Curved display panel and display device

Abstract

The invention discloses a curved display panel and a display device. In the direction where the center of the zero viewing angle of the curved display panel extends toward the first side and the second side, and the observation angle gradually increases, by gradually increasing the volume concentration of the guest material in the organic light-emitting layer, or gradually reducing the volume concentration of the organic light-emitting layer The energy gap of the guest material, or by setting a functional layer with a gradually increasing thickness between the first electrode and the second electrode, the wavelength of the peak of the light emitting spectrum of the organic light emitting diode is also gradually increased, thereby suppressing the fluctuation of the peak position of the light emitting spectrum The blue shift phenomenon, therefore, can improve the color difference of different display areas of the curved display panel under the viewing angle of the viewer, and improve the display effect of the curved display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (Organic Light-Emitting Diode, hereinafter referred to as OLED) display panel is thin, light, wide viewing angle, active luminescence, continuously adjustable luminous color, low cost, fast response, low energy consumption, drive The advantages of low voltage, wide operating temperature range, simple production process, high luminous efficiency and flexible display have been listed as a promising next-generation display technology. [0003] Such as figure 1 As shown, an existing OLED display panel includes a plurality of color light-emitting units arranged in an array, and each color light-emitting unit includes R (red) pixels, G (green) pixels, and B (blue) pixels arranged side by side. , Adjacent pixels are bounded by a pixel definition layer 04, wherein each pixel include...

AI Technical Summary

Problems solved by technology

[0004] like figure 2 As shown, the defect of the prior art is that, for the curved display panel 001, when the viewing angle of the viewer changes from the zero viewing angle center 09 of the curved display panel 001 to the edge position where the observation angle gradually increases, that is, the observation angle changes from 0° Gradually increases to α 1 、α 2 、α 3 , the wavelength of the peak of the luminous spectrum of the light-emitting device will gradually decrease, that is, the position of the peak of the luminous spectrum will appear blue-shifted, and the viewer will therefore feel that the center of the display panel is inconsistent with the color of the edge.
