More Information
Summary:The utility model relates to an optical touch control module with high signal-to-noise ratio, which comprises a sensing area, two sensors, at least two light emitting assemblies and at least two light guide assemblies, wherein the sensors are arranged at the edge of the sensing area; the light emitting assemblies are used for outputting at least one light signal; and the light guide assemblies are independently arranged at the edge of the sensing area and guide the light signals output by at least two of the light emitting assemblies to the sensing area. Thereby, the light signals generate a modulation mechanism by utilizing a plurality of groups of light emitting assemblies to filter and remove stray light entering from other directions so as to enhance the signal/noise ratio.
