Tailong Vision applied for a patent for an LED display debugging method and system

According to information from the State Intellectual Property Office on August 18, 2025, Shenzhen Tailong Vision Technology Co., Ltd. applied for a patent titled "An LED display debugging method and system", with the publication number CN120496451A, and the application date is July 2025.

The patent abstract shows that this application relates to the field of display technology, specifically, to an LED display screen debugging method and system. The method includes: obtaining first calibration data that characterizes the physical display characteristics of each pixel area of the LED display screen. The first calibration data describes the chromaticity and brightness attenuation caused by long-term operation; extracting the color characteristic summary of the input source, and the color characteristic summary includes the main color. tone range, color space parameters and brightness distribution characteristics; according to the color characteristic summary, the corresponding second calibration data is obtained from the preset calibration strategy library. The calibration strategy library records the calibration scheme that prioritizes ensuring the accuracy of key color display for different color characteristics; based on the first calibration data and the second calibration data applied to the input signal of the input source, automatic color debugging of the display effect is completed.

Leen Education applied for a patent for a modular multimedia display screen structure

News on August 16, 2025, information from the State Intellectual Property Office showed that Dongying City Leen Education Consulting ServiceCo., Ltd. has applied for a patent titled "A Modular Multimedia Display Structure", with the publication number CN120499970A, and the application date is May 2025.

The patent abstract shows that the present invention belongs to the technical field of LED display screens, and in particular relates to a modular multimedia display screen structure, which includes a storage base and an LED display screen body. A storage cavity is provided in the storage base, and a "∟"-shaped gap is opened at the end of the storage base and communicates with the storage cavity. slot, a rotating shaft is slidably provided in the storage cavity, the end of the LED display screen body is fixed on the outer wall of the rotating shaft, a cleaning tank located under the missing slot is provided in the storage base, rotating rods one and two are installed in the cleaning tank, and a driving motor is provided in the cleaning tank to drive rotating rod one to rotate. By arranging multiple modules to connect with the LED display screen body, the present invention facilitates the storage of the LED display screen body and at the same time can realize the cleaning and heat dissipation work of the LED display screen body. It can also clean the velvet layer of the LED display screen body for cleaning and drying work, so that the velvet layer is always kept clean and can work continuously, avoiding the inconvenience of replacement.

Guangdong Yuanheng Optoelectronics applied for a patent for an automatic maintenance robot for LED displays to restore the waterproof performance of LED displays

According to information from the State Intellectual Property Office on August 16, 2025, Guangdong Yuanheng Optoelectronics Co., Ltd. applied for a patentThe patent is called "An automatic maintenance robot for LED display screens", the public number is CN120479696A, and the application date is July 2025.

The patent summary shows that the invention discloses an automatic maintenance robot for LED display screens, which is used in maintenance operations of LED display screens. The LED display screen includes a box and an LED display light panel installed inside the box. A first sealant is provided at the joints of the boxes. The LED display automatic repair robot includes: a moving mechanism; a glue removal mechanism connected to the moving mechanism for removing the first sealant connected to the box; and a glue applying mechanism connected to the moving mechanism for applying a second sealant to the joints of the box. The LED display automatic maintenance robot of the present invention accurately transports the glue removal mechanism and the glue application mechanism to the splicing of the box through the movement of the moving mechanism on the contact surface. The glue removal mechanism removes the aged first sealant, and the glue application mechanism applies the new second sealant to the box splicing, thereby updating the sealant and restoring the waterproof performance of the LED display. The use of the LED display automatic maintenance robot reduces labor costs and also reduces the labor intensity of workers.
