Embodiment Construction

[0021] The present invention will be further described below in conjunction with embodiment:

[0022] A calibration method for a touch screen, comprising a test unit, a touch screen calibration program is pre-installed in the test unit; the touch screen to be tested is connected to the test unit;

[0023] The user checks whether the touch screen to be tested responds or responds slowly. If the test fails, you need to click the calibration icon on the test touch screen to exit the working mode and enter the calibration mode; thereby calibrate through the pre-installed touch screen calibration program;

[0024] Calibration is started by the user touching the touch screen to be tested, and the touch information during calibration is acquired by the acquisition module in the test unit for the touch coordinate value information on the touch screen to be tested; and the acquired touch coordinate value information is transmitted to the detection unit through the transmission unit dis...

Abstract

The invention discloses a calibration method for a touch screen, comprising a test unit, wherein a touch screen calibration program is pre-installed in the test unit; connecting the touch screen to betested with the test unit; whether the touch screen to be tested has any reaction or slow reaction is checked by the user. If the test is unqualified, clicking the calibration icon on the test touchscreen to exit the operation mode and enter the calibration mode; and if the test is unqualified, clicking the calibration icon on the test touch screen to enter the calibration mode. You need to seeif the touch coordinate value on the display matches the touch coordinate value on the test touchscreen, if there is a mismatch, the alarms will be displayed and the calibration parameters of the calibration algorithm will be modified. After modification, the touch screen will be checked manually again until the touch coordinate value on the display screen coincides with the touch coordinate valueon the test screen. The invention effectively calibrates the touch screen, and avoids the problems that the touch screen will not react or react slowly when the finger touches the screen after beinginfluenced by other factors.

Description

technical field [0001] The invention relates to a calibration method for a touch screen. Background technique [0002] In the existing market, the touch screen has basically replaced the mechanical button type. The tactile feedback system of the existing touch screen can drive various connecting devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create a vivid display through the LCD screen. It is currently the simplest, most convenient and natural way of human-computer interaction. However, when the existing touch screen is affected by other factors, there will be problems such as no response or slow response when the finger touches the screen. [0003] Therefore, those skilled in the art are committed to developing a calibration method for the touch screen that can effectively avoid problems such as no response or slow response when the touch screen is touched by a finger due to other factors.
