Abstract: A driving method for a display panel (100), and a display apparatus. The method includes: acquiring display data of a current frame and display data of a previous frame (S10); determining whether the display data of the current frame is the same as the display data of the previous frame (S20); if not, converting a default gray scale voltage corresponding to at least one sub-pixel among default gray scale voltages corresponding to a default gray scale bit number carried by the display data of the current frame into a target gray scale voltage of a target gray scale bit number, and driving the display panel (100) to display (S30).

Abstract: Embodiments of the disclosure provide a display substrate and a method for manufacturing the same. The display substrate includes: a base substrate; a thin film transistor including a source-drain metal layer and a first insulating layer; a second insulating layer; a color resist layer; and a third insulating layer. The third insulating layer comprises a first via hole that sequentially penetrates the third insulating layer, the color resist layer and the second insulating layer and thus extends from the third insulating layer to the source-drain metal layer. A sidewall of the first via hole comprises a first portion formed of a material of the second insulating layer, a second portion formed of a material of the color resist layer, and a third portion formed of a material of the third insulating layer, the second portion is between the first portion and the third portion.

Abstract: The present disclosure provides a dimming window and a method for manufacturing the same. The dimming window includes a cell defined by a first substrate and a second substrate, where at least one side edge of the first substrate exceeds an outside of the second substrate, and a part of the first substrate that exceeds the second substrate serves as a single substrate region; a first transparent conductive layer on one side of the first substrate facing the second substrate; a second transparent conductive layer on one side of the second substrate facing the first substrate; and a liquid crystal layer between the first substrate and the second substrate. The first transparent conductive layer includes a bonding region at the single substrate region; and a pattern of the bonding region includes a first sub-region and a second sub-region which are separated from each other;
the first sub-region is in a binding connection with a first driving circuit which drives the first substrate, and the second sub-region is in a binding connection with a second driving circuit which drives the second substrate; and the second sub-region is in conductive connection with the second transparent conductive layer. The dimming window and the method for manufacturing the same in the present disclosure can eliminate the need to drill holes in substrates, reduce process difficulty, reduce time consumption and improve product yield.-
