Document Type and Number:
WIPO Patent Application WO/2024/082396
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and apparatus for determining a transmitting gain, a device, a medium and a product. The method for determining a transmitting gain comprises: controlling a plurality of infrared transmitting lamps in an infrared touch screen to sequentially transmit infrared signals according to respective corresponding transmitting gain values; acquiring signal strength values of the infrared signals received by a plurality of infrared receiving lamps corresponding to the plurality of infrared transmitting lamps to obtain a signal strength array; when a first signal strength value in the signal strength array is smaller than a preset strength threshold, and a transmitting gain value of a first infrared transmitting lamp corresponding to the first signal strength value is smaller than a preset maximum gain threshold, increasing the transmitting gain value of the first infrared transmitting lamp according to a preset step size; and circularly executing until the first signal strength value is not smaller than the preset strength threshold to obtain target transmitting gain values respectively corresponding to the plurality of infrared transmitting lamps. According to embodiments of the present application, the touch detection effect of an infrared touch screen can be improved.
