Abstract: The present disclosure provides a positive photoresist composition including a major adhesive material and a photosensitizer, wherein the photoresist composition further includes a photoisomerizable compound which would be converted into an ionic structure with an increased degree of molecular polarity after ultraviolet irradiation. The formation of the ionic structure with increased polarity of the molecule reduces the adhesion between the positive photoresist and the organic film layer, facilitates stripping after formation of the via, and improves the product rate of pass. Further, the present disclosure provides a via-forming method using the positive resist composition, a display substrate including the via formed by the via-forming method, and a display device including the display substrate.

Abstract: An array substrate, display device and image display method. In this array substrate, among the sub-pixels two adjacent columns of sub-pixels are grouped together, and sub-pixels in different groups do not overlap each other; in each group, all of the sub-pixels are electrically connected with a same data line; each row of the sub-pixels corresponds to two gate lines, and in each row of the sub-pixels, two sub-pixels belonging to the same group are electrically connected with one of the two gate lines corresponding to this row of the sub-pixels respectively; thus, in the process of sequentially loading a gate scanning signal to each grid line within the display time of one frame, charging difference between rows of sub-pixels caused by the jump of voltage loaded on the data line may be reduced, whereby poor stripes present when a flat panel display is displaying a screen may be improved.
