Accordingly, the invention also provides a touch display device provided with the touch display panel.

The invention relates to the technical field of conductive glass, and discloses a method for machining a piece of double-sided coated glass for a capacitive screen and the double-sided coated glass. The double-sided coated glass is characterized in that a transparent conductive film I is arranged on a transparent passivation layer on a tin surface of a glass substrate; and a transparent conductive film II is arranged on a disapparation layer on an air surface. The machining method comprises the following steps of: firstly processing an original glass substrate, sputtering the disapparation layer (6) and the transparent passivation layer (4) onto the glass substrate, and then sputtering an indium tin oxide conductive film respectively on the transparent dissapparation layer and the transparent passivation layer of the glass substrate. Due to the adoption of the method, an indium tin oxide conductive film etching circuit can be prevented from being etched by an acid solution in a production process, and a good electromagnetic shielding, electrostatic protection or disapparation effect can be realized. The double-sided coated glass can completely substitute traditional conductive glass, the double-sided coated glass for the capacitive screen, which is low in energy consumption, high in uniformity and low in cost, can be provided for downstream customers.

The invention discloses a bridging-free projection type capacitive screen and a manufacturing method of the bridging-free projection type capacitive screen. The bridging-free projection type capacitive screen comprises a glass substrate, a first shadow eliminating layer arranged on the glass substrate, a first ITO layer arranged on the first shadow eliminating layer, a second shadow eliminating layer arranged on the first ITO layer and a second ITO layer arranged on the second shadow eliminating layer. The first ITO layer comprises an X-axis electrode layer formed by a plurality of electrodes in the X-axis direction. The second ITO layer comprises a Y-axis electrode layer formed by a plurality of electrodes in the Y-axis direction. The bridging-free projection type capacitive screen further comprises metal wires X arranged on the edges of the X-axis electrode layer and metal wires Y arranged on the edges of the Y-axis electrode layer. The metal wires X and the metal wires Y are connected with a flexible circuit board respectively. The bridging-free projection type capacitive screen is light and thin in structure, good in shadow eliminating effect and beneficial for saving manufacturing processes since the bridging process is not needed in the manufacturing process.
