  • Publication number: 20200091225
    Abstract: A Micro LED display panel and manufacturing method thereof are provided. The Micro LED display panel includes TFT substrate, bottom electrode positioned on top of the TFT substrate, Micro LED chip positioned on the bottom electrode, top electrode positioned on top of the Micro LED chip, and first passivation layer covering the TFT substrate and the Micro LED chip. A plurality of the bottom electrode is provided, and positioned at interval on top of the TFT substrate; the bottom of the bottom electrode is extending and conducting with a source or a drain of the TFT substrate. This disclosure directly manufacturing Micro LED chip connecting the bottom electrode and the top electrode for greatly decreases thickness of the display panel, and also achieves narrow frame. Furthermore, beside the Micro LED chip is entire passivation layer such that it does not need to multiple manufacturing method, simplify the manufacturing steps.

  • Patent number: 9859522
    Abstract: The present invention discloses a method for packaging an organic light emitting diode: allocating a position for attaching a glass cloth tape on the packaging substrate; attaching the glass cloth tape on the position; bonding an organic light emitting diode substrate to the packaging substrate; melting the glass cloth tape, so that the organic light emitting diode substrate welds together with the packaging substrate. The present invention can avoid the presence of a welding gap, so that external gas cannot enter into an internal part of the packaging body, thereby increasing the service life of the OLED device.

  • Patent number: 9634292
    Abstract: A sealant curing system and a method of curing a sealant using the same are disclosed. The sealant curing system includes a curing room and a UV light outputting panel. The curing room is used for receiving a display panel having the sealant which is ready to be cured. The UV light outputting panel is used for displaying a sealant curing image according to a preset displaying data, and is used for producing a UV light. The UV light is used for irradiating and curing the sealant of the display panel. The present invention is capable of eliminating a process in which different masks are replaced for display panels of different sizes.

  • Publication number: 20160351843
    Abstract: A quantum dot light emitting diodes display is provided. The quantum dot light emitting diodes display comprises a first electrode, a hole injection layer, a hole transmission layer, a quantum dot light emitting layer, an electron transporting layer, and a second electrode. The quantum dot light emitting layer comprises a plurality of pixel units including red sub-pixels, green sub-pixels, and blue sub-pixels. At least one color of the sub-pixels of the pixel units is formed by mixing at least two quantum dots with different peak emission wavelengths corresponding to different colors.
