Abstract
The invention relates to a liquid crystal display (LCD) device, comprising a first substrate, a second substrate opposite to the first one, and a liquid crystal layer placed in between the two substrates; and further comprising at least a heater which can heat the two substrates.
Description
[technical field]
The invention relates to a kind of liquid crystal indicator, the particularly a kind of liquid crystal indicator that in low temperature environment, can keep display quality.
[background technology]
Liquid crystal display is the image display format that generally adopts in present electronics or the information industry, because the liquid crystal itself in the liquid crystal indicator panel is not had a characteristics of luminescence, therefore for reaching display effect, need provide by a module backlight to show required light, this module backlight generally includes a light guide plate and a light source.
Seeing also Fig. 1, is a kind of existing liquid crystal indicator structural representation.This liquid crystal indicator 1 comprises a display panels 10 and a module 20 backlight, and this display panels 10 and module backlight 20 are oppositely arranged.
This display panels 10 comprises that one first substrate 11, second substrate 12 and relative with this first substrate 11 are sandwiched in the liquid crystal layer 13 between this first substrate 11 and second substrate 12.
This module 20 backlight comprises a light source 21 and a light guide plate 22, these light source 21 relative these light guide plate 22.The light that this light source 21 sends enters this display panels 10 through the transmission of this light guide plate 22, and the liquid crystal molecule by controlling this liquid crystal layer 13 (indicating) passes through with control light, and realizes the demonstration of this liquid crystal indicator 1.
This light source 21 be generally cold cathode ray tube (cold cathode fluorescent lamps, CCFL) or light emitting diode (light emitting diodes, LED).
But can there be following problem in this liquid crystal indicator 1 in use.The liquid crystal molecule of this liquid crystal layer 13 can be in the state of temperature balance with the external world, and promptly the temperature of this liquid crystal molecule can be subjected to the influence of ambient temperature.Under the environment of this liquid crystal indicator 1 at low temperature, be lower than the operating temperature of liquid crystal material when ambient temperature, just to cross the low reaction velocity that causes slow because of temperature can to make entire liquid crystal display device 1, dynamic response produces ghost down, contrast descends, or color inequality problems such as (mura), image quality also is affected.Can be when this light source 21 uses because luminous and produce heat energy, but limited for the temperature equilibrium influence of liquid crystal molecule, large size panel is especially obvious.
[summary of the invention]
In order to overcome the low problem of liquid crystal indicator display quality in low temperature environment in the prior art, be necessary to provide a kind of liquid crystal indicator of display quality of in low temperature environment, keeping in fact for necessary.
A kind of liquid crystal indicator comprises one first substrate, one second substrate relative with this first substrate, one is sandwiched in the liquid crystal layer between this first substrate and second substrate, and one is arranged on the colored filter between this first substrate and this liquid crystal layer, this liquid crystal indicator further comprises at least one heating arrangement, this heating arrangement is used to produce infrared luminous energy, and heats this first substrate and second substrate.Corresponding infrared ray absorbing material is set in this colored filter.
Compared with prior art, liquid crystal indicator of the present invention is provided with at least one heating arrangement, can produce infrared luminous energy, and corresponding infrared ray absorbing material is set in colored filter absorbs infrared luminous energy, reach heating first substrate and second substrate, keep the good display quality of this liquid crystal indicator in the lower environment of temperature.
[description of drawings]
Fig. 1 is the structural representation of prior art liquid crystal indicator.
Fig. 2 is the structural representation of liquid crystal indicator of the present invention.
Fig. 3 is first substrate shown in Figure 2 and the enlarged diagram of colored filter.
[embodiment]
Seeing also Fig. 2, is the structural representation of liquid crystal indicator of the present invention.This liquid crystal indicator 3 comprises a display panels 30 and a module 40 backlight, and this display panels 30 and module backlight 40 are oppositely arranged.
This display panels 30 comprises one first substrate 31, second substrate 32 and the liquid crystal layer 33 this first substrate 31 and second substrate 32 between relative with this first substrate 31.One colored filter 311 is arranged between this first substrate 31 and this liquid crystal layer 33.
This module 40 backlight comprises a plurality of light sources 41 and a light guide plate 42, and this light guide plate 42 comprises two incidence surfaces 421, and this light source 41 is these incidence surface 421 settings relatively respectively.The light that this light source 41 sends enters this light guide plate 42 and transfers to this display panels 30 through this incidence surface 421, and the liquid crystal molecule by controlling this liquid crystal layer 33 (indicating) passes through with control light, and realizes the demonstration of this liquid crystal indicator 3.
This light source 41 be generally cold cathode ray tube (cold cathode fluorescent lamps, CCFL) or light emitting diode (light emitting diodes, LED).
This liquid crystal indicator 3 also comprises at least one heating arrangement 44, and these heating arrangement 44 contiguous these incidence surfaces 421 are provided with.This heating arrangement 44 is infrared lamp (Infrared Ray Lamp) or infrared light-emitting diode, and this heating arrangement 44 links to each other with a temperature sensor (figure does not show), and this temperature sensor can be detected the temperature of this display panels 30.Cross when low when this temperature sensor detects these display panels 30 temperature, just activate this heating arrangement 44, produce infrared ray, and the light that sends with this light source 41 is by this display panels 30 that transfers to of this light guide plate 42.
Seeing also Fig. 3, is first substrate 31 shown in Figure 2 and the enlarged diagram of colored filter 311.This colored filter 311 comprise a black matrix (black matrix, BM) 312, a plurality of chromatic photoresist (R, G, B) 313 and one protective seam 314.Should be provided with at interval with this chromatic photoresist 313 by black matrix 312, this protective seam 314 is arranged between this black matrix 312, this chromatic photoresist 313 and this liquid crystal layer 33.Should deceive between matrix 312 and this protective seam 314 absorption layer 315 was set.The material of this absorption layer 315 is inorganic infrared ray absorbing materials, can absorb the infrared energy that this heating arrangement 44 produces, make win substrate 31 and second substrate 32 reach the effect of heating, the temperature that improves liquid crystal layer 33 makes this liquid crystal indicator 3 still can keep good display quality in the lower environment of temperature to required working temperature.This absorption layer 315 can be mercury cadmium telluride (HgC dTe), indium antimonide (InSb) or platinum silicide (PtSi).
If adopt organic infrared ray absorbing material to absorb the infrared energy that this heating arrangement 44 produces; then need not to be provided with this absorption layer 315; only need will this organic infrared ray absorbing material to mix this chromatic photoresist (R, G, B) 313 or protective seam 314 in; also can reach the absorption infrared energy, thus the effect of heating whole liquid crystal display panel 30.
Liquid crystal indicator of the present invention is provided with a heating arrangement, can produce infrared luminous energy, and corresponding infrared ray absorbing material is set in colored filter absorbs infrared luminous energy, reach heating first substrate and second substrate, keep the good display quality of this liquid crystal indicator in the lower environment of temperature.
