Embodiment Construction

[0029] Such as figure 2 As shown, the capacitive whiteboard touch film structure of the present invention includes an insulating film, and the insulating film is divided into at least two adjacent insulating regions in sequence, one of which is set as the first insulating region, and laying along the same insulating region in each insulating region The same number of wires in the same direction, the wires in the first insulation area are connected to the PCB board through lead-out lines, and the wires in other insulation areas are respectively connected to a wire in the first insulation area through jumper wires. According to an embodiment of the present invention, the wires in different insulating regions are arranged in the same direction. The wires in each of the insulating regions are arranged at equal intervals along the vertical direction. The jumpers are arranged at equal intervals along the horizontal direction. The first insulating region is disposed on the left en...

Abstract

The invention discloses a capacitive whiteboard touch film structure and a touch signal processing method. The touch film structure comprises an insulating film. The insulating film is divided into atleast two insulating regions which are adjacent in sequence; one insulation area is set as a first insulation area, the same number of wires in the same direction are laid in each insulation area, the wires in the first insulation areas are connected to the PCB through outgoing lines, and the wires in the other insulation areas are sequentially connected with one wire in the first insulation areathrough overlines. The touch signal processing method comprises the following steps: receiving a touch signal; determining the position and size information of the touch point, judging the number andconcentration of the touch points of all the touch signals, setting a touch point threshold value, and removing the touch signals which do not meet the touch point threshold value; carrying out signal characteristic judgment on the rest touch signals, and eliminating the touch signals which do not meet the signal characteristics; carrying out signal suppression on the eliminated touch signal; andobtaining real touch point information.

Description

technical field [0001] The invention relates to the technical field of capacitive whiteboards, in particular to a touch film structure and a touch signal processing method of a capacitive whiteboard. Background technique [0002] The touch control structure of the capacitive whiteboard in the prior art is that a number of wires along the horizontal direction are arranged on one side of an insulating layer, and a number of wires along the vertical direction are arranged on the other side of the insulating layer. All wires need to be connected to the PCB board through lead wires, such as figure 1 As shown, this structure needs to lay dozens of PCB boards around the capacitive whiteboard, and connect the leads of the wires to the PCB board. Therefore, the processing technology of the touch structure is very complicated and the manufacturing cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a capacitive ...
