Abstract

The present application provides a display panel and a display device. The display panel includes a substrate, a thin film transistor layer, an organic light emitting pixel layer, a cathode, a polarizer and a reflective layer. The thin film transistor layer is arranged on the substrate; the organic light emitting pixel layer is arranged on the thin film transistor layer. Above, the organic light-emitting pixel layer includes a plurality of sub-pixels; the cathode is arranged on the organic light-emitting pixel layer; the polarizer is arranged on the cathode; the reflective layer is arranged between the cathode and the polarizer, and is used to reflect light of a specific wavelength; between the sub-pixels There is a spacer between them, the reflective layer includes a plurality of reflective units, and the reflective unit is arranged corresponding to the spacer. In the present application, a reflective layer is arranged between the organic light-emitting pixel and the polarizer to reflect the light emitted by the red sub-pixel and the green sub-pixel, thereby reducing the luminance of the red light and the green light.

Description

technical field [0001] The present application relates to a display technology, in particular to a display panel and a display device. Background technique [0002] In a full-color OLED display, the brightness balance of the three primary colors of red, green, and blue determines the balance of the white field. If the brightness of one of the three primary colors of red, green, and blue drifts, it will seriously affect the image quality and destroy the white field. Field balance distorts the color of the displayed image, so the organic light-emitting diode display will perform Gamma (gamma value) correction to reduce this white field color distortion. [0003] However, due to the inconsistency of the transmittance of the polarizer in the OLED display to the red, green and blue light, such as the brightness of the red and green chromaticity is greater than the brightness of the blue, the OLED display after the Gamma modulation is polarized. After the film, the white field ch...
