Description
Technical field
The present invention relates to LCDs technical field, and in particular to a kind of liquid crystal display with automatic heating function
Screen.
Background technology
Traditional display mode such as CRT crt displays and LED display board etc., are all limited by that volume is excessive or power consumption
Very huge etc. factor of amount, it is impossible to reach the actual demand of user, and the development of lcd technology just suits current information production
The trend of product, either right angle show, low power consumption, small volume or the advantages of zero radiation, user can be allowed to enjoy optimal
Visual environment, but be a kind of organic compound, normality because liquid crystal is a kind of particular matter between a solid and a liquid
Under be in a liquid state, therefore the situation of hydraulic performance decline can all occur at low ambient temperatures in many LCDs, have impact on LCDs
Application.
The content of the invention
The present invention is intended to provide a kind of LCDs with automatic heating function.
The present invention provides following technical scheme：
A kind of LCDs with automatic heating function, it is characterised in that including for detecting that LCDs is worked as
The temperature sensor of preceding temperature；For detecting whether LCDs is in the detection module of running status；The detection module
Control module is connected to judge module, the control module is used to be according to the LCDs that detection judge module is exported
Whether the result of running status, the LCDs Current Temperatures that the control judge module is detected to temperature sensor are less than
Preset temperature threshold value is judged, and the judged result according to LCDs Current Temperatures less than preset temperature threshold value is fed back to
Plc data processor, the plc data processor controls automatic heating module to be heated by temperature control device, described
Automatic heating module is sent to LCDs after performing heating by temperature conduit, when LCDs temperature is higher than default temperature
Testing result is sent to control module by detection module during degree threshold value；Plc data processor is feedbacked data to by control module,
So as to which temperature control device is opened and closed.
The detection module is by detecting whether backlight that LCDs has judges liquid crystal in opening
Whether display screen is in running status.
The temperature controlled conduit is connected to the electrode strip that conductive silver paste is made on the relative both sides of glass substrate of liquid crystal display.
It is adjusted during the plc data processor inter-process data using the rule of PID proportional integral derivatives.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention detects LCDs using temperature sensor
Current Temperatures parameter, when LCDs is in running status, control module control judge module is operated, judge module
LCDs Current Temperatures are compared with preset temperature threshold value, are equal to default temperature when LCDs Current Temperatures are less than
Control module control heating module starts automatic heating during degree threshold value, and then improves the work of LCDs at low ambient temperatures
Temperature, it is to avoid the problem of LCDs hydraulic performance decline occurs at low ambient temperatures, has ensured the performance of LCDs, has carried
High service life, extends the application of LCDs.
