Problems solved by technology

However, limited by the liquid crystal material, the response time of the liquid crystal is prolonged at low temperature. After the response time of the liquid crystal is prolonged, the display quality will deteriorate, and problems such as tailing and shadowing will appear in the dynamic image, which will affect the visual effect.
When the temperature drops further (below -30°C), the alignment layer of the display will be destroyed, the liquid crystal state will disappear, become a crystal, lose the performance of the liquid crystal state, and the screen will not be displayed

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display, the display panel comprises a control chip located in a non-display area on the first side of the display panel, the control chip is at least electrically connected with a data line, and the first side is adjacent to the display area in the second direction; the heating driving assembly is located in the non-display area of the first side and electrically connected with the heating wire through the heating bus; the gate driving assembly is located in the non-display area of the second side of the display panel, and the second side is adjacent to the first side; the gate driving assembly is electrically connected with the gate line and is electrically connected with the control chip through a first lead; in the third direction, the heating bus and the first lead are not overlapped, or the first lead and the heating bus are at least partially overlapped to form an overlapping area, and one of the overlapping area, the first lead and the heating bus is provided with a hollow part; or the thickness of the insulating layer between the first lead and the heating bus in the overlapping region is greater than that in the non-overlapping region. Therefore, the reliability of low-temperature display is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Liquid crystal is a special form of material, which not only has birefringence peculiar to crystal, but also has the fluidity of liquid. A liquid crystal display is a display device made by using liquid crystal molecules to change their optical properties under the action of an external electric field. It has various types and has been widely used in various displays and electronic instruments. However, due to the limitation of liquid crystal materials, the response time of liquid crystal is prolonged at low temperature. After the response time of liquid crystal is prolonged, the display quality is deteriorated, and the dynamic image has problems such as tailing and smearing, which affects the visual effect. When the temperature drops further (below -30°C), the alignment layer of the display wi...
