Problems solved by technology
However, since the temperature sensor is exposed to the outside of the liquid crystal panel, it is easily affected by the external environment, resulting in a decrease in the sensitivity of the temperature sensor; in addition, an external temperature sensing component is required, which not only increases the cost, but also occupies a volume; moreover, the temperature sensor detects The ambient temperature cannot accurately reflect the actual temperature of the thin film transistor (Thin Film Transistor, TFT) and liquid crystal in the array substrate.

The invention discloses a substrate and a display device. The substrate includes: a base substrate, a first temperature sensing part located on the base substrate, and a first processing chip connected to the first temperature sensing part. The substrate has an edge region and the middle region; wherein, a part of the first temperature sensing part is arranged in the edge region of the substrate; another part of the first temperature sensing part is arranged in the middle region of the substrate, and the first processing chip is arranged in the edge region of the substrate, with The temperature sensing signal of the middle area and the edge area of the substrate sensed by the first temperature sensing part is converted into a related control signal and output. The above-mentioned first temperature sensing part provided by the embodiment of the present invention can accurately measure the temperature difference between the edge area and the middle area of the substrate, meet the requirements of some special temperature measurement occasions, and ensure the normal display of the substrate.
Description
Technical field [0001] The present invention relates to the field of display technology, in particular to a substrate and a display device. Background technique [0002] At present, the temperature has a great influence on the characteristics of important internal components of the substrate. During the actual use of the liquid crystal panel, it is often necessary to accurately measure the temperature of the important internal components to ensure the normal display of the substrate. [0003] The main implementation of the existing temperature measurement is to detect the temperature change value of the controlled part of the liquid crystal panel through a temperature sensor on the outside of the liquid crystal panel. However, because the temperature sensor is exposed to the liquid crystal panel, it is easily affected by the external environment, which causes the sensitivity of the temperature sensor to be reduced; in addition, an external temperature sensor component is required, ...
