Absen obtained utility model patent authorization:

According to data from Tianyancha APP, Absen (300389) has newly obtained a utility model patent authorization. The patent is called "Temperature detection circuit and LED display system for LED display screen". The patent application number is CN202422512694.9, and the authorization date is August 12, 2025.

Patent abstract: This application discloses a temperature detection circuit and an LED display system for an LED display screen. The temperature detection circuit includes multiple temperature detection modules. The multiple temperature detection modules correspond to the multiple LED light panels included in the LED display screen. The temperature detection module includes: a temperature detection unit, which is disposed on the LED. The light board is used to detect the temperature of the LED light board and output a power control signal based on the detected temperature information; the power control unit is connected to the temperature detection unit and is also connected between the LED light board and the power supply, and is used to control the conduction and disconnection between the LED light board and the power supply based on the power control signal output by the temperature detection unit. The technical solution of this application can conduct temperature detection separately for each LED light panel in the LED display screen, refining the granularity of temperature detection of the LED display screen; when the temperature of any LED light panel is abnormal, the position of the light panel can be quickly determined through the temperature detection unit corresponding to the corresponding LED light panel, thereby improving the maintenance efficiency of the LED light panel.
