Embodiment Construction

[0030] Such as Figure 3-5 As shown, it is a preferred embodiment of the etching method of the indium tin oxide film in the gap part of the capacitive touch panel of the present invention.

[0031] The insulating transparent substrate of the capacitive touch panel is provided with an indium tin oxide film (ITO), which includes a display area 1 and a gap area 2, such as image 3 As shown, the display area 1 and the gap area 2 are distributed alternately, and the range of the width of the gap area 2 is generally [0.2mm, 0.3mm] limited by the requirements of the control chip. In this embodiment, The width of the gap region 2 is preferably 0.3 mm.

[0032] When etching the ITO of the gap region 2, the ITO of the gap portion 2 is divided into several ITO segments 5 by laser etching lines, as Figure 4 As shown, each of the ITO segments 5 is independent and not connected to each other, that is, there is an interval 6 between adjacent ITO segments 5, and the length of the interval ...

Abstract

An etching method for a capacitive touch panel and its gap part of an indium tin oxide film, comprising dividing the ITO in the gap part into several ITO segments by using laser etching lines, and each of the ITO segments is independent of each other and not connected to each other. The etching method of the capacitive touch panel and the gap portion of the indium tin oxide thin film of the present invention has high production efficiency, and the etched touch screen product has good display effect.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a capacitive touch panel and an etching method for an indium tin oxide film in a gap part thereof. Background technique [0002] The existing capacitive touch screen mainly includes a capacitive touch panel and a flexible circuit board, and the flexible circuit board is covered with a cover plate. Wherein, the capacitive touch panel is referred to as sensor for short, and includes an insulating transparent substrate, a sensing circuit layer and a driving circuit layer. Wherein, the insulating transparent substrate is selected from one of glass or plastic film; the sensing line layer is a light-transmitting conductive film or glass with a sensing line; the driving line layer is a light-transmitting conductive film or glass with a driving line, and the driving The circuit layer and the induction circuit layer are respectively stacked on both sides of the insulating tra...
