Abstract: Implementation manners of the present disclosure put forward a securities information display method, apparatus, and system. The method includes: generating a securities information display interface, where the securities information display interface displays a display bitmap of a security; determining whether the securities information display interface receives a screen sliding event, where the screen sliding event is an event generated by sliding the securities information display interface; obtaining securities data of a security corresponding to the screen sliding event when the screen sliding event is received; and updating the display bitmap based on the obtained securities data.

Abstract: Compounds are provided that are photoluminescent and electroluminescent, and may emit intense blue or deep blue light. Also provided are methods of producing photoluminescence and electroluminescence, methods of applying the compounds in thin films, and uses of the compounds described herein in a light emitting device, a luminescent probe, a sensor, and/or an electroluminescent device.

Abstract: The invention provides organoboron precursors and facile photoirradiation and/or heating methods of making corresponding elimination products. Some elimination products are polycyclic aromatic molecules wherein a number of aromatic C—C moieties have been replaced by a B—N moiety to form azaborine compounds with interesting properties such as electronic, photophysical, luminescent, as well as chemical properties. Examples of polymer films that were doped with such compounds are shown wherein irradiated portions of the polymer film luminesce. The invention further provides methods of producing photoluminescence and electroluminescence, and uses of the compounds of the invention in luminescent probes, sensors, electroluminescent devices, hydrogen storage materials, optoelectronic materials, and bioactive molecules.

Abstract: A method and an apparatus for displaying a statistical chart. The method includes determining whether a screen rotation event of switching from portrait-orientation display to landscape-orientation display is received. The method further includes obtaining additional to-be-shown data added during switch from a portrait-orientation-display drawing area to a landscape-orientation-display drawing area if yes, and drawing the landscape-orientation-display drawing area. The method further includes displaying a statistical chart in the drawn landscape-orientation-display drawing area, where the additional to-be-shown data is shown in the statistical chart. A statistical chart fills a drawing area in a landscape-orientation state.

Abstract: Organoboron ligands have been reacted with rare earth metal ions to form complexes. These ligands enhance the metal ion's luminescence, wherein enhancement of luminescence can be turned off selectively by the presence of fluoride or cyanide and luminescence at a different wavelength is turned on. Methods of detection of fluoride, cyanide and biological markers are described.

Abstract: New carbazole-based compounds are provided that are useful as host materials for singlelayer and multilayer organic light-emitting diode (OLED) devices. Highly efficient single-layer OLEDs have been demonstrated using new N-heterocyclic carbazole-based host materials. Phosphorescent OLEDs with a structure of ITO/MoO3/host/host:dopant/host/Cs2CO3/Al have been fabricated in which the new host materials act simultaneously as electron-transport, holetransport and host layer. Using this design, devices with maximum current and external quantum efficiencies of 92.2 cd and 26.8% were achieved, the highest reported to date for a single-layer OLED.

Abstract: Organoboron compounds are described that upon exposure to light absorb light and isomerize and form a dark-colored isomer. The dark-colored isomer converts back to the colorless isomer upon removal of light, or exposure to oxygen or heat. Such compounds can be added into polymeric matrices such as films. These compounds are suitable for UV-blocking, UV-detecting, and for oxygen-sensing applications. Uses include UV-blocking windows, sunglasses, and as indicators in packaging such as food packaging.
