Description
Technical field
The utility model relates to LCD design field, especially relates to a kind of WTN type LCD.
Background technology
LCD (the abbreviation of LiquidCrystalDisplay, i.e. LCDs), LCD has that driving voltage is low, power consumption is small, reliability is high, display contains much information, flicker free, to human body without harm, Automation of Manufacturing Process, the advantage such as with low cost, be a kind of desirable display equipment, be nowadays widely used on various instrument and meter.Mainly rely on the electrooptical effect of liquid crystal that electric signal is converted to the visible signal such as character, image in LCD.Under normal circumstances, its molecules align is very orderly for liquid crystal, seems as clear as crystal, once after adding DC electric field, the arrangement of molecule is upset, and a part of liquid crystal becomes opaque, color burn, thus can show numeral and image.And the Structural assignments of liquid crystal is different, make the kind of LCD a lot, and WTN type LCD is the one in now common LCD.
WTN (the abbreviation of WideviewingconeTwistedNematic, i.e. wide viewing angle cone twisted-nematic) the display comparison degree of type LCD, this class LCD is high, and driving voltage and low in energy consumption, but its visible limited viewing angle, in use can cause the inconvenience that user is certain.
Utility model content
It is high that the purpose of this utility model is to provide a kind of contrast, and structure is simple, and can carry out the display of full visual angle, the WTN type LCD at practical full visual angle.
According to an aspect of the present utility model, provide a kind of WTN type LCD of full visual angle, comprise that WTN flask is thick, top glass substrate, lower glass substrate, upper polarizer and lower polaroid, wherein thick, the lower glass substrate of upper polarizer, top glass substrate, WTN flask is connected successively with lower polaroid, and the thickness that WTN flask is thick is 2.8 μm-3.2 μm.
The beneficial effects of the utility model are: the utility model passes through the thick thickness of control WTN flask, and allow it coordinate other structures to use, its angles of display is made to be greater than the observable angle of human eye, namely user there will not be blind area from which angle views displaying contents of the present utility model, and the utility model can carry out the display of full visual angle.Structure of the present utility model is simple, and the contrast of display is high, and can realize the display of full visual angle, and practicality is high-strength.
In some embodiments, WTN flask is thick comprises WTN type liquid crystal, upper PI oriented layer, lower PI oriented layer, frame glue, upper ITO conductive layer and lower ITO conductive layer, wherein go up ITO guide layer, frame glue is connected successively with lower ITO guide layer, upper PI oriented layer, WTN type liquid crystal and lower PI oriented layer are all positioned at frame glue, and connect successively.Liquid crystal selects WTN type liquid crystal just can reach the display of full visual angle, frame glue is for limiting the position of liquid crystal, and the upper and lower PI (abbreviation of Polyimide, i.e. polyimide) oriented layer is to allow LCD molecular ordered arrangement make the display of LCD reliable, and the upper and lower ITO (abbreviation of IndiumTinOxide, i.e. tin indium oxide) conductive layer can strengthen electric conductivity and the transparency of top glass substrate, cuts off harmful electron irradiation and ultraviolet and infrared ray simultaneously.
In some embodiments, the refractive index of WTN type liquid crystal is 0.080-0.090.WTN type liquid crystal under this refractive index can obtain wider visible visual angle.
In some embodiments, the rubbing angle wherein going up PI oriented layer is 0 °-45 °.And the upper PI oriented layer under this rubbing angle can obtain wider visible visual angle.
In some embodiments, the rubbing angle of PI oriented layer is wherein descended to be 0 °-45 °.And the lower PI oriented layer under this rubbing angle can obtain wider visible visual angle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the WTN type LCD at the full visual angle of a kind of embodiment of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to figure 1, the WTN type LCD at full visual angle of the present utility model, comprises that WTN flask is thick 1, top glass substrate 2, lower glass substrate 3, upper polarizer 4 and lower polaroid 5.Upper polarizer 4, top glass substrate 2, WTN flask are thick 1, lower glass substrate 3 is connected successively with lower polaroid 5, and the thickness of WTN flask thick 1 is between 2.8 μm to 3.2 μm.
WTN flask thick 1 comprises WTN type liquid crystal 11, upper PI oriented layer 12, lower PI oriented layer 13, frame glue 14, upper ITO guide layer 15 and lower ITO guide layer 16.Upper ITO guide layer 15, frame glue 14 are connected successively with lower ITO guide layer 16, and form a box-shaped structure, and upper PI oriented layer 12, WTN type liquid crystal 11 and lower PI oriented layer 13 are all located in box-shaped structure, are namely located in frame glue 14, and connect successively.
The refractive index of WTN type liquid crystal 11 is between 0.080 to 0.090.In addition, upper PI oriented layer 12 and lower PI oriented layer 13 need to rub, the molecular energy of WTN type liquid crystal 11 is arranged according to rubbing angle, and the rubbing angle of upper PI oriented layer 12 is between 0 ° to 45 °, and the rubbing angle of lower PI oriented layer 13 is between 0 ° to 45 °.
