Abstract
A preparation method for high reliability liquid crystal display diffuser plate, is characterized in that: first, adopts sheet glass as substrate; Secondly, on substrate evenly or by certain graphic designs glue coating such as (" work " font, two " Y " or fish bone well figure); 3rd, diffusion barrier is fitted on glue, and applies in the space that pressure makes glue be covered with between diffusion barrier and substrate; 4th, make glue curing on substrate, substrate is formed the reliable glue-line of bonding; Finally, after glue curing, throw off diffusion barrier, the even smooth function of diffusion barrier is copied on glue-line, thus makes glass substrate become diffuser plate with even luminous energy power.The present invention has that temperature range is wide, anti shock and vibration ability strong, wet-heat resisting ability is strong and high reliability.
Description
Technical field
The present invention relates to a kind of lcd technology, especially a kind of manufacture method of liquid crystal display diffuser plate, specifically a kind of sheet glass that utilizes replaces organic material as the preparation method of the high reliability liquid crystal display diffuser plate of diffuser plate substrate.
Background technology
As everyone knows, reinforced liquid crystal displays is high because of self functional reliability, is widely used in the fields such as open air, vehicle-mounted, carrier-borne, Aero-Space.Due to the working environment of reinforced liquid crystal displays, its serviceability requires that more civilian LCD MODULE is more strict, to adapt to the rugged surroundings such as strong vibration, high humility, high temperature, low temperature.
Diffusion barrier is the important component part of liquid crystal display optics membrane module, play point-like or linear light source are launched optical haze, homogenising, cover the effect of lamp shadow.Diffusion barrier or the diffuser plate of existing liquid crystal display optics membrane module all adopt organic material, and temperature characterisitic depends primarily on material property, is easily out of shape under high and low temperature environment, affects the optical characteristics of diffusion barrier.Reinforced liquid crystal displays uses generally civilian diffusion barrier, easily occurs the phenomenon of film wrinkle distortion, easily occur the phenomenon that blooming be shifted, the picture quality that impact shows under strong vibration environment under high/low temperature, the working environment such as hot and humid.
Summary of the invention
The object of the invention is all to adopt organic material for the diffusion barrier of existing liquid crystal display optics film group or diffuser plate, temperature characterisitic depends primarily on material property, easily be out of shape under high and low temperature environment, affect the problem of the optical characteristics of diffusion barrier, invent and a kind ofly utilize sheet glass as substrate, glue as the preparation method of the high reliability liquid crystal display diffuser plate of film material.
Technical scheme of the present invention is:
A preparation method for high reliability liquid crystal display diffuser plate, is characterized in that:
First, adopt sheet glass as substrate;
Secondly, on substrate evenly or by certain graphic designs glue coating such as (" work " font, two " Y " or fish bone well figure);
3rd, diffusion barrier is fitted on glue, and applies in the space that pressure makes glue be covered with between diffusion barrier and substrate;
4th, make glue curing on substrate, substrate is formed the reliable glue-line of bonding;
Finally, after glue curing, throw off diffusion barrier, all light function of diffusion barrier is copied on glue-line, thus makes glass substrate become diffuser plate with even luminous energy power.
Described glue is the combination of one or more in silica gel, epoxy glue or UV glue.
The solidification on the glass substrate of described glue adopts one or both combinations in UV solidification, heat curing.
Beneficial effect of the present invention:
The material selection range of glue of the present invention is wide, simple to operate; The serviceability temperature scope of diffuser plate is wide, not yielding; Diffuser plate has stronger anti shock and vibration ability, wet-heat resisting ability, not easily off normal, than general diffusion barrier or diffuser plate reliability high.
The present invention is applicable to the fields such as various reinforced liquid crystal displays, outdoor liquid crystal display, has that temperature range is wide, anti shock and vibration ability strong, wet-heat resisting ability is strong and high reliability.
Accompanying drawing explanation
Fig. 1 is the present invention's glue by the cross-sectional view of diffusion barrier and glass gluing.
Fig. 2 is the cross-sectional view of diffuser plate of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1-2.
A preparation method for high reliability liquid crystal display diffuser plate, it comprises the following steps:
First, adopt sheet glass as substrate; The glass that sheet glass should adopt display industry conventional;
Secondly, on the glass substrate evenly by certain graphic designs (" work " font, two " Y " or fish bone well etc.) glue coating; Glue can adopt the one in the silica gel of one-component, epoxy glue or UV glue, also many component glues of several combination can be adopted, during many components, the ratio of each component is without particular/special requirement, and glue gets rid of bubble wherein preferably by vacuum, method that is centrifugal or the two combination before use.
3rd, diffusion barrier is fitted on glue, and applies in the space that pressure makes glue evenly be covered with between diffusion barrier and substrate; As shown in Figure 1.
4th, make glue curing on substrate, substrate is formed the reliable glue-line of bonding; Solidification or employing UV(ultraviolet light) solidify or heat curing, UV also can be adopted to solidify the curing combined with heat curing;
Finally, after glue curing, throw off diffusion barrier, the even smooth function of diffusion barrier is copied on glue-line, thus makes glass substrate become diffuser plate with even luminous energy power, as shown in Figure 2.
Details are as follows:
In Fig. 1,1 is diffusion barrier, and 2 is glue layers, and 3 is flat glass substrates.With reference to Fig. 1, glue adopts single component, bi-component or multi-component material, bi-component or polycomponent glue are prepared according to a certain percentage (single component glue does not need preparation), vacuum is passed through after mixing, bubble in colloid removes by mode that is centrifugal or the two combination, by glue evenly or by certain graphic designs (" work " font, two " Y " or fish bone well etc.) coating is on the glass substrate, joint movement is done again with diffusion barrier, the cloudy surface of diffusion barrier and glue-contact, applying certain pressure enables glue be extended to whole gaps between diffusion barrier and glass smoothly, after solidifying completely in glue, diffusion barrier is separated with the glue-line be attached on glass.
In Fig. 2,2 ' represents it is the glue-line of outside surface with even luminous energy power, and 3 is flat glass substrates.The even luminous energy power of diffusion barrier " is copied " to being attached to the glue-line of glass in appearance, and the glass of attachment glue-line just becomes the diffuser plate with even luminous energy power.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
