Calibration device that can calibrate the screens of two mobile phones at the same time

Abstract

The invention discloses a calibrating device capable of simultaneously calibrating two mobile phone screens. The calibrating device comprises a U-shaped base, a cover plate arranged at the upper end of the U-shaped base, mobile phone positioning devices arranged at the bottom of the U-shaped base, and touch pen adjusting devices arranged on the cover plate, wherein two groups of the mobile phone positioning devices and two groups of the touch pen adjusting devices are symmetrically arranged on the U-shaped base. According to the invention, mobile phones are fixed through the U-shaped base and the positioning devices, and the screen calibration points of the mobile phones directly face the touch pens after the mobile phones are mounted on the positioning devices, so that the calibration accuracy is high, and misoperation is avoided; structures such as guide grooves, sliding rails and guide blocks are arranged, and positions of front positioning plates and right positioning plates in the positioning devices can be adjusted, therefore screen calibration can be performed on mobile phones with different sizes and different calibration positions; both the mobile phone positioning devices and the touch pen adjusting devices have two groups, two mobile phones can be calibrated at the same time, and the working efficiency is higher.

Description

technical field [0001] The invention relates to a tool, in particular to a mobile phone screen calibration tool. Background technique [0002] The touch screen of a mobile phone is an absolute coordinate system, which is essentially 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, due to technical reasons, it cannot guarantee the same sampling data every time the same point is touched, and the absolute coordinate positioning cannot be guaranteed, and the point is not accurate. This is the most feared problem of the touch screen: drift. [0003] More and more mobile phone products use display screens with touch ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide a calibration device that can calibrate the screens of two mobile phones at the same time, so as to solve the problems in the prior art that manual calibration of mobile phone screens with a touch pen is less efficient and prone to misoperation
