With the growing demand for high‐quality Organic Light Emitting Diode (OLED) display, the design of screen structure by panel manufacturers needs to consider optical performance optimization carefully, such as Wide Angle Difference (WAD). The users hope that visual color bias of the OLED display on different angles appears as small as possible, and no red visual test will be particularly accepted. The OLED display panel is usually composed of Array substrates, OLED devices, Thin Film Encapsulation (TFE) layers, touch units, Polarizers and top cover plates. The touch units contain a metal mesh, which is distributed throughout the display screen and has a great impact on the optical performance of large viewing angles. This paper aims to clarify the optical design requirements of metal mesh and provide reference for OLED optical display designers.
