Abstract: A light-emitting substrate includes a substrate, a plurality of sub-pixels, a first light extraction layer and a second light extraction layer. Each sub-pixel includes a light-emitting element and a light conversion pattern disposed on a light-exit side of the light-emitting element. The plurality of sub-pixels include at least one first sub-pixel. The first light extraction layer is disposed on a side of the first sub-pixel away from the light-emitting element, and at least located in a region where the at least one first sub-pixel is located. The first light extraction layer includes first transparent substrate(s) and optically active substances added in each first transparent substrate. The second light extraction layer is disposed on a side of the first light extraction layer away from the light-emitting element. A refractive index of the second light extraction layer is smaller than a refractive index of the first light extraction layer.

Abstract: Organic luminescent material, includes: host material, TADF sensitizer, and fluorescent-luminescent material; wherein absolute value of difference between LUMO level of the host material and LUMO level of the TADF sensitizer is not more than 0.4 eV, and absolute-value of difference between HOMO level of the host material and HOMO level of the TADF sensitizer is not more than 0.4 eV; absolute-value of LUMO level of the fluorescent-luminescent material is not more than absolute-value of the LUMO level of the host material and the LUMO level of the TADF sensitizer, and/or absolute-value of HOMO level of the fluorescent-luminescent material is not less than an absolute-value of the HOMO level of the host material and absolute-value of the HOMO level of the TADF sensitizer; and emission-spectrum of the host material overlaps an absorption-spectrum of the TADF sensitizer, and emission-spectrum of the TADF sensitizer overlaps absorption-spectrum of the fluorescent-luminescent material.

Abstract: A touch control assembly for the blind includes a screen protection film provided on a touch screen and configured for protecting the touch screen, and a plurality of key frames are provided at the screen protection film and are tactually sensible via fingers, wherein at least one of the key frames is provided with a braille part tactually sensible via fingers. A touch control device for the blind includes the touch control assembly for the blind. The touch control assembly for the blind, through the design of the screen protection film, the key frame, and the braille part arranged on the screen protection film, which enables the touch control assembly for the blind usable by the blind people.

Abstract: The present application provides an integrated card swiping device, which includes: a casing, a circuit board, a magnetic head, a card reader, and a card support for positioning a card. The card support defines therein a card slot for allowing the card to be inserted in, the card support is mounted inside the casing, the magnetic head is electrically connected with the circuit board, the card reader is mounted on the card support, the magnetic head is disposed on the card support, and a side of the casing defines a first opening for allowing the card to be inserted into the card slot.

Abstract: A touch screen security protection structure including a touch screen, a display screen, and a circuit board, a first signal ribbon cable, and a second signal ribbon cable. The first signal ribbon cable and the second signal ribbon cable are respectively connected with the circuit board via zebra stripes, the first signal ribbon cable and the second signal ribbon cable are provided with protection winding wires, and the protection winding wires are electrically connected with the zebra stripes via contacts. When an attacker lifts the touch screen and the display screen by cutting, the first signal ribbon cable and the second signal ribbon cable are dislocated from the zebra stripes, the protection winding wires are disconnected from the zebra stripes, anti-tampering detection signals then trigger the security response mechanism to erase the sensitive data information from the electronic components of the circuit board.
