Abstract
The utility model discloses a kind of novel anti-dazzle cover boards, and including transparent substrate and the antiglare layer being sequentially arranged on the transparent substrate and rough layer, micron-sized inorganic particulate is distributed in the surface of the rough layer.Novel anti-dazzle cover board provided by the utility model can improve negative effect brought by sparkle phenomenon, improve picture display quality, extend the application range of anti-dazzle cover board while with dizzy function is resisted.
Description
Technical field
The utility model relates to field of display technology, more particularly to a kind of novel anti-dazzle cover board.
Background technique
The surface of display module generally all has one layer of glass cover-plate to protect to display module, and still, light is strong
In the case where strong, glass cover-plate meeting reflection light generates glare phenomenon, not only reduces the display effect of display module, and dizzy
Light will cause visual inadaptable sense, and strong dazzle can also damage vision or even induce blindness.To solve the above-mentioned problems,
Antiglare layer is generally set on glass cover-plate in the prior art.But existing anti-dazzle cover board is fitted in display equipment list
When face, although playing the role of anti-dazzle, the display picture that macroscopically human eye observation arrives is easily caused to occur simultaneously bright
The phenomenon that dark uneven or irregular colour, feel it is to occur many flashings " spark point ", this phenomenon quilt in picture to people
There is sparkle phenomenon and give people a kind of uncomfortable feeling in referred to as sparkle phenomenon, display equipment, and sparkle phenomenon with
The degree of difference " spark point " flashing of viewing visual angle is also different, brings great puzzlement to the use of people, seriously affects
The application range of display effect and anti-dazzle cover board, and do not find out preferably the method for improving sparkle phenomenon temporarily at present.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of novel anti-dazzle cover board.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of novel anti-dazzle cover board, including transparent substrate, the surface of the transparent substrate are rough anti-dazzle
Layer, the surface of the antiglare layer are formed with the rough layer containing micron-sized inorganic particulate, and coarse in the rough layer is write music
In line, when the horizontal 2H of peak counting is set to 50 μ inch, the peak number PPI of every 4mm is 200-400.
Further, the inorganic particulate is selected from silica, aluminium hydroxide, magnesium hydroxide, aluminium oxide, zirconium oxide and two
One of titanium oxide is a variety of.
Further, the rough layer with a thickness of 200nm-5um.
The utility model has the following beneficial effects:
Novel anti-dazzle cover board provided by the utility model can improve sparkle while with dizzy function is resisted
Negative effect brought by phenomenon, improves picture display quality, extends the application range of anti-dazzle cover board.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, transparent substrate, 2, antiglare layer, 3, inorganic particulate.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
A kind of novel anti-dazzle cover board, including transparent substrate, the surface of the transparent substrate are rough anti-dazzle
Layer, the surface of the antiglare layer are formed with the rough layer containing micron-sized inorganic particulate, and coarse in the rough layer is write music
In line, when the horizontal 2H of peak counting is set to 50 μ inch, the peak number PPI of every 4mm is 200-400.
It should be noted that so-called above-mentioned PPI here, is according to SAE J911 JUN86 (american car technical specification)
The value that defined method measures, it is indicated since the average line of roughness curve, is set respectively to two directions of positive (+) negative (-)
Fixed certain datum-plane H (therefore, width=2H of positive and negative datum-plane) will be more than negative datum-plane (- H, valley
Point) and when being more than positive datum-plane (+H, peak potion point), it is counted as 1.Before operation makes the counting reach evaluation length repeatedly, with
The number calculated disregards unit come the content indicated.Here, the width (2H) of positive and negative datum-plane is referred to as peak value
Count level is fixed value, is typically sized as 2H=50 μ inch.
The transparent substrate specifically can be any form of substrate such as glass, ceramic substrate or transparent plastic, herein
The utility model is not specifically limited.
The antiglare layer is to prevent dazzle from generating, and antiglare layer is the conventional structure of this field, to those skilled in the art
It is well known for member.
The utility model does not limit the specific manufacture craft of antiglare layer.Optionally, using spraying process or etch process,
Or frosting technology.Specifically, the spraying process specially sprays collosol and gel liquid on the transparent substrate, then solidify
The collosol and gel liquid forms rough glare prevention structure in groove surfaces.The etch process is specifically, transparent base
Plate chemically reacts in acidic mixed solution, and transparent substrate surface becomes uneven after reaction, so that anti-on surface
The reflected light non-directional shot out is realized light becoming diffusing reflection by mirror-reflection, weakens the interference to eyes, and light dirt is reduced
Dye avoids influencing visual effect.In order to enable transparent substrate surface reflectivity is inconsistent, the time is handled by adjusting differential responses
The antiglare layer of different roughness is obtained, the reflection case of antiglare layer is different, and optical parameter is different, and the degree of anti-dazzle is different,
In protection scope.
In the utility model, the inorganic particulate is selected from silica, silicon particle, aluminium hydroxide, magnesium hydroxide, oxidation
One of aluminium, zirconium oxide and titanium dioxide are a variety of, and but not limited thereto.
The rough layer with a thickness of 200nm-5um.
Inventor the study found that wave crest or trough density and anti-dazzle cover board in certain length display effect
Sparkle relationship is very big, and the wave crest or trough density in certain length are bigger, and sparkle phenomenon is slighter.Based on this, this reality
In novel, the rough layer containing micron-sized inorganic particulate is formed with by the surface in antiglare layer, makes high wave crest density
Anti-dazzle cover board, achieve the purpose that improve sparkle phenomenon.
The above-mentioned embodiments merely express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention, as long as using the form institute of equivalent substitution or equivalent transformation
The technical solution of acquisition, shall fall within the scope of the present invention.
