Abstract: The present invention relates to a novel indene derivative, a preparation method for the same, and a pharmaceutical composition for treating retinal disease comprising the same as an active ingredient. The novel indene derivative of the present invention, the optional isomer of the same, or the pharmaceutically acceptable salts of the same have excellent inhibitory efficiency of receptor-interacting serine-threonine-protein kinase 1 (RIPK1). Therefore, the composition containing the same as an active ingredient can be effectively used as a pharmaceutical composition for treating retinal disease.

Abstract: The present invention relates to a composition containing a paprika extract as an active ingredient, and more particularly to a pharmaceutical composition or health functional food for preventing or treating inflammatory, allergic or asthma disease, which contains a paprika extract. Particularly, paprika is a natural food which is readily available to anyone, and thus does not cause adverse effects even when it is taken for a long period of time.

Abstract: A display device includes a display panel, a variable gate clock generator and a gate driver. The display panel includes a plurality of pixels coupled to a plurality of data lines and a plurality of gate lines, respectively. The variable gate clock generator generates a first variable gate clock signal and a second variable gate clock signal having respective duty ratios that are varied depending on a brightness of a frame image. The gate driver generates a plurality of gate driving signals for driving the gate lines in response to the first and second variable gate clock signals.

Abstract: A slim electronic device is provided. The slim electronic device includes a substrate having an opening formed therein, and an audio component accommodated in the opening of the substrate without overlapping the substrate and disposed such that the top and bottom thereof are substantially parallel to the top and bottom of the substrate.
