  • Publication number: 20150006983
    Abstract: A read voltage setting method for a rewritable non-volatile memory module is provided. The method includes: reading test data stored in memory cells of a word line to obtain a corresponding critical voltage distribution and identifying a default read voltage corresponding to the word line based on the corresponding critical voltage distribution; applying a plurality of test read voltages obtained according to the default read voltage to the word line to read a plurality of test page data; and determining an optimized read voltage corresponding to the word line according to the minimum error bit number among a plurality of error bit numbers of the test page data. The method further includes calculating a difference value between the default read voltage and the optimized read voltage as a read voltage adjustment value corresponding to the word line and recording the read voltage adjustment value in a retry table.

  • Publication number: 20140138627
    Abstract: Novel devices containing organic compounds containing electron donor and acceptor characteristics and that act as emissive dopants are provided. The energy ratio obtained by dividing the T1 energy of the emissive dopant by ?EHOMO-LUMO for the same emissive dopant is at least 0.7 and the first emissive dopant has an energy difference calculated by subtracting the T1 energy of the first emissive dopant from ?EHOMO-LUMO for the first emissive dopant and the energy difference is at smaller than or equal to 1.00 eV for the novel compounds. The compounds exhibit delayed fluorescence properties when incorporated into OLED devices.

  • Publication number: 20130241401
    Abstract: Novel diarylamino phenyl carbazole compounds are provided. By appropriately selecting the nature of the diarylamino substituent and the substitution on the carbazole nitrogen, compounds with appropriate HOMO and LUMO energies can be obtained for use as materials in a secondary hole transport layer.
