Abstract
The invention discloses a liquid crystal display screen with a heating function. The liquid crystal display screen comprises a temperature sensor, a detection module, a control module and a judgment module, wherein the detection module is used for detecting whether the liquid crystal display screen is in a running state or not; the control module is connected with the detection module and the judgment module, and is used for controlling the judgment module to judge whether the current temperature, detected by the temperature sensor, of the liquid crystal display screen is lower than a preset temperature threshold value or not, controlling the heating module to start heating according to a judgment result indicating that the current temperature of the liquid crystal display screen is lower than or equal to the preset temperature threshold value, and controlling the heating module to stop heating according to the judgment result indicating that the current temperature of the liquid crystal display screen is higher than the preset temperature threshold value after the heating of the heating module. According to the liquid crystal display screen, the heating module can be used for heating when the temperature of the liquid crystal display screen is too low, so that the performance of the liquid crystal display screen is ensured, the service life is prolonged, and the application range of the liquid crystal display screen is widened.
Description
Technical field
The present invention relates to a kind of LCDs with heating function.
Background technology
Traditional display mode is as CRT crt display and LED display board etc., all be limited by the factors such as the excessive or power consumption of volume is very huge, the actual demand of user cannot be reached, and the development of lcd technology just in time suits the trend of current information products, no matter be right angle display, low power consumption, volume is little, or the advantages such as zero radiation, user can be allowed to enjoy best visual environment, but because liquid crystal is a kind of particular matter between solid and liquid, it is a kind of organic compound, be in a liquid state under normality, therefore the situation of hydraulic performance decline all can be there is at low ambient temperatures in a lot of LCDs, have impact on the range of application of LCDs.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of LCDs with heating function.
Technological means of the present invention is as follows:
There is a LCDs for heating function, comprising:
For detecting the temperature sensor of LCDs Current Temperatures;
The detection module of running status whether is in for detecting LCDs;
Connection detection module and judge module, when LCDs for exporting according to detection module is in the result of running status, control judge module whether to judge lower than equaling preset temperature threshold value the LCDs Current Temperatures that temperature sensor detects, and start heating according to LCDs Current Temperatures lower than the judged result control heating module equaling preset temperature threshold value, and after heating module performs heating action, according to the control module of LCDs Current Temperatures higher than the judged result control heating module stopping heating of preset temperature threshold value;
Connect temperature sensor and control module, for judging that according to the control information of control module whether LCDs Current Temperatures that temperature sensor detects is lower than the judge module equaling preset temperature threshold value;
Further, whether described detection module is in opening judges whether LCDs is in running status by detecting the backlight that has of LCDs;
Further, described heating module is be arranged on the electric heating film on liquid crystal layer that LCDs has.
Owing to have employed technique scheme, a kind of LCDs with heating function provided by the invention, temperature sensor is adopted to detect LCDs Current Temperatures parameter, control module controls judge module and carries out work when LCDs is in running status, judge module compares LCDs Current Temperatures and preset temperature threshold value, heating is started when LCDs Current Temperatures controls heating module lower than control module when equaling preset temperature threshold value, the heating module heating when LCDs temperature is too low can be completed, and then improve LCDs working temperature at low ambient temperatures, avoid the problem that hydraulic performance decline appears in LCDs at low ambient temperatures, ensure the performance of LCDs, improve serviceable life, extend the range of application of LCDs.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention.
