Embodiment Construction

[0042] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0043] The present invention aims at the technical problems of the existing flexible touch panel, where the contact area between the two ends of the conductive bridge and the electrodes is small, which may easily cause high connection impedance or risk of open circuit, and this embodiment can solve this defect.

[0044] Such as image 3 As shown, the flexible touch pa...

Abstract

The invention provides a flexible touch panel. The panel includes a first conductive pattern layer, an insulated layer and a second conductive pattern layer. The first conductive pattern layer comprises first driving electrode patterns and first sensing electrode patterns, wherein the first driving electrode patterns are successively connected with one another in a first direction; the insulated layer is arranged on the first conductive pattern layer, and metal through holes are formed in the surface of the insulated layer; the second conductive pattern layer is arranged on the insulated layer; the second conductive pattern layer consists of second driving electrode patterns and second sensing electrode patterns; the second sensing electrode patterns are successively connected with one another in a second direction; the first driving electrode patterns and the second driving electrode patterns are connected through the corresponding metal through holes; the first sensing electrode patterns and the second sensing electrode patterns are connected through the corresponding metal through holes. The provided flexible touch panel has the advantages that by arranging two layers of touch electrodes, the two layers of touch electrodes are correspondingly and electrically connected in order to replace an electrical connection design of conductive bridges, and the technical problems, suchas high impedance and an open circuit, which are caused by connection of the conductive bridges are avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible touch panel and a flexible OLED display panel. Background technique [0002] Organic light-emitting diodes (OLEDs) have the characteristics of self-luminescence, fast response speed, wide viewing angle, etc., and have broad application prospects. Today, bendable displays are mainstream. [0003] With the rapid development of flexible OLED display panel technology, the matching touch panel is also required to be flexible and flexible. The touch line of the traditional touch screen is made of ITO (Indium tin oxide, indium tin oxide) material, but ITO is The brittle metal oxide material is easy to break when bent, which cannot meet the requirements of flexible touch. [0004] Metal Mesh (metal grid) is suitable for use on flexible touch screens due to its good flexibility; figure 1 , figure 2 As shown, in the traditional touch screen, the touch screen needs to be ma...
