An overlay alignment detection apparatus for a display device and an exposure process system are provided, the overlay alignment detection apparatus including a bearing frame for bearing the display device, a control circuit, a detection assembly and an analysis circuit. The control circuit is to send control commands to the detection assembly depending on pre-stored coordinate information of a reference point within an overlay area of the display device in response to the bearing frame being at an idle time among processes; the detection assembly is to be moved to the overlay area on the bearing frame according to the control commands sent by the control circuit, to acquire images of the overlay area, and to send the acquired images to the analysis circuit; and the analysis circuit is to analyze and process an overlay alignment condition of the display device, with the images sent by the detection assembly.

Overlay alignment detection apparatus for display device and exposure process system

Embodiments of this invention relate to a display substrate and a method for producing the same, as well as a display apparatus. The display substrate comprises a display area and a non-display area surrounding the display area, wherein the non-display area comprises: a first signal line, an insulating layer, and a second signal line, which are located above a base substrate, wherein projections of the first signal line and the second signal line on the base substrate are intersected with each other, and the insulating layer allows the first signal line and the second signal line to be insulated from each other; a dummy electrode in the same layer as the second signal line, and a semiconductor pad provided between the dummy electrode and the insulating layer, wherein the projection of the dummy electrode on the base substrate and the projection of the first signal line on the base substrate are intersected with each other with an intersection being located within the projection of the semiconductor pad on the base substrate.

Display substrate, method for producing the same, and display apparatus

This disclosure relates to the field of display technologies, and discloses a method for manufacturing an array substrate, an array substrate, a grayscale mask plate and a display device. The method includes forming a transparent conductive layer and a metal layer sequentially on a base substrate. A photoresist pattern is formed on the base: substrate on which the transparent conductive layer and the metal layer have been formed The transparent conductive layer and the metal layer corresponding to a photoresist-free region are removed. The photoresist in a second photoresist region is removed. The metal layer corresponding to the second photoresist region is removed to expose a pixel electrode. Additionally, the photoresist in a first photoresist region is removed to expose a first electrode, a second electrode and a first data line.
