Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0041] As mentioned in the background art, the existing display panel with BM+CF structure has the problem of large viewing angle deviation. The inventors found that the reason for the above problems is that the existing display panels usually include light-emitting units of multiple colors, and the BM+CF structure usually includes a plurality of color filter units, and the color filter units are arranged in the black matrix in the opening. In the direction of the thickness of the display panel, the filter unit i...

Abstract

The embodiment of the invention discloses a display panel and a display device. At least an opening corresponding to a first color light-emitting unit is larger than the first color light-emitting unit in size by being arranged in a set direction, and the shortest distance between the first color light-emitting unit and the corresponding opening in the set direction is positively related to a first set visual angle; or in the set direction, the size of the opening corresponding to at least the first color light-emitting unit is smaller than that of the first color light-emitting unit, and theshortest distance between the first color light-emitting unit and the corresponding opening in the set direction is negatively related to the first set visual angle; the first set visual angle is an angle at which the brightness attenuation speed of the first color light-emitting unit is greater than a preset speed in the target brightness attenuation rule; the brightness attenuation of at least the first color light-emitting unit in the display panel along with the increase of the visual angle can meet the target brightness attenuation rule, and it is guaranteed that the color cast degree ofthe display panel under the large visual angle is small.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, organic light-emitting display panels are widely used due to their advantages of high brightness, wide viewing angle and low power consumption. [0003] Existing organic light-emitting display panels usually include a circular polarizer structure to eliminate the reflection of external light by the metal layer in the display panel. However, the circular polarizer structure has problems such as low transmittance and affects power consumption of the module. BM (Black Matrix, BlackMatrix)+CF (Color Filter, Color Filter) structure can be used as an alternative structure of circular polarizer. [0004] However, the display panel including the BM+CF structure has the problem of large viewing angle deviation. Contents of the invention [0005] T...
