Abstract

The invention discloses an embedded type touch screen which has the characteristics of simple structure and lower cost. The embedded type touch screen comprises a first substrate and a second substrate which are arranged oppositely, a plurality of transversely-arranged touch driving lines, a plurality of longitudinally-arranged touch induction lines, and a plurality of touch control scanning TFTs (thin film transistor), wherein a plurality of gird lines are transversely formed on the first substrate; the grid of each touch control scanning TFT is connected with one grid line; and the grid line is only connected with the grid of one touch control scanning TFT; the source of each touch control scanning TFT is connected with a touch driving circuit; the drain of each touch control scanning TFT is connected with one touch driving line; and the number of the touch control scanning TFTs is not less than that of the grid lines and not more than that of the touch driving lines.

Description

technical field

[0001] The invention relates to the technical field of touch display, in particular to an embedded touch screen. Background technique

[0002] As an input medium, a touch panel forms a touch display screen together with a display screen, and the touch display screen has gradually become the mainstream in the display field.

[0003] Currently, the most widely used touch screens are Add on Touch Panel which is hung outside the display screen and In cell Touch Panel which is embedded in the display screen. The external touch screen display is produced separately from the touch screen, and then bonded together to form a touch display with touch and display functions.

[0004] With the continuous improvement of optical and electrical characteristics required by flat panel displays, and consumer demand for thinner flat panel displays, high performance, low cost, ultra-thin Touch display has gradually become the main goal pursued by major manufacturers. The exist...
