Description
Technical field
The utility model relates to a kind of proving installation, more particularly, relates to a kind of proving installation that is used for adjusting between shield glass and the display screen test.
Background technology
Now, computing machine has been applied in every field such as industrial or agricultural, national defence, science and technology, education, management at large, and family and individual computed situation are also progressively popularized.
Computing machine is as a kind of data processing and storage system, and external electromagnetic field disturbs and may work the mischief to its normal operation and information security; As electronic equipment, radiation of itself and electromagnetic leakage may pollute the external electromagnetic environment or cause the information-leakage of self.In order to solve these harm and defective, generally adopt the mode of conductive shield, eliminate the interference of electromagnetic field.
As panel computer that form is arranged or reinforcing display, should guarantee the light transmission of form, guarantee the function of effectiveness, anti-information leakage again, industry generally adopts the silk screen shield glass to carry out electromagnetic screen.Present silk screen shield glass is to use two-layer tempered glass mostly, and the centre accompanies printing opacity, the electromagnetic silk screen of maskable, and adopts special warfare curing to form.Because it is good, easy to use that the silk screen shield glass has manufacture craft maturation, transmittance height, shield effectiveness, use very extensive in form radiation proof, information leakage field.Can prevent information leakage effectively by the silk screen shield glass, anti-electromagnetic interference (EMI), realize electromagnetic compatibility, can guarantee the light transmission of form again.
But because the characteristic of silk screen shield glass, the silk screen in the middle of it is formed by metal wire knitted, causes tinsel and tinsel intersection to have point of interface, is equivalent to have on shield glass a lot of little sites; Simultaneously, the screen of LCD display has a lot of picture elements.When we adopt the silk screen shield glass to be used as the shielding of LCD form, need the silk screen shield glass is placed on the LCD display front, silk screen point of interface and pixels of display screen will produce a little the interference of light with point at special angle, specific range, what see by naked eyes is exactly the interference point lines, so the generation Moire fringe can be subjected to the influence of Moire fringe when causing us to see through shield glass and see display screen.
In order to solve this visual problem, guarantee the function of silk screen shield glass simultaneously, can perhaps adjust the angle of shielding silk screen lines by regulating silk screen shield glass and display screen distance, reduce that silk screen point of interface and pixels of display screen are interfered and the bad visual effect that causes.Because of silk screen shield glass and display screen distance is determined by the product design of producer, and this distance is just determined when product design, generally can not change again, so if will reduce the influence of Moire fringe, generally can only be by adjusting the angle of shielding silk screen lines.
When at present manufacturer makes the silk screen shield glass always according to special angle such as several specifications such as 30 degree, 45 degree.But the intrinsic resolution of different display screens is not quite similar, the pixels of display screen of different size also has difference simultaneously, under the situation of different distance between display screen and the shield glass, also can produce Moire fringe, cause the silk screen shield glass can not well satisfy the demand of using producer like this, so the inreal generation of avoiding Moire fringe from the source of present this mode.If on the source, do not control the silk screen angle well, Moire fringe appears when assembling, and can cause display screen that very bad visual effect is arranged.And shield glass is disposable processing, and can not do over again, in case the silk screen angle can only be scrapped the new production of laying equal stress on this shield glass when not determining to cause bad visual effect, can cause very big economic loss like this.
At this situation, adopt the mode of manual setting at present: when design, determined the physical resolution of display screen, and the shielding silk screen layer is to the distance of display screen.Display screen is being kept flat, then the shield glass of zero degree silk screen is placed on above the display screen, to fill up by above-mentioned definite distance with mat between display screen and the shield glass, manual then rotation shield glass, when top view obtains preferably visual effect, manual measure angle between shield glass and the display screen, draw angle parameter with protractor.
This kind manual mode treatment effeciency is low, scratch display screen surface easily and cause damage, and artificial the adjustment and manual measuring angle, the data that obtain are inaccurate, keep flat display screen during debugging and also can not really simulate actual operating position, and can not multi-angle observe, can cause visual deviation like this.When manually debugging,, need be ready to the mat of corresponding height in advance for reaching the required distance between display screen and the shield glass.The design difference of different complete machines, the distance between display screen and the shield glass is also different, then needs to prepare again mat, and testing efficiency is very low.Whole test process needs the professional person just can carry out, and also can only place according to the angle of adjusting during the material check, estimates then, cannot check angle accurately, has the leak of quality restriction.
