The passive-driving nematic positive liquid crystal display disclosed by the utility model has the characteristics of simple structure, light and thin product, stable process and the like, and has a better high/low-temperature display effect; and moreover, the liquid crystal compensation sheet TEP can perform double compensation for temperature and phase on the display box at multiple temperature points so as to realize a good display effect at different temperatures.
Description
Technical field
The utility model relates to a kind of LCD, particularly a kind of passive drive nematic erect image LCD.
Background technology
Existing ordinary passive drives super twisted nematic liquid crystal display (Super Twisted Nemetic on the market; Be called for short STN-LCD); The birefraction of liquid crystal can diminish along with the rising of temperature gradually in its box, makes under the high temperature liquid crystal and polaroid phase place not match to make it that at high temperature display effect is very poor.
Be illustrated in figure 1 as two super twisted nematic liquid crystal display Double STN (DSTN-LCD) of existing band temperature compensation function, polaroid 11, display box 12, TAC film 13, compensation box 14 and end polaroid 15 before comprising, wherein:
Preceding polaroid 11 and end polaroid 15 are used to make natural light to become linearly polarized light;
Display box 12 is realized the distortion of liquid crystal or non-warping through impressed voltage, and the collocation polaroid is realized showing or display message not;
But its complex structure, manufacturing process is loaded down with trivial details, and is very high to the box structural requirement, so production technology is restive.
The utility model content
In view of this, the utility model purpose is to provide a kind of passive drive nematic erect image LCD, has the heavy problem of temperature compensation function liquid crystal display device structure in the prior art to solve.
For realizing above-mentioned purpose, the technical scheme of the utility model comprises:
A kind of passive drive nematic erect image LCD ASTN-LCD comprises: end polaroid, the stn liquid crystal display box is provided with temperature compensation LCD panel TEP on the stn liquid crystal display box.
TEP described in the present embodiment comprises protective seam, polaroid, glue layer, liquid crystal LCP layer, TAC substrate layer, glue layer and the release layer of fitting successively, and said TEP fits on the stn liquid crystal display box.
The phase place of the display box of stn liquid crystal described in the present embodiment be 830+/-5mm, twist angle is 240 °, the phase place of said TEP be 655+/-5mm.
Can find out from such scheme; The disclosed ASTN-LCD of the utility model embodiment; Be employed in and be provided with the temperature compensation that temperature compensation LCD panel TEP realizes LCD on the stn liquid crystal display box, compare two box super-twist nematic DSTN temperature compensation erect image products, have simple in structure, product is frivolous; Characteristics such as process stabilizing; And liquid crystal compensation sheet TEP can carry out temperature and the dual compensation of phase place to display box at a plurality of temperature spots, thereby can realize display effect preferable under the different temperatures.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of passive drive nematic erect image LCD ASTN-LCD, comprising: end polaroid, the stn liquid crystal display box is provided with temperature compensation LCD panel TEP on the stn liquid crystal display box.
In the present embodiment,, realized temperature compensation, and simplified the structure of existing temperature compensation LCD LCD through on the stn liquid crystal display box, being provided with TEP.
The utility model discloses following specific embodiment; With the phase place be 830+/-the 5mm twist angle is that 240 ° STN-LCD is an example; Through in phase place be 830+/-the 5mm twist angle be fit on 240 ° the super-twist nematic liquid crystal display STN display box increase a phase place be 665+/-the temperature compensation LCD panel TEP of 5mm; Realize promptly compensating display effect with the erect image of phase compensation function again with temperature compensation; Its structure is as shown in Figure 2, comprises temperature compensation polaroid 21, stn liquid crystal display box 22 and end polaroid 23, and is as shown in Figure 3; Wherein TEP is made up of diaphragm 211, polaroid 212, glue layer 213, liquid crystal LCP layer 214, TAC base material 215, glue layer 216 and release layer 217 in order, is illustrated in figure 4 as the one-piece construction synoptic diagram of the disclosed ASTN-LCD of present embodiment.
Temperature compensation liquid crystal polaroid 21 is used for temperature compensation, under each temperature this polaroid all can be well with the STN box in liquid crystal phase mate, thereby obtain preferable high low temperature display performance;
Stn liquid crystal display box 22 is used to mate the temperature compensation LCD panel;
With the 1.1mm thickness glass is example, and the whole maximum ga(u)ge of ASTN product is merely 3.0mm, and DSTN product maximum ga(u)ge then is 5.5mm, and the ASTN product thickness is about the half the of DSTN product.Hence one can see that, and than DSTN temperature compensation erect image product, that ASTN has is simple in structure, product is frivolous, the characteristics of process stabilizing.
In the present embodiment, TEP is arranged on the stn liquid crystal display box through the method for fitting, and in addition, the TEP in the present embodiment must adopt the TEP material with temperature compensation function, adopts other material can not realize the effect of temperature compensation.
Present embodiment do not limit can only be applied in phase place be 830+/-the 5mm twist angle is on 240 ° the STN-LCD, the LCD that the phase compensation value of twist angle that it is concrete and the TEP that selects to different twist angles can compensate according to the needs of reality is set.
Present embodiment selects for use TEP to carry out temperature and the dual compensation of phase place to display box at a plurality of temperature spots, thereby can realize display effect preferable under the different temperatures.As shown in Figure 5, have the LCD ASTN-LCD of temperature compensation function, the contrast under different temperatures is all high than conventional DSTN, FSTN erect image LCD, and promptly its high low temperature display effect is better than DSTN, FSTN erect image product.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
