Embodiment Construction

[0027] According to an embodiment of the present invention, in an organic light-emitting diode display, the light-absorbing composite layer formed by the first light-absorbing layer and the second light-absorbing layer can absorb light with wavelengths that can effectively cover the entire range of visible light, thereby effectively preventing The phenomenon of light leakage between pixel areas improves the color saturation and display effect of the display. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals are used in the drawings to designate the same or similar parts. It should be noted that the drawings have been simplified to clearly illustrate the content of the embodiments, and the detailed structures proposed in the embodiments are for illustration purposes only, and are not intended to limit the scope of protection of the present invention. Those with ordinary knowledge can ...

Abstract

The invention discloses an organic light emitting diode display. The organic light emitting diode display comprises a plurality of pixel areas, a substrate, a first electrode layer, a second electrode layer, a pixel definition layer and a light absorption composite layer. The first electrode layer is formed on the substrate. The second electrode layer is formed on the first electrode layer. The pixel areas are separated by the pixel definition layer. The light absorption composite layer is formed on the substrate, wherein the wavelength range of light absorbed by the light absorption composite layer is 380-780 nm. The light absorption composite layer comprises a first light absorption layer and a second light absorption layer, and the second light absorption layer is formed on the first light absorption layer. The first light absorption layer absorbs light relatively short in wavelength, and the second light absorption layer absorbs light which is relatively long in wavelength, is different from the light absorbed by the first light absorption layer and is 380-780 nm in wavelength.

Description

technical field [0001] The present invention relates to an organic light emitting diode display, and in particular to an organic light emitting diode display with good suppression of lateral light leakage. Background technique [0002] Organic light-emitting diode (OLED) displays have the advantages of thin thickness, active light emission without backlight, and no viewing angle limitation. As consumers expect high display quality of electronic products, the image resolution of organic light-emitting diode displays must develop toward high-resolution pixels (HighPPI; HighPixelperInch). [0003] However, in the process of manufacturing the light-emitting elements in the OLED display, due to variations in the manufacturing process conditions, etc., the panels display color unevenness, abnormality, side light leakage, or color shift. Therefore, research and development of organic light emitting diode displays with both high resolution and high display quality is one of the mos...
