Embodiment Construction

[0034] Embodiments of the present invention provide an in-cell touch screen and a display device, which are used to solve the problem of mutual interference between touch signals and image display signals, and at the same time increase the aperture ratio of the in-cell touch screen.

[0035] In the in-cell touch screen provided by the embodiment of the present invention, every two rows of adjacent sub-pixel units are a sub-pixel unit group, and two gate lines are arranged between the two rows of adjacent sub-pixel units, and the two rows The gate lines respectively provide gate signals for the two rows of sub-pixel units; the touch driving electrodes are located between adjacent groups of sub-pixel units. The grid lines and the touch drive electrodes are located in different areas on the array substrate without vertically overlapping surfaces, and the touch drive signals of the touch drive electrodes do not affect the gate scan signals of the gate lines, thereby avoiding the in...

Abstract

The invention discloses a built-in touch screen and a display device. The built-in touch screen and the display device are used for solving the problem that mutual interference exists between a touch control signal and an image display signal and meanwhile, improving an aperture ratio of the built-in touch screen. The built-in touch screen comprises a colored membrane substrate arranged opposite to a box and an array substrate. Multiple sub pixel units arranged in a matrix mode are arranged on the array substrate. The built-in touch screen further comprises multiple touch inductance electrodes which are arranged on the colored membrane substrate in the column direction of the sub pixel units and multiple touch drive electrodes which are arranged on the array substrate in the row direction of the sub pixel units. A sub pixel unit set is formed by every two adjacent rows of sub pixel units. Two grid lines which provide grid signals for the two adjacent rows of sub pixel units receptively are arranged between the two adjacent rows of sub pixel units. The touch drive electrodes are arranged on non-display zones among the sub pixel unit sets.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to an embedded touch screen and a display device. Background technique [0002] The in-cell touch panel (In cell Touch Panel) is a device that integrates a touch screen and a display screen. The touch driving electrodes and the touch sensing electrodes are integrated in the display screen to realize the functions of touch control and image display at the same time. Due to the characteristics of simple structure, lightness, thinness and low cost, the embedded touch screen has gradually become the mainstream in the display field. [0003] see figure 1 , for the touch driving electrodes 800 arranged horizontally and the touch sensing electrodes 900 arranged vertically, the coupling between adjacent touch driving electrodes 800 and touch sensing electrodes 900 generates an interaction capacitance C m (mutual capacitance), when a finger touches the screen, the touch of the finge...
