Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] FIG. 2 is a flow chart showing the touch screen noise filtering method of the present invention. As shown in the figure, the position information input by the user is continuously detected by the touch panel control unit for a certain number of times, and the average value thereof is calculated.

[0016] Afterwards, compare the position information of the above-mentioned detection with the average value, remove the data that has a large gap with the average value, and calculate the average value of the remaining data, so that this value can be used as one data.

[0017] As mentioned above, the touch screen samples the location information at a certain time interval, and averages a certain amount of sampled data, which is used as the final location information data. However, in order to solve the problem that the position information that should b...

Abstract

Said invention refers to method for filtering noises of touch control screen. It contains finding out mean value after detecting positional information, comparing above-mentioned positional information and mean value, calculating difference, outputting final position message.

Description

【Technical field】 [0001] The present invention is an invention related to a noise filtering method of a touch screen. In particular, when the user keeps pressing a point on the touch screen, it can improve the hardware noise or technical limitations caused by the digital conversion of the touch position to analog data. The invention relates to the touch screen noise filtering method of the mouse point jitter phenomenon on the screen. 【Background technique】 [0002] Generally speaking, the touch screen is the simplest and most direct way for people to communicate with computers. Because of the combination of input devices and display devices, there is no need for input devices such as a mouse or a keyboard, and users can also touch what is required by the user on the screen. Parts, making it move, has the advantages of intuition and convenience for children or the elderly who do not understand computer operations. [0003] A touch screen with the above characteristics such a...
