    摘要： A driving backplane includes a base, and a pixel driving circuit, a first electrode and a first piezoelectric block that are disposed in the sub-pixel region. The pixel driving circuit is disposed on the base. The first electrode is disposed at a side of the pixel driving circuit away from the base. The first electrode includes a first sub-electrode pattern and a second sub-electrode pattern that are in a same layer and are spaced apart to be insulated from each other, and the first sub-electrode pattern is electrically connected to the pixel driving circuit. The first piezoelectric block is disposed between the pixel driving circuit and the first electrode, and the first sub-electrode pattern and the second sub-electrode pattern are in contact with the first piezoelectric block.

    摘要： A display substrate, a manufacturing method thereof, and a display device are provided, in the field of display technology. The display substrate includes a base substrate, and a thin-film transistor, a light-emitting device, an encapsulation structure, and a conductive film layer sequentially disposed on the base substrate in a direction away from the base substrate. Since the display substrate includes a conductive film layer on a side of the encapsulation structure away from the base substrate, when the protective film layer on the side of the conductive film layer away from the base substrate is peeled off, static electricity generated by the separation of the film layer can be released to the conductive film layer, avoiding electron transition to the active layer of the thin-film transistor in the display substrate to cause offset of the threshold voltage of the thin-film transistor. The display brightness uniformity of the display substrate can be ensured.

    摘要： A display panel is provided with a plurality of sub-pixel areas and includes: a base substrate, a light emitting structure including a plurality of light emitting devices corresponding to the sub-pixel areas, an encapsulating layer, and a pixel defining layer. The pixel defining layer includes: a plurality of openings; at least two sub-pixel defining layers, and a quantum dot color film layer. Each of the sub-pixel defining layers is provided with a pixel separator. The pixel separators fence each of the plurality of openings, and define the plurality of sub-pixel areas. In the at least two sub-pixel defining layers, the sectional shape of the pixel separator in the sub-pixel defining layer which is farthest away from the encapsulating layer includes a regular trapezoid. The quantum dot color film layer includes a plurality of quantum dot color films arranged in the corresponding openings.
