Description
Technical field
The present invention relates to ruggedized monitor technical field, a kind of reinforced liquid crystal displays low-temperature heating method of concrete offer.
Background technology
Development along with society, reinforced liquid crystal displays is the most more and more applied in weapon system-of-systems in recent years, the deep development built along with military informationization, in battlefield, the operational commanding of the armies of navy, army and air force, weapon control and information processing system, either Large fixed facilities, movable machinery or portable instrument, it is necessary to configuration ruggedized monitor is to provide various information for user.Ruggedized monitor is as a kind of important Support Equipment, and along with the development of military equipment modernization, use will be gradually increased, the performance to sophisticated weapon system fighting capacity of the quality of its performance and function, plays critical effect.Reinforced liquid-crystal display is based on general commercial liquid crystal display, its humiture, machinery, optics, Electronic Performance are further improved and improve, make it meet the requirement of military scenario, there is stronger environmental suitability, normally can work under various adverse circumstances.And liquid crystal molecule viscosity coefficient at low ambient temperatures can be greatly increased, causing its response time elongated, image or light rotating savings produce serious hangover, it is impossible to normally show.Current reinforced liquid crystal displays is to meet normal work at low temperatures, mostly uses and heats liquid crystal display screen at low temperatures, makes liquid crystal display screen reach normal operating temperature.
In the patent documentation of Patent No. CN201331909Y, disclose a kind of heating control system of liquid crystal display.The heating control system of this structure is made up of temperature control system, heating system, electric power system and display system, and temperature control system is connected with heating system, electric power system and display system respectively.Temperature control system is connected in sequence by relay, single-chip microcomputer and temperature sensor；Heating control system is high-power heating film；Electric power system is connected in sequence by power input interface, protective tube, wave filter and power module；Display system is formed by connecting with OSD plate, backlight and liquid crystal display screen respectively by VGA plate.Wherein heating system and display system share a 12V power supply.Improve power utilization rate by the heating control system of this structure, save the space of casing, LCDs can be made again to reach normal operating temperature.But the heating control system of this structure power consumption when heating for LCDs is relatively big, and the heating to liquid crystal display screen can produce uneven problem, is therefore badly in need of the LCDs heating means of a kind of low-power consumption and homogeneous heating.
Summary of the invention
The technical assignment of the present invention is the problem for above-mentioned existence, it is provided that a kind of low in energy consumption, and has heating compensation function, such that it is able to the reinforced liquid crystal displays low-temperature heating method of heating uniform to LCDs.
For achieving the above object, the technical scheme is that
A kind of reinforced liquid crystal displays low-temperature heating method, comprises the following steps:
S1: arranging heating compensation unit between heating film and LCDs edge, described heating compensation unit is connected with temperature sensor, singlechip controller respectively, compensates the temperature difference of LCDs edge and centre position；
S2: install incubation chamber at the window that LCDs heat radiation is the most serious, cut off the path that LCDs internal heat is outwards scattered and disappeared.
Described heating film is attached on liquid crystal display panel, is used for heating for LCDs.The model of described temperature sensor is DS1821(PR35), it is connected with heating film, gathers the temperature of LCDs.Described singlechip controller is AVR single chip, is connected with temperature sensor, receives the temperature information of the LCDs of temperature sensor feedback.Singlechip controller is also connected with heating film, controls the heating of heating film.By the temperature control program of singlechip controller, it is possible to realize whole reinforced liquid crystal displays and carry out automatic computer heating control at low ambient temperatures.
The detailed process of the method is: will carry out power on operation under reinforced liquid crystal displays low temperature, and is powered on by singlechip controller and initialize.Call the relative program of temperature sensor and gather the temperature in LCDs centre position and the temperature of LCDs edge, and the hexadecimal temperature data collected is converted into decimal scale temperature data is stored in the memory element specified.The temperature data collected is fed back to singlechip controller by temperature sensor, is compared with the temperature value of default by the temperature data in LCDs centre position collected, it is judged that whether both have temperature difference.If there being temperature difference, LCDs is heated by the temperature heating schedule then controlling heating film, temperature sensor simultaneously gathers the real time temperature of LCDs, and the temperature information collected is fed back to singlechip controller, stops heating when LCDs temperature reaches setting value；If the temperature in LCDs centre position does not has temperature difference with the temperature value of default, then the temperature of the temperature in LCDs centre position with position, LCDs edge is compared, determine whether temperature difference, if there being temperature difference, then controlled to call the temperature-compensating program of temperature compensation unit by singlechip controller, the edge of LCDs is heated, temperature sensor simultaneously gathers centre position and the temperature of edge of LCDs, and the temperature information collected is fed back to singlechip controller, when LCDs centre position does not has temperature difference with edge, temperature compensation unit quits work, heating and temperature-compensating complete.Effectively stoped by incubation chamber and reinforce scattering and disappearing of the heat that produces in the course of the work of LCDs, greatly reduce the heating power consumption of heating film.
As preferably, described heating compensation unit is by heat conduction thin film and adds thermode and matches and form, and for heating for LCDs edge, compensates the temperature difference of LCDs edge and centre position.
Described incubation chamber is that transparent vacuum seals structure, and removably connects with liquid crystal display, when liquid crystal display uses in the environment that temperature is higher, incubation chamber can be disassembled, improve its range.As preferably, the incubation chamber of the present invention is adopted and is connected with display in the method for paste.
Compared with prior art, the present invention has a beneficial effect highlighted below:
(1) the method for the invention arranges heating compensation unit between heating film and LCDs edge, when the centre position of LCDs and edge exist temperature difference, edge can be heated, it is ensured that the uniformity of LCDs temperature；
(2) present invention installs the incubation chamber that transparent vacuum seals at the window of LCDs, scattering and disappearing of the heat produced when display can be stoped to work, by thermal accumlation, store, decrease heating film and display screen is heated to the time of assigned temperature, greatly reduce heating power consumption, and incubation chamber is detachably arranged at display screen windows, expand range.
