Method and device for calibrating touch screen

Abstract

The invention discloses a method for calibrating a touch screen. The method comprises the following steps of: (1) after terminal equipment is started up, searching whether a calibrating data file exists, performing a step (2) if the calibrating data file does not exist, otherwise, performing a step (4); (2) after startup is finished, automatically launching a touch screen calibrating program, prompting a user to perform touch screen calibration, and reading calibrating data from a hardware processing unit by using a touch screen driving program after calibration is finished; (3) generating a calibrating data file according to the calibrating data read from the hardware processing unit; and (4) writing the calibrating data in the calibrating data file into the hardware processing unit. If the user finds that the touch screen works abnormally, the touch screen calibrating program is started to recalibrate the touch screen. The method has the advantages that the calibrated touch screen calibrating data are saved in a calibrating data file, and calibration is not required to be performed at certain time intervals or during each wake-up of a mobile phone.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a touch screen calibration method and device. Background technique [0002] Along with increasing with each passing day of multimedia information inquiry, the application of touch screen is more and more common. Because the touch screen is a new type of computer input device, it is one of the simple, convenient and natural human-computer interaction methods. Using the touch screen technology, the user only needs to touch the icon or Text can realize the operation of electronic equipment, so that the human-computer interaction is more straightforward. At present, such products need to be calibrated before normal use to ensure the accuracy of the product in the current environment (environment includes: climate, weather, electromagnetic and other external interference). Accuracy refers to the difference between the operating area and the operating function. Corresp...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a touch screen calibration method and device, which solves the problem that in the prior art, when the touch screen is calibrated, it is time-consuming and takes up system resources, which has a certain impact on the use of the user. If there is water on the screen, it will be slow to dry and recover, and sometimes it cannot be recovered; or use calibration every time the phone wakes up, if there is water on the touch screen before waking up, the water will be calibrated to the reference parameters, and the user will adjust the water After drying, the touch screen cannot be used, and can only be re-slept and woken up again, which brings great inconvenience to users
