AI Technical Summary
Existing organic light-emitting display devices are prone to color shift at wide viewing angles, resulting in significant differences in image quality, especially in display devices with long horizontal dimensions, such as automotive displays.
An anti-color shift structure is set on an organic light-emitting device, including an organic film and an inorganic film covering layer. The area and shape of the covering layer vary according to the light wavelength of the sub-pixel. By adjusting the area and shape of the covering layer, the color perception difference caused by the viewing angle is reduced.
It effectively reduces color perception changes caused by viewing angle, improves the uniformity of image recognition quality, and enhances the usability of display devices in various environments.
