Embodiment
The core of the present invention is to provide a kind of liquid crystal display die set.Conventionally, as liquid crystal display die set works
The limitation of principle, it usually requires to set a backlight that can be shone to produce light.And for carrying backlight at present
Liquid crystal display die set in, usual backlight can send 1200cd/m2The light of left and right, but finally through liquid crystal display mode
The brightness of the light of group only has 500cd/m2To 600cd/m2, this means that 50% or so light not by effective profit
With so can seem that the whole power consumption of liquid crystal display die set is higher at this stage.
And a kind of liquid crystal display die set provided by the present invention, pass through the non-display area in the first transparent substrate lower surface
Opto-electronic conversion module is set, opto-electronic conversion module can absorb the light in a part of external world and produce electric current, and then by that can fill
The current storage that battery produces opto-electronic conversion module, so as to greatly increase the cruising ability of rechargeable battery, phase
When in the power consumption for reducing liquid crystal display die set.
In order to make those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiment is only part of the embodiment of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, belong to the scope of protection of the invention.
Please refer to Fig.1, a kind of structure diagram for liquid crystal display die set that Fig. 1 is provided by the embodiment of the present invention.
Referring to Fig. 1, in embodiments of the present invention, the liquid crystal display die set includes setting the first of distribution successively from top to bottom
Transparent substrate 10, liquid crystal working lining 40, the second transparent substrate 20 and backlight layer 30；Wherein, first transparent substrate 10 is upper
Surface is fitted with the first polarizer 11, and second polarization is provided between second transparent substrate 20 and the backlight layer 30
Piece.
Since the product that the embodiment of the present invention is provided is liquid crystal display die set, wherein for setting various electrodes or work
The substrate of component needs to ensure good translucency, so above-mentioned first transparent substrate 10 needs to ensure with the second transparent substrate 20
Good translucency, under normal conditions the first transparent substrate 10 be made with the second transparent substrate 20 by glass.Certainly, related the
The specific material and specific size of one transparent substrate 10 and the second transparent substrate 20 are not done specifically in embodiments of the present invention
Limit.
Above-mentioned backlight layer 30 can be used as light source by incandescent lamp bulb, electrooptic panel, light emitting diode or cold-cathode tube etc.
Uniform light is produced upwards on the surface of backlight layer 30.Wherein, electrooptic panel can directly provide whole 30 surface of backlight layer
Uniform light, and other light sources then need to provide uniform light with the use of diffuser.
Backlight layer 30 can provide the light of any one color, such as yellow light, green light, blue ray, white
Coloured light line etc..The color for producing light for the backlight layer 30 in embodiments of the present invention is not specifically limited.Normal conditions
Under, whole liquid crystal display die set is when showing coloured image, it is necessary to which backlight layer 30 sends white light, because white light contains
The color category of light is most.
Certainly, the design parameter such as 30 thickness of related backlight layer is referred to the prior art, is no longer repeated herein.
The liquid crystal display die set that the embodiment of the present invention is provided generally is followed successively by the first transparent substrate 10, liquid from top to bottom
Brilliant working lining 40, the second transparent substrate 20 and backlight layer 30.Under normal conditions, it is provided with the upper surface of the first transparent substrate 10
First polarizer 11, and the second polarizer 21 is provided between the second transparent substrate 20 and backlight layer 30.The effect of polarizer
It is that the light for only allowing a default direction of vibration passes through the be arranged under normal conditions in same liquid crystal display die set
One polarizer 11 allows to be mutually perpendicular to by the direction of vibration of light with the second polarizer 21.Certainly, related first polarizer 11
The prior art is referred to the specific size of the second polarizer 21, in embodiments of the present invention and is not specifically limited.It is above-mentioned
The light that backlight layer 30 is sent can be adjusted to polarised light by the second polarizer 21.When polarised light by liquid crystal working lining 40 it
Afterwards, the direction of vibration of the polarised light can be twisted 90 degree, so by the first polarizer 11 by image display in liquid crystal display mode
The surface of group.
Due to liquid crystal 41 have liquid easy mobility, while liquid crystal molecule have have between anisotropy and liquid crystal molecule
Sequence arranges, i.e., the molecule of liquid crystal 41 has directionality.Under the action of not same electric field, liquid crystal molecule can be 90 degree of rows of rules rotating
