Description
[technical field]
The utility model relates to a kind of light guide plate measurement mechanism, particularly a kind of light guide plate mesh point measurement mechanism that accurate reference location can be provided light guide plate mesh point.
[background technology]
Light guide plate is the key component in the planar light source devices such as LCD backlight system or preceding photosystem, and it cooperates the transmission direction of guiding light with pointolite or line source, and the light that this pointolite or line source sent is converted to equally distributed area source.
For realizing a plurality of sites of tool definite shape being set usually or offering a plurality of V-shaped grooves with light guide plate exiting surface opposed bottom surface by the even distribution of light guide plate emergent ray.When by light transmission that pointolite or line source sent during to this site or V-shaped groove, this site or V-shaped groove can destroy the total reflection condition of light in the light guide plate internal transmission, and light is transmitted to different directions, are finally penetrated by the light guide plate exiting surface.Utilize various densitys, the site that varies in size or V-shaped groove, can make light guide plate luminous evenly.
Wherein, this site can directly be printed on bottom surface of light guide plate by the screen painting mode, perhaps with non-mode of printing and light guide plate one ejection formation.Be easy to make because of the site again and convenient control size, density, it is than the uniformly light-emitting of the easier realization light guide plate of V-shaped groove, thereby is used widely.
But the design of the areal distribution characteristic of light guide plate mesh point such as size, thickness, phase mutual edge distance etc. needs usually by verification experimental verification, so that reach best design.Product quality detection-phase after this verification experimental verification stage and volume production all seems particularly important to the measurement of light guide plate mesh point areal distribution characteristic, check.
The prior art measurement mechanism of light guide plate mesh point is image instrument, microscope equidimension analyser normally.But, when adopting these dimension analysis instrument that light guide plate mesh point is measured,, only can carry out naked eyes and figure light guide plate mesh point to be measured position because of there not being any reference point, its measuring speed is slow, and easily miscounts, and is difficult for correct fast comparison.
Therefore, improve the light guide plate mesh point measurement mechanism, it is necessary improving light guide plate mesh point measuring speed and accuracy real.
[utility model content]
For overcome prior art light guide plate mesh point measurement mechanism measuring speed slowly, the problem of makeing mistakes easily, the utility model provides a kind of light guide plate mesh point measurement mechanism, this kind light guide plate mesh point measurement mechanism can improve light guide plate mesh point measuring speed and accuracy.
The technical scheme that the utility model technical solution problem is adopted is: a light guide plate mesh point measurement mechanism is provided, and it comprises a dimension analysis instrument and a positioning rule.This positioning rule comprises a thin slice and a plurality of regular distribution in the sign point of this thin slice, and these a plurality of sign points provide accurate reference location to light guide plate mesh point.
Compared to prior art, can provide correct location to the dot area to be measured of light guide plate because of the positioning rule of the utility model light guide plate mesh point measurement mechanism indicates point, be convenient to light guide plate mesh point accurately, measure fast, and help the comparison of standardized product and sample.

Fig. 4 is the schematic perspective view of the utility model light guide plate mesh point measurement mechanism, and wherein this positioning rule attaches mutually with light guide plate.
[embodiment]
As shown in Figure 1, be the three-dimensional exploded view of positioning rule 50 with the light guide plate 20 to be measured of the utility model light guide plate mesh point measurement mechanism.Wherein, this light guide plate 20 comprises an exiting surface 23, one and exiting surface 23 opposed bottom surface 22, and a plurality of sites 21 are arranged on the bottom surface 22 of this light guide plate 20.This positioning rule 50 comprises a thin slice (indicate) and a plurality of sign points 51, the size of this thin slice and light guide plate 20 exiting surfaces 23 or identical with site to be measured 21 area size of light guide plate 20.These a plurality of sign points 51 are dark round dots, and its regular distribution is on thin slice, and the density that this sign point 51 distributes on thin slice is less than the distribution density of site 21 in light guide plate 20 bottom surfaces 22.
Please cooperate with reference to Fig. 1 and Fig. 2, when this positioning rule 50 is used, can directly be attached at the exiting surface 23 of light guide plate 20 to be measured.Because this light guide plate 20 is to make with transparent material, be attached at the exiting surface 23 of light guide plate 20 when positioning rule 50 after, also can observe via the bottom surface 22 of light guide plate 20 and to indicate point 51.So, each indicates the i.e. a plurality of sites 21 in corresponding certain zone of point 51, thereby provides a reference point for a plurality of sites 21 in this zone.
As shown in Figure 3, be the another embodiment of the positioning rule of the utility model light guide plate mesh point measurement mechanism, this positioning rule 40 comprises a thin slice (not indicating) and a plurality of sign points, these a plurality of sign points are arranged at the numeral of sheet surface for rule.Certainly, these a plurality of sign points also can be the symbol or the pattern of other tool identification function.
This positioning rule 50 and 40 egative films that can use always make, and its material is generally polyester for film, and as polyethylene terephthalate etc., it also can be made of plastic.
As shown in Figure 4, it is the stereographic map of the utility model light guide plate mesh point measurement mechanism, and wherein this light guide plate mesh point measurement mechanism comprises dimension analysis instrument 30 and the positioning rule 50 that is attached at light guide plate 20.This positioning rule 50 can utilize 30 pairs of light guide plate mesh points of dimension analysis instrument to measure after fitting with light guide plate 20.The dimension analysis instrument 30 of present embodiment is a microscope, certainly, also can adopt other microscopic fields commonly used measurement, analytical equipment.
This dimension analysis instrument 30 comprises eyepiece 31, object lens 32, support 33, worktable 34, catoptron 35, base 36 and rocking handle 37.Wherein, this eyepiece 31 is arranged at support 33 upper ends with object lens 32, and object lens 32 are relative with worktable 34.This worktable 34 is in order to place the positioning rule 50 and light guide plate 20 after fitting, and catoptron 35 is in order to provide illumination, so that the site 21 of clear view light guide plate 20.Rocking handle 37 can be regulated the lifting of worktable 34, with accurate focusing.
The sign point 51 of the positioning rule 50 of the utility model light guide plate mesh point measurement mechanism can provide correct location to the dot area to be measured of light guide plate 20, is convenient to accurate, the measurement fast of light guide plate 20 sites 21, and helps the comparison of standardized product and sample.
This light guide plate mesh point measurement mechanism is except that the design verification that can be applicable to light guide plate mesh point, and it also can be applicable to the Quality Detection of volume production product; It can be applied to all other printing opacity series products of measuring with the dimension analysis instrument equally.
