Abstract
The utility model discloses a liquid crystal display (LCD) appearance testboard capable of identifying observation angles. The LCD appearance testboard capable of identifying the observation angles comprises a base seat, a first polaroid, a light source, a support ring and a second Polaroid. The first polaroid is disposed on the base seat in embedded mode and used to support the first polaroid of an LCD, the light source is located below the first polaroid, the support ring is mounted above the first polaroid and provided with angel marks distributed along a circumferential direction, and the second polaroid is disposed on the support ring. The LCD appearance testboard capable of identifying the observation angles has the advantages of simple structure, convenient operation and good effect in detecting the LCD appearance.
Description
Technical field
The utility model relates to a kind of test board, especially a kind of LCDs outward appearance test board.
Background technology
LCDs is easy to produce in enormous quantities because of the integral module volume is little, in light weight, since substituting kinescope, has been widely used in electronic applications, shows product scope like video informations such as MP3, MP4, mobile phone, information telephone, industrial control equipment, instrument and meters.The structure of LCDs is in the middle of two parallel glass, to place liquid crystal, and the tiny electric wire of many vertical and levels is arranged in the middle of two sheet glass, controls shaft-like quartzy molecular changes direction through whether switching on, and light refraction is come out to produce picture.
Because the restriction of prior art; In the manufacture process of LCDs, LCDs bad order rate is always about 2%-3%, and these defective productss just are detected after assembling often; So just waste the parts that a lot of whiles have assembled, increased production cost.Person more very, some defective products needs the testing staff could find through 1-2 detection after assembling, has wasted great amount of manpower, has also reduced the quality of product integral body.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of LCDs outward appearance test board that can be used for detecting LCDs bad order article.
The utility model solves the technical scheme that its technical matters adopted: a kind of LCDs outward appearance test board of discerning observation angle is provided with:
Base;
Be inlaid in first polaroid that is used to carry LCDs on the described base;
Be positioned at the light source of described first polaroid below;
Be erected at the support ring of described first polaroid top, and this support ring is provided with the angle sign around circumferential distribution;
Be placed on second polaroid on the described support ring.
Laying of second polaroid is fixed with described support ring through support on the described base for ease, and described second polaroid is placed in the central area of support ring,
The central area of support ring also can be provided with glass plate, and the edge of glass plate and the inner edge of support ring interfix, and second polaroid is placed on this glass plate.
Second polaroid can freely rotate; Through rotating the mode of second polaroid; Need not the mobile liquid crystal display screen; Can carry out complete observation to the LCDs that is positioned on first polaroid from different perspectives, identify the angle of discerning rotation according to the angle on the support ring during rotation, be more convenient for comparison and operation.
For enough illuminations are provided to the workman, thereby make things convenient for workman's details operation, the top of described support ring is provided with illuminating lamp.
The beneficial effect of the utility model is: open the light source in the base; The light that sends through light source irradiation; The LCDs that is positioned on first polaroid is illuminated from the back side, and whether the LCDs of observing downwards under the illuminating state not from second polaroid top then has flaw, and the utility model LCDs outward appearance test board is simple in structure; Easy to operate, effective to the detection of LCDs outward appearance.
Description of drawings
Fig. 1 is the side view of the utility model LCDs outward appearance test board.
Fig. 2 is the vertical view (having omitted the illuminating lamp part among the figure) of the utility model LCDs outward appearance test board.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1, shown in 2; A kind of LCDs outward appearance of the utility model test board comprises that inside is provided with the base 1 of containing cavity 11; Be provided with light source 12 in this containing cavity 11, containing cavity 11 upper surfaces (being light source 12 tops) have first polaroid 13 that is used to carry LCDs.
For enough illuminations are provided to the workman, thereby make things convenient for workman's details operation, support ring 21 tops also are provided with illuminating lamp 4, and this illuminating lamp 4 is provided with towards base 1.
When the utility model LCDs outward appearance test board uses; Open the light source 12 in the base 1; Through the light that light source 12 irradiation is sent, the LCDs that is positioned on first polaroid 13 5 is illuminated, then from the back side; Second polaroid 3 from support 2 observes whether LCDs 5 has flaw under the no power state, to detecting of LCDs outward appearance.
Claims (2)
1. the LCDs outward appearance test board that can discern observation angle is characterized in that, is provided with:
Base;
Be inlaid in first polaroid that is used to carry LCDs on the described base;
Be positioned at the light source of described first polaroid below;
Be erected at the support ring of described first polaroid top, and this support ring is provided with the angle sign around circumferential distribution;
Be placed on second polaroid on the described support ring.
2. the LCDs outward appearance test board of discerning observation angle according to claim 1 is characterized in that the top of described support ring is provided with illuminating lamp.
