Problems solved by technology

It is to make touch sensing lines on the packaging glass of the display screen, and then attach one side of the packaging glass to the OLED panel through transparent optical glue. There is no need to attach an external touch film separately, but this structure only It is suitable for making rigid AMOLED displays, and the overall thickness of the product is relatively thick, which is not suitable for the current development direction of thinner and more flexible products

Abstract

The embodiment of the invention discloses a touch screen and a corresponding OLED panel. A metal mesh touch circuit is fabricated on an encapsulation layer of a flexible OLED display screen, metal mesh touch circuit avoids the luminous zone of pixels, wire is arranged between adjacent pixels, at least one electrode of that drive electrode or the sensing electrode is connected and conducted througha metal bridge below, so that the flexible touch screen can be realized, and the thickness of the flexible touch screen becomes smaller by reducing the use of the transparent optical adhesive, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a touch screen and an OLED display panel. Background technique [0002] In recent years, the rapid development of active matrix organic light-emitting diode display (AMOLED) display technology has promoted the rapid entry of curved surface and flexible display touch products into the market, and major panel manufacturers have invested in flexible display touch projects. At present, the touch technology used with AMOLED display mainly includes the external touch film (Film) bonding solution and the rigid On-Cell technology of the glass package (referring to the touch screen embedded between the color filter substrate and the polarizer of the display screen) ), whether it is external film lamination or glass On-Cell touch technology, there is a problem that increasing the thickness of the product affects the narrow edge design. [0003] Such as figure 1 As shown, it shows a schematic structur...
