Embodiment 1

[0024] See figure 1 , Is a schematic cross-sectional view of an organic light-emitting display device according to Embodiment 1 of the present invention. The organic light-emitting display device includes a substrate 3, an organic light-emitting device 2 formed on the substrate 3, and an encapsulation cover 1 through which the encapsulation material It is connected with the substrate 3 to form a sealed space 4 in which the organic light emitting device 2 is encapsulated; the packaging cover 1 is located on the light emitting side of the organic light emitting device 2.

[0025] See figure 2 The package cover plate 1 is provided with several light-transmitting regions 12 and light-absorbing regions 11 located between the light-transmitting regions 12, and the light-transmitting regions 12 and the light-absorbing regions 11 do not overlap each other.

[0026] Wherein, each light-transmitting area 12 corresponds to the position of the organic light-emitting device 2, specifically, cor...

Abstract

The invention relates to an organic light emitting display device. The display device comprises a substrate, an organic light emitting device which is formed on the substrate and a packaging cover plate which is arranged on the light emergent side of the organic light emitting device. The packaging cover plate is provided with multiple light transmitting areas and light absorbing areas which are arranged among the light transmitting areas. The light transmitting areas and the light absorbing areas are not mutually overlapped, and the position of each light transmitting area on the packaging cover plate is corresponding to the position of the organic light emitting device so that the organic light emitting device is enabled to emit light through the light transmitting areas, and the light absorbing areas absorb light of which the wavelength range is within 380nm-780nm. According to the organic light emitting display device, the brightness performance and the contrast performance of the display device can be greatly balanced on the whole so that the overall display effect can be improved.

Description

Technical field [0001] The invention relates to the field of organic electroluminescence, in particular to an organic light emitting display device. Background technique [0002] Organic light-emitting devices are devices that use carriers injected after applying voltage to recombine and excite organic materials to emit light. They have self-luminescence, high efficiency, low voltage, fast response, wide viewing angle, and can be used on flexible substrates. They can be made into displays. Or lighting devices have attracted much attention from society. [0003] Organic light-emitting diodes (OLEDs) are self-luminous display devices and are widely used in the display field. For OLED, contrast is a very important display performance parameter. It can generally be simply defined as the ratio of useful light (such as signal) to useless light (such as noise) emitted by the display. In the actual application environment, the useless light depends on Light reflected from the outside wor...
