AI Technical Summary

Technical Problem

During the design process of the existing display substrate, the layout of the virtual shift register and the shift register is basically the same, resulting in the conduction between the devices connected to different signal terminals in the virtual shift register unit, causing short circuit problems and reducing the reliability of the display substrate.

Method used

By setting up a virtual driving circuit group in the non-display area of ​​the display substrate, including a virtual shift register, a virtual active pattern and a virtual control pole, and ensuring that the virtual active pattern is similar to the active pattern of the transistor, the virtual control pole is similar to the control pole of the transistor, so as to avoid the intersection of the orthogonal projection of the virtual active pattern and the virtual control pole, thereby preventing short circuit.

Benefits of technology

It effectively avoids the short circuit problem of conduction between devices connected to different signal terminals in the virtual shift register unit, and improves the reliability and display effect of the display substrate.

Abstract

The invention relates to a display platform and a display device. The display platform has a display area and a non-display area, and comprises a base, and a control circuit group and a dummy control circuit group which are arranged on the base and in the non-display area. The control circuit group comprises at least one shift register. The dummy control circuit group comprises at least one dummy shift register. The dummy shift register comprises multiple dummy operating patterns and multiple dummy control electrodes. The shift register comprises multiple transistors, wherein each transistor comprises an operating pattern and a control electrode.The shape of at least part of at least one dummy active pattern is similar to the shape of at least part of the active pattern of at least one transistor; the shape of at least part of at least one dummy control electrode is similar to the shape of at least part of the control electrode of at least one transistor; and the orthogonal projection of at least one dummy active pattern on a background without overlapping area is similar to the orthogonal projection of at least one dummy control electrode on a background.
