However, when the OLED display is viewed at different viewing angles, the OLED display is susceptible to different variations of the OLED structure optical cavity length at different angles, and the color shift of the image display at different angles.
The OLED pixel mainly comprises R, G, B subpixels with designed optical resonant cavity length LR、LG、LBIf at the viewing angle θ, the R, G, B equivalent optical cavity length can be LR’/cosθ、LG’/cosθ、LB'/cos θ, and the color received by the eye changes accordingly. Based on our eye's limitation in the viewing angle of the light emitted by the existing AMOLED, it is highly desirable to provide a new AMOLED device with polarization efficiency to improve this concern.

The light emitting direction of pixels on an AMOLED panel designed originally is perpendicular to the AMOLED panel, and if the AMOLED panel is watched at different angles, the AMOLED panel receives light emitting spectrums at different angles, so that colors different from the vertical viewing angle are generated.
Therefore, in view of the above problems, the present invention provides an AMOLED panel, comprising:

That is, the pixel cell structures in the first region and the pixel cell structures in the second region are not parallel to the AMOLED panel, the directions in which the pixel cell structures in the first region and the pixel cell structures in the second region emit light are not perpendicular to the AMOLED panel.
In the present invention, the tilt angle α of the pixel unit structure disposed in the first region and the tilt angle β of the pixel unit structure disposed in the second region are both acute angles, and the first region and the second region are both edge regions of the AMOLED panel.
In addition to the first and second regions disposed on the AMOLED panel, a third region is disposed on the AMOLED panel, the third region is a central region of the AMOLED panel, and the tilt angle of the pixel unit structure in the third region is zero, that is, the pixel unit structure in the third region is parallel to the AMOLED panel, so that light emitted from the pixel unit structure in the third region is perpendicular to the AMOLED panel.
In the invention, on the light emitting surface side of the AMOLED panel, light emitted by the pixel unit structures arranged in the first area is deflected to the central area (namely the third area), light emitted by the pixel unit structures arranged in the second area is also deflected to the central area, and within the range acceptable by human eyes, the light emitted by the pixel unit structures in the first area and the light emitted by the pixel unit structures in the second area can be intersected or not intersected, which mainly depends on the inclination angle of the pixel unit structures in the first area, the inclination angle of the pixel unit structures in the second area and the linear distance between the human eyes and the AMOLED panel.
In the invention, a plurality of pixel unit structures are arranged in the first region, the second region and the third region, wherein each pixel unit structure comprises sub-pixels with different colors. According to the conventional selection of the AMOLED panel at present, the sub-pixels with different colors in each pixel unit structure are respectively an R sub-pixel, a G sub-pixel and a B sub-pixel, the planes of the R sub-pixel, the G sub-pixel and the B sub-pixel in the pixel unit structure in the first area are in alpha angle with the plane of the AMOLED panel, the planes of the R sub-pixel, the G sub-pixel and the B sub-pixel in the pixel unit structure in the second area are in beta angle with the plane of the AMOLED panel, and the planes of the R sub-pixel, the G sub-pixel and the B sub-pixel in the pixel unit structure in the third area are in 0 angle with the plane of the AMOLED panel.
In the invention, in the pixel unit structure arranged in a plurality of rows and a plurality of columns, on the same row of pixel unit structure, the R sub-pixel, the G sub-pixel and the B sub-pixel are arranged at intervals on the AMOLED panel, so that the adjacent R sub-pixel, the G sub-pixel and the B sub-pixel can also form a pixel unit structure, and a desired color can be gradually formed on the AMOLED panel.
