  • Publication number: 20190348001
    Abstract: A luminance compensating method of a display device, a luminance compensating device, a display device and a storage medium. The display device includes a backlight module and a display panel, the display panel includes a plurality of portions, the backlight module includes a plurality of backlight units, and the plurality of backlight units respectively correspond to the plurality of portions. The method includes: setting luminance values of the plurality of backlight units of the backlight module to an identical set luminance value, and setting gray level data of a plurality of pixel units of the display panel to an identical set gray level value; measuring light-emitting luminance values of the plurality of portions of the display panel to obtain a first luminance matrix of the display panel, in a case where the plurality of backlight units emit light; determining a compensation-coefficient matrix based on the first luminance matrix.

  • Publication number: 20170114087
    Abstract: The invention is directed to processes for synthesizing bicyclic nucleoside antiviral compounds and for synthesizing the intermediates used in the process. The invention is also directed to novel intermediate compounds useful in the process. The antiviral compounds are useful in the treatment of herpes zoster (i.e., varicella zoster virus, VZV, shingles) and for the prevention of post herpetic neuralgia (PHN) resulting from this viral infection.
