    Abstract: An image display device with organic light-emitting diodes (OLEDs) includes a first cover and an organic light-emitting diode (OLED) module. The first cover has a first light transparent zone and a first mask zone. The first light transparent zone forms a first image. The first mask zone is complementary with the first light transparent zone. The OLED module is positioned against the first cover and includes a plurality of juxtaposed organic light emitting diode (OLED) pixels emitting light to project to the first cover. The light includes transmission light and reflective light. The transmission light passes through the first light transparent zone to display the first image. The reflective light is blocked by the first mask zone. Thus the first image can be displayed with a continuous and smooth border on the curvature contour to improve resolution and visual appeal.
