Description
Technical Field
The invention relates to the technical field of liquid crystal display, in particular to a device for improving the heating efficiency of a liquid crystal module.
Background
Liquid crystal displays are increasingly used in everyday life, but have a specific operating temperature range. The viscosity coefficient of the liquid crystal molecules in a low-temperature environment can be increased, so that a serious trailing phenomenon is caused, and the normal display of the liquid crystal screen is influenced, even the picture information can not be displayed.
Specifically, the liquid crystal display device cannot normally operate in a low-temperature environment, which affects image display. The liquid crystal screen is called as the eyes of a pilot, however, in a low-temperature environment, liquid crystal molecules are frozen and cannot be displayed normally, so that the pilot cannot obtain display picture information, and is difficult to find, lock and hit a target on the multifunctional display module timely and accurately, and the completion of battle and training tasks is seriously influenced. Most of the existing liquid crystal display heating devices are made of glass coated with an ITO (indium tin oxide) film and matched with a uniform heating compensation film. The device has the advantage of overcoming the problems of uneven surface temperature and different display effects of the liquid crystal screen caused by the fact that the edge heat dissipation is far larger than the center heat dissipation. However, this heating apparatus has problems of low thermal efficiency and high energy consumption.
Secondly, the temperature on the liquid crystal screen can be sharply increased by the backlight system and the irradiation of the external sunlight in the high-temperature environment, and the image display is influenced. The liquid crystal screen does not emit light by itself, and the liquid crystal screen is a passive light-emitting display device, and needs a backlight source to provide light, but the temperature on the liquid crystal screen can be sharply increased by heat radiation generated by the backlight source in a high-temperature environment and direct irradiation of external sunlight, so that the contrast of the liquid crystal screen is greatly reduced, the display effect is influenced, the clearing points of liquid crystal molecules are more likely to be reached, and normal display cannot be realized.
Therefore, it is important to design a liquid crystal display device capable of normally operating in a low temperature environment.

In the drawings:
fig. 1 is a schematic structural diagram of an apparatus for improving heating efficiency of a liquid crystal module according to an embodiment of the present invention.
Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, unless otherwise specified, the directional words "upper, lower" and the like included in the terms merely represent the orientation of the terms in the conventional use state or are colloquially known by those skilled in the art, and should not be construed as limiting the terms.
Referring to fig. 1, the present invention provides a device for improving heating efficiency of a liquid crystal module, including anti-reflection glass installed on the upper surface of a liquid crystal panel and heater glass installed on the back surface of the liquid crystal panel and having an ITO layer; wherein the content of the first and second substances,
the non-antireflection surface of the antireflection glass faces the liquid crystal screen and is coated with an infrared reflection film, the ITO surface of the heater glass faces the liquid crystal screen, and the non-ITO surface of the heater glass is coated with the infrared reflection film.
In this embodiment, the antireflection glass is preferably coated with an infrared reflective film and then fixed to the liquid crystal panel with an optical adhesive.
Also, in order to ensure structural stability, it is preferable that the heater glass is coated with an infrared reflection film and then fixed to the liquid crystal panel by an optical adhesive.
Therefore, the viscosity coefficient of the liquid crystal molecules can be increased in a low-temperature environment, and the heat generated by the heater heats the liquid crystal screen through two modes of heat radiation and heat conduction, so that the liquid crystal screen can normally display at a low temperature. When the heater normally works, heat energy is generated on the ITO surface, and the heat radiation energy generated downwards on the heating surface is reflected by the infrared reflection film on the other surface to improve the heating efficiency of the liquid crystal screen. And the anti-reflection glass additionally arranged in front of the liquid crystal screen is also plated with an infrared reflection film, and the infrared reflection film reflects the heat radiation energy generated by the heating surface to perform compensation heating. Meanwhile, in a high-temperature environment, the infrared reflection film plated on the heater glass can reflect heat radiation generated by backlight, so that the temperature of the liquid crystal screen during working is reduced, and the display quality of the liquid crystal screen during high-temperature working is improved.
In addition, when the liquid crystal screen works in an outdoor direct sunlight environment, the front end of the liquid crystal screen is bound with the reflection reducing glass plated with the infrared reflection film, so that heat radiation energy generated by sunlight can be reflected back, and the influence of the sunlight heat radiation on the liquid crystal screen is reduced.
Therefore, the lower surfaces of the heater glass and the antireflection glass are plated with the infrared reflection films, the utilization rate of heat radiation of the heater glass is improved, and the heating power consumption is reduced while the heating effect is ensured. Meanwhile, the display quality of the liquid crystal screen under the conditions of high temperature and strong light irradiation is improved by the special heater and the anti-reflection glass structure design.
