AI Technical Summary
Technical Problem
Liquid crystal displays (LCDs) have a slow response time in low-temperature environments, which affects normal display.
Method used
Heating traces that intersect with the first display signal lines are set on the array substrate. The liquid crystal layer is heated by the heating traces to improve the response speed of the liquid crystal molecules. By setting the overlap area design between the heating traces and the display signal lines, parasitic capacitance and coupling power consumption are reduced.
Benefits of technology
Improve the display effect and performance of liquid crystal display devices in low-temperature environments, while reducing power consumption.

Abstract
The application discloses a display panel, a preparation method thereof and a display device. The array substrate of the display panel comprises a plurality of heating wires and a plurality of first display signal lines which are arranged in different layers and cross each other. The heating wire comprises a first section and a second section arranged along a first direction. The vertical projection of the second section on a substrate is overlapped with the vertical projection of the first display signal line on the substrate. The area of the second section per unit length is smaller than the area of the first section per unit length along the first direction. The display panel, the preparation method thereof and the display device provided by the application reduce the area of the overlapped part of the heating wire and the first display signal line, reduce the parasitic capacitance formed between the heating wire and the first display signal line and the coupling power consumption, and improve the display effect and display performance of the display panel at low temperature under lower power consumption.
