Problems solved by technology
[0005] The conductivity of semiconductor materials is easily affected by temperature, so the conductivity of integrated circuits (IC) made of semiconductor materials is also affected by temperature. In theory, diodes composed of pn junctions can be used as temperature sensing components, but in practice In addition to the forward bias in the pn junction, the reverse saturation current IS will also change with temperature, so there are few people who simply use the pn junction as a sensing component, but mostly use it in the form of a transistor, and use a temperature-sensing transistor The circuit that cooperates with the amplifier circuit and is made into an IC type is called a temperature-sensitive IC. When the liquid crystal display panel is in use, it is often because the temperature inside the display panel cannot be effectively controlled, which causes the liquid crystal response speed to be delayed and image sticking.

The invention relates to a liquid crystal display panel and a display device. The liquid crystal display panel comprises a first substrate, a first polarizer, a second substrate, a second polarizer and a temperature sensor. The first substrate comprises an outer surface. The first polarizer is arranged on the outer surface of the first substrate. The second substrate is arranged oppositely to the first substrate and comprises an outer surface. The second polarizer is arranged on the outer surface of the second substrate. The temperature sensor is arranged on the peripheral of the outer surface of the first substrate or embedded in the first substrate.
Description
technical field [0001] The invention relates to a design method of an embedded temperature sensor, in particular to a liquid crystal display panel and a device. Background technique [0002] A liquid crystal display panel usually consists of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer, LC) arranged between the two substrates. Layer), its working principle is to control the rotation of liquid crystal molecules in the liquid crystal layer by applying a driving voltage on two glass substrates, and refract the light from the backlight module to produce a picture. According to the different orientation methods of liquid crystals, the liquid crystal display panels currently on the mainstream market can be divided into the following types: vertical alignment (Vertical Alignment, VA) type, twisted nematic (Twisted Nematic, TN) or super...
