Embodiment Construction

[0033] 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.

[0034] As mentioned in the background art, the display panel including the BM+CF structure has the problem of large viewing angle deviation. The inventors have found through research that the reason for the above problems is that the existing display panels usually include light-emitting units of multiple colors, and each light-emitting unit is used as a sub-pixel, and the sizes of light-emitting units of different light-emitting colors in the same direction may have different dimensions. Big difference. For exam...

Abstract

The embodiment of the invention discloses a display panel and a display device. According to the arrangement, the sub-pixels of at least one light-emitting color comprise two or more light-emitting units of the corresponding color, the sub-pixels of other light-emitting colors comprise at least one light-emitting unit of the corresponding color, and the size difference between the light-emitting unit of any color and the light-emitting units of other colors in the set direction is less than or equal to the set size, so that the size difference of different light emitting colors enabled to be small in any direction, the change difference of the area proportions of the light-emitting units with different light-emitting colors shielded by a black matrix is small along with the change in screen viewing angle of a user, so that the brightness attenuation proportions of the light-emitting units with different colors along with the change of the visual angle are consistent, the brightness attenuation proportions of the sub-pixels with different colors along with the change of the visual angle are enabled to be consistent, and the color cast of a large visual angle is improved.

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...
