Organic Light Emitting Display Device

Abstract

The invention provides an organic light emitting display device comprising a first substrate, an organic light emitting array, a film packaging protection layer, a second substrate, a sealing element and a buffer layer. The first substrate has a luminous region and a non-luminous region; the organic light emitting array is arranged at the luminous region; and the film packaging protection layer covers the organic light emitting array. The second substrate opposite to the first substrate corresponds to the luminous region and is configured with a color filter array. The sealing element is arranged between the first substrate and the second substrate and encircles the luminous region. The buffer layer arranged between the first substrate and the second substrate is arranged at the luminous region in a corresponding mode. A first light shading layer is arranged between the buffer layer and the film packaging protection layer. The sum of the buffer layer thickness and the distance between the buffer layer and the film packaging protection layer is 5 microns to 20 micros; and the hardness of the buffer layer is less than that of the color filter array.

Description

technical field [0001] The present invention relates to a display device, in particular to an organic light-emitting display device. Background technique [0002] Compared with traditional liquid crystal display devices, existing organic light-emitting display devices have advantages such as faster response speed, sharper color contrast, and almost no limitation of viewing angle, etc., and are gradually attracting attention in the display market. Secondly, the organic light emitting display device has the characteristic of self-luminescence, so it does not need to use a backlight module, which can make the display device lighter and thinner, and is less affected by different ambient lights, and can be used in both indoor and outdoor applications. [0003] The current common organic light emitting display device includes an upper substrate and a lower substrate. The lower substrate includes a thin-film transistor array and an organic light-emitting element array, and the org...

Problems solved by technology

However, when an external force is applied to the lower substrate and the upper substrate for assembly, the protruding portion of the protective layer is more likely to generate cracks due to the pressure on the upper substrate, so that water vapor easily invades the organic light-emitting element through the cracks in the protective layer, and the organic light-emitting device Light-emitting element life shortened
