Abstract: A back-film structure may include a first back-film portion which serves as a first circle upon rolling and a second back-film portion arranged side by side with the first back-film portion in the rolling direction, wherein a thickness of the first back-film portion increases in the rolling direction. This solution can ensure that the inner surface of the tail end of the first back-film portion is located as close as possible to the inner surface of the head end of the first back-film portion after the rolling.

Abstract: An organic light-emitting device and a manufacturing method therefor. The organic light-emitting device is provided, at a light-exiting side thereof, with a transparent light-exiting member at least comprising a light-exiting layer (11), at least one surface of the light-exiting layer (11) having a first waved shape. Due to the waved interface, the organic light-emitting device can prevent light from being reflected back and forth in a parallel manner in the interface, and further prevent light from propagating in the interface of the device in the form of a waveguide, reducing the optical loss due to the light being reflected back and forth in the interface, and further increasing the light extraction efficiency of the organic light-emitting device.

Abstract: The present disclosure provides a display substrate, a detection method and a detection apparatus. The display substrate includes a display region and a peripheral region surrounding the display region. The display substrate further includes a display element arranged at the display region, a thin film encapsulation layer covering the display element, and at least one detection structure arranged at the peripheral region. At least one detection structure which is not covered is configured to receive a light beam and generate a first reflected light beam. At least one detection structure which is covered by the thin film encapsulation layer is configured to receive the light beam and generate a second reflected light beam. A first optical parameter of the first reflected light beam is different from a second optical parameter of the second reflected light beam.

Abstract: Disclosed is an array substrate, a display panel, and a display device. The array substrate includes: a substrate (100), a plurality of pixel units (110) disposed on a side of the base substrate (100), a chip (200) configured for providing signal to the pixel units (110), signal lines (120) corresponding to each of pixel units (110), and via holes (130) penetrating the base substrate (100). By disposing the chip (200) on the side of the base substrate (100) opposed to the pixel units (110) and electrically connecting the pixel units (110) to the chip (200) through the signal lines (120) in the via holes (130), the frame portion which is used for accommodating the chip could be omitted and a real frameless design is achieved.
