The present invention relates to an embedded touch sensitive display, which includes a liquid crystal display (LCD), a touch sensing layer, a touch signal transfer circuit and a conductive media. The liquid crystal display comprises a top substrate, a bottom substrate, and a liquid crystal layer which is configured between the top substrate and the bottom substrate. The touch sensing layer is disposed below the top substrate of the LCD for generating touch signals after sensing an outside touch action, and the touch signal transfer circuit is disposed above the bottom substrate of the LCD. The conductive media is disposed between the touch sensing layer and the touch signal transfer circuit for transferring the touch signals between the touch sensing layer and the touch signal transfer circuit.

The upper transparent conductive layer, the upper transparent plate, the circuit unit and the upper polarizing plate are disposed on the liquid crystal layer in the above-mentioned order from one side of the liquid crystal layer. The lower transparent conductive layer, the lower transparent plate and the lower polarizing plate are disposed under the liquid crystal layer in the above-mentioned order from another side of the liquid crystal layer.

Touch screen

Disclosed are a capacitive touch control device and a method thereof. A top face of a substrate is provided with first and second electrode groups, which each include a plurality of strip-like electrodes spaced from each other by a preset distance. The electrodes of the first and second electrode groups are respectively connected by first and second group scanning lines to a scanning circuit. When the first group scanning lines drive the electrodes of the first electrode group, the second group scanning lines carry out scanning operation on the electrodes of the second electrode group, and when the second group scanning lines drive the electrodes of the second electrode group, the first group scanning lines carry out scanning operation on the electrodes of the first electrode group. And, a touch location can thus be determined by using a microprocessor.

Capacitive touch control device and method thereof

A method of forming double-sided patterns in a touch panel circuit is disclosed. A first conductive layer and a second conductive layer are respectively formed on both sides of a substrate. A blocking layer is formed on a top surface of the first conductive layer for blocking ultraviolet (UV) light. A first photoresist layer is formed on a top surface of the blocking layer, and a second photoresist layer is formed on a bottom surface of the second conductive layer. Accordingly, two sides of the substrate may be exposed, developed and etched at the same time, thereby substantially simplifying the process of manufacturing the touch panel circuit.

Method of forming double-sided patterns in a touch panel circuit

A method of forming a touch sensing circuit pattern includes steps of: forming a first axial conductive line on a transparent substrate; forming an insulation barrier on the first axial conductive line; forming two separated first axial electrodes, two separated second axial electrodes and the second axial conductive line on the transparent substrate. The first axial electrodes are arranged on two sides of the insulation barrier along a first direction. The second axial electrodes are arranged on two opposite sides of the axial conductive line along a second direction. The second axial conductive line is across on the insulation barrier and connects to the second axial electrodes. The method of the invention can simplify the manufacturing process.
