Abstract

The invention discloses a touch sensor and a manufacturing method thereof, and a touch screen liquid crystal display. The touch sensor comprises: a substrate, a touch inductive layer in the first direction, a touch inductive layer in the second direction that perpendicular to the first direction, insulating layers and a metal bridge. The characteristics of the touch sensor lie in that, the touch inductive layer in the first direction and the touch inductive layer in the second direction are positioned on the surface of the substrate, and the touch inductive layer in the first direction is disconnected; the insulating layers are positioned on the substrate, and surfaces of the touch inductive layer in the first direction and the touch inductive layer in the second direction; the metal bridge is connected with the touch inductive layer in the first direction, and positioned on the surface of the insulating layer. According to the invention, the touch sensor can be produced by carrying out three composition technologies on three mask plates. Accordingly, production process of the touch sensor is simplified, and production cost is lowered.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal displays, in particular to a touch sensor, a manufacturing method thereof, and a touch screen liquid crystal display. Background technique

[0002] In recent years, the touch panel (Touch Panel) liquid crystal display has developed rapidly, and has developed into a mainstream flat panel display. According to the structure, the touch screen LCD is mainly divided into three types: Add On Mode Touch Panel, On Cell Touch Panel and In Cell Touch Panel.

[0003] figure 1 The touch sensor (Touch Sensor) of the plug-in touch screen in the prior art is shown, as figure 1 As shown, the touch sensor includes: a substrate 1, a metal bridge 2, a first insulating layer 3, a touch sensing layer 4 in the X direction, a touch sensing layer 4' in the Y direction, and a second insulating layer 5; The touch sensing layer 4 is connected through the metal bridge 2 so as to be conducted. In addition, an upper...
