Embedded touch liquid crystal display device

Abstract

The invention provides an embedded touch liquid crystal display device. The embedded touch liquid crystal display device comprises a plurality of gate lines located on a first substrate, a plurality of data lines located on the first substrate and staggered with the plurality of gate lines, a plurality of touch signal lines located on the first substrate, a plurality of thin film transistors located on the first substrate and electrically connected with the plurality of gate lines and the plurality of data lines, a plurality of pixel electrodes electrically connected to the plurality of thin film transistors, a plurality of shared electrodes overlapping with the plurality of pixel electrodes and electrically connected with the plurality of touch signal lines, a first insulating layer located between the plurality of shared electrodes and the plurality of pixel electrodes, a second substrate arranged opposite to the first substrate, and a display medium located between the first substrate and the second substrate, wherein each touch signal line is located between two adjacent data lines. The embedded touch liquid crystal display device is low in cost and good in performance.

Description

technical field [0001] The present invention relates to a touch liquid crystal display device, in particular to an embedded touch liquid crystal display device. Background technique [0002] In-cell touch display devices have the advantage of being thinner, so they have always been the technical goal of panel manufacturers entering the field of touch products. By embedding the touch detection components in the stacked structure of the display panel, the display panel can simultaneously have the functions of image display and touch detection, so as to provide more competitive product types. [0003] The existing in-cell touch display device includes a display panel and a touch detection component integrated in the display panel. Generally speaking, an additional photomask is required to integrate the touch detection component into the display panel to complete the touch electrodes and touch signal lines, which will increase the difficulty and cost of the manufacturing proces...

Problems solved by technology

Generally speaking, an additional photomask is required to integrate the touch detection components into the display panel to complete the touch electrodes and touch signal lines, which will increase the difficulty and cost of the manufacturing process

In addition, when the display panel and the touch detection component are integrated with each other, there will be too many wires to interfere with each other, and the aperture ratio will be affected.
