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 present invention relates to the semiconductor technology field, especially to an AMOLED panel. The AMOLED panel is divided into a central area and an edge, and the pixel display direction of the edge area is inclined to form luminescence frequency spectrums with different optical cavity lengths which are vertical, inclined to the left and inclined to the right on the AMOLED panel, and therefore, the effects of increasing and reducing the optical cavity lengths are received at different angles to reduce the color deviation difference so as to allow the frequency spectrums received by eyes at different perspectives to relatively approach and improve the problem of the view angle color 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, ...
