32 inch touch screen tv.However, in actual applications, the light intensity signals in these two states will be affected by external light to varying degrees. For at " 0 " state, all of the infrared emission is not illuminated, but a to the conversion of the interfering ambient light, received not 0 , on to " 1 emitting" state, infrared tube lit one by one , made in the presence of interfering external light, so that the infrared receiver is receiving external light and the light intensity signal corresponding to the reception signals received pipe launch tube. At the same time, during the entire scanning process , the external light changes in real time. In this way, the data collected at different times may be compared with the first obtained domain values, which may cause incorrect touch judgment and cause misoperation of the touch screen. These factors cause the infrared touch screen to judge the touch position normally and correctly.
