Embodiment Construction
[0045] The present invention provides an adaptive infrared touch screen and its precision control method. Through the processing module, find out the infrared emitting lamps that emit infrared signals that are too strong or too weak, and adjust their emission power so that the infrared signals emitted by each infrared emitting lamp are consistent. The automatic control of infrared touch screen precision has effectively solved the problem of standardization of infrared touch screen mass production signals, and at the same time improved the resolution of infrared touch screen and increased its ability to resist sunlight interference.
[0046] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invent...

The invention discloses an adaptive infrared touch screen and a precision control method thereof, wherein the adaptive infrared touch screen includes an infrared emitting module, an infrared receiving module and a processing module; the processing module compares each infrared emitting module in the infrared emitting module The signal strength of the infrared signal emitted by the lamp is equal to the preset value, and according to the signal strength of the infrared signal received by the infrared receiving module, the transmission power of the infrared emitting lamp whose signal strength is different from the preset value is adjusted so that the infrared signal emitted by the lamp is A processing module whose signal strength is equal to a preset value. The processing module adjusts the transmitting power of the infrared emitting lamp with a strong or weak infrared signal so that the signal strength of the emitted infrared signal is equal to the preset value, thereby improving the consistency of the emitted signal of the infrared emitting lamp and effectively solving the problem of Infrared touch screen mass production signal standardization problem, while improving the resolution of infrared touch screen, increasing its ability to resist sunlight interference.
Description
technical field [0001] The invention relates to the technical field of infrared touch, in particular to an adaptive infrared touch screen and a precision control method thereof. Background technique [0002] see figure 1 , most of the existing infrared touch screens use infrared emitting tubes 60 and infrared receiving tubes 70 installed around the touch panel 80, and they form mutually perpendicular infrared emitting and receiving arrays according to a one-to-one mapping relationship. The blocked energy value of the infrared beam between the receiving tubes is used to locate the position of the infrared touch point A. [0003] There are certain technical defects in the existing infrared touch screen, for example: because the infrared emitting lamp and the infrared receiving lamp are restricted by the production process level, it is difficult to achieve the same emission power, resulting in different infrared signal strengths from each infrared emitting lamp ( see figure...
