Description

[Technical field]

[0001] The present invention relates to the field of digital touch screen testing devices, and more particularly to a digital pen effective distance verification device for detecting whether the digital pen can maintain a qualified accuracy within the effective distance, and whether it can have functions such as line drawing indication at the operating distance. [Background technology]

[0002] With the popularization of various digital products, in order to operate more intuitively, most digital products use touch screens. This touch screen is formed by setting a transparent cover layer close to the display surface. The transparent cover layer detects the presence and position of input such as touch based on changes in the electrical characteristics of the cover layer. Currently, most touch screens are operated with fingers. However, using fingers to operate cannot accurately locate, and the delicate strokes of the drawing function cannot be used, so a pen-shaped digital pen is needed to form a handwriting-like operation.

[0003] The known digital pen adopts electromagnetic induction, which has a first power supply coil, a second power supply coil, an induction coil and an elastic component inside a pen-shaped shell. When the digital pen approaches the touch screen, the first power supply coil and the second power supply coil will sense the electromagnetic signal respectively, and convert it into DC power to supply the induction coil, and the induction coil generates and transmits the induction signal for the touch screen to receive the induction signal, so as to calculate the accurate coordinate position of the digital pen when touching, and execute the corresponding action command. When the above-mentioned action is continuous, continuous pen strokes are generated, and the thickness change amount can be controlled by the above-mentioned electromagnetic induction. In addition, there is also a digital pen design using conductive rubber, and a pen tip conductive rubber is provided at the front end. The thickness of the pen stroke is controlled by detecting the contact area between the pen tip conductive rubber and the touch screen. Whether it is electromagnetic induction or conductive rubber design, a longer stroke must be written to detect the change amount. Therefore, how to detect whether the digital pen can operate normally, the effective distance test reflects whether it can still have qualified accuracy when used at an appropriate distance, and has the functions of drawing and indicating at the operating distance.

[0004] Generally speaking, when testing most touch screens, it is required that the effective distance is within 15 mm to have normal cursor movement direction, trajectory and correct positioning without any abnormality. The basis for this is mostly that when drawing and drawing lines, there will be no line breakage. In the past, when testing, the digital pen was fixed at a height of 15 mm (or other specifications of 8 mm, etc.) on the touch screen, and then the digital pen was moved at a fixed height distance for plane movement test verification. Most of the time, the standard test height distance was guessed based on the tester's feeling. When the corner margins were not fixed, the cursor would be affected by the edge shell, and the pen tip would have a relatively large shake when moving, affecting the test results, so it was necessary to improve it. [Summary of the invention]
