Abstract
The invention provides an organic light-emitting display device which comprises an array substrate and a plurality of organic light-emitting display units arranged on the array substrate, and each organic light-emitting display unit comprises an anode and a pixel definition layer arranged around the anode; the pixel definition layer comprises a first side surface far away from one side of the anode, and the first side surface comprises a first step part and a second eave part; the projection of the second eave part on the array substrate falls into the projection of the first step part on the array substrate; the organic light-emitting display device also comprises an organic light-emitting layer which is arranged on the pixel definition layer, wherein a first part of film layer, close to the pixel definition layer, in the organic light-emitting layer is disconnected between the first step part and the second eave part, and a second part of film layer, away from the pixel definition layer, in the organic light-emitting layer forms a continuous structure among the multiple organic light-emitting display units; and a cathode layer which is arranged on the upper layer of the organic light-emitting layer and forms a continuous structure among the plurality of organic light-emitting display units. The invention further provides a near-eye display device.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting display device and a near-eye display device. Background technique [0002] Existing micro-organic light-emitting display devices, such as silicon-based micro-organic light-emitting display devices, are based on monocrystalline silicon chips, and the pixel size is 1 / 10 of that of traditional display devices, and the fineness is much higher than that of traditional devices. [0003] Micro-silicon-based OLED display devices, because of their extremely small pixel size, may cause crosstalk between adjacent pixel units. Such as figure 1 As shown, it is a schematic diagram of a miniature silicon-based OLED display device in the prior art, including a substrate 10, the substrate 10 includes a plurality of pixel units, two pixel units U1 and U2 are shown in the figure, and each pixel unit includes The anode 11 disposed on the substrate 10 and the pix...
