Embodiment 1

[0059] The touch screen calibration system provided in this embodiment includes a positioning and clicking device, and the positioning and clicking device is as follows: figure 1 Shown, including calibration controller, robotic arm, and stylus. The mechanical arm can be an existing three-axis driven mechanical arm capable of moving in the X, Y, and Z axes. The calibration controller controls the mechanical arm to drive the touch pen to move above the display screen under test. After precise positioning Use the center of the stylus to click the center of the coordinate point (also called the calibration point) displayed on the display screen under test, such as the center point of the cross coordinate point and the center of the circular coordinate point; the operator can control the machine through the calibration controller The arm, or the calibration controller can capture the position image of the center of the calibration point through an external camera, calculate the off...

Embodiment 2

[0062] In this embodiment, the calibration controller not only can control the positioning and clicking of the touch pen on the mechanical arm, but also has the calibration function of the touch screen.

[0063] Such as image 3 As shown, the calibration controller in the touch screen calibration system in this embodiment not only controls the connection with the mechanical arm, but also has a port for connecting the touch screen under test and the display screen under test, which is used to directly communicate with the touch screen under test and the display screen. The calibration controller can typically use a computer to connect to the touch screen under test through a connection port such as USB or COM, and to connect and control the display screen under test through interfaces such as VGA, HDMI, and DVI. The storage of the calibration controller The calibration algorithm and I calibration point coordinates (I is an integer greater than or equal to 1) required by the cal...

Abstract

The invention relates to a positioning clicking device and method and a touch display screen calibration system and method. The positioning clicking device automatically controls a mechanical arm to drive a touch pen to click the center of a calibration point displayed on a display screen to be tested through a calibration controller, and the whole positioning clicking process is automatic, needs no manual intervention and is high in execution efficiency. In addition, compared with manual operation, the positioning clicking device has higher accuracy in calibration point clicking. Therefore, by adopting the calibration system comprising the positioning clicking device and the touch display screen calibration method by using the calibration system, accurate touch point coordinates and calibration parameters can be obtained, errors of a display zone and a touch zone caused by mechanical assembling are removed by aid of the calibration system, touch accuracy is improved, and mistaken touch is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a positioning and clicking device and method for calibrating a touch screen, and a system and method for calibrating a touch screen. Background technique [0002] As a mature human-computer interaction device, touch screen has been widely used in many fields. Compared with traditional keyboard and mouse input methods, touch screen input is more intuitive. With recognition software, the touch screen can also realize handwriting input. It has the characteristics of quickness, flexibility, high resolution and long service life. The touch screen can be used as a simulated keyboard, which is more flexible than a common keyboard and saves the space occupied by the keyboard, so the touch screen can be used in a wide range of applications. Existing touch screen products mainly include resistive touch screens, capacitive touch screens, surface acoustic wave touch screens, and inf...
