Problems solved by technology

However, the blackening process of the metal grid 131' will affect the electrical properties of the metal grid 131', thereby reducing the touch accuracy of the touch display panel.
[0005] It can be seen that the structure of the touch display panel in the prior art cannot guarantee the low reflectivity and touch accuracy of the touch panel at the same time.

Abstract

The invention provides an OLED display panel and a touch panel. The touch panel comprises a linear polarizer, a 1 / 2 wave plate layer, a 1 / 4 wave plate layer and a touch electrode layer, wherein the 1 / 2 wave plate layer is formed on one side of the linear polarizer, the 1 / 4 wave plate layer is formed on one side, away from the linear polarizer, of the 1 / 2 wave plate layer, the touch electrode layer is formed on one side, away from the linear polarizer, of the 1 / 4 wave plate layer and comprises a plurality of touch electrodes, and the touch electrodes are meshed metal grids. The OLED display panel and the touch panel have the advantages that panel reflectivity is reduced, and panel touch precision is increased at the same time.

Description

technical field [0001] The invention relates to the field of display and touch control, in particular to an OLED display panel and a touch panel. Background technique [0002] With the development of human-computer interaction technology, touch technology is increasingly used on various displays. Capacitive touch technology is widely used due to its advantages of wear resistance, long life, low maintenance cost for users, and support for gesture recognition and multi-touch. [0003] Part of the structure of the existing touch display panel is usually as follows figure 1 shown. A circular polarizer 120 is arranged on the cathode 110, and the external light passes through the circular polarizer 120 to form circularly polarized light, and the reflection of the circularly polarized light on the cathode 110 forms circularly polarized light of opposite chirality, and the circularly polarized light of opposite chirality passes through The circular polarizer 120 is filtered to re...
