Description
[technical field]
The utility model relates to a kind of liquid crystal indicator that is used for the glass substrate of liquid crystal indicator and uses this glass substrate.
[background technology]
In recent years, along with the continuous development of liquid crystal indicator, its application is more extensive, as portable electric appts such as mobile phone, notebook computer, e-dictionaries.For satisfying the demand that is convenient for carrying, liquid crystal indicator needs to more lightening development.Make that liquid crystal indicator is lightening roughly a dual mode, promptly reduce the weight and the thickness of module backlight or reduce the weight and the thickness of display panels.
See also Fig. 1, it is a kind of synoptic diagram of prior art liquid crystal indicator, this liquid crystal indicator 10 comprises that a display panels 11 and is as the light-source system of this liquid crystal indicator 10 and be arranged at the module backlight 12 of these display panels 11 belows, this display panels 11 is disposed with polaroid 111 from the top down, be pasted with the top glass substrate 112 of colored filter, liquid crystal layer 113, upper surface is formed with the lower glass substrate 114 and the following polaroid 115 of thin film transistor (TFT), and this module 12 backlight comprises a light guide plate 121, one is arranged at the reflector plate 122 of these light guide plate 121 belows, one is arranged at the light source 123 of these light guide plate 121 sides, one is arranged at the diffusion sheet 124 and the prismatic lens 125 that is arranged at these diffusion sheet 124 tops of light guide plate 121 tops.
In this liquid crystal indicator 10, from light that light source 123 sends after light guide plate 121, be converted into area source by line source, incide diffusion sheet 124, after this diffusion sheet 124 spreads light, after via prismatic lens 125 light being concentrated again, reenter and be mapped to display panels 11 and do collocation with its visual angle, by the anglec of rotation of thin film transistor (TFT) control liquid crystal, the aperture opening ratio of control display panels 11 shows corresponding portrait thereby make in each pixel region.So, in this liquid crystal indicator 10, portrait shows to be needed can't make liquid crystal indicator 10 to more lightening development through more diaphragm.
[utility model content]
In order to overcome the bigger problem of prior art liquid crystal indicator thickness, the utility model provides a kind of frivolous, glass substrate that can replace prismatic lens in the liquid crystal indicator.
In order to overcome the bigger problem of prior art liquid crystal indicator thickness, the utility model provides a kind of frivolous, liquid crystal indicator that cost is low again.
The technical scheme that the utility model technical solution problem is adopted is: a kind of glass substrate is provided, comprises a bottom surface and a upper surface relative with the bottom surface, this bottom surface has prism array.
Another technical scheme that the utility model technical solution problem is adopted is: a kind of liquid crystal indicator is provided, comprise a top glass substrate and a lower glass substrate, upward clamping has a liquid crystal layer between the lower glass substrate, this lower glass substrate comprises a bottom surface and a upper surface relative with the bottom surface, and this bottom surface has prism array.
Compare with prior art, the beneficial effects of the utility model are: the bottom surface of the utility model glass substrate has prism array, and this prism array directly is formed at the bottom surface of this glass substrate.In the module backlight of prior art, light via the light guide plate outgoing after, its visual angle secundly, after the process diffusion sheet spreads light, after via one or two prismatic lens light being concentrated, do collocation with the visual angle of display panels again, its arranging effect is relatively poor usually.Glass substrate of the present utility model makes light after the bottom surface incident of this glass substrate, after the prism array of this bottom surface converges again from surperficial outgoing, collocation is done at light visual angle direct and display panels in the display panels that uses this glass substrate, because its can be directly and display panels do collocation and do not need any smooth medium, so its arranging effect is all good.Simultaneously because its prism array can play the effect of prismatic lens in the module backlight, so, use in the liquid crystal indicator of this glass substrate and need not use prismatic lens, can reduce liquid crystal indicator thickness and weight, reduce production costs.

[embodiment]
Seeing also Fig. 2, is the floor map of the utility model glass substrate first embodiment.This glass substrate 20 comprises a bottom surface 21 and a upper surface 22 relative with this bottom surface 21, and this bottom surface 21 has prism array 211, and the apex angle size of this prism array 211 is 90 degree.
This prism array 211 directly is formed at the bottom surface 21 of this glass substrate 20 in the utility model, so its weight is lighter.In the module backlight of prior art, light via the light guide plate outgoing after, its visual angle secundly, after the process diffusion sheet spreads light, after via one or two prismatic lens light being concentrated, do collocation with the visual angle of display panels again, its arranging effect is relatively poor usually.Glass substrate 20 of the present utility model makes light after bottom surface 21 incidents of this glass substrate 20, after the prism array 211 of this bottom surface 21 converges again from the upper surface outgoing, collocation is done at light visual angle direct and display panels in the display panels that uses this glass substrate 20, because its can be directly and display panels do collocation and do not need any smooth medium, so its arranging effect is all good.Simultaneously because its prism array 211 can play the effect of prismatic lens in the module backlight, so, use in the liquid crystal indicator of this glass substrate 20 and need not use prismatic lens, can reduce liquid crystal indicator thickness and weight, reduce cost.
Seeing also Fig. 3, is the side view of the utility model glass substrate second embodiment.The difference of this glass substrate 30 and the first embodiment glass substrate 20 is: the apex angle ss size of this prism array is 110 degree, and this upper surface 32 comprises thin film transistor (TFT) 321.
