Abstract

The invention belongs to the technical field of touch screens and discloses a writable mobile terminal and a touch screen. The touch screen comprises a touch layer as well as a first conducting layer and a second conducting layer which are arranged at the same side of the touch screen, wherein an isolation point is arranged between the first conducting layer and the second conducting layer; the touch layer is used for receiving the touch action of a user; and a first coating area and a second coating area are respectively arranged on the first conducting layer and the second conducting layer and provided with conducting materials. Because the coating areas are respectively arranged on the two conducting layers of the touch screen and can be in parallel-arrangement strip shape, and the conducting materials are arranged on the coating areas, the touch screen can directly judge according to the inductions of the coating areas when the touch action happens, therefore, the cost of the touch screen is greatly reduced, the calibration rate of the touch screen is also improved, and the writable mobile terminal is beneficial to the development of a touch screen technique.

Description

technical field

[0001] The invention belongs to the technical field of touch screens, and in particular relates to a mobile terminal capable of handwriting and a touch screen. Background technique

[0002] With the continuous popularization of mobile terminals capable of handwriting, users have higher and higher requirements for functions of mobile terminals capable of handwriting.

[0003] Take a mobile phone that can be written by hand as an example. At present, the commonly used touch button technologies in mobile phones generally include resistive and capacitive types.

[0004] In the prior art, the design of resistive touch keys adopts the method of resistive analog quantity to read the divided voltage values ​​of the X and Y axes at different positions, and transmits the analog-to-digital conversion (Analog-to-Digital Converter, ADC) module of the touch control IC to realize Positioning, it is easy to produce certain errors. If interference is introduced into the tran...
