Description of the invention: • [Technical field to which the invention pertains] / The present invention relates to a liquid crystal display, and more particularly to a liquid crystal display that can operate at a low temperature. [Prior Art] Liquid crystal display is one of the best display modes because of low power consumption, miniaturization, and high-quality display. LCD display is the best display method due to low power consumption, miniaturization and high quality display (see "Atomic-beam alignment of inorganic materials for liquid-crystal displays", P. Chaudhari, et al., Nature , vol 411, p56 (2001)). At present, the more commonly used liquid crystal display is a TN (Twisted Nematic) mode liquid crystal display (TN-LCD). For TN-LCD 'When no voltage is applied to the electrode, the liquid crystal display is in the "OFF" state, and the light energy is transmitted through the liquid crystal display; when a certain voltage is applied to the electrode, the liquid crystal display is in the "ON" state. The long axis direction of the liquid crystal molecules is arranged in the direction of the electric field, and the light cannot pass through the liquid crystal display, so that the light is blocked. Selectively ® Apply a voltage to the electrodes to show different patterns. However, the low-temperature operation characteristics of the liquid crystal display screen in the prior art are inferior to those of the vehicle, which greatly hinders the use of the liquid crystal display in a low temperature environment. The main reasons for the LCD screen not working properly at low temperature are as follows: First, the value of the liquid crystal display's domain voltage is a function of the temperature. As the temperature decreases, the domain voltage rises. Therefore, the domain voltage The change will cause the contrast to deteriorate. Second, the liquid crystal display is based on the change in the state of the liquid crystal molecules to realize the display function. At room temperature, the process of changing the liquid crystal molecules is a molecular process, and its response speed is much slower than the atomic process and the electronic process. Whether it is a rising or falling process, it is a power gram: resistance: two liquid B The process of 曰 molecular state changes. As the ambient temperature drops, the dryness of the liquid crystal molecules increases, so that the resistance of the liquid crystal molecules changes, and the response speed becomes m. How to make the liquid crystal display screen work at a low temperature becomes a research hotspot. The prior art adopts one on the inner side or the outer side of the liquid crystal display substrate, and the heat f compensates the temperature of the liquid crystal display, so that the liquid crystal display shows that the material of the heating layer is usually made of indium tin oxide, and: However, since the indium tin oxide transparent conductive tantalum series resistor is more ideal, the liquid crystal display panel using the above heating layer cannot effectively improve the low temperature display effect. = 鐾 ’ ’ 4 It is necessary to provide - a kind of liquid crystal display that can be used at low temperatures.

The first transparent heating layer 207 or/and the second transparent heating layer 227 are electrically connected to the relay 50, and the digital to analog conversion module 30, the microprocessor 40 and the relay 50 are electrically connected to a power source 60, respectively. Further, the digital to analog conversion module 30 is also electrically coupled to a reference voltage 70. The microprocessor 40 is a single chip microcomputer system. The operation of heating the liquid crystal display panel 200 with the first transparent heating layer 207 or/and the second transparent heating layer 227 will be described below. The temperature sensor 10 is disposed inside the liquid crystal display 200, samples the internal temperature of the liquid crystal display 200, and the sampled analog signal is amplified and filtered by the signal processing unit 20; and then transmitted to the analog to digital conversion module. 30 performs analog-to-digital conversion, and the converted digital signal is processed by the microprocessor > 40, and outputs a pulse signal to the relay 50, and the switch contact of the relay 50 is in a pull-in state, so the power source 60 and the first transparent heating layer 207 or / and the second transparent heating layer 227 are turned on to start temperature compensation of the liquid crystal display 200. When heated to a certain temperature, when the temperature signal sampled by the temperature sensor is greater than the reference voltage 70, the microprocessor 40 controls the relay 50 to de-energize the transparent heating layer 207 or 227 to prevent the liquid crystal display panel 200 from overheating. After the power source is connected, the first transparent heating layer 207 or/and the second transparent heating layer 227 containing the carbon nanotubes can radiate electricity of a certain wavelength range. > 14 1356942 • t : specifically, The area size (length * width) of the transparent heating layer can be determined by adjusting the power supply voltage and the thickness of the transparent heating layer to emit electromagnetic waves of different wavelength ranges. When the power source is at a large timing, the thickness of the transparent heating layer is inversely proportional to the wavelength of the electromagnetic wave emitted by the transparent heating layer. That is, the size of the power supply is large. The thicker the thickness of the transparent heating layer is, the shorter the wavelength of the electromagnetic wave is radiated, the light is emitted, and the ordinary heat radiation is generated; the thinner the _ degree of the transparent heating layer is, The longer the wavelength of the electromagnetic wave is lightly emitted, an infrared heat radiation can be generated. When the thickness of the transparent heating layer is constant, the magnitude of the power supply voltage is inversely proportional to the wavelength of the electromagnetic wave radiated by the transparent heating layer. That is, when the thickness of the layer is increased, the thickness of the layer is greater than the power supply voltage, the shorter the wavelength of the transparent heating layer is, the shorter the wavelength of the electromagnetic wave is, the more visible light can be emitted and the ordinary heat is emitted; the smaller the power supply voltage is, the smaller the power supply voltage is. The longer the wavelength of the transparent heating layer that emits the electromagnetic wave, the more the infrared radiation can be generated.

The carbon nanotube film comprises a plurality of carbon nanotubes. After the carbon nanotube film connecting wire is connected to the power source, a voltage of 10 volts to 30 volts is applied, and the transparent heating layer can radiate electromagnetic waves having a long wavelength. The temperature of the transparent additive layer was found to be 5 (TC~50 (TC for a body with a black body structure..., when the temperature corresponding to 15 (S) 1356942 is 20 CTC to 450 °C). The heat that is invisible to the human eye.
