Abstract
The utility model discloses a liquid crystal display (LCD) which can be adaptable to vacuum environment, which comprises a liquid crystal module set and a backlight module set, wherein a liquid crystal box is acted as the liquid crystal module set and is made into a seal box which is made of two glass basal plates, and liquid crystal materials are filled in the liquid crystal box. Both sides of the liquid crystal box are provided with two pieces of toughened glass in an adhesive joint way, and the liquid crystal box and the toughened glass are formed into a whole body. The backlight module set comprises a light conducting plate and a light emitting source of the liquid crystal display (LCD) which is arranged at the side face of the light conducting plate, and an optical membrane is arranged above the light conducting plate. The utility model belongs to a liquid crystal display which can overcome various problems of the liquid crystal display and can normally work under the vacuum environment consequently, and the problems of the liquid crystal display are brought from low pressure in the vacuum environment.
Description
Technical field
The utility model is mainly concerned with field of liquid crystal, refers in particular to a kind of LCD that is adapted to work under the vacuum environment.
Background technology
In the prior art, LCD mainly is made up of liquid crystal module and module backlight, and wherein the critical piece of liquid crystal module is a liquid crystal cell, and liquid crystal cell is the seal box of being made by the layer glass substrate, and the inside is full of liquid crystal material.Liquid crystal cell external and internal pressure under normal pressure is a balance, but under vacuum environment, the liquid crystal cell ambient pressure reduces, and inner owing to be hermetically-sealed construction, pressure is constant, and liquid crystal cell outwards will produce bigger pressure reduction like this.Just may cause liquid crystal cell to break when pressure reaches certain order of magnitude, the liquid crystal outflow causes LCD normally not show.
In general, that the backlight liquid crystal display module adopts is cold-cathode fluorescence lamp (CCFL), and the CCFL fluorescent tube is to need high-voltage alternating to drive, and the trigger voltage of general lamp tube starting is more than the 1500V, normal working voltage is at 500～600V, and such high pressure is produced by the inverter of display interior.Under hypobaric, the insulativity of air can reduce, and the inverter of high pressure is to be easy to occur discharge " sparking " phenomenon as being used under the vacuum environment, will cause damage to inverter in case " sparking " phenomenon occurs, even damage other components and parts of display interior, cause heavy losses.Simultaneously, inverter has stronger electromagnetic radiation in the course of the work, to monitor signal and on every side electronic equipment can cause certain interference.
The utility model content
The technical problems to be solved in the utility model just is: the technical matters at prior art exists can overcome in the vacuum environment because the variety of problems that infrabar brings to LCD can be in the LCD of operate as normal under the vacuum environment thereby the utility model provides a kind of.
In order to solve the problems of the technologies described above, the solution that the utility model proposes is: a kind of LCD that adapts to vacuum environment, it comprises liquid crystal module and module backlight, described liquid crystal module is a liquid crystal cell, liquid crystal cell is the seal box of being made by the layer glass substrate, and the inside is full of liquid crystal material; It is characterized in that: be provided with in the liquid crystal cell both sides by two blocks of bonding tempered glass of bonded adhesives, liquid crystal cell and tempered glass form an integral body; The LED light emitting source that described module backlight comprises light guide plate and is located at the light guide plate side, the light guide plate top is provided with blooming.
Compared with prior art, advantage of the present utility model is:
1, the liquid crystal cell in the LCD of the present utility model adopts the method for laminated glass embedding, paste a tempered glass (transmittance is more than 90%) at liquid crystal cell glass substrate outermost, in the liquid crystal cell inboard, be close to a tempered glass equally, simultaneously around with they with liquid crystal cell envelope frame glue carry out bonding make it into as a whole.Because the aerial organic glass that is adopted and the intensity of tempered glass are very big, therefore are enough to bear the pressure that LCD is produced by inside and outside differential pressure under vacuum environment, thereby have guaranteed the operate as normal of LCD under vacuum environment;
2, the backlight in the LCD of the present utility model does not adopt traditional CCFL backlight, but adopts the white light LEDs backlight.The white light LEDs backlight adopts low-voltage DC supply, and generally below direct current 12V, such low pressure parts do not have " sparking " phenomenon under vacuum environment.Simultaneously, backlight adopts low-voltage DC supply, and electromagnetic radiation intensity is low, not can to monitor signal and on every side electronic equipment cause interference;
3, LCD of the present utility model can also structure of modification obtains by carrying out simply to the common liquid crystals display, makes that common LCD also can be in operate as normal under the vacuum environment behind structure of modification simply.

Embodiment
Below with reference to accompanying drawing the utility model is described in further detail.
As Fig. 1, Fig. 2 and the utility model specific embodiment shown in Figure 3, the utility model LCD mainly is made up of liquid crystal module and module backlight, wherein the critical piece of liquid crystal module is a liquid crystal cell 2, and liquid crystal cell is the seal box of being made by the layer glass substrate, and the inside is full of liquid crystal material.Be provided with two blocks of tempered glass 1 in liquid crystal cell 2 both sides, use high transmission rate bonded adhesives 22 bonding each other, the transmitance of this bonded adhesives 22 is very high, can not cause obvious influence to the brightness of liquid crystal cell 2.Become an integral body with envelope frame glue 21 with liquid crystal cell 2 and tempered glass 1 are bonding in the bonding sides of liquid crystal cell 2, thereby play the purpose that liquid crystal cell will be reinforced for 2 day after tomorrow, make liquid crystal cell 2 can bear big pressure under the vacuum environment.
Adopt white light LEDs as backlight in the utility model backlight liquid crystal display module, this module backlight mainly comprises white superbright LED light emitting source 5, high efficiency light guide plate 4, PCB printed board 7 and blooming 3.Blooming 3 comprises scattering film 33, brightness enhancement film 32, the prism film 31 in light guide plate front in the present embodiment, and at the reflectance coating 6 of light guide plate 4 bottom surfaces and side.Wherein white superbright LED light emitting source 5 is positioned at high efficiency light guide plate 4 sides, and PCB printed board 7 is positioned at White LED light emitting source 5 outsides and is attached thereto.Be placed with brightness enhancement film 32 and the prism film 31 that makes luminous uniform scattering film 33 and increase brightness in light guide plate 4 fronts.
