Abstract:
The present application discloses an array substrate comprising a light emitting region comprising a plurality of light emitting units. Each of the plurality of light emitting units comprises a first emissive layer of a first light emitting material for emitting a compound light having a first color and a second color; the first color corresponding to a color of light emitted from a first sub-pixel and the second color corresponding to a color of light emitted from a second sub-pixel; and a second emissive layer of a second light emitting material corresponding to a third sub-pixel for emitting light of a third color. The first color and the second color are different from a color of light from the first emissive layer.
Abstract:
A display panel includes a first substrate, a second substrate, an OLED device, a first connection structure and a second connection structure. The second substrate is arranged opposite to the first substrate and includes a display area and a peripheral area. The OLED device is arranged between the second substrate and the first substrate. The first connection structure is arranged between the second substrate and the first substrate and is connected with the second substrate and the first substrate, and the first connection structure is located at the peripheral area to surround the OLED device. The second connection structure is arranged between the second substrate and the first substrate and is connected with the second substrate and the first substrate, and the second connection structure is located at the peripheral area and is far away from the display area than the first connection structure.
Abstract:
The disclosure relates to an OLED element, an OLED device, and an OLED display device. An OLED element includes: at least two light emitting elements stacked, wherein at least one light emitting element includes light emitting layers in at least two colors, and coverage areas of positive projections of the light emitting layers in the different light emitting elements onto either surface of the OLED element at most partially overlap with each other. The colors from the light emitting layers in the different colors arranged in the same light emitting element can be mixed with the colors from the light emitting layers in the other light emitting elements, and the mixed colors can be further adjusted to the desirable color.
Abstract:
An organic light-emitting diode (OLED) display panel and a display device are provided. A pixel unit of the OLED display panel includes a first sub-pixel, a second sub-pixel and a third sub-pixel and further includes an anode layer, a cathode layer and an organic function layer. The organic function layer includes: a first emission layer (EML1) configured to cover at least two adjacent sub-pixels comprising the first sub-pixel; a carrier blocking layer (CBL) configured to cover the second sub-pixel and the third sub-pixel; a second emission layer (EML2) arranged at an area provided with the first sub-pixel and the second sub-pixel and configured to at least cover the second sub-pixel; and a third emission layer (EML3) configured to cover at least two adjacent sub-pixels comprising the third sub-pixel. The OLED display panel can improve the pixel density.
