Abstract

The present invention discloses an embedded touch screen, a display device and a driving method thereof. Touch control pressure induction electrodes which are disposed at an array substrate and face to a bottommost film layer at one side of an opposite substrate are added, a capacitor structure can be formed by the touch control pressure induction electrodes and a metal layer positioned below the array substrate, capacitance changes along with changes of distances between the touch control pressure induction electrodes and the metal layer when positions where the touch control pressure induction electrodes are pressed, so during a touch control time period, touch control positions can be determined by a touch control detection chip through detecting changes of capacitance values of touch control detection electrodes, and values of pressure at the touch control positions can be determined through detecting changes of capacitance values of the touch control pressure induction electrodes. The touch control pressure induction electrodes are integrated in a touch screen, a pressure induction function is fulfilled when touch control detection is carried out, the structure design of the display device is changed a little without being limited by assembling tolerance, and manufacturing cost is saved, thereby facilitating implementation of better detection precision.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to an embedded touch screen, a display device and a driving method thereof. Background technique [0002] Pressure sensing technology refers to the technology that can detect external force. This technology has been used in industrial control, medical and other fields a long time ago. At present, the way to achieve pressure sensing in the display field, especially in the field of mobile phones or tablets, is to add an additional mechanism to the backlight part of the LCD panel or the middle frame of the mobile phone. This design requires structural design of the LCD panel or mobile phone. changes, and the probing accuracy of this design is limited due to large assembly tolerances. [0003] Therefore, how to realize the pressure sensing with high detection accuracy with little modification of the display panel hardware is an urgent problem to be solved by those skilled in the art. ....
