    摘要： The present disclosure discloses a stretch display device and a preparation method. The method includes providing a substrate on which a flexible substrate is disposed, and a film layer constituting a thin film transistor disposed on a side of the flexible substrate away from the substrate, the film layer being away from the flexible substrate. One side defines a plurality of pixel regions; a hollow portion is formed between adjacent two of the pixel regions, the hollow portion penetrates through the film layer and the flexible substrate; and thermal separation is provided in the hollow portion via a gel; a light-emitting element is disposed in the pixel region, and an encapsulating film layer is disposed on a side of the light-emitting element and the thermal separation gel away from the flexible substrate; heating the thermal separation gel, and the flexible liner. The bottom and the substrate are peeled off. Therefore, when the substrate is peeled off by this method, the problem of breakage of the flexible substrate and the film layer constituting the thin film transistor can be alleviated, and the production yield of the stretch display device can be remarkably improved.

    摘要： An array substrate and a manufacturing method thereof, and a display device are provided. The manufacturing method comprises: forming a first gate metal pattern on a base substrate; forming a gate insulating layer, a first active layer pattern and a source-drain metal pattern on the base substrate on which the first gate metal pattern is formed; forming a first protective layer pattern and a through hole pattern on the base substrate on which the source-drain metal pattern is formed; and forming a second active layer pattern and a pixel electrode pattern on the base substrate on which the first protective layer pattern is formed. Embodiments of the present disclosure solve problems of poor display performance and high cost of the array substrate and achieve effects of improving the display performance and reducing the cost.

    摘要： A light emitting device includes: a first electrode layer, a first dielectric layer, a first luminescent layer, a second luminescent layer, a second dielectric layer and a second electrode layer that are arranged sequentially in stack; a source electrode and a drain electrode, wherein the source electrode and the drain electrode are arranged in a same layer, and are both located between the first luminescent layer and the second luminescent layer; and an insulating layer provided in the same layer as the source electrode and the drain electrode, and located between the source electrode and the drain electrode. By controlling the two electrode layers separately, the two luminescent layers may separately and independently emit light. By providing different materials of the luminescent layers, the effect of light emission of multiple mixed colors or the effect of an increased light intensity may be realized.
