Description
Technical field
It is especially a kind of without interference flash-point glare proof glass the utility model relates to a kind of glass plate.
Background technique
External lateral light source causes the screen of electronic product to reflect strong light interference in order to prevent, and the vision for influencing user is distinguished
Not, the general of existing electronic product is equipped with anti-dazzle cover board on the screen, to reduce the intensity of external reflection light.Currently,
There are two types of the modes that anti-dazzle light processing is carried out in industry: one is spray anti-glare film on the surface of glass, anti-glare film is tree
Rouge material is made, and wearability is bad, it is caused to have the shortcomings that service life is short；Another kind is, to the surface of glass
Etching is learned, the roughness of glass surface is caused to rise, so that glass is generated the decline of specular gloss degree to extraneous light, but with gloss
The decline of degree also declines the clarity of screen imaging, or even interference flash-point occurs, leverages the effect of display.With
Display screen on electronic product clarity it is higher and higher, cause the glare proof glass of collocation as cover board in use, in glass
The interference flash-point occurred on glass cover board is also more and more obvious.Existing producer solves the problems, such as the master for occurring interfering flash-point on glass
Wanting mode is to improve the glossiness of glare proof glass；When implementing, by the glossiness at 60 ° of angles of glare proof glass under normal circumstances
It is promoted to 100~120SGU in 40~85SGU, although such mode solves the problems, such as interference flash-point occur, but with light
The raising of damp degree, the serious anti-dazzle light effect for affecting glass, makes glass lose the function of anti-dazzle.Therefore, it needs to design
It is a kind of out to be not only able to maintain the glossiness of existing glare proof glass, but also can solve the glass product of interference flash-point problem.
Utility model content
The purpose of this utility model is to provide a kind of without interference flash-point glare proof glass, this is without interference flash-point anti-dazzle glass
Glass is simple with structure, wear-resisting property is good, and long service life and the glossiness for being not only able to maintain existing glare proof glass also exist
Using when without interference flash-point occur the advantages that；The utility model also provide a kind of glass frosting etching solution with Preparation Method, can be real
The volatilization for reducing acid mist when present frosting etching, avoids the pollution of etching workshop condition；The utility model also provides nothing
Interfere the production technology of flash-point glare proof glass.
The technical solution of the utility model be achieved in that it is a kind of without interference flash-point glare proof glass, it is characterized in that
Including glass substrate, the glass substrate has incidence surface, and the another side opposite with incidence surface is light on the glass substrate

Average value.Ra measures the distance between the average value and " line " and gives the finger of the height of the pattern on etching surface
Show；
- Rz (amplitude) corresponds to " 10 mean roughness ", and is that average peak between 5 tops and 5 are minimum
The summation of average paddy between paddy.
- Rsm (distance values) is the average distance between two continuous passages by the profile of " bisector "；And this
Give average distance at these between " peak " and the therefore average value of the width of pattern.
Optical signature in the present embodiment is defined as follows:
Gloss, characterization, for example, brightness or the light on surface, and more specifically correspond to respect to ASTM standard
D523 is in the specular reflectivity on the surface of the reference substance (e.g., for example, certified black glass standard) of special angle, and
And it is indicated with SGU (standard gloss unit).
Penetrance is the ability for indicating light and penetrating medium, is to enter through the luminous flux of transparent or semitransparent body with it
The percentage of irradiating luminous flux.
Light transmission is diffused, be somebody's turn to do " mist degree " and (ii) by (i) and be somebody's turn to do " clarity " measurement: " mist degree " corresponds to wide
Diffusing transmission rate under the scattering of angle, and " clarity " corresponds to the diffusing transmission rate under the scattering of narrow angle.
The surface finish measurement of light-emitting surface 12 in the present embodiment is using 3D optical profilometer KEYENCE type VR-
3000, it is carried out in 10 millimeters of evaluation lengths and with the Gaussian filter that cutoff wavelength is 0.08 millimeter.
Whether judge at present has interference flash-point method occur on glare proof glass is: being distinguished by the direct observation of people
Not, it is green for first the screen of electronic product being arranged full frame when distinguishing, then by glass close to screen, eyes and the screen of people is leaned on
Nearly screen is 30~40cm at a distance from screen, observes whether glare proof glass interference flash-point occurs in this way.
The utility model is measured below by way of the light-emitting surface to 9 pieces of glass substrates, equally uses 3D optical profilometer
KEYENCE type VR-3000 is carried out in 10 millimeters of evaluation lengths and with the Gaussian filter that cutoff wavelength is 0.08 millimeter
Measurement, they are embodiment 2 respectively to embodiment 10, and the optical characteristics of each embodiment and the specific measured value of roughness are in following table
