Flexible touch display panel

Abstract

The invention provides A flexible touch display panel including a touch electrode layer made of a transparent conductive material, the touch electrode layer includes a plurality of first touch electrodes arranged in a first direction and a plurality of second touch electrodes arranged in a second direction and insulated from the first touch electrode, the flexible touch display panel is divided into a bending area and a first display area and a second display area on both sides of the bending area, the first touch electrode and the second touch electrode of the touch electrode layer are hollowed out integrally or partially in the bent region compared to those in the first display region and the second display region, so as to enhance the bending resistance of the touch electrode layer in the bending region, reduce the risk of crack and fracture of the touch electrode in bending, and further reduce the risk of losing the touch function of the display panel.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a flexible touch display panel. Background technique [0002] In flat panel display technology, organic light-emitting diode (Organic Light-Emitting Diode, OLED) display has many advantages such as light and thin, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness, low power consumption and flexible screen. Excellent characteristics have aroused great interest in the scientific research community and the industry, and gradually become the third-generation display technology after liquid crystal displays (LCD). Recently, a flexible display device that can display an image under bending conditions such as paper by forming a display panel, wiring, etc. on a flexible substrate of a flexible material such as plastic has become the focus of next-generation display devices. [0003] In addition, with the development of porta...

Problems solved by technology

Among them, Metal Mesh's touch conductive electrodes often lead to very obvious moiré interference ripples due to the thick graphic lines (line widths exceeding 5 μm), and are only suitable for displays with long viewing distances.

The touch conductive electrodes of SNW often have the problem of high haze, and the haze will increase with the use of time, and the manufacturing cost is high

As the current mainstream touch electrode material, ITO has high light transmittance and good electrical conductivity, but its bending resistance is poor. Cracks appear due to long-term bending, which will cause the touch function to fail
