Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like image 3 As shown, it is a schematic structural diagram of a touch screen according to an embodiment of the present invention. The touch screen embeds touch electrodes in the display panel 100 , and the touch electrodes include touch signal input electrodes and touch signal output electrodes arranged in cross-insulation. The display panel 100 includes a data line 102, a gate line 103 and a first common electrode 101, the gate line 103 and the data line 102 define a plurality of pixel units, each pixel unit is provided with a pixel electrode, the first common electrode 101 A common electrode 101 is divided into a plurality of regions at least along the data line direction, each region of the first common electrode correspon...

Abstract

The present disclosure discloses a touch screen and a driving method therefore. The touch screen embeds touch control electrodes in a display panel, the touch control electrodes includes touch control signal input electrodes and touch control signal output electrodes which are cross-insulated configured, the first common electrodes are divided into a plurality of areas at least along a direction of the data lines, each area of the first common electrodes corresponds to at least one row of pixel units; the areas of first common electrodes are insulated from each other and used as the touch control signal input electrodes. The touch screen according to the present disclosure divides the common electrodes into a plurality of areas along a direction of the data lines, and uses the areas as touch control signal input electrodes. The present disclosure uses a voltage disturbance generated by common electrodes used as driving electrodes to balance out a reduction of pixel voltage, thereby disturbance impact brought by a scan of the common electrodes is reduced and the quality of the picture is improved.

Description

technical field [0001] The present invention relates to the field of touch screens, in particular to a touch screen and a driving method thereof. Background technique [0002] As an input medium, the touch panel (TP) is integrated with the display screen as a touch screen, and the touch screen plays an important role in the display field. [0003] Among them, the capacitive touch screen has attracted much attention because of its high sensitivity. The mutual capacitive touch screen is favored by people because of its high sensitivity and the advantages of multi-touch. Capacitive touch screens include: external touch screens and in-cell touch screens. The in-cell touch screen is a touch screen that integrates TP into a liquid crystal display panel (Liquid Crystal Display, LCD). The in-cell touch screen has become a research hotspot due to its low production cost, good light transmittance and thin module thickness. [0004] The basic working principle of the mutual capacit...
