Abstract
The utility model relates to a LCD display with inhibitory coating. In order to solve the problems of easy scoring and inconvenient cleaning resulting from liquid crystal glass of the LCD directly facing exterior, a shell window of the LCD is provided with a transparent sheet of protective effect positioned outside the liquid crystal glass. The transparent sheet had better to be made from high-hardness whole-permeable dense optical material and its surface may be coated with glare-protective low-reflective coating and antifouling coating. Since increasing the protective transparent sheet, the fragile liquid crystal has the firm shield to prevent scratch and damage. Besides, the transparent sheet can further reduces the reflection of exterior rays. Accordingly, it can reduce the damage to human eyes when using computers for a long time. Moreover, when the surface is dirty, it can be cleared conveniently on working state. for all the above characteristics, the LCD of the utility model can be also called an eye-lubricating screen.
Description
Technical field
The utility model relates to the LCD that is connected with office or household PC, more particularly, relates to a kind of LCD that is referred to as the band protective layer of eye-lubricating screen.
Background technology
In recent years, lcd technology has obtained continuous development; Compare with the conventional picture tube escope, LCD have volume little, put convenient attractive in appearance, electromagnetic radiation is little, to advantages such as the human eye injury are little, so replaced traditional monitor gradually in a lot of local liquid crystal displays, become the preferred accessory of office or household PC.The display screen of LCD is constituted by filling up liquid crystal material in two blocks of glass sheet usually, because liquid crystal has the character of stickiness (viscosity), elasticity (elasticity) and polarizability (polarizalility), therefore work as electrode by changing the characteristic of polarisation.In order to make it show image, the top in the middle of two blocks of glass sheet becomes 90 conductors of spending mutually with the bottom permutation inter, and each point of crossing is exactly a unit, by exporting corresponding signal to per unit, just can control corresponding image and show.
Except that the liquid-crystalline glasses sheet of dress liquid crystal material in above-mentioned, existing LCD also comprises support usually, be loaded on housing on the support, be loaded on control circuit in the housing etc.Wherein, the edge that has the liquid-crystalline glasses sheet of liquid crystal material is loaded in the housing, and the surface then adds any protection ground directly in the face of outside, and this do not have following shortcoming with the LCD of protection:
(1) when LCD is in open state,, will produce the same demonstration distortion of ripples line if there is foreign matter to touch the surface of display;
(2) the liquid-crystalline glasses sheet is scratched by foreign matter easily even damages fully;
(3) when there are dust or stain in liquid-crystalline glasses sheet surface, need extreme care to clear up.
The utility model content
At the above-mentioned defective of prior art, the utility model will solve in the available liquid crystal display because its liquid-crystalline glasses sheet directly damages, cleans problems such as inconvenience in the face of the outside easy scuffing that is produced.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of LCD with protective layer, comprise the housing that is provided with display window, be loaded on the control circuit in the housing and be loaded on housing window place and the liquid-crystalline glasses sheet of interior dress liquid crystal material; Wherein, a light transmission piece that plays protective action that is positioned at described liquid-crystalline glasses sheet outside also is housed at described housing window place.
In the utility model, described light transmission piece is preferably the fine and close optical material of high rigidity whole-permeable and makes.
In the utility model, preferably also scribble the low reflectance coating of anti-dazzle on the surface of described light transmission piece.Surface at the low reflectance coating of described anti-dazzle preferably also scribbles nonpolluting coating.
In the utility model, preferably also scribble the low reflectance coating of anti-dazzle on the surface of described liquid-crystalline glasses sheet.
By such scheme as can be known, the utility model has been set up a protective transparent sheet at the display window place of available liquid crystal display, makes fragile liquid crystal have firm shield, is difficult for scuffing, more not fragile, thereby can increases the service life more than 45%; This light transmission piece can also further reduce the extraneous light reflection, thereby can slow down the injury that long-time use computer causes human eye; When there is stain on its surface, under open state, also can wipe nursing easily clearly, very easy to use.Owing to have These characteristics, LCD of the present utility model can be described as---eye-lubricating screen.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the front view of the LCD in preferred embodiment of the utility model;
Fig. 2 is the rear view of LCD shown in Fig. 1;
Fig. 3 is the left view of the back cover of LCD shown in Fig. 1
Fig. 4 is the A-A cut-open view of the face-piece of LCD shown in Fig. 1.
Embodiment
A preferred embodiment of the present utility model as shown in Figures 1 to 4.As can be seen from the figure, the agent structure of this LCD 100 and available liquid crystal display are roughly the same, and its housing is made up of face-piece 101 and back cover 102, during assembling, cooperate by buckle structure and/or screw retention between face-piece and the back cover.
Wherein, the control circuit of display is located in the housing (not drawing in the drawings), and a plurality of control buttons then are located at the bottom on face-piece 101 surfaces.
Can find out the structure of face-piece display window from Fig. 1 and Fig. 4, wherein, label is the liquid-crystalline glasses sheet of dress liquid crystal material in 103 position is used to install, and label is the light transmission piece that 104 position then is used to install protective action.Light transmission piece is loaded on liquid-crystalline glasses sheet outside, can be close to installation between the two, and a suitable little gap also can be arranged.During concrete the installation, light transmission piece can be passed through one or more and the face-piece secure fit in the modes such as buckle, screw, viscose glue.
Light transmission piece in the present embodiment is to be made by the fine and close optical material of high rigidity whole-permeable, for example can be tempering optical glass, acrylic etc.Also scribble the low reflection of anti-dazzle (Anti-glare lowreflection) coating on its surface; Surface at the low reflectance coating of anti-dazzle also further scribbles nonpolluting coating.In addition, also scribble the low reflectance coating of anti-dazzle on the surface of liquid-crystalline glasses sheet.
By the foregoing description, the utility model has been set up a protective transparent sheet at the display window place of available liquid crystal display, makes fragile liquid crystal have firm shield, is difficult for scuffing, more not fragile, thereby can increases the service life more than 45%; Be used to have the protection of light transmission piece, when hand or foreign matter are pressed in display surface, also can produce corrugated and show distortion.
Owing to all scribble the low reflectance coating of anti-dazzle at liquid-crystalline glasses sheet and light transmission piece surface, so this liquid crystal Display can minimize the extraneous light reflection, dazzles thereby thorough elimination causes the screen of eye fatigue Light makes user's vision more comfortable, and display effect is also better, thereby can slow down long-time use computer pair The injury that human eye causes.
In addition, owing to be provided with nonpolluting coating on the light transmission piece surface, thus can reduce the dust accumulation, and protection against the tide is arranged The effect of oil-stain-preventing, in the regular maintenance, a wiping can reach cleaning effect gently, thereby can thoroughly break away from existing The problem that has liquid crystal display to be difficult to nurse.
