TECHNICAL FIELD

[0001] The utility model relates to liquid crystal display screen technical field, concretely to a new type low temperature under liquid crystal screen heating device. BACKGROUND

[0002] When liquid crystal display screen works in low temperature environment, the fluidity of liquid crystal molecules will decrease significantly, resulting in a series of display problems, response time extension: the activity of liquid crystal molecules reduces, resulting in screen response speed slows down; refresh rate reduction: the refresh frequency of liquid crystal display screen drops, influences the fluency of dynamic picture; dynamic picture ghosting: due to the poor fluidity of liquid crystal molecules, dynamic picture is prone to ghosting phenomenon; static image color distortion and contrast reduction: under low temperature environment, the color performance and contrast of liquid crystal display screen are all influenced, resulting in poor display effect.

[0003] In view of the display problem of liquid crystal display screen under low temperature environment, the general solution mainly has the following two kinds, ultralow temperature liquid crystal material: develop the liquid crystal material that can still keep good fluidity under extremely low temperature, improve the activity and electron transmission speed of liquid crystal molecules; temperature control technology: through adding temperature control module behind liquid crystal display screen, the temperature of liquid crystal panel is monitored and adjusted in real time, ensure that it can still work normally under harsh environment, therefore, in view of the above problem, a new type low temperature under liquid crystal screen heating device is provided. UTILITY MODEL CONTENT

[0004] To solve the problems in the background art, the utility model aims at providing a new type low temperature under liquid crystal screen heating device, which has the advantages of maintaining good fluidity under extremely low temperature and monitoring and adjusting the temperature of liquid crystal panel in real time, and solves the problem of display of liquid crystal display screen under low temperature environment without increasing additional materials and cost.

[0005] To achieve the above object, the utility model provides the following technical scheme: a new type low temperature under liquid crystal screen heating device, comprising lower layer LCD glass:

[0006] Heating mechanism, the heating mechanism is arranged at the bottom of LCD glass, the heating mechanism includes lower layer ITO heating electrode, the top of lower layer ITO heating electrode is provided with upper layer ITO heating electrode, and the top of upper layer ITO heating electrode is provided with upper layer LCD glass.

[0007] As preferred in the utility model, the right side of the lower layer ITO heating electrode and the left side of the upper layer ITO heating electrode are both provided with FPC electrode.

[0008] As preferred in the utility model, the left side and the right side of the lower layer LCD glass and the upper layer LCD glass are both provided with heat insulation module.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This invention utilizes a combination of a lower LCD glass layer, an upper LCD glass layer, a lower ITO heating electrode, and an upper ITO heating electrode. Heating resistor patterns are etched onto the outer surfaces of the lower and upper ITO heating electrodes on both layers. When the temperature control circuit is powered on, the heating resistors activate, generating heat that is transferred to the liquid crystal molecules through the LCD glass, thereby increasing the LCD's operating temperature. A temperature sensor monitors the LCD's operating temperature in real time and feeds the temperature signal back to the temperature control circuit. The temperature control circuit automatically adjusts the power of the heating resistors according to the set temperature range, ensuring that the LCD maintains a temperature of 10 degrees Celsius even in low-temperature environments, and ensuring normal operation even in harsh environments.

[0011] 2. This utility model, through the setting of FPC electrodes, can assist the lower ITO heating electrode and the upper ITO heating electrode. In the LCD screen heating device, it connects the lower ITO (indium tin oxide) heating electrode and the upper ITO heating electrode, playing a key role in transmitting current. Because the ITO heating electrode requires an external power supply to generate heat, the FPC electrode can ensure a stable current is transmitted from the external power supply to the ITO heating electrode, ensuring the normal realization of the heating function.
