Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0022] The core idea of ​​the present invention is to divide the AMOLED panel into a central area and an edge area, and adjust the sub-pixel light-emitting direction of the edge area according to the problem of angle deviation caused by the different spectrums received by the eyes under different viewing angles, so that in different When viewing the AMOLED panel at an angle, the color of the approximate vertical viewing angle is received.

[0023] Originally designed AMOLED panel, the direction of pixel light emission is perpendicular to the AMOLED panel. If the panel is viewed from different angles, it will receive different angles of light emission spectrum, resulting in different colors from the vertical viewing angle.

[0024] Therefore, in view of the above problems, the present invention d...

Abstract

The invention relates to the technical field of semiconductors, in particular to an AMOLED panel. By dividing the AMOLED panel into the central area and the edge, and tilting the display direction of the pixels in the edge area, so that there are vertical, left-inclined, and right-inclined light-emitting spectra of different optical resonant cavity lengths on the AMOLED panel, resulting in The effect is that the length of the optical cavity can be increased or decreased at different angles, which can reduce the difference in color deviation, so that the spectrum received by the eyes at different angles of view is relatively close, and can improve the problem of angular deviation .

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an AMOLED panel. Background technique [0002] OLED, organic light-emitting diode, has self-illumination, simple structure, ultra-thin, fast response, wide viewing angle, low power consumption and flexible display lamp characteristics. It is known as "dream display" and is considered to be the ideal next generation Flat panel display technology. However, due to OLED luminescence spectrum viewing its display screen under different viewing angles, it is easy to be affected by the different lengths of the OLED structural optical cavity at different angles, and the luminescence spectrum received by the eyes will be different, and the color shift of the image display screen at different angles. [0003] OLED pixels are mainly composed of R, G, and B sub-pixels, and the design value of the optical resonant cavity length is L R , L G , L B , if at its viewing angle θ, its R, ...
