Problems solved by technology

[0003] However, in the infrared touch screen device, each pair of infrared emitting elements and infrared receiving elements are paired. Due to many reasons such as production technology, the optical axis of the infrared emitting element and the optical axis of the infrared receiving element may have a certain deviation angle. So that the infrared receiving element can only receive little or even no infrared light emitted by the emitting element, it is necessary to manually correct the angle between the optical axis of the infrared emitting element and the infrared receiving element,

Embodiment 1

[0026] As shown in FIG. 2, it is a schematic flowchart of Embodiment 1 of the debugging method of the touch screen device of the present invention. In this embodiment, when debugging, only the gain multiple of the receiving circuit corresponding to the receiving element is modified.

[0027] As shown in the figure, it includes the steps:

[0028] Step S201: Start an infrared scan to detect the intensity value of the infrared signal received by the infrared receiving element, which is called the detection value, and go to step S202;

[0029] Step S202: Determine whether the detection value is greater than or equal to the minimum predetermined value and less than or equal to the maximum predetermined value, that is, whether the minimum predetermined value <= the detection value <= the maximum predetermined value is satisfied, if not, go to step S203, if yes, Then there is no need to debug or complete the debugging of the relevant device parameters corresponding to the current infrar...

Embodiment 2

[0045] As shown in FIG. 3, it is a schematic flowchart of the second embodiment of the debugging method of the touch screen device of the present invention. In this embodiment, when debugging, only the pulse width of the transmitting circuit corresponding to the transmitting element is adjusted.

[0046] As shown in the figure, it includes the steps:

[0047] Step S301: Start an infrared scan to detect the intensity value of the infrared signal received by the infrared receiving element, which is called the detection value, and go to step S302;

[0048] Step S302: Determine whether the detection value is greater than or equal to the minimum predetermined value and less than or equal to the maximum predetermined value, that is, whether the minimum predetermined value <= the detection value <= the maximum predetermined value is satisfied, if not, go to step S303, if yes, Then there is no need to debug or complete the debugging of the relevant device parameters corresponding to the c...

Embodiment 3

[0066] There are many reasons why the signal strength received by the infrared receiving element is outside the optimal range. For example, the aging of the transmitting element causes the intensity of the infrared signal emitted under the same pulse width to become lower, and the aging of the receiving element causes the receiving sensitivity to decrease, As well as some other external factors such as dust occlusion, etc., therefore, in this embodiment, the pulse width of the transmitting circuit corresponding to the infrared emitting element and the gain multiple of the receiving circuit corresponding to the infrared receiving element are adjusted simultaneously. Elaboration.

[0067] As shown in the figure, in this embodiment, it includes the steps:

[0068] Step S401: Start an infrared scan to detect the intensity value of the infrared signal received by the infrared receiving element, which is called the detection value, and go to step S402;

[0069] Step S402: Determine whet...

Abstract

The invention discloses a debugging method of touch screen and a relative touch screen. The method comprise starting infrared scanning to detect the detected value of infrared signal strength received by an infrared receiver, when the detected value is outside the best range, adjusting the device parameters of an infrared scanning module, when the detected value is in the best range, eliminating the adjustment. The invention starts infrared scanning and judges the infrared signal strength received by the infrared receiver, which eliminates the adjustment on the infrared emitter-receiver when the received infrared signal strength is in a preset range, and directly judges the debugging end on the infrared emitter-receiver, and adjusts the device parameters of the infrared scanning module when the received infrared signal strength is in the preset range. The invention can debug with hand operation, with simple maintenance and debugging to save debugging cost.
