Logical, can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, for the ordinary skill in the art, can
To understand the concrete meaning of above-mentioned term as the case may be.
Fig. 1 is the principle of the VA liquid crystal indicator being applicable under strong light environment that this utility model first embodiment provides
Block diagram.As it is shown in figure 1, this VA liquid crystal indicator from top to bottom can be disposed with polaroid 100, upper conductive glass layer
200, liquid crystal layer 300, lower conductive glass layer 400, lower polaroid 500, semi-reflective and semitransmittable thin film 600 and backlight 700, wherein half is anti-
Semipermeable membrane 600 is arranged between lower polaroid 500 and backlight 700, and this semi-reflective and semitransmittable thin film 600 faces lower polaroid
The one side of 500 is reflecting surface, and the one side facing backlight 700 is transmission plane.
In the present embodiment, on this, polaroid, lower polaroid, upper conductive glass layer, lower conductive glass layer and liquid crystal layer can
To be all made up of full impregnated material, now the high light II in external environment condition can directly be transmitted through on semi-reflective and semitransmittable thin film.In conjunction with Fig. 2
Shown in, it is reflecting surface that semi-reflective and semitransmittable thin film 600 faces the one side of lower polaroid 500, when the high light II transmission in external environment condition
Time to semi-reflective and semitransmittable thin film 600, high light II is reflected back toward on lower polaroid 500.It addition, semi-reflective and semitransmittable thin film 600 faces
The one side of backlight 700 is transmission plane, and it is through lower inclined that the light source I that backlight 700 provides can penetrate this semi-reflective and semitransmittable thin film 600
Mating plate 500.The light source provided due to backlight can be directly transmitted to lower polaroid, and the high light II in external environment condition does not only have
There is the light source offset under being incident to that backlight provides on polaroid, enhance the light source being incident on lower polaroid on the contrary, by
This can reduce energy consumption on the basis of showing clearly ensureing character.
Wherein, this semi-reflective and semitransmittable thin film 600 can be made with plastics, adhesive, rubber or other materials.In order to ensure
Character reduces energy consumption on the basis of showing clearly further, and in the optional implementation of one, said apparatus can also include

Thoroughly offer regional transmission on thin film, so that the light source in external environment condition arrives backlight through this regional transmission, thus in backlight
On source arrange the brightness detected by testing circuit more can reflect character show during light source, in the brightness to backlight
It is controlled can improving accuracy further, such that it is able to reduce energy consumption further.
It addition, it has been investigated that, VA liquid crystal indicator, when showing character, is not that the brightness provided is got over
Height, the definition of character is the highest, but brightness is within the specific limits, and definition is the highest.Owing to VA liquid crystal indicator is daily
The external environment condition of maximum brightness is there is during use, it has been investigated that when semi-reflective and semitransmittable thin film is by maximum brightness in external environment condition
Light source completely (i.e. 100%) when reflexing to lower polaroid, the definition of character bad on VA liquid crystal indicator, i.e. half is anti-
Semipermeable membrane is by when in external environment condition, the light source of maximum brightness is entirely reflected to lower polaroid, it is thus achieved that light-source brightness not clearly
In the range of clear degree optimal brightness, therefore to expand the scope of application of VA liquid crystal indicator, in the present embodiment, half-reflection and half-transmission is thin
The emissivity of the surface of emission of film should be less than 100%, and its value and external environment condition light source maximum brightness and character sharpness are
Good brightness range is relevant.
Hereinafter the VA liquid crystal indicator in the present embodiment and current VA liquid crystal indicator are all placed in identical outside
Under environment, and backlight all provides the light source of same brightness, contrasts, specifically in terms of the definition and energy consumption two of character
Correction data as follows:
As seen from the above-described embodiment, this utility model is thin by arranging half-reflection and half-transmission between lower polaroid and backlight
Film, can reduce energy consumption on the premise of clearly showing ensureing character.
