Abstract

The invention discloses an embedded type touch screen, a driving method thereof and a display device. The embedded type touch screen can be subjected to touch control under the condition that the pixel aperture ratio is not influenced. The embedded type touch screen comprises a plurality of touch control electrodes and a shading structure; the shading structure comprises a plurality of first shading strips parallel to a first direction and a plurality of second shading strips parallel to a second direction; the first direction is vertical to the second direction; the first shading strips have conductivity; the touch control electrodes are in one-to-one correspondence and electric connection with the first shading strips, respectively.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an embedded touch screen, a driving method thereof, and a display device. Background technique [0002] With the rapid development of display technology, touch screens (TouchScreenPanel) have gradually spread in people's lives. At present, touch screens can be divided into three types according to their composition structures: Add-on Mode Touch Panel, OnCell Touch Panel, and InCell Touch Panel. Among them, the plug-in touch screen is produced separately from the touch screen and the Liquid Crystal Display (LCD), and then bonded together to form a liquid crystal display with touch function. The plug-in touch screen has high production costs, low light transmittance, The module is thicker and other shortcomings. The embedded touch screen embeds the touch electrodes of the touch screen inside the liquid crystal display, which can reduce the overall thickness of the module and gre...
