Problems solved by technology

However, due to the same technical principle, it cannot guarantee the same sampling data for each touch of the same point, and cannot guarantee absolute coordinate positioning, and the point is not accurate. This is the most feared problem of the touch screen: drift
In actual production, due to the inconsistency of the sensor and the inconsistency of the equipment assembly, there will be a certain deviation between the sensitivity and the preset parameters, which will affect the linearity or sensitivity of the detection.

Abstract

The invention provides a touch screen coordinate calibration device, which is used for calibrating a touch screen and comprises a support. The support is arranged above the touch screen, a plurality of styluses are arranged on the support at intervals, nibs of the styluses can stretch to the touch screen, slide rails are arranged above the styluses and extend along track directions of the styluses, sliders are arranged in the slide rails, and slide along the track directions of the styluses, a plurality of pressure-control switches are disposed on the support, and correspond to the styluses one by one, and after one slider presses the corresponding pressure-control switch, the nib of the corresponding stylus extends out and clicks on the touch screen. The styluses are guided to click by the aid of pressing states among the sliders and the pressure-control switches, and the touch screen coordinate calibration device is high-efficiency, convenient and speedy in operation.

Description

【Technical field】 [0001] The invention relates to a coordinate calibration device, in particular to an efficient and convenient touch screen coordinate calibration device. 【Background technique】 [0002] Different from the mouse coordinate positioning method, the touch screen is an absolute coordinate system, where you want to choose, just click directly, which is fundamentally different from the relative positioning system. The characteristic of the absolute coordinate system is that each positioning coordinate has nothing to do with the previous positioning coordinates. The data of each touch is converted to the coordinates on the screen through calibration. No matter what the situation is, the output data of the coordinates of the touch screen at the same point is stable. of. However, for the same reasons as the technical principle, it cannot guarantee the same sampling data every time the same point is touched, and the absolute coordinate positioning cannot be guarantee...
