Problems solved by technology

In order to achieve low reflection and color shift at large viewing angles (that is, integrated black at large viewing angles), the current industry mainly improves the overall black performance of OLED products by improving the parameters of polarizers, but the improvement effect is limited, making the improved OLED products. The overall black uniformity is still poor
[0004] Therefore, the technical problem of poor black uniformity existing in existing OLED products needs to be solved

Abstract

The present invention provides a display panel and a display device; the display panel includes a display panel body and a polarizer arranged in the light emitting direction of the display panel body, and the extinction property of the polarizer at the first azimuth angle is greater than that at the second azimuth angle extinction; the display panel body adopts a double-layer source-drain layer design, and the signal traces of each source-drain layer are arranged along the direction of the second azimuth angle, and the second signal traces of the second source-drain layer At least partially overlap with the orthographic projection of the first signal wiring of the first source and drain layer on the substrate to compensate for the extinction performance of the polarizer at the second azimuth angle; the present invention adjusts the shape of the metal wiring of the source and drain layer And cooperate with the polarizer to make the reflectivity and color shift of the display panel close to each other in all azimuth angles, which alleviates the technical problem of poor black uniformity of the existing OLED products.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Compared with Liquid Crystal Display (LCD), Organic Light Emitting Display (OLED) has the advantages of high color gamut, high contrast, flexibility and wearability, and has gradually become the development trend of the display industry. However, when external light is incident on the OLED display panel, the metal electrodes inside the display panel will reflect this part of the incident light, resulting in problems such as low display contrast and color shift. In order to eliminate the influence of external light on the display effect, it is usually necessary to attach a polarizer on the OLED display panel. [0003] With the development of display technology and the improvement of people's requirements for product display quality, OLED products with smaller reflectivity and color shift are highly antic...
