Abstract
The utility model discloses a backlight and liquid crystal display module, including gluing the frame and setting up the light guide plate in gluing the frame, the side of light guide plate is provided with the light emitting source, be provided with the heating plate on the play plain noodles of light guide plate, the heating plate is film + ITO structure. This backlight can be when the temperature be less than the zero degree, and automatic viscous, response speed become slow in case liquid crystal materials becomes for the LCD heating, have advantage frivolous, that combatting drop fall nature good for the heating plate of laminating under the LCD, can reduce because of the broken cost of maintenance who produces of screen.
Description
Technical field
This utility model relates to display field, particularly relates to a kind of backlight and liquid crystal display module。
Background technology
Usual liquid crystal display is very slow in the following response speed of zero centigrade, and when temperature is lower than 0 DEG C, liquid crystal material will become viscous, and response speed is slack-off, and dynamic image occurs that conditions of streaking even can not show。If temperature is too low, liquid crystal state will disappear, and becomes crystal, causes that liquid crystal display cannot normally show。This is for the user of field operation environment, particularly cold district, and problem is more prominent。
In prior art, installing heating plate additional to solve the problems referred to above typically via at liquid crystal display layer, heating plate is generally located between crystal liquid substrate and lower polaroid or lower polaroid is away from the side of crystal liquid substrate；Heating plate is generally glass+ITO structure, and anti-dropping capability is poor, and maintenance cost is big, and more thick and heavy。
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of backlight, and including glue frame and the light guide plate being arranged in glue frame, the side of described light guide plate is provided with luminous source, being provided with heating plate on the exiting surface of described light guide plate, heating plate is thin film+ITO structure。This backlight can when temperature is lower than zero degree, automatically to liquid crystal display heating in case liquid crystal material to become viscous, response speed slack-off；Relative to the mode of heating plate of fitting under LCD, there is advantage frivolous, that anti-drop is good, it is possible to reduce the maintenance cost produced because screen is broken。
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of backlight, including glue frame and the light guide plate being arranged in glue frame, the side of described light guide plate is provided with luminous source, and the exiting surface of described light guide plate is provided with heating plate。
Further, luminous source is connected to FPC, and described backlight FPC extends on light guide plate, and is fixed on light guide plate with double faced adhesive tape。
Further, described heating plate includes transparent base film and the zone of heating being arranged on transparent base film。
Further, the material of described transparent base film is high-transparent film material, such as PET or PC, but is not limited to this。
Further, the material of described zone of heating is low-resistance material, such as ITO or nanometer silver, but is not limited to this。
Further, described heating plate is connected to FPC by ACF or alternate manner, padded with sponge or other material without the region of heating plate FPC above backlight；Laminating double faced adhesive tape between heating plate FPC and backlight FPC, fixing heating plate FPC。
Further, described heating plate is connected to temperature sensor, for the temperature in monitor display。
Further, described light guide plate is provided with reflector plate away from the side of exiting surface。
Further, being provided with blooming between described light guide plate and heating plate, the setting of blooming by the limitation of optics film type or quantity, does not depend on different projects, and some project only has diffusion barrier, it does not have bright enhancement film；Some project is likely to the bright enhancement film only having or three (two) or more than three。
A kind of liquid crystal display module, including liquid crystal display layer and above-mentioned backlight。
Further, described liquid crystal display layer includes the lower polaroid, first substrate, second substrate and the upper polaroid that arrange from the bottom up successively。
This utility model have the advantages that this backlight can when temperature is lower than zero degree, automatically to liquid crystal display heating in case liquid crystal material to become viscous, response speed slack-off；Relative to heating plate of fitting under LCD, there is advantage frivolous, that anti-drop is good, it is possible to reduce the maintenance cost produced because screen is broken。
