of a reflective layer, a refractive layer, a microlens, a spacer, and a light reflecting cup structure are implemented in the device to improve the LED light emitting efficiency.

This invention discloses a display panel, its fabrication method, and a display device. The display panel includes a driving substrate; light-emitting elements located on one side of the driving substrate and electrically connected to the driving substrate; and a light-shielding barrier located on one side of the driving substrate and between two adjacent light-emitting elements. The light-shielding barrier includes a first surface closer to the driving substrate and a second surface farther from the driving substrate, wherein, along the thickness direction of the display panel, the coverage area of ​​the second surface is larger than that of the first surface. Thus, by setting the coverage area of ​​the second surface to be larger than that of the first surface, more external light is absorbed through the larger second surface, reducing interference from external light on the light emitted by the display panel. Simultaneously, setting the coverage area of ​​the first surface to be smaller than that of the second surface allows for more space to be reserved for the light-emitting elements, reducing fabrication difficulty and facilitating the placement of a larger number of light-emitting elements in the display panel, thereby improving display resolution.

The application discloses a method for preparing a quantum dot color conversion layer based on a microchannel and electrophoretic deposition, which comprises the following steps: setting a metal ring electrode and a connecting electrode on the periphery of an array-arranged transparent electrode, depositing an insulating layer, opening a to-be-deposited area, using a micro-channel technology, bonding with a micro-channel cover plate, and then feeding a charged quantum dot solution into a micro-channel passage, combining with an electrophoretic deposition technology, so that the quantum dot solution is deposited on the transparent electrode of the to-be-deposited area to form a quantum dot unit. The prepared quantum dot color conversion layer is bonded with a Micro-LED chip array to realize full-color display. The application combines the micro-channel technology and the electrophoretic deposition technology through the design of the metal electrode surrounding the transparent electrode, realizes the quantum dot color conversion layer with the advantages of small pixel size, high PPI, high light emission uniformity, fast deposition speed, high raw material utilization rate and being conducive to large-area preparation, and thus promotes the industrialization of the full-color Micro-LED.

This invention relates to the field of brain function monitoring and discloses a closed-loop transcranial photostimulation (tPBM) modulation method and system based on near-infrared brain response characteristics. First, fNIRS signals of the target brain region of the subject are acquired. After the fNIRS signals pass through the data pathway, preprocessing and windowing calculations are performed to extract dynamic response characteristics. By setting the difference detection between the baseline and stimulation periods, blood oxygen response indicators are calculated, and based on these indicators, the current brain region is identified as having enhanced, sluggish, inhibited, or fatigued responses, yielding the change in HbO. Through the real-time acquisition of HbO changes, features such as the instantaneous rate of change and peak response of indicators like Δ[HbO] and Δ[HbR] are extracted to construct an individual's "baseline-response" curve model for parameter optimization and control, completing the tPBM stimulation modulation. This invention solves the problems of equipment redundancy, spatial interference, poor synchronization, difficulty in achieving real-time coordination between intervention and imaging, and poor measurement stability and accuracy in existing technologies.

This invention discloses a high-precision self-stabilizing tunnel construction positioning and marking robot, relating to the field of tunnel construction technology. It includes a crawling robot, a fixing mechanism, a third motor, a conversion mechanism, and a lifting mechanism. The crawling robot has fixing mechanisms rotatably connected to all four sides of its bottom. A third motor is fixedly connected to the top of the front boss of the crawling robot, and the bottom output shaft of the third motor passes through the front boss and is rotatably connected to its interior. A conversion mechanism is fixedly connected to the bottom output shaft of the third motor. A lifting mechanism is fixedly connected to the top right front end of the crawling robot platform. The fixing mechanism, by drilling holes in the tunnel wall and inserting a first drill bit into the holes, fixes the crawling position of the robot, reducing the accumulation of small deviations and preventing the overall trajectory from deviating from the design path.
