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

Provided are a touch screen (1) and a corresponding OLED panel. A metal mesh touch control line is fabricated on an encapsulation layer (4) of a flexible OLED display screen, and the metal mesh touch control line is configured to avoid a light emitting area of a pixel point (7); the line runs through an area between the adjacent pixel points (7); at least one of a driving electrode or a sensing electrode is connected and conducted via a metal bridge (13) below same; and a floating electrode (113 / 123) is provided in the driving electrode or the sensing electrode, such that a flexible touch screen can be realized, wherein by reducing the use of a transparent optical glue, the thickness of the flexible touch screen is reduced, the production cost is reduced, and the touch effect is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a metal grid 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 that matches the AMOLED display mainly includes the external touch film (Film) bonding solution and the glass-encapsulated rigid On-Cell technology (referring to embedding the touch screen 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 s...
