An array substrate includes a planarization layer; an anode material layer on the planarization layer and in a peripheral area of the array substrate; and a plurality of gas releasing vias extending through the anode material layer configured to release gas in the planarization layer during a fabrication process. An aperture size of a first respective gas releasing via in a first region is smaller than an aperture size of a second respective gas releasing via in a second region.

Array substrate and display apparatus

A display substrate includes a plurality of data lines and a plurality of columns of pixel driving circuits. A column of pixel driving circuits is connected to a corresponding data line, and each pixel driving circuit includes a driving transistor and a first transistor. The driving transistor is a P-type transistor. The first transistor includes: a first active pattern having a first channel region, and a first doped region and a second doped region on two opposite sides of the first channel region; a first gate; and a first insulating block disposed on a side of the first active pattern away from the base and having a first via. The data line is connected to a portion of the first active pattern located in the first doped region through the first via. Sizes of all first vias in the column of pixel driving circuits gradually decrease in a first direction.

Display substrate, display panel and display apparatus

Preparation method of aromatic boronate compound is provided, in which the is as follows: reacting aromatic amine Ar-NH, with diboronic ester and alkyl nitrite in the presence of organic solvent, where Ar represents non-heterocyclic aryl. It enables for the first time the preparation of aromatic boronate from aromatic amine in one step by the present method.
